ObjectiveTo evaluate the laparoscopic procedure and therapeutic efficacy of retroperitoneal laparoscopic surgery for the treatment of adrenal ganglioneuroma.Methods6 patients [4 male and 2 female,32 to 59 (mean 41.3) years old],underwent retroperitoneal laparoscopic resection of adrenal ganglioneuroma. In this group, 2 patients with left adrenal ganglioneuroma, 4 patients with right adrenal ganglioneuroma. ResultsAll of the 6 cases was successfully performed uneventfully with retroperitoneal laparoscopic adrenalectomy. Pathologic studies confirmed there were 6 cases of adrenal ganglioneuroma. No case was transferred to open operation.The blood pressure remained stable during operation.Mean tumor size was (5.9±2.1) cm (tumor diameter 3.6-11.2 cm) Mean operative time was 120(90-210) min.Mean estimated blood loss was 160 (50-700) ml.Postoperative hospital stay ranged from 7 to 9 days.All the patients were cured without relapse during 4-32 month, follow-up. ConclusionsRetroperitoneal laparoscopic procedures for adrenal ganglioneuroma causes less traumatic;less operative blood loss;distinct image during operation;less postoperative discomfort;faster postoperative recovery and earlier return to daily activities and diet.Retroperitoneal laparoscopic procedure should be considered as the first choice for adrenal ganglioneuroma.

Objective To observe clinical efficacy of warm-promotion needling for the treatment of cold coagulation and blood stasis of primary dysmenorrhea.Methods Totally 120 patients with cold coagulation and blood stasis of primary dysmenorrhea were randomly divided into warm-promotion needling group (60 cases) and control group (60 cases). Warm-promotion needling group was treated with warm-promotion needling at Guanyuan (RN4), Sanyinjiao (SP6), Shiqizhui (EX-B8), and Diji (SP8), and cooperated with Ciliao (BL32), Hegu (LI4), and Taichong (LR3). Control group took same acupoints and applied uniform reforcing-reducing method. The two groups began treatment 5-7 d before menstruation, 1 times a day, for 7 times. The treatment was given 3 menstrual cycles. The visual analogue scale (VAS) and COX menstrual symptom scale (CMSS) were used to observe the pain degree at the end of 1, 2, 3 menstrual cycles. The clinical efficacy was evaluated 3 months after treatment.Results The scores of VAS and CMSS was obviously reduced in the two groups after the treatment compared with those before treatment (P<0.01). The synperiodic scores of VAS and CMSS in warm-promotion needling group was obviously lower than those in the control group (P<0.05). The total effective rate of warm-promotion needling group was 96.67% (58/60), and the control group was 73.33% (44/60), the difference was significant (P<0.05).Conclusion Warm- promotion needling can obviously relieve dysmenorrhea symptoms and shorten the time of pain of patients with cold coagulation and blood stasis of primary dysmenorrhea, which has affirmative clinical efficacy.

ObjectiveTo discuss the clinical diagnosis and treatment of multiple endocrine neoplasia ( MEN ) 2A, and report the mutation of the RET proto-oncogene in a pedigree of three patients with MEN 2A.MethodsBilateral adrenalectomy was performed on two of the three patients with hypertension and bilateral adrenal-conserving adrenal pheochromocytoma resection was performed on the other patient. All three patients were treated by total thyroidectomy and neck lymphadenectomy. Twelve family members were recruited to the study. Peripheral blood was collected and total genomic DNA was prepared for polymerase chain reaction (PCR). PCR products of exon 10 and exon 11 of the RET proto-oncogene were purified and a direct DNA sequence analysis was performed.ResultsThe pathological diagnosis of the specimens was bilateral adrenal pheochromocytoma and medullary thyroid carcinoma in all the three patients. There was no tumor recurrence or distant metastasis after 1.5 - 5 years of follow-up. A missense mutation of TGC (Cys)to CGC (Arg) at codon 634 in exon 11 of the RET proto-oncogene was detected in all three patients. Genetic screening identified two mutation carriers in the other members of this pedigree.ConclusionGenetic mutation screening and surgical intervention may be helpful to the members of high-risk families.

Objective To systematically assess the effectiveness and safety of acupuncture and moxibustion for treatment of rheumatoid arthritis. Methods Articles were searched from databases, i.e., CNKI, VIP, WanFang Data, CBM, Embase, and PubMed. Articles about RCT on acupuncture and moxibustion for rheumatoid arthritis and traditional medicine therapy were under meta-analysis. Results Totally 24 articles involving 2006 patients were included. The results of meta-analysis indicated that the overall effective rate of treatment in the group receiving acupuncture and moxibustion was higher than that in the drug group, with statistical significance [OR=2.73, 95%CI (2.18, 3.41), Z=8.78, P<0.000 01]. Sub-group analysis showed that:acupuncture and moxibustion showed statistical significance in decreasing serum RF levels compared with drug therapy [MD=-2.92, 95%CI (-5.60, -0.25), P<0.05]. Acupuncture and moxibustion showed statistical significance in decreasing serum ESR levels compared with drug therapy [MD=-2.99, 95%CI (-4.78, -1.21), P<0.05]. Acupuncture and moxibustion showed statistical significance in decreasing serum CPR levels compared with drug therapy [MD=-1.44, 95%CI (-2.44, -0.44), P <0.05]. Conclusion The overall effective rates of acupuncture and moxibustion for rheumatoid arthritis and the decreasing levels of RF, ESR, CRP are superior to drug therapy, but it still needs larger samples, multi-center, and high quality RCT to verify.

OBJECTIVETo compare the clinical efficacy differences between Zheng's gold hook, fishing acupuncture and electroacupuncture (EA) for lumbar disc herniation (LDH).

METHODSSixty patients of LDH were randomly allocated to a gold hook fishing acupuncture group and an EA group, 30 cases in each one. Lumbar Jiaji (EX-1 B 2), Yaoyangguan (GV 3), Shenshu (BL 23), Dachangshu (BL 25), Guanyuanshu (BL 26) and ashi points were selected in the gold hook fishing acupuncture group; after the needles were inserted, the manipulation of gold hook fishing acupuncture was applied at tendon junction points and ashi points. The identical acupoints were selected in the EA group and patients were treated with EA. The treatment was both given once a day; ten days of treatment were taken as one session, and totally 3 sessions were given. The clinical effective rate, visual analogue scale (VAS), low back pain score and Oswestry disability index (ODI) were used for efficacy evaluation.

RESULTSThe effective rate was 93.3% (28/30) in the gold hook fishing acupuncture group, which was superior to 86.7% (26/30) in the EA group (P < 0.05). The VAS, low back pain score and ODI were both significantly improved after treatment (all P < 0.05), which were more significant in the gold hook fishing acupuncture group (all P < 0.05).

CONCLUSIONZHENG's gold hook fishing acupuncture could effectively improve the symptoms and sings of LDH, reduce the disability index and improve the quality of life, which is superior to EA.
