Objective To understand the current situation of medical service and management in Luxi township health center (LxC) in Yongxin county of Jiangxi province, so as to provide baseline data about drug allocation, logistic key techniques research and products development for township health centers. Methods By means of questionnaire and focus interview, the LxC was investigated from the following aspects: general information, human resources, medicine list, basic device configuration, medical service and management, as well as service efficiency. Results a) Yongxin county including 13 village committees covers an area of 86 km2, with the population of 22 300 in 2009, and it pertains to a backward area with the annual per capita income of RMB 4 100 yuan; b) Among the total 28 staffs in LxC, 78.6% were health workers; the general practitioner (GP)/nurse ratio was about 1?0.58; the proportion of GP, nurses, medical technicians, other staffs was 54.55%, 31.82%, 9.09% and 4.54%, respectively; the proportion of bachelor degree, junior college graduation and secondary technical school graduation was 9.1%, 13.6%, and 77.3%, respectively; and the ratio of elementary, middle, and high professional title of health workers was 15?5?1; c) There were 625 species of drugs in LxC in 2009, and the hospital beds approved by government were 0.69 per thousand agricultural persons, which, however, were 1.15 in fact. The rate of 51 basic equipments shown in national regulation was actually 76.5%, and the readiness and utilization rate of existing 40 equipments was 92.5%; and d) In 2009, the outpatients were 12 150 person-time, with the average cost of RMB 29.39 yuan; the hospital discharge was 1 589 person-time, with the average stay of 12 days and the average cost of RMB 490.05 yuan; the vaccine inoculations were 5 053 person-time; among the total income, the medical service income accounted for 73.2%, while the drug income accounted for 53.7%; the personnel expenditure was 31.0% of the total, and the balance of income and expenditure was RMB –263 500 yuan. Conclusion The hardware condition of LxC is not so good owing to the financial difficulties of Yongxin county and Jiangxi provincial government. In comparison with the whole country, although the professional title structure is ok, health workers are still not enough, with unreasonable specialty structure and low educational background. The rate of basic equipments and the approved hospital beds per thousand agricultural persons are low. There are 625 species of drugs, containing 218 species shown in 2009 national essential medicine list. And the other conditions are as follows: no information system, lack of public health service, short of financial input, high ratio of “running hospital by selling drugs”, and low efficiency of medical service. So the top priority of LxC construction should be figuring out all of the above issues, and better serving the people.
Objective To compare the clinical efficacy and safety of thrombolysis with anticoagulation therapy for patients with acute sub-massive pulmonary thromboembolism. Methods The clinical data of 84 patients with acute sub-massive pulmonary thromboembolism were analyzed retrospectively, mainly focusing on the in-hospital efficacy and safety of thrombolysis and/ or anticoagulation. The efficacy was evaluated based on 6 grades: cured, markedly improved, improved, not changed, deteriorated and died. Results Among the 84 patients,49 patients received thrombolysis and sequential anticoagulation therapy( thrombolysis group) , 35 patients received anticoagulation therapy alone( anticoagulation group) . As compared with the anticoagulation group, the thrombolysis group had higher effective rate( defined as patients who were cured, markedly improved or improved, 81. 6% versus 54. 3%, P = 0. 007) , lower critical event occurrence ( defined as clinical condition deteriorated or died, 2. 0% versus 14. 3% , P = 0. 032) . There was no significant difference in bleeding rates between the two groups ( thrombolysis group 20. 4% versus anticoagulation group 14. 3% , P gt; 0. 05) . No major bleeding or intracranial hemorrhage occurred in any of the patients. Conclusions Thrombolysis therapy may be more effective than anticoagulation therapy alone in patients with acute sub-massive pulmonary thromboembolism, and thus warrants further prospective randomized control study in large population.
Objective To compare two kinds of myofascial flap encapsulating adi pose-derived stromal cells (ADSCs) in adi pogenic efficacy in vivo, and to provide experimental basis for the efficient transplantation of free adi pose tissue. Methods ADSCs were isolated from the subcutaneous adipose tissue in the neck of 10 New Zealand rabbits (aged 3-4 months old, male and female, weighing 2.0-2.5 kg), and primary culture and subculture of ADSCs were conducted. When the cells at passage 3 covered 70%-80% of the bottom of the culture flask, BrdU (10 μg/mL) was appl ied to label the cells for 48 hours before performing immunofluorescence staining. Oil red O staining observation was conducted to thosecells 2 weeks after being induced towards adi pocyte, al izarin red staining observation was performed 3 weeks after being induced towards osteoblast, and alcian blue staining was conducted 2 weeks after being induced towards chondrocyte. Besides, after being induced towards adipocyte for 2 weeks, 1 × 107 ADSCs/piece at passage 3 labeled by BrdU was seeded into Col I (10 mm × 10 mm × 5 mm/piece) to prepare cell carrier complex. The experiment was divided into two groups: group A in which vascular pedicled dextral latissimus dorsi fascial flap was adopted to encapsulate the complex; group B in which dextral gluteus maximus fascial flap with no specific vessel pedicle was appl ied to encapsulate the complex. Rabbits in each group went through autogenous ADSCs transplant and self control. The implants were dislodged 8 weeks after operation, HE staining and immunohistochemistry staining were performed to testify cambium, the wet weight and micro vessel count of the cambium in each group were tested, immunofluorescence staining was performed to determine the origin of cambium and microvascular endothel ium. Results The nucleus of ADSCs positive for BrdU label ing showed green fluorescence under fluorescence microscope, with the positive label ing ratio of ADSCs above 90%. For ADSCs at passage 3, the formation of red l ipid droplets within cells was observed 2 weeks after being induced towards adipocyte, red calcium nodules were evident 3 weeks after being induced towards osteoblast, and highly congregated cell mass positive for alcian blue staining appeared 2 weeks after being induced towards chondrocyte. Eight weeks after operation, neogenetic blood vessel grew into scaffolds and no obvious fibreencapsulation was observed in group A, while few blood vessel grew into scaffolds in group B. The wet weight of cambium in group A and B was (0.149 5 ± 0.017 3) g and (0.095 3 ± 0.012 7) g, respectively, indicating there was a significant difference between two groups (P lt; 0.01). HE staining showed the formation of neogenetic adipose tissue and the growth of micrangium in the implant, and the degradation and absorption of scaffold. The micro vessel count of group A and B was 31.2 ± 4.5 and 19.3 ± 2.6, respectively, indicating there was a significant difference between two groups (P lt; 0.01). Eight weeks after operation, the immunofluorescence staining of cambium showed that the cell nucleus of regenerated adi pocytes and partial capillary endothel ium in groups A and B presented green fluorescence. Conclusion ADSCs encapsulated by vascular pedicled latissimus dorsi fascial flap and collagen protein scaffold complex has a higher adi pogenic efficacy in vivo than the gluteus maximus fascial flap with no specific vessel pedicle.
Objective To analyze the dynamic efficiency of township hospitals. Methods Based on the DEA-Malmquist index, this research analyzed the change of the total factor productivity indices and the decomposition items of 281 township hospitals in Hunan province with panel data from 2000 to 2008. Results Among 281 township hospitals, less than half increased their scale efficiency, while more than half increased their total factor productivity, technology, whole efficiency and technical efficiency. Increasing technology and whole efficiency was the best way to improve total factor productivity. Besides, increasing technical efficiency and scale efficiency was the best way to improve whole efficiency. Conclusions The improvement of scale efficiency is key to developing the central township hospitals, while the improvement of technology is the key to developing general township hospitals.
