Objective To explore the current status of H.pylori infection in the natural population of Sanya City,analyze its influencing factors,and provide a reference basis for the prevention and control of H.pylori infection.Methods A total of 677 residents from four districts of Sanya City were selected by overall stratified random sampling method,and were subjected to urea 14C breath test and questionnaire survey to calculate the positive rate of H.pylori in the natural population and analyze the influencing factors of H.pylori infection.Results A total of 606 residents were included,and the number of H.pylori positive detections was 261,with a positive detection rate of 38.5％.Among them,different ethnicity,marital status,smoking,eating vegetables and fruits,and literacy level were associated with H.pylori infection(P＜0.05);gender,age,BMI,alcohol consumption,drinking water source,betel quid chewing,and the number of cohabitants were not significantly associated with H.pylori infection(P＞0.05).Family infection was an independent risk factor for H.pylori infection in the natural population of Sanya City,and Li ethnicity,frequent consumption of fruits and vegetables,and college and higher education level were independent protective factors for H.pylori infection in the natural population of Sanya City.Conclusion The rate of H.pylori infection in the natural population of Sanya City is lower than the national average.Consuming more fruits and vegetables and improving the awareness of hygiene protection are conducive to the prevention of H.pylori infection;and the promotion of the family and related members with the same examination and treatment is important to avoid aggregation of infection within the family.

Patients with severe trauma require an extremely timely treatment and transfusion plays an irreplaceable role in the emergency treatment of such patients. An increasing number of evidence-based medicinal evidences and clinical practices suggest that patients with severe traumatic bleeding benefit from early transfusion of low-titer group O whole blood or hemostatic resuscitation with red blood cells, plasma and platelet of a balanced ratio. However, the current domestic mode of blood supply cannot fully meet the requirements of timely and effective blood transfusion for emergency treatment of patients with severe trauma in clinical practice. In order to solve the key problems in blood supply and blood transfusion strategies for emergency treatment of severe trauma, Branch of Clinical Transfusion Medicine of Chinese Medical Association, Group for Trauma Emergency Care and Multiple Injuries of Trauma Branch of Chinese Medical Association, Young Scholar Group of Disaster Medicine Branch of Chinese Medical Association organized domestic experts of blood transfusion medicine and trauma treatment to jointly formulate Chinese expert consensus on blood support mode and blood transfusion strategies for emergency treatment of severe trauma patients ( version 2024). Based on the evidence-based medical evidence and Delphi method of expert consultation and voting, 10 recommendations were put forward from two aspects of blood support mode and transfusion strategies, aiming to provide a reference for transfusion resuscitation in the emergency treatment of severe trauma and further improve the success rate of treatment of patients with severe trauma.

Artemisia argyi is a perennial herbaceous herb of the Artemisia family, with leaves for medical use. However, the germplasm of A. argyi is seriously unclear and mixed during production, and it is urgent to protect new varieties of A. argyi. The distinctness, uniformity, and stability(DUS) testing of the new varieties of plants is the basis for the protection of new varieties of plants, and the development of the DUS testing guidelines is the technical basis for DUS testing. To develop the DUS testing guidelines of A. argyi, A. argyi of 100 germplasm was used as the research objects, and their agronomic and medicinal quality characters were observed and measured during six growth stages, and each character was graded and described. A total of 53 test characters were determined, including 19 characters that must be tested; there were four plant characters, two rhizome characters, five stem characters, three branching characters, 29 leaf characters, three floral characters, five medicinal quality characters, and two other characters. It also involved 16 quality characters, 22 quantitative characters, and 15 pseudo-quantitative characters. Seven grouping characters were determined from 53 characters, including "emergence period" "plant-plant type" "branching-primary branching site" "stem-color" "middle leaf-number of leaf splits" "budding period", and "plant-height". By searching for standard characters, 16 standard varieties were ultimately determined. The preparation of this guideline was of great significance for the review and protection of new A. argyi varieties, the protection of breeders' rights, and the promotion of the development of A. argyi industry.

To clarify the content characteristics of mineral elements in different Artemisia argyi germplasm resources and their relationship with the quality properties of Artemisiae Argyi Folium, this study measured the content of 10 mineral elements including nitrogen(N), phosphorus(P), potassium(K), calcium(Ca), magnesium(Mg), aluminum(Al), manganese(Mn), iron(Fe), copper(Cu), and zinc(Zn) in 100 Artemisia argyi germplasm samples. Besides, their relationship with the quality properties of Artemisiae Argyi Folium was explored by correlation analysis, path analysis, and cluster analysis. The results demonstrated that the variation coefficient of the 10 mineral elements in Artemisiae Argyi Folium ranged from 12.23% to 64.38%, and the genetic diversity index from 0.97 to 3.09. The genetic diversities of N, P, and Zn were obvious. As revealed by the correlation analysis, N, P, and K showed strong positive correlations with each other. Except that Mg and Al were negatively correlated, Ca, Mg, Al, Mn, Fe, Cu, and Zn were positively correlated. The correlation analysis of mineral elements with the quality properties of Artemisiae Argyi Folium proved the significant correlations of 17 pairs of characters. According to the path analysis, P, K, Ca, and Mn greatly affected the yield of Artemisiae Argyi Folium, P, K, and Mg the output rate of moxa, N, P, and K the content of total volatile oil, P and K the content of eucalyptol, and P, K, and Ca the content of eupatilin. The 100 germplasm samples were clustered into three groups. Specifically, in cluster Ⅰ, the enrichment capacity of P, K, and Mg elements was strong, and the comprehensive properties of mineral elements were better, implying good development potential. Ca, Mn, Fe, and Zn elements in cluster Ⅱ and N and Al in cluster Ⅲ displayed strong enrichment capacities. This study has provided new ideas for resource evaluation and variety breeding of A. argyi and also reference for fertilizer application.

