ABSTRACT
Recently, among the edentulous patients who undergo dental implants, the proportion of hypertensive patients remains high, which poses a greater challenge for clinicians to operate and to maintain the therapeutic effect. The present review comprehensively summarized clinical researches about the adverse effects on dental implants, outlined molecular mechanisms of the positive effects of various antihypertensive drugs on bone metabolism, and proposed that clinicians should select preventive strategies during preoperative and intraoperative procedures according to the blood pressure of patients with hypertension.

We predicted the anti-hepatitis B virus (HBV) active components and mechanism of Salvia miltiorrhiza based on network pharmacology. The active components of S. miltiorrhiza were obtained through TCMSP, PubChem database and literature research. The potential targets of the active components and HBV infection were predicted by SwissTargetPrediction and GeneCards databases, respectively. The protein-protein interaction (PPI) network was constructed by String database. Cytoscape software was adopted to construct a visual network of active component-disease target and perform topological analysis. Gene Ontology (GO) and Kyoto Encyclopedia of Genes and Genomes (KEGG) pathway enrichment analyses were performed using DAVID platform. The molecular docking of key components and core targets was carried out by AutoDock Vina software. We screened out a total of 38 active components and 178 disease-component overlapping targets. Enrichment analyses obtained 405 related GO items and 68 signaling pathways, such as T/B cell receptor signaling pathways, PI3K/AKT signaling pathway, and mTOR signaling pathway. According to the results of molecular docking, most characteristic components of S. miltiorrhiza (miltionone Ⅱ, miltirone, protocatechuic acid, lithospermic acid, protocatechualdehyde) showed good affinity with the key targets (PIK3CA, APP, STAT3,AKT1 and mTOR). Furthermore, the anti-HBV activity of lithospermic acid, the representative active component of S. miltiorrhiza, and its regulation on PI3K/AKT and mTOR signaling pathways were investigated in an HBV replicating mouse model. Animal welfare and experimental procedures follow the regulations of the Animal Ethics and Welfare Committee of Hubei University. The results showed that lithospermic acid significantly inhibited HBV DNA replication, reduced serum HBsAg and HBeAg levels, and decreased the phosphorylation protein expression levels of AKT and mTOR in liver, indicating that lithospermic acid might exert the anti-HBV activity by regulating PI3K/AKT and mTOR signaling pathways.
ABSTRACT
Objective:To understand the epidemic status of patients with hypertension and diabetes among residents aged ≥35 years in Shanghai. Methods:The data of "Monitoring of Chronic Diseases and Behavioral Risk Factors in Shanghai in 2013" were used for analysis. Residents aged ≥35 years were selected to analyze the prevalence， awareness， treatment and control in patients with hypertension and diabetes. Results:The prevalence rate of patients with both hypertension and diabetes was 11.25% （95%CI：10.29%-12.29%） among residents aged ≥35 years in Shanghai. The older the age was， the higher the prevalence rated. The rate was the highest in urban area， second in rural area， and the lowest in urban-rural area. Education level of senior high school or above had lower rate than junior high school or below. The non-occupational group had the highest rate and the non-agricultural occupation group had the lowest. The widowed/separated/divorced groups had the highest rate and the married group had the lowest. The rate in obese people was the highest and normal people was the lowest. People with sleep time ≥6 h had a lower rate than those with sleep <6 h. All the above differences were statistically significant （χ2=890.98， 28.91， 61.92， 315.34， 123.72， 441.45， 8.77，all P<0.05）. The awareness rate was 50.09% （95%CI：46.54%-53.64%）， the highest in 60-74 years old group and the lowest in 35-44 years old group. The awareness rate in urban area was higher than that in the urban-rural junction， and the rural area was the lowest. The treatment rate was 45.67% （95%CI：42.45%-48.92%） and the age was proportional to the treatment rate. The treatment rate from high to low in order was city， urban and urban-rural junction， rural areas. The differences in age， region awareness rate and treatment rate were statistically significant （χ2=43.27， 35.19， 37.59， 37.56，all P<0.05）. Control rates was 6.45% （95%CI：5.17%-8.01%）， 60-74 age group had the highest， and the age group from 35 to 44 years old had the lowest， and the difference was statistically significant （χ2=20.35，P<0.05）. The treatment control rate was 14.11% （95%CI：11.54%-17.15%）. Conclusion:The prevalence rate of patients with co-existing hypertension and diabetes in Shanghai residents is high， the awareness rate and treatment rate are general， and the control rate is low. It is urgent to improve the comprehensive prevention and treatment level of patients with hypertension and diabetes.
