Esophageal carcinoma is a malignant disease with a high incidence rate and poor prognosis. The mitochondrial apoptosis pathway plays a pivotal role in the regulation of cell death and has become a focal point in current cancer therapeutics research. Various active components from traditional Chinese medicine （TCM） can target the mitochondrial apoptosis pathway to inhibit esophageal carcinoma， presenting as potential therapeutic agents for this disease. This paper summarizes relevant research on the inhibition of esophageal carcinoma by active components in TCM via targeting the mitochondrial apoptosis pathway. It has been found that flavonoids （casticin， icariin， luteolin， kaempferol， hesperetin， deguelin， etc.）， terpenoids （oridonin， Jaridonin， artesunate， ethyl acetate fraction of pleurotus ferulatus triterpenoid， etc.）， alkaloids （matrine， swainsonine， etc.）， polyphenols （curcumin， epigallocatechin-3-gallate， corilagin， etc.）， steroids （α-hederin， polyphyllin Ⅵ， etc.）， phenols （optimized scorpion venom peptide CT-K3K7， gecko active polypeptide， etc.）， volatile oils （cinnamaldehyde， α -asarone， etc.） and other active components from TCM can target the intrinsic mitochondrial apoptosis pathway， induce apoptosis in esophageal carcinoma cells， and inhibit their proliferation， invasion and migration by regulating oxidative stress， blocking the cell cycle， regulating signaling pathways such as PI3K/Akt and MAPK.

Objective:To investigate the clinicopathological characteristics and prognostic factors of gastrointestinal stromal tumor (GIST) with initial surgical resection.Methods:The retro-spective cohort study was conducted. The clinicopathological data of 847 GIST patients who under-went initial surgical resection in Tianjin Medical University Cancer Institute & Hospital from January 2011 to December 2020 were collected. There were 405 males and 442 females, aged (60±10)years. Measurement data with normal distribution were represented as Mean± SD, and comparison between groups was conducted using the t test. Measurement data with skewed distribution were represented as M(range). Count data were described as absolute numbers or percentages, and comparison between groups was conducted using the chi-square test. Comparison of ordinal data was conducted using the nonparameter rank sum test. The Kaplan-Meier method was used to calculate survival rates. Univariate analysis was conducted using the Log-rank test. Multivariate analysis was conducted using the COX regression model. Results:(1) Clinicopatholo-gical characteristics. Of 847 patients, the tumor primary location was stomach in 585 cases, jejunum and ileum in 142 cases, duodenum in 76 cases, colorectum in 10 cases, esophagus in 3 cases, and extra-gastrointestinal in 31 cases. There were 13 cases with liver metastasis and 22 cases with abdominal metastasis. The tumor maximum diameter was (7±5)cm, and the number of nuclear divisions was 4(range, 0-60) cells/50 high-power field or 5 mm 2. According to risk classification of National Institutes of Health (NIH), 31 cases were of extremely low risk, 238 cases were of low risk, 213 cases were of moderate risk, 365 cases were of high risk. There were 839 of 847 patients positive for CD117, 788 cases positive for Dog-1, 710 cases positive for CD34, respectively. There were 272 cases with Ki-67 <5%, 214 cases with Ki-67 of 5%- 9%, 198 cases with Ki-67 ≥10%, 163 cases with missing data. R 0 resection was in 814 cases and non-R 0 resection was in 33 cases. (2) Gene testing and postoperative adjuvant therapy of GIST patients. ① Gene testing. Of 847 patients, 424 underwent genetic testing. The proportion of genetic testing was 1.89%(1/53) in 2011, 9.76%(8/82) in 2012, 8.45%(6/71) in 2013, 15.66%(13/83) in 2014, 50.00%(40/80) in 2015, 55.26%(42/76) in 2016, 73.86%(65/88) in 2017, 68.27%(71/104) in 2018, 80.65%(75/93) in 2019, 88.03%(103/117) in 2020, respectively. Of 424 with genetic testing, 338 cases had KIT mutation, 31 cases had PDGFRA mutation, 55 cases were wild type. ② Adjuvant therapy. Of 847 patients, 253 patients underwent postoperative adjuvant therapy. The proportions of postoperative adjuvant therapy were 8.82%(21/238), 41.78%(89/213), 39.18%(143/365) in patients of low risk, moderate risk, high risk. Of 578 patients with moderate to high risk, the proportion of postoperative adjuvant therapy was 15.15%(5/33) in 2011, 14.71%(10/68)in 2012, 22.45%(11/49) in 2013, 29.09%(16/55) in 2014, 41.38%(24/58) in 2015, 46.15%(24/52) in 2016, 32.81%(21/64)in 2017, 60.00%(45/75) in 2018, 60.42%(29/48) in 2019, 61.84%(47/76) in 2020, respectively. Of 253 patients underwent postoperative adjuvant therapy, 247 cases received imatinib had 6 cases received sunitinib. (3) Comparison of clinicopathological characteristics of GIST with non-gastric origin and gastric origin. Of 847 patients, 262 cases had non-gastric origin and 585 cases had gastric origin. There were significant differences in gender, the number of tumor, tumor maximum diameter, Ki-67 index, risk classification of NIH, and R 0 resection between the two groups ( χ2=8.62, 8.40, 12.97, 6.57, Z=-6.15, χ2=17.19, P<0.05). (4) Analysis of influencing factors for recurrence-free survival rate in GIST patients. Results of multivariate analysis showed that the year of initial diagnosis, primary site, tumor maximum diameter, mitotic image, risk classification of NIH, R 0 resection, genetic testing and postoperative adjuvant therapy were independent factors influencing recurrence-free survival rate in GIST patients with initial surgical resection ( hazard ratio=0.58, 0.61, 2.00, 1.71, 5.81, 2.56, 0.65, 0.38, 95% confidence interval as 0.39-0.85, 0.45-0.83, 1.46-2.74, 1.24-2.35, 3.16-10.69, 1.63-4.02, 0.46-0.94, 0.25-0.56, P<0.05). Conclusions:GIST with initial surgical resection is common located in stomach, with high positive rate in CD117 and Dog-1. The number of people undergoing genetic testing and targeted therapy for GIST is increasing year by year. There are significant differ-ences in clinicopathological characteristics between GIST with non-gastric origin and gastric origin. The year of initial diagnosis, primary site, tumor maximum diameter, mitotic image, risk classifica-tion of NIH, R 0 resection, genetic testing and postoperative adjuvant therapy are independent factors influencing recurrence-free survival rate in GIST patients with initial surgical resection.

