Objective To observe the differences in functional capacities generated by different simple breathing balloons extruded by different hand types and methods.Methods The lung functional measurement instrument was used to measure the generated functional capacities of two types of simple breathing balloon extruded by different hand methods: using big-, mid- and small-size hands with 5 fingers generally separately open and maximally extended states or with both small-size hands to extrude balloon; the effective generated gas quantity of the above methods were compared.Results ① Comparison between different balloons: the functional capacity generated by black rubber balloon extruded by any hand type was 68 - 132 mL lower than that generated by light blue silicon balloon. ② The comparison between different hand types: the functional capacities generated by any hand at maximally extended state in extruding balloon was 13 - 70 mL higher than that by hand commonly separate state; extrusion by a small size hand was nearly unable to reach 400 mL, while the functional capacity was 520 - 650 mL when the balloon was extruded by a big size hand, and 435 - 635 mL by a mid-size hand; it was necessary to use both small hands when the black rubber balloon was extruded, when the light blue silicon air bag was extruded, the functional capacity could reach 430 - 440 mL with a small size hand. ③ Difference in extruding methods: the functional capacity generated by either big size hand or mid-size hand with 5 fingers maximally extending state to extrude balloon was significantly higher than that with 5 fingers commonly separate state, the functional capacity generated by both small size hands with fingers maximally separating and extending state to extrude balloon was obviously higher than that generated by 5 fingers generally separating and extending state, the functional capacities generated by light blue silicon balloon were obviously higher than those by black rubber balloon, no matter the 5 fingers of big- or mid-size hand being at generally separating or extending state (mL: 623.00±21.11 vs. 522.00±41.85 by big size hand with common 5 fingers separate state, 649.00±26.01 vs. 575.00±58.55 by big sizehand with maximum 5 fingers extending state; 566.00±37.77 vs. 436.00±21.19 by mid-size hand with common 5 fingers separate state, 637.00±30.02 vs. 505.00±37.49 by mid-size hand with maximum 5 fingers extending state); the light blue silicon balloon extruded by small hand with 5 fingers at generally separate state and at maximally extending state could generate functional capacities (mL)432.00±13.02 and 444.00±37.18 respectively, significantly higher than those using the 2 types of hand state extruding a black rubber balloon (the tidal volume < 400 mL), the functional capacities generated by both small hands extruding a light blue silicon balloon was obviously higher than that by using a black rubber balloon (mL: 557.00±54.98 vs. 489.00±40.12, allP < 0.05).Conclusions Different functional capacities will be generated by different hand sizes, different hand extruding methods and types of simple breathing balloon, clinical application should be based on patients' body weights to decide their tidal volumes, and combined with the rescuers' hand sizes and types of simple breathing balloon to choose a proper extruding method for a certain patient, thus sufficient oxygen can be surely provided in time for him/her and rescue successful rate can be elevated.

Objective:To investigate the pediatricians' needs in the contents of continuing medical education (CME), and the influencing factors of participating in CME, so as to provide references for improving their vocational ability.Methods:Questionnaire survey was carried out for the pediatricians from county-level medical institutions in the nine provinces of China. The questionnaire contents included: basic information, CME contents needs, and influencing factors of participating in CME. SPSS 22.0 was used for chi-square test.Results:A total of 465 questionnaires was recovered, among which 463 were qualified, with a pass rate of 99.6%. Research showed that ① In terms of competency training needs, pediatricians had higher training demand for ability of diagnosis and treatment of children's diseases, pediatrics basic skills and skills related to children's health care, etc. Pediatricians with junior or intermediate title had higher training demand for ability of self-learning and access to learning resources ( P < 0.01); and pediatricians with senior title had higher training demand for teaching ability ( P < 0.05). ② In terms of pediatrics specialty content training needs, pediatricians had higher demand for neonatology, infectious, respiratory, critical medicine, developmental behavior and digestion in order. ③ Regarding the influencing factors of CME, too few opportunities to participate in training, too busy to have time to participate, and defects in curriculum arrangement were the main factors affecting the CME participation of pediatricians. Conclusion:Pediatricians with different professional title had different training needs for CME contents. Lack of CME resources, contradiction between work and study, and curriculum arrangement deficiencies might be the main influencing factors affecting the CME participation of pediatricians working at county-level medical institutions.

OBJECTIVETo observe clinical efficacy in treating cutaneous deficiency of traumatic shank amputation stump with full-thickness skin graft combined with vacuum sealing drainage.

