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.

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.

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.

Methods A total of 102 patients with upper gastrointestinal bleeding were enrolled in the Department of Emergency Gastroenterology, Peking Binhai University Hospital from June 2014 to October 2016. The patients were randomly divided into observation group and control group, 51 cases in each group.The control group were only given omeprazole sodium, tranexamic acid injection,the observation group were given Agkistrodon hemocoagulase for injection on patients on the basis of the control group.After treatment, the clinical curative effect of two groups of patients were evaluated, the hospitalization days, the average hemostasis time, blood transfusion, bowel recovery time, abdominal pain relief time, the adverse reactions occurred of the two groups were observed.Results The total effective rate of the observation group was significantly higher than that of the control group (P< 0.05). The hemostasis time,the time of hospitalization and the average blood transfusion in the observation group were significantly lower than those in the control group (P<0.05). The recovery time of bowel and the time of pain relief in the observation group were significantly lower than in the control group (P<0.05). There was no significant difference in the incidence of adverse reactions between the observation group and the control group.Conclusion Comprehensive treatment of upper gastrointestinal bleeding with emergency internal medicine can significantly improve the clinical efficacy, shorten the time of hemostasis and recovery, and is worthy of clinical application.

With the development of business of manned spaceflight, the body damage of astronauts on the space en-vironment has received growing concern. Weight loss is the most important cause of various diseases, and the weightlessness muscle atrophy is one of urgent problems to be solved in aerospace medicine. Although there is no concept of weightlessness or weightlessness muscle atrophy in the theory of traditional Chinese medicine (TCM), TCM can grasp the pathogenesis of complex diseases, and provide important theoretical references for the prevention and management of weightlessness diseases, especially weightlessness muscle atrophy. In this paper, TCM Cognition of weightlessness and the pathogenesis of weightlessness muscle atrophy was studied by the sight of TCM theory of qi hoisting. The discussion was made from aspects of circulation of qi and blood, zang-fu function. This work is wished to be beneficial to apply the TCM theory in aerospace medicine.

Objective To evaluate right atrial function in patients with idiopathic dilated cardiomyopathy (IDCM) and ischemic cardiomyopathy (ICM) by using two-dimensional speckle tracking imaging (2D-STI).Methods Study population consisted of 31 patients with IDCM,30 with ICM and 30 healthy subjects.High frame rate two-dimensional images were recorded from the apical four chamber view.Right atrial global longitudinal strain (GLS) was measured using two-dimensional strain soft ware.Results Compared with the controls,left ventricular ejection fraction (LVEF),tricuspid annular plane systolic excursion (TAPSE),right ventricular fractional area change (RVFAC),right ventricular fractional shortening (RVFS) and tricuspid annular peak systolic velocity(S') decreased (P ＜0.05),while right ventricular myocardial performance index (MPI) increased in IDCM and ICM group.There were no significant differences for all above echocardiographic parameters between IDCM and ICM patients.Compared with the controls,right atrial GLS decreased significantly in patients with IDCM and ICM,even much lower in patients with IDCM (P ＜0.001).Conclusions Measurement of right atrial strain using 2DSTI could be used for the assessment of right atrial dysfunction in patients with ICDM and ICM.

