Purpose:To investigate the effect of antineoplastic polypeptide from Buthus martensii venom (APBMV) on the cultured human promyelocytic leukemia cells HL 60 and hepatoma cell line SMMC 7721 and hepatoma H 22 bearing mice.Methods:MTT colorimetric method, growth inhibiting test and colony formation assay were used in the in vitro test. H 22 bearing mice were applied in the in vivo experiment. Through measuring tumor growth inhibitory rate(IR),white blood cell (WBC) number and spleen index (SI) ,we explored the influence of APBMV on H 22 bearing mice.Results:APBMV possessed stronger cytotoxicity on HL 60 cells and SMMC 7721 cells, and IC 50 was 10.74 ?g/ml and 11.33 ?g/ml , respectively. APBMV could dramatically inhibit their growths. There were obvious dosage response correlations. The IC 50 of HL 60 and SMMC 7721 at 24h, 48h and 96h were 19.41 ?g/ml, 9.90 ?g/ml, 11.41 ?g/ml and 15.87 ?g/ml, 13.05 ?g/ml, 8.70 ?g/ml, respectively. When the concentration of APBMV exceeded 8 ?g/ml, the colony formation rate of SMMC 7721 cells decreased dramatically ( P 0.05).Tumor growth of H 22 bearing mice was markedly inhibited by APBMV,the growth inhibiting rate was reached 40.30% ( P

AIM:To observe the changes of macular thickness in patients after cataract operation.
METHODS: A total of 126 patients ( 133 eyes ) were divided into two groups that were included in this study. The group (68 eyes of 64 case) with phacoemulsification combined intraocular lens implantation and ( 65 eyes of 62 cases ) with manual small incision cataract surgery ( MSICS) . There was no complication before and during the surgery. Optical coherence tomography ( OCT) was examined 1, 3mo before and after surgery. The visual acuity and macular thickness were compared after surgery. The SPSS 17. 0 software was used for statistical analysis. The paired t-test was used before and after surgery. Independent-samples t test was used in two groups before and after surgery,α=0. 05.
RESULTS: The cataract phacoemulsification group:preoperative and 1mo after surgery, the mean macular thickness was 241. 3±10. 9μm and 279. 7±16. 5μm, with significant difference ( P < 0. 01 ). The mean macular thickness was 245. 6±12. 6μm 3mo after surgery without statistical difference compared with preoperative ( P>0-05). The mean macular thickness was 279. 7±16. 5μm 1mo after surgery and 245. 6±12. 6μm 3mo after surgery with statistical difference(P<0. 05). Three eyes displayed cystoid macular edema at 1mo after surgery and 2 eyes of them was resolved 3mo after surgery. The group of MSICS: preoperative and 1mo after surgery, the mean macular thickness was 240-5±11. 9μm and 280. 7±16. 8μm, with significant difference (P<0. 01). The mean macular thickness was 246. 6±13. 2μm 3mo after surgery without statistical difference compared with preoperative ( P >0-05). One month after surgery and 3mo after surgery, the mean macular thickness were 280. 7±16. 8μm and 246-6±13. 2μm, with statistical difference (P<0. 05). Two eyes displayed cystoid macular edema at 1mo after surgery and 2 eyes were resolved 3mo after surgery. Between the two groups pre-operation or after operation for 1, 3mo respectively P values were without statistical difference (P>0. 05).
CONCLUSION: The macular thickness and macular edema can be found 1mo after cataract phacoemulsification and MSICS. Three months post-operatively, macular edema disappears and does not show statistical difference compared with preoperative. The increase of macular thickness has no obvious relationship with the choice of surgery.

Objective To investigate the risk factors and treatment efficiency for lung cancer patients with venous thromboembolism (VTE). Methods Total 282 cases of lung cancer patients with VTE were enrolled into two groups , including the VTE group and the non-VTE group , for comparation analysis based on a series of clinical data. Results The occupation rate of adenocarcinoma and Ⅳ period were 65.28% and 87.50% in VTE group, respectively, higher than those of 51.43% and 75.71% in the non-VTE group. The increased rate of blood viscosity and d-dimer respectively were 65.28% and 70.83%, higher than those of 51.43% and 56.67% in the non-VTE group, with significant differences (P < 0.05, respectively). Result of logistic regression analysis showed that tumor stage , d-dimer levels , smoking , age , and blood viscosity levels were highly correlated with venous thrombosis in patients with lung cancer, and the OR value among them was 3.802, 2.339, 5.814, 3.875 and 6.404, respectively, with significant differencees (P < 0.05, respectively). Conclusions Lung adenocarcinoma with stage Ⅳ, smoking , age and increase of blood viscosity and d-dimer were the important risk factors for VTE in patients with lung cancer chemotherapy. Timely assessment of risk factors and early anticoagulation therapy in lung cancer patients with venous thromboembolism associated with VTE can improve the treatment efficacy and reduce the complications.

