Oral diseases concern almost every individual and are a serious health risk to the popula-tion.The restorative treatment of tooth and jaw defects is an important means to achieve oral function and support the appearance of the contour.Based on the principle of"learning from the nature",Deng Xu-liang's group of Peking University School and Hospital of Stomatology has proposed a new concept of"microstructural biomimetic design and tissue adaptation of tooth/jaw materials"to address the worldwide problems of difficulty in treating dentine hypersensitivity,poor prognosis of restoration of tooth defects,and vertical bone augmentation of alveolar bone after tooth loss.The group has broken through the bottle-neck of multi-stage biomimetic technology from the design of microscopic features to the enhancement of macroscopic effects,and invented key technologies such as crystalline/amorphous multi-level assembly,ion-transportation blocking,and multi-physical properties of the micro-environment reconstruction,etc.The group also pioneered the cationic-hydrogel desensitizer,digital stump and core integrated restora-tions,and developed new crown and bridge restorative materials,gradient functionalisation guided tissue regeneration membrane,and electrically responsive alveolar bone augmentation restorative membranes,etc.These products have established new clinical strategies for tooth/jaw defect repair and achieved inno-vative results.In conclusion,the research results of our group have strongly supported the theoretical im-provement of stomatology,developed the technical system of oral hard tissue restoration,innovated the clinical treatment strategy,and led the progress of the stomatology industry.

Objective:To analyze the status quo of type D personality, intolerance of uncertainty and family support in first-episode stroke patients, and to explore the mediating role of family support between type D personality and intolerance of uncertainty in first-episode stroke patients, in order to provide reference for formulating relevant clinical intervention measures to promote the physical and mental health of first-episode stroke patients.Methods:This study was a cross-sectional investigation. A total of 300 patients with acute first-episode stroke who met the inclusion and exclusion criteria in the Department of Neurology of the General Hospital of Ningxia Medical University and the First People′s Hospital of Yinchuan from May 2023 to September 2023 were selected as the study objects by convenience sampling method. The general data questionnaire, Type D personality Scale-14, Family Caring Index Scale and the Intolerance of Uncertainty Scale were used to investigate them. Pearson correlation analysis was used to test the correlation between variables, and SPSS plug-in PROCESS 3.5 was used to test the mediation effect.Results:Finally, 300 questionnaires were effectively collected, including 228 males and 72 females. Patients aged ≥ 60 years old were the majority, accounting for 49.3% (148/300). The detection rate of type D personality in the first stroke patients was 37.3% (112/300), and the total score of Type D personality inventory, family support and intolerance of uncertainty of type D personality in the first stroke patients were (22.16 ± 9.95), (6.40 ± 2.23), (27.82 ± 7.93) points. The correlation analysis results showed that the intolerance of uncertainty of type D personality in the first stroke patients was positively correlated with type D personality scores ( r=0.675, P<0.001). There was a negative correlation with family support score ( r=-0.644, P<0.001). The results of mediating effect analysis showed that family support played a partial mediating role in the relationship between type D personality and intolerability of uncertainty in first-stroke patients, and the mediating effect accounted for 34.94% of the total effect. Conclusions:The mediating role of family support between type D personality and intolerability of uncertainty in first-stroke patients is established. In the future, the level of family support of patients can be continuously improved to reduce their intolerability of uncertainty, so as to promote the physical and mental health of patients and improve their quality of life.

Vigabatrin-associated brain abnormalities on magnetic resonance imaging (VABAM) is a relatively rare side effect of vigabatrin, most of which are asymptomatic. However, there will be extremely rare cases with hyperkinetic disorders, myoclonus, tremor, and acute encephalopathy under certain circumstances. VABAM is often underappreciated by physicians and its accurate incidence remains unclear. A female infant who was diagnosed with infantile spasms and required adrenocorticotropic hormone therapy accompanied by various antiseizure medicines was reported. Unfortunately, she became lethargic and her spasm deteriorated gradually after vigabatrin exposure. Her brain magnetic resonance imaging revealed abnormal signals bilaterally in the dorsal midbrain, thalamus, and rostral part of the pallidum. She had a seizure amelioration and became lively as a result of vigabatrin withdrawal. In the meanwhile, magnetic resonance imaging returned to normal. Attempts were made to discover the risk factors of VABAM and potential pathogenesis. Further understanding of the disease should contribute to decreasing misdiagnosis and making precise decisions.

