ObjectiveTo observe the clinical efficacy and safety of Bushen Ruyan Formulation （补肾乳岩方， BRF） in treating premenopausal breast cancer patients of disharmony of the chong （冲） and ren （任） meridian type under endocrine intensive therapy. MethodsA total of 88 premenopausal breast cancer patients who received endocrine intensive therapy and were diagnosed with disharmony of the chong and ren meridian by traditional Chinese medicine （TCM） were included and randomly divided into a control group and a treatment group， with 44 cases in each group. The control group received ovarian function suppression （OFS） combined with endocrine therapy， while the treatment group was given oral BRF additionally. Both groups were treated for three months. The clinical efficacy was evaluated by comparing the pre- and post-treatment results of the Functional Assessment of Cancer Therapy-Breast （FACT-B）， modified Kupperman score， T cell subsets （CD3⁺， CD4⁺， CD8⁺， CD4⁺/CD8⁺）， sex hormone levels， including estradiol （E₂）， luteinizing hormone （LH）， follicle-stimulating hormone （FSH）， progesterone （P）， testosterone （T）， and prolactin （PRL）， tumor markers， such as carcinoembryonic antigen （CEA）， carbohydrate antigen 125 （CA125）， and carbohydrate antigen 153 （CA153）， TCM syndrome score， and TCM syndrome efficacy. Blood routine tests， liver function and kidney function were monitored to assess safety. ResultsThe FACT-B scores of each domains and the total scores of the treatment group increased， while the social/family status score of the control group decreased. The treatment group had significantly higher scores in all domains and total score compared to the control group （P＜0.05 or P＜0.01）. The modified Kupperman score and TCM syndrome score of the treatment group decreased， and were lower than those of the control group （P＜0.01）. The levels of CD3⁺ and CD4⁺ in the treatment group increased， and were higher than those of the control group （P＜0.05）. Serum testosterone levels in the treatment group were lower than those in the control group （P＜0.05）. The total effective rate of TCM syndrome efficacy in the treatment group was 67.44%， significantly higher than the 23.26% in the control group （P＜0.05）. No significant abnormalities were observed in the blood routine tests or liver/kidney function indicators in either group before or after treatment. ConclusionBRF can effectively improve quality of life， alleviate symptoms， increase serum CD3⁺ and CD4⁺ levels， and enhance clinical efficacy in premenopausal breast cancer patients undergoing endocrine intensive endocrine therapy. It is also safe with no significant adverse effects.

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.

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 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.

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 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.

A 57-year-old male patient received oral sorafenib 400 mg twice daily for pulmonary metastases after operation of thyroid carcinoma. About 3 and a half months of treatment,the patient experienced dizziness,pain in the anterior region of the heart and blood pressure of 180 / 105 mmHg(before treatment it was 120 / 75 mmHg). He received oral metoprolol administration(initial dose of 25 mg twice daily,gradually increased to 200 mg twice daily). About one and a half months later,he received sustained release capsules of isosorbide mononitrate 50 mg once daily because of the intermittent attack of precordial pain. Angina pectoris still occurred frequently. He underwent percutaneous coronary intervention twice(a total of 2 stents implantation). Hypertension and angina pectoris were still poorly controlled. On month 19 of sorafenib treatment,the dose of drug was reduced to 400 mg once daily. His blood pressure was 135 / 85 mmHg but angina still occurred intermittently. On month 22,sorafenib was stopped. Two months later,the patient's blood pressure declined to 130 / 80 mmHg,and the frequency of angina pectoris decreased. Four months after the termination of sorafenib,his blood pressure was 120 / 75 mmHg and no episode of angina pectoris occurred.
