ABSTRACT
Building a strong public health system has become an urgent task in the new era. Based on more than eight years of systematic research， we believe that five aspects need to be prioritized for a strong system. First， we should change the perspective on public health， using the word “gonggong jiankang” to replace “gonggong weisheng” and the word “gonggong jiankang tixi” to replace “gonggong weisheng tixi”， to lead the public health system development. Second， we should develop a suitable public health system and continuously improve the health capacity for governance. Third， we should make it clear that the goal of building a strong system is not far-fetched， and we need to consolidate the existing institutional advantages of China’s public health system： when encountering major problems， we can maintain a unified goal and mobilize the whole society to cooperate effectively to accomplish the goal. However， we need to make up for shortcomings one by one， especially to solve the key problem of lacking a strong coordination mechanism in daily work. Fourth， we should pursue excellence and consolidate the“suitable” mechanism proven in the process of coping with the COVID-19， so that efficient mechanisms to deal with major issues can be used in routine work， and efforts should be made to consolidate the advantages of prevention and control of infectious diseases and emergency response，so as to achieve the balanced development of regions categories and units.Finally， it is necessary to strengthen the coordination of government and research institutions， in the aspects of technological innovation， talent team building and accurate consulting services， and work together to pursue a suitable and strong system to realize the modernization of the health system and capacity for governance.
ABSTRACT
The outbreak of COVID-19 has exposed many shortcomings in disease control and prevention system (DCPS) of China.Resolving the problems and strengthening the DCPS became the top priority on China′s public policy agenda.This paper reveals the problems of the DCPS system regarding policy-making, regulations, operation mechanism and staff, and proposes several strategies from three aspects of legal construction, management system, and operation mechanism, including:"Prevention first" should be incorporated into the national legal system, all the departments should be engaged in "Healthy China 2030" initiative, laws and regulations should be amended, new disease prevention and control management institutions should be set up, a high-quality professional team should be retained, the regional health information exchange channels should be strengthened, the coordinated mechanism for disease prevention and control should be normalized, the long-term investment mechanism should be established, and the equipment renewal and reserve system should be improved.
ABSTRACT
Lysophosphatidic acid (LPA) is a small phospholipid that is present in all eukaryotic tissues and blood plasma. As an extracellular signaling molecule, LPA mediates many cellular functions by binding to six known G protein-coupled receptors and activating their downstream signaling pathways. These functions indicate that LPA may play important roles in many biological processes that include organismal development, wound healing, and carcinogenesis. Recently, many studies have found that LPA has various biological effects in different kinds of bone cells. These findings suggest that LPA is a potent regulator of bone development and remodeling and holds promising application potential in bone tissue engineering. Here, we review the recent progress on the biological regulatory function of LPA in bone tissue cells.

On the basis of systematic evaluation of 32 provincial capital cities and municipalities in their capacity for preventing and controlling emerging infectious diseases, focus analysis is made on Wuhan in relation to its advantages and disadvantages as follows:There has been a legal basis for epidemic prevention according to law, but it has not translated into effective action.There has been an organizational basis for responding to epidemic, but coordination mechanism has not been effectively established.The management mechanism has been complete, but the division of responsibilities among different departments has not been clear.The monitoring network has been set up, but its role of "predictive warning" has not been played.Insufficiency of public health service delivery was observed owing to lack of financial investment.In cities of China, advantages and disadvantages have been both existent in their capacity to prevent and control of emerging infectious disease.We should be vigilant in this regard. It is imperative to "fill defects, stop leaks and strengthen weakness".There is a Chinese saying:"It is not too late to mend a fold after the sheep have been stolen".

ABSTRACT
In the process of establishing Sprague Dawley rat skin grafting model, to prevent rats from biting and scratching the wounds is the key factor for determining success or failure. To solve this problem, the author designed a restraint material, which consists of neck film ring and limb dressing. It plays a good role in preventing rats from biting and scratching the wounds, and is worthy of popularization and application.

ABSTRACT
Currently, obesity has become a worldwide health problem and yet little is known about the impact of changes in obesity indicator on incident hypertension. The aim of this study was to compare the impact of changes in the WC and BMI on incident hypertension in a cohort population. After a baseline investigation, we conducted the first and the second follow-up assessments for subjects after 2 and 5 years, respectively. The associations between the changes in the WC and BMI [measured as the D-value, i.e., the value at the first follow-up minus the value at baseline] and the hazard ratio [HR] of incident hypertension were analyzed with a multilevel Cox proportional hazards regression model. Among 2778 participants without hypertension, 660 developed hypertension between the first and the second follow-up assessments. When both the BMI and WC D-values were included in the regression model, the WC D-value was a predictor of hypertension incidence in both sexes [OR= 1.03 and P values < 0.05 for men and women], but the BMI D-value was no longer a predictor of hypertension incidence in either sex [OR=1.04 for men and 1.01 for women, both P values >0.05]. In both sexes, hypertension risk was higher for subjects whose BMI was modified but WC was categorically increasing than for subjects whose WC and BMI were both modified. Both WC and BMI changes were associated with hypertension, but a change in the WC was a better predictor of the hypertension
ABSTRACT
<p><b>OBJECTIVE</b>To understand the distribution of marriage status among men who have sex with men (MSM) in the city of Changzhou, and to explore the impact of marriage on AIDS related high risk behaviors and HIV infection in this population.</p><p><b>METHODS</b>Target sampling (snowball sampling) was adopted to carry out a cross-sectional study, and structured questionnaire-based interviews were conducted to collect information on social demography, HIV related high risk behaviors. Blood and urine samples were collected to detect HIV, syphilis, gonorrhea and Chlamydia trachomatis infections.</p><p><b>RESULTS</b>Of the 655 participants, 37.4% were married. Married MSM mostly sought their sexual partners at the public bathing house (61.6%), while unmarried MSM were mainly through bars (33.6%) or internet (31.1%). The proportion of having anal sex with men during the last 6 months was lower in the married group (50.8%) than in the unmarried group (73.3%), (P < 0.001) The percentage of having sex with women in the last 6 months was significantly higher in the married group (68.9%) than that in the unmarried group (33.2%) (P < 0.001), (OR = 4.454, 95%CI: 3.168 - 6.261). The rates of condom use in the last anal sex with men in married and unmarried groups were 71.0% and 77.6%, respectively (P = 0.152). The rate of condom use in the last intercourse with women was significantly lower in the married group (44.0%) than that in the unmarried group (70.4%) (P < 0.001), (OR = 0.331, 95%CI: 0.205 - 0.535). In the sex trade, most of the married MSM would "buy" sex (66.7%), while unmarried MSM would "sell" sex (63.2%) (P < 0.05), (OR = 3.429, 95%CI: 1.255 - 9.366). The percentage of having drugs in the previous year was higher in married group (3.3%) than that in the unmarried group (0.8%) (P < 0.05). In married and unmarried groups, the infection rates of HIV, syphilis, gonorrhea and Chlamydia trachomatis appeared to be (8.6%, 8.6%), (17.1%, 12.3%), (1.6%, 2.4%), and (3.3%, 9.0%), respectively (P > 0.05).</p><p><b>CONCLUSION</b>Marriage seemed to have had limited effects on reducing the high risk behaviors of MSM. Different and multiform interventions should be developed according to the different characteristics of married or unmarried MSM population.</p>