Objective:To explore the potential categories of resourcefulness in primary caregivers of stroke patients and analyze the differences in the characteristics of different types of caregivers, so as to provide basis for clinical construction of effective intervention plans.Methods:The 308 primary caregivers of stroke patients who met the research standards in the Department of Neurology of General Hospital of Ningxia Medical University, People′s Hospital of Ningxia Hui Autonomous Region, the First People′s Hospital of Yinchuan from December 2020 to August 2021 were selected as the research objects by convenient sampling method.The general information questionnaire, Resourcefulness Scale and Social Support Revalued Scale were used for cross-sectional investigation.Results:The resourcefulness of the primary caregivers of stroke patients were divided into 2 potential categories: low resourcefulness group (62.7%, 193/308) and high resourcefulness group (37.3%, 115/308). Uni-variate analysis showed that there were differences between potential categories: age and education level of stroke patients, whether there was long-term medication history, number of other chronic diseases, had there been any complications due to illness, age, education level and occupation of caregivers, average daily care duration, family relations, and social support ( χ2 values were -3.34 - 23.62, all P<0.05). Logistic regression analysis showed that social support and education level of caregivers were the influencing factors of caregiver resourcefulness ( P<0.05). Conclusions:The resourcefulness in the primary caregivers of stroke patients has certain characteristics. Clinically, targeted intervention measures should be formulated according to the different types of caregiver resourcefulness characteristics of caregivers and their influencing factors to improve the caregiver resourcefulness of stroke patients.

Objective:To investigate the epidemiological characteristics, diagnosis, treat-ment and prognosis of gallbladder cancer in China from 2010 to 2017.Methods:The single disease retrospective registration cohort study was conducted. Based on the concept of the real world study, the clinicopathological data, from multicenter retrospective clinical data database of gallbladder cancer of Chinese Research Group of Gallbladder Cancer (CRGGC), of 6 159 patients with gallbladder cancer who were admitted to 42 hospitals from January 2010 to December 2017 were collected. Observation indicators: (1) case resources; (2) age and sex distribution; (3) diagnosis; (4) surgical treatment and prognosis; (5) multimodality therapy and prognosis. The follow-up data of the 42 hospitals were collected and analyzed by the CRGGC. The main outcome indicator was the overall survival time from date of operation for surgical patients or date of diagnosis for non-surgical patients to the end of outcome event or the last follow-up. Measurement data with normal distribu-tion were represented as Mean±SD, and comparison between groups was conducted using the t test. Measurement data with skewed distribution were represented as M( Q1, Q3) or M(range), and com-parison between groups was conducted using the U test. Count data were described as absolute numbers or percentages, and comparison between groups was conducted using the chi-square test. Univariate analysis was performed using the Logistic forced regression model, and variables with P<0.1 in the univariate analysis were included for multivariate analysis. Multivariate analysis was performed using the Logistic stepwise regression model. The life table method was used to calculate survival rates and the Kaplan-Meier method was used to draw survival curves. Log-rank test was used for survival analysis. Results:(1) Case resources: of the 42 hospitals, there were 35 class A of tertiary hospitals and 7 class B of tertiary hospitals, 16 hospitals with high admission of gallbladder cancer and 26 hospitals with low admission of gallbladder cancer, respectively. Geographical