BACKGROUND: Skinfold thickness instrument was used to analyze the distribution and development of subcutaneous fat. This method is simple, economic, and widely used. OBJECTIVE: To investigate the body fat development and age changes in female adults from Maonan nationality in Guangxi province. DESIGN, TIME AND SETTING: The cluster sampling investigation was performed at the Department of Anatomy, Basic College, Youjiang Medical College for Nationalities from September to October 2006. PARTICIPANTS: Using random sampling method, 533 healthy adult females of Maonan nationality and aged 25-75 years were selected from Huanjiang county of Guangxi province. They all live in Huanjiang count for over 10 years and their parents were also Maonan nationality. Taking five years were served as a group, totally 10 groups. METHODS: The indexes were measured and calculated by professionals according to Handbook of Human Measure. The equipment was modified skinfold thickness instrument. The database was set up in computer. MAIN OUTCOME MEASURES: Skinfold thickness of triceps brachii, anterior superior iliac spine, inferior angle of scapula and gastrocnemius. Four indexes were compared with other groups in China. RESULTS: The torso skinfold was thicker than limb ones. Skinfold thickness decreased with age after it came to the maximum. Compared with other minornationalities, the skinfold of Maonan adult females in Huanjiang of Guangxi province was thinner than Daur and Uzbek, but thicker than Bouyei nationality. CONCLUSION: The skinfold thickness of Chinese Maonan nationality in Guangxi province has a wavy change. It is thicker than Bouyei nationality and thinner than those in Dong nationality and Daur nationality and Uzbek nationality.

The instrument monitors respiratory rhythm of serious dangerous patients by temperatrature senser in nostril and electronic detective technique.The Principle is to input breath signal through temperature senser,which is attached to nasal cavity,and monitor will automaitcally give a alarm when frequencys of breath is under or over threshold.

Pain has been defined as an unpleasant sensory and emotional experience that is associated with actual or potential tissue damage,or is described in terms of such damage.Pain individual difference increases the complexity of clinical diagnosis and treatment of pain.China started relatively late on pain research and standardized pain treatment.It is necessary for further research on pain related to the clinical problem,the development of pain translational medicine,and improvement of clinical quality.The paper carries on the review.

Objective To investigate the Allelic and haplotype frequency distribution of seventeen short tandem repeat loci of Y chromosome in Heiyi Zhuang ethnic groups in Guangxi province.Methods Seventeen Y-STR loci,of which the template DNAs were extracted from blood samples of 184 unrelated male individuals in Heiyi Zhuang population,were amplified by using the AmpFlSTR YfilerTM.The PCR products were genotyped with ABI PRISM 310 genetic analyzer.Results The Gene diversity ranged from 0.4910 to 0.9727 at DYS456、DYS389Ⅰ、DYS390、DYS389Ⅱ、DYS458、DYS19、DYS385a\b、DYS393、DYS391、DYS439、DYS635、DYS392、Y-GATA-H4、DYS437、DYS438、DYS448.A total of 180 different haplotypes were observed,The haplotype diversity value calculated from all 17 loci was 0.99976.The significant difference of the allelic frequency distribution in Y-STR loci was found between Heiyi Zhuang population and other observed populations.Conclusion The 17th Y-STR loci in Heiyi Zhuang population of Guangxi province are highly affluent genetic polymorphic and can offer valuable genetic datas for paternity testing and paternal genetic lineages evolution.

Objective To investigate the effect of cold pressed Camelina Sativa oil (CPCO) on growth performance and lipid metabolism of hyperlipemia rats. Method The rats were divided into control group (Cont),high fat diet group (HFD),fish oil group (HFD+FO),low dose CPCO group (HFD+LCPCO) and high dose CPCO group (HFD+HCPCO). The latter 4 groups were fed high fat feed. Fo and CPCO were given by gavage. Total cholesterol (TC),triglyceride (TG),high density lipoprotein cholesterol (HDL-C) and HDL-C subtype levels in serum were determined at the end of 6w. The distribution of HDL-C particles was studied by agarose gel electrophoresis. Results HFD resulted typical hyperlipemia. Body weight,TC and TG level were significantly decreased,and HDL-C particles tended to be miniaturized and the HDL3 level increased by feeding Camelina Sativa oil as compared with HFD group. TC content in HFD+FO and HFD+HCPCO group was decreased 46.06% and 30.60% respectively. TG content in these two groups was decreased 25.81% and 22.72% respectively as compared with HFD group. Conclusion Chinese Camelina Sativa oil which contained high level of ?-linolenic acid(ALA)could prevent and cure hyperlipidemia by regulating blood lipid metabolism and protecting hepatic function.

