Objective To observe the therapeutic effect of Sanzi Yangqing Decoction (Decoction of three kinds of seeds) for mammary cystic hyperplasia.Methods Totally 113 patients with mammary cystic hyperplastia were randomized into a treatment group (58 cases) which was prescribed Sanzi Yangqing Decoction and a control group (55 cases) which was given Ruhe Sanjie Tablet (Tablet for dissolving mammary masses). Both were treated for 3 courses. Before and after treatment the clinical symptoms and signs, hormones in serum of both groups, and the indices of hemodynamics of the treatment group were observed.Results The total effective rate of the treatment group was 89.66%, while that of the control group was 65.45%, there was significant difference (P

0.05).Conclusion The expression of TM in different TCM syndromes of gastric carcinoma was different.There exists a certain relation in the expression of TM1 and TM2 in different TCM syndromes of gastric cancer.

One leading research target of modern tumor radiotherapy is to increase radiosensitization of tumor and improve curative effect of radiotherapy.Histone deacetylase inhibitors are epigenetic drugs that can play a part in radiosensitization through means of induction of apoptosis,inhibition of repair of DNA doublestrand breaks,cell cycle arrest,improvement of tumor cell hypoxia and increase of reactive oxygen species.There is an urgent need to develop biomarkers based on these pathways,which can promote clinically individualized treatment.

Objectives:To assess the nutritional status of retired residents in a community by mininutritional assessment(MNA) combined with anthropometry. Methods:MNA questionnaire and anthropometric parameters including waistline,hipline,height,weight,body mass index(BMI),midarm circumference,triceps skinfold(TSF) and midarm muscle circumference were performed in 115 retired residents. Results:①24 (20.9%) residents had MNA scores less than 23.5,which meaned malnutrition or at risk of malnutrition.②According to each single index,namely waistline, waist hip ratio and BMI,incidence of obesity was 53.9%,61.7% and 65.2% respectively.③According to each single index,that is,midarm circumference,TSF and midarm muscle circumference,prevalence of moderate or severe malnutrition was 1.7%,19.1% and 2.2%respectively.④There lied a significant correlation between MNA score and several anthropometric parameters. Conclusions:①Both overnutrition and undernutrition can be manifested in retired home residents,for whom nutritional intervene should be enhanced.②MNA questionnaire can be well used in Chinese.

Objective:To evaluate the effect of mechanical chest compression device in patients with cardiac arrest.Methods:The relevant literatures about mechanical cardiopulmonary resuscitation and manual cardiopulmonary resuscitation were systematically searched from China Knowledge Network (CNKI), VIP, Wanfang, PubMed, Web of Science and other databases. The effective data were extracted and analyzed by RevMan5.3 software.Results:A total of 20 clinical studies involving 29 727 patients were included, of which 11 104 patients received mechanical cardiopulmonary resuscitation and 18 623 patients received traditional manual cardiopulmonary resuscitation. The results of meta-analysis showed that mechanical cardiopulmonary resuscitation could not effectively improve the restoration of spontaneous circulation (ROSC) rate, admission survival rate, discharge survival rate and neurological prognosis in patients with cardiac arrest compared with manual cardiopulmonary resuscitation. ROSC occurrence rate ( RR=1.10, 95% CI: 0.99-1.23, P<0.01), admission survival rate ( RR=1.01, 95% CI: 0.95-1.08, P=0.67), discharge survival rate ( RR=1.00, 95% CI: 0.86-1.15, P=0.14), and good neurological function rate ( RR=0.81, 95% CI: 0.61-1.06, P=0.69) showed no significant differences between the mechanical cardiopulmonary resuscitation and manual cardiopulmonary resuscitation. Conclusions:Mechanical chest compression device has no advantage compared with manual cardiopulmonary resuscitation. Mechanical cardiopulmonary resuscitation is not recommended to completely replace manual chest compression in cardiopulmonary resuscitation.