distribution of the 42 hospitals: there were 9 hospitals in central China, 5 hospitals in northeast China, 22 hospitals in eastern China and 6 hospitals in western China. Geographical distribution of the 6 159 patients: there were 2 154 cases(34.973%) from central China, 705 cases(11.447%) from northeast China, 1 969 cases(31.969%) from eastern China and 1 331 cases(21.611%) from western China. The total average number of cases undergoing diagnosis and treatment in hospitals of the 6 159 patients was 18.3±4.5 per year, in which the average number of cases undergoing diagnosis and treatment in hospitals of 4 974 patients(80.760%) from hospitals with high admission of gallbladder cancer was 38.8±8.9 per year and the average number of cases undergoing diagnosis and treatment in hospitals of 1 185 patients(19.240%) from hospitals with low admission of gallbladder cancer was 5.7±1.9 per year. (2) Age and sex distribution: the age of 6 159 patients diagnosed as gallbladder cancer was 64(56,71) years, in which the age of 2 247 male patients(36.483%) diagnosed as gallbladder cancer was 64(58,71)years and the age of 3 912 female patients(63.517%) diagnosed as gallbladder cancer was 63(55,71)years. The sex ratio of female to male was 1.74:1. Of 6 159 patients, 3 886 cases(63.095%) were diagnosed as gallbladder cancer at 56 to 75 years old. There was a significant difference on age at diagnosis between male and female patients ( Z=-3.99, P<0.001). (3) Diagnosis: of 6 159 patients, 2 503 cases(40.640%) were initially diagnosed as gallbladder cancer and 3 656 cases(59.360%) were initially diagnosed as non-gallbladder cancer. There were 2 110 patients(34.259%) not undergoing surgical treatment, of which 200 cases(9.479%) were initially diagnosed as gallbladder cancer and 1 910 cases(90.521%) were initially diagnosed as non-gallbladder cancer. There were 4 049 patients(65.741%) undergoing surgical treatment, of which 2 303 cases(56.878%) were initially diagnosed as gallbladder cancer and 1 746 cases(43.122%) were initial diagnosed as non-gallbladder cancer. Of the 1 746 patients who were initially diagnosed as non-gallbladder cancer, there were 774 cases(19.116%) diagnosed as gallbladder cancer during operation and 972 cases(24.006%) diagnosed as gallbladder cancer after operation. Of 6 159 patients, there were 2 521 cases(40.932%), 2 335 cases(37.912%) and 1 114 cases(18.087%) undergoing ultrasound, computed tomography (CT) or magnetic resonance imaging (MRI) examination before initial diagnosis, respec-tively, and there were 3 259 cases(52.914%), 3 172 cases(51.502%) and 4 016 cases(65.205%) undergoing serum carcinoembryonic antigen, CA19-9 or CA125 examination before initially diagnosis, respectively. One patient may underwent multiple examinations. Results of univariate analysis showed that geographical distribution of hospitals (eastern China or western China), age ≥72 years, gallbladder cancer annual admission of hospitals, whether undergoing ultrasound, CT, MRI, serum carcinoembryonic antigen, CA19-9 or CA125 examination before initially diagnosis were related factors influencing initial diagnosis of gallbladder cancer patients ( odds ratio=1.45, 1.98, 0.69, 0.68, 2.43, 0.41, 1.63, 0.41, 0.39, 0.42, 95% confidence interval as 1.21-1.74, 1.64-2.40, 0.59-0.80, 0.60-0.78, 2.19-2.70, 0.37-0.45, 1.43-1.86, 0.37-0.45, 0.35-0.43, 0.38-0.47, P<0.05). Results of multivariate analysis showed that geographical distribution of hospitals (eastern China or western China), sex, age ≥72 years, gallbladder cancer annual admission of hospitals and cases undergoing ultrasound, CT, serum CA19-9 examination before initially diagnosis were indepen-dent influencing factors influencing initial diagnosis of gallbladder cancer patients ( odds ratio=1.36, 1.42, 0.89, 0.67, 1.85, 1.56, 1.57, 0.39, 95% confidence interval as 1.13-1.64, 1.16-1.73, 0.79-0.99, 0.57-0.78, 1.60-2.14, 1.38-1.77, 1.38-1.79, 0.35-0.43, P<0.05). (4) Surgical treatment and prognosis. Of the 4 049 patients undergoing surgical treatment, there