METHODSFrom September 2009 to December 2012, 15 patients with cutaneous deficiency of traumatic shank amputation stump were treated with full-thickness skin graft combined with vacuum sealing drainage. Among patients, there were 11 males and 4 females with an average age of 41.5 (ranged from 25 to 62) years old. Ten cases were caused by traffic accident and 5 cases were caused by heavy object, 9 cases on left and 6 cases on right. Six patients with smashed wound were treated with debridement and amputation, combined with vacuum aspiration in-emergency; 9 patients caused by infection and necrosis were treated with debridement and amputation, combined with vacuum aspiration, and full-thickness skin graft were performed at stage II. The skin defect area of residual limbs ranged from 40 cm x 20 cm to 25 cm x 15 cm.

RESULTSAll patients were followed up from 3 months to 1 year. Full-thickness skin graft of residual limbs were survived,and obtained satisfactory walking function with prosthetic. Residual skin increased thicken, wearproof without rupture and pain.

CONCLUSIONFull-thickness skin graft combined with vacuum sealing drainage in treating cutaneous deficiency of traumatic shank amputation stump could reserve the length of residual limbs, increase survival rate of skin graft with less scar of survival skin, get good wearability and it is conducive to prosthetic wear. It is a simple and easy treatment method.

[Objective]To investigate the effect of pantoprazole on skeletal muscle wasting in cancer cachexia and the possible mechanism.[Methods]24 male BALB/c mice were randomly divided into control group(NN),cancer cachexia group(CC),pantrop?razole treatment group(PPI). The mice in CC and PPI were inoculated subcutaneously with mouse colon adenocarcinoma C26 cells to establish a model of cancer cachexia. The mice in PPI group were gavaged with 75 mg/kg pantoprazole dissolving in physiological saline,while those in NN and CC group were gavaged with 0.1 mL/10 g physiological saline. The mice were killed 12d after treatment. The weight of gastrocnemius and tumour and the size of tumour were measured. The morphological change of skeletal muscle were evalu?ated by the method of stain with hematoxylin and eosin(H&E). The levels of IL-6 and TNF-αin serum were tested by ELISA. qRT-PCR was used to assess the expression of mRNA of Myod1 and myf5 in skeletal muscle. The protein expressions of MuRF1,MAFBx, Myod1 and myf5 were measured by Western blot.[Results]Compared with CC group ,pantoprazole can increase the weight of mice and gastrocnemius(39.8% and 24.2%,respectively),cross section area(25.4%),levels of mRNA and protein of Myod1 and myf5(P<0.05),while the levels of IL-6 and TNF-αdecreased(30.7%and 18.9%,respectively),as well as the levels of protein ex?pression of MuRF1 and MAFBx(P < 0.05).[Conclusion]Pantoprazole can attenuate the wasting of skeletal muscle,the potential mechanism may be related to the inhibition of inflammatory factors and UPS ,and up-regulation of Myod1 and myf5.

Objective To summarize the epidemiological feature of plague cases oceuwed in China.Methods The epidemiological and clinical data from 1981 to 2006 year in China were analyzed with descriptive study method.Result Nine hundred and seveneteen human plague cases were diagnosed in 9 provinces(regions) from 1981 to 2006 years,105 cases died,the mortality rate being 11.45%,and they distributed in 69 counties (cities or banners).In Qinghai Province 108 cases were diagnosed,the mortality rate was 46.30%(50/108),the cases distributed in 17 counties(cities);137 cans in Guizhou,distributing in 2 counties(cities);517 cases in Yunnan,distributing in 26 counties(cities).Plague cases peaked separately in 1983,1990,1996 and 2000 years,they were 25,75,98 and 254 separately.The principal spreading ways were breathing flying particles,touching,skinning and eating marmot in Qinghai;750 cases were of bubonic plague,among whom 4 cases in Tibet died,the fatality rate was 0.53(4/750);121 cases were of pneumonic prague,among whom 65 cases died,was accounting for 53.72%(65/121);31 cases were of septieaemic plague,and 30 cases died(one cases was cured in Inner Mongolia),accounting for 96.77%(30/31).Others were brain plague,intestinal plague,tonsil plague and plague cellulites,which were cured.Conclusion From 1990,human plague epidemical scope and intensity is enlarging continuously compared with 1980-1990 and there is a trend of going up gradually in China.

Objective To study the effect of positive lymph node number on the survival of patients with esophageal carcinoma. Methods From July 1995 to July 2005, a total of 11,447 resected lymph nodes were obtained from 1140 patients who underwent curative resection of the primary tumor with systematic lymphadenectomy at Shanxi cancer hospital. The survivals were analysed by life tables and Kaplan-Meier methods, the related factors of lymph node metastasis were assessed by Chi-square test. Results The number of positive lymph nodes was negatively related to survival rates of esophageal carcinoma. According to the number of lymph nodes resected (≥8 nodes versus <8 nodes), there was significant difference in metastatic lymph node ratio. Conclusion The number of positive lymph node can reflect the prognosis of patients better. The authors suggest that the modification of the tumor-lymphnode-metastasis (TNM) staging classification (TNM) to include the number of positive lymph nodes in the N1 category.
