Objective To conduct a preliminary study on the efficacy and mechanism of Chinese traditional medicine Zeguilongshuang capsule for benign prostatic hyperplasia (BPH). Methods 20 patients with BPH were randomized into treatment group and control group (10 patients in each group).The medical history,International Prostate Symptom Score (IPSS),digital rectal examination,ultrasonography and uroflowmetry were done at the baseline.Patients in the treatment group used two Zeguilongshuang capsules three times per day for one month with repeated IPSS and above-mentioned examinations. They underwent prostatectomy on the next day when the treatment was completed.Patients in the control group received prostatectomy directly. After the pathological diagnosis of BPH was made,the expression of basic fibroblast growth factor (bFGF),platelet-derived growth factor (PDGF) and androgen receptor (AR) in the BPH tissue were assessed by immunohistochemistry. Results Patients in the treatment group reported improvement of low urinary tract symptoms, the mean IPSS decreased by 11.2%,the mean volume of the prostate reduced by 16.7%,and the mean maximum flow rate increased by 35.6%.Compared with the control group,the expression of bFGF in BPH tissue was down regulated ( P

Objective:To investigate the relationship between EGFR mutations and pulmonary tuberculosis in lung adenocarcino-ma. Methods:We detected EGFR mutations in 506 patients with lung adenocarcinoma by PCR amplification and sequencing and ana-lyzed the relationship between the mutations observed and pulmonary tuberculosis. Survival analysis was performed using the Ka-plan-Meier method with log-rank tests. Result:A total of 218 patients showed EGFR mutations;of these patients, 25 had a clinical his-tory of pulmonary tuberculosis. Compared with lung adenocarcinoma patients with no history of tuberculosis, patients with a history of pulmonary tuberculosis showed higher incidence rates of EGFR mutations, especially of exon 21 (P=0.047, P=0.002). Higher incidence rates of EGFR mutations, especially of exon 21, were observed in patients with lung cancer and tuberculosis in the same lobe or the same side of the lung than in those who had lung cancer and tuberculosis in opposite sides of the lung (P=0.02, P=0.03). Survival analy-sis showed that adenocarcinoma patients with a history of pulmonary tuberculosis have 2-year survival rates lower than that of adeno-carcinoma patients with no history of the disease (P=0.039). In patients adenocarcinoma associated with tuberculosis patients without EGFR-TKIs treatment, the 2-year survival rates of EGFR mutation patients and those without EGFR mutation showed no statistically significant difference (P=0.948). At the same time, we got the same results in adenocarcinoma associated with tuberculosis patients with EGFR-TKIs treatment (P=0.425). Conclusion:Lung adenocarcinoma patients with a history of pulmonary tuberculosis have high-er incidence rates of EGFR mutations, and EGFR mutations are not related to disease prognosis.

OBJECTIVETo explore the methods and outcomes of a minimally posteromedial transverse incision in the hip knee flexion for the treatment of tibial avulsion fracture at the insertion of posterior cruciate ligament (PCL).

METHODSTwenty-one patients with tibial avulsion fracture at the insertion of PCL treated with a minimally posteromedial transverse incision in the hip knee flexion by cannulated screw fixation from March 2010 to March 2013 were retrospectively analyzed. There were 13 males and 8 females with an average age of 35.1 years old (ranged, 20 to 56 years). Eleven cases caused by traffic accident, 3 caused by falling, 4 caused by sport, 3 caused by heavy pounds. The injury duration ranged from 3 hours to 9 days with a mean of 3.5 days. The results of posterior drawer test were positive in all patients. Lysholm score was used to evaluated knee joint function.

RESULTSAll operations were successful without infection, vessel and nerve injuries and all incisions healed by first intention with the mean length of 5.8 cm (ranged, 5 to 6 cm). All patients were followed up from 7 to 23 months with an average of 12.7 months. The results of posterior drawer test were negative in all patients. X-ray films showed that all fractures healed. The Lysholm score was improved from preoperative 40.76±9.55 to 95.86±2.33 final follow-up (t=30.07, P=0.000).

CONCLUSIONTreatment of tibial avulsion fracture at the insertion of the posterior cruciate ligament through a minimally posteromedial transverse incision in the hip knee flexion with cannulated screw fixation is a better surgical procedure with the advantages of minimal incision, sufficient exposure, effective fixation, small scar and satisfactory effects.