were 2 447 cases(60.435%) with complete pathological staging data and follow-up data. Cases with pathological staging as stage 0, stage Ⅰ, stage Ⅱ, stage Ⅲa, stage Ⅲb, stage Ⅳa and stage Ⅳb were 85(3.474%), 201(8.214%), 71(2.902%), 890(36.371%), 382(15.611%), 33(1.348%) and 785(32.080%), respectively. The median follow-up time and median postoperative overall survival time of the 2 447 cases were 55.75 months (95% confidence interval as 52.78-58.35) and 23.46 months (95% confidence interval as 21.23-25.71), respectively. There was a significant difference in the overall survival between cases with pathological staging as stage 0, stage Ⅰ, stage Ⅱ, stage Ⅲa, stage Ⅲb, stage Ⅳa and stage Ⅳb ( χ2=512.47, P<0.001). Of the 4 049 patients undergoing surgical treatment, there were 2 988 cases(73.796%) with resectable tumor, 177 cases(4.371%) with unresectable tumor and 884 cases(21.833%) with tumor unassessable for resectabi-lity. Of the 2 988 cases with resectable tumor, there were 2 036 cases(68.139%) undergoing radical resection, 504 cases(16.867%) undergoing non-radical resection and 448 cases(14.994%) with operation unassessable for curative effect. Of the 2 447 cases with complete pathological staging data and follow-up data who underwent surgical treatment, there were 53 cases(2.166%) with unresectable tumor, 300 cases(12.260%) with resectable tumor and receiving non-radical resection, 1 441 cases(58.888%) with resectable tumor and receiving radical resection, 653 cases(26.686%) with resectable tumor and receiving operation unassessable for curative effect. There were 733 cases not undergoing surgical treatment with complete pathological staging data and follow-up data. There was a significant difference in the overall survival between cases not undergoing surgical treatment, cases undergoing surgical treatment for unresectable tumor, cases undergoing non-radical resection for resectable tumor and cases undergoing radical resection for resectable tumor ( χ2=121.04, P<0.001). (5) Multimodality therapy and prognosis: of 6 159 patients, there were 541 cases(8.784%) under-going postoperative adjuvant chemotherapy and advanced chemotherapy, 76 cases(1.234%) under-going radiotherapy. There were 1 170 advanced gallbladder cancer (pathological staging ≥stage Ⅲa) patients undergoing radical resection, including 126 cases(10.769%) with post-operative adjuvant chemotherapy and 1 044 cases(89.231%) without postoperative adjuvant chemo-therapy. There was no significant difference in the overall survival between cases with post-operative adjuvant chemotherapy and cases without postoperative adjuvant chemotherapy ( χ2=0.23, P=0.629). There were 658 patients with pathological staging as stage Ⅲa who underwent radical resection, including 66 cases(10.030%) with postoperative adjuvant chemotherapy and 592 cases(89.970%) without postoperative adjuvant chemotherapy. There was no significant difference in the overall survival between cases with postoperative adjuvant chemotherapy and cases without postoperative adjuvant chemotherapy ( χ2=0.05, P=0.817). There were 512 patients with pathological staging ≥stage Ⅲb who underwent radical resection, including 60 cases(11.719%) with postoperative adjuvant chemotherapy and 452 cases(88.281%) without postoperative adjuvant chemotherapy. There was no significant difference in the overall survival between cases with postoperative adjuvant chemo-therapy and cases without post-operative adjuvant chemo-therapy ( χ2=1.50, P=0.220). Conclusions:There are more women than men with gallbladder cancer in China and more than half of patients are diagnosed at the age of 56 to 75 years. Cases undergoing ultrasound, CT, serum CA19-9 examination before initial diagnosis are independent influencing factors influencing initial diagnosis of gallbladder cancer patients. Preoperative resectability evaluation can improve the therapy strategy and patient prognosis. Adjuvant chemotherapy for gallbladder cancer is not standardized and in low proportion in China.