ObjectiveTo investigate the association between serum interleukin (IL) and liver pathological changes in patients with chronic hepatitis B (CHB). MethodsA total of 59 patients with CHB who were treated in Putuo District Central Hospital of Shanghai from February 2018 to February 2019 were enrolled as subjects, and liver biopsy was performed for all patients. According to the degree of liver inflammation, the patients were divided into mild inflammation (G1-G2) group and severe inflammation (G3-G4) group, and according to the degree of liver fibrosis, the patients were divided into mild fibrosis (S0-S2) group and severe fibrosis (S3-S4) group. Serum liver function parameters, blood lipids, interleukin-2 (IL-2), interleukin-6 (IL-6), interleukin-8 (IL-8), and interleukin-10 (IL-10) were measured for all patients. The independent samples t-test was used for comparison of normally distributed continuous data between two groups, and the Wilcoxon non-parametric test was used for comparison of non-normally distributed continuous data between two groups; the chi-square test was used for comparison of categorical data between groups. A Spearman correlation analysis was also performed. ResultsThe degree of liver fibrosis increased with the increase in liver inflammation (rs=0.538, P＜0.001). Compared with the mild inflammation group, the severe inflammation group had significantly higher serum levels of alanine aminotransferase ［95.00 (45.00-16925) U/L vs 51.00 (29.00-88.00) U/L, Z=-2.625, P=0.009］, aspartate aminotransferase ［54.50 (34.75-84.50) U/L vs 38.00 (30.00-49.00) U/L, Z=-2.014, P=0.044］, and gamma-glutamyl transpeptidase ［91.00 (56.72-192.25) U/L vs 44.00 (24.00-100.00) U/L, Z=-2.400, P=0.016］. The severe fibrosis group had a significantly higher serum level of high-density lipoprotein than the mild fibrosis group ［0.97 (0.32-1.08) mmol/L vs 1.23 (0.36-1.38) mmol/L, Z=-1.300, P=0.008］. The severe inflammation group had a significantly higher serum level of IL-2 receptor than the mild inflammation group ［704.00(418.00-103800) U/ml vs 436.00(335.00-555.00) U/ml, Z=-3.405, P=0.001］, and the severe fibrosis group had a significantly higher serum level of IL-2 receptor than the mild fibrosis group ［735.00(523.00-890.50) U/ml vs 447.00 (351.50-624.50) U/ml, Z=-5.358, P=0.001］. ConclusionThe degree of liver inflammation is positively correlated with that of liver fibrosis, while the serum level of IL-2 receptor increases with the increase in the degrees of liver inflammation and fibrosis, indicating that IL-2 receptor can reflect the degrees of liver inflammation and fibrosis to some extent.

