ABSTRACT
Objective@#Previous research has explored a variety of mental disorders associated with Internet Gaming Disoder (IGD) and Social Media Addiction (SMA). To date, few studies focused on the network characteristics and investigated mood and sleep symptoms across SMA and IGD of adolescence at a group-specific level. This study aims to identify different characteristics of IGD and SMA and further determine the group-specific psychopathology process among adolescents. @*Methods@#We conducted a cross-sectional study to recruit a cohort of 7,246 adolescents who were scored passing the cutoff point of Internet Gaming Disorder Scale-Short Form and Bergen Social Media Addiction Scale, as grouped in IGD and SMA, or otherwise into the control group. Patient Health Questionnaire-9, Generalized Anxiety Disorder 7-item, and Pittsburgh Sleep Quality Index were assessed for the current study, and all assessed items were investigated using network analysis. @*Results@#Based on the analytical procedure, the participants were divided into three groups, the IGD group (n=789), SMA group (n=713) and control group (n=5,744). The edge weight bootstrapping analysis shows that different groups of networks reach certain accuracy, and the network structures of the three groups are statistically different (pcontrol-IGD=0.004, pcontrol-SMA<0.001, pIGD-SMA<0.001). The core symptom of SMA is “feeling down, depressed, or hopeless”, while IGD is “feeling tired or having little energy”. @*Conclusion@#Although IGD and SMA are both subtypes of internet addiction, the psychopathology processes of IGD and SMA are different. When dealing with IGD and SMA, different symptoms should be addressed.
ABSTRACT
In the field of dental aesthetics,digital aesthetic design plays a crucial role in helping dentists to predict treatment outcomes vis-ually,as well as in enhancing the consistency of knowledge and understanding of aesthetic goals between dentists and patients.It serves as the foundation for achieving ideal aesthetic effects.However,there is no clear standard for this digital process currently in China and abroad.Many dentists lack of systematic understanding of how to carry out digital aesthetic design for treatment.To establish standardized processes for dental aesthetic design and to improve the homogeneity of treatment outcomes,Chinese Society of Digital Dental Industry(CSD-DI)convened domestic experts in related field to compile this consensus.This article elaborates on the key aspects of digital aesthetic data collection,integration steps,and the digital aesthetic design process.It also formulates a decision tree for dental aesthetics at macro level and outlines corresponding workflows for various clinical scenarios,serving as a reference for clinicians.
ABSTRACT
Establish a production line with controllable process and high intelligence, contribute to improve the quality and production efficiency of aconite processed by microwave, and promote the transformation and application of aconite processed by microwave. According to the principle of aconite detoxification and the characteristics of industrial microwave equipment, an industrial production line of aconite processed by microwave was established with diester alkaloids and monoester alkaloids as indicators, and pilot production was carried out. At the same time, the content of active constituents and efficacy were compared with that of the main processed products, such as Shengfupian, Baifupian and Heishunpian. The results showed that the industrial production of aconite processed by microwave can be divided into two stages: "Liquid seal to detoxification - drying and puffing". The content of monoester alkaloids in 10 batches of aconite processed by microwave was 0.071%-0.166% and the content of diester alkaloids was 0.004%-0.016%, which met the relevant requirements of the Chinese Pharmacopoeia in 2020. Compared with Heishunpian and Baifupian, the retention rate of the effective components of aconite processed by microwave was higher. Pharmacological experiments showed that aconite processed by microwave not only retained the anti-inflammatory and analgesic activities of Heishunpian and Baifupian, but also significantly increased the levels of leukocytes and lymphocytes in mice with liver cancer chemotherapy, enhanced the CD4/CD8 ratio in spleen cells of mice (P < 0.05), thus regulating the body's immunity. However, this effect of Baifupian was weak, while Heishunpian and Shengfupian had no such effect. Through the above research, this study established microwave processing line with controllable process and high intelligence, as well produced the aconite processed by microwave with low toxicity and stable quality. It laid a foundation for the industrialized continuous production and clinical positioning of aconite by microwave processed, and provided scientific support for the development and application of microwave technology in the field of traditional Chinese medicine. All animal experiments in this study were reviewed and approved by the Experimental Animal Ethics Committee of Chengdu University of Traditional Chinese Medicine before being carried out (Approval No. 2020-28).
