OBJECTIVETo investigate the short-term clinical outcome of unicompartmental knee arthroplasty for the treatment of spontaneous osteonecrosis of the knee.

METHODSFrom September 2013 to April 2014,5 patients with spontaneous osteonecrosis of the knee underwent unicompartmental knee arthroplasty, included 3 males and 2 females, aged from 65 to 80 years old with an average of 74 years. The courses of disease was from 1 to 6 years with the mean of 3 years. According to the radiographic staging criteria of Koshino, 1 case was stage II, 2 cases were stage III, 2 cases were stage IV. Clinical effects were assessed by VAS score, HSS score, and knee range of motion, tibiofemoral angle before and after operation.

RESULTSAll the patients were followed up from 6 to 7 months with an average of 6.4 months. All incisions obtained primary healing, and there were no complications such as infection, thrombosis, fracture of lower limbs. All 5 patients' pain relieved and their knee function improved significantly after operation, but knee range of motion had no obviously improved. Postoperative HSS scores, VAS scores, tibiofemoral angle were significantly improved than that of preoperative.

CONCLUSIONThe short-term effect of unicompartmental knee arthroplasty in treating spontaneous osteonecrosis of the knee is satisfactory.

Objective To study on the value and safety of early endoscopic retrograde cholangiopan-creatography (ERCP)and endoscopic sphincterotomy (EST) in acute biliary pancreatitis. Methods Ninety-two patients with acute biliary pancreatitis underwent early ERCP (within 72 hours) and received endoscopic therapy (ERCP group). Another 40 patients with acute biliary pancreatitis were treated conservatively without ERCP (control group). The disappearance of abdominal pain, decrease of serum amylase level, the mean days and costs of hospitalization and complications were observed in all patients. Results In ERCP group, all patients were performed EST, stones in 72 choledocholithiasis patients had been removed with net-basket or air pocket. Ten cases of severe acute biliary pancreatitis received endoscopic pancreatic duct stents drainage. Ninety two cases of acute biliary pancreatitis received endoscopic nasal catheter bile drainage. The days of the disappearance of abdominal pain, the decrease of serum amylase levels, the cost of the hospitalization and the days of the hospitalization were significantly shorter in the early ERCP group than in the control group. The mortalities in ERCP and control group were 8. 3% and 33. 3% respectively. Conclusion Early ERCP endoscopic therapy is a safe procedure has the superiorities in lowering the mortality, hospital days and expense.

Objective To evaluate the therapeutic effects of somatostatin(stilamin)and rhubarb for severe acute pancreatitis(SAP).Method A total of 42 patients with SAP received traditional treatment in combination with somatostatin(stilamin)and rhubarb,and compared with 40 SAP patients with routine treatment.The changes of acute physiology and chronic health evaluationⅡ(APACHEⅡ),serum amylas,serum creatinine,blood calcium,blood glucose,white blood cell count,the duration of abdominal pain,abdominal bulge,fast and hospital stay,complications,morlality and operation rate on the fist day,third day and fifth day were compared between two groups.Results Somatostatin and rhubarb reduced the complications,operation rate and mortality, and shortened the duration of abdominal pain,abdominal bulge,fast and hospital stay.Conclusions Combination of somatostatin and rhubarb is effective in the treatment of SAP patients.

Objective To investigate predisposing factors for early infection in patients with severe acute pancreatitis.Methods The clinical and laboratory data including age、gender、APACHE Ⅱscore on admission、hemodiastase、mechanical ventilation、blood calcium、mean arterial blood pressure、blood glucose、 alanine aminotransferase、aspartate aminotransferase、total bilirubin、necrosis of the pancreas、hypoxemia、 entero-functional disturbance、etiological factor、serum albumin、serum creatinine、urea nitrogen and haematocrit were analyzed by multiple linear regression in relation with the infection incidence in the 86 SAP patients hospitalized from Jan 2002 to Mar 2007.Results The fasting time、hiliary panereatitis、 hypoxemia、necrosis of pancreas、entero-functional disturbance、serum creatinine、urea nitrogen and haematocrit were positively correlated with the incidence of pancreatic infection(all P

