Objective: To investigate the distribution characteristics of CD36 antigen in healthy individuals in Xinjiang, China and analyze the molecular mechanisms underlying CD36 deficiency. Methods: Flow cytometry was used to assess CD36 antigen expression on platelets from 881 healthy individuals who underwent physical examinations between June and August 2023. Differences in CD36 antigen distribution among ethnic groups were compared, and genotyping and third-generation sequencing were conducted on samples with CD36 deficiency. Results: Among the 881 samples, 4 cases (0.5%) of CD36 type Ⅱ deficiency were identified. The deficiency frequency was 0.7% (3/430) in Han individuals and 0.3% (1/363) in Uygur individuals, with no statistically significant difference between the two groups (P>0.05). No mutations were detected in the coding regions of the deficient samples. Two samples exhibited a (TG)11 in intron 3. Among the 12 linked mutation sites, g. 55589 G>A was mutated to g. 55589G Del, while g. 55593 A del did not occur; however, g. 55591A>T was observed nearby. Additionally, 52742insGAAAA was present in 100% of the (TG)11 haplotypes, potentially representing a novel linked mutation. Conclusion: This study indicates that the positive frequency of CD36 antigen in Xinjiang is relatively high, suggesting a low risk of alloimmune diseases in clinical practice. The (TG)11 in intron 3 is not universally present in all CD36 type Ⅱ deficiency cases, and the number of linked mutation sites extends beyond the previously reported 12.

In this paper， by referring to ancient and modern literature， the textual research of Kochiae Fructus has been conducted to clarify the name， origin， distribution of production areas， quality specification， taste and efficacy， harvesting time， processing and compatibility taboo， so as to provide reference and basis for the development and utilization of related famous classical formulas. According to the investigation， it can be seen that Difuzi was first published in Sheng Nong's Herbal Classic， and has been used as the official name throughout history. It is also known by other names such as Dimai， Dikui， and Luozhou. The mainstream source of Difuzi in materia medica throughout history is the dried ripe fruit of Kochia scoparia， which is consistent throughout history. In the Han dynasty， it was recorded that Kochiae Fructus was produced in Jingzhou（Hubei province）， while modern literature records its distribution throughout the country， so it does not have obvious geoherbalism. The harvesting period of Kochiae Fructus is mostly in the late autumn， and the quality is best when it is full， gray green in color， and no impurities. There are two processing methods for its origin：from the Southern and Northern dynasties to the Ming dynasty， it was dried in the shade， and after the founding of the People's Republic of China， it was dried in the sun. There are few records about the processing of Kochiae Fructus， and its clinical application is mostly based on raw products as medicine. The seedlings are harvested in February of the lunar calendar， and the leaves are taken in April and May， processing in the place of origin is shade drying， the processing methods include burning ash and frying frost， pounding juice and wine soaking. For internal use， it is mostly decocted or mashed， while for external use， it is mostly washed with decoction or taken in a soup bath. Throughout history， it has been recorded that Kochiae Fructus is bitter and cold， and is mainly used for treating bladder fever. After the founding of the People's Republic of China， most of the literature classified it as damp-clearing medicine. Since the 1985 edition of Chinese Pharmacopoeia， it has been recorded that Kochiae Fructus has a pungent and bitter taste， and a cold nature. Returning to the kidney and bladder meridians with functions of clearing heat and dampness， dispelling wind and relieving itching. The clinical contraindications are mainly prohibited for those with deficiency and no dampness and heat. Throughout history， it has been recorded that the taste of the seedlings and leaves is bitter and cold for treatment of dysentery. Since modern times， it has been used to regulate the liver， spleen and large intestine meridians， with functions such as clearing heat and detoxifying， and diuresis. Based on the textual research， it is recommended to use the dried ripe fruit of K. scoparia when developing the famous classical formulas containing Kochiae Fructus， and processing shall be carried out according to the original processing requirements. If the original formula does not specify the processing requirements， the raw products is taken into medicine.

Objective: To investigate the distribution characteristics of Kidd blood group antigens, phenotypes and genotypes in Xinjiang and their influence on the risk of coronary heart disease. Methods: Samples from 7 981 patients treated at People's Hospital of Xinjiang Uygur Autonomous Region from August 1, 2023 to May 31, 2024 were collected for Jk(a-b-) phenotype screening via urea hemolysis test, followed by the third-generation sequencing (TGS). Kidd blood group Jk and Jk antigens in 1 081 patients with coronary heart disease and 1 021 healthy people were detected, and their phenotype frequency distribution was analyzed and corresponding gene frequencies were calculated. Correlation analysis and logistic regression were used to evaluate the influence of Kidd blood group antigen expression on coronary heart disease risk. Results: Two Jk(a-b-) phenotype samples were detected, both resulting from novel gene mutation combinations. Comparative analysis of two groups revealed a higher proportion of the Jk(a-b+) phenotype in the case group (22.5%, 243/1 081) than in the control group (18.5%, 189/1 021). Moreover, Kidd blood group phenotype distribution varied significantly across all ethnic groups in the case group (P<0.05). In the control group, the Hui ethnic group exhibited the highest JK JK genotype frequency 64.15% (34/53). In the case group, the highest JK allele frequency was observed in Mongol ethnic group 56.31% (125/222), and the lowest in Han patients 45.71% (341/746). The expression of Jk antigen was negatively correlated with coronary heart disease (P<0.05). Conclusion: The distribution of Kidd blood group system varied across ethnic groups in Xinjiang. The expression of Jk antigen may have protective effect on coronary heart disease, which provides a basis for future clinical blood transfusion treatment and the mechanism study of the correlation between Kidd blood group and coronary heart disease.

