Objective: To analyze the correlation between ABO blood group compatibility and the risk of early complications after liver transplantation, and to identify risk factors for clinical intervention. Methods: Clinical data of 404 liver transplant recipients and donors were collected. Based on donor-recipient ABO matching, patients were divided into three groups: ABO-Identical (ABO-Id, n=313), ABO-compatible (ABO-c, n=68), ABO-incompatible (ABO-i, n=23). Clinical data, early complications, and associated risk factors were compared. Results: Compared with the ABO-Id, ABO-c and ABO-i recipients were younger, had a higher proportion of primary biliary atresia, and more frequently received living-donor transplantation from relatives (P<0.05). Overall complication rates were: ABO-c 47.1% (32/68), ABO-i 43.5% (10/23), ABO-Id 39.3% (123/313), with no significant intergroup difference (P>0.05). Infection was the most common complication [ABO-c 30.9% (21/68), ABO-i 21.7% (5/23), ABO-Id 17.9% (56/313)]. No significant differences were found in infection, vascular/biliary or acute kidney injury/renal failure among the three groups (P>0.05). However, ABO-c group had significantly higher rates of ascites/abscess (20.6% vs 8.9%, P<0.05) and pleural effusion (14.7% vs 7.0%, P<0.05) than ABO-Id group. There was no significant difference in the incidence of complications and ABO blood group between ABO non-Identical (ABO-c and ABO-i) and Identical groups. Logistic regression analysis showed that the risk of ascites/abscess in ABO non-Identical was higher than that in ABO-Id liver transplantation (P<0.05), and the risk of ascites/abscess after ABO-c liver transplantation was 2.246 times higher than that of ABO-Id liver transplantation. The primary biliary atresia were a risk factor for postoperative ascites/abscess. Conclusion: Enhanced postoperative management is critical for ABO-nonidentical (especially ABO-compatible) recipients, and those with biliary atresia to reduce complication risks.

ObjectiveTo observe the effect of modified Tianwang Buxindan （MTBD） on the skin of sleep-deprived （SD） mice and investigate its mechanism. MethodSixty 2-month-old female Kunming mice were randomly divided into a blank group， a model group， a vitamin C （VC， 0.08 g·kg^-1）， and MTBD low-， medium-， and high-dose groups （6.5， 12.5， 25 g·kg^-1）. Except for the blank group， the other groups were subjected to SD mouse model induction （using multiple platform water environment method for 18 hours of sleep deprivation daily from 15：00 to next day 9：00）， continuously for 14 days， and caffeine （CAF， 7.5 mg·kg^-1） was injected intraperitoneally from the 2nd week onwards， continuously for 7 days. While modeling， the blank group and the model group were administered with normal saline （0.01 mL·g^-1）， and the other groups received corresponding drugs for treatment. On the day of the experiment， general observations were recorded （such as body weight， spirit， fur， and skin）. After sampling， skin tissue pathological changes were observed under an optical microscope using hematoxylin-eosin （HE） and Masson staining methods. Skin thickness and skin moisture content were measured. Biochemical assay kits were used to detect skin hydroxyproline （HYP） content， skin and serum superoxide dismutase （SOD） activity， and malondialdehyde （MDA） content. Enzyme-linked immunosorbent assay （ELISA） was used to detect serum interleukin （IL）-6， tumor necrosis factor （TNF）-α， and IL-1β levels in mice. Western blot was used to detect skin tissue type Ⅰ collagen （ColⅠ）， type Ⅲ collagen （ColⅢ）， phosphatidylinositol 3-kinase （PI3K）， phosphorylated （p）-PI3K， protein kinase B （Akt）， p-Akt， nuclear factor E₂-related factor 2 （Nrf2）， heme oxygenase （HO）-1， and nuclear factor （NF）-κB protein expression. ResultCompared with the blank group， the model group showed varying degrees of changes. In general， signs of aging such as reduced body weight （P<0.01）， listlessness， dull fur color， and formation of wrinkles on the skin appeared. Tissue specimen testing revealed skin thinning， flattening of the dermoepidermal junction （DEJ）， and reduced collagen fibers under the optical microscope. Skin thickness and moisture content decreased， skin tissue HYP content significantly decreased （P<0.01）， skin and serum SOD activity significantly decreased （P<0.01）， and MDA content significantly increased （P<0.01）. Serum IL-6， TNF-α， and IL-1β levels significantly increased （P<0.01）. Skin ColⅠ， ColⅢ， p-PI3K/PI3K， p-Akt/Akt， Nrf2， and HO-1 protein expression significantly decreased （P<0.05， P<0.01）， and NF-κB expression increased （P<0.01）. Compared with the model group， the VC group and the MTBD low-dose group showed increased skin moisture content， HYP content， SOD activity， and ColⅠ， ColⅢ， p-PI3K/PI3K protein expression （P<0.05， P<0.01）， and decreased serum MDA content （P<0.05）. In addition， a decrease in serum IL-6 and IL-1β levels was detected in the MTBD low-dose group （P<0.05）， while the above indicators in the MTBD medium- and high-dose groups improved （P<0.05， P<0.01）. ConclusionSleep deprivation accelerates the aging process of the skin in SD model mice. MTBD can improve this phenomenon， exerting anti-inflammatory and antioxidant effects， and its mechanism of action may be related to the activation of the PI3K/Akt/Nrf2 signaling pathway.

