HPLC fingerprint of Congrong Zonggan capsule was established in order to provide basis for quality evaluation. With acteoside as the reference, HPLC was adopted for fingerprint analysis on Congrong Zonggan capsule. The chromatographic conditions wereas follows. Waters C18 column (4.6 mm x 150 mm, 5 μm) was used, with methylalcohol-0.1% formic acid as the mobile phase for gradient elution at the flow rate of 1.0 mL x min(-1). The detection wavelength was 330 nm, and the column temperature was 30 °C. This method was highly accurate and reproducible. All of the 13 components in tested samples reached the baseline resolved peak, and 15 batches of finished products showed the similarity of above 0.95. The method was accurate and feasible and could be used as a simple and effective method to evaluate the quality of the traditional Chinese medicines.

A novel citrinin derivative, penicitrinol L (1), along with two known analogues, penidicitrinin B (2) and pennicitrinone A (3) were isolated from the marine-source fungus Penicillium citrinum. The structure of the new compound was elucidated by spectroscopic methods including one and two-dimensional NMR as well as high-resolution mass spectrometric analysis. Furthermore, compound 1 showed modest cytotoxic activity against HL-60 cell line and compound 3 showed weak cytotoxic activity against A375 cell line.

Objective To observe the therapeutic effect of single lower limb traction plus massage for the lumbosacral tunnel syndrome.Methods The selected 80 candidate patients were divided into the observation group with 38 patients and treatment group with 39 patients. The observation group received single lower limb traction plus massage and the treatment group received pelvic traction plus massage. Both groups therapy last 5 days, The Japanese orthopaedic association scores (JOA) was evaluated for subjective symptoms, signs, functional activity and bladder function score. The therapeutic effect was evaluated.Results The total effective rate (94.7% vs. 82.1%;χ2=12.160,P=0.007) in the observation group was significantly higher than that in the control group. O, The scores of JOA at one week after treatment (20.2 ± 2.0 vs. 18.3 ± 2.8;t=3.419, P<0.01) and two weeks after treatment (24.4 ± 1. 4vs. 22.6 ± 3.0;t=3.359,P<0.01) in the observation group were significantly higher than those in the control group.Conclusions The single lower limb traction plus massage can improve the clinical symptoms of patients with lumbosacral tunnel syndrome, and be superior to the pelvic traction plus massage.

Objective To investigate the feasibility and safety of laparoscopic-assisted gastrectomy for distant gastric cancer.Methods All 18 patients with distant gastric cancer receiving laparoscopic-assisted gastrectomy were analyzed.Results Laparoscopic-assisted distal gastrectomy was performed successfully in all patients.The mean operation time was(291.33?19.61) min.The mean blood loss was(151.32?71.78) ml.The mean numbers of harvested lymph node were 14.57?3.11.The mean time of gastrointestinal function recovery was(3.46?0.93) d,the mean out of bed activity time was(1.75?0.45) d.All patients were followed up for 1-24 months,mean 11 months.No local recurrence,trocar implant or distant metastasis happened.Conclusion Laparoscopic-assisted gastrectomy is a feasible and safe surgical procedure combined with minimal trauma and fast recovery.

OBJECTIVE:To establish a RP-HPLC method for simultaneous determination of chlorapheniramine maleate,furacilin and ephedrine hydrochloride in Puma nose drops.METHODS:The analysis was carried on a XDB C 8 column;the mo?bile phase was composed of methanol(A),acetonitrile(B)and0.02mol/L potassium dihydrogen phosphate solutions(containing0.2%triethylamine and adjusted to pH3.0with phosphoric acid,C)with linear gradient elution(0min~3.5min,A∶B∶C=6∶13∶18,8.5min,A∶B∶C=6∶30∶64)and the flow rate was1.0ml/min;the detection wavelength was254nm and the column temperature was30℃.Chloramphenicol was used as the internal standard.RESULTS:The linear ranges were0.04~0.20mg/ml for chlorapheniramine maleate,0.02~0.10mg/ml for furacilin,0.50~2.50mg/ml for ephedrine hydrochlo?ride.The average recoveries were99.44%(RSD=0.48%,n=3)for chlorapheniramine maleate,101.36%(RSD=0.41%,n=3)for furacilin and99.43%(RSD=0.59%,n=3)for ephedrine hydrochloride.CONCLUSION:The method is reliable,accurate and suitable for quality control of Puma nose drops.

Objective To discuss causes and corresponding prevention for groin pain occurred early after total hip arthroplasty(THA).Methods A retrospective study was done on 189 cases(193 hips)treated with THA including unilateral procedures in 185 hips and bilateral procedures in eight hips to analyze common causes for early groin pain.Results Groin pain was found in 9.3% hips(18/ 193)during hospital stay,including 1.6%(3 cases)with deep infection,1.6%(3 cases)with incision infection,1%(2 cases)with posterior dislocation,4.1%(8 cases)with leg lengthening and 1%(2 cases)with hematoma.Conclusions Despite of the numerous diagnostic alternatives available to the orthopedic surgeon,detailed history,careful physical examination,necessary laboratory and imaging stud- ies can contribute to a correct determination of causes for groin pain.Meanwhile,appropriate indication, accurate preoperative radiographic measurement,intraoperative standardized surgical procedures and per- fect rehabilitation are necessary to avoid complications.
