The foreign bodies in the upper GI tract are produced chiefly by accidental swallowing and rarely produce symptoms. But it is recommended to remove the foreign bodies if they produce symptoms or retained in GI tract for long duration, and if they have the possibilities of producing complications. Nowadays the development of therapeutic endoscopy enables the removal of the foreign bodies easily. We have reviewed 88 cases of foreign bodies diagnosed by endoscopy from January, 1980 to July 1990 and had the following results. 1) The most common foreign bodies were coins and bezoars, common with the ages under 10 years and over 50 years. 2) The foreign bodies were found in the upper gastrointestinal tract in the order of stomach, esophagus and duodenum. 3) The esophageal stricture especially by lye was the most common underlying cause of upper gastrointestinal foreign bodies. 4) The symptoms and complications were more common with esophageal foreign bodies. 5) By therapeutic endoscopy, the success rate for removal of foreign bodies was 98%.

The formulation for sustained release tablet of Epinedium component was selected and the evaluation equation of in vitro release was established. The liquidity of component was improved with the help of colloidal silica aided by spray drying, which would be the main drug in the sustained release tablets. Dissolution was selected as an evaluation index to investigate skeletal material type, fillers, impact porogen, lubricants and other materials on the quality of sustained release tablet. The sustained release tablets were prepared by dry compression. Formulation of sustained release preparations was main drug 35%, HPMC K(4M) 20% and HPMC K(15M) 10% as skeleton material, MCC 31% as filler, PEG6000 2% as porogen and magnesium stearate 2% as lubricant. The sustained release tablets released up to 80% in 8 h. The zero order equation, primary equation and Higuchi equation could simulate the release characteristics of sustained release tablets in vitro, the correlation coefficients r were larger than 0.96. The primary equation was most similar in vitro release characteristics and its correlation coefficient r was 0.9950. The preparation method is simple and the results of formulation selection are reliable. It can be used to guide the production of Epimedium component sustained release preparations.

OBJECTIVETo evaluate percutaneous reduction by Kirschner pin and internal fixation with cancellous screw and plate through minimal incision at the lateral side of heel for the treatment of intra-articular displacement fracture of calcaneus.

METHODSFrom September 2009 to June 2012, 80 patients with close intra-articular displacement fractures of calcaneus were divided into treatment group and control group. There were 40 patients in the control group, including 21 males and 19 females, ranging in age from 23 to 64 years old, averaged (39.1 +/-11.7) years old; and the patients were treated with fixation by compress screws and plates of self-broken type. There were 40 patients in the treatment group, including 24 males and 16 females,ranging in age from 21 to 67 years old, averaged (39.6+/-14.3) years old;and the patients were treated with full thread cancellous screws and plates fixation. The fixation time,intra-operative blood loss and the number of injured medial plntar nerve were compared between the two groups. The Böhler angle, Gissane angle and the correction degree of calcaneal width were measured at 1 year after operation. The internal fixators were taken out after 1 year. The AOFAS ankle-hindfoot score was used to evaluate therapeutic effects.

RESULTSAll the patients were followed up,and the duration ranged from 9 to 32 months, with a mean of 16 months. There were shorter operation time, less injury, satisfactory postoperative Böhler angle and calcaneal width in treatment group compared with control group,which reduced the medial neurovascular injuries, and the plate was easily removed after fracture healing.

CONCLUSIONFull thread cancellous screws and plate fixation for the treatment of calcaneal fractures could get same therapeutic effects as compress screws and plate of self-broken type fixation, and also has follow advantages: shortening the operation time, reducing blood loss, easily to be removed, avoiding the medial neurovascular damage, reducing the incidence of complications.

Objective To investigate the characters of the COL3A1 gene polymorphisms in Chinese population of Hunan region and the relationship between the COL3A1 gene polymorphisms and ischemie stroke.Methods Objects examined were composed of 70 healthy controls,110 patients with acute cerebral infarction.The frequencies of the genotypes were detected by using PCR-SSLP techniques and correlated PCR segements were analyzed by directly sequence to detect the COL3A1 gene polymorphisms.Result There were significant differences in the distribution of VNTR with COL3A1 genotype polymorphism between the patients of acute cerebral infarction and healthy controls,the former being 0.93,the latter 0.43,with a significant difference(P

Two pairs of primer targeting to the genes encoding the major outer membrane protein (MOMP) and the polymorphic membrane protein (PMP) of Chlamydophila psittaci (Cps) designed and used in the fluorescent quantitative PCR assay in the detection of this microorganism were compared in the their sensitivity and specificity.It was demonstrated that both pairs of primer could be used successfully to detect the presence of Cps of the epidemic strains isolated in China.The specificity of PMP primer used was higher than that of MOMP primer. In case of high target concentration in samples, the sensitivity of the former was also superior to that of the latter, but the amplification efficiency of the former was lower than that of the latter. The MOMP primer seemed to be more suitable to detect Cps by using the real-time quantitative assay.As demonstrated by the real-time quantitative PCR assay, great difference in the genomic copy numbers of the PMP gene existed in the epidemic strains of Cps isolated in China.

