Objective:To explore the characteristics of SLCO1B1/ SLCO1B3 gene variants among children with Rotor syndrome (RS). Methods:Four children who were admitted to the Department of Hepatology of Hunan Children′s Hospital between January 2019 and January 2022 were selected as the study subjects. Trio-whole exome sequencing was carried out for the four families, and gel electrophoresis was used to verify an insertional variant of long-interspersed element-1 (LINE-1).Results:Genetic testing has identified three variants of the SLCO1B1 gene, including c. 1738C>T (p.R580*), c. 757C>T (p.R253*) and c. 1622A>C (p.Q541P), and two variants of the SLCO1B3 gene, including c. 481+ 22insLINE-1 and c. 1747+ 1G>A among the children. Three of them were found to harbor homozygous variants of the SLCO1B1/ SLCO1B3 genes, and one has harbored compound heterozygous variants. Sanger sequencing confirmed the existence of all variants, and gel electrophoresis has confirmed the existence of the LINE-1 insertional variant of about 6 kb within intron 6 of the SLCO1B3 gene in all children. Conclusion:The pathogenesis of the RS among the four children may be attributed to the variants of the SLCO1B1/ SLCO1B3 genes. The LINE-1 insertion variant of the SLCO1B3 gene may be common among Chinese RS patients.

As a common clinical disease, fracture is often accompanied by pain, swelling, bleeding as well as other symptoms and has a high disability rate, even threatening life, seriously endangering patients' physical and psychological health and quality of life. Medical practitioners take many strategies for the treatment of fracture healing, including Traditional Chinese Medicine (TCM). In the early stage of fracture healing, the local fracture is often in a state of hypoxia, accompanied by the expression of hypoxia inducible factor-1α (HIF-1α), which is beneficial to wound healing. Through literature mining, we thought that hypoxia, HIF-1α and downstream factors affected the mechanism of fracture healing, as well as dominated this process. Therefore, we reviewed the local characteristics and related signaling pathways involved in the fracture healing process and summarized the intervention of TCM on these mechanisms, in order to inspirit the new strategy for fracture healing, as well as elaborate on the possible principles of TCM in treating fractures based on the HIF molecular mechanism.

Objective To investigate the protective effect and mechanism of J147 on the injury of human neuroblastoma cells(SH-SY5Y)induced by high glucose(HG).Methods We established HG-induced SH-SY5Y cell injury model.Then SH-SY5Y cells were divided into blank control(Con)group HG group,HG+J147 0.5 μmol/L(HG+J147 0.5)group,HG+J147 1 μmol/L(HG+J147 1)group,HG+J147 2 μmol/L(HG+J147 2)group,HG+PI3K/AKT inhibitor LY294002(LY)10 μmol/L(HG+LY)group,HG+ERK1/2 inhibitor U0126(U0)5 μmol/L(HG+U0)group,HG+J147 2 μmol/L+LY 10 μmol/L(HG+J147 2+LY)group,HG+J147 2 μmol/L+U0 5 μmol/L(HG+J147 2+U0)group.Cell viability was detected by MTS cell proliferation and toxicity detection kit;LDH activity was tested by lactate dehydrogenase kit;morphological changes of SH-SY5Y cells were evaluated by microscope;cell apoptosis was detected by flow cytometry;and apoptosis-related proteins(Bcl-2,Bax)and signaling pathway-related proteins(p-AKT,AKT,p-ERK1/2,ERK1/2,p-CREB,CREB,BDNF)were detected by Western blot.Results Compared with Con group,the cell viability,Bcl-2/Bax ratio,p-AKT/AKT,p-ERK/ERK,p-CREB/CREB and BDNF protein expressions decreased(P<0.01),while LDH activity and apoptosis rate increased in HG group(P<0.01).Compared with HG group,the cell viability,Bcl-2/Bax ratio,p-AKT/AKT,p-ERK/ERK,p-CREB/CREB and BDNF protein expressions increased(P<0.01),while LDH activity and apoptosis rate decreased in HG+J147 2 group(P<0.01).Compared with HG+J147 2 group,the cell viability,Bcl-2/Bax ratio,p-AKT/AKT and BDNF protein expression decreased(P<0.05 or P<0.01),while LDH activity and apoptosis rate increased(P<0.05 or P<0.01),the expression of p-ERK/ERK protein in HG+J147 2+LY group decreased(P<0.05),and the expression of p-CREB/CREB protein in HG+J147 2+U0 group decreased in HG+J147 2+LY and HG+J147 2+U0 groups(P<0.05).Conclusions J147 can alleviate HG-induced SH-SY5Y cell damage,and the mechanism may be related to the activation of PI3K/AKT and ERK1/2 signaling and the reduction of apoptosis.

Results:The quality control data of gastric cancer surgery in Jiangsu Province from 2020 to 2022 were consistently collected and published.The data analysis results show that there was a gradual increase in the percent of patients with stage Ⅰ gastric cancer,reflecting the success efforts of early screening and diagnosis.Laparoscopic surgery showed a steady increase and became the mainstream approach for curative surgery of gastric cancer in Jiangsu Province.The percent of hospital with lymph node dissection≥30 was also increased.Different locations of gastric cancer exhibited specific patterns in the choice of anastomosis methods after curative surgery.The rate of grade 3 or higher complications in laparoscopic gastric cancer surgery was slightly lower than that in open surgery.For patients experiencing complications,their postoperative hospitalization duration and expenditure were significantly higher.Finally,there was a gradual increase in the proportion of hospital choosing to close the mesentery during gastric cancer surgery. Conclusion:The publication of the quality control data of gastric cancer surgery in Jiangsu Province has driven the improvement of gastric cancer surgery standards of China.

Objective To investigate the effect of intrarectal local anesthesia (IRLA) with heated oxybuprocaine gel on pain during transrectal ultrasound guided prostate biopsy (TRUSPB).Methods A total of 150 cases patients who underwent TRUSPB in Huzhou Central Hospital from January to June 2023 were prospectively taken into.The patients were randomly divided into group A (routine group),group B (oxybuprocaine gel for IRLA at room temperature) and group C (oxybuprocaine gel for IRLA at 40℃),with 50 cases in each group.Nurses who were unaware of the anesthesia type used visual analog scale (VAS) to score the pain level of patients at each stage (VAS Ⅰ:when the ultrasound probe was inserted into the rectum;VAS Ⅱ:during the biopsy;VAS Ⅲ:30 minutes after biopsy),and the incidence of complications after biopsy were compared.Results The VAS Ⅱ score of group C was lower than that of group A and group B,and the difference was statistically significant (P<0.05).There was no statistically significant difference (P>0.05) in the VAS Ⅰ,VAS Ⅲ scores,and incidence of complications after biopsy among the three groups.There was no allergic reaction to oxybuprocaine gel.Conclusion In TRUSPB,IRLA with heated oxybuprocaine gel can effectively control pain without increasing incidence of complications.

Prepubertal-type testicular neuroendocrine tumor is a rare neoplasm of low malignant potential, which is classified as germ cell tumors unrelated to germ cell neoplasia in situ, and needs to be differentiated from metastatic neuroendocrine tumor, postpubertal-type testicular neuroendocrine tumor, and testicular seminoma. The clinicopathological and molecular features of a case of prepubertal-type testicular neuroendocrine tumor were reported. The tumour cells were uniform in size and arranged in nested and insular pattern. The tumor was positive for CgA and Syn, and the Ki-67 index was less than 2% by immunostaining. Next-generation sequencing identified no variants of pathogenicity, potential pathogenicity or uncertain significance. The patient was followed without evidence of recurrence and metastasis 56 months after surgery.
