Objective To explore the polymorphism and distribution of apolipoprotein E(ApoE)gene in patients with hyperlipidemia.Methods A total of 370 hyperlipidemia patients diagnosed at Hangzhou Ninth People's Hospital from October 2023 to June 2024 were selected.Gene polymorphism was detected in the blood samples of the patients using fluorescence polymerase chain reaction,and the distribution of gene polymorphism among different genders and age groups within this population was compared.Results ①The polymorphism distribution of the two genetic loci(ApoE 388T＞C and ApoE 526C＞T)in the studied sample population conforms to Hardy-Weinberg equilibrium,indicating that it is representative of the population;②Among the 370 patients,the distribution of the ApoE gene was as follows:E3/E3(66.49％),E3/E4(20.27％),E2/E3(8.65％),E2/E4(1.89％),E2/E2(1.35％),and E4/E4(1.35％).The proportion of the patient population carrying the E4 allele was about 1.88 times higher than that of those carrying the E2 allele;③The distribution differences of ApoE gene polymorphism were not related to the patients'gender and age(P＞0.05).Conclusion The distribution of ApoE gene polymorphism among hyperlipidemia patients at a hospital in Hangzhou is uneven and is not related to gender or age groups.Therefore,it is recommended to prioritize the detection of ApoE gene in patients before using statin medications to assess treatment effectiveness.

Objective:To explore the relationship between serum anti-Müllerian hormone (AMH) level and related clinical factors in healthy females, and establish and validate equation of correlation between age and serum AMH level for healthy females.Methods:From March 2015 to December 2016, a total of 602 females who measured serum AMH level in Department of Nuclear Medicine, the Second Affiliated Hospital of Soochow University were retrospectively enrolled. All cases had relatively complete clinical data, and were divided into healthy group (484 cases, 20-52 years) and case group (118 cases, 20-42 years; patients with menstrual disorders). Relationships between serum AMH level and estradiol (E2), tesosterone (T), follicle stimulating hormone (FSH), luetinizing hormone (LH), body mass index (BMI) of healthy group were analyzed by Spearman rank correlation. Kruskal-Wallis rank sum test was used to analyze the relationship between history of gestation and serum AMH level. Serum AMH level of health group was processed to establish predictive equation for serum AMH level. Internal ( n=27) and external ( n=37) validation group were chosen from healthy females with serum AMH level measured to validate the equation, and signed rank test was used to analyze the data. Difference between serum AMH level in case group and healthy group with corresponding age was explored by independent-sample t test. Results:Serum AMH levels were positively correlated with E2 and T ( rs values: 0.263, 0.334, both P<0.001), and negatively correlated with FSH, LH, BMI ( rs values: from -0.515 to -0.110, all P<0.005). Predictive equation was established as LogAMH=-1.208+ 0.1×age-0.000 042×age 3 ( R2=0.735, P<0.001). No statistically significant difference was found between real serum AMH levels and calculated serum AMH levels in the internal and external validation groups ( z values: -1.62 and -1.52, both P>0.05). Females in case group ( n=118) and control group ( n=446) were divided into two sub-groups respectively (<35 years and ≥35 years), and serum AMH levels of case group were lower than those of control group with corresponding age ( t values: 18.64, 11.70, both P<0.001). Conclusions:In healthy females, serum AMH level is related to some clinical data. The equation between serum AMH level and age established in the study may provide reference for clinical diagnosis and treatment.

ObjectiveTo investigate the effect of Shengjiang Tonglong prescription hollow suppository on rats with prostate hyperplasia， and the effect of the proteins related to phosphoinositide 3-kinase/protein kinase B （PI3K/Akt） signaling pathway in the prostate， thus exploring the mechanism of Shengjiang Tonglong prescription hollow suppository in the treatment of rats with prostate hyperplasia. MethodTen SD male rats were randomly selected from 60 SD male rats to form a sham operation control group， and the rest rats were subcutaneously injected with testosterone propionate for 4 consecutive weeks after castration to induce the rat model of prostatic hyperplasia. According to the random number table method， the 50 rats were randomly divided into a model group， a finasteride group （0.45 mg·kg^-1）， and three high， middle， and low-dose Shengjiang Tonglong prescription hollow suppository groups （3.98， 1.99， 0.99 g·kg^-1）， with ten rats in each group. After castration for 7 d， the sham operation control group and the model group used the blank hollow suppositories， and the finasteride group and the Shengjiang Tonglong prescription hollow suppository groups used the corresponding hollow suppositories. The drugs were given to the rats by anal plugs continuously for 28 d. The rats were then killed， and the prostate tissues were separated and weighed to observe the effects of drugs on the prostate index of rats in each group. The hematoxylin-eosin （HE） staining was used for the pathological observation of the prostate tissues. The level of dihydrotestosterone （DHT） was detected by enzyme-linked immunosorbent assay （ELISA）. Western blot was used to detect the expression levels of PI3K/Akt signaling pathway protein， B-cell lymphoma-2 （Bcl-2）， cysteine aspartate-specific protease-3 （Caspase-3）， Bcl-2-associated X protein （Bax）， and αB-crystallin （CRYAB） protein in the prostate tissues. ResultAs compared with the sham operation control group， the protein expression levels of prostate index， DHT level， CRYAB， Bcl-2， PI3K， and Akt in the model group were increased， and the protein expression levels of Caspase-3 and Bax were decreased （P<0.05， P<0.01）. As compared with the model group， the prostate index in the high-dose Shengjiang Tonglong prescription hollow suppository group was decreased （P<0.05）， and the level of DHT and the protein expression levels of CRYAB， Bcl-2， PI3K， and Akt in the prostate of the Shengjiang Tonglong prescription hollow suppository groups were decreased， and the protein expression levels of Caspase-3 and Bax were increased （P<0.05， P<0.01）. ConclusionShengjiang Tonglong prescription hollow suppository decreases the expression of CRYAB protein， negatively regulates the PI3K/Akt signaling pathway， down-regulates the level of DHT and the protein expression levels of Bcl-2， PI3K， and Akt， and up-regulates the protein expression levels of Caspase-3 and Bax， thereby inhibiting cell proliferation and promoting cell apoptosis， which plays a therapeutic role in the benign prostate hyperplasia （BPH）. The high-dose Shengjiang Tonglong prescription hollow suppository significantly improves prostatic hyperplasia in rats.

