OBJECTIVE: To compared the effect of different drying methods on drying characteristics, water effective diffusion coefficient and biased activation energy of Codonopsis Radix and to definite 3 different drying methods of varying temperature(45-55-60, 60-55-45, 60-45-60℃) and 3 constant temperature(45, 55, 60℃) on drying characteristic curves of different commercial grades of Codonopsis Radix. METHODS: Used R2, χ2 and RMSE as evaluation indexes, 10 typical drying kinetic models were selected to fit the drying curve of Codonopsis Radix, and the effective moisture diffusion coefficient and biased activation energy under different drying method were calculated. RESULTS: It was found that the Midilli model could well describe the drying process of different commercial grades of Codonopsis Radix, the water ratio of Codonopsis Radix showed an exponential downward trend. If the initial drying temperature was set above 55℃, the maximum drying rate could be reached within 2 h. And commercial grades temperature had certain influence on the effective water diffusion coefficient of Codonopsis Radix. Under the same temperature condition, the average speed of moisture migration during drying of Codonopsis Radix was:first-class> second-class>third-class, and the Deffwere 10.433 9×10-8, 5.545 2×10-8, 2.249 6×10-8·m2·s, respectively. The calculated bias activation energy of Codonopsis Radix was 2.943×104-4.378×104 J·mol-1, the order of bias activation energy of different drying methods was as follows:60-55-45℃ variable temperature<60-45-60℃ variable temperature<45-55-60℃ variable temperature<55℃ constant temperature<60℃ constant temperature <45℃ constant temperature, which indicated that the moisture in the medicinal materials was more likely to evaporate and overflow and consumes less energy than the constant temperature drying. In particular, the bias activation energy of 60-55-45℃ drying method was 77.54% and 81.86% of the other 2 variable temperature drying methods, which were 67.22%, 75.13% and 74.26% of the 3 kinds of constant temperature drying. CONCLUSION The use of cooling mode in the drying process can save more time and energy, and can provide experimental basis for the improvement of drying technology and optimization of drying process of Codonopsis Radix.

Objective:To evaluate the postoperative symmetry of soft and hard tissues in patients with unilateral old zygomatic fractures.Methods:A retrospective analysis of patients who underwent computer-assisted open reduction and internal fixation for unilateral old zygomatic complex fractures. The spiral CT data of the patient before and 1 year after operation was imported into ProPlan CMF 3.0 software to segment the skin and bone STL models. Eleven sets of soft tissue landmarks and 10 sets of hard tissue landmarks in the middle of the face were marked, with a coordinated system for measurement established. The asymmetry index (AI) between each mark point was calculated. The data were expressed by Mean±SD. Paired t-test was used to compare whether there was a statistical difference in the AI of each landmark before and after operation. P<0.05 was considered the difference to be statistically significant. At the same time, the study subjects were selected from the Chinese craniomaxillofacial three-dimensional morphological database. Microsoft Excel 2017 software was used to draw the AI baseline data map of common people. The patients’ soft and hard tissue landmarks AI (before and 1 year after surgery) were included in the AI baseline map of common people, and the patient’s soft and hard tissue symmetry was evaluated. Results:A total of 30 patients were included in the study, including 17 males and 13 females, age range from 18 to 55 years old, with an average age of 25.2 years. The preoperative hard tissue AI was 4.5±4.1, and the hard tissue AI was 2.0±1.7 one year after surgery, and the difference in the AI of each hard tissue landmark before and 1 year after operation was statistically significant( P<0.01 or <0.05). The preoperative soft tissue AI was 4.5±4.0, and the soft tissue AI was 2.3±1.9 one year after surgery, and the difference in the AI of each soft tissue landmark before and 1 year after operation was statistically significant( P<0.01 or <0.05). 50 common people were selected from the total database, including 25 men and 25 women, aged from 18 to 57 years old, with an average of 23.8 years old. The hard tissue landmark AI was 2.1±2.0, and the soft tissue landmark AI was 2.0±1.9. The hard tissue landmarks AI of patients 1 year after operation were all within the symmetrical baseline value, with good symmetry. The AI values of some soft tissue landmarks were higher than the symmetrical baseline value, indicating poor symmetry. Conclusion:The three-dimensional symmetry of the soft and hard tissues of patients with unilateral old zygomatic complex fractures after surgery was significantly improved compared with that before surgery. Compared with the normal range of the database, the postoperative hard tissue has better symmetry, but the postoperative soft tissue has poor symmetry.