Objective To explore the role of spinal cord p300 in neuropathic pain induced by chronic constriction nerve injury (CCI) in rats.Methods Thirty two Sprague-Dawley (SD) rats were randomly divided into sham and CCI groups,14 days after surgery,immuno-fluorescence staining and Western blot were used to detect distribution and expression of p300 protein.After rats were successfully implanted with an intrathecal catheter and accepted CCI surgery,another 24 rats were randomly divided into three groups (n =8):dimethyl sulfoxide (DMSO) group,p300 acetyltransferase inhibitor C646 group,and control C37 group.Each rat were administered through the intrathecal catheter from day 7 to 14 and mechanical withdraw threshold were tested.Results (1) The p300 positive cells were detected mainly in neurons,and p300 protein in spinal cord of CCI group were significantly higher than sham group (P ＜0.05).(2) C646 alleviated significantly neuropathic pain in rats,without significant changes in pain threshold after injection of C37 and DMSO.Conclusions The p300 protein in spinal cord was involved in the development of neuropathic pain in rats,the mechanism may be referred to its acetyltransferase activity.

Objective To investigate the clinical,endoscopic and pathologic features in the differential diagnosis between Crohn' s disease (CD) and intestinal tuberculosis (ITB).Methods The complete clinical data of 107 patients with CD and 69 patients with ITB in our hospital from January 2011 to January 2012 were retrospectively analyzed.The diagnostic value of the clinical and endoscopic scoring system was evaluated.Results CD occurred mainly in male.The salient features of CD included long duration of disease high incidence of colectomy.Comparing with patients with ITB,patients with CD have more cases of diarrhea,hematochezia,abdominal mass,intestinal obstruction,intestinal hemorrhage,perianal lesions,and extraintestinal manifestations (all P ＜ 0.05).It's more frequent to have positive results of anti-Saccharomyces cerevisiae antibody (ASCA),perinuclear antineutrophil cytoplasmic antibody (pANCA) and fecal occult blood in CD patients,as well as low albumin,high C-reactive protein (CRP),elevated platelet count and hematocrit (P ＜ 0.05 or P ＜ 0.01).The salient features of ITB included low fever,night sweats,active parenteral tuberculosis,increased erythrocyte sedimentation rate (ESR),chest X-ray abnormalities,the positive PPD (purified protein derivatives tuberculin) and T-SPOT (P ＜ 0.05 or P ＜0.01).Based on the imaging,CD often involved the small intestine,such as the intestinal stricture and abdominal abscess (P ＜ 0.05),while mesenteric lymphadenopathy was more common in ITB (P ＜ 0.05).The endoscopic examination showed that some patterns of disease involvement such as fissure-shape ulcer [41.12％ (44/107) vs 5.80％ (4/69)],cobblestone sign [15.89％ (17/107) vs 4.35％ (3/69)],lesions over four segment [24.30％ (26/107) vs 7.25％ (5/69)],rectum involvement [17.76％ (19/107) vs 5.80％ (4/69)],ileocecal valve stenosis [21.50％ (23/107) vs 8.70％ (6/69)] and mucosal bridge [5.61％ (6/107) vs 0(0/69)] were more frequent in CD patients than those in ITB patients(P ＜ 0.01 or P ＜0.05).However circular ulcers[37.68％ (26/69) vs 9.35％ (10/107)],rat-bite-like ulcers[24.64％ (17/69) vs 12.15％ (13/107)],persistent open ileocecal valves [39.13％ (27/69) vs 19.63％ (21/107)],tuberous and polypoid lesions [36.23％ (25/69) vs 20.56％ (22/107),37.68％ (26/69) vs 22.43％ (24/107)] were more common in ITB (P ＜ 0.01 or P ＜ 0.05).In terms of pathological findings,certain characteristic features such as transmural inflammation [5.61％ (6/107) vs 0 (0/69)],fissure-liked ulcers [14.02％ (15/107) vs 4.35％ (3/69)],non-caseous granulomas [5.61％ (6/107) vs 0(0/69)],lymphoid hyperplasia [16.82％ (18/107) vs 5.80％ (4/69)] and crypt abscess [9.35％ (10/107) vs 1.45％ (1/69)] were more common in CD than those in ITB(P ＜ 0.05).According to the clinical and endoscopic scoring system,the positive diagnostic rate of CD was 50.47 ％ (54/107)and of ITB was 66.67 ％ (46/69) (P ＜ 0.05).Conclusions The differential diagnosis between CD and ITB should be considered carefully based on clinical,endoscopic,pathological characteristics.The clinical and endoscopic scoring system may contribute to distinguish CD and ITB.

