This article systematically analyzed the historical evolution of the origin， scientific name， producing area， quality evaluation， harvesting and processing， and other aspects of Quisqualis Fructus by consulting the ancient materia medica， medical books， prescription books， local literature and combining with the modern literature and standards， summarized and explored the development rules of its medicinal properties and efficacy along with their underlying causes， in order to provide support for the development and utilization of famous classical formulas containing this herb. According to the textual research， Shijunzi was first recorded as Liuqiuzi in Nanfang Caomuzhuang of the Jin dynasty， and the name of Shijunzi was first used in Kaibao Bencao of the Song dynasty， which has been consistently used throughout subsequent dynasties， and there were also aliases such as Junziren， Sijunzi， and Dujilizi. The mainstream source of Quisqualis Fructus used in the past dynasties has been the dried mature fruits of Quisqualis indica， a plant belonging to the family Combretaceae. In modern times， its variety Q. indica var. villosa has also been recorded as the medicinal material of Quisqualis Fructus. In 2007， the Flora of China（English edition） designated Q. indica var. villosa as a synonym of Q. indica. Today， the accepted name of Shijunzi is updated to Combretum indicum. According to ancient herbal records， the producing areas of Quisqualis Fructus were Guangdong， Hong Kong， Macao， Guangxi， Hainan， Sichuan and Fujian， and then gradually expanded to Yunnan， Taiwan， Jiangxi and Guizhou. Since the Song dynasty， two major production regions have gradually emerged in Sichuan， Chongqing and Fujian. Currently， it is primarily cultivated in Chongqing， Guangxi and other areas， with Chongqing yielding the highest output. Since modern times， superior quality has been defined by large size， a purple-black surface， plump grains， and a yellowish-white kernel. According to ancient herbal records， the harvesting period of Quisqualis Fructus was the July and August of the lunar calendar， mostly used raw after shelling or with the shell intact， it underwent processing methods such as cleaning， slicing， mixing， steaming， roasting， stewing， and frying. Currently， the harvesting period is autumn， followed by sun-drying or low-heat drying， with processing methods including cleaning， stir-frying， and stewing. In ancient and modern literature， the records of the properties， functions and indications of Quisqualis Fructus are basically the same， that is， sweet in taste， warm in nature， predominantly non-toxic， belonging to the spleen and stomach meridians. It possesses effects of insecticide， decontamination and invigorating spleen for ascariasis， enterobiasis， abdominal pain due to worm accumulation and infantile malnutrition.The contraindications for use primarily include avoiding consumption by individuals without parasitic infestations， limiting use for those with spleen-stomach deficiency-cold， refraining from drinking hot tea during medication， and avoiding excessive intake. Based on the textual research， it is suggested that the dried mature fruits of Q. indica should be used as the medicinal material for the development of famous classical formulas containing Quisqualis Fructus. Processing methods may be chosen according to prescription requirements， and the raw products is recommended for medicinal use if not specified.

Objective To investigate the safety and feasibility of two-port laparoscopic full layer circular closure of the hernia ring for direct inguinal hernia.Methods Between September 2019 and February 2024,9 cases of pediatric indirect inguinal hernia were found to be accompanied by an occult direct inguinal hernia on the right side during two-port laparoscopic inner ring closure.After completing the high ligation of the indirect hernia under laparoscopic monitoring,the bottom of the direct hernia sac was investigated.The needle was held and inserted sequentially from the 4 o'clock direction,crossing the abdominal wall muscle layer through the peritoneum to the subcutaneous layer,and exited at the 8 o'clock direction.The same method was conducted from the 8 o'clock direction in and at the 12 o'clock direction out,and afterwards from the 12 o'clock direction in and at the 16 o'clock direction out(near the previous 4 o'clock insertion point),followed by knotting and closure of the hernia ring.Results Postoperative diagnosis indicated 3 cases of Pantalon hernia(right indirect hernia+right direct hernia)and 6 cases of left indirect hernia+right direct hernia.No extraperitoneal lipoma was found outside the hernia sac.Two-port laparoscopic high ligation of the indirect hernia and laparoscopic circular closure through muscle layer to subcutaneous layer of abdominal wall around the hernia ring was carried out.The operation time was(32.5±3.5)min,and blood loss was less than 1 ml.No intraoperative complications were seen.All the patients were discharged within 6 h after surgery and followed up for 5-13 months(mean,8 months),with 3 cases followed up for more than 12 months.No complications such as incision infection,recurrent hernia,hydrocele,iatrogenic cryptorchidism or testicular atrophy was found.Ultrasound examination of the direct hernia triangular area showed uniform thickness of the abdominal wall and no localized defects observed.Conclusions Laparoscopic circular closure through muscle layer to subcutaneous layer of abdominal wall around the hernia ring is safe and feasible.This procedure supplements the pediatric direct inguinal hernia repair procedure by suturing and closing both peritoneum and abdominal wall muscle layer of direct hernia defect without changing the normal anatomical position of the umbilical fold.

