BACKGROUND:The preoperative planning of traditional X-ray films is often inaccurate,which can lead to some intraoperative and postoperative complications,increase the operation time and intraoperative blood loss,and to some extent affect the surgical outcome of total hip arthroplasty. OBJECTIVE:To investigate the accuracy and effectiveness of artificial intelligence preoperative planning in total hip arthroplasty. METHODS:Sixty patients who underwent primary total hip arthroplasty on the affected side were selected.30 of them used artificial intelligence 3D preoperative planning(trial group)and 30 used conventional X-ray film 2D preoperative planning(control group),and there were no statistically significant differences between the two groups in terms of gender,age,condition and other general data(P>0.05).The actual intraoperative prosthesis placement and preoperative planning prosthesis matching,intraoperative operation time,intraoperative blood loss,bilateral femoral eccentric distance difference,bilateral joint eccentric distance difference and bilateral lower limb length difference,and Harris score at 3 months after operation were compared between the two groups,and the accuracy and application effect of the two preoperative plans were analyzed. RESULTS AND CONCLUSION:(1)Patients in both groups were followed up for 4-6 months postoperatively.One patient in the control group had a posterior dislocation of the prosthesis at 5 days postoperatively,which recovered after performing manual repositioning without re-dislodgement.The rest of the patients did not have postoperative complications or postoperative death.(2)Complete matching rate of the prosthesis on the acetabular side and femoral side was significantly better in the trial group than that in the control group(P<0.05).(3)Operation time and intraoperative blood loss were significantly less in the trial group than those in the control group(P<0.05).(4)The difference in bilateral lower limb length between the two groups was statistically significant(P<0.05),and the difference in bilateral femoral eccentric distance and bilateral joint eccentric distance was not statistically significant(P>0.05).(5)Harris score of patients in the trial group was significantly higher than that in the control group 3 months after operation(P<0.05).(6)These results confirm that compared with traditional film planning,artificial intelligence preoperative planning can predict the prosthesis type more accurately,shorten the operation time,reduce intraoperative blood loss,diminish the occurrence of postoperative bilateral lower limb inequality,and accelerate postoperative recovery.

Objective:To investigate the incidence characteristics and influencing factors of non-alcoholic fatty liver disease (NAFLD) in rural Uyghur ethnic group residents in Xinjiang Production and Construction Corps and to provide scientific evidence for early identification and prevention of NAFLD for residents.Methods:A total of 10 158 participants were included from the Xinjiang Uygur ethnic group population cohort. A prospective cohort study and Cox proportional hazards regression model analysis were used to explore the influencing factors and clustering of NAFLD, and the dose-response relationship between related biochemical indicators and the risk of NAFLD was studied using a restricted cubic spline.Results:The cumulative incidence rate of NAFLD was 6.9%, and the incidence density of NAFLD was 12.06/1 000 person-years. The incidence density of NAFLD in females was higher than in males (14.72/1 000 person-years vs. 9.17/1 000 person-years, P<0.001). The incidence density of NAFLD gradually increased with age in the total population, both men and women (all P<0.001). In the general population, an education level of junior high school or above was a protective factor for NAFLD, while older age, divorce, widowhood, overweight, obesity, hypertension, increased glomerular filtration rate, decreased HDL-C, increased LDL-C, and increased ALT were risk factors for NAFLD. Estimated glomerular filtration rate (eGFR), HDL-C, LDL-C, and ALT were non-linearly correlated with the incidence of NAFLD, and there was a significant dose-response relationship between them. Only 19.1% of residents had no NAFLD risk factors; over 80.9% had ≥1 NAFLD risk factors. The risk of NAFLD increased with the number of risk factors. Conclusions:The incidence of NAFLD in rural Uygur ethnic group residents in Xinjiang Production and Construction Corps was relatively low, but most residents had one or more risk factors for NAFLD. Prevention and control of NAFLD in this population cannot be ignored. In addition, people of older age, divorced or widowed, low education level, overweight or obese, hypertension, and abnormal eGFR, HDL-C, LDL-C, and ALT were the high-risk groups of NAFLD that need to be paid attention to in this population.