Objective:To investigate and analyze the correlation between blood pressure and serum creatinine (Scr) and glomerular filtration rate (GFR).Methods:This research was a cross-sectional study, a total of 46792 people over 20 years old with relatively complete data in the health management center of the First Affiliated Hospital of Xinjiang Medical University from January to December 2018 were included as the research subjects, and baseline data of these study subjects were obtained by on-site questionnaire, collection of blood pressure, creatinine and other physiological and biochemical indicators. The subjects were divided into 20-64 years old group and ≥65 years group according to their age; being treated as the continuous variables (systolic blood pressure, diastolic blood pressure, five categories), their blood pressure indicators were analyzed. The F test, t test, χ2 test and logistic regression model were used to analyze the baseline characteristics of Scr level and GFR, as well as the correlation between blood pressure and Scr and GFR. Results:(1) The average Scr level was (72.89±16.84) μmol/L in the study population aged 20-93. The average GFR was (102.17±17.01) ml·min -1·(1.73 m 2) -1. The average Scr of men was higher than that of women, the average GFR of men was lower than that of women (all P<0.001). (2) Among the subjects above, there were 514 cases (1.10%) with abnormal Scr level and 657 cases (1.40%) with abnormal GFR, the incidence of abnormal Scr and GFR was higher in men, subjects with age ≥65 years old, or diabetes, or hypertension (all P<0.05). (3) There were significant differences in Scr level and GFR in subjects with different gender, age, blood pressure and body mass index (BMI) (all P<0.05). (4) With the increase of blood pressure, among the crowd of 24-64 years old, the relative risk of abnormal Scr and GFR in the group with baseline blood pressure ≥180/110 mmHg was 8.434 and 5.168 times higher than that in the group with baseline blood pressure<120/80 mmHg, respectively, after adjusting variables such as sex, age, nationality, BMI, hypertension, diabetes. However, among the crowd of ≥65 years old, only the relative risk in the group with baseline blood pressure of 160-179/100-109 mmHg was statistically significant compared with<120/80 mmHg. Conclusion:The blood pressure is bound up with Scr and GFR in the crowd of 24-64 years old.

BACKGROUND: Perivascular cells have been shown to be the precursor cells of mesenchymal stem cells, which regulate the behavior of hematopoietic stem cells and support hematopoiesis through cell-to-cell contact or paracrine effects. Hematopoietic support of human skeletal muscle-derived pericytes/perivascular cells (hMD-PCs) remains to be studied. OBJECTIVE: To identify the biological characteristics of hMD-PCs isolated from human skeletal muscle and to study their supporting effect on umbilical cord blood CD34+ cells in vitro. METHODS: (1) hMD-PCs with phenotype CD146+ CD56-CD34-CD144-CD45- were sorted from human skeletal muscle by enzymatic digestion and multiparameter fluorescence-activated cell sorting, and their biological characteristics were identified. (2) The in vitro culture system of umbilical cord blood CD34+ cells co-cultured with human CD146+ hMD-PCs (experimental group) or with human bone marrow mesenchymal stem cells (positive control group) was established. After 1, 2 and 4 weeks of co-culture, the number of cells, the colony formation ability and immunophenotype were measured and statistically analyzed. RESULTS AND CONCLUSION: (1) CD146+ hMD-PCs were sorted by multiparameter fluorescence-activated cell sorting and the purity was (91.5±1.85)% (n=5). CD146+ hMD-PCs expressed mesenchymal surface markers CD73, CD90, CD105, CD44, and did not express hematopoietic cell and endothelial cell markers CD45, CD34, and CD31. After induced culture, CD146+ hMD-PCs could differentiate into osteoblasts, chondrogenesis, adipocytes and myoblasts. (2) There were no significant differences in the cell number, colony f ormation ability or immunophenotype (CD45+, CD34+ CD33-, CD14+, CD10+/CD19+) between experimental and positive control groups (P > 0.05, n=6). The number of cells in the blank control group without feeder was significantly decreased at 1 week of culture, and there was almost no cell survival at 2 weeks of culture. (3) In summary, CD146+ hMD-PCs, like human bone marrow mesenchymal stem cells, have hematopoietic support capacity in vitro.

