ObjectiveTo investigate the effects of Ningxin Shugan decoction combined with an antagonist fixation regimen on in vitro fertilization and embryo transfer （IVF-ET） outcomes and serum kisspeptin expression in infertility patients with polycystic ovary syndrome. MethodsA total of 96 infertile patients with polycystic ovary syndrome treated in Yancheng No.1 People's Hospital and Yancheng Affiliated Hospital of Nanjing University of Chinese Medicine were enrolled in this study and randomized into control and observation groups （n=48）. The control group was treated with an antagonist fixation regimen， and the observation group was treated with Ningxin Shugan decoction on the basis of the treatment in the control group. The clinical efficacy was compared between the two groups. The total score and single scores of TCM symptoms， ovulation promotion status， and serum levels of reproductive hormones， miR-335-5p， miR-141-3p， and kisspeptin were determined before and after treatment. The IVF-ET outcome indicators and treatment safety were evaluated. Pearson test was conducted to analyze the correlations of serum levels of follicle-stimulating hormone （FSH）， kisspeptin， miR-335-5p， and miR-141-3p with IVF-ET outcomes. ResultsThe total response rate in the observation group was 90.91%， which was higher than that （70.45%） in the control group （P<0.05）. The total score and single scores of TCM symptoms and the testosterone， luteinizing hormone （LH）， and LH/FSH levels declined after treatment （P<0.05）， and they were lower in the observation group than in the control group （P<0.05）. After treatment， the serum levels of FSH， kisspeptin， miR-335-5p， and miR-141-3p rose in both groups， being higher in the observation group than in the control group （P<0.05）. The observation group showed higher ovulation number， number of MⅡ oocytes， embryo implantation rate， clinical pregnancy rate， and live birth rate than the control group （P<0.05， P<0.01）. Serum levels of FSH， kisspeptin， miR-335-5p， and miR-141-3p were positively correlated with embryo implantation rate， clinical pregnancy rate， and live birth rate （P<0.01）. ConclusionNingxin Shugan decoction combined with the antagonist fixation regimen can improve the IVF-ET outcome， promote the serum kisspeptin expression， and increase the ovulation rate and pregnancy rate in infertility patients with polycystic ovary syndrome.

Objective To investigate the safety, efficacy, and clinical value of a fracture reduction and fixation system. Methods The design and application of components [Kirschner wire (K-wire) limiter and K-wire guiding locking device] of the fracture reduction and fixation system were described. Six surgeons implanted K-wires into synthetic bones using the K-wire limiter or by perception respectively, and the length of K-wire protrusion was assessed. K-wire guiding locking device combined with locking plates and two 1.5 mm K-wires, two 1.5 mm K-wires, as well as two 2.0 mm K-wires were used to fix a fracture model constructed by synthetic bones, and the torque at failure was measured. Results The K-wire limiter reduced the length of K-wire protrusion(P < 0.001). The failure torque of fractures fixed by K-wire guiding locking device with locking plates and two 1.5 mm K-wires was larger than those fixed with two 1.5 mm K-wires and two 2.0 mm K-wires(P < 0.05). Conclusion The fracture reduction and fixation system offers a new technique for reducing and reconstructing fractures, assessing and optimizing the position of locking plate screws, as well as protecting the blood supply of fractures.

OBJECTIVE To compare the efficacy and safety between the drug winning the bidding for centralized procurement and the original drug of ticagrelor in acute coronary syndrome （ACS） patients one year after percutaneous coronary intervention （PCI）. METHODS Overall 420 ACS patients treated with PCI in our hospital from July 2021 to June 2023 were divided into centralized procurement group （156 cases） and original drug group （264 cases） according to the different varieties of ticagrelor. All patients were given Aspirin enteric-coated tablets 100 mg regularly， once a day； on this basis， patients in the centralized procurement group were given Ticagrelor tablets winning the bidding， while patients in the original drug group were given the original drug of Ticagrelor tablets. The dosage of Ticagrelor tablets taken by both groups of patients was 90 mg， twice a day， and the course of treatment was 12 months. The blood routine indicators were compared before treatment and one week after treatment， while the incidence of net adverse clinical events （NACE）， major adverse cardiovascular and cerebrovascular events （MACCE） and bleeding events， and the survival rate without MACCE and bleeding events during a one-year follow-up after PCI were also compared between two groups. RESULTS There were no statistically significant differences in blood routine indicators before treatment and one week after treatment， as well as the incidence of NACE， MACCE and bleeding events， survival rate without MACCE and bleeding events during a one-year follow-up after PCI between the two groups （P＞0.05）. CONCLUSIONS During a one-year follow-up after PCI， the efficacy and safety of the drug winning the bidding for centralized procurement of ticagrelor are comparable to the original drug.

Cancer genomics has led to the discovery of numerous oncogenes and tumor suppressor genes that play critical roles in cancer development and progression.Oncogenes promote cell growth and proliferation,whereas tumor suppressor genes inhibit cell growth and division.The dysregulation of these genes can lead to the development of cancer.Recent studies have focused on non-coding RNAs(ncRNAs),including circular RNA(circRNA),long non-coding RNA(lncRNA),and microRNA(miRNA),as therapeutic targets for cancer.In this article,we discuss the oncogenes and tumor suppressor genes of ncRNAs associated with different types of cancer and their potential as therapeutic targets.Here,we highlight the mechanisms of action of these genes and their clinical applications in cancer treatment.Understanding the molecular mechanisms underlying cancer development and identifying specific therapeutic targets are essential steps towards the development of effective cancer treatments.

