CONCLUSIONS:The relevant departments should establish and improve the quality standard system of TCM decoction piece,and clear the varieties of TCM decoction piece in the National Essential Medicine List,perfecting supporting policies such as medicare reimbursement and attaching importance to the training of professional talents can ensure scientific and rational services for the public health.

Objective:To study the effects on lymphocyte & T subset of SARS patients treated by integrative traditional Chinese and western medicine(ICWM). Methods:48 patients were randomly divided into two groups, the control group treated by western medicine (WM) alone and the test group treated by ICWM. The test group patients took the traditional Chinese medicine by 3 weeks based on their conditions. Lymphocyte and T subset were measured. Results:① At pretreatment, absolute value of lymphocyte of 38 patients in all patients were low. There were 19 patients with lowered CD3 +, and 28 patients with lowered CD4 +/CD8 + ratio in 38 patients with T subset measured. ② The value of lymphocyte in plasma in patients after ICWM treatment increased from 1 00?10 9?0 46?10 9 L -1 to 1 92?10 9?0 74?10 9 L -1 ( P

Objective:To evaluate whether the decrease in peripheral blood monocyte count was a potential predictor for neutropenia in patients with nasopharyngeal carcinoma and cervical cancer.Methods:The medical records of 95 patients with nasopharyngeal carcinoma and cervical carcinoma who received intensity-modulated radiation therapy (IMRT) combined with paclitaxel liposomes and platinum (TP) synchronous chemotherapy and presented with neutropenia in the Second Affiliated Hospital of Soochow University from January 2017 to December 2018 were retrospectively analyzed. Paired sample t-test was used to assess whether the number of days when the monocytes initially dropped/decreased to lowest level/eventually increased to normal value was significantly less than those of the neutrophils. In addition, the chi-square test was performed to determine the correlation between the degree of reduction in the absolute neutrophil count (ANC) and baseline absolute monocyte count (AMC). Results:The change trend of AMC was consistent with that of ANC in the two cycles of concurrent chemotherapy. The number of days when AMC initially decreased/decreased to the lowest level/finally increased to normal value was significantly less than that of ANC (4 d vs. 6 d, 4 d vs. 10 d, P<0.001; 5 d vs. 6 d, 6 d vs. 9 d, 7 d vs. 12 d, P<0.001). However, no correlation was found between the baseline level of monocytes and the degree of subsequent neutropenia [(AMC<0.4×10 9) vs.( AMC≥0.4×10 9)=32 vs. 63, P=0.172]. Conclusions:Decreased monocyte count is an important potential predictor for neutropenia and a significant indicator for guiding the next monitoring of neutrophil count and treatment with granulocyte colony-stimulating factor.

Objective To investigate the effects of transarterial chemoembolization (TACE)treatment interval on the prognosis of patients with advanced hepatocellular caisinoma(HCC).Methods We retrospectively collected clinical data of 123 advanced HCC patients treated with repeated TACE.The patients were divided into two groups (group A with fixed repeated treatment interval and group B with that according to the clinical needs).Cox regression,survival curve and log-rank test were used to assess the effects of the treat-ment intervals on prognosis.Results The treatment intervals of the group A and group B were (1.1±0.3)months and (3.0±1.5) months,respectively (P <0.001).Multivariate Cox analysis showed the efficacy (P =0.024)and repetition periods (P <0.001 ) were independent prognostic factors.Conclusion TACE interval is independent risk factor for the prognosis of patients with ad-vanced HCC.Repeated TACE treatment according to clinical needs may be more favorable for prognosis of the patients.

[ ABSTRACT] AIM:To investigate the effect of DEK downregulation on the apoptosis of gastric carcinoma SGC-7901 cells, and to explore its associations with NF-κB signaling pathway and apoptosis related proteins.METHODS:SGC-7901 cells with different treatments were divided into 3 groups including untreated group, control siRNA group and DEK siRNA group.The expression of DEK at mRNA and protein levels in the SGC-7901 cells was detected by real-time PCR and Western blot.The cell apoptosis was examined by flow cytometry.Furthermore, the activities of caspase-3 and caspase-9 in the SGC-7901 cells were investigated by Caspase-Glo?-3/9 kit.Finally, the expression of key regulatory pro-tein p65 of NF-κB signaling pathway and apoptosis-related proteins Bcl-2 and Bax in the SGC-7901 cells was investigated by Western blot.RESULTS:Compared with untreated group and control siRNA group, the expression of DEK at mRNA and protein levels was significantly downregulated in DEK siRNA group (P<0.05).In addition, the ratios of early phase apoptosis and total apoptosis in DEK siRNA group were markedly higher than those in untreated group and control siRNA group (P<0.05).Most notably, the decrease in p65 and Bcl-2 proteins, increase in Bax protein and the increases of caspase-3 and caspase-9 activities were observed in DEK siRNA group.CONCLUSION:Downregulation of DEK mediates cell apoptosis of gastric carcinoma may be tightly associated with NF-κB signaling pathway.

