Objective　To investigate the association betwee n the β3-adrenergic receptor gene (β3-AR) and obesity. Methods　147 patients with obesity and 106 controls were selected. Genotype of the β 3-AR was determined by polymerase chain reaction (PCR) and restriction fragme nt length polymorphism methods (RFLP). Body mass index (BMI) was detected. Results　The frequency of Arg64 allele of β3-AR gene in the obesit y g roup (20.3%) was significantly higher than those in the control group (10.2%) ( P=0.001) . The distribution of Trp64Arg and Arg64Arg genotype in the patient group (38.7% and 0.9%) were both higher than that in the control group (19.0% and 0.7%). In the female subj ects, the Trp64Arg mutation and frequency of Arg64 allele of the β3-AR gene in the obesity group(40.6% and 20.3%) were also higher than those in control (16 . 7% and 9.5%)(P<0.01). Conclusions　These results suggest th at the Trp64Arg mutation of the β3-adrenergic-receptor gene may be associat ed with increased body fat.

OBJECTIVETo study the relationship between the inheritable factor and environmental factors of type 2 diabetes mellitus in humans.

METHODSA case-control study based on 154 type 2 diabetes mellitus and 130 healthy controls was carried out in Jiangsu Province in 1997.

RESULTSThe age, family history of diabetes mellitus, hypertension history, high waist/hip ratio (WHR), high systolic blood pressure, huge fetus history, and the genotype of beta(3)-adrenergic receptor (beta(3)-AR) were the risk factors of type 2 diabetes mellitus; while occupational physical activity was protective factor of type 2 diabetes mellitus. The risk for diabetes mellitus distinctly increased while genetic factor and obesity, beta(3)-AR mutation were coexisting.

CONCLUSIONType 2 diabetes mellitus is caused by the effect of both genetic and environmental factors.

Objective To explore the therapeutic efficacy of Shixiaosan and Siwu decoction combined with rehabilita-tion intervention used for pelvic floor dysfunction. Methods The 126 cases were randomly divided into test and control groups. There were 63 patients in every group. The control group accepted only two courses of pelvic floor rehabilitation therapy. However treatment of traditional Chinese medicine combined with two courses of pelvic floor rehabilitation therapy were used in the test group. Then the therapeutic effect of all cases was estimated. The incidence of stress in-continence was investigated after one year. Results The amount of pelvic floor muscle strength up to Ⅲ in the test group was 58 cases, however only 41 cases in the control group. There were 5 cases suffered stress incontinence, and the incidence was 7.9% in the test group. But there were 14 cases suffered stress incontinence, and the incidence was 22.2% in the control group. 3 cases occurred anorectum dysfunction, and the incidence was 4.8% in the test group,however there were 11 cases occurred anorectum dysfunction, and the incidence was 17.5% in the control group. 4 cases suffered pelvic organ prolapse,and the incidence was 6.3% in the test group,while there were 13 cases suffered pelvic organ prolapse, and the incidence was 20.6% in the control group. The difference between the two groups was statistically significant (P<0.05). Conclusion Our study indicated that the therapeutic efficacy of Shixiao san and Siwu decoction combined with rehabilitation intervention used for pelvic floor dysfunction was significantly better than simple rehabilitation intervention.

Objective To study the effect of acupuncture combined with clean intermittent catheterization in the treat-ment of neurogenic bladder. Methods A total of 46 patients were randomly divided into test and control groups. There were 23 patients in the each group. The clean intermittent catheterization only used in the control group. However inte-grated acupuncture and clean intermittent catheterization were used in the test group. Final the residual urine volume and the incidence of bacteriuria were researched after 5 months. Results There were 17 cases restored the micturating function in the test group, however only 7 cases in the control group. There were 3 cases suffered bacteriuria in the test group, but there were 11 cases suffered bacteriuria in the control group. The difference between the two groups was sta-tistical ly significantly (P<0.05). Conclusion Combined acupuncture with clean intermittent catheterization can effi-ciently maintain the normal function of bladder, decrease the residual urine volume, and reduce the incidence of bac-teriuria.
