Objective: To review the problems existing in the development and application of current electroacupuncture (EA) apparatuses, and provide reference for the development of EA apparatuses. Methods: Related literatures about EA apparatus were derived from China National Knowledge Infrastructure (CNKI), Wanfang Academic Journal Full-text Database (Wanfang) and Chongqing VIP Database (CQVIP) between 2013 and 2017. Literatures about the development of EA apparatuses and the application for experimental research and clinical treatment published in Chinese journals were retrieved, and the development and application of EA apparatuses were summarized. Results: Among the 107 selected literatures, 48 types of EA apparatuses were used, of which only 11 models could be found in the registration list and within the validity period. There was no registration information for the EA apparatus newly developed in the past 5 years. The EA parameters used in experimental research and clinical treatment in Chinese medicine were different, and the combination of stimulation parameters was diverse. Conclusion: At present, most of the new EA products are still in the experimental or research stage, and the transformation of results has not yet been achieved. Moreover, there is no unified standard for the use of EA apparatus and its stimulation parameters in experimental research and clinical treatment, which is not conducive to the standardization process of EA stimulation.

Objective: To assess physical activity level and characteristics in elementary physical education (P.E.) class among different weight status and grades students. Methods: ActiGraphGT3X was used to measure physical activity of 60 students in grade 1, 2, and 4 during three P.E. classes. BMI was calculated according to the student s height and weight in the latest physical fitness test results, and the weight status was divided according to the national Physical Fitness Standards for Students in different grades of elementary schools. Independent sample t test and analysis of variance were used to explore the difference of physical activity. Results: The proportion of moderate to high intensity physical activity (MVPA) in elementary school P.E. class was 21.9% (8.8 min). The proportion of MVPA in P.E. classes and the number of steps in normal weight students were 25.4% and (1 247.0± 326.3 ), respectively, which were significantly higher than those of underweight students, but not significantly different from those of overweight students. The MVPA of male and female PE classes in the second grade (27.0%, 26.4%) was significantly higher than that in the first grade, but there was no significant difference compared with that in the fourth grade ( P >0.05). Conclusion Moderate to high intensity physical activity is low in P.E. class in elementary school. Improving teachers awareness of promoting physical activity in PE class will benefit the MVPA in students.

OBJECTIVE:To analyze intervention effect of Drug Rational Usage Guidelines System(DRUGS)on antibacterial agents use in department of obstetrics and gynecology in our hospital. METHODS:The application of antibacterial agents in depart-ment of obstetrics and gynecology in our hospital during Jan.-May(before intervention)and Jun.-Nov. 2012(after intervention)were extracted in respects of drug name,preoperative medication duration,perioperative additional condition,postoperative drug with-drawal time,drug combination,usage and dosage,average hospitalization stay,hospitalization cost. The intervention effects were analyzed. RESULTS:After intervention,the type of antibacterial agents were more in line with national regulations;the proportion of type Ⅰ incision surgery without antibacterial agents increased from 57.8% to 75.2%;the prophylactic application of antibacteri-al agents in type Ⅱ incision surgery within 0.5-2 h increased from 80.2% to 97.0%. The rate of reasonable antibacterial selection, drug combination,usage and dosage increased from 76.9%,64.9%,71.3% to 89.3%,84.6%,90.2%,respectively. The average hospitalization stay and antibacterial cost per capita decreased significantly. There was statistical significance among above indica-tors before and after intervention(P<0.05 or P<0.01). CONCLUSIONS:DRUGS effectively change irrational use of antibacterial agents in department of obstetrics and gynecology,which provide a new method for the management of antibacterial agents.