BackgroundThe mental health level of the prison police is relatively low， so finding innovative ways to improve the mental health of them is of great significance for the safety of prison supervision and the implementation of peaceful China initiative. ObjectiveTo explore the relationship between perceived social support， perceived stress and psychological resilience with mental health of prison police， and to provide references for improving their mental health. MethodsIn March 2022， 424 policemen working in a male prison in a western province were selected by cluster sampling method， and investigated with the Perceived Social Support Scale （PSSS）， Chinese Perceived Stress Scale （CPSS）， Connor-Davidson Resilience Scale （CD-RISC） and General Health Questionnaire 20 （GHQ-20）， then Process 4.2 was used employed to verify the mediating role of perceived stress as well as the moderating role of psychological resilience in the relationship between perceived social support and mental health. Results①Male subjects scored higher on GHQ-20 than female subjects （t=2.095， P<0.05）. ②CPSS score was negatively correlated with PSSS and GHQ-20 scores （r=-0.670， -0.703， P<0.01）， and GHQ-20 score showed a positive correlation with PSSS and CD-RISC scores （r=0.580， 0.693， P<0.01）. ③Perceived social support positively predict mental health （β=0.154， 95% CI： 0.133~0.175， P<0.01）. ④Perceived stress played a mediating role in the relationship between perceived social support and mental health， and the mediation effect size was 0.087， accounting for 88.78% of the total effect （95% CI： 0.064~0.112， P<0.01）. ⑤Psychological resilience played a moderating role in the second half （perceived stress→mental health） of the mediating path of "perceived social support→perceived stress→mental health"（β=0.074， 95% CI： 0.046~0.102， P<0.01）. ⑥Psychological resilience also regulated the mediation effect of perceived stress on the relationship between perceived social support and mental health ［three regression coefficients tested in turn are significant： a=-0.537 （95% CI： -0.594~-0.480， P<0.01）， b1=-0.162 （95% CI： -0.197~-0.127， P<0.01）， b3=0.074 （95% CI： 0.046~0.102， P<0.01）］. ConclusionPerceived social support of prison police has an impact on their mental health both directly and indirectly through perceived stress. In addition， perceived social support of prison police has a moderated mediation effect on mental health， and it is partially moderated by psychological resilience.［ Funded by General Project of Sichuan Prison Administrative Bureau in 2022］

【Objective】 To investigate the management of adverse reactions to blood donation(ARBD) in blood services, so as to promote the surveillance of ARBD and improve the quality of blood donation service in Chongqing. 【Methods】 A questionnaire, involving the staff and facilities in blood donation sites as well as the prevention and treatment, the record and report, the following up and data related to ARBD was developed by Chongqing Society of Blood Transfusion in February 2019, and was issued to 18 blood services(1 blood center and its sub-center, 6 central blood stations and 11 hospital blood banks) in the Chongqing via email. The questionnaire was filled in and submitted before March 31 by management personnel participating in the investigation, and the data was collected, collated, revised and analyzed by Excel 2011. 【Results】 A total 19 questionnaires were collected, with the valid rate at 100%(19/19). 78.95%(15/19) of the blood services met the requirements of medical personnel allocation(>6 medical staff) when the number of daily blood collection was more than 60, and 100%(19/19)met the requirements of medical personnel allocation(2 to 6 medical staff) when the number of daily blood collection was less than 60. 89.47%(17/19) of the blood services were equipped with epinephrine hydrochloride, and 84.21%(16/19) with dexamethasone(an anti-allergic drug). There were significant differences in the allocation of other types of drugs. 100.00%(19/19) of the blood services formulated prevention and treatment measures concerning ARBD. In 2019, the incidence of ARBD in Chongqing was reported to be 0.54%(1 958 / 359 871), with the highestas [1.35%(223/16 543)] in subcenters and the lowest [0.32%(179/56 299)] in central blood centers (P<0.05). There was statistical significances in the incidences of ARBD reported by different blood stations(P<0.05). 【Conclusion】 The monitoring and management of ARBD among blood services in Chongqing should be further standardized in terms of staffing allocation, emergency drugs allocation and reporting, so as to gradually realize regional homogenization and ensure blood safety.

