OBJECTIVETo observe clinical therapeutic effect of fuzhong (supporting the middle-jiao) manipulation of tuina for infantile anorexia.

METHODSEighty-one children with anorexia were treated with fuzhong manipulation, including abdominal kneading, acupressure at Zhongwan (CV 12), Lanmen (Extra), Tianshu (ST 25), Zusanli (ST 36), Sanyinjiao (SP 6), spine pinching, warm moxibustion and warm scraping with supporting-yang cupping, three times a week, six times as a session. Onset time, therapeutic effect and TCM symptom scores before and after treatment were observed after two sessions and differences of therapeutic effect among different patterns were compared.

RESULTSSeventy-two children had the effect in one session while 41 children had the effect within half of a session. 38 cases were clinically cured, 15 cases were markedly effective, 23 cases were effective and 5 cases were failed. The total effective rate was 93.8%. Compared with before treatment, TCM symptom scores, including appetite, food intake, complexion and defecation, were all obviously improved after treatment (all P < 0.001). The clinical cured rate was 45.2% (19/42) in the pattern of dysfunction of spleen in transportation, 45.8% (11/24) in the pattern of qi deficiency of spleen and stomach, 50.0% (4/8) in the pattern of yin deficiency of spleen and stomach, 57.1% (4/7) in the pattern of liver sufficiency and spleen insufficiency, which had no obvious differences among different patterns (all P > 0.05).

CONCLUSIONThe fuzhong manipulation of tuina has quick onset time and satisfied clinical therapeutic effect, which could obviously improve symptoms and is fit for different patterns of infantile anorexia.

AIM: To study the effect of tissue kallikrein gene (HK) treatment on blood pressure in type 2 diabetic rats and its mechanism. METHODS: Male Wistar rats were injected with low dose streptozotocin and fed with diets enriched in fat and sugar to form type 2 diabetic model. Recombinant adeno-associated viral vectors (rAAV)-mediated HK gene (HK group) or LacZ gene (LacZ group) was introduced to the diabetic rats. The systolic blood pressure was measured every 2 weeks. The acetylcholine (Ach)-dependent vasodilation response, the synthesis of nitric oxide (NO), the expression of endothelin-1 (ET-1) and endothelin-A receptor (ET_A-R) in the aorta were detected. RESULTS: (1) Systolic blood pressure was significantly higher in diabetic rats than that in normal control rats. In HK group, systolic blood pressure was significantly reduced within 2 weeks after injection with rAAV?HK, reached near normal levels at 4 weeks and kept until the experiments ended (16 weeks). (2) In LacZ group, Ach-dependent vasodilation response of isolated aorta was markedly decreased than that in HK group (P

Objective To study the characteristics of life events, coping styles and social supports in anxiety disorders patients. Methods 50 patients with generalized anxiety disorders (GAD), 44 patients with obsessivecompulsive disorders (OCD),23 patients with social anxiety disorders (SAD) and 99 healthy people were assessed by life event scale(LES),simplified coping style questionnaire(SCSQ) and social support rating scale (SSRS). Results Compared with healthy people, patients with GAD, OCD and SAD were all had higher scores of total life events (GAD 22.46±18.44;OCD 23.68±28.31;SAD 17.22±14.97;Healthy People 6.64±9.71)( F =14.216,P =0.000) and negative life events(GAD 18.76±17.99;OCD 20.02±24.98;SAD 12.00±13.16;Healthy People 4.56±7.51)( F =14.391,P =0.000).All patients were apt to choose positive styles less( F =16.505,P =0.000) and got less social supports totally ( F =26.506,P =0.000). The objective social supports( F =7.494,P =0.000)and subjective social supports ( F =26.985,P =0.000) were less and the utilization of social supports was lower ( F =13.931,P =0.000) in patients.Conclusions 1. Anxiety disorders patients often experience more or more serious life events, especially negative life events, are more likely to choose negative coping styles, and get less social supports. 2. Anxiety disorders may be related with people's characteristics of life events, coping styles and social supports.

BACKGROUND:Mechanical stimulation triggers a muscle tissue remodeling, during which, myoblast process is a multi-stage development process. Many signals in extracellular matrix are involved in myoblast process, and mechanical signals are considered as important external factors for muscle formation and regeneration.
Numerous studies concerning cyclic tensile stress effects on myoblast proliferation and apoptosis have been reported, but the specific mechanism underlying the mechanical stimulation in muscle formation is stil unclear. OBJECTIVE:To study the effects of cyclic stretch on proliferation of C2C12 myoblasts and its mechanism.
METHODS:C2C12 myoblasts were cultured in vitro under 10%cyclic stretch for 6, 12 and 24 hours.
RESULTS AND CONCLUSION:The results of 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide assay showed that with the time of cyclic stretch, the proliferation of C2C12 myoblasts and the rate of S-phase fraction were gradual y increased and peaked at 12 hours (P<0.05), and then decreased. Western blot assay showed that the expression of nuclear transcription factorκB protein was decreased with time, which was inversely correlated to the proliferation of C2C12 myoblasts, but increased at 24 hours under the cyclic stretch. These findings indicate that the cyclic stretch can induce C2C12 myoblasts proliferation and alter the cellcycle. Nuclear transcription factorκB may be involved in this process.