Objective To investigate the effect of progesterone receptor membrane component 1(PGRMC1)mediated autophagy on the sensitivity of liver cancer cells to 125I particles irradiation.Methods Hepatoma cell lines Huh7 and LM3 were exposed to different doses(0,2,4,6 and 8 Gy)of 125I particles,and cell autophagy was observed by transmission electron microscopy(TEM).Then,autophagy inhibitor chloroquine(CQ),agonist rapamycin(Rapa),and PGRMC1 inhibitor AG-205 were used respectively to verify that PGRMC1-mediated autophagy plays a key role in the sensitivity of hepatocellular carcinoma cells to 125I particle irradiation.Cell proliferation,colony formation and apoptosis were detected by CCK-8 assay,clonal formation test and flow cytometry,respectively.The expression levels of PGRMC1,microtubule-associated protein light chain 3-Ⅰ(LC3-Ⅰ),LC3-Ⅱ and p62 were detected by Western blotting.Results Different doses of 125I particles irradiation significantly decreased the proliferation and clonogenesis of Huh7 and LM3 cells(P＜0.05),and increased the apoptotic cells(P＜0.01),in a dose-dependent manner.Compared with the 0 Gy group,the ratio of LC3-Ⅱ/LC3-Ⅰ in Huh7 and LM3 cells was obviously increased,and the expression of p62 was significantly down-regulated in the 6 Gy group.The proliferation capacity and clonal formation ability of Huh7 and LM3 cells were decreased significantly,and their apoptotic cells were increased notably in the 6 Gy+CQ group than the 6 Gy group,while the above results were on the contrary in the 6 Gy+Rapa group.The 6 Gy+AG205 group had notably decreased LC3-Ⅱ/LC3-Ⅰ ratio in the Huh7 and LM3 cells,up-regulated p62 expression,reduced cell proliferation capacity and clone formation ability,and enhanced cell apoptosis when compared with the 6 Gy group,and the above results of the 6 Gy+PGRMC1 group were opposite.Conclusion Increment of PGRMC1 induced by 125I irradiation can promote autophagy,increase the proliferation and clonogenesis,and reduce the apoptosis in hepatocellular carcinoma cells.

Background/Aims: The shortage of donor liver hinders the development of liver transplantation. This study aimed to clarify the poor outcomes of functionally marginal liver grafts (FMLs) and provide evidence for the improvement of ischemia-free liver transplantation (IFLT) after FML transplantation. Methods: Propensity score matching was used to control for confounding factors. The outcomes of the control group and FML group were compared to demonstrate the negative impact of FMLs on liver transplantation patients. We compared the clinical improvements of the different surgical types. To elucidate the underlying mechanism, we conducted bioinformatic analysis based on transcriptome and single-cell profiles. Results: FMLs had a significantly greater hazard ratio (HR: 1.969, P=0.018) than did other marginal livers. A worse 90-day survival (Mortality: 12.3% vs. 5.0%, P=0.007) was observed in patients who underwent FML transplantation. Patients who received FMLs had a significant improvement in overall survival after IFLT (Mortality: 10.4% vs 31.3%, P=0.006). Pyroptosis and inflammation were inhibited in patients who underwent IFLT. The infiltration of natural killer cells was lower in liver grafts from these patients. Bulk transcriptome profiles revealed a positive relationship between IL-32 and Caspase 1 (R=0.73, P=0.01) and between IL-32 and Gasdermin D (R=0.84, P=0.0012). Conclusions FML is a more important negative prognostic parameter than other marginal liver parameters. IFLT might ameliorate liver injury in FMLs by inhibiting the infiltration of NK cells, consequently leading to the abortion of IL-32, which drives pyroptosis in monocytes and macrophages.

OBJECTIVE: To depict the cell landscape and molecular biological characteristics of human intrauterine adhesion (IUA) so as to better understand its immune microenvironment and provide new inspirations for clinical treatment. METHODS: Four patients with IUA who underwent hysteroscopic treatment at Dongguan Maternal and Child Health Care Hospital from February 2022 to April 2022 were selected as the study subjects. Hysteroscopy was used to collect the tissues of IUA, which were graded based on the patient's medical history, menstrual history and status of IUA. Library construction, sequencing, single cell data comparison and gene expression matrix construction were carried out in strict accordance with the single cell RNA sequencing process. Thereafter, the UMAP dimension reduction analysis of cell population and genetic analysis were carried out based on the cell types. RESULTS: A total of 27 511 cell transcripts were obtained from four moderately graded IUA tissue samples and assigned to six cell lineages including T cells, mononuclear phagocytes, epithelial cells, fibroblasts, endothelial cells and erythrocytes. Compared with normal uterine tissue cells, the four samples showed different cell distribution, and the proportions of mononuclear phagocytes and T cells in sample IUA0202204 were significantly increased, suggesting a strong cellular immune response. CONCLUSION The cell diversity and heterogeneity of moderate IUA tissues have been described. Each cell subgroup has unique molecular characteristics, which may provide new clues for further study of the pathogenesis of IUA and heterogeneity among the patients.