Objective To learn the prevalence and trends of Brucella disease in Ningxia, in order to provide scientific basis for effective control of the disease. Methods Data of Brucella cases reported through city network from 2004 to 2009 in Yinchuan city, Shizuishan city, Wuzhong city, Guyuan city and Zhongwei city of Ningxia were reviewed and retrospectively analyzed. The data included demographic characteristics, treatment conditions and medical history so on related information. Analytical indicators include reported incidence;with patients' gender, age, regional distribution, urban and rural distribution;become chronic and associated factors;distribution of the cases reporting unit and so on. Results From 2004 to 2009, Ningxia had reported 349 cases of Brucellosis, no deaths, the annual incidence rates reported were 0.017/10 million, 0.543/10 million, 0.151/101 (295/54);The proportion of 34- to 40-year-old age group was higher than other age groups(27.5%, 96/349);Occupational distribution of patients was mainly farmers and herdsmen(70.2% ,245/349), in regional distribution of the patients, the highest percentage was Wuzhong city(61.9%,216/349), followed by Yinchuan city(22.9%,80/349);The proportion of patients in rural areas(97.4% ,340/349) was higher than urban(2.6% ,9/349);the proportion of patients converted to chronic was 11.2% (39/349). With age, the chance of patients converted to chronic was in a decreasing trend(odds ratio was 0.966);cases reported by Centre for Disease Control and Prevention accounted for 74.8%(261/349), by hospital accounted for 25.2%(88/349). Conclusions The reported incidence of Brucellosis in Ningxia is in a rapid upward trend year by year, the patients is mainly young men, the rate of converted to chronic is higher and the ability of hospital in founding and reporting of the cases is weaker.Comprehensive measures should be taken to increase funding, strengthen monitoring, and continuously improve the level of awareness and diagnosis of medical personnel for further strengthen the prevention and control of Brucellosis.

Objective To study the changes of phosphatidylcholine-specific phospholipase D (PC-PLD) enzyme activity of glomerular mesangial cells (GMCs) in high glucose and the effect of PLD on cytoskeleton. Methods Rats GMCs were cultured in high glucose(30 mmol/L) for 48 hours. PLD enzyme activity was measured by enzyme coupled colorimetry. PKC activity was measured by substrate phosphorylation, and fluorescence intensity of F-actin was observed by FITC-labeled antibody and laser scan cofocal microscopy (LSCM) . Results In high glucose, PLD and PKC activities were obviously elevated, but fluorescence intensity of F-actin was decreased and its cytoskeletal pattern was disassembly. After treatment with inhibtor of PLD, PKC activity was significantly decreased, and intensity and organization of F-actin were recovered. Conclusion Elevation of PLD activity induced by high glucose may influence the cytoskeleton and contraction of CMC through PKC pathway.

OBJECTIVETo compare clinical efficacy for the treatment of proximal humeurs fractures in elderly patients between the minimally invasive plate osteosynthesis (MIPO) with less invasive stabilization system (LISS) and the open reduction and internal fixation (ORIF) with locking compression plate (LCP).

METHODSFrom June 2008 to June 2011, 40 elderly patients suffering from proximal humeurs fractures were divided into two groups: 20 cases in minimally invasive group and 20 cases in routine group. Mini-incision approach from the lateral shoulder (minimally invasive group) and LISS can be chosen. It was short for MIPO. The antero-medial incision was used in routine group, LCP can be chosen in the method of ORIF. The operation time, the blood loss, the incision length, soreness at 1st, 3rd and 7th days after operation were recorded. The postoperative Neer score, the healing time of bone were recorded. The curative effects were compared according to Neer score system.

RESULTSThe mean operation times were (133.60 +/- 8.90) min and (132.70 +/- 8.41) min in minimally invasive group and routine group (P > 0.05). The blood losses were (155.20 +/- 19.07) ml and (324.05 +/- 48.32) ml (P < 0.05). The incision lengths were (8.15 +/- 1.89) cm and (13.05 +/- 1.95) cm (P < 0.05). The pain scores on the 1st,3rd and 7th days after operation were (6.20 +/- 2.39) and (8.33 +/- 3.01) (P < 0.05), (3.83 +/- 2.09) and (5.31 +/- 2.22) (P < 0.05), (1.22 +/- 0.89) and (3.13 +/- 1.75) (P < 0.05). The postoperative Neer scores were 93.16 +/- 2.55 and 80.31+/- 2.22 (P < 0.05) and the healing times of bone were (6.60 +/- 2.33) months and (8.93 +/- 3.41) months (P < 0.05). There were statistially differences in the blood losses, incision lengths, postoperative pain scores, postoperative Neer scores and the healing times of bone between two groups (P < 0.05). The operation time between the two groups had no statistically different (P > 0.05). According to Neer score system, 13 patients obtained an excellent results, 2 good, 5 fair in minimally invasive group; 6 patients obtained an excellent results, 5 good, 9 fair in routine group.

CONCLUSIONTo compare with the routine group of ORIF, MIPO with LISS has the advantages of small incision, easier operation, less blood loss and improved postoperative shoulder joint function recovery for treatment of proximal humeurs fracture in elderly patients. It is another better method of internal fixation.
