Objective To assess the value of video-assisted thoracoscopic mini-invasive lobectomy in the treatment of pulmonary benign lesions or malignancies. Methods A retrospectively analysis on clinical data of 35 cases of video-assisted thoracoscopic mini-invasive lobectomy, which were performed from February 2002 to June 2006, was made. The pathological diagnosis included 31 cases of peripheral lung cancer (T_1N_0-1M_0), 3 cases of bronchiectasis, and 1 case of atelectasis combined with pulmonary abscess. The procedures included 30 cases of anatomical lobectomy and 5 cases of non-anatomical lobectomy. Results No conversion to open surgery was required. The operation time was 85~210 min (115?35 min) and the intraoperative blood loss was 150~450 ml (210?55 ml). Postoperatively, acute respiratory failure was encountered in 2 cases, and mechanical ventilation was given for 3 and 5 days, respectively. Acute myocardial infarction occurred in 1 case, which was cured by early-stage thrombolysis. No postoperative complications were seen in the remaining 32 cases. The closed chest drainage was maintained for 2~10 days (mean, 5.4 days). In 3 cases of pulmonary benign lesions, follow-up checkups for 41, 33, and 13 months, respectively, found no long-term complications. In 25 cases of lung cancer, follow-up observations were made for 3~53 months (mean, 15.2 months), including 3~12 month in 6 cases, 12~24 months in 9 cases, 24~36 months in 7 cases, and 36~53 months in 3 cases. There were 4 cases of death due to cancer recurrence or metastasis (16%), 2 cases of with-tumor survival (8%), and 19 cases of disease-free survival (76%), respectively. Conclusions Video-assisted thoracoscopic mini-invasive lobectomy is a feasible and safe procedure for peripheral lung cancer and benign lung diseases.

Objective To investigate operative method for preventing and treatment intestinal obstruction due to relapse adhesion.Methods Sixty patients with recurrent adhesive ileus treated by surgery were randomized into two groups,that was intra-enteropexy group and extra-enteropaxy group.Twenty-three patients in intra-enteropexy group were treated by retrograde intra-enteropaxy through appendix stump.Thirty-seven patients in the extra-enteropexy group were treated by Noble procedure.The effect and complication were compared.Results In the intra-enteropexy group,2 cases (8.70%) were complicated with incision infection,1 case was died (4.35%) and there was no relapsed,abdominal spastic pain and incomplete intestinal obstruction occurred.In the extra-enteropexy group,3 cases (8.11%) were complicated with incision infection,3 cases were died (8.11%),abdominal spastic pain were occurred in 11 cases (29.73%),incomplete intestinal obstruction were occurred in 6 cases(16.22%),and there were 3 cases run into relapse.Conclusion The retrograde intra-enteropexy through appendix stump is an effective method for preventing and treatment to adhesive ileus.

Object To study the chemical constituents of the whole plant of Selaginella stauntoniana Spring. Methods Various chromatographic techniques were employed for the isolation and purification of its constituents, and structurally identified by spectral analysis (IR, UV, MS, 1HNMR, 13CNMR) and chemical evidence. Results Four compounds were identified from its extract as: emodin (Ⅰ), ginkgetin (Ⅱ), hinokiflavone (Ⅲ), amentoflavone (Ⅳ). Conclusion All the compounds were isolated in this plant for the first time; compound Ⅰ was found from the plants of Selaginellaceae Beauv. for the first time.

OBJECTIVETo study the effect of multiglycosides of Tripterygium wilfordii (GTW) on sperm apoptosis in male rats and its possible mechanisms.

METHODSSixteen male SD rats were equally assigned to two groups to receive GTW and carboxymethylcellulose (CMC) intragastrically, both at 20 mg/(kg x d) for 6 weeks. Then the epididymal sperm was collected for the measurement of the apoptosis rate, sperm membrane lipid fluidity and the contents of NO, MDA and SOD by flow cytometry and spectrophotometric determination.

RESULTSAfter 6 weeks of medication, the GTW group showed a significant increase in sperm apoptosis and contents of NO and MDA (P < 0.01) and a remarkable decrease in sperm membrane lipid fluidity (P < 0.05) and SOD content (P < 0.01) as compared with the CMC control group.