ABSTRACT
Liquid chromatography-mass spectrometry was employed to analyze the chemical components in Curcuma longa tuberous roots(HSYJ), C. longa tuberous roots processed with vinegar(CHSYJ), and rat serum after the administration. The active components of HSYJ and CHSYJ absorbed in serum were identified based on the secondary spectrum of database and literature. The targets of primary dysmenorrhea was screened out from database. The protein-protein interaction network analysis, gene ontology(GO) functional annotation, and Kyoto Encyclopedia of Genes and Genomes(KEGG) pathway enrichment analysis were performed for the common targets shared by the drug active components in serum and primary dysmenorrhea, and the component-target-pathway network was constructed. AutoDock was used to conduct molecular docking between the core components and targets. A total of 44 chemical components were identified from HSYJ and CHSYJ, including 18 absorbed in serum. On the basis of network pharmacology, we identified 8 core components(including procurcumenol, isobutyl p-hydroxybenzoate, ferulic acid, and zedoarondiol) and 10 core targets \[including interleukin-6(IL-6), estrogen receptor 1(ESR1), and prostaglandin-endoperoxide synthase 2(PTGS2)\]. The core targets were mainly distributed in the heart, liver, uterus, and smooth muscle. The molecular docking results showed that the core components were well bound to the core targets, indicating that HSYJ and CHSYJ may exert therapeutic effect on primary dysmenorrhea via estrogen, ovarian steroidogenesis, tumor necrosis factor(TNF), hypoxia-inducible factor-1(HIF-1), IL-17 and other signaling pathways. This study clarifies the HSYJ and CHSYJ components absorbed in serum, as well as the corresponding mechanism, providing a reference for further elucidating the therapeutic material basis and clinical application of HSYJ and CHSYJ.

Objective:To observe the effect of rhGLP-1 (7-36) on Akt/GSK3 signaling pathway in hepatocytes.Methods:Human HL7702 cell line was cultured to the logarithmic growth stage and divided into experimental group and blank control group. The cultures were incubated with 100nM medium containing rhglp-1 (7-36) and without rhglp-1 (7-36) for 90min. The levels of Akt, Glycogen synthase Kinase 3 (GSK3) and Glycogen synthase (GS) in the two groups were detected by Western Blot.Results:Compared with blank control group, the protein expression of p-Akt (Thr308) in experimental group (1.81±0.28) was significantly increased ( P=0.01), but the protein expression of Akt and p-Akt (Ser473) was not significantly changed. The protein expression levels of p-GSK3α (Ser21) (1.27±0.09) and p-GSK3β (Ser9) (1.24±0.09) in the experimental group were significantly increased ( P=0.003, 0.002), while the protein expression levels of GSK3α and GSK3β were not significantly changed. The protein expression level of p-GS (Ser641) (0.70±0.16) was decreased in the experimental group ( P=0.03), but the protein expression level of GS did not change significantly. Conclusion:Glp-1 can inhibit GSK3/GS signaling pathway, activate GS activity and promote glycogen synthesis.
