Objective To compare the safety and effects of retroperitoneal laparoscopic ureterolithotomy(RLU)and microinva-sive percutaneous nephrolithotomy with lithotomy (MPCNL)for treating complicated upper ureteral calculi and to explore the sur-gical indications and the technical key points.Methods The clinical data in 54 cases of complicated upper ureteral calculi from Mar. 2009 to Sep.2012 were retrospectively analyzed,31 cases adopted the MPCNL therapy (MPCNL group)and 23 cases received the RLU therapy(RLU group).The perioperative complications and the stone clearance rate were compared between the two groups. Results The mean operating time was (69.70±7.73)min in the RLU group and (46.50±7.09)min in the MPCNL group(t=-11.436,P=0.000);the intraoperative blood loss was (21.50±7.23)mL in the RLU group and (66.90±20.00)mL in the MPC-NL group(t=9.94,P=0.000),the MPCNL group was significantly higher than the RLU group;no statistically significant differ-ences were found in the occurrence rate of postoperative hyperpyrexia,the stone clearance rate,the occurrence rate of urinary leak-age and the length of hospital stay between the two groups.Conclusion Both MPCNL and RLU have high safety and satisfactory effects for treating complicated upper ureteral calculi.RLU has less intraoperative blood loss and long operation time.

Objective To acknowledge the present status of clinical use of nonsteroidal antiinflammatory drugs(NSAIDs) in China. Methods Five hundred and seventy-five valid questionnaires were collected from 50 hospitals in different areas of China including Shanghai, Beijing, Tianjin, Shenyang and Guangzhou. Results 54.7% of doctors used cyclooxygenase-2 (COX-2) selective inhibitors. The ratio of the doctors prescribing loxoprofen, diclofenac, meloxicam were 22.6%, 23.3%, 14.60%, respectively. The ratio of the doctors who prescribe uncoated routine-dose aspirin, uncoated low-dose aspirin, enteric-coated routine-dose aspirin, enteric-coated low-dose aspirin and others were 17.0%, 14.7%, 36.8%, 28.5% and 3.0%, respectively. The ratio of doctors who only "some-times" prescribed co-medicine to prevent gastrointestinal damages when they prescribed aspirin, conventional NSAID and COX-2 selective inhibitors were 41.10%, 40.70% and 45.1%, respectively, while the most commomly used co-medicine were H2 receptor antagonist (H2 RA) and proton pump inhibitor respectively. 37.1% of doctors examined H. pylori infection status, and 76.3% of doctors would eradicate H. pylori if positive. Conclusions The most commonly used conventional NSAID is diclofe-nac. The most commonly used formulation of aspirin is enteric-coated aspirin. Most doctors only "sometimes" prescribe co-medicine together with aspirin, conventional NSAID and COX-2 selective inhibitors to prevent gastrointestinal damages, and the most commonly used co-medicine is acid inhibitor. Only a few doctors examine H. pylori infection prior to the administration of NSAID.

Neuropathy pain, or neuropathic pain (NP), which pathogenesis is complex and is lack of effective treatment, is one of common chronic pain in clinic. Studies of traditional Chinese medicine (TCM) in treating NP were increased in recent years. In the review, studies of treatments of TCM compound and monomer in NP during last decade were collected and analyzed to find out possible mechanisms, and some existing problems.

Objective To approach the value of CT double windows technique in the location of lung X-ray knife.Methods The varying window width(W),window center(C) of peripheral type carcinoma of lung and their error were deltermined.The best double window was chosen and the clinical matherial was analysed.Results (1)The biggest error among different widow widths measuring foci was 7 mm.(2)The best double windows in the location of lung X-ray knife were W1 120~180,C1-700,W2 350,C2 15.(3)34 cases of lung carcinoma were observed with double windows,the outline of foci was contiuous and clear in the 15 cases of peripheral type carcinoma of lung and 8 cases of central type carcinoma of lung without hilum infiltration(67.6%),the inner outline of foci was disappear but could be remedied by mediastinum window in 11 cases of central type carcinoma of lung with hilum infiltration. Conclusion The double widows technique is provied with accuracy and without lack fidelity,and could reflect more condition of peritumour infiltration,it is clear superior to single display technique.

