OBJECTIVE: To analyze the factors of intracranial infection after transnasal endoscopic crannialbase approach. METHOD: Retrospective analysis of 346 patients of ransnasal endoscopic crannialbase approach, logistic regression analysis of the factors was carried out. RESULT: The total number of cases of postoperative infections were 19 cases in 346 patients, the infection rate was 5.49%. The cerebrospinal fluid rhinorrhea , the restitution of skull base, the history of crannialbase approach, the history of radiotherapy and diabetes were infection fators after transnasal endoscopic diabetes (P < 0.05), while sex,age,operative approach,the use of artificial material,longer application of antibiotics before or after operation,and the history of chemotherapy had no obvious effects (P > 0.05). CONCLUSION Intracranial infection after transnasal endoscopic the use of artificial material was affected by many factors. Much attention should be paid for the intracranial infection prevention.

As a common and frequently-occurring disease,glenohumeral instability is become one of disease which restrict upper limb activity. The diagnosis of this disease is easy, but it is very difficult to assess the degree of periarticular soft tissue injuries. With the development of magnetic resonance imaging and arthroscopy, MRA become the gold standard for evaluation of glenoid labrum, joint capsule and ligaments injury. The traditional manual reduction is a fast, simple method, but often can cause adverse consequences,such as rotator cuff tear,ligament relaxation,and habitual dislocation. Open operation can rebuild stability of joint,but with many new treatment methods,especially the arthroscopic reconstruction has gradually replaced the open operation, and become the mainstream trend, but for the long-term effect of capsular tightening surgery, rotator cuff gap closure is not clear,it is need further follow-up observation.

Objective To study the clinicopathological features of C3 glomerulonephritis and the associations between plasma complement fragments level and clinical manifestations.Methods The clinical and pathological data of the 12 patients with C3 glomerulonephritis in our division from January 1999 to June 2010 were analyzed retrospectively.Concentrations of plasma factor B,Ba,C3,C3a,C4a and C5a were detected by commercial available sandwich ELISA kits on the day of renal biopsy.Results Ten of the 12 patients were C3 glomerulonephritis without MPGN,and the rest 2 were C3 glomerulonephritis with MPGN.All the patients presented proteinuria.Two of the 10 C3 glomerulonephritis patients without MPGN presented nephrotic range proteinuria,6 with microhematuria,1 with gross hematuria,and 2 with renal insufficiency.One of the 2 C3 glomerulonephritis patients with MPGN presented nephrotic range proteinuria,accompanied by microhematuria,hypertension and renal insufficiency.The other patient showed moderate proteinuria with normal renal function.Most of C3 glomerulonephritis patients without MPGN showed mild mesangial proliferative glomerulonephritis,and 4/10 patients had various degree cresentic formation.One C3 glomerulonephritis patient with MPGN had 47.1％ cresentic formation.The concentration of plasma C3 in C3 glomerulonephritis patients was normal,while the plasma factor B was significantly decreased,and the concentrations of plasma Ba,C3a,C4a and C5a were significantly elevated.The concentration of plasma Ba was positively correlated with the proteinuria level,while the concentrations of plasma C3a,C4a and C5a were not correlated with the levels of proteinuria or plasma creatinine.Conclusions Majority of these 12 patients were C3 glomerulonephritis without MPGN,manifests as nephritic syndrome clinically and mild mesangial proliferative glomerulonephritis histopathologically.Complement activation via alternative pathway may play an important role in the pathogenesis of C3 glomerulonephritis.

Acetylation regulated by histone deacetylases (HDAC) has a broad influence on plenty of physiological processes and regulation of malignant tumor.HDAC inhibitors can promote tumor cell apoptosis and have little effect on normal cells,so they have been developed a new kind of anti-tumor agent,and part of them have entered clinical trials.Vorinostat and romidepsin have been approved by FDA for treating cutaneous T cell lymphoma patients with progressive,persistent and recurrent disease.Studies of the molecular mechanisms of the HDAC inhibitors will contribute to the further clinical application.

Objective To explore the distribution of alkane, alcohol and ketone in indoor air of some apartments in Hangzhou. Methods 55 air samples were randomly collected from 31 apartments in Hangzhou by Carbotrap 300 air-sampling tube, during October-December, 2002, and April-May, 2003, then the volatile organic compounds in air samples were determined by heat-desorption GC-MS. Results 41 kinds of alkane, 11 kinds of alcohol and 9 kinds of ketone were found in air samples collected from 31 apartments in Hangzhou, average concentration of total alkane was 24.096 7 ?g/m3, average concentration of total alcohol was 3.670 7 ?g/m3, and average concentration of total ketone was 33.492 4 ?g/m3 respectively. The dominant indoor air pollutants were hexane, heptane, octane, nonane, decane, undecane, dimethylbutane, methylhexane, n-butanol, cyclohexanone, propanone, 2-butanone. The concentrations of alkane, alcohol and ketone in indoor air of apartments decreased with the time went on after the house decoration finished on the whole. 10 of 14 alkanes showed positive correlation to the temperature, 6 of them to the relative humidity at the sampling points. 2 of 11 alcohols and 3 of 9 ketones showed positive correlation to the relative humidity at sampling points. Conclusion The increasing temperature is the important factor for the release of alkanes in indoor air. The increasing relative humidity is the influence factor for the release of alcohols, ketones, and some alkanes in indoor air.

Objective To evaluate the diagnostic value of hysteroscopy in comparison with hysteros- alpingography(HSG) in the detection of intrauterine abnormalities in infertile patients.Methods 52 patients(ob- serving group) with filling defects under HSG received hysteroscopy,and the remaining 22 patients (contrasting group) with normal hysterosalpingographic findings also received hysteroscopy with their consent.Results In- trauterine abnormalities in observing group and contrasting group confirmed by hysteroscopy were 78.8 % and 9.1% respectively,and there was statistical significance(P

Objective To study the nosocomial infection in the patients with systemic lupus erythematosus (SLE). Methods A prospective survey of nosocomial infection in 456 cases with SLE was carried out for 84 months.Result Incidence of nosocomial infection in patients with SLE was 36 4%,infection of respiratory tract accounted for 45 2%,infection rates in urinary tract,skin and other regions were 16 0%,12 6% and 26 2% respectively.Gram negative bacilli were the predominant pathogens and the pathogens had higher frequency of multiple antibiotic resistance. Conclusion The factors related to nosocomial infection were the use of broadspectrum antibiotics,prednisone and administration of immunosuppressant,etc.