ABSTRACT
OBJECTIVE@#To investigate the distribution and antimicrobial susceptibility of causative microorganisms recovered from patients with intra-abdominal infections (IAIs).@*METHODS@#A total of 2,926 bacterial and fungal strains were identified in samples collected from 1,679 patients with IAIs at the Peking Union Medical College Hospital between 2011 and 2021. Pathogenic bacteria and fungi were identified using matrix-assisted laser desorption/ionization time-of-flight mass spectrometry. Antimicrobial susceptibility testing (AST) was performed using the VITEK 2 compact system and the Kirby-Bauer method. AST results were interpreted based on the M100-Ed31 clinical breakpoints of the Clinical and Laboratory Standards Institute.@*RESULTS@#Of the 2,926 strains identified, 49.2%, 40.8%, and 9.5% were gram-negative bacteria, gram-positive bacteria, and fungi, respectively. Escherichia coli was the most prevalent pathogen in intensive care unit (ICU) and non-ICU patients; however, a significant decrease was observed in the isolation of E. coli between 2011 and 2021. Specifically, significant decreases were observed between 2011 and 2021 in the levels of extended-spectrum β-lactamase (ESBL)-producing E. coli (from 76.9% to 14.3%) and Klebsiella pneumoniae (from 45.8% to 4.8%). Polymicrobial infections, particularly those involving co-infection with gram-positive and gram-negative bacteria, were commonly observed in IAI patients. Moreover, Candida albicans was more commonly isolated from hospital-associated IAI samples, while Staphylococcus epidermidis had a higher ratio in community-associated IAIs. Additionally, AST results revealed that most antimicrobial agents performed better in non-ESBL-producers than in ESBL-producers, while the overall resistance rates (56.9%-76.8%) of Acinetobacter baumanmii were higher against all antimicrobial agents than those of other common gram-negative bacteria. Indeed, Enterococcus faecium, Enterococcus faecalis, S. epidermidis, and S. aureus were consistently found to be susceptible to vancomycin, teicoplanin, and linezolid. Similarly, C. albicans exhibited high susceptibility to all the tested antifungal drugs.@*CONCLUSION@#The distribution and antimicrobial susceptibility of the causative microorganisms from patients with IAIs were altered between 2011 and 2021. This finding is valuable for the implementation of evidence-based antimicrobial therapy and provides guidance for the control of hospital infections.

Sialyllactose is one of the most abundant sialylated oligosaccharides in human milk oligosaccharides (HMOs), which plays an important role in the healthy development of infants and young children. However, its efficient and cheap production technology is still lacking presently. This study developed a two-step process employing multiple-strains for the production of sialyllactose. In the first step, two engineered strains, E. coli JM109(DE3)/ pET28a-BT0453 and JM109(DE3)/pET28a-nanA, were constructed to synthesize the intermediate N-acetylneuraminic acid. When the ratio of the biomass of the two engineered strains was 1:1 and the reaction time was 32 hours, the maximum yield of N-acetylneuraminic acid was 20.4 g/L. In the second step, E. coli JM109(DE3)/ pET28a-neuA, JM109(DE3)/ pET28a-nst and Baker's yeast were added to the above fermentation broth to synthesize 3'-sialyllactose (3'-SL). Using optimal conditions including 200 mmol/L N-acetyl-glucosamine and lactose, 150 g/L Baker's yeast, 20 mmol/L Mg2+, the maximum yield of 3'-SL in the fermentation broth reached 55.04 g/L after 24 hours of fermentation and the conversion rate of the substrate N-acetyl-glucosamine was 43.47%. This research provides an alternative technical route for economical production of 3'-SL.

This study compared the effects of Curcuma longa before and after processing with vinegar on the rat model of dysmenorrhea with the syndrome of liver depression and Qi stagnation to reveal the mechanism of vinegar processing in improving the role of C. longa in soothing liver and relieving pain. The rat model of dysmenorrhea with the syndrome of liver depression and Qi stagnation was established according to the Preparation of the Animal Model of Dysmenorrhea(Draft) and the chronic unpredictable stress me-thod. The changes in the body weight, organ indexes, writhing latency, writhing score, and serum levels of six liver function indicators, sex hormones, pain factors, and blood rheological indicators were measured to evaluate the efficacy of C. longa processed with vinegar or not in treating dysmenorrhea in the rats with syndrome of liver depression and qi stagnation. Compared with the model group, the C. longa group(processed with vinegar or not) showed slow weight loss, increase in writhing latency, and decrease in writhing response(P<0.05). The inhibition rates on writhing in raw C. longa, vinegar-processed C. longa, and positive groups were 33.780%, 64.611%, and 62.466%, respectively. The significantly higher inhibition rate of the vinegar processing group indicated that vinegar-processed C. longa demonstrated more significant therapeutic effect. The vinegar-processed C. longa group showed lower levels of alanine aminotransferase(ALT), alkaline phosphatase(ALP), aspartate aminotransferase(AST), direct bilirubin(DBIL), and total bilirubin(TBIL) and higher level of albumin(ALB)(P<0.05), which indicated that vinegar processing enhanced the therapeutic effect of C. longa on liver injury. The serum levels of estradiol(E_2) and oxytocin(OT) were lower in the vinegar-processed C. longa group(P<0.05), indicating that the vinegar-processed C. longa could regulate the sex hormone levels, reduce the activity of uterine smooth muscle and contraction of uterus, and alleviate the symptoms of dysmenorrhea in rats. Moreover, the vinegar-processed C. longa group showed lower interleukin-6(IL-6) and arginine vasopressin(AVP) levels and higher beta-endorphin(β-EP) level(P<0.05), which indicated that vinegar-processed C. longa regulated the levels of pain factors to exert the pain-relieving effect. Drug intervention decreased the whole blood viscosity low-cut, medium-cut and high-cut values, plasma viscosity, whole blood reduction viscosity low-cut and high-cut values, erythrocyte cumulative pressure, and equation K value of erythrocyte sedimentation rate(P<0.05), and the vinegar-processed C. longa group outperformed other groups. This result indicated that vinegar processing enhanced the function of C. longa in improving the local blood rheology. C. longa processed with vinegar can enter the liver to relieve the da-mage to the heart, liver, kidney, and uterus, repair the liver function, and recover the sex hormone levels and immune function by regulating the levels of sex hormones and pain factors and improving the blood rheology. It activates the pain-relieving mechanism to relieve the pain, protect the liver, and fight inflammation, which is consistent with the theory that vinegar processing facilitates C. longa entering the liver to sooth liver and relieve pain.