Objective:To investigate the effect of modified citrus pectin (MCP) on the glucose metabolism of rabbit articular chondrocytes.Methods:The third generation (P3) rabbit knee chondrocytes were extracted and cultured with 0 μg/ml (MCP0, control group) and 500 μg/ml of MCP (MCP500) for 3 days. Chondrocytes (P2-P7)were cultured continuously, and each generation of chondrocytes was treated with MCP0 and MCP500 medium for 3 days. Chondrocytes were treated with interleukin-1β (IL-1β) for 1 day and then treated with MCP0 and MCP500 medium for 3 days, respectively. Chondrocytes were treated with 2-deoxy-glucose (2DG) for 1 day and then treated with MCP0 and MCP500 medium for 3 days, respectively. After three days of culture, the proliferation of chondrocytes was calculated by CCK-8. Glucose uptake activity and lactate production of chondrocytes were measured by glucose and lactate detection kits. The synthesis of type Ⅱ collagen (COL2A1) in sequential chondrocytes was investigated by immunofluorescence staining. The gene expression of COL2A1, proteoglycan ( ACAN), SOX9, hypoxia-inducible factor-1α ( HIF-1α), glucose transporter-1 ( Glut-1), pyruvate kinase M2 ( PKM2), lactate dehydrogenase-A ( LDHA) and glucose transporter-1 ( Glut-3) were further detected by RT-qPCR. Results:Compared with the control group, MCP treatment could increase the glucose uptake activity and lactate production of chondrocytes, and enhance the gene expression ability of HIF-1α, Glut-1, PKM2 and ACAN. Besides, MCP treatment could stimulate chondrocyte proliferation, maintain chondrocyte phenotype, increase lactate production, and upregulate the expression of COL2A1, ACAN, SOX9, HIF-1α, Glut-1, PKM2 and LDHA. After the treatment with IL-1β, MCP treatment could increase glucose uptake activity and upregulate the expression of COL2A1, ACAN, HIF-1α and Glut-1. After treatment with 2DG, MCP treatment could increase glucose uptake activity and upregulate the expression of SOX9, HIF-1α, PKM2 and Glut-3 genes. Conclusions:MCP can enhance the glucose uptake capacity of chondrocytes and increase the level of chondrocyte glycolytic metabolism.

Objective To investigate the changes of sex hormone levels in polycystic ovary syndrome(PCOS)in infertile population after the assisted reproductive technology treatment,and to provide an evidence for the choice of the treatment.Methods The medical data of patients admitted to the First Affiliated Hospital of Kunming Medical University from January 2016 to June 2021 were collected and divided into PCOS group(103)and non-PCOS group(589)according to whether they were diagnosed with PCOS,and the sex hormone changes of the two groups were compared.Results The patients in PCOS group were younger and had the higher BMI,more sinus follicles,higher AMH value,and lower total Gn usage.The number of LH/FSH>2 in PCOS group was higher than that in non-PCOS group(P<0.05).After the treatment,LH in both groups decreased,FSH,E2 and(P<0.05)increased;The difference of LH and E2 before and after the treatment in PCOS group was greater than that in non-PCOS group<0.05).Conclusion Compared with non-PCOS infertile patients,the changes of sex hormone indexes in PCOS infertile patients before and after the treatment were more obvious.In order to obtain the better clinical effect in patients with polycystic ovaries,it is recommended to pay attention to the changes of related sex hormone levels in the course of subsequent treatment,and choose a reasonable treatment plan.