Objective To explore the correlation between anaplastic lymphoma kinase (ALK) fusion gene detected by immunohistochemistry (IHC) and reverse transcription-polymerase chain reaction (RT-PCR) in non-small cell lung cancer. Methods The ALK fusion protein/gene in 71 patients of NSCLC which was detected both by IHC (1A4/1H7) and RT-PCR were retrospective studies, and the 2 methods were compared. Results Among the 71 NSCLC patients, the ALK fusion protein positive was in 21 cases and negative was in 50 cases by IHC detected, while the ALK fusion gene positive was in 12 cases and negative was in 59 cases by RT-PCR. The ALK fusion genes detected by RT-PCR were all negative when IHC negative and IHC 1+. All patients with IHC 2+ and IHC 3+ were confirmed ALK fusion genes positive with RT-PCR. The positive rate of ALK fusion protein detected by IHC in large surgical specimens was 28.95%(11/38), and the positive rate of ALK fusion protein detected by IHC in small biopsy specimen was 30.30%(10/33). The positive rate of ALK fusion gene detected by RT-PCR in large surgical specimens was 18.42%(7/38), and the positive rate of ALK fusion gene detected by RT-PCR in small biopsy specimen was 15.15% (5/33). Conclusions Although the ALK fusion protein detected by IHC may have certain false positive, IHC is highly consistent with RT-PCR in IHC 2+and IHC 3+ cases. The combination of IHC and RT-PCR can be used to ALK fusion gene positive NSCLC screening and diagnosis. The small biopsy specimen is also good material for ALK detection, when the surgical specimen can not be got from patients.

Background and purpose:Liver cancer resection and splenectomy are the main methods to treat hepatocellular carcinoma and hypersplenism. The aim of this study was to discuss the safety and feasibility of simultaneous radiofrequency ablation (RFA) and laparoscopic splenectomy (LS) for the treatment of small hepatocellular carcinoma with hypersplenism.Methods:Twenty-seven patients with small hepatocellular carcinoma and cirrhotic hypersplenism underwent RFA and LS. The clinical data were also analyzed.Results:The surgery was converted to an open surgery in 1 patient, while laparoscopic splenectomy in a hand-assisted manner was performed in 2 patients. There were 31 liver tumors treated with RFA. Blood loss were 110-900 mL (mean=320 mL). Operation time were 72-127 min (mean=107 min). Subcutaneous emphysema occurred in 1 patient, and pancreatic leakage in another patient. Nine patients developed ascites. one patient suffered from massive haemorrhage, and emergency operation was adopted to stop bleeding. This patient recovered well after operation. No death was found during the hospitalization. Conclusion:Combining RFA with LS for the treatment of liver cancer and hypersplenism is minimally invasive, safe, and feasible.

Objective To evaluate the clinical efficacy and safety of domestic Sirolimus-eluting stents (Firebird) and imported Zotalimus-eluting stents ( Resolute) in the treatment of patients with unprotected left main coronary artery disease ( ULMCA) . Methods We retrospectively enrolled 76 patients with ULMCA treated by percutaneous coronary intervention (PCI) under the guidance of IVUS in our hospital. According to the different stents used in the procedure, the patients were divided into two groups: Domestic Sirolimus-Eluting Stents group (Firebird group, n = 42) and Imported Zotarolimus-Eluting Stents group (Resolute group, n = 34) . We analyzed the baseline characteristics, coronary artery lesion characteristics, stenting strategies and any changes in left ventricular ejection fraction ( LVEF) in both groups and investigated the long-term clinical outcomes. Results There were no significant differences in the baseline characteristics, the SYNTAX scores of the coronary artery lesion and the rate of complete revascularization between the two groups. Compared with that in Firebird group, there were more cases involving the distal left main (79. 4% vs. 45. 2% , P ﹤ 0. 05) and more patients using two stents strategies (29. 4% vs. 7. 1% , P ﹤ 0. 05) in the Resolute group. The change in LVEF post-PCI had no difference between the two groups. The patients were followed up for a mean of (23. 3 ± 10. 7) months. During the follow-up period, the occurrence of MACCE had no significant difference between the two groups. In the Firebird group, there were one sudden cardiac death, one nonfatal myocardial infarction, one stroke and five patients with recurrence of angina pectoris. In the Resolute group there were one sudden cardiac death, one target lesion revascularization and four patients with recurrence of angina pectoris. Conclusions Compared with the imported Zotalimus-Eluting Stents, the domestic Sirolimus-Eluting Stents are safe and effective in the treatment of patients with unprotected left main lesions under the guidance of IVUS. The two kinds of stent showed similar long-term clinical outcomes.