ABSTRACT
Animal survival necessitates adaptive behaviors in volatile environmental contexts. Virtual reality (VR) technology is instrumental to study the neural mechanisms underlying behaviors modulated by environmental context by simulating the real world with maximized control of contextual elements. Yet current VR tools for rodents have limited flexibility and performance (e.g., frame rate) for context-dependent cognitive research. Here, we describe a high-performance VR platform with which to study contextual behaviors immersed in editable virtual contexts. This platform was assembled from modular hardware and custom-written software with flexibility and upgradability. Using this platform, we trained mice to perform context-dependent cognitive tasks with rules ranging from discrimination to delayed-sample-to-match while recording from thousands of hippocampal place cells. By precise manipulations of context elements, we found that the context recognition was intact with partial context elements, but impaired by exchanges of context elements. Collectively, our work establishes a configurable VR platform with which to investigate context-dependent cognition with large-scale neural recording.

Objective: To investigate the expression of TRPS1 in salivary gland-type breast carcinoma and its clinical application. Methods: A total of 30 cases of salivary gland-type breast carcinoma diagnosed from May 2015 to November 2022 at the Department of Pathology of the First Affiliated Hospital of Nanjing Medical University were collected. The expression of TRPS1 was detected by immunohistochemistry and compared with that of GATA3. TRPS1 and GATA3 expression in 24 cases of primary salivary gland carcinoma. Results: There were 10 cases of breast secretory carcinoma, aged 21-61 years (median 53.5 years), with the size ranging from 0.9-2.2 cm (median 1.6 cm), 2 of which were accompanied by axillary nodal macrometastasis. All patients were alive after 2-55 months of follow-up (median 29.5 months, mean 29.7 months). There were 20 cases of breast adenoid cystic carcinoma, aged 36-77 years (median 53.5 years), with the size ranging from 1.2-5.5 cm (median 2.5 cm), 3 of which were accompanied by axillary nodal macrometastasis. All patients were alive after 3-92 months of follow-up (median 22.5 months, mean 31.7 months), and 1 patient had lung metastasis 15 months after surgery. The medium/high expression ratio of TRPS1 in breast secretory carcinoma was 10/10, which was higher than that of GATA3 (7/10). TRPS1 was also positive in the 2 cases with lymph node metastases. The medium/high expression rate of TRPS1 in breast adenoid cystic carcinoma was 20/20, which was significantly higher than that of GATA3 (2/20). TRPS1 was highly expressed in both classic and solid subtypes, while GATA3 was only expressed in a few cases of the classic subtype. TRPS1 was also positive in 3 cases with lymph node metastases and 1 case of the pulmonary metastases. The expression level of TRPS1 was the same in 1 case before and after neoadjuvant chemotherapy. In addition, TRPS1 was positive in parotid secretory carcinoma and adenoid cystic carcinoma. The medium/high expression rate of TRPS1 in parotid secretory carcinoma (6/6) was higher than that of GATA3 (2/6), and the medium/high expression rate of TRPS1 in parotid adenoid cystic carcinoma (17/18) was higher than that of GATA3 (2/18). Conclusions: The expression of TRPS1 is highly sensitive to salivary gland-type breast carcinoma, especially in GATA3-negative solid subtype of adenoid cystic carcinoma, which plays an important role in clinical practice.

