Chinese Acupuncture & Moxibustion 2016;36(2):124-128
OBJECTIVETo compare the difference among the combined method of oral administration of forlaxand acupoint embedding therapy, the simple acupoint embedding therapy and the simple oral administration of for-lax in the clinical efficacy on diabetic constipation.
METHODSOne hundred and fifty patients were randomized intoa comprehensive group, an acupoint embedding group and a forlax group, 50 cases in each one. In the acupointembedding group, the embedding therapy was applied to bilateral Tianshu (ST 25), Daheng (SP 15), Shangjuxu(ST 37) and Dachangshu (BL 25), once a week. In the forlax group, forlax (polyethylene glycol) was prescribedfor oral administration, once a day, 10 g each time. In the comprehensive group, the acupoint embedding therapyand forlax were combined and the methods were the same as the first two groups. The treatment for 4 weeks wasas one session, and 2 sessions were required in the three groups. Separately, in 4 weeks, 8 weeks of treatment and2 months after treatment, the constipation symptom scores were compared among the three groups. At the end of2 sessions of treatment, the clinical efficacy and adverse reactions were compared among the three groups. In2 months after treatment, the recurrence rate was compared among the three groups.
RESULTSThe total effectiverate was 98. 0% (49/50) in the comprehensive group, better than 86. 0% (43/50) in the acupoint embeddinggroup and 78. 0% (11/50) in the forlax group (both P<0. 01). In the 4 weeks and 8 weeks of treatment, the con-stipation symptom scores were reduced significantly as compared with those before treatment in the three groups(all P<0. 05). The results in the comprehensive group were lower than those in the other two groups (all P<0. 05). In the 4 weeks of treatment, the scores were not different significantly between the acupoint embedding group and the forlax group (P>0.05). In 8 weeks of treatment and 2 months after treatment, the scores in the acupoint embedding group were better tan those in the forlax group (all p<0.05). There were 2 cases of drug adverse reaction in the comprehensive group, 6 cases in the forlax group and 0 case in the acupoint embedding group. The recurrence rate was 8.1% (4/49) in the comprehensive group, lower than 32.6% (14/43) in the acupoint embedding group and 59.0% (23/39) in the forlax group (both P<0.01).
CONCLUSIONthe combined therapy of acupoint embedding and forlax achieves the better clinical efficacy on diabetic constipation and constipation symptom scores as compared with the simple acupoint embedding therapy and the oral administration of forlax the short-term efficacy of the simple acupoint embedding therapy is not different significantly from the simple forlax medication, but the long-term efficacy and safety are better than those of simple forlax medicaiton.

8.Cone-beam computed tomography analysis of the canal shaping ability with ProTaper Universal, ProTaper Next and M3 in preparation of curved root canals
Tianjin Medical Journal 2017;45(3):289-293
Objective To evaluate the shaping ability of ProTaper Universal (PU), ProTaper Next (PN) and M3 in preparation of curved root canals by CBCT (cone-beam computed tomography). Methods Sixty extracted maxillary first premolars were divided into two groups according to the canal curvature:10°-25° group and 26°-75°group. Then, each group was divided into PU group, PN group and M3 group and prepared with three instruments respectively. Canals were scanned by CBCT scanner before and after preparation. The efficacy of canal preparation was analyzed. The width of dentine removed was measured at three points (2 mm, 5 mm and 8 mm to root tip). The apical transportation indexes and the centring ratio values were recorded. Results PN group and M3 group needed less time in preparation and showed more efficiency than those of PU group in 26°-75° groups. One of root canals in PU group appeared deformation, neither PN group nor M3 group appeared deformation after 5 root canal preparations in average. None instrument was broken in three groups. PU group removed more materials at internal walls than PN group and M3 group at internal walls of root canals in 5 mm from the apex. There was no difference in the offset of the external walls of root canals. Compared with the offset of the internal and external walls of root canals in 2 mm from the apex, the apical transportations prepared by the PN group were less than those of M3 group and PU group in 26°-75° groups. Compared with the offset of the internal and external walls of root canals in 5 mm from the apex, the apical transportations prepared by the PN group and M3 group were less than those of PU group, and their centring ratio values were greater than those of PU group in 26°-75°groups. Conclusion ProTaper Next and M3 tested in this study are effective and time-saving in shaping curved root canals. The results indicate that both ProTaper Next and M 3are comparable to optimally enlarge root canal.
9.Diagnosis and surgical treatment of xanthogranulomatous cholecystitis
Journal of Clinical Hepatology 2017;33(2):247-252
Xanthogranulomatous cholecystitis (XGC) is a rare type of chronic cholecystitis characterized by severe proliferative fibrosis with infihration of macrophages and foamy cells in the gallbladder wall.Since XGC and gallbladder carcinoma have similar clinical manifestations and radiological features,XGC is often misdiagnosed as gallbladder carcinoma in clinical practice,which leads to unnecessary extensive surgical resection and has an adverse effect on patients.At present,the preoperative diagnosis of XGC is still based on imaging results (ultrasound,computed tomography,and magnetic resonance imaging),and a definite diagnosis of this disease relies on intraoperative frozen biopsy or postoperative pathological examination.Meanwhile,XGC should be differentiated from gallbladder adenomyomatosis,gallbladder carcinoma,and gallbladder actinomycosis.Laparotomy or laparoscopic cholecystectomy is the major method for the treatment of XGC,but laparoscopic cholecystectomy is associated with a longer time of operation,more complications,and a higher rate of conversion to laparotomy.Therefore,surgeons are facing difficulties in preoperative diagnosis and intraoperative decision-making process of XGC.
