Objective: Exploring the mediating effect of perceived social support between the maternal personality traits and pregnancy-related anxiety. Methods: Singleton pregnant women who underwent antenatal checkups in the obstetrics department of general hospital affiliated to Ningxia Medical University from July to December 2021 were enrolled in this study to investigate perceived social support, pregnancy-related anxiety and conscious personality traits. Pearson correlation analysis was used to analyze the association between the maternal personality traits, perceived social support, and pregnancy-related anxiety, and the mediating effect of perceived social support was analyzed using Bootstrap method. Results: A total of 1 259 subjects were included in the study, of which 170 (13.50%) pregnant women felt introverted. The total score of perceived social support was (46.37±8.38), and 31.45% of pregnant women had high perceived social support. The total score of pregnancy-related anxiety was (21.48±5.53). The score of worry about fetal health was (10.09±3.24), and 368 (29.23%) of pregnant women had pregnancy-related anxiety. Maternal personality traits and pregnancy-related anxiety were negatively correlated (r=-0.076, P<0.05) and positively correlated with perceived social support during pregnancy (r= 0.127, P<0.05). Perceived social support during pregnancy and pregnancy-related anxiety were negatively correlated (r=-0.236, P<0.05). Perceived social support partially mediated the relationship between the maternal personality traits and pregnancy-related anxiety, with a relative effect value of 37.50%. Conclusion: The maternal personality traits, level of perceived social support and pregnancy-related anxiety are all related. Perceived social support could mediate the relationship between the maternal personality traits and pregnancy-related anxiety.

Objective: To evaluate the effects on short-term clinical outcomes and long-term quality of life of laparoscopic-assisted radical proximal gastrectomy with esophageal gastric tube anastomosis versus total gastrectomy with Roux-en-Y anastomosis for adenocarcinoma of the esophagogastric junction. Methods: This was a propensity score matching, retrospective, cohort study. Clinicopathological data of 184 patients with adenocarcinoma of the esophagogastric junction admitted to two medical centers in China from January 2016 to January 2021 were collected (147 in the First Affiliated Hospital of Xiamen University and 37 in the Affiliated Hospital of Qinghai University). All patients had undergone laparoscopic-assisted radical gastrectomy. They were divided into two groups based on the extent of tumor resection and technique used for digestive tract reconstruction. A proximal gastrectomy with reconstruction by esophageal gastric tube anastomosis group comprised 82 patients and a total gastrectomy with reconstruction by Roux-en-Y anastomosis group comprised 102 patients. These groups differed significantly in the following baseline characteristics: age, preoperative hemoglobin, preoperative albumin, tumor length, tumor differentiation, and tumor TNM stage (all P<0.05). To eliminate potential bias caused by unequal distribution between the two groups, 1∶1 matching was performed by the nearest neighbor matching method. The 13 matched variables comprised sex, age, height, body mass, body mass index, preoperative glucose, preoperative hemoglobin, preoperative total protein, preoperative albumin, neoadjuvant radiotherapy, tumor length, degree of differentiation, and pathological TNM stage. Postoperative complications, postoperative nutritional status, incidence of reflux esophagitis 1 year after surgery, and quality of life were compared between the two groups. Results: After propensity score matching, 60 patients each were enrolled in the proximal gastrectomy with esophageal gastric tube anastomosis and total gastrectomy with Roux-en-Y anastomosis groups. The baseline characteristics were comparable between these groups (all P>0.05). There were no significant differences between the two groups in operative time, intraoperative bleeding, time to semifluid diet, postoperative hospital days, tumor length, and total hospital costs (P>0.05). Patients in the proximal gastrectomy with esophageal gastric tube anastomosis group had earlier postoperative gastric tube and abdominal drainage tube removal time than those in the total gastrectomy with Roux-en-Y anastomosis group (t=-2.183, P=0.023 and t=-4.073, P<0.001, respectively). In contrast, significantly fewer lymph nodes were cleared and significantly fewer lymph nodes were positive in the proximal gastrectomy with esophageal gastric tube anastomosis group than in the total gastrectomy with Roux-en-Y anastomosis group (t=-5.754, P<0.001 and t=-2.575, P=0.031, respectively). The incidence of early postoperative complications was 43.3% (26/60) in the total gastrectomy with Roux-en-Y anastomosis group; this is not significantly higher than the 26.7% (16/60) in the proximal gastrectomy with esophageal gastric tube anastomosis group (χ²=3.663，P=0.056). The incidences of pulmonary infection (31.7%, 19/60) and pleural effusion (30.0%, 18/60) were significantly higher in the total gastrectomy with Roux-en-Y anastomosis group than in the proximal gastrectomy with esophageal gastric tube anastomosis group (13.3%, 8/60 and 8.3%, 5/60, respectively); these differences are significant (χ²=8.711, P=0.003 and χ²=11.368, P=0.001, respectively). All early complications were successfully treated before discharge. The incidence of long-term postoperative complications was 20.0% (12/60) in the total gastrectomy with Roux-en-Y anastomosis group and 35.0% (21/60) in the proximal gastrectomy with esophageal gastric tube anastomosis group; this difference is not significant (χ²=3.386，P=0.066). The incidence of reflux esophagitis was 23.3% (14/60) in the proximal gastrectomy with esophageal gastric tube anastomosis group; this is significantly higher than the 1.7% (1/60) in the total gastrectomy with Roux-en-Y anastomosis group (χ²=12.876, P<0.001). Body mass index had decreased significantly in both groups 1 year after surgery compared with preoperatively; however, the difference between the two groups was not significant (P>0.05). The differences in hemoglobin and albumin concentrations between 1 year postoperatively and preoperatively were not significant (both P>0.05). Quality of life was assessed using the Visick grade. Visick grade I dominated in both groups. The percentage of patients with Visick II and III in the total gastrectomy with Roux-en-Y anastomosis group was 11.7% (7/60), which is significantly lower than the 33.3% (20/60) in the proximal gastrectomy with esophageal gastric tube anastomosis group (χ²=8.076, P=0.004). No patients in either group had a grade IV quality of life. Conclusions: Both proximal gastrectomy with esophageal gastric tube anastomosis and total gastrectomy with Roux-en-Y anastomosis laparoscopic-assisted radical surgery for adenocarcinoma of the esophagogastric junction are safe and feasible. However, both procedures have their own advantages and disadvantages in terms of postoperative complications. The incidence of reflux esophagitis is higher after proximal gastrectomy with esophageal gastric tube anastomosis, whereas the long-term quality of life is lower than that of patients after total gastrectomy with Roux-en-Y anastomosis.

