Health management is the intrinsic requirement to build and embody a harmonious society. While health management provides strong human resources for the development of a harmonious society, a harmonious society promotes the health management. Health management plays a significant role in the construction and development of a harmonious society in terms of reducing risks to the health, improving the quality of life, lowering medical cost, lightening the socio-medical burden, enhancing awareness of health, improving the national health conditions, protecting health resources, and promoting a sustainable social development. Health is an important component of social productive forces, and health management is an essential prerequisite for the harmonious development of society. There would be no real harmonious society without effective health management.

Objective To evaluate the effect of curcumin on spinal inflammatory factor in rats with diabetic neuropathy. Methods Diabetic neuropathy was induced by intraperitoneal injection with 1% STZ (60 mg/kg) in sprague-dawley rats. These diabetic rats were randomly allocated to diabetic group (D group, n=10) and curcumin group ( C group , n = 10 ) . Another 10 age-matched normal rats served as controlled group ( N group , n = 10 ) . 28 days after STZ injection, the rats in C group received daily intragastric administration of curcumin (200 mg/kg) whereas those in D group received the same volume of normal saline for 2 weeks. Caudal vein blood glucose levels at T1( before STZ injection)and at T2-T8(2、7、14、21、28、35、42 days after STZ injection)from all rats were detected. Responses to the mechanical stimulus were measured with von Frey filament, and paw withdraw threshold (PWT) was recorded at T1 and at T3 to T8. At T8,the rats were killed and lumbar segments of spinal cord were removed to detect TNF-αand IL-6 content. Results Compared to N group, rats in both C and D group showed hyperglycemia at T2 to T8 (P<0.05) and lower PWT at T4~ 8 (P < 0.01). Compared to D group, C group showed higher PWT at T7,8(P<0.05). Both D and C group showed higher levels of blood sugar at T2 ~ 8 than that at T1 (P < 0.05). C group showed higher PWT at T7,8 than that at T6(P<0.05). Compared to N group,spinal TNF-αand IL-6 content increased in both D and C groups (P<0.05). Compared to D group, C group had reduction of TNF-αand IL-6 concentration (P < 0.05). Conclusion Curcumin can attenuate diabetic neuropathic pain on rats probably by reducing inflammatory factor in spinal cord.

Liver fibrosis occurs as compensatory responses to tis-sue repairing process in a wide range of chronic liver injures.It is characterized by excessive deposition of extracellular matrix (ECM)in liver tissues.The new discovery shows that suppres-sor of cytokine signaling (SOCS-3)is strictly associated with fi-brogenic progression of chronic liver diseases.Recent basic and clinical investigations also demonstrate that liver fibrogenesis is accompanied by SOCS-3,which critically determines the patho-
genesis and prognosis of liver fibrosis.This review summarizes current knowledge on SOCS-3 and the relationships between SOCS-3 and liver fibrosis.On the other hand,it also presents the different strategies that have been used in experimental mod-els to counteract excessive SOCS-3 and the role of SOCS-3 in the prevention and treatment of liver fibrosis.

Objective:To explore the influence of rosuvastatin in the lipid levels, atherosclerosis plaque and apoptosis in the plaque of atherosclerotic apolipoprotein E (ApoE)-knockout mouse models, and to clarify the mechanism of rosuvastatin in inhibiting atheromatous plaque and apoptosis in the plaque.Methods:Thirty healthy six-week old male mice were randomly divided into high fat diet group (n=10),rosuvastatin group (n=10)and general diet control group (n=10).The mice in first two groups were fed with high fat diet,and the mice in general diet control group were fed with general diet;4 weeks later the mice in three groups were respectively given 0.9% NaCl solution,rosuvastatin (10 mg·kg·d-1 )and 0.9% NaCl solution by gavage for 8 weeks.And then ELISA was used to detect the serum lipid levels,the area of atherosclerotic plaque was measured by HE staining, and the apoptosis in plaques was detected by TUNEL method;the expression of apoptosis-assoicated gene Bax protein was measured by immunohistochemical staining.Results:Compared with high fat diet group,the levels of total cholesterol (TC)and low density lipoprotein cholesterol (LDL-C)of the mice in rosuvastatin group were significantly decreased (P<0.05 or P<0.01),and the 1evel of high density lipoprotein cholesterol (HDL-C)was significantly increased (P<0.01).The aortic atherosclerotic plaque of the mice in high fat diet group was massive with a great quantity of foam cells, cholesterol crystal, necrotic cells and inflammatory cells in the plaque;the aortic atherosclerotic plaque of the mice in rosuvastatin group was smaller with less foam cells,necrotic cells and inflammatory cells;the aortic atherosclerotic plaque area of the mice in rosuvastatin group was significantly smaller than that in high fat diet group (P<0.01);the apoptotic index in the aortic atherosclerotic plaque of the mice in rosuvastatin group was significantly lower than that in high fat diet group (P<0.01).Compared with high fat diet group,the expression of Bax protein in rosuvastatin group was significantly decreased.Conclusion:Rosuvastatin may inhibit the progression of atherosclerotic plaque and the apoptosis in plaques through mitochondrial pathway.