Objective: To estimate stomach cancer incidence and mortality in Henan, 2016 and analyze the trend of stomach cancer incidence and mortality from 2010 to 2016. Methods: Stomach cancer related data in 2016 was extracted from Henan cancer registration and follow-up system. All data were qualified in validity, reliability and completeness according to the Guideline on Cancer Registration in China and International Agency for Research on Cancer (IARC/IACR). The incidence and mortality of stomach cancer were estimated by areas, gender and age based on the quality data and the registered population data of Henan province in 2016. The epidemic trend of stomach cancer was also been evaluated based on the age-standardized incidence and mortality by Chinese population (ASR China) from 2010 to 2016. Results: In 2016, the estimated incident cases of stomach cancer were 44 311. The incidence was 41.07/100 000, ASR China was 30.17/100 000, ASR by world population (ASR world) was 30.36/100 000, and the cumulative incidence rate was 3.84%. The incidences of male and female were 55.65/100 000 and 25.35/100 000, respectively. Meanwhile, 32 927 people died of stomach cancer in Henan. The mortality was 30.52/100 000, ASR China was 21.45/100 000, ASR world was 21.54/100 000, and the cumulative mortality was 2.53%. From 2010 to 2016, both the ASR China for incidence and mortality of stomach cancer in Henan showed a steady downward trend. In rural, the ASR China for incidence and mortality decreased rapidly, while the stable trend was observed in urban. Nevertheless, the incidence and mortality of stomach cancer in rural were still higher than those in urban. Conclusions: The incidence and mortality of stomach cancer in Henan province showed steadily declining trend from 2010 to 2016, and the geographical distribution difference between rural and urban areas was gradually narrowing. However, the disease burden was still high in 2016.

Objective: To investigate the effectiveness of nucleos(t)ide analogues in the treatment of HBeAg-positive chronic hepatitis B with normal alanine aminotransferase and high level of HBV DNA. Methods: Treatment-naïve chronic hepatitis B patients who were followed up at the Center of Infectious Diseases, West China Hospital of Sichuan University from January 2019 to January 2020 were selected as subjects. Demographic characteristics, the results of laboratory examination before treatment and one year after treatment were retrospectively collected. Patients were divided into tenofovir dipivoxil (TDF) and propofol fumurate tenofovir (TAF) treatment group according to different types of medication. The changes of serum HBV DNA level, HBeAg serological conversion and HBsAg quantitative level were analyzed and compared between the two groups. Results: A total of 38 cases were enrolled. Among them, there were 16 and 22 cases in the TDF and TAF group, respectively. There was no statistically significant difference in demographic characteristics, baseline HBV DNA levels and HBsAg quantitative levels between the two groups. Virological response was achieved in 60.5% (23/38) of patients after one year of antiviral therapy. Serum HBV DNA levels below the lower limit of detection [68.2% (15/22) vs. 50.0% (8/16), P=0.258] and higher HBeAg seroconversion rate [18.2%] (4/22) vs. 6.3% (1/16), P=0.374] was obtained in TAF than TDF group; however, there was no statistically significant differences between the two. Serum HBsAg quantitative level was significantly reduced with TDF and TAF treatment. In addition, alanine aminotransferase elevation was reduced in TAF than TDF treated group. Multivariate logistic regression analysis showed that patient age was an independent predictor of a virological response to antiviral therapy. Conclusion: HBeAg-positive CHB patients with normal alanine aminotransferase, and high HBV DNA level can obtain better curative effect after TDF and TAF treatment.