Objective To investigate the mechanism of cross resistant inducibility of ciprofloxacin and imipenem which led to cross resistance in Pseudomonas aeruginosa in vivo. Methods Cross resistant mutant strains were selected and induced with clinical isolates of P.aeruginosa PA5 susceptible to ciprofloxacin and imipenem by experiment of murine peritonitis. Mutation of DNA gyrase gene, drug uptake and membrance proteins of P.aeruginosa PA5 and its mutants resistant to ciprofloxacin and imipenem were examined. Results Both ciprofloxacin and imipenem could induce resistant strain of P.aeruginosa in experimental murine peritonitis, the cross resistance rates after ciprofloxacin and imipenem challenge were 3.8% and 0.98% respectively. The results of PCR SSCP showed that 3 of six cross resistant of P.aeruginosa strains had gyrA gene mutation. Electrophoresis of outer and inner membrane proteins did not exist any difference between cross resistant strains and their parent strain PA5. Fluorometric assay for ciprofloxacin uptake by bacterial cells indicated that the accumulation of ciprofloxacin in all cross resistant variants decreased to 1/2～1/3 compared with that of PA5. After chanllenge with CCCP, the drug uptake in cross resistance mutants increased to the same level as in PA5. Conclusions The results show that cross resistant strains of P. aeruginosa could be selected and induced in vivo. Active drug efflux is the major factor contributing to the cross resistance of P. aeruginosa to both quinolone and imipenem.

Objective To study the symptom dimensions of Chinese patients with obsessive-compulsive disorder(OCD). Methods Symptom checklist in expert versions of Dimensional Yale-Brown Obsessive-Compul-sive Scale (DY-BOCS) was used to assess the symptom dimensions of 139 OCD patients. Results Nearly half of the patients had one dimension (50.4%). The frequency of patients with two or three dimensions was 24.5% and 14.4%. Patients with four to seven dimensions were very few and the frequency were 5.8% ,3.6% ,0.7% and 0.7% ,respectively. The most common symptom dimensions were symmetry (67.6%), contamination (43.2%) and aggressive (31.7%). The frequency of patients with miscellaneous, somatic, sex and religious, hoarding di-mension were 18.7%, 11.5% , 10.8% ,8.6% ,respectively. The frequency of male patients with symmetry dimen-sion was higher than that of the female patients(75.8%/52.1%, P<0.01), and the frequency of female patients with contamination dimension was higher than that of male patients (56.3%/36.3%, P<0.05). There were no differences in other dimensions between male and female patients. The early-onset patients had a greater of symp-toms in the symmetry dimension than late-onset patients and there were no differences between these two groups in other dimensions (77.6% vs 60.5%, P<0.05 ) . Conclusion Preliminary data suggest that the symptom di-mension approach may aid in the identification of subtype of OCD.

Objective To investigate the feasibility of aortic and mitral valves replacement under video-assisted thoracoscope.Methods The subjects included 16 dogs(Experimental Group) and a clinical volunteer(Clinical Group).The procedure was performed under extracorporeal circulation with femoral artery and vein intubation.An incision 4~5 cm in length and two 1.5 cm ports were made in the right chest wall.The superior and inferior vena cava were cross-clamped by a self-made clamp and the myocardium was protected by cold cardioplegic coronary perfusion.Artificial mechanical aortic and mitral valves were intermittently sutured.Results In the Experimental Group: the time of extracorporeal circulation was 104~196 min(143.2?46.5 min) and the ascending aorta cross-clamped time was 58~128 min(82.4?26.1 min).Autopsy findings showed satisfactory valve suture fixation,without thread loosing or paravalvular rupture.In the Clinical Group: the time of extracorporeal circulation was 157 min,the ascending aorta cross-clamped time was 112 min,the time of mechanical ventilation was 10 h,and the drainage volume,150 ml.The patient was discharged from hospital on the 10 postoperative day.Follow-up observations for 9 months found no paravalvular leakage or other complications.Echocardiography showed normal prosthetic valve movement.Conclusions Video-assisted thoracoscopic aortic and mitral valves replacement is technically feasible.

We describe a 44-year old man who suffered an isolated external auditory canal granulocytic sarcoma in remission of acute myeloid leukemia. The patient confirmed acute promyelocytic leukemia three years ago and the disease was in remission after treatment. Two months ago he presented pain and hearing loss in the left ear and the symptom developed gradually. At otoscopic examination a tumoral lesion was noted in the external auditory canal and computerized tomography scan showed a mass in the left external acoustic meatus without bone erosion.