Objective:To analyze whether triglyceride-glucose (TyG) index is associated with increased risk of cardiovascular diseases (CVD) and the value of TyG index in predicting CVD risk among Kazakh and Uighur population of Xinjiang.Methods:In this study, 5 375 Kazakh and Uygur people of Xinyuan county and Jiashi county were selected as the research objects. Subjects were divided into four groups based on the quartile of the TyG index level. Cox regression model was used to analyze the association between TyG index with the risk of CVD. The dose-response relationship between TyG index and CVD risk was described by restricted cubic splines. The area under the receiver operating characteristic curve, net reclassification improvement (NRI), and integrated discrimination improvement (IDI) were used to estimate the value of TyG index for predicting CVD. Mediating effect analysis was conducted to analyze the mediating effect of TyG index in the association between body mass index and CVD.Results:The age of subjects was 41.06（30.11，53.00）years old, with 46.30%（2 489/5 375）was male. After multivariate adjustment, there was an increasing trend between the risk of CVD and the higher TyG index Ptrend<0.001, compared with subjects of TyG index in Q1, the HR (95% CI) of Q2, Q3, and Q4 groups was 1.53, 1.23 and 1.73, respectively. Restricted cubic splines showed that TyG index was the linearly associated with the risk of CVD. TyG index could improve the prediction ability of Framingham model for the risk of CVD (NRI=0.106, P=0.010; IDI=0.003, P=0.030). The mediating effect analysis showed that in the relationship between body mass index and CVD, the TyG index had a mediating effect ( P<0.001), and the ratio of mediating effect was 12.69%. Conclusion:TyG index is an independent predictor of CVD risk among kazakh and Uygur population in Xinjiang and has a good predictive value for the risk of CVD.

Objective:To evaluate the effect of intrathecal insulin-like growth factor-1 (IGF-1) on chemotherapy-induced neuropathic pain (NP) in mice.Methods:Forty clean-grade healthy male C57 mice, aged 7-9 weeks, weighing 22-24 g, were divided into 4 groups ( n=10 each) using a random number table method: control group (group C), chemotherapy-induced NP group (group CIPN), low-dose IGF-1 group (group I1) and high-dose IGF-1 group (group I2). In CIPN, I1 and I2 groups, oxaliplatin 5 mg/kg was intraperitoneally injected for 5 consecutive days to establish chemotherapy-induced NP model.Normal saline 0.2 ml was given in group C. After measurement of the pain threshold at 10 days after establishment of the model, IGF-1 0.5 and 1.0 μg were intrathecally injected in group I1 and group I2, respectively.Normal saline 5 μl was intrathecally injected in C and CINP groups.Mechanical withdrawal threshold (MWT) was measured at 3, 5, 8, 10, 11, 13 and 15 days after establishment of the model.After measurement of the pain threshold at 15 days after establishment of the model, the expression of spinal IGF-1, IGF-1receptor (IGF-1R), interleukin (IL)-17A, IL-1β and tumor necrosis factor (TNF)-α was detected, and IGF-1 positive cells were counted using immunofluorescence. Results:Compared with group C, MWT was significantly decreased, the expression of spinal IGF-1 was down-regulated, the count of IGF-1 positive cells was decreased, and expression of IL-17A, IL-1β and TNF-α was up-regulated at 3-25 days after establishment of the model in CINP, I1 and I2 groups ( P<0.05). Compared with group CIPN, MWT was significantly increased at 15 days after establishment of the model in group I1, and MWT was increased, the expression of spinal IGF-1 was up-regulated, the count of IGF-1 positive cells was increased, and expression of IL-17A, IL-1β and TNF-α was down-regulated at 13 and 15 days after establishment of the model in group I2 ( P<0.05). Compared with group I1, the count of IGF-1 positive cells in spinal dorsal horn was increased in group I2 ( P<0.05). There was no significant difference in the expression of spinal IGF-1R among the 4 groups ( P>0.05). Conclusion:Intrathecal IGF-1 can alleviate chemotherapy-induced NP, and the mechanism may be related to inhibiting the inflammatory responses in spinal cord of mice.

