The health workforce plays an important role in the development of township hospitals. It builds up the comprehensive evaluation index system as the first time, based on data of township hospitals from 29 provinces, to evaluate the allocation of the health workforce in primary medical institutions in rural China. The empirical results show that the core workforce allocation of Chinese township hospitals has largely focused on the local health status, which shows good fairness of allocation. Meanwhile, the equity level of the core workforce allocation is not far behind the overall fairness level, and both are slightly higher than the critical value. The core workforce allocation is in good consistency with the local level of economic development.

Dental stem cells(DSCs)possess the characteristics of stem cells and can be effectively obtained from iatro-waste products (such as impacted wisdom tooth and the extracted teeth for orthodontic reason).It has been proved that DSCs are the important sources of stem cells for tissue engineering and regenerative medicine research.Research of these stem cells will create broader space for tissue engi-neering and regenerative medicine and will have important values in translational research.This review gives an overview of the research pro-gress of dental stem cells,and presents some new findings of several common dental stem cells as well as the application in tissue regenera-tion.

Objective To study the clinical study of the effect of removing blood stasis and eliminating powder on the recovery of wrist function after distal radius fracture.MethodsA total of 82 patients with distal radius fractures were selected from September 2012 to October 2016.The random number table method was divided into study group and control group.The two groups were given intervention, and the study group (VAS score), the correlation index(swelling time, pain time, fracture healing time), clinical curative effect and the recovery of wrist function were observed and compared with the two groups.ResultsAfter treatment, the VAS scores of the two groups were significantly lower than those before treatment, and the VAS scores of the study group were significantly lower than those of the control group (P<0.05).After the treatment group, the swelling time, pain time (P<0.05).After treatment, the total effective rate was 87.80% higher than that of the control group (68.29%) (P<0.05).After treatment, the two groups were significantly higher than those in the control group (P<0.05), and the wrist function scores of the study group were significantly lower than those of the control group (P<0.05).ConclusionThe combined effect of removing blood stasis and eliminating powder is effective in the treatment of distal radius fractures, which can effectively reduce the pain and reduce the healing time of the fracture and promote the recovery of the wrist function.

It is getting very competitive in the application to Natural Science Foundation of China.To improve the chances of success in the application, we summarized and analyzed the peer review opinions for the 91 failed applications from 2004 to 2008. Problems were disclosed for these application projects in scientific significance, research content, research design, novelty, preparative research, research group,and application writing. Countermeasures were proposed for the department of research to improve the application quality.

Objective:To establish an atomic absorption spectrometry method for the determination of lead and ferrum in pre-mix-ture coating film. Methods:The samples were digested by microwave digestion system, and Pb was determined by graphite atomic ab-sorption spectrometry(GFAAS), and Fe was determined by flame atomic absorption spectrometry(FAAS). Results: There was good linear relationship within the range of 1.0-5.0 μg·L-1(r=0.999 4) for lead and 0.1-1.0 mg·L-1(r=0.998 4) for ferrum. The recovery of lead was 91. 3%(RSD=1. 4%,n=9)and that of ferrum was 89. 9%(RSD=3. 5%,n=9). Conclusion: The method is accurate and stable, which can be used for the determination of lead and ferrum in pre-mixture coating film

Objective To study the correlation between chronic gastritis with benign mucosal nodular-change,Helicobacter pylori(H.pylori)infection and lymphoid follicles infiltration.Methods During July 1,2004 to June 30,2005 patients with chronic gastritis and benign mucosal nodular-change were identified by chromo-endoscopy with anabrosis indigo carmine staining at the antrum.Multiple biopsies were obtained for H.pylori detection with quick test and for pathology examination of mucosal lymphoid follicles formation and lymphocyte infiltration,as well as H.pylori infection.Results The patients were divided into nodular gastritis group,atrophy gastritis group and verrucous gastritis group with mean age of(31.00?11.62),(58.61?12.14)and(51.29?12.99)years old,respectively.The patients with nodular gastritis were the youngest(P

Objective To investigate the oncologic and reproductive outcomes after progestin treatment of complex endometrial hyperplasia(CEH) and grade 1 endometrial carcinoma(EC).Methods In a retrospective study, data were obtained for patients with CEH or grade 1 EC at presumed stage IA(without myometrial invasion) who wished to preserve fertility and were treated at the Peking Union Medical College Hospital, China, between January 1, 2000 and December 31, 2011.Patients had received oral medroxyprogesterone acetate(250-500 mg/d) or megestrol acetate(160-480 mg/d) for at least 6 months.Results Among 55 included patients, median age was 32 years(range 21-41 years).41(75%) achieved complete response after a median period of 6(3-24) months.Complete response was less frequent among obese than nonobese patients(4/12 [33%] vs 37/43 [86%];P=0.001).Disease recurrence was recorded in 10(24%) patients with complete response;the 5-year recurrence-freesurvival rate was 71%.Among the 33 patients who retained a desire to conceive, 17(52%) became pregnant.Conclusions Fertility-sparing management with oral progestin is effective and safe.Obesity is associated with a lower probability of long-term success.

Objective To study the preparation technique for Jiegeng Zaogan capsules (capsules of total saponins from the roots of Platycodon grandiflorum A.DC).Methods The optimal preparation technique for Jiegeng Zaogan capsules was investigated by L9(34) orthogonal test with the Platycodin D content as the observation index.Results The optimized extraction procedure was as follows:extracting for 3 hours each time and 3 times in total,adding 10-fold water,alcohol sedimentation concentration at 65 %,and alcohol sedimentation solution staying for 48 hours.Conclusion The preparation process of Jigeng Zaogan capsules is reliable with stable quality,which offers a feasible method for the industrialization production of the capsules.