OBJECTIVETo critically evaluate the currently available randomized clinical trials regarding the effectiveness of acupuncture in palliative care for cancer patients, hence, to provide sufficient evidences for the widespread use of acupuncture in cancer treatment.
METHODSTwo independent reviewers extracted data from all of the randomized clinical trials (RCTs) that assessed the efficacy of acupuncture in palliative care for cancer patients. Seven databases were searched from their respective inception to December 2010. All eligible trials identified were evaluated by two independent reviewers using the Jadad scale, and data from the articles were validated and extracted.
RESULTSIn total, 33 RCTs met the inclusion criteria. The effects of acupuncture on different cancer-related aspects were shown, including chemotherapy or radiotherapy-induced side effects (13/33, 39.4%), cancer pain (6/33, 18.2%), post-operative urinary retention (4/33, 12.1%), quality of life (2/33, 6.1%), vasomotor syndrome (2/33, 6.1%), post-operative gastrointestinal dysfunction (2/33, 6.1%), prevention of prolonged postoperative ileus (2/33, 6.1%), joint symptoms (1/33, 3.0%), and immunomodulation (1/33, 3.0%).
CONCLUSIONSThe result of our systematic review suggested that the effectiveness of acupuncture in palliative care for cancer patients is promising, especially in reducing chemotherapy or radiotherapyinduced side effects and cancer pain. Acupuncture may be an appropriate adjunctive treatment for palliative care.

Objective To investigate the value and safety of biopsy guided by colposcopy in diagnosis of cervical diseases in pregnant women.Methods From Aug.2007 to Feb.2009.17 828 pregnant women who receive antenatal examination underwent cervical cytological screening thinprep cytology test(TCT)in Beijing Obstetrics and Gynecology Hospital.If abnormal cytological results were found,those preguant women were administered by eolposcopic examination and biopsy after they signed informed consent.Results (1)TCT:the abnormal TCT results of 1502 preguant women(8.425%,1502/17 828) were found in 17 828 cases.(2)Colposeopie examination:two hundred and four pregnant women underwent colposcopic examination.The rate of satisfied colposcopic imaging wag 92.6%(189/204),colposcopic examination identified 125 cages with cervical inflammation or cervical intraepithelial neoplasia (CIN)Ⅰ,25 cases with CIN Ⅱ and 54 cases with CIN Ⅲ or microinvasive squamous carcinoma (MIVC) of squamous cervical carcinoma(SCC).(3)The results of biopsy guided by colposcopy:among 204 cases,it was found 33 cases with cervical inflammation or wart,95 cases with CIN Ⅰ,28 CIN Ⅱ,36 cases with CIN Ⅲ and 12 cases with MIVC. (4) The rate of concordance: compared with biopsy pathologic examination, colposcopy examination found 113 cases with cervical inflammation and CIN Ⅰ , the rate of concordance was 90. 4%(113/125). And 54 cases with CIN Ⅲ or SCC diagnosed by colposcopy examination, however biopsy pathologic examination confirm 23 cases with CIN % and 10 cases with SCC at stage Ⅰ a, the concordance rate was 61% (33/54). (5) Complication: eight (3.9%, 8/204) pregnant women underwent cervical wound suturing due to continuous bleeding after colposcopy exam or biopsy. No other complications were recorded. Conclusions It is necessary that TCT should be performed in pregnant women without cytological screening within one year. Colposcopic examination and biopsy were indicated if pregnant woman with abnormal cytological result were found. Pregnant women with cervicitis or CIN Ⅰ diagnosed by colposcopy should be followed up. If pregnant woman was suspected with CIN Ⅱ or advanced disease, biopsy guided by colposcopy should be performed.

OBJECTIVETo determine whether testosterone-induced intra-testicular testosterone withdrawal and therefore spermatogenic impairment is associated with looser arrangement of spermatogenic cells in rats.
METHODSAdult male SD rats received intramuscular injection of testosterone undecanoate at 19 mg/(kg x 15 d) for 130 days, and then testicular tissue blocks were obtained for the preparation of methacrylate resin-embedded sections and observation of the changes in testicular histology.
RESULTSApart from such changes as impaired spermiogenesis and spermiation, apparently looser arrangement of spermatogenic cells was seen in 11.5% of the seminiferous tubule profiles, with radial cracks (empty spaces) running towards the tubule lumen being formed between lines, bundles or groups of spermatogenic cells (mainly spermatids and spermatocytes).
CONCLUSIONLooser arrangement of spermatogenic cells is one of the key histological changes resulting from intra-testicular testosterone withdrawal in rats.
