Objective To study the relationships among resilience, self-awareness, personality, stress level and mental health in the warship soldiers. Methods Resilience Scale for Adults ( RSA), Eysenck Personality Questionnaire ( EPQ), Self Acceptance Questionnaire( SAQ), General Self-Efficacy Scale( GSES), Wallance Self Concept Scale (WSCS), Psychological Stress Self-evaluation Test (PSET) and Symptom Checklist (SCL-90)were used to survey 1451 warship soldiers. Results ① 2.5％ of the warship soldiers reported obvious psychological stress. Mental health of warship soldiers was worse than the norm of China population, except for obsessivecompulsive and interpersonal sensitivity factor. While the scores of other factors were significantly higher than the norm of Chinese soldiers(P＜0.01). ②The total scores of SCL-90, psychological stress and resilience, internal/external had negative correlation with self-awareness, and positive correlation with neuroticism. Compared to the SCL-90-negative group,SCL-90-positive soldiers (SCL-90 total score ＞ 160) had higher scores of nervousness and PSET and lower scores of RSA, internal/external and self-awareness (P ＜ 0.01 ). ③Regression analysis showed that stress levels, emotional stability,self-awareness and resilience were able to predict 35.1％ of mental health in warship soldiers. Mental health, emotional stability, internal/external and resilience were able to predict 33.2％of individual's stress level. Conclusion To some extent, warship soldiers have psychological stress and mental health problems. Resilience, personality, self-awareness are important factors affecting psychological stress and mental health.

OBJECTIVETo study the efficacy and safety of thoracoscopic and laparoscopic esophagectomy for esophageal carcinoma.

METHODSBased on hospitalization data from March 2011 to March 2014, 62 cases of esophageal carcinoma treated with thoracoscopic and laparoscopic esophagectomy (minimally invasive group, with 45 male patients) and other 62 cases treated with open esophagectomy (open esophagectomy group, with 45 male patients) were analyzed in a retrospective cohort. The mean age of two groups were (62±9) years and (62±8) years, respectively. Quantitative data were analyzed using t-test, whereas qualitative variables were tested with χ2 test. There were no significant difference in age, tumor location, pathological type, tumor staging between two groups (P>0.05). Perioperative data and three-year clinic outcome were collected. The three-year survival curve were calculated with the Kaplan-Meier method and compared by the log-rank test between the two groups.

RESULTSCompared with open esophagectomy group, minimally invasive group has less amount of bleeding during operations ((231±40) ml vs. (302±37) ml, t=4.63, P=0.000), pleural drainage after operations ((490±41) ml vs. (1 090±43) ml, t=-79.59, P=0.000), and postoperative hospital stay ((16±4) days vs. (17±4) days, t=-2.61, P=0.010). Meanwhile, minimally invasive group has more operation time ((272±39) minutes vs. (242±45) minutes, t=3.97, P=0.000) and total and thoracic cavity retrieved lymph nodes (30±5 vs. 28±4, t=2.39, P=0.018; 15±4 vs. 14±3, t=2.59, P=0.011). Nineteen and 31 patients had postoperative complications and statistical significance difference was found between two groups (χ2=4.83, P=0.028). The three-year survival rate was 73.2% in minimally invasive group and 71.4% in open esophagectomy group. There was no significance difference between two groups (χ2=0.170, P>0.05).

CONCLUSIONThoracoscopic and laparoscopic esophagectomy had the advantages of amount of bleeding, postoperative hospital stay and complications, and had the same three-year survival rate with open esophagectomy.

According to the taste analysis of Pudilan Xiaoyan Oral Liquid, the unpleasant taste of the oral liquid is mainly caused by the inherent taste of Chinese medicine and the taste introduced in the preparation process, which leads to its unpopularity among children. Therefore, aiming at the special children patient group, Xiaoer Pudilan Xiaoyan Syrup was developed via technology optimization and dosage form improvement to improve the unpleasant taste and enhance the medication compliance among children. Based on the material properties of Pudilan Xiaoyan Oral Liquid and Xiaoer Pudilan Xiaoyan Syrup extracts, the authors compared the properties(pH, density, turbidity, viscosity, chromaticity, particle size), taste, content of five quality markers and in vivo pharmacokinetic characteristics of these two preparations, to evaluate the suitability of Xiaoer Pudilan Xiaoyan Syrup. The results showed that compared with those of Pudilan Xiaoyan Oral Liquid, the pH, density, turbidity, viscosity and chromaticity of Xiaoer Pudilan Xiaoyan Syrup were significantly changed, and the unpleasant taste was reduced by 26%; the transfer rate of the main active ingredients chicoric acid was increased, while the transfer rate of baicalin had small difference from that of the oral liquid. In addition, pharmacokinetics revealed that the total absorption amount of baicalin in vivo was higher, and the time to peak T_(max) of baicalin and oroxindin in the syrup and the mean residence time MRT_(last )of corynoline in vivo were significantly prolonged. The absorption degree of Xiaoer Pudilan Xiaoyan Syrup and Pudilan Xiaoyan Oral Liquid in the body was the same: baicalin>oroxindin>corynoline. The new dosage form process was simpler than that of the original dosage form, safe, environmentally friendly, reasonable and feasible, meeting the mass production demand. This provided a basis for the reasonable and scientific optimization of Xiaoer Pudilan Xiaoyan Syrup, and also laid a foundation for its further safe and rational use, so as to expand the clinical application in children.

