OBJECTIVE:To optimize water reflux extraction technology of Jiuwei yiwei mixture. METHODS:With the over-all score of the content of salvianoli acid B,a water-soluble component of the principal drug Salvia miltiorrhiza,the content of pae-oniflorin in Paeonia Radix Rubra and dry ointment yield rate as the observed index,and taking soaking time,extraction time, amount of water added,and extraction times as the factors,L9(34)orthogonal test was designed to optimize the extraction technolo-gy of Jiuwei yiwei mixture. And the verification test was conducted. RESULTS:The optimal technology was to add water with an amount 8 times as much as that of the drugs to soak them for 1 h and to conduct extraction twice,1 h for each. The overall scores of 3 batches of samples in the verification test were respectively 98.793,99.078 and 99.220(RSD<2%,n=3). CONCLUSIONS:The optimal technology for Jiuwei yiwei mixture is stable and feasible.

Objective:To evaluate the value of intraoperative magnetic resonance imaging (iMRI) combined with neuronavigation for the resection of insular gliomas.Methods:From August 2014 to October 2017 in the First Hospital Affiliated to Sun Yat-sen University,clinical data of 41 patients with insular glioma,who underwent the surgery assisted with 3.0T iMRI and neuronavigation,were analyzed retrospectively,and the resection extent,complications and prognosis were evaluated.Results:Subtotal tumor resection was achieved in 21 patients and partial resection was done in 20 after iMRI scanning.After further resection,total tumor resection was achieved in 16 patients,subtotal resection in 18 and partial resection in 7.There was a statistical significant difference in tumor resection between pre-iMRI and post-iMRI according to the Fisher test (P<0.05).In the follow-up from 3 months to 3 years,the symptoms of the 41 patients had improved.Conclusion:iMRI corrected the shift of brain.Neuronavigation can accurately and timely assess the degree of resecting tumor.The combination of neuronavigation with surgery can maximally and safely resect insular glioma.

ObjectiveTo investigate whether anti-PD-1 monoclonal antibody can improve the efficacy and safety of cryoablation combined with lenvatinib in the treatment of unresectable hepatocellular carcinoma (HCC). MethodsA retrospective analysis was performed for 232 patients with unresectable HCC who were treated at The Fifth Medical Center of Chinese PLA General Hospital from January 2018 to December 2022, among whom 128 received cryoablation combined with lenvatinib (double combination) and 104 received cryoablation combined with lenvatinib and anti-PD-1 monoclonal antibody (triple combination). Propensity score matching was performed at a ratio of 1∶1, and finally there were 86 patients in each group. The two groups were evaluated in terms of objective response rate (ORR), disease control rate (DCR), overall survival (OS), progression-free survival (PFS), and adverse events (AEs). The independent-samples t test was used for comparison of normally distributed continuous data between two groups, and the Mann-Whitney U test was used for comparison of non-normally distributed continuous data between two groups; the chi-square test was used for comparison of categorical data between two groups. Survival curves were plotted, and the Kaplan-Meier method was used to calculate the survival rate of patients in both groups, while the log-rank test was used for comparison between the two groups. The Cox regression model was used to calculate hazard ratio (HR) and 95% confidence interval (CI) and perform the univariate and multivariate analyses of influencing factors for prognosis. ResultsThe median follow-up time was 28 months, and there were 33 deaths (38.0%) in the triple combination group and 40 deaths (46.0%) in the double combination group. Compared with the double combination group, the triple combination group had significantly higher ORR (35.6% vs 14.5%, P=0.008) and DCR (86.1% vs 64.1%, P=0.003). OS and PFS in the triple combination group were significantly higher than those in the double combination group (P=0.045 and 0.026). The univariate and multivariate Cox proportional-hazards regression model analyses showed that treatment regimen (HR=0.60, P=0.038) and alpha-fetoprotein level (HR=2.37, P=0.001) were independent risk factors for OS, and treatment regimen (HR=0.65, P=0.025), diabetes mellitus (HR=1.94, P=0.005), whether or not to have received local treatment (HR=0.63, P=0.014), and distant metastasis (HR=0.58, P=0.009) were independent risk factors for PFS. There was no significant difference in the incidence rate of AEs between the two groups (P>0.05). ConclusionFor patients with unresectable HCC, the triple combination of cryoablation, lenvatinib, and anti-PD-1 monoclonal antibody significantly improves the treatment outcome and survival of patients compared with the double combination of cryoablation and lenvatinib, without increasing AEs, which provides a clinical basis for optimizing the treatment regimen for unresectable HCC.

BACKGROUND:
The 2019 novel coronavirus disease (COVID-19) has had a massive impact on public health, resulting in sudden dietary and behavioral habit changes. Frontline epidemic prevention workers play a pivotal role against COVID-19. They must face high-risk infection conditions, insufficient anti-epidemic material supplies, mental pressure, and so on. COVID-19 seriously affects their dietary and behavioral habits, and poor habits make them more susceptible to COVID-19. However, their baseline dietary and behavioral habits before COVID-19 and their willingness to change these habits after the outbreak of COVID-19 remain unclear for these workers in China. This study aimed to explore the baseline dietary and behavioral habits of frontline workers and their willingness to change these habits after the outbreak of the epidemic; in addition, susceptible subgroups were identified by stratified analyses as targets of protective measures to keep them from being infected with COVID-19.
METHODS:
A cross-sectional study was conducted through an online questionnaire using a sample of 22,459 valid individuals living in China, including 9402 frontline epidemic prevention workers.
RESULTS:
Before COVID-19, 23.9% of the frontline epidemic prevention workers reported a high-salt diet, 46.9% of them reported a high frequency of fried foods intake, and 50.9% of them smoked cigarettes. After the outbreak of COVID-19, 34.6% of them expressed a willingness to reduce salt intake, and 43.7% of them wanted to reduce the frequency of pickled vegetables intake. A total of 37.9% of them expressed a willingness to decrease or quit smoking, and 44.5% of them wanted to increase sleep duration. Significant differences in the baseline dietary and behavioral habits and the willingness to change their habits were observed between frontline epidemic prevention workers and other participants. Among the frontline epidemic prevention workers with poor dietary and behavioral habits before COVID-19, frontline epidemic prevention experience was a promoting factor for adopting worse dietary and behavioral habits, including those in the high-salt intake subgroup (OR, 2.824; 95% CI, 2.341-3.405) and the 11-20 cigarettes/day subgroup (OR, 2.067; 95% CI, 1.359-3.143).
CONCLUSIONS
The dietary and behavioral habits of frontline epidemic prevention workers were worse than that those of other participants before COVID-19. They had a greater willingness to adopt healthy dietary and behavioral habits after experiencing the outbreak of COVID-19. However, frontline epidemic prevention workers with poor dietary and behavioral habits before COVID-19 continued in engage in these poor habits. Dietary and behavioral intervention policies should be drafted to protect their health, especially frontline epidemic prevention workers with poor habits at baseline.