Objective To evaluate the changes in the expression of acetylated histone H3 (Ac-H3) and deacetylase silent information regulator 1 (SIRT1) in dorsal root ganglions in a rat model of negative phenotype neuropathic pain.Methods Forty-eight male Sprague-Dawley rats,weighing 250-300 g,were randomly divided into 2 groups (n =24 each):sham operation group (group S) and C-fiber dysfunction group (group CFD).The rats were anesthetized with 10％ chloral hydrate 3 ml/kg.C-fiber dysfunction was induced by exposing sciatic nerve to 8％ capsaicin for 30 min in group CFD.The thermal withdrawal latency (TWL) and mechanical withdrawal threshold (MWT) were measured before and on 1,3,7 and 14 days after CFD.Six rats were then sacrificed at each time and the lumbar segments (L5) of the dorsal root ganglions were removed for detection of SIRT1 mRNA expression (by RT-PCR) and Ac-H3 and SIRT1 protein expression (by Western blot).Results Compared with group S,TWL was significantly increased at 1,3,7 and 14 days after CFD,SIRT1 mRNA and protein expression was up-regulated and Ac-H3 expression was down-regulated at 3,7 and 14 days after CFD (P ＜ 0.05),while no significant change was found in MWT at each time point in group CFD (P ＞ 0.05).Conclusion The mechanism of negative phenotype neuropathic pain is related to up-regulation of deacetylase SIRT1 expression and decreased acetylation of histone H3 in rat dorsal root ganglions.

Objective To study the type variation of microglial activation in spinal dorsal horn of rats after sciatic nerve injury.Methods Healthy adult male Sprague-Dawley rats were randomly divided into the control and experimental groups, 24 rats in each group.The experimental group underwent ligation of sciatic nerve trunk to generate nerve injury in the rats.The pain behavior in the rats was measured at the 1th, 7th and 14th postoperative days, and the changes of microglial activation in the rat lumbar spinal cord dorsal horn was detected by immunofluorescence staining.qRT-PCR assay was used to validate the activation trends of M1 and M2 types of microglia cells.Results No significant changes were found in the microglial cells in the spinal cord dorsal horn of rats in the sham-operation group during 14 days after operation.In the sciatic nerve ligation group at 1 day after operation, no significant change was observed in the number of microglial cells, but the expression of marker of M1 microglia was significantly increased.At 7 and 14 days after operation, the number of microglial cells and the expression of M1 microglia marker in the spinal cord dorsal horn were increased significantly.Conclusions Microglia activation in the spinal dorsal horn starts at the first day after sciatic nerve injury, and lasts at least for two weeks after the operation.M1 microglia activation dominates during this period.

OBJECTIVE: To investigate the factors affecting shoulder joint functions following artificial humeral head replacement. METHODS: A total of 22 patients with complex fracture of proximal humerus, managed by humeral head replacement in Changhai Hospital of The Second Military Medical University from June 2006 to December 2008 were collected, including 12 males and 10 females, with average age of 67 years (52-86 years). During the procedure, soft tissue damage was minimized, the bone of the tuberosity was reserved as much as possible, appropriate matching size of humerus head prosthesis was selected, and early staging functional rehabilitation was performed. Neer's scoring system was used to evaluate the treatment results after replacement. RESULTS: The 22 patients were followed up for 10-30 months, mean 22.6 months. The shoulder joint functions of 14 cases were recovered more quickly through early post-operative staging rehabilitation, No shoulder joint unstable and stiff occurred. The shoulder joint functions of 8 cases were recovered slowly as they complained pain and did not perform early physical therapy after surgery, shoulder joint of 2 cases presented little unstable and 1 case presented stiff. Only 4 cases of all complained occasionally slight shoulder pain, but could continue daily work. The mean movement ranges of shoulder were as follow: mean flexion for 96°(80°-103°), mean extension for 38° (32°-45°), mean abduction for 86°(80°-110°), mean adduction for 31°(30°-35°), mean external rotation for 32°(30°-37°) and internal rotation for 42° (10°-75°). No vasculardamage, nerve damage, lessening prosthesis or prosthesis dislocation was found in all cases. Based on Neer's scoring system, 5 cases were rated as excellent, 11 as good and 4 as fair, with excellent rate of 82% and case satisfaction rate of 87%. CONCLUSION: In order to recover maximally the shoulder joint functions for post-artificial humeral head replacement, we must try our best to avoid soft tissue damage, reserve the bone of the tuberosity, select appropriate humerus head prosthesis, perform early post-operative staging rehabilitation, as well as maintain a normal retroversion of the prosthesis.