Objective:To investigate the clinical efficacy of neoadjuvant chemotherapy for the resectable locally advanced adenocarcinoma at the gastroesophageal junction.Methods:A retrospective cohort study was conducted to analyze 86 patients with resectable locally advanced Siewert type Ⅱ and Ⅲ adenocarcinoma at the gastroesophageal junction (T 3-4N +M 0) who were admitted to the Panzhihua Central Hospital of Sichuan Province from January 2013 to January 2016. All the patients were divided into the neoadjuvant chemotherapy group [preoperative XELOX regimen (oxaliplatin + capecitabine) adjuvant chemotherapy + surgery + postoperative XELOX regimen adjuvant chemotherapy, 46 cases] and non-neoadjuvant chemotherapy group (surgery + postoperative XELOX regimen adjuvant chemotherapy, 40 cases) according to whether neoadjuvant chemotherapy was performed before surgery. The total gastrectomy + Roux-en-Y esophagojejunostomy + D 2 lymphadenectomy or proximal subtotal gastrectomy + esophageal gastric remnant anastomosis + D 2 lymphadenectomy were applied to patients by the same team of doctors. The observation indicators included treatment situations, results of postoperative pathological examination and prognosis in the two groups. Results:In the neoadjuvant chemotherapy group, 25 patients (54.3%) had partial remission (PR), 21 patients (45.7%) had stable disease (SD), the clinical response rate was 54.3% (25/46), tumor control rate was 100.0% (46/46), and clinical stage reduction rate was 37.0% (17/46). Compared with the non-neoadjuvant chemotherapy group, the neoadjuvant chemotherapy group had a higher R 0 resection rate [100.0% (46/46) vs. 80.0% (32/40), χ2 = 4.024, P = 0.045], and in the neoadjuvant chemotherapy group, the pathological complete remission [tumor regression grade (TRG) 0] rate was 13.0% (6/46), and the overall pathological response (TRG 1 + TRG 0) rate was 56.5% (26/46). The postoperative pathological examination showed that the neoadjuvant chemotherapy group and the non-neoadjuvant chemotherapy group had statistically significant differences in the longest tumor diameter, vessel carcinoma embolus, perineural invasion, and pathological TNM staging (all P < 0.05). However, there was no statistical difference in the total humber of lymph nodes, the number of positive lymph nodes, pathological T stage, N stage, and human epidermal growth factor receptor 2 (HER2) expression in specimens (all P > 0.05). In the neoadjuvant chemotherapy group, 6 patients had grade 3 adverse reactions, and chemotherapy was suspended or the dose was adjusted. Adverse reactions in the blood system included the red blood cells reduction, white blood cells reduction and thrombocytopenia. Other adverse reactions included nausea, vomiting, and decreased appetite. There were no deaths related to radiotherapy. In the neoadjuvant chemotherapy group, the median tumor-free survival time was 20 months (5-36 months), and the 1-year and 3-year tumor-free survival rates were 89.5% and 52.4%, respectively; the median postoperative overall survival time was 20 months (9-36 months), and the 1-year and 3-year overall survival rates were 91.0% and 48.0%, respectively; 12 patients had tumor recurrence. In the non-neoadjuvant chemotherapy group, the median tumor-free survival time was 19 months (10-35 months), and the 1-year and 3-year tumor-free survival rates were 87.3% and 30.0%, respectively. The median postoperative overall survival time was 20 months (10-35 months), the 1-year and 3-year overall survival rates were 87.0% and 18.6%, respectively; 14 patients had tumor recurrence. There was a statistical difference in the tumor-free survival between the two groups ( χ2 = 4.522, P = 0.03), and there was no statistical difference in the overall survival between the two groups ( χ2 = 3.717, P > 0.05). Conclusions:XELOX regimen neoadjuvant chemotherapy is safe and effective for patients with resectable locally advanced Siewert type Ⅱ and Ⅲ adenocarcinoma at the gastroesophageal junction. It can decrease the tumor clinical stage and increase the R 0 resection rate and tumor-free survival rate.