ABSTRACT
Objective:To explore the effectiveness of stratified teaching in improving the efficiency and quality of clinical teaching in the standardized training of residents in the department of prosthodontics.Methods:We enrolled a total of 297 participants who accomplished the standardized residency training in the Department of Prosthodontics of the Ninth People's Hospital Affiliated to Shanghai Jiao Tong University School of Medicine from January 2020 to May 2023. They were divided into stratified group (141 trainees from September 2021 to May 2023) and control group (156 trainees from January 2020 to August 2021). The stratified group received stratified teaching at three levels according to the trainees' major, training stage, and identity category, and the teaching theme and teaching method were set according to teaching objectives. The control group used a traditional teaching mode. The two groups were compared in terms of medical history taking, oral examination, case analysis, skill practice, and case report scores. SPSSAU was used to perform the t test and chi-squared test for data analysis. Results:The stratified group showed better performance in the final assessment: the case analysis score of the first-level trainees was significantly higher than that of the control group (85.72±4.14 vs. 83.00±6.38, P=0.003); the second-level trainees had a higher medical history taking score than the control group (88.20±7.14 vs. 85.38±5.63); the proportions of trainees rated as excellent in case report in the stratified group (the first level, 54.02%; the second level, 52.63%; the third level, 75.00%) were higher than those in the control group (the first level, 42.65%; the second level, 45.33%; the third level, 46.15%). Conclusions:In standardized residency training, the stratified teaching method can effectively improve trainees' case analysis, medical history taking, and case report abilities, and the effects in improving the skill practice level of trainees majoring in prosthodontics need to be further explored.
ABSTRACT
BACKGROUND@#To investigate the correlation between the reduction of lung volume and the degree of lung function damage after lobectomy.@*METHODS@#A total of 131 patients (72 males and 59 females) who underwent thoracoscopic lobectomy in the First Affiliated Hospital of Suzhou University from January 2019 to July 2020 (including thoracoscopic resection of left upper lobe, left lower lobe, right upper lobe, right middle lobe and right lower lobe). In order to compare the difference between postoperative pulmonary function and preoperative pulmonary function, the pulmonary function measurements were recorded at 7 days before operation, and 3 months, 6 months and 1 year after operation. Forced expiratory volume in 1 second (FEV1) was used as the main evaluation parameter of pulmonary function. The original lung volume and the remaining lung volume at each stage were calculated by Mimics Research 19.0 software. The correlation between lung volume and lung function was analyzed.@*RESULTS@#FEV1 in postoperative patients was lower than that before operation, and the degree of decline was positively correlated with the resection volume of lung lobes (the maximum value was shown in the left lower lobe group). Significantly, there was no significant difference in the degree of pulmonary function reduction between 3 months, 6 months and 1 year after operation.@*CONCLUSIONS@#The decrease of lung tissue volume after lobectomy is the main reason for the decrease of lung function, especially in the left lower lobe. And 3 months after lobectomy can be selected as the evaluation node of residual lung function.

Exosomes are extracellular vesicles secreted by cells with a variety of molecular components, which can play the role of substance transport and signal communication between cells through autocrine and paracrine. Exosomes exist widely in vivo and participate in many physiological and pathological processes, including force-related periodontal inflammation. There are stress receptor cells in the periodontium, which can sense force loading on the tooth. An appropriate amount of mechanical loading can maintain health of the periodontium, while excessive mechanical loading may cause destruction and absorption of the periodontium, leading to periodontal inflammation. This article reviews the role of exosomes in force-related inflammation response, especially in periodontal inflammation response.
