Objective: To investigate the current situation of drug supply and determinants of drug shortage in primary health institutions in Anhui province. Methods:Primary health institutions in Anhui province were selected as the main research subjects. One hundred and six (106) primary health institutions from three areas/districts in Anhui province namely northern Anhui,Central Anhui,and Southern Anhui were selected with stratified random sampling as the first sample,and 54 pharmaceutical producing enterprises and 62 pharmaceutical trading enterprises were selected with convenience sampling method as the second sample. The survey was conducted by issuing questionnaires to record views of the respondents to help understand the current situation of drug supply from the first sample and the main de-terminants and solutions of drug shortage from two samples. Results:13% of the primary health institutions still suffer from serious shortage of drug supply; the drug distribution rate varies greatly between units, and 19% of the primary health institutions have a drug distribution rate below 70%,and all primary health institution within the scope of inves-tigation experienced drug shortages. The frequency of choices of determinants of drug shortage were in sequence of or-der:drug demand instability (19.20%), drugs have a new and higher profit alternative (15.94%), etc.; The fre-quency of choices of solutions of drug shortage of primary health institution were in sequence of order:to improve the national list of essential medicines(12.78%),appropriate improvement in efficacy the low-priced varieties(with cura-tive effect) (12.03%),etc. Conclusions:Primary health institutions suffer from drug shortage issue widely,and the reasons for the shortage of drugs are more complicated;the government should continue to implement relevant policies, comprehensively improving the primary health institution drug supply mechanisms in all to prevent drug shortages.

Our study aims to investigate the roles that microRNA-214 (miR-214) plays in the epithelial mesenchymal transition (EMT) process and the development of interstitial cystitis (IC) in postmenopausal women by targeting Mitofusin 2 (Mfn2). IC bladder tissues and adjacent normal bladder tissues were collected from postmenopausal women. Immunohistochemistry (IHC) staining was conducted. The target relationship between miR-214 and Mfn2 was determined by a dual luciferase reporter gene assay. Adipose-derived mesenchymal stem cells (ADMSCs) were extracted from postmenopausal rats and assigned to the blank, mimics, miR-214 inhibitors, mimics negative control (NC), inhibitors NC, Mfn2 siRNA, miR-214 inhibitors and Mfn2 siRNA groups. Exosomes secreted by transfected ADMSCs were instilled into the bladders of postmenopausal rats. The expression of miR-214 and Mfn2 mRNA and EMT markers was assessed by qRT-PCR and western blotting. It was confirmed that Mfn2 was the target gene of miR-214 in IC. Compared with the normal bladder tissues, miR-214 decreased, but Mfn2 increased in IC bladder tissues. Compared with the blank group, the expression of miR-214 and the expression levels of N-cadherin, Fibronectin, Twist1, Snail and Vimentin mRNA and protein increased, whereas the expression levels of Mfn2, E-cadherin and ZO-1 mRNA and protein decreased in the miR-214 mimics and Mfn2 groups. The expression of MiR-214 and the expression levels of N-cadherin, Fibronectin, Twist1, Snail and Vimentin mRNA and protein decreased, whereas the expression levels of Mfn2, E-cadherin and ZO-1 mRNA and protein increased in the miR-214 inhibitors group. Our findings indicate that the inhibition of miR-214 promotes the EMT process and contributes to bladder wall fibrosis by up-regulating Mfn2, thus leading to the occurrence of IC in postmenopausal women.

Based on SWOT analysis and relevant information about the premarital healthcare services through on-site survey and literature research , this paper systematically analyzed the Strengths , Weaknesses , Opportunities and Threats of “one-stop” premarital healthcare services .It also puts forward some strategic suggestions on premarital healthcare services in China including enhancing communication and cooperation between the related national minis -tries and commissions , building a government-led multi-sectoral coordination mechanism , increasing the resource in-vestment , promoting the premarital health care service and pre-pregnancy physical examination integration , and strengthening publicity and mobilization of “one stop” service for premarital healthcare service policy recommenda-tions to provide a basis for decision-making in the promotion of the policy-related works .

Objective:To discuss the effects of premarital health care services on birth defects in order to pro-vide some references for promoting the premarital policy .Methods: The rate of premarital healthcare and the inci-dence of birth defects and other relevant data during the period from 2000 to 2014 were collected in Guangxi province using SPSS18 .0 statistical software to carry out descriptive analysis , rank correlation analysis and time series analysis of the relevant collected data .Results: With the increase in premarital healthcare rate , the incidence of birth de-fects, neural tube defects , cleft lip and fetal edema syndrome decreased .Having a premarital subsequent effect , the higher the premarital healthcare rate , the lower of the incidence of the congenital heart disease and neural tube de-fects in the next year .Conclusion:The premarital healthcare services play an important role in reduction of birth de-fects and people's health quality improvement .As a suggestion , more attention should be paid to premarital health-care services and strengthen them , intended to improve people's health and reduce birth defects incidence .

With the universal two-child policy implementation, the birth rate increased, posing challenges to pediatrician allocation. Based on the birth rate, we calculated pediatrician demands and gaps during the period from 2016 to 2020 by the method of health service demand. The results showed that except Beijing and Shanghai, the ped-iatrician supply and demand ratios are less than 0 . 80 and additional numbers of pediatricians ranging from 191 981 to 198 287 are needed to meet the service demands. We recommend increasing the number of pediatricians taking both national supply-demand ratios and gaps by rationally using reasonable enrolment quota and improving the treatment and other reasonable ways to increase pediatricians. In addition, we should enhance information disclosure and guid-ance, and improve the hierarchical hospital visit system to alleviate the pressure of big cities.