ABSTRACT
Objective To predict the coronavirus disease 2019 (COVID-19) epidemic situation based on the infectious disease dynamics susceptible-exposed-infected-recovered (SEIR) model, so as to provide guidance for effective control of the epidemic. Methods Python crawler automatic update function was used to collect the epidemic data released by the National Health Commission of China. An improved infectious disease dynamics SEIR model, which can automatically correct the COVID-19 basic reproductive number (R0), was constructed to predict the development trend of COVID-19 epidemic in Hubei Province of China and South Korea. Results The peak of the COVID-19 epidemic in Hubei Province of China predicted by the model would appear on Feb. 21, 2020. The number of confirmed COVID-19 cases would be about 50 000 on Feb. 19 and would fall to below 30 000 on Mar. 4, and the epidemic would end on May 10. According to the actual data released by the National Health Commission of China, the peak number of confirmed COVID-19 patients was 53 371. The model predicted that an epidemic peak in South Korea would be on Mar. 7, and would end at the end of April. Conclusion This improved infectious disease dynamics SEIR model established in the early stage of COVID-19 epidemic has achieved relatively accurate prediction. The timely and effective intervention by relevant government departments has significantly affected the development of the epidemic. The epidemic situation in other countries in East Asia, such as South Korea, is still on the rise in March, suggesting that China needs to be on guard against the risk of imported epidemic.
ABSTRACT
OBJECTIVE@#To observe the dynamic change of anti-Müllerian hormone (AMH) in 1 year after chemotherapy which is the best biochemical marker of ovarian reserve in reproductive medicine setting and to evaluate the effect of gonadotropin-releasing hormone agonist (GnRHa)goserelin to prevent ovarian reserve function during (neo)adjuvant chemotherapy for young breast cancer patients.@*METHODS@#Between December 2015 and June 2017, 101 breast cancer patients of age ≤ 45 years with stages I to III had been enrolled. The patients were assigned without interference to receive either (neo) adjuvant chemotherapy with goserelin (goserelin group) or without goserelin (chemotherapy group) as their own selection. AMH and menstrual status were evaluated before, during and 0.5 year, 1 year after chemotherapy. Primary end point was the incidence of low AMH value (<0.4 μg/L) at the end of 1 year. Secondary end point was the incidence of amenorrhea (the absence of menses in the preceding 12 months after assignment).@*RESULTS@#In the study, 51 patients chose to join the chemotherapy group, while the other 50 patients selected goserelin to preserve their ovarian reserve function. More unmarried or childless, hormone receptors negative,receiving breast conservation therapy patients with earlier stage selected goserelin before chemotherapy. The incidence of low AMH value was significantly higher in chemotherapy group than in goserelin group (74.5% vs. 38.0%, P<0.001) in 1 year after chemotherapy. The incidence of amenorrhea was consistent with AMH (56.9% vs. 24.0%, P=0.001). And more patients' menstruation (78.9% vs. 54.5%) and AMH value (71.0% vs. 53.8%) recovered in goserelin group within 6 months after chemotherapy. In subgroup analysis, AMH and menstruation seemingly recovered more in goserelin group independent of age, chemotherapy regimen and use of tamoxifen. Especially, AMH value of 36.4% (8/22) patients in chemotherapy group and 18.4% (7/38) patients in goserelin group still maintained low level (<0.4 μg /L) although their menstruation had recovered 1 year after chemotherapy. In addition, 41 patients (20 patients in chemotherapy group, 21 patients in goserelin group) could be evaluated for the dynamic change of AMH and menstrual status during chemotherapy. The mean level of AMH in chemotherapy group declined rapidly to very low level before the 3rd cycle, while 70% of the patients kept presence of menstruation. At the same time, the mean level of AMH in goserelin group was still above 0.4 μg /L, but all of the patients had menopause.@*CONCLUSION@#Our study has offered evidence that Goserelin with chemotherapy could protect against ovarian reserve failure for young breast cancer patients, now that more patients' AMH value recovered earlier who had selected co-treatment. AMH may be a more precise marker than menstrual status to clinically evaluate ovarian reserve function pre-, during and post- chemotherapy.

[Objective]To investigate the influence of healthy walking intervention on risk factors of noncommunicable chronic disease in occupational population, and to explore the suitable mode of exercise intervention for occupational population in Shanghai. [Methods]Before and after healthy walking intervention were compared the changes of body weight, BMI, waist circumference, body fat rate, visceral fat index, over-weight and obesity rate, central obesity rate, blood-pressure controlling rate. [Results]Weight, BMI, waist circumference, body fat percentage, viscera index, SBP and DBP all reduced after100 days of healthy walking, and the results were (1.52 ± 2.75) kg (Z =-21.99, P < 0.01) , (0.55 ±1.03) kg/m2 (Z =-21.64, P<0.01) , (2.10±5.27) cm (Z =-17.62, P<0.01) , (0.31±4.59) ％ (Z=-3.48, P < 0.01) , (0.12 ± 1.99) (Z =-2.70, P < 0.01) , (2.51 ± 10.87) mm Hg (Z =-9.35, P <0.01) and (1.67±8.26) mm Hg (Z =-9.06, P < 0.01). The rate of over-weight and obesity decreased7.86％, the rate of central obesity decreased 6.92％, and the rate of blood-pressure controlling increased2.72％. There were significant difference between the three indicators before and after healthy walking (χ2= 916.48, P< 0.01; χ2= 585.90, P < 0.01; χ2= 366.37, P < 0.01). [Conclusion] Healthy walking could reduce occupational population' s over-weight and obesity rate, central obesity rate, and increase blood-pressure controlling rate. The risk factors of un-communicable chronic disease have improved significantly. Healthy walking plays a positive role in the prevention and control of chronic diseases.
