Primary biliary cirrhosis(PBC) is a chronic,progressive cholestatic liver disease of unknown cause that usually affects middle-aged women.Ursodeoxycholic acid(UDCA)is the first selected drug to PBC which has definite effect.Treament of PBC with UDCA combined with immunodepressant become presents research focuses.Liver transplantation is the only treatment of the final stage of PBC.

ObjectiveTo study changes of bone measured with quantitative ultrasound (QUS) in women of Guangzhou area and provide scientific basis for prevention and treatment of osteoporosis (OP).MethodsCalcaneus measurement was done with QUS in 647 women of Guangzhou area, and measurement data was analyzed.ResultsIn menopause and aged women, broadband ultrasound attenuation (BUA) showed a significantly decrease (P<0.01), whereas it decreased only slightly in early postmenopausal women (P>0.05). After the peak of BMD, speed of sound (SOS) showed a stepwise decline, and significantly decrease in menopause (P<0.01), but not significant over eighties (P>0.05). In contrast, stiffness index (STI) significantly decreased from the menopause, and it was a better indicator than BUA or SOS.ConclusionQUS can not only test bone mass but also assess microarchitecture, and it is nonradioactive, cheaper, easier to use, and may play a important role in diagnosis of osteoporosis and women and senile health.

950 mg/d) group was significantly higher than those in median or low calcium intake group,among girls with BB genotype. However,such significant effect was not detected among girls with b allele. Conclusion:The PTH BstBⅠ polymorphism has significant interaction effect with calcium intake on bone mass accretion in Chinese adolescent girls. High calcium intake would be beneficial to gain higher bone mass accretion for girls with BB genotype than those with b allele.

Objective To explore whether antibiotic prophylaxis is beneficial in tension-free in-guinal hernia repair Method A perspectiverandomized controlled study was conducted which included 1 28 patients who underwent tension-free inguinal hernia repair from July 201 1 to August 201 3.In the anti-biotic prophylaxis group,antibiotic was intravenously administrated within 30 minutes before surgery.In the control group,no preoperative antibiotic wasadministrated.The incidence of incision infection was com-pared between groups.Result Incision infectiondeveloped in onepatient of the antibiotic prophylaxis group and two patientsin the placebo group,indicating no significant difference between the groups(P >0.05).Conclusion Before tension-free repair,there is no real need to apply prophylactic antibiotics reg-ularlyfor inguinal hernia without high risk factors.

Objective To evaluate the efficacy and toxicities of intensity modulated radiation therapy (IMRT) with or without concurrent chemotherapy in the treatment of cervical cancer patients with para-aortic lymph node (PALN) metastases after initial treatment.Methods From Oct 2008 to Aug 2013,56 cervical cancer patients with PALN metastases after initial treatment,including radical resection or pelvic radiotherapy/chemoradiotherapy,were selected for analysis.The delivered radiation dose to PALN was 55-60 Gy for GTV and 45-50 Gy for CTV respectively with 25-30 fractions during 5-6 weeks.36 patients received concurrent paclitaxel (135 mg/m2) and cisplatin (60 mg/m2) chemoradiotherapy (CRT group) and 20 patients received RT alone (RT group).Results The median follow-up time after treatment was 22.7 months (2.7 to 74.4 months).98.2％ (55/56) of patients completed RT.In CRT group,38.9％ underwent concurrent TP regimen 2-3 cycles and the rest completed one cycle.The rates of CR plus PR in CRT and RT groups were 91.7％ (33/36) and 85％ (17/20),respectively (x2 =0.516,P ＞0.05).The 3-year overall survival rate in CRT group and RT group were 57.5％ and 32.7％ (x2 =4.059,P ＜ 0.05),and 3-year progression-free survival rates were 50.4％ and 29.2％ (x2 =4.184,P ＜ 0.05),respectively.TP regimen concurrent chemoradiotherapy was more effective than radiotherapy alone.The 3-year overall survival rate was 53％ and 39.5％ in patients with isolated PALN and nonisolated PALN,respectively (x2 =4.265,P ＜ 0.05).Grade 3 or 4 acute leukopenia was found in 10 (27.8％,CRT group) and 6 (30％,RT group) patients (x2 =0.693,P ＞ 0.05).Grade 3 gastrointestinal toxicity occurred in 1 patient each group (x2 =0.847,P ＞ 0.05).Conclusions TP regimen concurrent CRT is associated with better survival than RT alone,and the treatment toxicities could be tolerant.

Objective To analyze the feasibility, safety, and technique of laparoscopic myomectomy in patients with large hysteromyoma. Methods A total of 82 hysteromyoma patients with the uterus larger than 14-week gestational size were treated by laparoscopic myomectomy. The outcome of the operation were compared with that in 182 hysteromyoma cases with the uterus smaller than 14-week gestational size. Results In the 82 patients with the uterus larger than 14-week gestational size, 77 were treated successfully by laparoscopy, in which pneumoperitoneum was used in 68 cases and gasless laparoscopy in the other 9. One of the cases converted to open surgery, and small abdominal incision was made in 4 patients. Compared with the patients with the uterus smaller than 14-week gestational size, the 77 patients who had been successfully by laparoscopy had longer operation time [(157.6?89.7) min vs (35.3?26.2) min, t=16.926, P=0.000] and more blood loss [(218.0?108.2)ml vs (108.5?67.5)ml,t=9.904,P=0.000]. Conclusions Myomectomy can be performed under a laparoscope for patients with the uterus larger than 14-week gestational size. Highly skilled technique is important for the surgery.!Gasless laparoscopy is applicable to myomectomy for patients with the uterus smaller than 16-week gestational size.