Objective To evaluate the effect of intrathecal rapamycin on diabetic neuropathic pain in rats.Methods Thirty adult male Sprague-Dawley rats,weighing 180-220 g,in which IT catheters were successfully implanted,were randomly divided into 5 groups (n =6 each) using a random number table:control group (group C),diabetic neuropathic pain group (group DN),rapamycin 1 μg group (group R1),rapamycin 3 μg group (group R3) and rapamycin 10 μg (group R10).Diabetes mellitus was induced by intraperitoneal streptozotocin (STZ) 60 mg/kg on 5 days after IT catheters were implanted in DN,R1,R3 and R10 groups.Citric acid-sodium citrate buffer 6 ml/kg was injected intraperitoneally in group C.In R1,R3 and R10 groups,rapamycin (dissolved in 10 μl 4％ dimethyl sulfoxide) 1,3 and 10 μg were intrathecally injected,respectively,once a day for 7 consecutive days starting from day 21 after STZ injection,while the equal volume of 4％ dimethyl sulfoxide was given instead in C and DN groups.Paw withdrawal threshold (PWT) to yon Frey filament stimulation was measured before IT catheters were implanted,before STZ injection,on 7,14 and 21 days after STZ injection,and on 1,3,5 and 7 days after rapamycin administration.After measurement of PWT,the rats were sacrificed and L2-5 segments of the spinal cord were removed for determination of the expression of mTOR and phosphorylated mTOR (p-mTOR),S6K and phosphorylated S6K (p-S6K) (by Western blot) and expression of mTOR mRNA and S6K mRNA (by RT-PCR).Results Compared with group C,MWT was significantly decreased at 14 and 21 days after STZ injection in DN,R1,R3 and R10 groups,and the expression of mTOR,p-mTOR,S6K,p-S6K,mTOR mRNA and S6K mRNA was up-regulated in group DN (P ＜ 0.01).Compared with group DN,MWT was significantly increased at 5 and 7 days after rapamycin administration in group R1,at 3,5 and 7 days after rapamycin administration in group R3,and at 1,3,5 and 7 days after rapamycin administration in group R10,and the expression of mTOR,p-mTOR,S6K,p-S6K,mTOR mRNA and S6K mRNA was down-regulated in R1,R3 and R10 groups (P ＜ 0.01).Conclusion Intrathecal rapamycin can alleviate diabetic neuropathic pain in rats.

Farnesoid X receptor ( FXR) plays a key role in me-tabolism of substance, such as bile acid, lipid, glucose,( etc) . Newly published credible discoveries have claimed that as a reg-ulatory hub in metabolism, FXR is closely linked with diverse chronic liver diseases, including viral hepatitis, alcoholic fatty liver disease, nonalcoholic fatty liver disease, hepatic fibrosis and hepatocellular carcinoma. This review summarizes the roles and mechanisms of FXR during the courses of chronic liver dis-eases, aiming at providing novel insights and therapeutic target for antifibrotic research and drug development.