CONCLUSIONGTW can damage sperm membrane lipid peroxidation and sperm membrane structure, increase sperm apoptosis, and reduce sperm membrane lipid fluidity.

OBJECTIVE：To compare the quality between Stamen typhae and pollen of T. angustifolia ，and provide scientific evidence for the improvement of quality standard of T. angustifolia . METHODS ：Fifteen batches of S. typhae were collected. Pollen minus sieve ，impurity plus sieve （filament and anther ）were sift out from S. typhae according to the identification method of T. angustifolia in Chinese Pharmacopoeia （2015 edition）. The characteristics and components of S. typhae and pollen ，filament and anther of T. angustifolia were comfirmed by impurity ， character examination and microscope ， TLC. The contents of isorhamnetin-3-O-neohesperidoside and typhaneoside in S. typhae and pollen ，impurities plus sieve （filament and anther ）of T. angustifolia were determined by HPLC. RESULTS ：S. typhae was a mixture of pollen ，anther and filament of T. angustifolia ，in the form of brownish yellow flocculent. The pollen of S. typhae was yellow powder with delicate hand feel ，slight smell and light taste；the surface of cells was slightly striped. The filaments and anthers were filiform and short-term ，rough and astringent ，and the cell surface were long strip. TLC chromatogram of S. typhae ，pollen and impurity of T. angustifolia had the same color spots at the same location. The contents of isorhamnetin- 3-O-neohesperidoside，typhaneoside and their aggregate were the highest in pollen （0.42％，0.24％，0.64％）；the second in S. typhae （0.22％，0.17％，0.39％）；the lowest in the impurities plus sieve （0.19％， 0.14％，0.33％）. The total contents of isorhamnetin- 3-O-neohesperidoside and typhaneoside in S. typhae and in impurities plus sieve did not reach the content limit stipulated in Chinese Pharmacopoeia （not less than 0.50％）. CONCLUSIONS：The medicinal components of T. angustifolia mainly exist in pollen. It is suggested that S. typhae should be used as the raw material to obtain pollen，and should not be used directly.

OBJECTIVE: To investigate the early effectiveness of transiliac-transsacral screws internal fixation assisted by augmented reality navigation system HoloSight (hereinafter referred to as "computer navigation system") in the treatment of posterior pelvic ring injuries. METHODS: A retrospective analysis was made in the 41 patients with posterior pelvic ring injuries who had been treated surgically with transiliac-transsacral screws between June 2022 and June 2023. The patients were divided into navigation group (18 cases, using computer navigation system to assist screw implantation) and freehand group (23 cases, using C-arm X-ray fluoroscopy to guide screw implantation) according to the different methods of transiliac-transsacral screws placement. There was no significant difference in gender, age, body mass index, causes of injuries, Tile classification of pelvic fracture, days from injury to operation, usage of unlocking closed reduction technique between the two groups ( P>0.05). The time of screw implantation, the fluoroscopy times, the guide wire adjustment times of each screw, and the incidence of complications were recorded and compared between the two groups. The position of the transiliac-transsacral screw was scanned by CT within 2 days after operation, and the position of the screw was classified according to Gras standard. RESULTS: The operation was successfully completed in both groups. The time of screw implantation, the fluoroscopy times, and the guide wire adjustment times of each screw in the navigation group were significantly less than those in the freehand group ( P<0.05). There were 2 cases of incision infection in the freehand group, and the incision healed by first intention after active dressing change; there was no screw-related complication in the navigation group during operation and early period after operation; the difference in incidence of complications between the two groups (8.7% vs. 0) was not significant ( P=0.495). According to the Gras standard, the screw position of the navigation group was significantly better than that of the freehand group ( P<0.05). CONCLUSION Compared with the traditional freehand method, the computer navigation system assisted transiliac-transsacral screws internal fixation in the treatment of posterior pelvic ring injuries has advantages of improving the accuracy of screw implantation and reducing radiation damage and the time of screw implantation.