Objective: To explore the clinical application value of two longitudes three transverses method in the location of the perforator of thoracodorsal artery perforator and deep wound repair. Methods: The retrospectively observational study was conducted. From December 2018 to June 2020, 17 patients with deep wounds who were admitted to the Affiliated Hospital of Zunyi Medical University met the inclusion criteria and were included in this study, including 7 males and 10 females, aged 12 to 72 years. The wound areas of patients after debridement were 7 cm×3 cm to 11 cm×7 cm. Two longitudinal lines were located through the midpoint of the armpit, the posterior superior iliac spine, and the protruding point of the sacroiliac joint, and three transverse lines were located 5, 10, and 15 cm below the midpoint of the armpit between the two longitudinal lines, i.e. two longitudes three transverses method, resulting in two trapezoidal areas. And then the thoracodorsal artery perforators in two trapezoidal areas were explored by the portable Doppler blood flow detector. On this account, a single or lobulated free thoracodorsal artery perforator flap or flap that carrying partial latissimus dorsi muscle, with an area of 7 cm×4 cm to 12 cm×8 cm was designed and harvested to repair the wound. The donor sites were all closed by suturing directly. The number and location of thoracodorsal artery perforators, and the distance from the position where the first perforator (the perforator closest to the axillary apex) exits the muscle to the lateral border of the latissimus dorsi in preoperative localization and intraoperative exploration, the diameter of thoracodorsal artery perforator measured during operation, and the flap types were recorded. The survivals of flaps and appearances of donor sites were followed up. Results: The number and location of thoracodorsal artery perforators located before operation in each patient were consistent with the results of intraoperative exploration. A total of 42 perforators were found in two trapezoidal areas, with 2 or 3 perforators each patient. The perforators were all located in two trapezoid areas, and a stable perforator (the first perforator) was located and detected in the first trapezoidal area. There were averagely 1.47 perforators in the second trapezoidal area. The position where the first perforator exits the muscle was 2.1-3.1 cm away from the lateral border of the latissimus dorsi. The diameters of thoracodorsal artery perforators were 0.4-0.6 mm. In this group, 12 cases were repaired with single thoracodorsal artery perforator flap, 3 cases with lobulated thoracodorsal artery perforator flap, and 2 cases with thoracodorsal artery perforator flap carrying partial latissimus dorsi muscle. The patients were followed up for 6 to 16 months. All the 17 flaps survived with good elasticity, blood circulation, and soft texture. Only linear scar was left in the donor area. Conclusions: The two longitudes three transverses method is helpful to locate the perforator of thoracodorsal artery perforator flap. The method is simple and reliable. The thoracodorsal artery perforator flap designed and harvested based on this method has good clinical effects in repairing deep wound, with minimal donor site damage.

Aim To investigate the possible mechanism of paeonol inhibiting the inflammatory response of fibroblast synovial cells (RA-FLSS) in rheumatoid arthritis. Methods CCK-8 assay was used to detect Paeonol's inhibitory level on the abnormal proliferation of arthritis human fibroblast synovial cells (RA-FLSs). The levels of endoplasmic reticulum stress-related proteins MANF and ATF6 were detected by Western blot. Cell localization of transcription factor p65 and Mesencephalic Astrocyte Derived Neurotrophic Factor (MANF) was detected by immunofluorescence. RT-qPCR detected the changes of p65 target genes. Results Paeonol could significantly inhibit the abnormal proliferation of RA-FLSS cells. Paeonol activates ATF6 and increases the expression of MANF. Paeonol promoted the nuclear transfer of MANF protein and inhibited the transcriptional activity of p65. Conclusion Paeonol promotes the expression of MANF and nuclear transfer through the endoplasmic reticulum stress pathway and affects the progression of RA by inhibiting the transcriptional activity of p65.

Objective To investigate the effects of hot spring baths on blood pressure, resting heart rate, cardiovascular function related indicators and physical signs in population with high-normal blood pressure. Methods Residents of typical hot spring areas in Guizhou Province were included as the subjects. According to the epidemiological survey of the research group and the physical examination results before the intervention, combined with the inclusion and exclusion criteria, a total of 217 people with high normal blood pressure were selected as the observation subjects. The intervention of hot spring baths was carried out for four weeks, once time per day, 5 times per week, for 40-50 minutes each time. After the intervention, the blood pressure, resting heart rate and serum levels of creatine kinase(CK), lactate dehydrogenase(LDH), and α-hydroxybutyrate dehydrogenase(α-HBDH)were detected, and the improvement of cardiovascular related signs(palpitation, dizziness/headache, cough/sputum and night sweats)were clinically examined. SPSS 23.0 software was used for statistical analysis. Results Paired t-test results showed that the systolic blood pressure, diastolic blood pressure and resting heart rate of 217 high normal blood pressure subjects were significantly lower after hot spring baths(P < 0.01). Further analysis revealed that the number of people with high normal blood pressure dropped from 217 to 128 after the hot spring baths. Before the intervention, 95 of the 217 people with high-normal blood pressure had resting heart rates between 80 and 90 beats/min, and 35 of them above 90 beats/min. After the intervention, the resting heart rates of those above people decreased to 68 and 14, respectively. Serum levels of cardiovascular related indicators showed that CK, LDH, and α-HBDH levels in people with high-normal blood pressure decreased to some extent after the intervention, and CK level was significantly lower than that before the intervention(P < 0.05). The results of clinical examination showed that hot spring baths had a significant improvement effect on palpitation, dizziness/headache, cough/expectoration, and night sweats in people with high-normal blood pressure. Conclusion The typical hot spring baths in Guizhou Province can reduce the blood pressure and resting heart rate in population with high-normal blood pressure, and improve the cardiovascular function related indicators and physical signs to a certain extent.