Objective To investigate the features of chronic prostatitis during puberty(CPP)and the effects of pelvic floor biofeedback therapy.Methods Totally,25 CPP children (mean age,16 years) and 15 children (mean age,16 years) with normal lower urinary tract as controls were included.In CPP group,NIH-CPSI scores were evaluated,expressed prostatic secretions (EPS) were examined,and bacterial culture was done;and CPP patients were categorized based on the definitions of NIH types.In both groups, urodynamic examination was performed,including evaluation of uroflow curve,maximum flow rate (Q_(max)), post-voiding residual urine (PVR),detrusor-sphincter dyssynergia (DSD),maximum detrusor pressure (P_(det,max))and maximum urethral closure pressure (MUCP).CPP patients underwent biofeedback therapy, and 10 weeks later the effects were assessed.Results In CPP group,NIH typing showedⅡ,ⅢA andⅢB in 1,3 and 21 cases,respectively.Before treatment in CPP and control groups,the incidence of staccato voiding (20 cases vs 1 case),DSD (22 cases vs 1 case),Q_(max)(10.7?3.7 vs 15.0?4.3ml/s),PVR (7.7?4.1vs 3.2?2.6ml),P_(det,max)(115.1?33.6vs 76.8?16.6cm H_2O)and MUCP(176.5?45.7 vs 86.2?28.5cm H_2O)all showed significant differences between the 2 groups(P＜0.05).In CPP group,the differences in pain(4.6?2.2 vs 2.1?1.6),urination (7.9?2.0vs 2.2?1.7),life impact (9.4?2.2vs 2.6?2.1)and total scores(22.0?5.2vs 7.0?4.2) of NIH-CPSI and Q_(max)(10.7?3.7 vs 14.9?5.6) between pre-and post-biofeedback were significant (P＜0.05).Conclusions The main type of CPP is categoryⅢB.The primary symptom is voiding disorder,which leads to greater psychological stress in patients.Children with CPP have pelvic floor dysfunctions and multiple abnormal urodynamic param- eters.The short-term effect of biofeedback strategies for CPP is satisfactory.

OBJECTIVETo explore the relationship between angiotensin converting enzyme (ACE) gene single nucleotide polymorphisms (SNP) and premature coronary heart disease (PCHD) patients with blood stasis syndrome (BSS).

METHODSrs4343, rs4293, and rs4267385 were selected at SNP from ACE gene. Allele and genotype were detected. Frequencies of allele and genotype were compared by using time-of-flight mass spectrometry technique (TOF-MS).

RESULTSCompared with the healthy control group, genotype of rs4293 and rs4267385 in ACE gene were similar, but there was statistical difference in polymorphisms and allele frequencies of rs4343 in the I and II group (P < 0.05, P < 0.01). The frequency of G allele was higher in the 3 groups than in the healthy control group (P < 0.05, P < 0.01). The relative risk analysis showed that the risk for PCHD occurrence in G allele carriers at rs4343 (GG +AG) was 3. 6 times the risk in non-G allele carriers (95% CI: 1.224-10.585, P = 0.02). There was also statistical difference in sex, age, TC, and TG after adjusted Logistic regression analysis (OR = 3.994, 95% CI: 1.230-12.974, P = 0.021).

CONCLUSIONThe polymorphism at rs4343 (G2350A) might be one of risk factors for PCHD occurrence, but not a predisposing factor for PCHD patients of BSS.

OBJECTIVETo investigate the relationship between cardiac Cerebrovascular disease and serum uric acid(SUA) in the coastal inhabitant, and try to provide base for prevention of the local metabolic disease and cardiac Cerebrovascular disease.

METHODWe got 3111 local people who had participated in the annual physical examination in the perch hospital for the research on the level of SUA and the relative risk factor. According to SUA level we divided the cases into two groups. One is hyperuricemia group and the other is control group.

RESULTS(1)The average SUA level was (380.2-/+62.58) micromol/L in the males, while (290.82-/+60.32) micromlo/L in the female. The sick rate of hyperuricaemia rate, was 21.8% for male, and the 17.6% of female. This disease affected more men than women. It has significant difference (P<0.01); (2)The SUA level of the showed a positive correlation with the indexes of the total cholesterol, the triglyceride, the blood pressure and the body weight index. The SUA level in overweight/obesity people was obviously higher than that of the normal weight people.

CONCLUSIONS(1)The sick rate of hyperuricaemia is high in Zhongshan coastal area, which due to many related factors. As far as, few people know it, so we should adopt the synthesis measure to prevent and control it to reduce the sick rate; (2)the rise of The SUA level possibly becomes one of the independent dangerous and predictive factor for the heart cerebral von disease.