Background The senescence of alveolar type II epithelial cells is an important driving factor for the progression of silicotic fibrosis, and the regulatory effects of oxamate on the senescence of alveolar type II epithelial cells is still unclear. Objective To explore whether lactate dehydrogenase inhibitor oxamate can alleviate silicotic fibrosis in mice by inhibiting senescence of alveolar type II epithelial cellsMethods This study was divided into two parts: in vivo experiments and in vitro experiments. In the first part, forty SPF C57BL/6J male mice were randomly divided into four groups with 10 in each group: control group, silicosis model group, low-dose oxamate treatment group, and high-dose oxamate treatment group. The silicotic mouse model was established by intratracheal instillation of 50 μL SiO₂ suspension (100 mg·mL⁻¹). The treatment models were prepared by intraperitoneal injection of 100 μL oxamate (225 mmol·L⁻¹ and 1125 mmol·L⁻¹). In the second part, induction of MLE-12 mouse alveolar type II epithelial cells was conducted with SiO₂. The in vitro experimental groups were ① SiO₂ induction groups: control group, 50 μg·mL⁻¹ SiO₂ group, 100 μg·mL⁻¹ SiO₂ group, and 200 μg·mL⁻¹ SiO₂ group, and ② oxamate treatment groups: control group, SiO₂ group (100 μg·mL⁻¹), low-dose oxamate (25 mmol·L⁻¹) treatment group, and high-dose oxamate (50 mmol·L⁻¹) treatment group. Pathological morphology of lung tissues was evaluated after hematoxylin-eosin (HE) staining; deposition of collagen in lung tissues was evaluated after sirius red staining; positive co-expression of prosurfactant protein C (Pro-SPC) and β-galactosidase was detected by immunofluorescence staining; positive expression of β-galactosidase in MLE-12 cells was detected by immunofluorescence staining. The protein expression levels of collagen type I (CoL I), fibronectin1 (FN1), hexokinase 2 (HK2), pyruvate kinase isozyme type M2 (PKM2), lactate dehydrogenase A (LDHA), p-ataxia telangiectasia and Rad3-related kinase (ATR), and cyclin-dependent kinase inhibitors p21, and p16 were detected by Western blotting. Results Compared with the control group, the protein expression levels of HK2, PKM2, LDHA, p-ATR, p21, and p16 were significantly upregulated in the silicosis model group and the SiO₂-induced MLE-12 cells (P＜0.05). The in vivo studies showed that, compared with the control group, the silicon nodule area, the collagen deposition area, the proportion of β-galactosidase positive cells, and the protein expression levels of CoL I, FN1, LDHA, p-ATR, p21, and p16 were significantly upregulated in the silicosis model group (P＜0.05). Compared with the silicosis model group, the oxamate treatment groups showed significant downregulation of the silicon nodule area, the collagen deposition area, the proportion of β-galactosidase positive cells, and the the CoL I, FN1, LDHA, p-ATR, p21, and p16 protein expression levels, and the high-dose oxamate treatment group showed a higher efficacy on these indicators than the low-dose oxamate treatment group (P＜0.05). The in vitro studies showed that, compared with the control group, the proportion of β-galactosidase positive cells and the protein expression levels of p-ATR, p21, and p16 were significantly upregulated in the SiO₂-induced group (P＜0.05). Compared with the SiO₂ group, the proportion of β-galactosidase positive cells and the LDHA, p-ATR, p21 and p16 protein expression levels were significantly downregulated in the oxamate treatment groups, and the high-dose oxamate treatment group showed a higher efficacy on these indicators than the low-dose oxamate treatment group (P＜0.05). Conclusion Lactate dehydrogenase inhibitor oxamate can alleviate silicotic fibrosis in mice by inhibiting the senescence of alveolar type II epithelial cells.