Objective To evaluate the efficacy and toxicity of weekly docetaxel and cisplatin in previously untreated patients with advanced non-small-cell lung carcinoma. Methods Between January 2002 and December 2003 ,34 patients with pathologically comfirmed advanced non-small-cell lung carcinoma who had not received treatment were enrolled. The mean age was under 66 years. The patients received intravenous infusions of docetaxel(25 mg/m2,dayl ,8,15) with dexamethasone premedication and cisplatin(25 mg/m2,dayl ,8,15) ,followed by a week of rest. The remedies which were less than 6 regimens lasted to disease progression or severe toxicity. Therapeutic effect was evaluated by CT scan every two courses . The patients were followed up for 24 months. Descriptive statistics and SPSSIO. 0 software were used to analyse the results. Results 34 patients finished 90 courses. The mean was 2. 6 courses. All patients were followed up. Two patients achieved complete responses, ten patients achieved partial responses, ten patients achieved stable disease. An objective response rate of 35. 29% (95% confidence interval 19. 25%-51. 33% )was obtained. Patients life quality was significantly improved. The median time to progression was 4. 1 months, and median overall survival was 11 months. The 1-year survival rate was 47. 06% , the 2-year survival rate was 11.76% . Toxicities were mild. Grade 3 to 4 neutropenia (11.76%), anemia (5.88%), hyponatremia (5.88%), alopecie (17.64%) and nausea/vomiting (5. 88% ) were observed. Conclusion Weekly Cisplatin plus docetaxel is an effective and well-tolerated regimen in chemo-naive patients with advanced NSCLC. Well-designed clinical trials should be conducted.

Objective To compare the outcomes of powered-assisted septoplasty with CO_ 2 laser-assisted septoplasty. Methods Thitry patients with limited deviation of nasal septum were analyzed retrospectively. Among 30 patients, 18 underwent powered-assisted septoplasty and the rest underwent CO_ 2 laser-assisted septoplasty. The surgical results were assessed by the visual analogue scale (VSA) and acoustic rhinometry. Results VSA scores significantly improved in both groups after surgery (P

Objective To assess the safety of intrathecal administration of betamethasone.MethodsTwenty-four adult white rabbits of both sexes were randomly divided into four groups with 6 rabbits in each group.Group Ⅰ (blank control group)in which nothing was injected intrathecally;group Ⅱ(NS control group)in whichnormal saline(NS)0.2ml was injected into the subarachnoid space through great occipital foramen once a weekand the animals were killed at the end of the 3rd week;in group Ⅲ and Ⅳ betamethasone 200 ?g or 400 ?g in 0.2ml was injected intrathecally once a week instead of NS.The animals were anesthetized and killed by intra-aorticinjection of NS and 2% glutaraldehyde.The cervical section of the spinal cord(C_(1-6))was immediately removedand fixed with 2% glutaraldehyde for microscopic examination.Results No neural histo-pathologic changes shownby microscopic examination were observed in group Ⅰ and Ⅱ.In group Ⅲ and Ⅳ microscopic examination showeddifferent degrees of swelling and demyelination of the nerve fibers and edema and vacuolization ofmitochondria.Conclusion Intrathecal betamethasone can damage the spinal cord.

OBJECTIVETo search for the optimal strategies for sperm collection from the patient with temporary penile erectile dysfunction (ED) on the day of oocyte pick-up ( OPU) in in vitro fertilization embryo transfer (IVF-ET).

METHODSWe retrospectively analyzed 93 cases of temporary ED on the OPU day of IVF-ET from January 2011 to May 2014, with fresh semen for 45 cases (group A), cryopreserved sperm before oocyte retrieval for 30 cases (group B), and frozen oocytes for 18 cases (group C). Group A was again subdivided into A1 (n = 18) and A2 n = 27) , the former intervened with oral sildenafil while the latter left untreated. We compared the rates of fertilization, high-quality embryo, and pregnancy among different groups.

RESULTSNo statistically significant differences were found among groups A, B and C in the age of the males and females, duration of infertility, numbers of obtained and mature oocytes, and rates of cleavage, or in the percentages of normal fertilization (80.78% vs 80.43% vs 84.77%), high-quality embryo (53.27% vs 52.97% vs 47.69%) and pregnancy (60.00% vs 56.77% vs 44.44%) (all P > 0.05). The rate of 3PN was markedly lower in group C (0.63%) than in A (9. 61%) and B (4.34%) (P < 0.05). There were no significant differences between groups A1 and A2 in the age of the males and females, duration of infertility, numbers of obtained and mature oocytes, and the rates of fertilization, cleavage, high-quality embryo, and pregnancy (all P > 0.05).

CONCLUSIONOn the OPU day of IVF-ET, oral sildenafil can help temporary ED men to achieve penile erection and ejaculation without affecting the outcomes of assisted reproduction. Cryopreserved sperm can be used in case of predicted temporary ED and frozen oocytes can also be employed if sperm retrieval fails. However, to avoid puncture injury to the epididymis or testis, fresh semen should be the first choice.
