Objective To establish a convenient, fast, economic and hypersensitive low-density DNA array method to detect the genotypes of human papillomavirus (HPV) and evaluate its application in clinic services.Methods HPV in cervical swab samples from 355 suspected female patients collected in gynaecology and obstetrics clinic were genotyped by hybrid capture (HC) II method and low-density DNA array simultaneously. HPV in 730 clinic samples from the area of Pearl River delta were genotyped by low-density DNA array.Results Among 355 suspected samples positive HPV-DNA were detectable in 211 (59.4%) samples by DNA array and 222 (62.5%) samples by HCII method. The concordance rate between the two assays was 94.1%. In the HPV genotypes 15 high-risk type and 5 low-risk type were detected by low-density DNA array. The most common high-risk types were HPV-16, 52, 58 and 56. The peak age of HPV infection was 26-30 years. The distribution of genotypes was different from various degree of cervical changes.Conclusion Either single type or multiple type of HPV infection can be detected by low-density DNA array. The combination of HPV detection with cytology detection will provide instruction for cervical cancer screening.

OBJECTIVE: To explore the relationship between the expression changes of cytokines, interleukin-6 (IL-6), interleukin-8(IL-8), and tumor necrosis factor-alpha (TNF-alpha), and the wound time following explosive injury to rabbit's chest. METHODS: The rabbit's model of explosive injury was established. The expression levels of IL-6, IL-8 and TNF-alpha in the plasma were detected by ELISA method at different wound time (0.5-12h). RESULTS: The level of IL-6 increased at 3h after wounding and reached peak at 6 h. The level of IL-8 increased at 1 h and reached peak at 6 h. The level of TNF-alpha increased at 0.5 h and reached peak at 3 h. CONCLUSION IL-6, IL-8 and TNF-alpha have a time-related expression after explosive injury.

OBJECTIVETo explore causes of shoulder pain and propose prevention measures in treating acromioclavicular joint dislocation.

METHODSFrom January 2005 to January 2013, 86 patients with acromioclavicular joint dislocation (Tossy III) were treated with hook plate fixation, and were divided into two groups. Bsaed on recovery of shoulder function mostly, the patients who suffered from rest pain, motion pain were named as shoulder pain group, while the patients without pain were named as painless group. In shoulder pain group, there were 21 cases including 15 males and and 6 females ranging the age from 22 to 62 years old with an average of (40.6±11.2) years old. There were 8 cases were on the left side and 13 cases were on the right side. In painless group, there were 65 cases including 36 males and and 29 females ranging the age from 19 to 65 years old with an average of (40.0±11.3) years old. There were 33 cases were on the left side and 32 cases were on the right side. The time from injury to operation ranged from 3 h to 8 d with an average of 34.6 h. Shoulder function of all patients were normal before injuried. Postoperative pain, activity of daily living (ADL), range of motion, deltoid muscle strength were compared. Anteflexion,rear protraction, abduction and upthrow of shoulder joint were also compared. Postoperative complications between two groups were observed and compared.

RESULTSAll patients were followed up from 12 to 48 months with an average of 18.5 months. Constant-Murley score were used to evaluate clinical efficacy at the least following up, and 13 cases got an excellent results, 5 moderate, 2 good and 1 poor in shoulder pain group ; while 61 cases were obtained excellent results, 3 moderate and 1 good in painless group. There were significantly differences between two groups in Constant-Murley score and activity of shoulder joint (P<0.05). In shoulder pain group, 3 cases were disconnected, 1 case occurred stress fracture, 9 cases were subacromial impingement syndrome, 5 cases occurred subluxation, 1 case occurred plate breakage and 11 cases were acromioclavicular arthritis.

CONCLUSIONChosing individual clavicular hook plate, fulfilling anatomic reset, paying attention to the repair of articular capsule ligament, and reducing hook and bone antagonism between stress is the key point of preventing and decreasing postoperative shoulder pain.

Objective To analyze the electrocardiography(ECG)data of pressure overload-induced cardiac hy pertrophy rats.Methods Pressure overload cardiac hypertrophy was induced by abdominal aorta constriction. Echocardiogram and heart weight measurement demonstrated the occurrence of cardiac hypertrophy.Standardized ECG parameters of limb and chest were measured and statistically analyzed.Results Two weeks after hypertrophy models were established,echocardiogram showed greater LVPWTd,IVSTd,LVDd.ECG showed that left axis deviation and higher R waves in V_A,V_B,V_C(P

Population pharmacokinetics of vancomycin (VAN) in the Chinese patients was described by using nonlinear mixed-effects modeling (NONMEM). 619 VAN serum concentrations data from 260 patients including 177 males and 83 females were collected separately from two centers. A one-compartment model was used to describe this sparse data. No significant difference was observed between two center datasets by introducing SID covariate. The final model was as CL= (θ (base0+ θ(max) x(1 -e(-θ(Age)(Age/72) and V = θ x θ (Age)(Age/72). The creatinine clearance (CL(Cr)) and Age were identified as the most significant covariate in the final model. Typical values of clearance (CL) and volume of distribution (V) in the final model were 2.91 L x h(-1) and 54.76 L, respectively. Internal model validation by Bootstrap and NPDE were performed to evaluate the robustness and prediction of the final model. The median and 95% confidence intervals for the final model parameters were based on 1000 Bootstraps. External model evaluation was conducted using an independent dataset that consisted of 34 patients to predict model performance. Pharmacodynamic assessment for VAN by AUC (0-24 h) to MIC ratios of over 400 was considered to be the best to predict treatment outcomes for patients. AUC (0-24 h) was calculated by clearance based on the above population model. The results indicate that the conventional dosing regimen probably being suboptimal concentrations in aged patients. The approach via population pharmacokinetic of VAN combined with the relationship of MIC, Age, CL(Cr) and AUC(0-24 h)/MIC can predict the rational dose for attaining efficacy.