Objective:To explore the significance of laparoscopic virtual reality simulation training by analyzing the learning curve of laparoscopic cholecystectomy among young general surgeons who had participated in laparoscopic skills training at our hospital.Methods:Fifty young surgeons were divided into two groups, with the intervention group participating in virtual reality simulation training and the control group participating in traditional laparoscopic clinical training. After completion of the training, 30 laparoscopic cholecystectomies were performed under the supervision of highly qualified surgeons with extensive laparoscopic experience. CUSUM analysis was applied to plot the trainees' surgical learning curve based on the completion rate, surgical score and operative time. " x" is the number of surgical cases and " k" is the slope. The value of x when k=0 was calculated and the surgical learning curves and intraoperative scores of the 2 groups of trainees were compared. SPSS 23.00 was performed for t-test and Chi-square test. Results:The intervention and control groups crossed the surgical learning curve at x=19.24±0.39 and x=21.72±0.73 respectively, with significant differences ( P<0.01); the intervention and control groups scored (10.82±2.73) and (9.71±2.69) for gallbladder exposure ( t=4.61, P<0.01), (12.59±3.12) and (8.87±2.99) for gallbladder dissection triangle ( t=6.21, P<0.01), and (10.69±3.38) and (8.80±3.55) for gallbladder dissection ( t=3.10, P<0.01). Conclusions:Virtual reality simulation training can facilitate the translation of basic laparoscopic training skills into clinical skills and can promote the growth of young general surgeons.

Objective To investigate the effect of anti-Mullerian hormone(AMH)levels on the development potential of oocytes in patients with polycystic ovarian morphology(PCOM)complicated with infertility during in vitro fertilization-embryo transfer.Methods A total of 480 infertile patients who met the inclusion and exclusion criteria were selected(160 cases in control group,104 cases in PCOM group and 216 cases in PCOS group),AMH levels were compared among different groups.According to the serum AMH level(4.7ng/ml as normal value,＞4.7ng/ml as high value),both PCOM and PCOS patients were divided into normal AMH group and high AMH group.The differences of oocyte indexes and their correlation between different AMH levels in PCOM and PCOS patients were ana-lyzed.Results The basal androgen level in PCOS group was significantly higher than that in PCOM group(P＜0.01).The comparison of serum AMH value showed that the control group＜PCOM group＜PCOS group(P＜0.001).Laboratory indexes showed that the num-ber of mature oocytes,2PN,fertilization,D3 cleavage and total embryos in the high AMH group were significantly higher than those in the normal AMH group in PCOM and PCOS patients(P＜0.05).The AMH levels was positively correlated with the number of mature oo-cytes,2PN,fertilization,D3 cleavage and total embryos(P＜0.05).In the PCOS group,the number of dominant follicles,oocytes,high-quality embryos and available embryos in the high AMH group were significantly higher than those in the normal AMH group(P＜0.05),and the AMH levels was positively correlated with the number of dominant follicles,oocytes,high-quality embryos and available embryos(P＜0.05).However,there was no significant difference in the above indicators among different AMH levels in PCOM group(P＞0.05).Conclusion The serum AMH level of PCOM patients with infertility is higher than that of the control group,but lower than that of PCOS patients.PCOM patients with high AMH level can obtain better quality oocytes and more embryos,and increase the number of transplantation in patients with repeated transplantation failure,thereby improving the clinical pregnancy rate.

