Objective To evaluate the clinical efficacy of laparoscopic radical prostatectomy.Methods A total of 11 cases of laparoscopic radical prostatectomy were enrolled in this study.Among the cases,transperitoneal approach was used in 4 patients,and extraperitoneal approach was employed in 7.The prostate,seminal vesicles,and ampulla ductus deferens were resected,and then the bladder was anastomosed with the urethra.Results The operation was successfully performed in all the patients with a mean operation time of 304 min(180-390 min),and a mean blood loss of 520 ml(300-1200 ml).The postoperative catheterization time and hospital stay were 12-28 d(mean,19.8 d)and 12-24 d(mean,20 d)respectively.No injuries to the rectum,urinary incontinence,or urethral stenosis occurred in this series.The patients were followed up for 1-36 mon(mean 11 mon),during this period,no local recurrence or distant metastasis were found.The postoperative PSA level was 0-0.05 ?g/L.Conclusion Laparoscopic radical prostatectomy is safe and effective for the treatment of prostate cancer.

BACKGROUND:Studies have shown that bone marrow mesenchymal stem cel transplantation can improve disease conditions by reducing inflammation.
OBJECTIVE:To explore the therapeutic efficacy of bone marrow mesenchymal stem cels on chronic asthma rats.
METHODS: A rat model of chronic asthma was established by intraperitonealy injected and aerosolized ovalbumin. After modeling, rats were given 4×105 and 8×105 bone marrow mesenchymal stem celsvia the tail vein, respectively. Thirty days later, the lung tissues were observed pathologicaly using hematoxylin-eosin staining; RT-qPCR and ELISA methods were employed to test the changes in interleukin-10, tumor necrosis factor-α and interferon-γ levels in lung tissue and peripheral blood, respectively.
RESULTS AND CONCLUSION:Rat models of chronic asthma were successfuly established after intraperitoneal injection of ovalbumin combined with aerosolized ovalbumin. After 30 days of cel treatment, the structure of lung tissues were obviously recovered, and the levels of interleukin-10, tumor necrosis factor-α and interferon-γ showed some improvement in lung tissue and peripheral blood, but there were no differences between the two groups. In conclusion, bone marrow mesenchymal stem cels show some potential role in the treatment of chronic asthma.

OBJECTIVE:To compare therapeutic efficacy and safety of laparoscopy combined with dienogest and laparoscopy combined with dienogest and TCM in the treatment of endometriosis. METHODS:126 endometriosis patients were selected and divid-ed into control group and observation group,with 63 cases in each group. Control group received combined with dienogest(25 mg/time,qd);observation group was additionally given TCM on the basis of control group. Therapeutic efficacy,recovery time of ovula-tion,menstrual recovery time and ADR were compared between 2 groups,and recurrence and pregnancy of them were followed up for 2 years. RESULTS:The total effective rate of observation group (93.65%) was significantly higher than that of control group (80.96%),with statistical significance (P<0.05). The menstrual recovery time and recovery time of ovulation in observation group were significantly shorter than control group,with statistical significance (P<0.05). The incidence of ADR in observation group (9.52%)was significantly lower than control group(26.98%),with statistical significance(P<0.05);the recurrence rate of observa-tion group (4.76%) was significantly lower than that of control group (17.46%),with statistical significance (P<0.05). In 2-year follow-up,there were 23 pregnancy patients in observation group,which was significantly higher than that of control group (9 cas-es),with statistical significance (P<0.05). CONCLUSIONS:Laparoscopy combined with dienogest and TCM in the treatment of endometriosis have better clinical effect,higher safety and lower recurrence rate. The patients are easily pregnant.

Objective To investigate the occurring time,pathogen distribution and drug resistance in kidney transplant pa-tients with lung infection and to provide basis for clinical treatment.Methods From January 2012 to December 2015,73 kid-ney transplant patients with lung infection were collected in this study.The timing of infection occurrence,the main source of specimen,the pathogenic bacteria and drug resistance of each case were analyzed retrospectively.The drug sensitivity was analyzed by WHONET 5.4 software.Results 83.56% (61/73)cases of lung infection occurred within 1 year in kidney transplant patients,among them,53.42% (39/73)cases occurred within 6 month after kidney transplantation,and 30.14%(22/73)cases occurred within 6~12 months after surgery.The 84.93% (62/73)source of specimen were sputum and blood,and the others were alveolar lavage fluid,pleural fluid and throat swab.Totally 7 9 strains of pathogenic bacteria were isolated,including gram negative bacilli (49.37%),gram positive bacteria (39.24%)and fungi (11.39%).The most com-mon strains were Pseudomonas aeruginosa 12 strains (15.19%),Staphylococcus aureus 11 strains (13.92%),Klebsiella pneumoniae 10 strains (12.66%),Staphylococcusaureus 9 strains (11.39%),BaumanAcinetobacter 8 strains (10.13%), and Escherichia coli 6 strains (7.5 9%).The detection rate of strains which producing broad-spectrumβ-lactamases were 30.0% in Escherichiacolil and 20.0% in Klebsiellapneumonia,respectively.Furthermore,the detection rate of methicillin-resistant Staphylococcus were 45.45% in Staphylococcusepidermidisl and 22.22% in Staphylococcusaureus,respectively. The drug sensitivity results showed that the Gram-negative bacilli were sensitive to Vancomycin,teicoplanin and rifampicin. The Gram-positive cocci were sensitive to Cefepime,meropenem and imipenem.Conclusion 83.56% (61/73)cases of lung infection occurred within 1 year in kidney transplant patients;Gram-negative bacteria were the main pathogenic bacteria in lung infection in kidney transplant patients;Gram-negative bacteria and Gram-positive bacteria were multi drug resistant and should be treated as early as possible.