The integrity of the blood-brain barrier (BBB) is important for maintaining the function of the central nervous system. Its leakage can occur prior to structural changes. At present, the role of BBB leakage abnormalities in the occurrence and development of cognitive impairment has attracted attention, and it has been found that Alzheimer's disease and vascular cognitive impairment are related to BBB leakage abnormalities. This article reviews the pathophysiology of BBB leakage in Alzheimer's disease and vascular cognitive impairment.

Purpose: Cervical cancer is one of the most fatal diseases among women in under-developed countries. To improve cervical cancertreatment, discovery of new targets is needed. In this study, we investigated the expression of NUP210, miR-22, and Fas in cervicalcancer tissues and their functions in cell cycle regulation. Materials and Methods: We detected and compared the expression levels of NUP210, miR-22, and Fas in cervical cancer tissueswith paired normal tissues using immunohistochemistry, Western blot, and real-time quantitative polymerase chain reaction.NUP210 was knocked down in HeLa cells via lentivirus, followed by cell cycle and proliferation analysis. Using a luciferase reporterassay, we explored the link between miR-22 and NUP210. We overexpressed miR-22 in HeLa cells and analyzed cell cycle and proliferationfunction. We then overexpressed miR-22 in NUP210 knockdown cells to explore the connection between Fas and miR-22-NUP210 signaling. Results: We found that NUP210 was overexpressed in cervical cancer patients. Knocking down NUP210 restored cell apoptosisand proliferation. We confirmed miR-22 as a regulator of NUP210 and verified that miR-22 was inhibited in cervical cancer development.We also found that restoring miR-22 expression could induce cell apoptosis. Finally, we found that miR-22-regulated expressionof NUP210 could alter Fas expression and, in turn, elicit cell cycle arrest and proliferation. Conclusion miR-22 in cervical cancer is downregulated, resulting in NUP210 overexpression and inhibition of Fas-induced cellapoptosis.

Objective To assess the efficacy and safety of berberine, amoxicillin, lansoprazole, bismuth quadruple therapy for Helicobacter pylori (H.pylori)eradication.Methods From December 2015 to April 2016,566 patients with initial treatment of H.pylori infection were prospectively enrolled.Patients were divided into observation group (berberine, amoxicillin, lansoprazole, bismuth) and control group (clarithromycin, amoxicillin, lansoprazole, bismuth), 283 cases in each group, and the treatment courses in two groups were both 14 days.Four weeks after completion of the treatment, the eradication rate of H.pylori and adverse effect rate of the two groups were compared.Student t test and Chi square test were performed for comparison between the two groups.Results There was no statistically significant difference in the baseline demographic data including gender,age, body mass index (BMI), symptom score between patients of the two groups (all P>0.05).Four weeks after completion of the treatment, the eradication rates of observation group and control group were 87.5%(244/279) and 87.1%(242/278) according to per-protocol analysis, and which were 86.2%(244/283) and 85.5 %(242/283) according to intention-to-treat analysis.There was no statistically significant difference between the two groups (x2=0.021,0.058;both P>0.05).The adverse effect rates of the two groups were 12.5%(35/279) and 16.5%(46/278), and there was no statistically significant difference (x2=1.795,P=0.180).Conclusions Both the new quadruple regimen containing berberine, amoxicillin and bismuth, and the standard quadruple regimen containing clarithromycin, amoxicillin and bismuth both can effectively eradicate H.pylori infection.The new regimen might be recommended as first-line eradication regimen in Xi′an district or area with high clarithromycin resistance.

