Objective To Analysis the physical fitness participation of 1243 community residents and to provide the scientific basis for developing intervention strategies. Methods The study was based on data of Physical Activity Questionnaire collected in Nutrition and Health Survey 2006 in Putuo, Shanghai. 1 243 subjects aged 6 years and above were involved. Results 43.8% of community residents had participated in physical exercise. Participation ratio was 41.4% in male, lower than that in female (45.8%). Participation ratios among aged 6yr～, 18yr～, 45yr～, 60yr～ were 48.1%, 25.2%, 22.0%, 64.9% in male and 40.8%, 22.5%, 40.1%, 67.1% in female. Participation ratios among age groups were significantly different (P=0.000). Proportion for frequent exercise of all age groups were 25.0%, 11.9%, 19.7%, 64.9% for male and 21.1%, 15.0%, 37.4%, 66.3% for female. There were difference among age groups (P= 0.000). Conclusion Specific intervention measures should be developed for different kind of people.

ObjectiveTo compare the clinical effect of posterior circumferential fusion with versus without intertransverse process fusion on lumbar instability in aged patients. MethodsThe elderly with lumbar instability were treated with the posterior instrumented circumferential fusion technique in 80 cases. Among 58 patients followed up for at least 2 years, 28 cases (group A)underwent posterior circumferential fusion with intertransverse process, while 30 cases (group B)without intertransverse process. X-ray examination was used before and 1, 3, 6, 12 and 24 months after operation to evaluate the fusion condition of the bone graft, and visul analogue scale (VAS) and Oswestry disability index (ODI) questionnaire were applied to assess the pain of center back and leg,and the conventional activity.ResultsThe operation time and blood loss were more in group A[(185.3±56.6) min and (376.3±92.9) m1] than in group B [(146.4±46.3) min and (234.3±64.5)ml (t=12.37, 37.49, P＜0.01)]. All the 58 cases were followed for at least 2 years. The 27 cases (96.4％) of group A and 28 cases (93.3％) of group B got bone fusion (x2 =0.004, P＞0.05).There were marked differences in the VAS of center back at 1 and 3 months after operation between the 2 groups (t=3.178, 2.158, both P＜0.05), while no difference at the other 3 time point. VAS about the leg pain and the ODI showed no differences between group A and B after operation (all P＞0.05). ConclusionsFor the lumbar instability in the elderly, the posterior circumferential fusion with or without intertransverse process fusion can achieve a similar high rate of fusion and satisfactory clinical results,andtheposteriorcircumferentialfusionwithoutintertranaverseprocess is recommended for less trauma.

Objective To study the clinical and pathologic features of chromphobe renal cell carcinoma (ChRCC) and to evaluate the conventional pathologic prognostic parameters in prognosis.Methods Seventy-five cases (42 males and 33 females) with pathological confirmed ChRCC (36 on the left and 39 on the right kidney) after nephrectomy during 1998 to 2009 were retrospectively analyzed. Patient's age ranged from 25 to 74 years, with a mean age of 56 years. Evaluation of conventional prognostic parameters was carried out. Kaplan-Meier survival curve was used to study the survival relationship. Results The mean tumor diameter was 7.3 cm. The majority of tumor macroscopic surface color was gray and yellow or gray and red. The majority of tumor cells were big polygon chromphobe cell or small round eosinophils. The TNM stages of these ChRCC were as follows: 30 cases in T1N0M0, 1 in T1N0M1, 26 in T2N0M0, 1 in T2N0M1, 11 in T3N0M0, 3 in T3N0M1, 1 in T3 N1 M0, 1 in T4 N0 M1 and 1 in T4 N1 M1. The pathologic grade of ChRCC was G1 in 3 cases, G2 in 24cases, G3 in 46 cases and G4 in 2 cases. All the 75 cases were followed up for 9 to 93 months (mean 44months), 7 patients died and others were alive without recurrence and metastasis. 3-year and 5-year survival rates were 93.3% and 90. 7%, respectively. The univariable analysis showed that tumor size (P=0. 028), TNM stage (P＜0. 001) were associated with tumor progression. The multivariable Cox regression model revealed that TNM stage was an independent predictor of aggressive ChRCC. Conclusions The ChRCC tumors are generally larger than other types of RCC and with a favorable prognosis. Fuhrman nuclear grade is not suitable for ChRCC. TNM stage is an independent predictor of aggressive ChRCC.