Objective: To construct and confirm a predictive model for the risks of cardiovascular diseases (CVD) with metabolic syndrome (MS) and its factors in Xinjiang Kazakh population. Methods: A total of 2 286 Kazakh individuals were followed for 5 years from 2010 to 2012 as baseline survey. They were recruited in Xinyuan county, Yili city, Xinjiang. CVD cases were identified via medical records of the local hospitals in 2013, 2016 and 2017, respectively. Factor analysis was performed on 706 MS patients at baseline, and main factors, age, and sex were extracted from 18 medical examination indexs to construct a predictive model of CVD risk. After excluding the subjects with CVD at baseline and incomplete data, 2007 were used as internal validation, and 219 Kazakhs in Halabra Township were used as external validation. Logistic regression discriminations were used for internal validation and external validation, as well as to calculate the probability of CVD for each participant and receiver operating characteristic curves. Results: The prevalence of MS in Kazakh was 30.88%. Seven main factors were extracted from the Kazakh MS population, namely obesity factor, blood lipid and blood glucose factor, liver function factor, blood lipid factor, renal metabolic factor, blood pressure factor, and liver enzyme factor. The area under the curve (AUC) for predicting CVD in the internal validation was 0.773 (95%CI 0.754-0.792). In the external validation, the AUC for predicting CVD was 0.858 (95%CI 0.805-0.901). Conclusions The CVD risk prediction model constructed by 7 main factors extracted from Kazakh MS patients has high validation efficiency and can be used for risk assessment of CVD in Xinjiang Kazakh population.

Objective:To compare anti-mullerian hormone (AMH) , sex hormone and inhibitor B (Inhibin B, INH-B) levels in children with different karyotypes, ages, and gender disorders of sex developmemt (DSD).Methods:A total of 101 patients with suspected gonadal dysplasia in children who underwent serological examination at the Children′s Hospital of Hunan Province from January 2019 to June 2019 were finally diagnosed by pathological biopsy. With reference to previous studies of the same type, the 101 patients included in this study were divided into 4 levels (<1 year old, 1-2 years old, 2-4 years old, >4 years old), and the social gender was divided into two levels: male and female. At the same time, 89 cases of normal gonadal development children without endocrine abnormality were selected as control. Serum levels of AMH, INH-B, luteinizing hormone (LH), follicle stimulating hormone (FSH), estradiol (E2), prolactin (PRL) and testosterone (T) were measured by chemiluminescence method.Results:Among the 101 cases, 62 were male and 39 were female; aged 23 days to 12 years, with a median age of 3.3 years; karyotype: 52 cases were 46, XX; 21 cases were 46, XY; 12 cases were 45, X; 7 cases were 46X, del (Xq); 5 cases were 46X, i (Xq); 2 cases were 45X, inv9; 2 cases were 45X / 46XX. There were 65 cases of partial gonadal dysplasia, 25 cases of disappearing testicular syndrome, and 11 cases of mixed gonadal dysplasia. One patient had a family history of infertility. Among the causes of children′s consultation, the most common were abnormal appearance of the external genitalia (54 cases, 53.47%), followed by small penile development and / or scrotal emptiness (25 cases, 24.75%). Other reasons included primary amenorrhea, double lateral groin mass, hypertension, clitoral hypertrophy, and labia minora adhesions. The levels of serum AMH, INH-B, and T in the gonadal dysplasia group were significantly higher than those in the normal gonadal development group, while the levels of LH, FSH, E2, and PRL were significantly lower than those in the normal gonadal development group ( P<0.05). The INH-B level of children with gonadal dysplasia in different age groups was statistically significant ( P<0.05), in which the INH-B level was the highest in <1-year-old children with gonadal dysplasia, and the lowest in 2-4-year-old children with gonadal dysplasia; the LH, FSH, E2, PRL, T levels of 46, XX and other karyotypes were statistically significant ( P<0.05); Compared with other age groups, the levels of LH, FSH, E2, and PRL were relatively higher in >4 year-old children with gonadal dysplasia, while the level of T was relatively lower; There were significant differences in E2, PRL and T levels in children with gonadal dysplasia in different age groups of 46, XY karyotype ( P<0.05). Compared with other age groups, E2, PRL and T levels of children with gonadal dysplasia >4 year-old old were relatively higher and T levels were relatively lower. The levels of AMH, LH, FSH, E2 and PRL in boys with glandular dysplasia were lower than those in girls ( P<0.05), while the levels of INH-B and T were higher in boys than those in girls ( P<0.05). Conclusions:The levels of anti-mullerian hormones, inhibin B, and sex hormones in children with gonadal dysplasia are different from the normal population, and may be related to the age, chromosome karyotype, and gender distribution of the child, but there are some confounding factors (such as etiology, treatment Scheme), so more samples are needed to verify it.
