Objective To explore the safety and effectiveness of enhanced recovery after surgery (ERAS) after laparoscopic radical gastrectomy for gastric cancer.Methods From January 2014 to December 2015,167 gastric cancer patients undergoing laparoscopic radical gastrectomy with D2 lymphadenectomy were divided into the enhanced recovery after surgery group (ERASG,67 cases) and 102 cases the conventional surgery group (CSG,102 cases).The general status,tumor stage,postoperative recovery,complications,hospitalization time and 30 day readmission were compared between ERASG and CSG.Results The first exhaust time in ERASG and CSG were (2.6 ± 1.1) days and (3.8 ± 1.3) days (t =-6.494,P ＜ 0.01).Statistical analysis showed that there was no significant difference in the postoperative hospitalization time,30 day readmission rate,complications,anastomotic leakage,wound infection,pneumonia,gastric retention and intestinal obstruction between of ERASG and CSG (all P ＞ 0.05).Conclusions Patients in ERASG have quicker postoperative recovery than those in CSG,with similar postoperative complications.

[Objective] To evaluate the clinical curative effect of a combined protocol using Chinese herbal medicine and acupuncture for chronic gastritis.[Methods] 23 patients used the Chinese medicine only(group 1)and 65 patients received the combined protocol(2).Clinical symptoms and gastroscopic findings before and after treatment were recorded and analyzed.[Results] The clinical symptoms improved greatly in 15 of the group 1,with an overall curative rate 65%,and in 62 of the group 2 with an overall curative rate 95%.The difference between the 2 groups was significant.[Conclusion] The combined use of Chinese medicine and the needle medicine is preferable to single use of Chinese medicine for chronic gastritis.

Objective To evaluate the value of color Doppler flow imaging(CDFI) in the diagnosis of congenital coronary artery fistula (CAF).Methods Thirteen consecutive patients ranging in age from 8 to 68 years underwent conventional transthoracic echocardiography,which depicts their origin, course, and drainage site. Results Right CAFs were detected in 8 patients: four of them had drainages to the left ventricle, two to the main pulmonary artery, one to the right ventricle(RV) and the other to the right atrium(RA). CAFs arising from the left coronary artery were noted in five patients: three of them had drainages to the main pulmonary, and the other two to the RA and RV respectively. The origin and the course were precisely defined and the drainage site was clearly depicted in all thinteen patients. The diagnosis of the thirteen patients was confirmed by coronary angiography, and eight of them received surgical treatment. Conclusions CDFI offers a simple, useful and reliable technique in diagnosis of CAF.

Objective: To explore the feasibility of the application of small specimens as alternatives of gross specimens to detect EGFR (epidermal growth factor receptor) mutation in NSCLC (non-small cell lung cancer) by ARMS (amplification refractory mutation system). Methods: Biopsy specimens from 181 cases of NSCLC were collected, in which 157 were small specimens (including specimens acquired through CT-guided percutaneous lung biopsy, endobronchial ultrasound-guided transbronchial needle aspiration, lymph node biopsy, bronchoscopic biopsy and aspiration of pleural effusion) and 24 were gross specimens. QIAGEN DNA extraction kit was used to extract DNAs from NSCLC specimens. Then AmoyDx EGFR Mutation Test Kit - a highly sensitive real-time PCR-based test was used to detect EGFR mutations. The detection rates of EGFR mutations in small specimens and gross specimens were compared by Chi-square test or Fisher's exact test. Results: The total EGFR mutation detection rate of all biopsy specimens was 39.8% (72/181). The detection rates of small specimens and gross specimens were 38.9% and 45.8%, respectively (P = 0.515). Furthermore, EGFR mutation frequencies were significantly higher in non-smokers (P = 0.033) and in patients with adenocarcinoma (P < 0.001). Conclusion: A relatively high detection rate of EGFR mutation in NSCLC small specimens can be obtained through ARMS. For patients with advanced NSCLC whose gross specimens cannot be easily obtained, the alternative small specimens can be used in clinical EGFR mutation detection. Copyright © 2012 by TUMOR.

Objective:To obverse the therapeutic effect of superficial needling with different frequencies for intractable facial paralysis. Methods: A total of 120 patients with intractable peripheral facial paralysis were allocated into a superficial needling with high frequency group (150 times/min), a moderate frequency group (100 times/min) and a low frequency group (50 times/min) according to the random number table method. The Toronto facial grading system (TFGS) was used to evaluate facial nerve functions before treatment and after 2 weeks and 4 weeks of treatment respectively. The electromyography (EMG) test of the mandibular branch of facial nerve was used to compare the motor nerve conduction velocity (MCV), sensory nerve conduction velocity (SCV) and monophasic action potential (MAP) among different groups, and was done before treatment and after 4 weeks of treatment. The clinical efficacy was also compared. Results: After 2 weeks and 4 weeks of treatment, the changes of TFGS scores in the three groups all showed statistical significance (all P＜0.05), and the TFGS score in the low frequency group was substantially higher than that in the other two groups. After treatment, the changes of the MCV and SCV in the three groups all showed statistical significance (all P＜0.05), and the results in the low frequency group were higher than those in the other two groups; the change of MAP in the three groups showed no statistical significance (P＞0.05). The total effective rate was 65.0%, 80.0% and 95.0% in the high frequency group, moderate frequency group and low frequency group respectively, and the between-group differences showed statistical significance (P＜0.05). Conclusion: Compared with the superficial needling with high and moderate frequencies, superficial needling with low frequency can produce more significant clinical efficacy for intractable facial paralysis.