ABSTRACT
Objective To analyze the polymorphism of Plasmodium lactate dehydrogenase (pLDH) gene and predict B-cell epitopes in pLDH peptides in four species of human malaria parasites. Methods The blood samples and epidemiological characteristics were collected from malaria cases in Yunnan Province registered in the National Notifiable Disease Report System. The pLDH genes of four human Plasmodium species were amplified using nested PCR assay and sequenced. The polymorphisms of pLDH genes was analyzed using the software MEGA version 7.0.26 and DnaSP version 5.10, and the B-cell epitopes were predicted in pLDH peptides using the Immune Epitope Database (IEDB). Results The sequences of P. vivax LDH (PvLDH), P. falciparum LDH (PfLDH), P. ovale LDH (PoLDH) and P. malariae LDH (PmLDH) genes were obtained from 153, 29, 17 and 11 blood samples from patients with P. vivax, P. falciparum, P. ovale and P. malariae malaria, respectively, which included 15, 2, 4 and 2 haplotypes and had a nucleotide diversity (π) of 0.104. A high level of intra-species differentiation was seen in the PoLDH gene (π = 0.012), and the π values were all < 0.001 for PvLDH, PfLDH and PmLDH genes. Active regions of B-cell antigen were predicted in the pLDH peptide chain of four human malaria parasites, of 4 to 5 in each chain, and the activity score was approximately 0.430. Among these peptide chains, the “86-PGKSDKEWNRD-96” short-peptide was a B-cell epitope shared by all four species of human malaria parasites, and the “266-GQYGHS (T)-271” short-peptide was present in PvLDH and PoLDH peptide chains, while “212-EEVEGIFDR-220” was only found in the PvLDH peptide chain, and “208-LISDAE-213” was only seen in the PfLDH peptide chain. Conclusions The PoLDH gene polymorphism may be derived from the weak negative purification selection, while PvLDH, PfLDH and PmLDH genes may maintain a relatively conservative state. There may be two B-cell epitopes “212-EEVEGIFDR-220” and “208-LISDAE-213” in the proximal region of the C terminal in the pLDH peptide chain, which is feasible to differentiate between P. vivax and P. falciparum infections.
ABSTRACT
Objective:To analyze the correlation between saliva glucose and blood glucose level by measuring the concentration of saliva with high-precision ion chromatograph, and further to provide the clinical data for saliva glucose as an auxiliary index of blood glucose monitoring.Methods:A total of 268 subjects with normal glucose metabolism (NGT) and diabetes mellitus (DM) were enrolled and fasting venous blood and saliva samples were collected at the same time. The levels of saliva glucose, blood glucose and glycosylated hemoglobin (HbA1c) were measured by ion chromatograph, automatic biochemical analyzer and glycosylated hemoglobin analyzer, respectively. Methods of Kruskal-Wallis H test was used for comparison between groups, and the Spearman correlation was used for correlation analysis. Results:The mean values of blood glucose, saliva glucose and HbA1c in the DM group are all higher than those in the NGT group, and the differences are all statistically significant ( P<0.05). Saliva glucose cut-off points are set at 10, 15, 20 and 25 mg/L, respectively. When the saliva glucose concentration is greater than or equal to the above cut-off points, the saliva glucose level are positively correlated with the blood glucose level ( r=0.321, 0.379, 0.509 and 0.428, respectively, P<0.05) . Conclusion:The level of saliva glucose in DM is significantly higher than that in NGT. When the concentration of saliva glucose is greater than 20 mg/ L, there is a significant positive correlation between saliva glucose and blood glucose, and the max correlation coefficient r is 0.509.
ABSTRACT
Objective:To explore the effect of ADOPT mode nursing intervention on airway self-care ability in patients with total laryngectomy.Methods:50 patients who received total laryngectomy were randomly divided into control group (25 cases) and observation group (25 cases). The control group received routine nursing, while the observation group received ADOPT mode nursing intervention on the basis of routine nursing. The Exercise of Self-Care Agency Scale and self-made airway self-care knowledge questionnaire were used to evaluate the airway self-care ability and the incidence of airway related complications was also evaluated.Results:On discharge and 3 months after discharge, total scores about self-care knowledge of airway were 83.80 ± 5.06 and 89.40 ± 4.86 in the experimental group, which were significantly higher than those in the control group (68.75 ± 5.57, 72.50 ± 6.76), the differences were statistically significant ( t = -9.91, -10.09, both P<0.05). On discharge and 3 months after discharge, total scores in ESCA were 126.88 ± 9.77 and 133.60 ± 8.10 in the experimental group, which were significantly higher than those in the control group (113.29 ± 17.06 and 119.13 ± 15.30). The differences were significant ( t = -3.42, -4.12, both P<0.05). The incidence of airway complications was 41.67% (10/24) in the control group and 12.00%(3/25) in the observation group, which was statistically significant ( χ2 = 5.53, P<0.05). Conclusions:ADOPT mode nursing intervention can significantly improve the airway self-care ability of patients with total laryngectomy, reduce the incidence of airway complications, and is beneficial to patients′ physical and mental recovery.