Objective To explore the effects of antenatal premium care on the improvement of negative emotions and pregnancy outcomes for patients with gestational hypertension. Methods A total of 128 patients with gestational hyper-tension who were admitted to our hospital from June 2013 to January 2014 were selected as research subjects. They were randomly assigned to two groups, who received antenatal premium care (observation group) and regular nursing care (control group). SAS and SDS scores before and after admission, premature delivery, cesarean section, placental abruption, postnatal hemorrhage, eclampsia, pre-eclampsia, fetal distress, low birth weight, neonatal asphyxia, death, Apgar scores and life quality were compared. Results After antenatal premium care in the observation group, SAS and SDS scores were (41.42±5.16) and (40.29±5.41) respectively;After antenatal premium care in the control group, SAS and SDS scores were (50.27±5.49) and (48.73±5.63) respectively. Before the antenatal premium care, SAS and SDS scores between the two groups were not statistically significant (P>0.05). After the antenatal premium care, SAS and SDS scores in the observation group were significantly lower than those in the control group, and the differences were statis-tically significant (P<0.05). Differences of negative outcomes compared between the two groups of patients were statisti-cally significant (P<0.05). Differences of negative outcomes compared between the two groups of perinatal infants were statistically significant (P<0.05). Scores of life quality of patients in the observation group were all better than those in patients in the control group, and the differences were statistically significant (P<0.05). Conclusion Antenatal premium nursing is able to effectively ease the negative emotion of patients with gestational hypertension and enhance the out-come of mother and infants.

Objective To explore the efficacy of moderate dose bromocriptine by one-off oral administration in treatment of patients with non-acute prolactin (PRL) type pituitary adenoma.Methods Forty-three patients with definite diagnosis of non-acute prolactin type pituitary adenoma,admitted to our hospital from January 2016 to December 2017,were chosen in our study.All patients were administrated with 5 mg bromocriptine at 18 pm;the serum PRL levels were examined at 2,3 and 12 h after bromocriptine administration.The curative effects of these patients were judged by decline rate of PRL,and the curative effects of patients with different genders,different initial PRL levels and different ages were compared.Results In these 43 patients,bromocriptine showed excellent effect in 20 patients,obvious effect in 18 and invalid effect in 5.There were statistically significant differences in the efficacy of bromocriptine between different genders (P＜0.05).There were statistically significant differences in efficacy of patients with different genders after taking bromocriptine (P＜0.05).The female patients had obviously higher rate of obvious effect than the male patients.Patients with different initial PRL values had statistically significant differences in efficacy after taking bromocriptine (P＜0.05).Patients with PRL initial value of 40-200 ng/mL had significantly higher rate of obvious effect than patients with PRL initial value of ＞200 ng/mL.There was no significant difference in efficacy between patients ＜ 45 years old and patients＞45 years old (P＞0.05).Conclusion The treatment ofhyperprolactin caused by prolactin type pituitary adenoma with moderate dose bromocriptine by one-off oral administration is effective;female patients have obviously better effect than male patients;and for patients with initial prolactin＞200 ng/mL,the effect is better.

Objective:To study whether aspirin has inhibitory effect on microglia activation induced by Poly-IC and its mechanism.Methods:Microglia cell line BV2 were cultured in vitro to establish a Poly-IC stimulation-induced microglia cell immune activation model. The experiment groups were divided into control group (no treatment), model group (Poly-IC 10 μg/ml), high dose aspirin group (1 mmol/L aspirin), low dose aspirin group (0.1 mmol/L aspirin), high dose aspirin pretreatment group (Poly-IC 10 μg/ml + 1 mmol/L aspirin) and low dose aspirin pretreatment group (Poly-IC 10 μg/ml + 0.1 mmol/L aspirin). The phagocytosis ability of microglia cells, reactive oxygen species (ROS) and Iba1 protein expression were detected by using immunofluorescence method. The expression of the inflammatory cytokines Il-1β, Il-6, Il-10, TNF-α and cox-2 mRNA in microglia cells were detected by real-time quantitative PCR (RT-qPCR).Results:Compared with the control group, the morphology of microglia cells in model group changed significantly, and the phagocytosis ability and production of reactive oxygen species (ROS) increased. At the meantime, the expression of Iba1 protein was strongly decreased. In the model group, The mRNA expressions of IL-1β(20.55±1.92), IL-6 (63.98±7.83), TNF-α (16.84±3.19), COX-2 (6.78±0.42) were higher than IL-1β(1.01±0.14), IL-6 (0.95±0.17), TNF-α (1.22±0.38), COX-2 (0.87±0.11) in the control group. (Il-1β ( t=26.14), Il-6 ( t=10.22), TNF-α ( t=17.06) and COX-2 ( t=37.07), all P<0.01). In the aspirin pretreatment group, the phagocytic ability of microglia cells was inhibited compared with the model group, and the production of reactive oxygen species (ROS) reduced. The expression of Iba1 protein was also partly recovered. Meanwhile, the effect of the high aspirin dose pretreatment group on pro-inflammatory factors IL-1β(9.95±0.52), IL-6 (39.64±6.89), TNF-α(1.57±0.42), COX-2 (2.47±0.14)were lower than those in the model group significantly.(IL-1β: t=14.18, IL-6: t=3.69, TNF-α: t=16.68, COX-2: t=27.03, all P<0.01). Conclusion:Aspirin has an inhibitory effect on microglial activation induced by Poly-IC, which may be related with inhibiting the expression of inflammatory factors.

ObjectiveTo analyze the epidemic intensity and characteristics of influenza in Changzhou City， Jiangsu Province from 2019 to 2023， and to provide scientific evidence for the formulation of influenza prevention and control strategies. MethodsThe surveillance data of influenza surveillance sentinel hospitals in Changzhou City from April 2019 to March 2023 were collected through the China influenza surveillance information system. Influenza-like illness （ILI） cases before and after the pandemic of COVID-19 in Changzhou City were analyzed， and the differences among qualitative data were compared by using χ^² test. ResultsFrom April 2019 to March 2023 the percentages of ILI cases’ medical visits in the four-influenza surveillance year were 2.57%， 1.84%， 5.38%， and 3.66%， respectively， and the positive detection rates of influenza virus were 25.71%， 0.44%， 22.78%， and 24.32%， respectively. The number of influenza outbreaks was 61， 1， 23， and 128， respectively. ILI cases were mainly among adolescent children aged 5‒14 years. The percentage of ILI cases in 2020‒2021 after the pandemic of COVID-19 was significantly lower than that in 2019‒2020 （χ²=737.342， P<0.001）， and the percentage of ILI cases in 2021‒2023 was higher than that in 2019‒2020. Influenza viruses in 2019‒2021 were dominated by type B Victoria， and influenza A virus was the dominant strain in positive influenza virus detections in 2022‒2023. The number of influenza outbreaks in 2021‒2023 was significantly lower than that in 2019‒2020 （χ²=185.662， P<0.001）. ConclusionThe epidemiological characteristics of influenza are different in different stages of COVID-19 prevention and control during 2019‒2023. In the dynamic clearance phase of COVID-19， ILI case’s medical visits showed low-level fluctuations without obvious seasonal fluctuations， and influenza virus was dominated by type B. In the high-intensity phase of the pandemic， the level of ILI case’s medical visits has reached the peak of the calendar year， and the positive detection of influenza virus was dominated by type A H3N2. In the "Category B B control" phase， the level of ILI case’s medical visits increased after a rapid decline， and the positive detection of influenza virus was dominated by type A H1N1. It is necessary to further strengthen the monitoring of influenza cases， pay close attention to the changes in influenza strains， actively promote influenza vaccination for key population group， and promote health behavior changes for the whole population.