Pulmonary nodule is a key window for moving ahead the diagnosis and treatment of lung cancer. Traditional Chinese medicine （TCM） can delay the transformation of lung nodules into lung cancer， improve the prognosis of patients， effectively fill the treatment gap during the follow-up period of pulmonary nodules， and has been applied it in the whole cycle and multi-dimensional management of pulmonary nodules. This paper discussed the construction ideas and feasible paths of the whole process management diagnosis and treatment system of pulmonary nodules in TCM， proposed the diagnosis and treatment database of TCM for pulmonary nodules based on the social module of “family-community-hospital”. Through artificial intelligence， we can develop， improve and promote the multi-level and multi-modal “disease-symptom combination” risk prediction model and effectiveness evaluation system of pulmonary nodules. At the same time， the biological connotation of the prevention and treatment of pulmonary nodules by TCM is excavated， which provided empirical evidence for the construction of TCM diagnosis and treatment system， in order to further improve the quality and diagnosis and treatment level of the whole course management of pulmonary nodules.

The awake prone position plays an important role in the treatment of hypoxemia and the improvement of respiratory distress symptoms in non-intubated patients. It is widely used in clinical practice because of its simple operation, safety, and economy. To enable clinical medical staff to scientifically and normatively implement prone position for awake patients without intubation, the committees of consensus formulation, guided by evidence-based methodology and Delphi method, conducted literature search, literature quality evaluation and evidence synthesis around seven topics, including indications and contraindications, evaluation, implementation, monitoring and safety management, termination time, complication prevention and health education of awake prone position. After two rounds of expert letter consultation, Expert consensus on implementation strategy of awake prone positioning for non-intubated patients in China (2023) was formulated, and provide guidance for clinical medical staff.

