Objective To investigate the clinical characteristics and its related influence factors of hyperuricemia in peritoneal dialysis patients. Methods A total of 152 peritoneal dialysis patients were enrolled. Patients were classified into hyperuricemia and normal serum uric acid (SUA)groups. Factors associated with hyperuricemia were analyzed. Results Hyperuricemia occurred in 112 cases(73.7%). There were significant differences in serum potassium, the incidence of hypertension, blood urea nitrogen, serum creatinine, serum phosphorus, parathyroid hormone, triglyceride between hyperuricemia and normal SUA groups(P<0.05). There was no significant difference in age, serum sodium, hemoglobin, serum albumin, prealbumin, serum calcium, serum iron, total protein, high sensitive C-reactive protein, serum glucose, total cholesterol, high density lipoproteins, low density lipoproteins, KT/V and PET(P>0.05). SUA levels was positively correlated with serum potassium, blood urea nitrogen and serum phosphorus(P<0.05). Conclusion Hyperuricemia was common in peritoneal dialysis patients, serum potassium levels is correlated with serum potassium, blood urea nitrogen and serum phosphorus. The timely treatment of hyperuricemia may improve the prognosis of peritoneal dialysis patients.

Objective To investigate the effects of mirror visual feedback (MVF) and modified constraint-induced movement therapy (mCIMT) on upper extremity function in post-stroke hemiplegics. Methods 117 patients with hemiplegia post-stroke were collected prospectively from December 2013 to October 2016, and randomly divided into the following four groups: group A (n=30), group B (n=29), group C (n=28) and group D (n=30). All patients were trained with conventional comprehensive rehabilitation therapy for four weeks, while the group B and group C were respectively trained with MVF and mCIMT based on conventional comprehensive rehabilitation therapy. Finally, the group D was simultaneously trained with MVF and mCIMT. The investigation duration was set as four weeks for all groups. The Fugl-Meyer Assessment (FMA) score, Upper Extremity Function Test (UEFT) score, and Modified Barthel Index (MBI) score were used as main index of clinical effects. Results After treatment, the scores of FMA, UEFT and MBI were respectively (26.37±3.44),(43.30±3.46),(56.27±4.76) in group A, (29.17±2.82), (45.41±3.40), (58.72±4.48) in group B, (29.46±3.16), (45.71±2.37), (58.82±3.89) in group C, (31.93±2.74), (48.83±3.57), (62.17±4.51) in group D.Comparing with the scores before treatment, the paired-sample t test showed that there were significant differences (P<0.05). The single factor variance test showed that the scores of the group D were significant better than those scores in group A, group B and group C (P<0.05); furthermore the scores of the group B and group C were significant better than the group A (P<0.05). However, there were no difference at those scores between the group B and group C (P＞0.05). Conclusion Based on conventional comprehensive rehabilitation, single combined with MVF or mCIMT may significantly improve the function of upper limb and activities of daily living (ADL) in post-stroke patients with hemiplegia. However, simultaneous combined with MVF and mCIMT will be more effective than the single one.

Objective To compare the clinical effects of different concentrations of ropivacaine for postoperative analgesia after cesarean section. Methods 300 cases of pregnant women undergoing cesarean section in our hospital from March 2015 to March 2016 were selected and were randomly divided into group A, group B and group C with 100 cases in each group. The patients in group A were given 0.15% ropivacaine 1.5 mg/kg, 0.20% ropivacaine 1.5 mg/kg in group B and 0.25% ropivacaine 1.5 mg/kg in group C, and at the same time all the pregnant women were given analgesic pump assisting analgesia. The pain visual analogue scales (VAS) of the pregnant women were recorded at 6 hours, 12 hours, 24 hours and 36 hours after cesarean section and the number of times of analgesia pressing pump were also recorded. The satisfaction degree of analgesic effect and the TAP occurrence of adverse reactions of the patients were also recorded. Results The VAS scores of group B and group C were lower than that of group A(P<0.05). 24 hours after cesarean section, the VAS score of group C was lower than that of group B (P<0.05). Compared with group B and C, the number of times of analgesia pressing pump in group A were more but the analgesic effect of satisfaction was lower (P<0.05), and at the same time the number of times of analgesia pressing pump in group B were more than those in group C (P<0.05). No adverse reactions were found in the three groups. Conclusion The treatment of using of 0.25% of ropivacaine for muscle block for postoperative analgesia after cesarean section is effective and safe, which may be widely used in clinical practice.

Objective To explore the application value of color Doppler ultrasound in patients with azoospermia who underwent testicular needle biopsy. Methods Retrospective analysed the clinical data of 53 cases patients with azoospermia from 2012 November to 2015 February in our department.All patients underwent routine scrotal ultrasonography, to detecte the peak systolic velocity (PSV), end diastolic velocity (EDV) and resistance index (RI) of testicular artery (TA)and intratesticular artery (ITA)with spectral Doppler ultrasound. Color Doppler ultrasound was used to observe the distribution and the number of blood vessels in the testicle, and semi quantitative score. All patients underwent testicular biopsy and Johnsen score. Results 47 patients were diagnosed as obstructive azoospermia(OA), 6 patients were diagnosed as non obstructive azoospermia(NOA). The average volume of testis was (15.3±3.6)mL in 0A group. The average volume of testis was (7.1±2.8) mL in N0A group.There was significant difference (P<0.01). The blood flow parameters(PSV, EDV, RI) results between OA group and NOA group have obvious difference,the difference was statistically significant (P<0.05). The semi quantitative classification of testicular vessels between OA group and NOA group have obvious difference,the difference was statistically significant (P< 0.01). Conclusion Color Doppler ultrasound is a good predictor of testicular spermatogenic function, can be used as the identification index of patients with OA and patients with NOA.