Objective To evaluate the clinical application of TCM nursing therapies and identify the problems during the therapy implementation, in order to explore the countermeasures to promote its clinical improvement. Methods A descriptive cross-sectional study was conducted,and a self-designed questionnaire was employed to investigate 218 nurses from 148 grade A class three TCM hospitals in China. Results 25 TCM nursing therapies were implemented in these hospitals. Ear acupressure therapy was the most frequently implemented,accounting for 83.5%(182/218);while wax therapy was the least implemented, accounting for 7.8%(17/218). The implementation frequency of these technologies varied significantly, 0~860 times a week. The top three of them were acupoint application therapy, hot compression of Chinese medicine and ear acupoints therapy.TCM nursing therapies were considered to be the most frequently used in insomnia, headache, edema, arthralgia, cold, epigastric pain, hypochondriac pain and fever.Storage of TCM nurses,lacking of TCM knowledge and inapposite therapy implementation were the main problems in the application. Conclusions Scientific and rational allocation of human resources, cultivation of the TCM-specific nursing professional, enhancement of nurses'awareness of Chinese medicine, establishment of a reasonable charging standard, and strengthening the risk management in implementation will promote its clinical development.

Objectives To investigate the diagnostic performance of the combination of ultrasound elastography and automated breast volume scanner (ABVS) in differentiation of benign and malignant breast imaging reporting and data system (BI-RADS) 4 breast lesions. Methods Data from 137 breast cancer patients (147 tumors) confirmed pathologically were analyzed. Each tumor was examined by ABVS and ultrasound elastography. All tumors were diagnosed as BI-RADS 4 by ABVS. With final pathology results as the gold standard, the predictive value in differentiating BI-RADS 4 breast lesions between ultrasound elastography and the combination of ultrasound elastography and ABVS were compared. Results There were 54 benign nodules and 93 malignant nodules in this study. The diagnostic sensitivity of ultrasound elastography and the combination of ultrasound elastography and ABVS were 94.6% and 98.9%,the specificity were 57.4% and 57.4%, the accuracy were 81.0% and 83.7%, the area under the curve were 0.858 and 0.965, respectively. The diagnostic performance of ultrasound elastography combined with ABVS was better than that of ultrasound elastography. Conclusions Ultrasound elastography have certain value in differential diagnosis of BI-RADS 4 breast lesions, especially when combining with ABVS, which will improve its diagnostic accuracy. Ultrasound elastography combined with ABVS can improve the detection rate of malignant lesions in BI-RADS 4 breast lesions and reduce the rate of preoperative biopsy, and it has a good application prospect.

Objective: To investigate the effect of interleukin-22 (IL-22) on the activation and proliferation of hepatic stellate cells (HSCs) induced by acetaldehyde, as well as the role of the antioxidant axis Nrf2-keap1-ARE. Methods: Hepatic stellate cell-T6 (HSC-T6) cells were cultured in vitro, and after 24 and 48 hours of acetaldehyde stimulation at various concentrations (25, 50, 100, 200, and 400 μmol/L), MTT assay was used to measure cell proliferation rate to screen out the optimal conditions for model establishment. HSC-T6 cells were treated first with the optimal concentration of acetaldehyde (200 μmol/L) for 24 hours and then with different concentrations of IL-22 (10, 20, and 50 ng/ml) for 24 hours. MTT assay was used to measure cell proliferation, Western blot and cell immunohistochemistry were used to measure the expression of nuclear factor erythroid 2-related factor 2 (Nrf2) and α-smooth muscle actin (α-SMA), and spectrophotometry was used to measure the changes in the content of malondialdehyde (MDA) and reduced glutathione (GSH) in culture supernatant. SPSS 17.0 was used for statistical analysis and data were expressed as mean±SD. P < 0.05 was considered statistically significant. A one-way analysis of variance was used for comparison of means between any two groups. Results: HSCs had significantly enhanced proliferation and activation after being treated with acetaldehyde, especially at 200 μmol/L for 48 hours. After the intervention with gradient concentrations of IL-22, the proliferation and activation of HSCs were inhibited in a dose-dependent manner, and the proliferation and migration rates in the 10, 20, and 50 ng/ml IL-22 groups were 14%, 25%, and 35%, respectively (all P < 0.05). The results of Western blot and immunohistochemistry showed that there was no significant difference in the expression of Nrf2 total protein in HSCs between groups, while there was extremely low expression of Nrf2 nucleoprotein in the blank control group. There was increased expression of Nrf2 nucleoprotein after acetaldehyde stimulation (compared with the blank control group, P < 0.05), and after the intervention with gradient concentrations of IL-22, the expression of Nrf2 nucleoprotein was further increased (all P < 0.05). The results of spectrophotometry showed that compared with the blank control group, the model group had increased levels of MDA and GSH in culture supernatant after acetaldehyde stimulation; after the intervention with gradient concentrations of IL-22, there was a significant reduction in the MDA level and a significant increase in the GSH level in a dose-dependent manner (all P < 0.05). Conclusion The activation and proliferation of HSCs induced by acetaldehyde helps with the successful establishment of an in vitro model of alcoholic liver fibrosis. IL-22 effectively inhibits the activation and proliferation of HSCs induced by acetaldehyde, and its mechanism may be related to promoting Nrf2 nuclear translocation in HSCs and expression of the downstream target gene GSH and increasing the activity of the antioxidant axis Nrf2-keap1-ARE.