ABSTRACT
Objective: To compare the short-term efficacy and long-term prognosis of laparoscopic and laparotomy radical resection for gallbladder cancer(GBC). Methods: From January 2010 to December 2020,the clinical data and survival information for 133 patients who underwent radical resection of GBC at the Department of Hepatopancreatobiliary Surgery,Zhejiang Provincial People's Hospital,were retrospectively collected. Eighty patients(23 males and 57 females) underwent laparoscopic radical resection and had a median age(M(IQR)) of 66.0(12.8)years(range:28.0 to 82.0 years). Fifty-three patients(45 males and 8 females) who received laparotomy were 63.0(6.0)years old(range:45.0 to 80.0 years old). There were no significant differences in age,gender,body mass index,preoperative albumin,preoperative total bilirubin,N stages,vascular invasion,peri-neural invasion or tumor differentiation between the laparoscopic and laparotomy group(all P>0.05). But there were significant differences in preoperative CA19-9(Z=-2.955, P=0.003), preoperative ALT level(Z=-2.801,P=0.031) and T stage (χ2=19.110,P=0.007) between the two groups. A non-parametric test was used for quantitative data. χ2 test or Fisher exact probability method was used for count data. Results: Patients in the laparoscopic group did not differ from those in the laparotomy group in terms of length of operation,number of lymph node yield,number of positive lymph nodes,the incidence of intraoperative gallbladder rupture,incidence of postoperative bile leakage,abdominal bleeding or abdominal infection,30-day mortality,90-day mortality, the incidence of incision implantation or peritoneal cavity metastasis(all P>0.05). Patients in the laparoscopic group showed less intraoperative bleeding(100.0(200.0)ml vs. 400.0(250.0)ml)(Z=-5.260,P<0.01),fewer days with drainage tube indwelling(6.0(3.8)days vs. 7.0(4.0)days)(Z=-3.351, P=0.001), and fewer postoperative days in hospital(8.0(5.0)days vs. 14.0(7.5)days)(Z=-6.079,P<0.01) than those in the laparotomy group. Patients in the laparoscopic group displayed better overall survival (P<0.01) and progression-free survival (P<0.01). Subgroup analysis for GBC of T1b-T2 and T3 stages revealed comparable overall survival and progression-free survival between the laparoscopic and laparotomy groups (P>0.05). Conclusions: Laparoscopic radical resection can achieve long-term survival for GBC comparable to that with open surgery. Laparoscopic radical resection has advantages over open surgery regarding surgical trauma and postoperative recovery.