ABSTRACT
BACKGROUND/AIMS: A large number of studies have shown that function constipation (FC) has an extremely high incidence of mental and psychological disorders. Cranial electrotherapy stimulation (CES) was applied to the treatment of psychological disorders such as anxiety and depression. We explored the effects of CES combined with biofeedback therapy (BFT) on the psychological state, clinical symptoms, and anorectal function in patients with FC. METHODS: A total of 74 patients with FC were randomly divided into 2 groups. The control group received BFT. CES combined with BFT was carried out in the experiment group. All patients were assessed using the self-rating anxiety scale (SAS), self-rating depression scale (SDS), and Wexner constipation score at baseline and the end of each course. Anorectal manometry and balloon expulsion tests were performed before and after treatment. RESULTS: After treatment, the participants in the experiment group had significantly lower score SAS, SDS, and Wexner constipation scores than the control group (all P < 0.05). The number of successful expulsion in the experiment group was larger than the control group (P = 0.016). CONCLUSIONS: CES combined with BFT was effective in improving the psychological status of anxiety, depression, and bowel symptoms in patients with FC.

Low pressure, low oxygen concentration, and intense ultraviolet (UV) radiation in high-altitude environments, can cause oxidative stress which can trigger mountain sickness. A recent study demonstrated that hydrogen gas with a good permeability in biological membranes can treat various disorders by exerting its selective anti-oxidation and anti-inflammatory effects, indicating that hydrogen therapy plays a role in scavenging free radicals and in balancing oxidation and anti-oxidation systems of cells. Therefore, we hypothesize that inhaling low-dose hydrogen or drinking hydrogen-saturated water is a novel and simple method to prevent and treat oxidative stress injury caused by low pressure, low oxygen concentration and intense UV radiation in plateaus, thus reducing the risk of mountain sickness.

<p><b>OBJECTIVE</b>To study the Th17/Treg (regulatory T cells) immunoregulation in patients coinfected with TB and HIV before and after HAART(highly active anti-retroviral therapy).</p><p><b>METHODS</b>10 HIV cases coinfected with TB (HIV/TB group) and 10 cases infected with HIV only (HIV group) received HAART. PBMCs were stained and immunophenotyping of Th17 (IL-17 expressing T cells) and CD4+ CD25 T cells (Treg) were analysed by flow cytometry.</p><p><b>RESULTS</b>The pre-treatment patients tended to have lower Th17 cells and higher Tregs cells compared to post-treatment (1.90% +/- 0.9% vs. 4.65% +/- 1.48%, 16.48% +/- 4.91% vs. 8.29% +/- 3.13% respectively). The percentage of IL-17 before and after HAART were 1.90 +/- 0.9% vs. 4.65 +/- 1.48% respectively in HIV/TB group patients (P < 0.01). The difference between the percentage of IL-17 before and after HAART in the HIV/TB group and the HIV group were 2. 65 +/- 1.62% vs. 0.67% +/- 0.46% respectively (P < 0.01). IL-17 expressing T cells were increased faster after HAART in the former group than the latter. The percentage of Treg before and after HAART were 16.48% +/- 4.91% vs. 8.29% +/- 3.13% respectively in HIV/TB group (P < 0.01). The difference between the percentage of Treg before and after HAART in the HIV/TB group and the HIV group were 8.91% +/- 4.82% vs. 2.63% +/- 2.34% respectively (P < 0.01). Treg were decreased more rapidly after HAART in the former than the latter.</p><p><b>CONCLUSIONS</b>TB and HAART both had an effect on the Th17/Treg ratio of HIV/ TB co-infected patients, which can cause increased Th17 expression, the later plays a pro-inflammatory role. TB and HAART can decrease Treg expression and enhance anti-inflammation response. The fact that Th17/ Treg disorder are more likely to exist in patients with HIV/TB co-infection after HAART for one month suggests a potential role for Th17/Treg imbalance leading to tuberculosis-associated immune reconstitution inflammatory syndrome during patients receiving HAART period.</p>
