Objective : To investigate the status and influencing factors of home blood pressure monitoring (HBPM) among hypertensive patients, so as to provide the evidence for building and maintaining HBPM among hypertensive patients. Methods: Hypertensive patients hospitalized in the First Affiliated Hospital of Guangdong Pharmaceutical University were sampled from July to December 2022, and subjects' general data, HBPM behaviors and cognition were collected using self-designed questionnaires. In addition, factors affecting regular HBPM were identified using a multivariable logistic regression model. Results: Totally 440 questionnaires were allocated, and 422 valid questionnaires were recovered, with an effective recovery rate of 95.91%. The respondents included 234 males (55.45%) and 188 females (44.55%), and had a median age of 70 (interquartile range, 15) years. There were 239 respondents with regular HBPM (56.64%). Of 422 respondents, 68 had good cognition of blood pressure monitoring (16.11%), and 79.15% did not think regular changes of their blood pressure within 24 hours, while 72.04% did not think it necessary to measure blood pressure more than twice a day. Multivariable logistic regression analysis showed that recommendation of regular blood pressure monitoring by healthcare workers (OR=4.341, 95%CI: 2.493-7.560), number of blood pressure measurements according to real circumstances (OR=3.858, 95%CI: 1.358-10.961), recording of measurement results (OR=4.945, 95%CI: 1.863-13.129), provision of data to doctors at admission (OR=2.023, 95%CI: 1.173-3.488) and good cognition of blood pressure monitoring (good, OR=11.939, 95%CI: 3.972-35.886; general, OR=9.681, 95%CI: 5.157-18.172) resulted in a high possibility of regular HBPM among respondents. Conclusion Hypertensive patients with recommendation of regular blood pressure monitoring by healthcare workers, number of blood pressure measurements according to real conditions, recording of blood pressure measurement results, provision of blood pressure to doctors at admission and good cognition of blood pressure monitoring are more likely to have regular HBPM.

Objective To compare clinical effect of gonadotropin releasing hormone agonist(GnRH-a) alone and GnRH-a combined with low-dose dydrogesteronea and estradiol valerate on sex hormone, hypoestrogenic symptoms, quality of life and bone mineral density (BMD)in treatment of endometriosis.Methods Seventy patients with moderate or severe endometriosis, who were diagnosed by laparotomy or laparoscopic surgery within two months, were randomly assigned into two groups.35 patients in GnRH-a group were treated by goserelin (3.6 mg)for three months, and 35 patients in add-back group were treated by goserelin (3.6 mg)combined with estradiol valerate 0.5 mg and dydrogesteronea 5 mg daily.Before and after the treatment, clinical parameters were recorded and analyzed, including visual analog scale (VAS), medical outcomes survey short form 36 (SF-36), Kupperman menopausal index(KMI), BMD, the serum level of follicle stimulating hormone (FSH), estradiol (E_2) and bone gla-protein (BGP) .The first menstruation and VAS were also followed up after treatment.Results Every 3 cases in two groups lost follow-up.(1)Reproductive hormone: the level of E_2 in add-back group [(94 ± 71) pmol/L]was significantly higher than (54±52) pmol/L in GnRH-a group(P <0.01).The level of FSH in add-back group [(3.0 ± 1.9) U/L]was significantly lower than (5.7 ± 2.9) U/L in GnRH-a group (P < 0.05).(2) VAS: after treatment, VAS in both group decreased significantly when compared with that before treatment(P < 0.05), and remained until menstruated.(3) KMI: KMI in add back-group (10 ± 8) was significantly lower than (14 ± 6) in GnRH-a group (P < 0.05).(4) BMD: compared with that before treatment, BMD decreased significantly after treatment in GnRH-a group (P < 0.05), no remarkable difference of BMD was observed before and after treatment in add-back group.Before treatment, serum BGP in both groups did not show statistical difference.After treatment, the level of BGP in GnRH-a group [(7932±5206) ng/L]was significantly higher than (5419±2917) ng/L in add-back group (P <0.05).Conclusions GnRH-a combined with estrogen-progesterone regimen could relieve pain from endometriosis as effectively as GnRH-a alone and reduce hypoestrogenic symptoms and bone loss.Therefore,it is a safe and effective treatment.

Objective To evaluate antimicrobial effect and mechanism of meropenem in the model of PA infection by C.elegans.Methods To evaluate drug effects of PA infection with caenorhabditis elegans by different concentrations of culture medium, determinate the lethal rate of C.elegans.Western blot detected mitogen activated protein kinase ( Mitogen-activated protein kinase MAPK ) activity change, and PCR detected antimicrobial peptide genes expression in C.elegans after PA infection,the effect of meropenem on MAPK activity change and antimicrobial peptide genes expression.Results Compared with the control group (OP-50), the death rate of C.elegans in PA infection group changed significantly (P<0.01). Meropenem showed protective effect after C.elegans infection ( P <0.01 ) .Detection of MAPK kinase activity showed that PA infection caused PMK-1 kinase activation, further study showed that antibiotics meropenem did not affect the activation of PMK-1 kinase (no significant difference).C.elegans antimicrobial peptide gene Lys-1, clec-85, F55G11.7, K08D8.5 activity increased in PA infection (P<0.01).Meropenem promoted the expression of the antimicrobial peptide gene increased (P<0.01),with synergistic effects.Conclusion Our results show that a C.elegans pathogenicity model can be applied screening drug susceptible to pathogens infection quickly and easily.