Objective To explore the effects of application of standard evaluation process of spinal cord motor function in patients with thoracic or lumbar diseases. Methods Selected 60 patients with thoracic and lumbar disease treated in the orthopedic ward of Henan Provincial People's Hospital from April 2016 to June 2016 as the experimental group. We retrospectively analyzed 60 cases of patients with thoracic or lumbar diseases treated with routine nursing evaluation process admitted between January to March 2016. We compared before and after the standardization evaluation process of spinal cord motor function, the theory and operation achievements of nurses, satisfaction of doctors with nurse specialist ability, mean hospitalization days and average cost of two groups. Results The development and implementation of the standardized evaluation process of spinal motor neurotically function, after the training, the theoretical assessment score of the nurse was (94.70±1.18) points, and the operation assessment score was (93.50±2.34) points; the average length of stay was (6.10±1.98) days. The average cost of hospitalization was (29 088±341) yuan; the overall satisfaction of doctors to nurses increased to 14/15; compared with 42.30±12.95, 46.80±15.31, 7.80±2.37, 37 566±592 of the control group, the difference was statistically significant (t=4.76-8.31, P=0.00). Conclusion Application of the standard evaluation process for Spinal cord motor function in patients with thoracic or lumbar diseases can standardize nurses' working procedure, making nursing work more comprehensive, timely and professional, and can better guide clinical practice.

Objective Analysis of community work personnel's general practitioner engaged in service intention and its influencing factors. Methods Between December 2016 and May 2017, using multi-stage cluster random sampling in the Urumqi area,across 7 community health service centers(CHSC) out of 59 in a county jurisdiction,we randomly selected 1-2 community health service centers in each area county.Wethen randomly selected 8 CHSC staff as the research participants and chose a total of 324 community work personnel, 66 male and 258 female, with an average age of (34.7 ± 10.4) years to complete a questionnaire survey.The general practitioner engaged with theservice staff will use chi-square test analysis and logistic regression analysis on the influencing factors. Results Of 324 medical workers in community health service centers, including 250 of Han ethnic group and 74 minority ethnic group workers, 97.6% workers of Han ethnic group and 95.9% of minority ethnic group had signing service awareness; 92.4% of Han workers would sign system services,and 95.9% of the minority ethnic group staff were willing to sign system services. Single factor analysis found that the staff were familiar with the signing system service, attended the health management training in general medicine,had teacher-training background,had teaching experience,wondered whether to have interns,wondered whether it can save manpower,wondered whether workload could be reduced, wondered whether it can improve compliance, and considered doctor-patient relationship. These nine parameters represented service contracts with the GPS system and showed statistically significant differences (χ2=6.433, 12.913, 5.984, 6.448, 14.593, 20.675, 17.031, 84.829, 97.943, respectively;P< 0.05). In the comparison of Han ethnic group and minority workers' signing intention,the nine indicators showed no significant differences(P>0.05).Conclusion Urumqi Han ethnic group and minority community workers' a wareness of signing service, willingness to sign system services, strengthening community staff of general medicine,and training for health management knowledge and skills are advantageous to the community engaged in service.

Aim To investigate the antitumor and antiangiogenic effects of combined low-dose cyclophosphamide(CTX)and recombined VEGF protein vaccine.Methods In this experiment,H22 hepatocellular carcinoma model was established in BALB/c mice.Mice were randomly divided into four groups: control group,CTX group(CTX),VEGF protein vaccine group(V2)and CTX plus V2 group(CTX+V2).The anti-tumor efficacy and antiangiogenic effect were investigated using a subcutaneous tumor model and an intradermal tumor model.Western blot and ELISAwere further adopted to detect the specific anti-VEGF antibody.Results CTX+V2 group displayed a lower tumor volume and tumor weight than either the single therapy group in the subcutaneous tumor model(P<005 vs V2,P<001 vs CTX).Meanwhile,CTX+V2 was more effective for antagonizing tumor-associated angiogenesis compared with either the single therapy(P<005 vs V2,P<001 vs CTX).After CTX+V2 immunization,high titer of anti-VEGF antibody was detected by ELISA and verified by Western blot.Conclusion The therapy of CTX combined with V2 has significant synergistic effect against H22 hepatocellular carcinoma.