Objective To observe the effect of Tongxie Yaofang-containing serum on the cell cycle and apoptosis of colon cancer HCT116 cells,and to explore its possible biological mechanism.Methods Colon cancer HCT116 cells were divided into blank group and Tongxie Yaofang-containing serum group with different concentrations.Cell proliferation and activity detection-8(CCK8)was used to detect the effect of each group on the viability of HCT116 cells at 24,48 and 72 h;Flow cytometry was used to detect the apoptosis and cycle arrest of HCT116 cells induced by different concentrations of Tongxie Yaofang-containing serum;Western blot was used to detect the protein expression level of Cell Cycle Regulatory Protein P21(P21),Cyclin B1,cyclin-dependent protein kinases-1(CDK1),B-lymphoma-2(Bcl-2),Bcl-2-related X protein(Bax),phosphatidylinositol-3-kinase(PI3K),phosphorylated phosphatidylinositol-3-kinase(p-PI3K),protein kinase B(Akt)and phosphorylated protein kinase B(p-Akt)after different concentrations of Tongxie Yaofang-containing serum intervention.Results CCK8 showed that compared with the 10%blank group,10%Tongxie Yaofang-containing serum had a significant inhibitory effect on the viability of HCT116 cells only at 48 h(P<0.01);Compared with the 20%blank group,20%Tongxie Yaofang-containing serum could inhibit the viability of HCT116 cells at 48 and 72 h(P<0.01,P<0.05),and the increase of blank serum will not inhibit the viability of HCT116 cell,so 10%blank serum and 48 h were selected as the drug control and intervention time in the subsequent experiment.Flow Cytometry showed that,compared with the blank group,10%and 20%Tongxie Yaofang-containing serum could arrest HCT116 cell cycle in G2/M phase after 48 h of intervention(P<0.01),and induce HCT116 cell apoptosis.At the same time,Western blot showed that Tongxie Yaofang-containing serum could increase the expression of P21 and Bax to varying degrees,and reduces Cyclin B1,CDK1,Bcl-2,p-PI3K,p-Akt expression(P<0.05,P<0.01).Conclusion Tongxie Yaofang can inhibit the proliferation and induce apoptosis of colon cancer HCT116 cells,and its mechanism may be related to the inhibition of PI3K/Akt signaling pathway.

Acephalic spermatozoa syndrome is a rare type of teratozoospermia that severely impairs the reproductive ability of male patients, and genetic defects have been recognized as the main cause of acephalic spermatozoa syndrome. Spermatogenesis and centriole-associated 1 like (SPATC1L) is indispensable for maintaining the integrity of sperm head-to-tail connections in mice, but its roles in human sperm and early embryonic development remain largely unknown. Herein, we conducted whole-exome sequencing (WES) of 22 infertile men with acephalic spermatozoa syndrome. An in silico analysis of the candidate variants was conducted, and WES data analysis was performed using another cohort consisting of 34 patients with acephalic spermatozoa syndrome and 25 control subjects with proven fertility. We identified biallelic mutations in SPATC1L (c.910C>T:p.Arg304Cys and c.994G>T:p.Glu332X) from a patient whose sperm displayed complete acephalia. Both SPATC1L variants are rare and deleterious. SPATC1L is mainly expressed at the head-tail junction of elongating spermatids. Plasmids containing pathogenic variants decreased the level of SPATC1L in vitro. Moreover, none of the patient's four attempts at intracytoplasmic sperm injection (ICSI) resulted in a transplantable embryo, which suggests that SPATC1L defects might affect early embryonic development. In conclusion, this study provides the first identification of SPATC1L as a novel gene for human acephalic spermatozoa syndrome. Furthermore, WES might be applied for patients with acephalic spermatozoa syndrome who exhibit reiterative ICSI failures.

Objective: To investigate whether the contralateral normal external auditory canal (EAC) skin graft can maintain the ear canal health after EAC reconstruction in unilateral congenital aural atresia (CAA) cases. Methods: A Zelen design randomized controlled study was used to collect unilateral CAA patients for EAC reconstruction prospectively (clinical trial registration number: ChiCTR2000032103). The patients were randomly divided into the control group and the trial group. The trial group used the contralateral normal EAC skin graft group (transplant part of the contralateral normal EAC skin to repair the atresia side for unilateral CAA patients), the control group all used scalp blade thick skin. We observed the EAC health and hearing results of the two groups after EAC reconstruction. Results: A total of 13 cases were enrolled from July 2020 to August 2021. There were eight patients in the trial group, including six males and two females, with an average age of 22.3 years (14-36 years). There were two patients with CAA on the left and six patients on the right. The average follow-up time was 8.8 months (4-14 months). There were five patients in the control group, all cases were male with an average age of 16.2 years (12-20 years). There were four patients with CAA on the left and one patient on the right. The average follow-up time was 7.0 months (2-14 months). In the trial group, eight cases of reconstructed EAC epithelium were healthy, one patient had cicatricial stenosis of EAC opening and lateralization of the tympanic membrane. The other patient had cicatricial stenosis of reconstructed EAC, this case also had scar hyperplasia of the contralateral EAC opening but recovered after soft packing and triamcinolone acetonide injection treatment. The healthy side EAC of the rest trial group had no scarring stenosis or local bone hyperplasia during long-term follow-up. In the control group, one patient was lost to follow-up and the other four patients had dry ears of reconstructed EAC, but easily to form crusts and needed to be cleaned repeatedly, one patient had lateralization of the tympanic membrane, the EAC epithelium was not healthy for long-term follow-up. The incidence of complications related to EAC reconstruction was lower than previous studies (χ²=5.55, P=0.018), and the average postoperative Air-Bone Gap increased (18.8±10.0)dB. Conclusion: By optimizing the EAC reconstruction technology, the health of the reconstructed EAC is improved compared with the previous study. After active intervention and treatment, there should be no scarring stenosis or local bone hyperplasia on the contralateral side EAC.

