Objective:To observe the clinical effects of electroacupuncture (EA) plus acuoint-injection for nerve root sciatica.
Methods:A total of 114 cases were randomly divided into an observation group and a control group, 57 cases in each group. The observation group was given EA plus acupoint-injection therapy with Cobamamide. The control group was given oral administration of Diclofenac Sodium Sustained-release Tablets plus muscular injection of Cobamamide. After one-course treatment, the clinical effects were compared between the two groups.
Results:The total effective rate was 96.5%in the observation group and 91.2%in the control group, without a statistical significance in the difference between the two groups (P>0.05). The curative rate was 57.9%in the observation group and 21.1% in the control group, with a statistical significance in the difference between the two groups (P<0.05). In the follow-up on the fourth day after the treatment, the recurrence rate was 23.1%in the observation group and 47.9%in the control group, with statistical difference between the two groups (P<0.05).
Conclusion: EA plus acupoint-injection therapy for sciatica of nerve roots is remarkable in the clinical effect and needs promotion in clinic.

Objective To evaluate percutaneous endoscopic gastrostomy (PEG) for long-term enteral nutrition in patients with cancers of head and neck. Methods PEGs were performed for 12 patients with head and neck cancers, the indication for which included serious buccal mucositis, difficulty in swallowing, anorexia, and obstruction of the digestive tract. Before PEG and 8 weeks after PEG, serum concentrations of total protein and albumin of the patients were measured, body composition including body weight, free fat mass, and fat mass were measured by bioelectric impedance analysis (BIA), and Karnofsky performance score ( KPS) was evaluated. Results After enteral nutrition for 8 weeks through PEG, the serum concentrations of total protein and albumin of the patients increased significantly (63.8?0.3g/L vs 57.4?0.2g/L, P

Objective To investigate the feasibility and technique of laparoscopic subtotal cholecystectomy(LSC).Methods Totally 168 patients were converted to LSC because of failure in laparoscopic cholecystectomy(LC).During the LSC,the Calot's triangle was separated and then the Hartmann's pouch was incised to decreased the intracystic pressure for the removal of the stones.Results Among the cases,5 patients were converted to open surgery for subtotal resection of the gallbladder.LSC was completed after clipping the cystic duct and artery in 122 patients;in the other 41 cases,the gallbladder was cut at the Hartmann's pouch to clip the bile duct and artery or suture the neck of the gallbladder,and then LSC was performed.The median operation time was(65.5?15.2)min,and the intraoperative blood loss was(71.5?15.5)ml.The time to resume the diet was(20.4?6.3)h postoperation.After the operation,7 patients developed local complications(4.2%),and the mean postoperative hospital stay was(4.2?2.6)d.Of the patients,105 were followed up for(25.5?6.5)months,during this period,5 patients had dyspepsia,3 had right shoulder pain,and 9 had right hypochondrium pain.Conclusions LSC is feasible for patients with complicated cholecystitis.It is important to control the perioperative hemorrhage and bile leakage.

Objective To guide bracing treatment for adolescent idiopathic scoliosis (AIS). Methods A total of 68 AIS patients with apex vertebrae (AV) under T6 had received the improved Cheneau bracing treatment between March 2008 and June 2010. All patients were divided into two groups. There were 16males and 35 females, with a mean age of 13.6 years (range, 10.6-17.2) in the intervention group. The mean Cobb angle was 29.5° (range, 20°-38°); Risser sign was 2-4; Vertebralrotation degree was 0-2 in the group;while there were 6 males and 11 females, with a mean of 13.2 years (range, 10.8-16.8) in the control group.The mean Cobb angle was 28.7° (range, 20°-37°); Risser sign was 2-4; Vertebralrotation degree was 0-2 in the control group. All patients in control group were informed standardized bracing treatment method. But we gave patients in intervention group two copies of "The Form of Guiding Bracing Treatment" treatment of patients with AIS, and informed that they carried out the bracing treatment according requirement of the form.Cobb angle was measured before the treatment and at 6th, 12th, 18th month after treatment. Results Sixtyfive cases were followed up for 18-27 months. However, one female in control group and two females in intervention group were lost during follow-up. Coefficient and intraclass correlation coefficient of form were both over 0.60. The acceptance rate of the table was 97.54%(199/204), qualified rate was 100.00%( 199/199), and with good content validity. The mean Cobb angle decreased gradually from 28.71° to 25.76° in control group and from 29.47° to 21.59° in intervention group. Four cases in control group and 34 cases in intervention group had reduced more than 5° at 18 months after treatment. There was significant difference regarding Cobb angle between two group. Conclusion The form of guiding bracing treatment has good reliability and validity and can guide bracing treatment of AIS correctly and effectively.

Objective To investigate the relationship between body mass index (BMI) and dose area product (DAP) as well as fluoroscopy time during coronary angiography (CAG) in Han nationality subjects in order to improve early judging and reducing high radiation risk. Methods CAG materials of 451 Han nationality subjects were retrospectively analyzed. The patients included 276 males (age 32-87 years) and 175 females (age 42-84 years), and the BMI values ranged from 17.30 to 35.42 kg/m2. According to BMI values, the patients were divided into group A(BMI<20 kg/m2,n=25), group B (BMI 20-24.9 kg/m2,n=204), group C (BMI 25-29.9 kg/m2,n=192) and group D (BMI>30 kg/m2,n=30). The mean DAP and fluoroscopy time of each group were calculated; the DAP values were compared between each other among the four groups by using nonparametric Kruskal-Wallis test, while the fluoroscopy time was compared between each other among the four groups by using single factor analysis of variance or LSD-t test. Results The mean DAP of group A, B, C and D was(1 070.07±541.33) μGym2,(1 326.82±606.91) μGym2,(1 937.99±1 030.31) μGym2 and (2 654.53±1 296.69) μGym2 respectively. The mean fluoroscopy time of group A, B, C and D was (3.53± 2.08) min, (2.70 ±1.80) min, (2.75 ±1.88) min and (2.71 ±1.69) min respectively. Statistically significant difference in DAP values existed between each other among the four groups (P<0.05) except between group A and group B (P=0.232). Statistically significant difference in fluoroscopy time existed between group A and other three groups (P<0.05), while the difference in fluoroscopy time between each other among B, C and D groups was not significant (P>0.05). Conclusion The DAP values of adult Han subjects receiving CAG are increased with the increase of BMI values; the fluoroscopy time is significantly prolonged in patients with BMI<20 kg/m2. In performing interventional procedure, the operator should not only understand that the increase of BMI can cause the increase of DAP, but also need to pay special attention to the increase of DAP value caused by operation difficulty when the patient’s BMI is <20 kg/m2.