In this paper， by referring to ancient and modern literature， the textual research of Cnidii Fructus has been conducted to clarify the name， origin， distribution of production areas， quality specification， nature and flavour， efficacy， harvesting and processing， compatibility taboo and others， so as to provide reference and basis for the development and utilization of the relevant famous classical formulas. After textual research， it can be verified that Cnidii Fructus was first published in Sheng Nong's Herbal Classic， the materia medica of all dynasties was named Shechuangzi， and there are also aliases such as Shesu， Shemi， and Qiangmi. The main source for generations was the dried ripe fruit of Cnidium monnieri， and ancient and modern consistent. From the Eastern Han dynasty to Tang dynasty， the origin of Cnidii Fructus was Zibo， Shandong province. During the Five dynasties， it expanded to Yangzhou in Jiangsu province and Xiangyang in Hubei province， the Song dynasty added Shangqiu in Henan province， and it was considered that Yangzhou， Xiangyang and Shangqiu were its genuine producing areas. It was more widely distributed in Ming and Qing dynasties. After the founding of the People's Republic of China， the origin is clearly distributed throughout the country. For its quality evaluation， generally full grain， gray yellow color， strong aroma is the best. The harvesting period in the past dynasties was mostly the fifth lunar month， and the fruit was collected to remove impurities and dry. The mainstream processing in producing area of the past dynasties was net selection of raw products， mixing and steaming with the juice of Rehmanniae Radix and stir-frying were the mainstream processing methods in the past， there were also stir-frying with honey， stir-frying with salt and rice wine， immersing and steaming with rice wine and other methods. In recent times， it has been used in raw products as medicine. Sheng Nong's Herbal Classic recorded Cnidii Fructus was bitter， Supplementary Records of Famous Physicians recorded its acrid for the first time. It was recorded in the Ming dynasty that its nature was warm， acted on the kidney meridian， and had small toxicity. After the founding of the People's Republic of China， most of the literature classified it as a medicine to attack poison， kill insects and relieve itching with the functions of dispelling pathogenic wind and removing dampness， destroying parasites and elieving itching， warming kidney and activating Yang. Clinical contraindications are mainly contraindicated for people with damp-heat from the lower-jiao or kidney heat. Based on the textual research， it is suggested that when developing the famous classical formulas containing Cnidii Fructus， the source shall be the dried ripe fruit of C. monnieri， and then it shall be processed according to the original formulas. If there is no requirement for processing in the formulas， the raw products can be taken into medicine.

Objective To explore the value of oral contrast-enhanced ultrasonography (OCEUS) combined with contrast-enhanced CT in predicting preoperative T staging in patients with gastric cancer. Methods A retrospective analysis was conducted on 80 patients with gastric cancer confirmed via endoscopic biopsy or postoperative pathology at the First People’s Hospital of Jining from January 2021 to November 2024. The cohort included 56 males and 24 females, aged 38-79 years, with a median age of 55.9 years. All patients underwent both OCEUS and contrast-enhanced CT within one week prior to surgery. T staging of gastric cancer was determined using OCEUS, contrast-enhanced CT, or their combination. The results were compared with pathological T staging, and statistical differences in accuracy were analyzed. Results Pathological T staging identified T1 in 9 cases, T2 in 16 cases, T3 in 42 cases, and T4 in 13 cases. OCEUS indicated T1 in 6 cases, T2 in 14 cases, T3 in 50 cases, and T4 in 10 cases, with an accuracy rate of 80.0%. Contrast-enhanced CT indicated T1 in 4 cases, T2 in 12 cases, T3 in 52 cases, and T4 in 12 cases, with an accuracy rate of 75.0%. The combination of OCEUS and contrast-enhanced CT indicated T1 in 6 cases, T2 in 15 cases, T3 in 47 cases, and T4 in 12 cases, with an accuracy rate of 87.5%. The combined approach demonstrated significantly higher accuracy in preoperative T staging compared to either method alone (P < 0.05). Conclusion The combination of OCEUS and contrast-enhanced CT improves the accuracy of preoperative T staging in gastric cancer patients, providing valuable support for their diagnosis and treatment.