Objective:To evaluate the value of vasoactive-inotropic Score (VIS) at different time points in predicting the 28-day mortality of patients with septic shock, so as to reduce the risk of death and improve the prognosis of patients.Methods:This experiment was a single-center retrospective cohort study. The clinical data of 275 adult patients with septic shock who were treated with vasoactive drugs in the intensive care unit of the Affiliated Hospital of Xuzhou Medical University from February 2016 to February 2020 were collected. According to the 28-day survival condition, all recruited patients were divided into the death group and the survival group, and the maximum vasoactive-inotropic score of all patients at the first 24 h and the second 24 h were calculated, which were expressed as VIS max24 and VIS max48. Multivariate logistic regression analysis was used to find the independent risk factors that influencing the prognosis. The receiver operating characteristic curve was used to analyze the predictive value of VIS. Results:There was no significant difference between the death group and the survival group in the characteristics including age, sex, weight, infection sites, blood culture results, cardiac arrest, hormone use, and 24 h rehydration volume ( P>0.05). APACHE II score, basic lactic acid, and lactic acid after 24 h of treatment were increased significantly in the death group ( P<0.05). VIS max24 could accurately predict the 28-day mortality (AUC=0.953, 95% CI: 0.924-0.982), which were more efficent compared to VIS max48 (AUC=0.919, 95% CI: 0.881-0.957), basic lactic acid (AUC=0.937, 95% CI: 0.900-0.966) and APACHEⅡ score (AUC=0.865, 95% CI: 0.818-0.913). Conclusion:VIS max24 can more accurate predict the 28-day mortality in patients with septic shock.

Acupoint compatibility is a basic element for acupuncture prescription and an important link for clinical acupuncture workers to obtain a therapeutic effect. Studying factors influencing the effect of acupoint combination and ascertaining its concept and connotation are of important significance for studying the mechanism of acupuncture action. By sorting out, summing up and analyzing relevant modern literature, it is found that factors influencing the effect of acupoint combination are those affecting the therapeutic effects of combination of two or more than two acupoints. Its contents include five aspects: combination mode, combination effect, stimulation method, time factor and body status. Analysis and induction show that acupoint selection is the primary task in studying factors influencing the effect of acupoint combination.

Primary insomnia (PI) is now a nonorganic sleep disorder that seriously affects the quality of life of people around the world and attracts the attention of medical circles at home and abroad. Western medicine treatment has side effects such as drug dependence and withdrawal rebound and cannot obviously improve the quality of sleep and life, while acupuncture has a good therapeutic effect on PI. This article explores the latest research status of acupuncture treatment for PI. Chinese Journal Net (CNKI, VIP and Wanfang) was mainly searched to retrieve and sum up recent five years’ literature about the study of acupuncture treatment for PI. The results show that acupuncture has an advantage in producing a short-term marked therapeutic effect on PI and being of a high total efficacy rate and can effectively treat primary insomnia.

[ ABSTRACT] AIM:To observe the effect of ginsenoside Rb 1 on the proliferation and the expression of serotonin transporter (SERT), 5-hydroxytryptamine 1B receptor (5-HT1BR) in rat pulmonary artery smooth muscle cells (PASMCs) under hypoxia condition and the relationship with Rho /Rho-kinase signal pathway .METHODS: PASMCs were isolated from the adult male SD rats and primarily cultured .The subcultured cells from the 4th generation to the 6th generation were harvested and divided into normal group , and hypoxia group , different concentrations of Rb 1 incubation groups treated with 50, 100 and 200 mg/L ginsenoside Rb1 under hypoxia (HR50, HR100 and HR200 groups, respectively).The viability of the PASMCs was measured by CCK-8 assay.BrdU positive cells were determined using flow cytometry .The expression of serotonin transporter and 5-HT1BR at mRNA and protein levels was detected by RT-PCR and Western blot, respectively. The PASMCs were randomly divided into normal group , hypoxia group , HR200 group and hypoxia +Y-27632 incubation group ( HY group ) .The mRNA expression of Rho-kinase and phosphorylated myosin phosphatase target subunit 1 ( p-MYPT1) protein level were investigated by RT-PCR and Western blot, respectively.RESULTS: Compared with normal group, the proliferation of PASMCs in hypoxia group was significantly increased (P<0.01).The cell viability and the ex-pression of SERT and 5-HT1B R at mRNA and protein levels in all different concentrations of Rb 1 groups were obviously de-creased compared with hypoxia group ( P<0.05 ) .The mRNA expression of Rho-kinase and protein level of p-MYPT1 were markedly decreased in HR200 group, and no significant difference compared with HY group was observed ( P <0.01).CONCLUSION: Treatment with ginsenoside Rb1 might prevent hypoxia-induced proliferation of PASMCs and over-expression of SERT and 5-HT1B R through inhibiting the Rho/Rho-kinase pathway .