Mucinous adenocarcinoma of the renal pelvis is rare in clinical practice. This article reported a case of primary renal pelvis mucinous adenocarcinoma mixed with signet ring cell carcinoma. The patient was admitted to hospital due to right low back pain, and was diagnosed with right kidney stones accompanied by hydrops and infection, right kidney abscess, and nonfunctional right kidney after complete examination. Right renal puncture drainage was performed twice, followed by laparoscopic robot assisted right neprectomy. The postoperative pathological diagnosis was right renal pelvis primary mucinous adenocarcinoma (mixed with signet-ring cell carcinoma). Eleven months after the operation, regular "sodium folinate + oxaliplatin + 5-fluorouracil" chemotherapy was performed for 12 courses, and imaging showed no signs of recurrence or metastasis.

Objective To analyze the dynamic changes in serum adiponectin (APN) levels after acute myocardial infarction (AMI) and its relationship with heart failure (HF) and major adverse cardiovascular events (MACE). Methods A total of 124 AMI patients who underwent percutaneous coronary intervention (PCI) in our hospital from January 2021 to December 2023 were enrolled as AMI group. Additionally, 30 patients with non-AMI coronary artery disease and 30 healthy individuals were included in non-AMI coronary artery disease group and healthy group, respectively. General information such as age, gender, smoking, alcohol consumption, hypertension, diabetes, and blood lipids were recorded for all subjects. Serum APN levels were measured using the enzyme-linked immunosorbent assay (ELISA) method; plasma brain natriuretic peptide (BNP) levels were determined by immunofluorescence; and left ventricular ejection fraction (LVEF) was assessed using echocardiography. Changes in serum APN levels and its relationship with BNP, LVEF, and MACE were recorded during a one-year follow-up period. Results AMI patients had lower serum APN levels than those in the non-AMI coronary artery disease group and the healthy group, while levels of total cholesterol (TC), low-density lipoprotein cholesterol (LDL-C); Lipoprotein-associated phospholipase A2 (Lp-PLA2), and the proportions of smokers and diabetics were higher(P < 0.05). A one-year follow-up of AMI patients revealed an upward trend in serum APN and BNP levels and a downward trend in LVEF levels at one week, one month, three months, six months, and one year postoperatively (P < 0.05). APN and BNP levels peaked one month after PCI, while LVEF reached its lowest level at the same time point. However, there were no statistically significant changes in these indicators in the subsequent 11 months (P>0.05). The incidence of MACE in AMI patients at one, three, six, and twelve months postoperatively was 2.8%, 3.2%, 4.6%, and 8.8%, respectively. Both preoperative and one-month postoperative serum APN levels had high predictive value for the occurrence of HF and MACE within one year in AMI patients, and the area under the curve for predicting HF and MACE one month postoperatively was larger than that preoperatively (P < 0.05). Conclusion Serum APN levels in AMI patients show an upward trend after PCI, peaking one month postoperatively. At this time point, serum APN levels have the highest predictive value for the occurrence of HF and MACE.

The presence of replication-competent HBV DNA in the liver and/or serum of HBsAg-negative individuals is a sufficient and necessary condition for the diagnosis of occult hepatitis B virus infection (OBI). In recent years, Chinese scholars have proposed what is considered a more "rigorous" definition, i.e., on this basis, HBV window period (WP) infection is excluded, which corresponds to a serum HBV DNA level of below the lower limit of detection or a low positive value (< 200 IU/mL). As the definition of WP for HBV infection remains unclear and its duration is highly variable, "HBV DNA < 200 IU/mL" is not the only criterion in OBI patients. Therefore, it is believed that there is still a lack of sufficient basis and operability for the definition of OBI based on "the exclusion of HBV WP infection" and "HBV DNA < 200 IU/mL" as "rigorous" conditions for the diagnosis of OBI.

OBJECTIVE: To assess the value of chromosomal microarray analysis (CMA) and fluorescence in situ hybridization (FISH) for the prenatal diagnosis of chromosomal mosaicisms. METHODS: A total of 775 pregnant women who had visited the Prenatal Diagnosis Center of Yancheng Maternal and Child Health Care Hospital from January 2018 to December 2020 were selected as study subjects. Chromosome karyotyping analysis and CMA were carried out for all women, and FISH was used to validate the suspected mosaicism cases. RESULTS: Among the 775 amniotic fluid samples, karyotyping has identified 13 mosaicism cases, which yielded a detection rate of 1.55%. Respectively, there were 4, 3, 4 and 2 cases for sex chromosome number mosaicisms, abnormal sex chromosome structure mosaicisms, abnormal autosomal number mosaicisms and abnormal autosomal structure mosaicisms. CMA has only detected only 6 of the 13 cases. Among 3 cases verified by FISH, 2 cases were consistent with the karyotyping and CMA results, and clearly showed low proportion mosaicism, and 1 case was consistent with the result of karyotyping but with a normal result by CMA. Eight pregnant women had chosen to terminate the pregnancy (5 with sex chromosome mosaicisms and 3 with autosomal mosaicisms). CONCLUSION For fetuses suspected for chromosomal mosaicisms, CMA, FISH and G-banding karyotyping should be combined to determine the type and proportion of mosaicisms more precisely in order to provide more information for genetic counseling.