ObjectiveTo investigate the recurrence of ischemic stroke (IS) and to analyze the association between four indices of total cholesterol (TC), low-density lipoprotein cholesterol (LDL-C), high-density lipoprotein cholesterol (HDL-C), and triglycerides (TG) and the risk of IS recurrence by analyzing the follow-up data related to IS in the community-based natural population of Songjiang District, Shanghai, so as to provide a scientific basis for improving the prognosis of stroke patients in the community and controlling IS recurrence. MethodsA prospective follow-up study was conducted among the IS patients in the community-based cohort population, collecting data about patient’s age, gender, disease history, biochemical indicators, and etc. Cox regression model and restricted cubic spline model were used to analyze the relationship between different levels of plasma lipids and the recurrence of IS in these patients. ResultsA total of 1 368 patients with IS were included. The total follow-up duration was 7 171.46 person-years, with a median follow-up time of 6.24 years. There were 420 cases of IS recurrence, resulting in a cumulative recurrence rate of 30.70%. The results of multivariate Cox regression analysis showed that the recurrence risk of IS was reduced when the baseline TC and LDL-C levels of IS patients were in the ranges of 4.65‒5.67 mmol·L^-1 and 2.52‒3.46 mmol·L^-1, respectively. The results of restricted cubic spline analysis showed a U-shaped relationship between baseline TC and LDL-C levels and the recurrence risk in IS patients. ConclusionThe cumulative recurrence rate of patients with IS in the community of Songjiang District in Shanghai is high, and the levels of TC and LDL-C at baseline survey are correlated with the recurrence of IS in these patients. It is suggested to pay more attention to the levels of LDL-C and TC in patients with IS, so as to improve the prognosis.

Objective:To investigate the efficacy and safety of Ropivacaine combined with Lidocaine for incision infiltration anesthesia in lumbar fusion surgery.Methods:The case data of 154 patients with lumbar degenerative diseases who underwent lumbar fusion surgery at the Department of Orthopedics, Beijing Friendship Hospital, Capital Medical University from March 2021 to September 2023 were retrospectively analyzed, and the patients were divided into the experimental group ( n=72) and the control group ( n=82) according to whether or not they underwent Ropivacaine combined with Lidocaine incisional infiltration anesthesia. The experimental group was anesthetized with Ropivacaine combined with Lidocaine incisional infiltration anesthesia, and the control group was not anesthetized with incisional infiltration. The static and dynamic pain visual analog score (VAS) at six postoperative time points (2, 4, 6, 12, 24, 48 h after surgery), the application of postoperative analgesic medications, and related complications were compared between the two groups. The measurement data of normal distribution were expressed as mean±standard deviation( ± s), and t-test was used for comparison between groups, the measurement data of non-normal distribution were expressed as median (interquartile distance) [ M( Q1, Q3)], and non-parametric test was used for comparison between groups; the count data were expressed as the number of cases and percentage, and the Chi-square test was used for comparison between groups. Results:All patients underwent successful surgery, and the static [(4.40±1.67), (3.86±1.22), (3.58±1.15), (3.43±1.11) points] and dynamic [(4.56±1.69), (4.03±1.21), (3.79±1.16), (3.65±1.13) points] VAS scores of the patients in the experimental group were lower than those in the control group [static: (5.38±1.73), (5.06±1.58), (4.68±1.37), (3.82±1.22) points; dynamic: (5.55±1.62), (5.29±1.50), (4.89±1.41), (4.12±1.29) points] at 2, 4, 6, 12 h after surgery, and the differences were statistically significant ( P<0.05); at 24, 48 h after surgery, there was no significant difference in the static and dynamic VAS scores between the two groups ( P>0.05). The dosage of oral Tramadol [100(0, 100) mg] and subcutaneous injection of Morphine [0(0, 0) mg] in the experimental group at 48 h after surgery were significantly lower than those in the control group [100(100, 100), 0(0, 10) mg], and the differences were statistically significant ( P<0.05). There was no significant difference in the incidence of postoperative incision complications and cerebrospinal fluid leakage between the two groups ( P>0.05). Conclusion:Ropivacaine combined with Lidocaine for incision infiltration anesthesia in lumbar fusion surgery can effectively relieve early pain in the surgical area, reduce the use of postoperative analgesic medications, and will not increase related complications.

Aim To explore the effect and mechanism of the artesunate(ART)on hepatocellular carcinoma(HCC).Methods The cell lines MHCC-97H and HCC-LM3 were used to be detected.MTT and clone formation were used to determine the cell proliferation;Wound healing was used to detect the cell migration;Transwell was used to test the cell invasion.Flow-cy-tometry was used to detect cell apoptosis and cell cy-cle.RNA-seq and qRT-PCR was used to detect the genes expression.Results The proliferation,migra-tion and invasion of treated cells were obviously inhibi-ted(P＜0.01).Moreover,the apoptosis rate in-creased significantly,so did the proportion of G2/M cells.Transcriptomic analysis identified GADD45A as a potential target of ART through RNA-sequencing da-ta,and suggested that ART might induce apoptosis and cell cycle arrest through regulating the expression of GADD45A.In addition,the results of mechanism studies and signaling analysis suggested that GADD45A had interaction with its upstream gene NACC1(nucle-us accumbens associated 1).Moreover,after ART treatment,the expressions of GADD45A and NACC1 were changed significantly.Conclusion ART may be a potential drug to resist HCC by affecting the expres-sion of GADD45A and its upstream gene NACC1,which provides a new drug,a new direction and a new method for the clinical treatment of HCC.