Objective To explore the application value of cone-shaped gastric tube combined with cervical end-to-end anastomosis in thoracoscopic and laparoscopic esophagectomy for esophageal cancer.Methods The retrospective and descriptive study was conducted.The clinical data of 122 patients with esophageal cancer who were admitted to West China Hospital of Sichuan University from December 2016 to December 2017 were collected.There were 89 males and 33 females,aged (61±8)years,with a range from 48 to 81 years.McKeowntype three-incision esophagectomy was performed,and the cone-shaped gastric tube was pulled up to esophagus in left neck for hand-sewn end-to-end anastomosis after the dissection of esophagus and stomach under total thoracoscopy and laparoscopy.Observation indicators:(1) surgical treatment situations;(2) postoperative complications;(3) follow-up.Follow-up using outpatient examination was performed to detect postoperative gastroesophageal reflux,anastomotic stenosis and evaluate anastomotic width at 1,3,6 months and one year postoperatively up to December 2018.Measurement data with normal distribution were represented by Mean±SD.Measurement data with skewed distribution were described by M (P25,P75) or M (range).Count data were expressed by absolute number.Results (1) Surgical treatment situations:122 patients underwent laparocopic McKeown-type three-incision esophagectomy successfully,using cone-shaped gastric tube combined with cervical hand-sewn end-to-end anastomosis as digestive tract reconstruction,with no intraoperative conversion to open surgery.The operation time,cervical anastomosis time,and volume of intraoperative blood loss were (229 ± 49) minutes,(27± 1) minutes,and 50 mL (40 mL,60 mL),respectively.There were 6-8 stations of lymph node dissected,and the number of lymph node dissected were 19 (15,25).Duration of postoperative hospital stay was 10 days (9 days,11 days) in the 122 patients.(2) Postoperative complications:31 of 122 patients had postoperative complications.The primary complications:3 patients with anastomotic fistula were cured by conservative treatment including enteral nutrition through placement of nutritional tube under gastroscope,closed thoracic drainage and anti-infection;6 cases with severe thoracic gastric dilation were cured after gastrointestinal decompression.The secondary complications of 22 patients included 8 cases with hoarseness caused by recurrent laryngeal never injury,5 with arrhythmia,9 with pulmonary infection.They were cured after symptomatic and supportive treatment.No chylothorax occured,and there was no perioperative death.(3) Follow-up:all the 122 patients were followed up for 10-24 months,with a median time of 19 months.During the follow-up,7 cases with anastomotic stenosis including 4 scoring less than grade 2 and 3 scoring more than grade 3 were relieved after dilation through gastroscope.There were 33 of 122 patients without any reflux symptoms,and 89 with reflux symptoms,among which 52 were scored 1,25 were scored 2 and 12 were scored 3.The width of gastroesophageal anastomosis measured by barium radiography at 1 month after operation was (1.2±0.4) cm.Conclusion Coneshaped gastric tube combined with cervical end-to-end anastomosis in digestive tract reconstruction of thoracoscopic and laparoscopic esophagectomy can reduce the incidence of postoperative anastomotic complications and thoracic gastric dilation,and nasogastric tube placement could be abandoned,which demonstrates good safety and universality.