Objective To study the effect of thoraco-tumba fracture with pedicle scre system. Methods Forty-two cases with thorac-lumbar fractute treated with pedicle scre system were reviewed,their clinical featuers,x-ray and CT images before and after operation were analyzed. Results With follow-up of two months to three years after operntion,height of vertebra was completely restored on thirty-four cases,neurological function recovered in various degree according to the Frankel criteria in all cases. Conclusion Pedicle scre system is an effective method for treatment of thoraco-tumbar fracture.

Objective The insulin pathways within ovary are in close relationship with female reproductive ability .The arti-cle was to observe the effects of ovarian insulin resistance on ovarian function and the effects of cryptotanshinone (CRY) on ovarian in-sulin resistance. Methods All mice were randomly divided into saline group (isotonic saline), DEX a group (isotonic saline plus DEX), CRY a group(isotonic saline plus DEX plus cryptotanshinone ), 10 in each group.The degree of insulin resistance was tested on each rat, along with the measurement of disintergrations per minute (DPM), ovulation rate and serum hormone level .After 20 fe-male mice were put to death , their ovaries were randomly divided into 4 groups:blank control group ( blank culture solution ) , DEX b group (DEX), CRY b group(DEX plus cryptotanshinone ), and WT group (DEX plus cryptotanshinone plus wortmannin ), 8 in each group. Murine ovaries in each group were cultured in vitro to test the number of ovarian glucose and the serum hormone level . Results After in-
sulin resistance took place in murine ovaries , significant statistical difference was found between DEX a group and saline group as to 2-deoxy-D-[1,2-3H]-glucose, liver, adipose and ovarian tissues (P<0.05).Ovaries in CRY a group increased significantly compared with DEX a group([2805.2 ±921.5]DMP/mg vs [1183.2 ±382.2]DMP/mg, P<0.01 ).Compared with DEX a group(37.5 ± 7.0, 5.0 ±1.8), the ovulation rate and the average corpus luteum in saline group (26.3 ±5.9, 3.5 ±1.6) and CRY group (27.2 ± 6.3,3.8 ±0.9) decreased (P<0.05).In comparison to DEX a group, the estrogen and progestogen levels in saline group and CRY a group decreased significantly(P<0.05).The expression level of AKT2 protein in DEX a group was much lower than that in saline group([0.39 ±0.01] vs [0.77 ±0.03], P<0.05).The glucose uptake in ovarian tissues cultured in vitro in blank control group , DEX b group, CRY b group and WT group was respectively (3447.2 ±1245.2)DMP/mg, (1183.2 ±382.2) DMP/mg, (2805.2 ± 921.5) DMP/mg, and (1364.2 ±292.3) DMP/mg.DEX b group decreased significantly compared with blank control group , DEX b group and WT group decreased significantly in comparison to CRY b group (P<0.05).In comparison to blank control group, the me-dium testosterone level increased and the protesteron level decreased significantly in DEX b group (P<0.05). Conclusion Tradi-tional Chinese medicine cryptotanshinone can relieve ovarian insulin resistance in vitro and in vivo , and it may exert insulin sensitivza-tion through PI3K pathway.

Based on the infrared spectra of Lophatheri Herba and Commelinae Herba, one-dimensional infrared spectra, second derivative spectra and two-dimensional correlated spectra were used to find out the differences between Lophatheri Herba and its imitations, respectively. The common peak ratio and variant peak ratio dual-indexes sequential were calculated and established according to infrared spectra of eleven batches of herbs. Infrared spectral data of Lophatheri Herba cluster analysis was applied to explore the similarity between each sample. The grouping results trend of sequential analysis of dual-indexes and cluster analysis was accordant. The results showed that the differences could be found by multi-level identification, and the source and the quality of the herbs could be effectively distinguished by the two analysis methods. Infrared spectroscopy, used in the present work exhibited some advantages on quick procedures, less sample required, and reliable results, which could provide a new method for the identification of traditional Chinese medicine with the imitations and adulterants, and the control of quality and origin.