Obje:ctive To establish an optimized method to isolate, culture and identify human umbilical cord mesenchymal stem cells (hUCMSCs) in vitro and induce their osteogenic and adipogenic differentiation. Methods The hUCMSCs were isolated from human umbilical cord by digestion with collagenase. After serial subcultivation in vitro, the stem cells were passaged. Morphologic appearance of hUCMSCs was observed under an optical microscope and atomic force microscope. The proliferation rate was measured by MTT assay. Cell cycle and surface antigens were measured by flow cytometry. The osteogenic and adipogenic differentiation was tested and evaluated by specific staining methods. Results The isolation of hUCMSCs by digestion with collagenase was efficient. After seeded for 24 hours, the adherent cells showed spindle shape and fibroblast cell-like shape and the size of hUCMSCs was homogeneous. The similar growth curves of passage 3 and 7 exhibited a great potential for proliferation. Flow cytometry analysis revealed that CD29, CD44 and CD105 were highly expressed on the surface of passages 3 cells, but the expression was negative for CD34, CD45 and HLA-DR. After culture in inducing medium, the cells were successfully induced into osteogenic and adipogenic lineages. These cells were highly positive for alkaline phosphate staining and also showed mineralization presented with von kossa staining after 4 weeks' culture induction of osteogenic differentiation. Furthermore, liquid vacuoles were detected by oil red O staining after 3 weeks' culture induction of adipogenic differentiation. Conclusion An in vitro method for isolation and purification of hUCMSCs from human umbilical cord has been established. The cultured cells were composed of only undifferentiated cells and their biological properties were stable. The hUCMSCs are expected to be a new type of stem cells of tissue engineering.

Objective To evaluate the left atrial(LA) and right atrial(RA) volumes and functions of fetuses in second and late trimester by using atrial volume tracking (AVT).Methods One hundred and seventy-six fetuses were enrolled in this study.Using AVT,the maximal and minimal volumes of RA and LA were measured from time-atrial volume tracking curves.RA and LA ejection fraction (RAEF and LAEF) derived from the value of atrial maximal volumes(LAVmax,RAVmax) subtracted atrial minimal volumes (LAVmin,RAVmin) and divided by LAVmax or RAVmax.Pearson correlation analysis was used to analyze the relationships between LAVmax,RAVmax,LAVmin,RAVmin,LAEF,RAEF and gestational ages.Results For all normal cases,the volumes of LA and RA were closely correlated with gestational weeks(r =0.80,0.85,0.83,0.82,P ＜0.001).The volume of LA was significantly smaller than that of RA (P ＜0.01).The RAEF and LAEF remained stable with advancing gestational age and there was no significantly difference between RAEF and LAEF (P ＞0.05).Conclusions This study establishes normal reference values for fetal RA and LA volumes during the second and third trimesters of pregnancy.The volumes of RA and LA are correlated with gestational weeks,and the volume of RA is bigger than that of LA.RAEF and LAEF are uncorrelated with gestational weeks,and there's no difference between RVEF and LAEF.

Objective: To compare clinical features and ultrasonic characteristics of hepatic angiomyolipoma (HAML), hepatic cavernous hemangioma (HCH) and hepatocellular carcinoma (HCC). Methods: Data of 40 patients with HAML confirmed by pathology who underwent CEUS were retrospectively analyzed. Clinical features, imaging characteristics of conventional ultrasound and CEUS were observed. Mean while, 40 patients with HCH and 40 patients with HCC were enrolled for comparison with HAML. Results: HAML mainly occurred in female (70.00%, 28/40), with an average age of (39.8±10.6) years. Distinctions of gender, age and hepatitis virus infection were statistically significant between HAML and HCC (all P<0.001), but no statistically difference was found between HAML and HCH (all P>0.05). HAML mostly presented as high echogenic lesions with clear boundaries and regular morphology on conventional ultrasound. There was no significant difference lesions'number, size, morphology nor blood supply between HAML and HCC (all P>0.05), but the distinctions of echo (χ2=8.93, P=0.008) and boundary (χ2=2.03, P=0.013) were statistically different. No statistical difference of number, size, border, echo, lesion morphology and blood supply was found between HAML and HCH (all P>0.05). On CEUS, 62.50% (25/40) of HAML showed "fast in and fast out" performance, but it subsided into iso-enhancement (t=-2.46, P=0.016) or hypo-enhancement (t=-5.35, P<0.001) later than HCC. There were significant differences of enhancement level in portal and delayed phases between HAML and HCH, as well as between HAML and HCC (all P<0.05), but there was no significant difference in arterial phase (both P>0.05). Conclusion: Combination of clinical features, conventional ultrasound and CEUS characteristics are helpful to distinguish HAML from HCH and HCC.