Objectives:To investigate the effect of non-optimal temperature exposure during pregnancy on the risk for preterm birth and identify the susceptible exposure window. At the same time, the interaction between non-optimal temperature and pollutants exposure during pregnancy on preterm birth was analyzed, in order to provide strong clues for the influence of non-optimal temperature exposure during pregnancy on the risk for preterm birth.Methods:A total of 1 852 pregnant women were recruited from September 2021 to June 2023 in Fujian Provincial Maternal and Child Health Care Center. Questionnaire survey was conducted, and their health records were analyzed. The permanent address of each pregnant woman was matched with Fifth Generation European Centre for Medium-Range Weather Forecasts Atmospheric Reanalysis of the Global Climate and a geo-statistical combination model based on satellite remote sensing data collection, then follow-up for pregnancy outcome was conducted. Distributed lag nonlinear model was used to assess the association between exposure to non-optimal temperature during pregnancy and the risk for preterm birth and a multiplicative interaction model was used to assess the interaction between exposure to pollutants and non-optimal temperatures during pregnancy on the risk for preterm birth.Results:After adjusting for potential confounders such as maternal age, occupation, Gross Domestic Product of the region, pre-pregnancy preconception BMI, newborn sex, the weekly susceptibility windows of extreme low temperature ( P1, P3, P5) were week 1-22 , and the weekly susceptibility windows of extreme high temperature ( P95, P97, P99) were week 27 and week 32-36. Extreme low temperature [ P1 ( OR=1.147, 95% CI: 1.041-1.265), P5 ( OR=1.284, 95% CI: 1.035-1.501)] and extreme high temperature [ P97 ( OR=1.146, 95% CI: 1.039-1.263), P99 ( OR=1.216, 95% CI: 1.099-1.345)] exhibited multiplicative interaction with PM 2.5. Conclusions:Exposure to non-optimal temperature during pregnancy was associated with an increased risk for preterm birth. The susceptible exposure windows of extreme low temperature were mainly in early and mid-pregnancy, and the susceptible exposure windows of extreme high temperature were mainly in late-pregnancy. Exposure to non-optimal temperatures and pollutants during pregnancy was associated with an increased risk for preterm birth.

Renal cell carcinoma in a transplanted kidney is rare, and partial nephrectomy in transplanted kidney is even more uncommon. A patient with papillary transplanted renal cell carcinoma who underwent partial nephrectomy was reported. The patient was admitted to the hospital due to the discovery of transplanted kidney mass, and the enhanced examination of CTU found a lesion in the upper pole of the transplanted kidney in the right iliac fossa, which may be renal cancer, with a diameter of about 2 cm. After open partial nephrectomy of the transplanted kidney, the postoperative pathology showed that the tumor was papillary renal cell carcinoma. The antirejection drugs were used after surgery. During the follow-up period of 16 months, there was no recurrence of transplanted kidney tumor.

As the understanding of the pathogenic mechanisms of gastric cancer deepens and the identification of gastric cancer driver genes advances,drugs targeting gastric cancer driver genes have been applied in clinical practice.Among them,trastuzumab,as the first targeted drug for gastric cancer,effectively inhibits the proliferation and metastasis of tumor cells by targeting overexpressed human epidermal growth factor receptor 2(HER2).Trastuzumab has become the standard treatment for HER2-positive gastric cancer patients.Ramucirumab,on the other hand,inhibits tumor angiogenesis by targeting vascular endothelial growth factor receptor 2(VEGFR2)and has been used as second-line therapy for advanced gastric cancer patients.In addition,bemarituzumab targets overexpressed fibroblast growth factor receptor 2(FGFR2),while zolbetuximab targets overexpressed claudin 18.2(CLDN18.2),significantly extending progression-free survival and overall survival in patients with gastric cancer in clinical trials.This article reviews the roles of tumor driver genes in the progression of gastric cancer,and the treatment strategies for gastric cancer primarily based on targeting HER2,VEGF,FGFR2,CLDN18.2 and MET.This provides a reference for clinical application of targeted therapy for gastric cancer.