There are many kinds of pharmaceutical preparations for children in China, which are generally divided into oral solid preparations and oral liquid preparations. Solid preparations, such as microtablets, pellets, dispersible tablets, and fine granules, have become the development trend of pediatric drugs. Liquid preparations mainly include syrup, suspension, oral solution, and drops. The poor taste and the treatment of drugs in children of different ages are the key factors affecting the efficacy, safety, and compliance of pediatric drugs. To reduce the risk caused by the fluctuation of blood concentration and improve the oral compliance of pediatric drugs, it is urgent to develop new techniques for granulation and flavor maskingto improve the poor taste of solid preparations. For liquid pre-parations with poor taste, the flavor correction technique should be used. This paper summarized the new pharmaceutical techniques for granulation and flavor masking, and it was found that sustained/controlled-releasegranules, fine granules, and chewing solid mini-tablets became the mainstream of oral solid preparations for children. Generally, multiparticle preparation, coating, microencapsulation, and other granulating techniques were involved in these preparations. Granulation and flavor masking are closely related and synergetic. Flavor masking techniques mask the bitter taste of Chinese medicine from four aspects, including confusing the brain taste, changing the compounds, reducing the exposure of bitter molecules to bitter receptors in the mouth, and numbing the taste cells to increase the threshold of bitter perception. At present, the main drugs for children on the market mainly inhibit the oral release of bitter drugs.

To clarify the metabolic transformation mechanism of phenylethanoid glycosides in Xiaoer Chiqiao Qingre Granules in vivo, this study extracted and separated the phenylethanoid glycosides in Xiaoer Chiqiao Qingre Granules. Based on UPLC-Q-TOF-MS/MS technology, the retention time and primary and secondary mass spectrometry information were analyzed by UNIFI software, and 11 phenylethanoid glycosides in Xiaoer Chiqiao Qingre Granules were preliminarily identified. Sixty-nine metabolites related to phenylethanoid glycosides were identified from the plasma samples of juvenile rats after administration of Xiaoer Chiqiao Qingre Granules. In addition, this study simulated the transformation system of intestinal flora in children, and discussed the metabolic effects of intestinal flora on the representative components forsythoside A, forsythoside E, and salidroside of phenylethanoid glycosides. The model of gastrointestinal heat retention in children with food accumulation was established to study the differential metabolites of phenylethanoid glycosides. Through the comparative analysis of the representative components absorbed in blood and the intestinal floral transformation products, it was found that the main metabolic pathways of phenylethanoid glycosides were dehydrogenation, oxidation, acetylation, sulfation, and glucuronidation. The findings of this study revealed the transformation law of phenylethanoid glycosides in the gastrointestinal tract. Through the preliminary discussion of the pharmacological mechanism, this study provides references for further clarifying the pharmacodynamic material basis of Xiaoer Chiqiao Qingre Granules and exploring the pediatric Chinese medicine compound.

This study aimed to elucidate the digestive characteristics of flavonoid components in Xiaoer Chiqiao Qingre Granules(XECQ) in the gastrointestinal environment of infants. An in vitro model was established to simulate the gastric and intestinal environment of infants. UPLC was used to analyze the content change of flavonoid components in XECQ, and their overall content was integrated through the mass fraction weight coefficient method. UPLC-Q-TOF-MS was employed to determine the digestive products of flavonoid components in gastrointestinal fluids and their metabolic pathways. The results showed that in the process of digestion, 11 digestion products were generated by oxidation, reduction, deglycosylation, methylation and other phase Ⅰ metabolism. From flavonoid content and component changes, it was found that the flavonoid components in XECQ were relatively stable in the gastric fluid, while their content in the intestinal fluid was first increased and then maintained stable. This was mainly because flavonoid components were released from proteins, polysaccharides and other macromolecular substances during gastrointestinal digestion. In addition, phase Ⅰ metabolism occurred, but with relatively low metabolic rate, resulting in their stable content. This study preliminarily explored the digestive characteristics of flavonoid components in XECQ in the infant gastrointestinal environment, which laid a foundation for further studying the absorption, transport and metabolism of pharmacodynamics components in XECQ, and facilitated the study of the biopharmaceutical pro-perties of pediatric Chinese medicine.

Objective: To analyze the impact of metabolic risk factors on the epidemiological characteristics of the reactivation of inactive HBsAg carriers (IHC) and provide effective intervention measures to standardize the management of chronic hepatitis B infections. Methods: Based on the chronic hepatitis B infection cohort established in 2010 in Jiangsu province, six follow-up visits from 2012 to 2020 were conducted to analyze the characteristics and influencing factors of the hepatitis B reactivation of IHC and the impact of metabolic risk factors, including obesity, high blood pressure, diabetes and hyperglycemia. Results: From 2012 to 2020, 2 527 IHC and 17 730 person-years were observed during a median follow-up period of 7.0 person-years. Ninety-eight cases of hepatitis B reactivation, with a cumulative reaction rate, was 3.9%, and the incidence density was 5.53/1 000 person-years. Multivariate Cox proportional risk regression analysis showed that age and baseline HBV DNA were independent risk factors of HBV reactivation. Compared with the patients ≥60 years, 40-49 age group (aHR=2.16, 95%CI:1.20-3.90) and 20-29 age group (aHR=5.48, 95%CI:2.07-14.48) were significantly associated with hepatitis B reactivation. Compared with the HBV DNA negative patients at baseline, the risk of hepatitis B reactivation was higher in the group with low HBV DNA level 100-1 999 IU/ml (aHR=1.67, 95%CI:1.11-2.52). Stratification analysis results showed that compared with those without metabolic risk factors, in the ≥50 age group, patients with ≥2 metabolic risk factors showed adjusted HR of 2.73 (95%CI:1.08-6.96). Conclusions: The risk of hepatitis B being reactive is the persistent existence of IHC in communities in Jiangsu province, especially young adults, low-level HBV DNA carriers, and IHC with ≥2 metabolic risk factors. Follow-up for these IHC should be strengthened to reduce the risk of disease progression by antiviral treatment at the right time.