ObjectiveTo observe the clinical efficacy and safety of Chinese medicinal mixture for dispelling stasis and resolving phlegm combined with western medicine in the treatment of epilepsy combined with cognitive impairment by randomized, double-blind, placebo-controlled, parallel-group trial. MethodA total of 123 inpatients and outpatients with epilepsy complicated with cognitive impairment admitted to the department of neurology at Longhua Hospital from October 2020 to October 2021 were randomly assigned into a control group (62 cases, carbamazepine + placebo) and a treatment group (61 cases, carbamazepine + Quyu Dingxian Zhengtong mixture) by random number table method. In the treatment group, 4 cases were exfoliated and eliminated. In the control group, 3 cases fell off. Finally, 57 cases in the treatment group and 59 cases in the control group were included. The total course of treatment for both groups was 12 weeks. The clinical efficacy, efficacy for traditional Chinese medicine (TCM) syndromes, and incidence of adverse reactions were compared between two groups. The changes of seizure frequency, abnormal rate of electroencephalogram (EEG), cognitive function score, serum homocysteine (HCY), folic acid, and vitamin B12 (B12) were measured and compared before and after treatment. ResultAfter 12 weeks of treatment, the treatment group had higher clinical efficacy [92.98% (53/57) vs 79.66% (47/59), χ2=4.327, P<0.05] and efficacy for TCM syndromes [96.49% (55/57) vs 84.75% (50/59), χ2=4.660, P<0.05] than the control group. The treatment group was superior to the control group in reducing the seizure frequency (Z=-3.938, P<0.01) and improving the Montreal cognitive assessment (MoCA) score (t=4.333, P<0.01) and mini-mental state examination (MMSE) score (t=9.531, P<0.01). The variations in serum HCY, folic acid, and B12 in the treatment group were less than those in the control group (t=-7.233, t=-7.972, t=-6.871, P<0.01). After treatment, the abnormal rate of EEG in the treatment group was lower than that in the control group (χ2=4.437, P<0.05). The incidence of adverse reactions in the treatment group (1.75%, 1/57) was lower than that (13.56%, 8/59) in the control group (corrected χ2=4.116, P<0.05). ConclusionChinese medicinal mixture for dispelling stasis and resolving phlegm in combination with western medicine had better efficacy and safety than western medicine alone in the treatment of epilepsy complicated with cognitive impairment. Specifically, the combination outperformed western medicine alone in terms of clinical efficacy, efficacy for TCM syndromes, reduction in seizure frequency, abnormal rate of EEG, adverse reactions, improvement of cognitive function, and variations in serum folic acid, B12, and HCY values. Chinese medicinal mixture for dispelling stasis and resolving phlegm may improve the clinical efficacy and safety by changing the metabolism of folic acid, B12, and HCY in serum of the patients with epilepsy complicated with cognitive impairment.
ABSTRACT
Objective:To observe the effect of Wuzi Yanzong Wan made of different processed products on the apoptosis of spermatogenic cells in rats with kidney essence deficiency, and explore its protective effect on spermatogenic cells. Method:SD rats were randomly divided into the blank group, model group, whole raw product group, pharmacopoeia group and salt-processed product group, with 8 rats in each group. The kidney essence deficiency model was replicated by giving tripterygium glycoside tablets (the dose of 20 mg·kg<sup>-1</sup>). The flow cytometry (FCM) was used to analysis the apoptosis of spermatogenic cells in testis, the immunohistochemistry (IHC) and Western blot were used to detect the expression levels of B-cell lymphoma-2 (Bcl-2) and Bcl-2 associated X protein (Bax) in the testis. High performance liquid chromatography (HPLC) was used to compare the contents of eight components (chlorogenic acid, ellagic acid, hyperoside, isoquercitrin, verbascoside, astragalin, kaempferol and schisandrin) in Wuzi Yanzong Wan made of different processed products, the mobile phase was composed of acetonitrile (A)-0.4% phosphoric acid aqueous solution (B) for gradient elution (0-5 min, 5%-15%A; 5-10 min, 15%-17%A; 10-25 min, 17%A; 25-35 min, 17%-26%A; 35-60 min, 26%-56%A), the detection wavelength was set at 254 nm. Result:Compared with the model group, the total apoptosis rate of spermatogenic cells, protein expression of Bax and Bcl-2 in each administration group were improved. Among them, the pharmacopoeia group and salt-processed product group had significant effects (<italic>P</italic><0.01), and the improvement effect of the pharmacopoeia group and salt-processed product group was significantly better than that of the whole raw product group (<italic>P</italic><0.05). The contents of chlorogenic acid, hyperoside, isoquercitrin and verbascoside in Wuzi Yanzong Wan were increased after the herbal medicines being processed with salt-water. The content of ellagic acid in the salt-processed product group increased, while it decreased in the pharmacopoeia group. The contents of verbascoside, astragalin, kaempferol and schisandrin in samples from the salt-processed product group were greater than those in samples from the pharmacopoeia group. Conclusion:Wuzi Yanzong Wan may reduce the apoptosis of spermatogenic cells in rat testis by inhibiting the expression of Bax and promoting the expression of Bcl-2, and exert its effect of nourishing kidney and enriching essence. The enhanced anti-spermatogenic effect of Wuzi Yanzong Wan after processing may be related to the changes in chemical composition content after processing.