Pharmacoepidemiology refers to the use of epidemiological research methods in studying the application and use of drugs in large populations to evaluate the safety and efficacy of medical products. Therefore, standardized pharmacoepidemiology research is the basis of the above work. Based on systematic reviews of national and international pharmacoepidemiological methodological standards and guidelines, and in combination with Chinese medical and health practice and experts’ opinions, the Professional Committee of Pharmacoepidemiology of Chinese Pharmaceutical Association developed the group standard, guide on methodological standards in pharmacoepidemiology (T/CPHARMA 002-2019), to better guide the work of pharmacoepidemiology. The guideline was designed to provide advice and reference for pharmacoepidemiology research by government, regulatory agencies, research institutions, and pharmaceutical manufacturers in China.

In this study, eight-month-old ectomycorrhizae of Tuber borchii with Corylus avellana were synthesized to explore the influence of T. borchii colonization on the soil properties and the microbial communities associated with C. avellana during the early symbiotic stage. The results showed that the bacterial richness and diversity in the ectomycorrhizae were significantly higher than those in the control roots, whereas the fungal diversity was not changed in response to T. borchii colonization. Tuber was the dominant taxon (82.97%) in ectomycorrhizae. Some pathogenic fungi, including Ilyonectria and Podospora, and other competitive mycorrhizal fungi, such as Hymenochaete, had significantly lower abundance in the T. borchii inoculation treatment. It was found that the ectomycorrhizae of C. avellana contained some more abundant bacterial genera (e.g., Rhizobium, Pedomicrobium, Ilumatobacter, Streptomyces, and Geobacillus) and fungal genera (e.g., Trechispora and Humicola) than the control roots. The properties of rhizosphere soils were also changed by T. borchii colonization, like available nitrogen, available phosphorus and exchangeable magnesium, which indicated a feedback effect of mycorrhizal synthesis on soil properties. Overall, this work highlighted the interactions between the symbionts and the microbes present in the host, which shed light on our understanding of the ecological functions of T. borchii and facilitate its commercial cultivation.

In this study, the mobilomes of nine teleost species were annotated by bioinformatics methods. Both of the mobilome size and constitute displayed a significant difference in 9 species of teleost fishes. The species of mobilome content ranking from high to low were zebrafish, medaka, tilapia, coelacanth, platyfish, cod, stickleback, tetradon and fugu. Mobilome content and genome size were positively correlated. The DNA transposons displayed higher diversity and larger variation in teleost (0.50% to 38.37%), was a major determinant of differences in teleost mobilomes, and hAT and Tc/Mariner superfamily were the major DNA transposons in teleost. RNA transposons also exhibited high diversity in teleost, LINE transposons accounted for 0.53% to 5.75% teleost genomic sequences, and 14 superfamilies were detected. L1, L2, RTE and Rex retrotransposons obtained significant amplification. While LTR displayed low amplification in most teleost with less than 2% of genome coverages, except in zebrafish and stickleback, where LTR reachs 5.58% and 2.51% of genome coverages respectively. And 6 LTR superfamilies (Copia, DIRS, ERV, Gypsy, Ngaro and Pao) were detected in the teleost, and Gypsy exhibits obvious amplication among them. While the SINE represents the weakest ampification types in teleost, only within zebrafish and coelacanth, it represents 3.28% and 5.64% of genome coverages, in the other 7 teleost, it occupies less than 1% of genomes, and tRNA, 5S and MIR families of SINE have a certain degree of amplification in some teleosts. This study shows that the teleost display high diversity and large variation of mobilome, there is a strong correlation with the size variations of genomes and mobilome contents in teleost, mobilome is an important factor in determining the teleost genome size.