Objective To investigate the expression of neural-nitric oxide synthase (nNOS) in renal clear cell carcinoma and its clinical significance.Methods The expression of nNOS mRNA in 533 samples of TCGA database was analyzed with Student t test,and statistical analysis was performed to assess the relationship between nNOS expression and clinical prognosis with Kapla-Meier test.Western blot analysis of nNOS protein expression in 10 cases of clear cell renal cell carcinoma(ccRCC) from department of urology of Wuhan union hospital with student t test.Results The mRNA levels of nNOS in 72 cases of ccRCC in tumor tissues and adjacent tissues and were 2.99 ± 0.28 and-1.57 ± 0.17,it is significantly lower than those in adjacent tissues (P ＜ 0.01).The mRNA levels of nNOS in 533 cases of ccRCC,in tumor tissues and adjacent tissues and were 2.99 ± 0.28 and-1.76 ± 0.05,it is significantly lower than those in adjacent tissues (P ＜ 0.01).A total of 533 sample studies showed a low correlation between nNOS expression and clinical T stage,T1-1.59 ±0.08,T2-1.96 ±0.13,T3-1.90 ±0.09,T4-2.38 ±0.28 (P =0.0029) and -1.63 ±0.06 and-2.16 ± 0.13 between non-metastasis and no-metastasis (P =0.0009),and-1.57 ± 0.08 and-2.03 ± 0.11 between non-recurrence and recurrence (P =0.008).Survival analysis showed that the overall survival time were (40.3 ± 5.6) months and (48.3 ± 5.7) months in lower and higher nNOS expression,and disease free survival time were (37.1 ± 2.1) months and (40.3 ± 5.6) months in lower and higher nNOS expression,both with shorter time in low expression of nNOS (P ＜ 0.01).nNOS proteins were 1.02 ± 0.16 and 0.61 ± 0.1 1 in tumor tissues and adjacent tissues with significantly lower expression(P＜0.05).Conclusions The mRNA and protein of nNOS are lower in ccRCC with a poor prognosis of ccRCC.

OBJECTIVEPericardial effusion (PE) is a major complication of atrial fibrillation ablation (AFB). We analyzed the incidence, risk factors and managements of PE post AFB (radiofrequency catheter ablation).

METHODSA total of 156 consecutive patients with AF [male 108, paroxysmal AF 114, (57.6 +/- 11.3) years], who underwent AFB guided by a three-dimensional mapping system (CARTO or CARTO-Merge, Biosense-Webster Inc., Diamond Bar, California) and a circular mapping catheter (Lasso, Biosense-Webster Inc., Diamond Bar, California), were included in this study. The ablation strategy included circumferential pulmonary veins isolation (CPVI), linear ablation and/or complex fractionated atrial electrograms (CFAEs) ablation. Electrophysiological data and vital signs of patients were recorded by a multiple physiological recorder (Prucka, GE Medical Systems) during ablation. Ablation process, sites, duration and other related factors were also recorded. Echocardiography and other examinations were performed for diagnosing and monitoring PE.

RESULTSCPVI were achieved in all 156 patients. Incidence of PE was 10.3% (16/156) post AFB. One patient developed acute cardiac tamponade and emergency drainage of the pericardial effusion was performed through a median sternotomy and patient recovered without complications during the 18 months follow-up. The rest 15 PE patients with small PE received outpatient care and no invasive treatment was needed and PE disappeared after 3 months in 6 patients and after 6 months in 9 patients. Univariate analysis showed that the composition of gender (P < 0.01), ablation in coronary sinus (CS, P = 0.026), ablation of CFAEs (P = 0.037) and superior vena cava (SVC, P = 0.041) were risk factors for PE. Logistic regression analysis showed that female gender [beta = 3.594, exp (b) = 36.4, 95% confidence interval (CI): 4.2 - 312.1, P = 0.001] and ablation in CS [beta = 2.419, exp (b) = 11.2, 95% CI: 1.0 - 124.6, P = 0.049] were independent risk factors for PE post AFB.

CONCLUSIONSPE is a common complication of AFB, female gender and ablation in CS were independent risk factors for PE. Most PE patients experienced spontaneous recovery but emergency treatment was needed for patient with cardiac tamponade.
