Objective To explore whether health examination save medical insurance fund or not. Methods To observe the sparing medical cost which 371 health examination people avoid repeated checking and shorten the length of stay during hospitalization from March 2006 to March 2007. To observe the effect of sparing medical cost because of regular health examination, early discovery diseases, pretreatment promptly and avoidance transforming to advanced diseases. Results Because of avoiding repeated checking and shortening the length of stay,everybody save the medical cost about 570 yuan,371 people can save about 21 ten thousands yuan. To statistics the average hospital cost of different courses of eight common diseases and malignant tumors from January to November at 2007, we discovered that the medical cost is large distinction between the earlier period and advanced stage of disease. For example: the medical cost of one stage of hypertension is 6608 yuan ,the two stage is 8838 yuan ,the three stage is 13 869 yuan, and the stage of hypertensive heart disease is 13 033 yuan. Parts of health examination crowd who stay at my hospital from 1996 were visited for five years ,we conformed many chronic diseases by prompt intervention can relieve and even reverse, avoiding the transformation to incurable disease which will consume a large number of strength and money. Conclusion Health examination resource is a medical treatment resource which isn't restricted by social security fund, the utilization can not only save medical cost but also discover and treat diseases earlier, thus we can save the strength and money before the advanced diseases.

Objective To explore the effect of nBiPAP on ET-1 of patients with overlap syndrome.Methods Levels of ET-1 in plasma of 25 cases of OS,20 cases of COPD were analysed by radioimmunoassay,and ET-1 in OS was measured before and after treatment.The relationship between ET-1 with SaO_2 during sleep was analyzed. Results (1)The ET-1 levels in plasma of OS group were significantly higher than those of COPD group before treatment(P

A possible ?-Galactosidase gene(pwtsA) was discovered from soil metagenomic DNA of Taishan Mountain.PwtsA gene was inserted into the expression vector pET30a and transferred into E.coli BL21(DE3).Recombinant protein PWTSA was expressed as a soluble form at high level through IPTG induction,with a molecular mass of 57 kD analyzed by SDS-PAGE.PWTSA can produce o-nitrophenol from o-nitrophenol-?-D-galactopyranoside(ONPG),and its specific activity was determined as 13.6 U/mg.The enzymatic studies demonstrated that the recombinant protein PWTSA was a thermostable ?-Galactosidase,its optimum temperature and pH were 85?C～95?C and 6.5 respectively.In standard assays,the Km for ONPG was 0.83 mmol/L.

OBJECTIVETo evaluate the effects of carbon monoxide releasing molecule-2 (CORM-2) on experimental periodontitis in rats.

METHODSForty-two Wistar rats were divided into three groups. Rats in the normal group (NL group) did not undergo any procedure, whereas the other rats were ligatured and treated with saline solution (NaCl 0.9%) (LO group) or treated with CORM-2 (10 mg kg(-1) per day) (CO group). A 3-0 silk suture was placed around the mandibular first molars. Rats were sacrificed after 3, 7, and 10 d. Blood samples were collected from all animals for tumor necrosis factor-alpha (TNF-alpha) and interleukin-1beta (IL-1beta) analysis. Changes in alveolar bone levels were measured clinically, and periodontal tissues were histopathologically examined to assess the infiltration of inflammatory cells.

RESULTSLigature placement increased alveolar bone loss and inflammatory cell infiltration in periodontal tissue. Alveolar bone loss in CO group was significantly higher than that in NL group, but was lower than that in LO group (P<0.05). The ratio of inflammatory cell infiltration in LO group was significantly higher than that in CO and NL groups, and that in CO group was lower than in LO group (P<0.05). Serum levels of TNF-alpha and IL-1beta in the LO group were significantly higher than those in the CO and NL groups, and those in CO group were lower than in LO group (P<0.05).

CONCLUSIONSystemic administration of CORM-2 reduced periodontal inflammation and alveolar bone loss in experimental periodontitis in rats.

BACKGROUND:The incidence of complications folowing conventional repairing for the ruptured tendon is up to 73%, such as delayed healing, adhesion, secondary rupture. These complications severely affect ankle joint function of the patients. OBJECTIVE:To reduce the complications folowing the repair and investigate the role of hernia repair materials in the repairing of ruptured Achiles tendon. METHODS:Eleven patients who underwent repair of ruptured Achiles tendon were retrospectively studied. Among them there were eight males and three females with the mean age of 42 years (26-58 years). Three cases were injured in left side and eight cases were in right side; four cases were open injury by sickle-induced damage and seven cases were closed injury by exercise-induced damage. The hernia repair materials after pruning was applied with a “wrap” method to strengthen the anastomosis repair of Achiles tendon after the conventional repair surgery had been completed. At the time of folow-up, al patients were observed for postoperative local appearance and function recovery, and assessed with Arner Lindholm standards. RESULTS AND CONCLUSION:The folow-up interval was 6-45 months (average 24.5 months). Two cases were lost to folow-up. According to the Arner Lindholm standards, the effects were excelent in seven cases (78%) and good in two cases (22%). Local appearance and function recovered wel postoperatively, and no complications occurred such as wound infection, secondary rupture and so on. A “wrap” method with hernia repair materials is suggested to strengthen the anastomosis repair of ruptured Achiles tendon after the conventional repair surgery is completed, it can significantly promote the healing of Achiles tendon ruptured end anastomosis, prevent Achiles tendon recurrent ruptures, local adhesion and infection.

Attention deficit hyperactivity disorder(ADHD)is a common childhood behavioral disorder,and it is characte-rized by the core symptoms of attention deficit,hyperactivity and impulsivity.In recent years,a variety of neuropsychological deficits related to ADHD have been confirmed,including intelligence,attention and inhibition,verbal and spatial working memory,set shift,planning and monitoring.Some important theories related to the metal mechanism of ADHD have been put forward,and the representatives include behavioral inhibition theory,cognitive-energetic model,dual pathway theory and state regulation theory.