Abstract: Heterologous boost COVID-19 vaccination can solved the problem of decreased efficacy caused by single dose of vaccine. Heterologous booster with adenoviral-vectored COVID-19 vaccine (Ad5-nCoV) following primary immunization with inactivated COVID-19 vaccines is a widely-used vaccination strategy in clinic, while different routes of Ad5-nCoV administration exist and pose a question which route could be more optimal. In this study, we comprehensively evaluated and compared the vaccine immunity induced in mice immunized according to three different vaccination regimens: “3×phosphate buffered solution(3× PBS)”, “2×inactivated vaccine + 1×inactivated vaccine (3×INA)”, “2×inactivated vaccine + 1×Ad5-nCoV (intramuscular)[2×INA+Ad5(im)]”and“2×inactivated vaccine + 1×Ad5-nCoV (intranasal)[2×INA+Ad5(in)]”. We found that heterologous booster with Ad5-nCoV, irrespective of the route of administration, induced significantly higher levels of anti-Spike IgG and subclasses (IgG1and IgG2c), Spike-specific T cells, class-switched Spike+ memory B cells (MBCs) than homologous booster with 3rd dose of inactivated COVID-19 vaccine. Of note, compared with the intramuscular given, intranasal given of Ad5-nCoV as a booster dose clearly induced higher levels of serum and bronchoalveolar bavage fluid anti-spike immunoglobulin A, and moreover, induced stronger infiltration of major innate effector cells like neutrophils, natural killer cells and dendritic cells into the lung tissue, which suggested that mucosal vaccine responses are generated upon intranasal booster with Ad5-nCoV. Altogether, our study analyzed the vaccine immunity induced by different COVID-19 vaccines administered using different regimens, which may guide the clinical use of other types of prophylactic vaccines aiming to mount improved vaccine responses.

OBJECTIVETo observe the change of neuronal nitric oxide synthase (nNOS) expression in the spinal cord of diabetic rats with painful diabetic neuropathy.

METHODSSixty SD rats were randomized equally into painful diabetic neuropathy group (DM group) and control group. Painful diabetic neuropathy was induced by intraperitoneal injection with STZ (60 mg/kg) in DM group, and the rats in the control group received a solvent injection. Blood glucose levels were measured before and at 2, 7, 14, 21, and 28 days after STZ injection (T1-6 respectively). Responses to the mechanical stimulus were measured with von Frey filament, and 50% paw withdraw threshold (PWT) and body weight were recorded at T1 and T3-6. At T1 and T3-6, 6 rats from each group were sacrificed to examine the expression of nNOS in the lumbar segments of the spinal cord using Western blotting.

RESULTSThe level of blood glucose increased while the body weight decreased significantly after STZ injection in DM group (P<0.05). Comparing to those in the control group, PWT decreased while spinal nNOS expression increased significantly in DM group at T4-6 (P<0.05) showing an inverse correlation between them (P<0.01).

CONCLUSIONThe enhanced expression of spinal nNOS might be involved in the pathogenesis of painful diabetic neuropathy in rats.

Objective:To analyze the clinical characteristics and prognosis of pregnant women with hemorrhagic fever with renal syndrome (HFRS).Methods:A total of 11 pregnant women with HFRS admitted to The Second Affiliated Hospital of Xi′an Jiaotong University (four cases), The Second Affiliated Hospital of Air Force Medical University (four cases), The First Affiliated Hospital of Xi′an Jiaotong University (one case) and Central Hospital of Xianyang City (two cases) between November 2009 and February 2019 were included as the study group, and 24 age-matched non-pregnant women with HFRS were selected as the control group. The age, complications, clinical classification and laboratory indexes of the two groups were analyzed retrospectively, and the clinical outcomes of pregnant women and their fetuses in the study group were followed up. The data between two groups were compared using Mann-Whitney U test or chi-square test. Results:Patients in the study and control groups were 29 (22, 33) and 32 (24, 37) years old, respectively. Seven of 11 patients in study group were severe and critical cases, which was significantly higher than that in the control group (16.7%(4/24), χ2=7.722, P=0.015). In the study group, 10 patients had hypervolemic syndrome, 10 patients had pulmonary edema and six patients had overlapping hypotension shock phase and oliguria phase, which were all higher than those in the control group ((2/24, 8.3%), (2/24, 8.3%) and (2/24, 8.3%), respectively; χ2=22.828, 22.828 and 9.135, respectively, all P<0.01). Compared with the control group, the pregnant patients in study group had a higher urea nitrogen maximum and serum creatinine maximum, and the differences were both statistically significant ( Z=-2.453 and -2.336, respectively, both P<0.05), while they had a lower serum albumin minimum, hemoglobin maximum and hemoglobin minimum, and the differences were all statistically significant ( Z=-3.742, -3.350 and -4.034, respectively, all P<0.01). All pregnant women with HFRS recovered. Nine pregnant women gave birth to nine healthy infants. All of them received breastfeeding and the feeding duration were more than six months. No abnormal growth and development were found during an average follow-up of three years. Conclusions:Pregnancy can aggravate the severity of HFRS, and pregnant women have higher risk of the multiple stages overlap and the complications such as hypervolemic syndrome and acute pulmonary edema. After recovery from HFRS, mother may carry to full-term pregnancy.