Objective To explore the medium and long term curative effect of laparoscopic treatment of incarcerated indirect inguinal hernia and summarize the experience of laparoscopic treatment and the characteristics of incarcerated indirect inguinal hernia.Methods A retrospective summary was made on clinical data of 170 children with incarcerated hernia who underwent laparoscopic surgery between January 2016 to February 2024,including 109 boys and 61 girls.The patient's age ranged from 11 days to 11 years old,with a median of 8 months and 27 days.There were 88 cases of right incarcerated hernia and 82 cases of left incarcerated hernia.The incarcerating time (from onset to surgery) was 0.5-360 h,with a median time of 24 h.Results The surgical time was 11-191 min (mean,51.9±29.5 min).Conversion to open surgery was required in 20 cases,in which 14 cases were engaged through the inguinal region for reduction of incarcerated organ and removal of necrotic organ,and 6 cases were treated through umbilical incisions (4 cases of intestinal resection and anastomosis and 2 cases of ileal repair).Most of incarcerated organs among them were small intestine (ileum,84 cases),followed by the ovaries and fallopian tubes (53 cases),and ileocecal region (15 cases),as well as the greater momentum (11 cases).During the surgery,148 cases underwent manual reduction through laparoscopic surgery,14 cases underwent open inguinal region reduction,and 8 cases underwent self-reduction.There were 5 cases ( 2.9％) of small intestinal necrosis,3 cases (1.8％) of greater omentum necrosis,2 cases (1.2％) of small intestine perforation,2 cases (1.2％) of small intestine sarcoplasmic layer damage,2 cases (1.2％) of ovarian fallopian tube necrosis,and 1 case of colonic seromuscular layer damage.The intraoperative exploration revealed 109 cases ( 64.1％) of contralateral hidden hernia,7 cases ( 4.1％) of cryptorchidism,7 cases (4.1％) of umbilical hernia,1 case (0.6％) of Meckel' s diverticulum,and 1 case (0.6％) of ovarian cyst.Intestinal incarceration was seen in 106 cases,with 32 cases (30.2％) showing vomiting symptoms before surgery.Among them,all the 7 cases of necrosis or perforation of incarcerated intestinal tract had vomiting,2 out of 3 cases of damage to the seromuscular layer of incarcerated intestinal tract had vomiting,41.2％ cases (7/17) of blue purple incarcerated intestinal tract had vomiting,and 20.3％ cases (16/79) of incarcerated intestinal tract with fair blood supply had vomiting.The hospital stay was 1-11 d ( median,1 d).Follow-up period ranged from 4 months to 8 years and 5 months,with a median of 4 years and 11 months.Among them,51 cases were less than 3 years,38 cases were between 3 and 5 years,and 81 cases were over 5 years.Recurrence was seen in 2 cases (1.2％).One patient (0.6％) suffered from inguinal incision infection,and there were no complications such as intestinal obstruction or iatrogenic cryptorchidism.Conclusions Laparoscopic treatment of incarcerated indirect inguinal hernia has good medium and long term curative effect.During the surgery,it is necessary to consider the difficulty of hernia reduction and the blood supply of incarcerated organ for timely conversion to open surgery.Once a child with incarcerated hernia has vomiting symptoms before surgery,it indicates blood flow of incarcerated intestinal tract is affected,which requires a timely surgical treatment.

Objective·To establish a transgenic zebrafish line Tg(amh:mCherry)for studying gonadal development and related diseases,and to trace and analyze the developmental process of zebrafish gonads.Methods·A recombinant transgenic expression vector pTol2-amh-mCherry was constructed by using the upstream promoter sequence of the zebrafish anti-Müllerian hormone(amh)gene coding region and the gene coding sequence of the red fluorescent protein,and was validated by using Sanger sequencing.The recombinant transgenic expression vector and mRNA of Tol2 transposase were co-microinjected into zebrafish embryos,and fluorescent zebrafish were selected by using fluorescence microscope to screen for a stable inherited transgenic zebrafish line Tg(amh:mCherry).In situ hybridization was used to detect whether the location of the fluorescence signals was consistent with the location of endogenous expression of amh.The red fluorescence of transgenic zebrafish from generation F3 was observed by fluorescence microscopy,and the process of gonadal development was tracked and analyzed.Results·The recombinant transgenic expression vector pTol2-amh-mCherry was successfully constructed,and a stable inherited F3 generation transgenic zebrafish line Tg(amh:mCherry)was successfully established.The results of in situ hybridization showed that the location of the red fluorescence signals in the transgenic zebrafish Tg(amh:mCherry)was consistent with the location of endogenous expression of amh.Through observation and analysis of the fluorescence of transgenic zebrafish from F3 generation,five developmental patterns of zebrafish gonads were found.Conclusion·The successful construction of Tg(amh:mCherry)transgenic zebrafish line facilitates the tracer analysis of zebrafish gonadal development,which provides a better experimental model for the study of gonad-related diseases.