Adulterants and counterfeits were found in some of the commercial traditional Chinese medicine (TCM) decoctions in Hongjin Xiaojie Jiaonang, Hongjin Xiaojie Pian, and Chaihuang Keli during the national drug sampling inspection. However, it was difficult to determine the species of the adulterants and counterfeits by conventional testing methods. Therefore, a total of 184 samples of the TCM decoctions and raw materials belong to the prescriptions of above mentioned traditional Chinese patent medicines, including Bupleuri Radix, Bajiaolian, Heimayi, and Shufuchong, were collected and authenticated by DNA barcoding technology. 111 ITS2 sequences were obtained from 115 commercial TCM decoctions and raw materials of Bupleuri Radix, among which 71 were Bupleurum chinense, three were B. scorzonerifolium, and 31 were closely related species in the same genus. In addition, counterfeits derived from different genera, such as Ailanthus altissima (one sample), Saposhnikovia divaricate (two samples), and Solidago decurrens (three samples), were also detected. 21 ITS2 sequences were obtained from 22 commercial TCM raw materials of Bajiaolian, among which 15 were Diphylleia sinensis and six were Dysosma versipellis and other species in genus Dysosma. For 22 Heimayi samples, PCR amplification of COI sequence was failed due to genomic DNA degradation. Among 38 Shufuchong samples, 24 COI sequences were obtained and only nine of them were the genuine species (Armadillidium vulgare) recorded in the Chinese Pharmacopoeia, 11 were Porcellio laevis, two were Mongoloniscus sinensis, and two samples could not be identified due to the limitation of database. This study demonstrates that DNA barcoding technology is suitable for the species authentication of the decoctions of traditional Chinese patent medicine prescription. It is a conductive way for the establishment of traceability system for the whole TCM industrial chain.

The present work is to analyze the HPLC fingerprints of mulberry-sourced materials(Mori Ramulus, Mori Folium, Muri Cortex, Mori Fructus) using the fingerprint division total statistical moment method and information entropy, and to study the diffe-rences of the chemical components and the overall characteristics of the imprinting template in different parts of mulberry-sourced medicinal materials, so as to provide the basis for finding the effective substances in response to "homologous and different effect" of mulberry(Morus alba). The fingerprints of 24 batches of mulberry-related materials, such as Mori Ramulus, Mori Folium, Muri Cortex, Mori Fructus, were established, and the similarities and differences of the fingerprints were analyzed by calculating the division total statistical moment parameters and information entropy. The AUC_T, MCRT_T, VCRT_T and H values of 24 batches of mulberry-sourced materials were less than 0.05, with significant difference. Among them, all samples showed absorption peaks within 3-11, and 20-24 min, indicating that the four types had the identical or similar chemical composition in the same time period. After 34 min, none of the four types showed absorption peaks. Greater VCRT_T value of the fingerprints of the four kinds was observed at the retention time ranges of 3-4, 16-18, 25-27, and 31-32 min, indicating that the components of the four kinds were significantly different in these time periods; and VCRT_T value of the mulberry was significantly higher than that of the other three kinds of medicinal materials at the retention time windows of 3-4 and 15-17 min; the VCRT_T value of the mulberry white skin was significantly higher at the time windows of 8-10 and 28-30 min; the VCRT_T value of all four kinds was significantly higher within 21-23 min, indicating that the four herbs contain the same or similar components in the chromatogram during this period, but there may be significant differences between the content and the proportion. In addition, the information entropy of mulberry branches is the largest at 7-12, 23-27 min, and that of mulberry fruits is the largest at 2-8 min, which indicates that the components of mulberry branches and mulberry fruits respond greatly in the corresponding period of time, which is also the main peak period of their chemical components. For the chemical components and corresponding efficacy here. The results showed that there are significant differences in the components and contents of mulberry-sourced medicinal materials. The division total statistical moment and information entropy of the total amount of segments can be used to analyze the differences in the components of "homology and different effects", which could provide a more comprehensive analysis method for the determination of quality markers.