Objective:To explore the structural characteristics of intestinal microflora in children with non-alcoholic fatty liver disease（NAFLD）and the relationship between intestinal microflora and the occurrence as well as development of NAFLD in children.Methods:Fifteen children with NAFLD diagnosed at the First People's Hospital of Yunnan Province from January 2022 to December 2022 were selected as subjects，and 15 healthy children who received routine physical examinations at the outpatient clinic during the same period were randomly selected as healthy control group.The height，weight，waist circumference，blood pressure，blood biochemistry of all children were collected.At the same time，the fresh fecal samples of all children were collected，and the biological information of intestinal flora was analyzed by 16S rRNA sequencing.Results:In the NAFLD group，there were eight males and seven females，with an average age of（11.13±1.77）years.In healthy control group，there were seven males and eight females，with an average age of（9.73±2.25）years.There were no significant differences in sex，age，blood pressure between two groups.Compared with the healthy control group，the levels of body mass index，waist circumference，waist-to-height ratio，alanine aminotransferase，aspartate transaminase，gamma-glutamyl transpeptidase，total bilirubin，direct bilirubin，unconjugated bilirubin，low density lipoprotein cholesterol，uric acid and serum insulin significantly increased and high density lipoprotein cholesterol significantly decreased in NAFLD group（ P<0.05）.The results of species diversity analysis showed that chaol index and observed-species index in NAFLD group were significantly higher than those in healthy control group（ P<0.05）.Species diversity analysis showed that the species with increased abundance in NAFLD group included：Proteobacteria，Gammaproteobacteria，Enterobacteriaceae，Klebsiella，Escherichia-Shigella，Escherichia-Shigella-unclassified.Differential species with increased abundance in the healthy control group included：Bifidobacterium species，Bifidobacterium，Bifidobacteriaceae，Bifidobacteriales，Actinobacteria，Actinobacteriota，Bacteroidia，Bacteroidales，Streptococcus-thermophilus. Conclusion:There are metabolic abnormalities and obvious changes in the structure of intestinal flora in children with NAFLD.Exogenous supplementation of Bifidobacterium，Streptococcus thermophilus and Bacteroides may prevent the occurrence of NAFLD，delay the progression of disease and improve fat deposition in the liver.

Objective To study the levels of serum Periostin and interleukin(I1-)-18 in preterm infants with bronchopulmonary dysplasia(BPD),and to analyze their correlation with the severity of the disease and their predictive value for BPD.Methods A total of 62 preterm infants with BPD diagnosed and treated in the hospital from January 2019 to January 2022 were retrospectively selected as the BPD group,and 80 preterm in-fants without BPD during the same period were selected as the non-BPD group.According to the severity of BPD,the infants with BPD were divided into mild subgroup(22 cases),moderate subgroup(24 cases)and se-vere subgroup(16 cases).The serum levels of Periostin and IL-18 were detected by enzyme-linked immu-nosorbent assay.Pearson correlation analysis was used to analyze the correlation between the clinical parameters.Multivariate Logistic regression was used to analyze the influencing factors of BPD,and receiver operating characteristic(ROC)curve was used to analyze the predictive value of each indicator for BPD.Results Compared with the non-BPD group,the BPD group had a significantly higher proportion of infants with pulmonary surfactant(PS)use,neonatal respiratory distress syndrome,apnea,patent ductus arteriosus,and serum levels of Periostin and IL-18,as well as a significantly longer duration of mechanical ventilation,noninvasive respiratory support,and length of hospital stay.The lung function parameters[tidal volume per kilogram(VT/kg),ratio of time to peak tidal expiratory flow to time(TPTEF/TE),ratio of volume to peak tidal expiratory flow to volume(VPEF/VE),expiratory flow at 50％tidal volume(50％TEF),expiratory flow at 75％tidal volume(75％TEF)]and 1,5 min Apgar score of BPD group were lower than that of non-BPD group,and the differences were statistically significant(P＜0.05).The serum levels of Periostin and IL-18 in mild subgroup,moderate subgroup and severe subgroup were increased in turn.The levels of serum Periostin and IL-18 were negatively correlated with pulmonary function indexes(VT/kg,50％TEF,75％TEF,TPTEF/TE,VPEF/VE,P＜0.05).Serum Periostin,IL-18 and neonatal respiratory distress syndrome were independent risk factors for BPD(P＜0.05),and PS was a protective factor(P＜0.05).Serum Periostin,IL-18 and neonatal respiratory distress syndrome were independent risk factors for the severity of BPD(P＜0.05).The area under the curve(95％CI)of serum Periostin and IL-18 alone and in combination for predicting BPD were 0.841(0.814-0.899),0.863(0.820-0.897),0.922(0.878-0.949),respectively.The sensitivity and specificity of combined prediction were 0.902 and 0.825,respectively.The area under the curve of the combination of the two indica-tors for predicting BPD was greater than that of each index alone,and the difference was statistically signifi-cant(Z=5.357,4.894,P＜0.001).Conclusion The levels of serum Periostin and IL-18 are increased in in-fants with BPD,which are related to the severity of BPD and lung function.The combination of serum Perios-tin and IL-18 has a high predictive value for BPD.
