Objective To investigate the efficacy and safety of PAD regimen in previously untreated patients with multiple myeloma(MM). Methods We retrospectively analyzed 54 patients with newly-diagnosed MM,who were treated with PAD regimen: Bortezomib 1.3mg/m² subcutaneously on day 1,4,8,11. Liposomal doxorubicin 25～30 mg/m² intravenously on the first day. Dexamethasone 40 mg/d intravenously or orally on days 1～4. Treatment was repeated every 21 days. Response was evaluated according to the International Uniform Response Criteria for MM.Adverse events were graded according to the National Cancer Institute Common Toxicity Criteria,version 3.0. Results ①Overall response:after median 4(2～8) courses of PAD,47patients(87.0%)responsed,including complete response (CR) in 20 (37.0%),very good partial response (VGPR) in 19 (35.2%),partial response (PR) in 8 (14.9%),stable disease (SD) in 5 (9.3%) and progressive disease (PD) in 2 (3.7%). ②Subgroups efficacy: among the 54 patients,35 patients received more than 4 therapeutic courses,and 19 patients received less than 4 courses.The ORR was 97.1% (34/35) and 68.4% (13/19) respectively (P=0.003). Subgroups efficacy were compared according to age,renal function,number of bone destruction,proportion of bone marrow plasma cells,ALB,LDH,β2-MG,cytogenetics,ISS staging and clinical classification. The results indicated that there was no statistical difference(P>0.05). ③Overall safety: adverse events included neutropenia in 8 (14.8%),thrombocytopenia in 8 (14.8%),peripheral neuropathy in 16 (29.6%),diarrhea in 2 (3.7%),constipation in 2 (3.7%),herpes zoster in 4 (7.4%) and bacterial infection in 5 (9.3%). The adverse events relieved or disappeared after symptomatic treatment. ④Subgroups safety: compared by age and courses of treatment,the incidence of overall adverse events and grade 3/4 adverse events in patients older than 60 years and ones younger than 60 were 47.4% vs 60.0% and 15.8% vs 20.1% respectively,(P=0.404,P=1.00). The incidence of overall adverse events and grade 3/4 adverse events in patients with more than 4 therapeutic courses and ones with less than 4 courses were 57.9% vs 54.3% and 21.2% vs 17.1% respectively,(P=1.00和P=0.728). Conclusion PAD regimen has really curative effect in treating patients with newly diagnosed MM. There is a correlation between remission rate and therapeutic courses. It can be used as the first selected protocol for the induction therapy of MM. Its efficacy is independent of traditional prognostic factors.Liposomal doxorubicin has almost no cardiotoxicity. Replacing traditional anthracycline doxorubicin,the adverse events are controllable and the tolerance is generally well. PAD regimen is more proper to be applied to older patients with MM.

Objective To compare the short-term clinical effects difference between analgesic tincture and topical nonsteroidal anti-inflammatory drugs (NSAIDs) in the treatment of lateral epicondylitis (LE). Methods 60 cases of LE patients were randomly divided into an analgesic tincture group (n=30) and a NSAIDs group (n=30). Analgesic tincture was chosen for the analgesic tincture group and topical ketoprofen gel for the NSAIDs group to treat LE. Two groups were treated continuously for 3w, 3 times/day. Clinical results of each drug were followed-up at the time point of 3w, 6w and 12w after usage. Observational indexes included the visual analogue scale (VAS), disabilities of the arm, shoulder and hand questionnaire (DASH) and pain-free grip strength (PFGS). The inter-group difference of VAS (at activity), VAS (at rest), DASH score and PFGS were compared subsequently. Results No difference of the VAS (at activity), VAS (at rest), DASH score were ascertained (P> 0.05) between groups. Inter-group difference of PGFS was also not discerned at the time points of pre-treatment and 3 weeks and 6 weeks (P=0.91, P=0.42, P=0.13) post-treatment. However, PFGS of the analgesic tincture group was found to be higher than that of the NSAIDs group (P=0.02) after 12 weeks post-treatment. Conclusion Effect of analgesic tincture in releasing pain is almost the same to that of tropical NSAIDs, but a better effect in improving muscle strength.

Objective To observe the effect of pregabalin combined with mecobalamin on acute pain after lumbar surgery. Methods A total of 60 patients underwent single lumbar spine surgery in our hospital from January 2019 to December 2019. The incisions of patients were routinely infiltrated around the incision with 0.375% ropivacaine 20 mL. Patient-controlled intravenous analgesia (PCIA) was used. The patients were randomly divided into two groups. The experimental group: oral pregabalin 75mg bid and intravenous mecobalamin injection 0.5mg qd 1 day before surgery, five days in total. Control group: oral pregabalin 75mg bid and intravenous injection of equal volume of saline 1 day before surgery, five days in total. The VAS scores of preoperative and postoperative 6, 12, 24, and 48 h were observed. JOA scores were performed before surgery, 24 h after surgery, and 48 h after surgery. The doses of opioids, PCIA pressing times, remedial medications and adverse reactions were recorded at 24 h and 48 h after surgery. Results There was no significant difference in VAS scores between the two groups within 12 h after surgery, but the resting VAS and exercise VAS scores in the experimental group were lower than those in the control group during the period of 12～48 h (P<0.05). The amount of sufentanil, the pressing times of PCIA and the average remedial medication in the experimental group were lower than those in the control group at 24 h and 48 h after operation (P<0.05). There were no significant differences in JOA scores and adverse reactions between the two groups (P>0.05). Conclusion Pregabalin combined with mecobalamin in patients with lumbar spine surgery has good postoperative analgesia and low incidence of adverse drug reactions, but more randomized controlled trials are needed to confirm the safety and efficacy.

Objective To explore the value of ultrasound combined with different methods in improving the detection rate of patent foramen ovale. Methods 88 cases of clinically suspected patent foramen ovale in our hospital were collected as the research objects to carry out the ultrasonic image group examination (routine transthoracic echocardiography TTE, transesophageal echocardiography TEE, right heart contrast echocardiography), and the results of multiple groups of ultrasonic image examination were recorded for retrospective statistical analysis. Results Among 88 subjects, 12 (13.6%) were found to have PFO (+)by conventional transthoracic echocardiography, 2 of them had atrial septal aneurysm. 20 cases (90.9%) of PFO were found by transesophageal ultrasonography, and two of them were from pulmonary arteriovenous fistula.In all the subjects, 39 cases (44.3%) of PFO were found by right heart sonography, 24 cases were found in resting state, 39 cases were found after Valsalva operation, 4 cases were found with aneurysm of atrial septum, 3 cases with pulmonary arteriovenous fistula (one of them was from pulmonary vein). Among the 14 patients examined by transesophageal ultrasound combined with right cardiac sonography, 10 (71.4%) were found to have PFO(+). According to the number of microbubbles, the right echocardiography showed that there were 16 cases in grade I, 5 cases in grade II, 18 cases in grade III, and there were statistical differences in the semi quantitative classification of RLS in different states (χ²=12.729, P=0.02). Conclusion Ultrasound image histology can be used for semi quantitative evaluation of patients with patent foramen ovale, which can effectively supplement the lack of single conventional ultrasound information, and provide objective basis for clinical diagnosis and treatment.