OBJECTIVE: To explore the genetic etiology for a child with ocular dysplasia. METHODS: Clinical examination was carried out. Medical history of the child was collected. Genomic DNA was extracted from peripheral blood samples. Chromosomal microarray analysis (CMA) was used to detect potential genomic copy number variations. RESULTS: Ultrasonography revealed cataracts in both eyes of the child. MRI showed increased extracranial space, supratentorial ventricular dilatation, reduced white matter volume, increased T2WI signal and a large occipital cisterna. CMA showed that the patient carried a 249 kb microdeletion at Xq25q26.1 region, namely [hg19]arrXq25q26.1 (128 652 372 - 128 901 629)×0. CONCLUSION The child was diagnosed with Lowe syndrome, for which the 249 kb microdeletion at Xq25q26.1 is probably accountable.

Objective To explore the application value of preoperative bedside ultrasound in the surgical operation of primary liver cancer (PLC).Methods Clinical data of 23 patients with PLC in the Second Affiliated Hospital of Guangzhou Medical University from October 2016 to May 2017 were retrospectively analyzed.The informed consents of all patients were obtained and the local ethical committee approval was received.Among 23 patients,15 cases were male and 8 female,aged from 27 to 73 years with a median age of 53 years.Bedside ultrasound examination was performed in the patients.The liver was scanned and examined by Doppler ultrasound via the xiphoid process,the right costal margin and the intercostal space,and the results were compared with the preoperative imaging data.Results All the patients received bedside ultrasound examination within preoprative 24 h.The left,middle and right hepatic venous structures of the second porta could be displayed clearly by the scaning from xiphoid process,and the left hepatic segment where the lesions located could be further displayed.The scan form right costal margin showed the anatomical relationship of primary porta and the anatomy of portal vein.The scan from intercostal space could identify the position of lesions in the right lobe and determine the intrahepatic distribution of middle and right hepatic veins and right portal vein,and their relationship with lesions.The lesions located in segment Ⅱ and Ⅲ of 6 cases,segment Ⅳ of 5 cases,segment Ⅴ of 2 cases,segment Ⅴ and Ⅷ of 3 cases and segment Ⅵ of 7 cases.The findings of preoperative bedside ultrasound was inconsistent with that of preoperative CT and MRI.The operation was aborted in 1 case and operative plan was changed in 1 case.Conclusions Preoperative bedside ultrasound can provide more anatomical information and lesion distribution for liver surgery,which can shorten the intraoperative exploration time and adjust the surgical plan timely.

BACKGROUND:Kidney-tonifying herbs have been reported to promote tendon-bone healing in rabbits after anterior cruciate ligament reconstruction (ACLR). OBJECTIVE:To verify the effects of kidney-tonifying herbs on tendon-bone healing after ACLR. METHODS:Seventy patients with anterior cruciate ligament injury undergoing ACLR were randomly assigned to study group (administration of Liuwei dihuang pil s+celecoxib) and control group (administration of celecoxib alone). Preoperative, postoperative 6-and 12-month assessments of patients by the Lysholm Knee Scoring Scale, International Knee Documentation Committee (IKDC) Subjective Knee Form and MRI imaging were performed. RESULTS AND CONCLUSION:Postoperative Lysholm scores were significantly increased compared with preoperation in the study and control groups (P<0.05), and the scores of sections stair-climbing and instability and total scores of the Lysholm Knee Scoring Scale in the study group were superior to those in the control group (P<0.05). Postoperative IKDC scores were significantly increased compared with pre-operation in the study and control groups (P<0.05), and the scores of section flaccid leg and subjective function and total scores of the IKDC in the study group were superior to the control group (P<0.05). The enlargement rate of middle and proximal parts of grafts was significantly increased in the study group compared with the control group 6 months postoperatively (P<0.05), and the enlargement rate of middle and distal parts of grafts was significantly increased in the study group compared with the control group 12 months postoperatively (P<0.05). The tibial and femoral tunnel enlargement was observed in both groups at 6 and 12 months postoperatively (P<0.05). The enlargement rate of the tibial tunnel was significantly decreased in the study group compared with in the control group (P<0.05). The signal-noise ratio of the femoral end and middle part of grafts in the study group was significantly higher than that in the control group 6 months postoperatively (P<0.01). In contrast, the signal-noise ratio of the femoral end and middle part of grafts in the study group was significantly lower than that in the control group 12 months postoperatively (P<0.05). Our results indicate that kidney-tonifying herbs can improve the tendon-bone healing after ACLR.