Objective To analyze the MRI characters of Charcot joint, and to evaluate the diagnostic value of X-ray, CT, and MRI on Charcot joint. Methods Eight patients with 8 Charcot joints underwent X-ray, CT, and MR examinations. 6 of them had syringomyelia, 1 patient had injury of the spinal cord, and 1 case had diabetes. All 8 patients had sensory reduction or deficit in the sick extremities. Results There were two types of Charcot joint, hypertrophic and atrophic. Radiographic and CT features of hypertrophic joint (n=3) showed hyperostotic osteosclerosis and mammoth osteophytes in the sick bones, periarticular ossification,and articular disorganization. Radiographic and CT features of atrophic joint (n=5) showed extensive bone resorption (destruction), periarticular debris, and articular disorganization. Main MRI features of Charcot joint included hydrarthrosis within joint capsule, thickened, loose, and elongated joint capsule with para-joint, peri-diaphysis, and inter-muscular extension in a pseudopodia pattern. The irregular joint capsule wall was presented as mild hypointensity on T 1WI, slight hyper-intensity on T 2WI, and was markedly enhanced after Gd-DTPA was administrated, which was considered as a characteristic manifestation of the lesion. Soft tissue mass containing hypo-intense stripes on both T 1WI and T 2WI was commonly noted adjacent to the involved joint. Conclusion X-rays plain film is the first choice for the diagnosis of Charcot joint, and MRI is pretty useful in the diagnosis of Charcot joint.

Objective To investigate clinical effects differences of ropivacaine combined with two doses of sufentanil on labor analgesia.Methods300 lying-in women with painless childbirth in the period from January 2016 to December 2016 in department of obstetrics in Deqing hospital of traditional Chinese medicine were chosen and randomly divided into two groups including A group (150 cases) with ropivacaine combined with conventional doses of sufentanil for 7.5μg and B group (150 cases) with ropivacaine combined with low doses of sufentanil for 2.5μg;the block onset time of sensory and motor, arrival time at the maximum block level, modified Bromage score, Apgar score, VAS score at different time points and adverse reaction rate of both groups were compared.ResultsTwo groups of maternal sensory and motor block work time and reach the highest block plane comparative differences had no statistical significance.The modified Bromage score of B group were significant better than A group(P<0.05).The adverse reaction rate of B group were significant lower than A group(P<0.05).ConclusionCompared with conventional dosage sufentanil, luo pp paid in combination with low dose used in epidural sufentanil analgesia can obviously reduce the working time, improve the quality of anesthesia and reduce the incidence of adverse reactions, is suitable for clinicians to choose application.

Objective: To survey the content of serum total cholesterol, LDL and HDL in pa- tients with gastric cancer and to investigate the correlation between serum total cholesterol, LDL, HDL and the differentiation of gastric cancer. Methods: 143 patients with gastric cancer were selected and assigned into 3 groups according to pathology grouping after operation: 1) the well-differentiated group, consisting of 16 patients with papillary adenocarcinoma, and 43 patients with tubi-form well-differentiated adenocarcinoma; 2) the moderately differentiated group, including 39 patients with tubiform moderately differentiated adenocarcinoma, 3) the poorly differentiated group, including 20 patients with poorly differentiated adenocarcinoma, and 14 patients with mucinous adenocarcinoma, and 11 patients with signetring cell carcinoma. In addition, 30 patients with gastric ulcer and 30 health adults were selected as control. Veinous blood of every member was collected, and then the content of serum total cholesterol was surveyed by enzymic method, and the contents of serum LDL and HDL were measured by precipitation method. Results: The level of serum total cholesterol, LDL and HDL before operation in patients with gastric cancer decreased significantly than those with gastric ulcer and normal people (P0.05). There was statistically significance among different differentiation in patients with gastric cancer. The differences of levels of serum total cholesterol, LDL and HDL were statistically significant in gastric cancer of different differentiated groups. The contents of serum cholesterol, LDL and HDL in 40 patients with gastric cancer after operation were higher than those before operation obviously (P

BACKGROUND:Antedor canulated screw has been considered an ideal method to treat odontoid fracture.OBJECTIVE:To compare the biomechanical properties of different anterior screws.DESIGN,TIME AND SETTING:A randomized contrast study was performed at the Biomechanics Laboratory of Southern Medical University from March to September 2006.MATERIALS:Double-thread canulated screws and single-thread canulated screws were made of titanium alloy and provided by Shuangyang Medical Apparatus Co.,Ltd.,Suzhou.METHODS:A total of head-neck complexes (C0-C3) which were collected from 20 corpses were maintained in formaldehyde for less than 3 months;thereafter,the muscles and ligaments were removed to obtain the axis specimens so as to make type Ⅱ odontoid fracture models.The fracture samples were individually treated with double-thread and single-thread canulated screws,with 10 samples for each group.MAIN OUTCOME MEASURES:The shear stiffness and the maximum resistance of the two kinds of screw were tested in this study.RESULTS:The shear stiffness of the double-thread screw group was significantly higher than the single-thread screw group (P＜0.01 );however,there was no significant different in the maximum resistance between the two groups (P＞0.05).CONCLUSION:Double-thread canulated screws have a strong biomechanical stability for treating odontoid fracture;therefore,the first choice of the internal fixation should be double-thread canuiated screws for patients with osteoporosis or those who are susceptible to expanded screw pathway during surgical procedures.

ObjectiveThe aim in this study was to evaluate the efficacy of the ball tip probe technique in placing pedicle screws in patients.MethodsFrom May 2009 to June 2010,we used ball tip probe technique in pedicle screw placement in patients with scoliosis,spondylolisthesis,spinal fractures and other diseases.The ball tip probe consisted of a metal shaft with a metal ball-shaped tip whose size included 1.5,2.5,3.0,3.5 mm in diameter.The ball tip probe with a diameter of 1.5mm owned a high rigidity and certain flexibility.Ball tip probe technique:A high speed bur was used to remove cortical bone and create a starting point,and then the ball tip probes is tapped gently by a hammer for making a guide hole through the pedicle into the vertebral body.The accuracy of the pedicle screw placements was evaluated on postoperative axial CT scanning The pedicle screw placements was compared between the the ball tip probe group and conventional freehand technique group.ResultsThree hundred and twelve screws were evaluated in the ball tip group and 276 in the conventional freehand group.All the screws (100％) were in the desired pedicle in the ball tip group and 215 (78％) in the conventional group.In the conventional group,23 screws(8.3％) were classified as medial violation; 38(13.7％) as lateral violation.A significant difference was determined between the 2 groups regarding the pedicle breaches.No vascular,pulmonary,or neurological injuries caused by pedicle screws placement was found in either group.ConclusionThis study demonstrates the accuracy and reliability of the ball tip probe technique in pedicle screw placement.This technique can probably reduce the risk of complications of screw misplacements.

Duck circovirus(DuCV),a potential immunosuppressive virus,was investigated in Southern China from March 2006 to December 2009 by using a polymerase chain reaction(PCR)based method. In this study,a total of 138 sick or dead duck samples from 18 different farms were examined with an average DuCV infection rate of～35%. It was found that ducks between the ages of 40～60 days were more susceptible to DuCV. There was no evidence showing that the DuCV virus was capable of vertical transmission. Farms with positive PCR results exhibited no regularly apparent clinical abnormalities such as feathering disorders,growth retardation or lower-than-average weight. The complete genomes of 9. strains from Fujian Province and 1 from Zhejiang Province were sequenced and analyzed. The 10 DuCV genomes,compared with others genomes downloaded from GenBank,ranged in size from 1988 to 1996 base pairs,with sequence identities ranging from 83.2% to 99.8%. Phylogenetic analysis based on genome sequences demonstrated that DuCVs can be divided into two distinct genetic genotypes,Group I(the Euro-USA lineage)and Group II(the Taiwan lineage),with approximately 10.0% genetic difference between the two types. Molecular epidemiological data suggest there is no obvious difference among DuCV strains isolated from different geographic locations or different species,including Duck,Muscovy duck,Mule duck,Cheery duck,Mulard duck and Pekin duck.