Tepoxalin is a potent inhibitor of both the cyclooxygenase and lipoxygenase pathways of the arachidonic acid cascade, as well as a potent anti-inflammatory and control-pain (postoperation, arthritis et. al.) agent. The new method about the use of novel synthesis reagents and the first using ionic liquid as reactive solvent to synthesize tepoxalin were presented in this paper. The ionic liquid can be easily recycled and reused for several runs efficiently. The analgesic activity of tepoxalin was detected by acetic acid test on mice. The analysis of variance showed that oral administration of tepoxalin could significantly inhibit the number of writhing response within 1 hour and prolong the latent time in a dose dependent manner as compared with CMC control group (P < 0.05). At the same time, tepoxalin had the same analgesic activity as diclofenac sodium.

Objective To explore the effect of using cluster nursing measures on expectoration in mechanical ventilation patients after craniocerebral operation. Methods Convenient sampling and controlled trials at not the same period were used. Sixty-seven mechanical ventilation patients after craniocerebral operation were selected as the research objects in Department of Neurosurgery Intensive Care Unit (ICU) of the First Hospital Affiliated to Wenzhou Medical College. Thirty-two patients treated from June 2015 to June 2016 were assigned in the control group, and they were given routine respiratory nursing care; 35 patients admitted and treated from July 2006 to July 2017 were included in the intervention group, and they were given evidence-based cluster nursing intervention measures on the basis of routine care. The differences in expectoration effect, arterial blood gas analysis index, incidence of pulmonary infection and prognosis of patients in two groups were compared. Results Compared with control group, the amount of expectoration in the intervention group was significantly increased (mL/d: 49.69±9.45 vs. 33.72±10.63, P < 0.05), while the daily number of sputum suction (times: 21.57±2.31 vs. 28.76±22.66), the time needed for each sputum suction(s: 6.81±1.74 vs. 9.28±2.52), respiratory frequency (bpm: 26.26±1.83 vs. 28.58±1.36), incidence of pulmonary infection [0 vs. 12.5% (4/32)], time of mechanical ventilation (days: 6.37±2.51 vs. 8.92±3.32), time of ICU stay (days: 7.49±3.87 vs. 10.33±2.12), time of hospital stay (days: 10.31±1.99 vs. 14.56±3.57), fatality rate [8.6% (3/35) vs. 21.9% (7/32)] in the intervention group were significantly decreased (all P < 0.05); after treatment the arterial partial pressure of oxygen (PaO2) and pulse oxygen saturation degree (SpO2) were significantly increased than those before treatment, and the arterial partial pressure of carbon dioxide (PaCO2) was significantly decreased than that before treatment, and the degrees of improvement in the intervention group on 5 days were significantly better than those in the control group [PaO2(mmHg, 1 mmHg = 0.133 kPa): 60.89±3.44 vs. 57.34±2.49, PaCO2(mmHg): 41.06±4.32 vs. 45.22±4.78, SpO2: 0.986±0.030 vs. 0.963±0.023, all P < 0.05]. Conclusion The cluster nursing measures can effectively improve the expectoration effect for mechanical ventilation patients after craniocerebral surgery, reduce the mortality and incidence of pulmonary infection, shorten the stay in ICU and improve the prognosis, suggesting that the measures be worthy to be applied widely in clinics.

Objective:To construct and validate a theoretical model of residents′ willingness to participate in tiered medical care based on harmonious management theory, providing reference for promoting the tiered medical care system and aiding governmental decision-making.Methods:Based on the harmonious management theory and literature review, a model capturing residents′ propensity to engage in tiered medical care was formulated. Using convenience sampling method, a questionnaire survey was conducted on 2 067 residents from 24 communities in Zhejiang province from April to May 2022. Descriptive statistical analysis was conducted on the survey results, and multilevel linear regression and structural equation modeling were used to analyze the driving mechanism of residents′ willingness to participate in tiered medical care.Results:The willingness rate of residents to participate in tiered medical care was 69.7%, which was at an average level. Regression insights highlighted the positive influence of policy support perception ( β=0.170, P<0.01), awareness of management mechanisms ( β=0.093, P<0.01), cognitive attitudes ( β=0.102, P<0.01), and trust levels ( β=0.244, P<0.01) on residents′ participation willingness. In contrast, resource allocation perceptions lacked a significant effect ( β=0.065, P>0.05). The structural equation model revealed that cognitive attitudes played a mediating role in the " policy system perception → participation willingness" and " management mechanism perception → participation willingness" pathways, with effect sizes of 0.030 and 0.039, respectively. Trust levels also mediated these paths, with effect sizes of 0.039 and 0.045, and entirely mediated the " resource allocation perception → participation willingness" path, registering an effect size of 0.053. Conclusions:The harmonious management theory can be used to explain the formation mechanism of residents′ willingness to participate in tiered medical care. The government and medical institutions urgently need to further improve residents′ awareness of tiered medical care, focus on enhancing residents′ trust, and further improve policies and management measures such as financial investment, medical insurance reimbursement, and referral systems.