With the universal two-child policy implementation, the birth rate increased, posing challenges to the maternity beds resource allocation. Based on the birth rate and the method of health service demand, we calculat-ed the maternity beds demands and gaps during the period from 2016 to 2020 . Results showed that numbers between 73 478 and 99 004 of maternity beds are needed annually and mainly allocated to eastern and central areas as well. In addition, the maternity beds of different delivery institutions should be adjusted and the hierarchical diagnosis system should be improved in order to alleviate the pressure of the obstestric acceepts in big cities like Beijing and Shanghai.

Objective To analyze biomechanical properties of cervical spine after anterior cervical discectomy and fusion (ACDF) and total disc replacement (TDR) surgery. Methods Twelve cadaveric cervical spines (C2-T1) were adopted, and the motion and load distributions of the cervical segments under intact state and after ACDF and TDR surgery were tested using a three-dimensional (3D) optoelectronics measurement system. All the tests were carried out with displacement control in directions of flexion (Flex), extension (Ext), left bending (LB), right bending (RB), left rotation (LR) and right rotation (RR). Motion characteristics of the normal cervical spine and the implant were also discussed. Results In TDR-treated specimens, range of motion (ROM) was well preserved and could restore to the normal ROM distributions, especially in Flex/Ext and LR/RR direction. While in ACDF-treated specimens, ROM presented a large decrease as much as to 73.41% under the same condition compared with TDR, and ROM distributions were also changed obviously in other motions for the segments. Significant changes of ROM in LB/RB direction occurred in both TDR and ACDF group, which were up to 45.92% and 108.06%, respectively. The experimental data indicated that the normal motion of cervical spines was a 3D coupled motion, especially in LB/RB direction, where a 35% rotation around X-axis existed. The cervical spine could recover close to normal coupled motion after TDR surgery. Conclusions TDR surgery can restore the physiological motion of cervical spines more close to the normal state, especially in Flex/Ext and LR/RR direction. The study provides a theoretical basis and quantitative reference for TDR and ACDF surgery in clinic.

Objective To measure and conduct statistic analysis of normal eyes by Pentacam. Methods Two hundred and twenty-one healthy people (442 eyes) underwent examinations of Pentacam, and they were divided into 5 groups by age: <40 years old group (50 people, 100 eyes), 40-49 years old group (50 people, 100 eyes), 50-59 years old group (50 people, 100 eyes), 60-69 years old group (50 people, 100 eyes) and >70 years old group (21 people, 42 eyes). Results With the increase of age, there were significant differences in chamber volume, chamber angle and anterior chamber depth among age groups (P<0.05). In elder age groups, there were significant differences in these parameters between males and females (P<0.01). Conclusion Anterior segment parameters are significantly correlated with age. After 60 years old, the anterior segment parameters become significantly different with gender.

OBJECTIVEIn mid-July 2005, five patients presented with septic shock to a hospital in Ziyang city in Sichuan, China, to identify the etiology of the unknown reason disease, an epidemiological, clinical, and laboratory study were conducted.

METHODSAn enhanced surveillance program were established in Sichuan, the following activities were introduced: active case finding in Sichuan of (a) laboratory diagnosed Streptococcus suis infection and (b) clinically diagnosed probable cases with exposure history; supplemented by (c) monitoring reports on meningococcal meningitis. Streptococcus suis serotype 2 infection was confirmed by culture and biochemical reactions, followed by sequencing for specific genes for serotype and virulence factors.

RESULTSFrom June 10 to August 21, 2005, 68 laboratory confirmed cases of human Streptococcus suis infections were reported. All were villagers who gave a history of direct exposure to deceased or sick pigs in their backyards where slaughtering was performed. Twenty six (38%) presented with toxic shock syndrome of which 15 (58%) died. Other presentations were septicaemia or meningitis. All isolates were tested positive for genes for tuf, species-specific 16S rRNA, cps2J, mrp, ef and sly. There were 136 clinically diagnosed probable cases with similar exposure history but incomplete laboratory investigations.

CONCLUSIONAn outbreak of human Streptococcus suis serotype 2 infections occurred in villagers after direct exposure to deceased or sick pigs in Sichuan. Prohibition of slaughtering in backyards brought the outbreak to a halt. A virulent strain of the bacteria is speculated to be in circulation, and is responsible for the unusual presentation of toxic shock syndrome with high case fatality.

OBJECTIVETo study the potential risk factors of human infecting with Streptococcus suis.

METHODS1: M matched case-control study was conducted. 29 human cases of Streptococcus suis infection in the early phase were included in the case group, Patients' family members, neighbors and peoples who had worked together with patients to handle deceased or sick pigs in the last week were recruited as matched controls. There were 147 controls in total. Both cases and controls received questionnaire investigation including the ways to contact sick/dead pigs. Conditional logistic regression was employed to analyze matching data.

RESULTSAccording to the results of multivariate analysis, slaughtering (OR = 11.978, 95% CI: 3.355-42.756), carcasses cutting and processing (OR = 3.008, 95% CI: 1.022-8.849) sick/dead pigs were associated with cases related to human Streptococcus suis infection. The attributable risk proportion were 91.65% and 66.76% respectively. The other types of exposures to sick/ dead pigs, including feeding, selling, burying and eating, were not associated with the human Streptococcus suis infection in our study population.

CONCLUSIONSlaughtering, carcasses cutting and processing sick/dead pigs were important risky behavior for humans to be infected by Streptococcus suis.
