Esophagogastric variceal bleeding is a common complication and the leading cause of death in advanced liver cirrhosis， and endoscopic variceal ligation （EVL） and endoscopic cyanoacrylate injection （ECI） are commonly used treatment strategies. Thrombocytopenia is one of the most common hematological complications in liver cirrhosis， and patients with severe thrombocytopenia have the potential risk of bleeding， which may affect treatment decision-making by clinicians and endoscopists. This article reviews the evolution of guidelines and clinical research advances regarding EVL/ECI in China and globally， in order to provide a basis for decision making among clinicians.

Objective To investigate the need for and utilization of health services among six Zhiguo ethnic minority groups in Yunnan Province,aiming to provide further evidence for the improvement of healthcare.Methods Using stratified random sampling,1921 individuals from six Zhiguo ethnic minority groups,aged 15 and above,were investigated with a structured questionnaire between August and December 2022.A structured questionnaire was used to collect participants'information on health service needs and utilization.Results Am-ong the surveyed participants,the two-week prevalence rate was found to be 22.54%,while the prevalence rate of chronic diseases was 38.52%.Among the residents,the risk of two-week prevalence was higher for females(OR=1.564),individuals aged≥60 years(OR=1.727),and those who reported poorer health utility value(OR=5.277),while it was lower for residents of Keno(OR=0.470)and Lahu(OR=0.659)ethnicity,as well as those who reported higher EQ-VAS scores(OR=0.446/0.174).Meanwhile,residents aged≥45 years(OR=3.392/7.072)were at higher risk for chronic disease prevalence,while it was lower for Keno ethnicity(OR=0.409),unmarried individuals(OR=0.479),and those with higher education levels(OR=0.629/0.603),higher EQ-VAS scores(OR=0.208)P<0.05.Additionally,among the participants,the treat-ment rate for two-week illness was 14.32%,while the non-treatment rate stood at 36.49%.Furthermore,the one-year hospitalization rate was reported as 19.89%,with a corresponding rate of individuals who needed hospitalization but did not receive it being recorded at 15.86%.Among the residents,the likelihood of treatment for two-week illness was higher for females(OR=1.461)and residents aged≥45 years(OR=1.510/1.560),whereas it was lower for individuals with higher EQ-VAS scores(OR=0.445).The likelihood of hospitalization within one year was also higher for residents aged≥60 years(OR=2.029)and individuals of Nu(OR=1.599),Lisu(OR=1.688),and Keno(OR=1.968)ethnicity,whereas those with high EQ-VAS scores(OR=0.325)had a lower risk(P<0.05).Conclusion In Yunnan Province,the need for healthcare services among six Zhiguo ethnic minority groups in this study is relatively low;however,the high prevalence of chronic diseases raises concerns.The utilization of healthcare services appears to be relatively sufficient,but the utilization of outpatient services still needs to be improved.

Objective To study the effects of Gouteng Jiangya Jieyu Prescription(Uncariae Ramulus cum Uncis,Gastrodiae Rhizoma,Pheretima,Puerariae Lobatae Radix,Salviae Miltiorrhizae Radix et Rhizoma,etc.)on learning and memory ability,hippocampal inflammatory response and autophagy-related protein expression in rats with hypertension complicated with depression(HD).Methods Thirty spontaneously hypertensive rats(SHR)were randomly divided into model group,positive control group(Levamlodipine Besylate 0.45 mg·kg-1+Fluoxetine Hydrochloride 1.80 mg·kg-1)and Gouteng Jiangya Jieyu Prescription high-,medium-and low-dose groups(25.38,12.69,6.34 g·kg-1).Another 6 SD rats were used as blank control group.The SHR rats were intervened by chronic mild unpredictable stress combined with solitary rearing to replicate the HD rat model.At the same time,intragastric administration was given once a day for 6 weeks.The systolic blood pressure and diastolic blood pressure of rat tail artery were measured by non-invasive sphygmomanometer.The learning and memory ability of rats was detected by Morris water maze test.The ultrastructure of hippocampal neurons was observed by transmission electron microscope.The contents of interleukin-1β(IL-1β),IL-18 and IL-10 in hippocampus were detected by ELISA.The expression of autophagy-related proteins Beclin1 and Bcl-2 in hippocampus was detected by immunohistochemistry.The expression of autophagy-related proteins LC3Ⅰ and LC3Ⅱ in hippocampus was detected by Western Blot.Results Compared with the blank control group,the SBP and DBP of the rats in the model group were significantly increased from week 1-6(P＜0.01).The escape latency was significantly prolonged on the third and fourth day(P＜0.01).The first time of crossing the platform was significantly prolonged(P＜0.01),the times of crossing the platform area was significantly reduced(P＜0.05),and the retention time of the platform area was significantly shortened(P＜0.01).The neuronal cell body was obviously swollen,the ridge was destroyed,the nucleus was shrunk,and a large number of autophagosomes appeared;the contents of IL-1β and IL-18 in hippocampus were significantly increased(P＜0.01).The ratio of LC3Ⅱ/LC3Ⅰ protein expression and the expression of Beclin1 protein in hippocampus were significantly up-regulated(P＜0.05,P＜0.01),and the expression of Bcl-2 protein was significantly down-regulated(P＜0.01).Compared with the model group,the SBP of rats in the low-dose group of Gouteng Jiangya Jieyu Prescription was significantly decreased at the weeks 1,3,4,5,6(P＜0.01),and the DBP was significantly decreased at weeks 1,3,4,5(P＜0.05,P＜0.01).The SBP of the rats in the medium-dose group of Gouteng Jiangya Jieyu Prescription was significantly decreased at weeks 1,5,6(P＜0.01),and the DBP was significantly decreased at week 4(P＜0.05).The SBP of rats in the high-dose group of Gouteng Jiangya Jieyu Prescription was significantly decreased in the first week(P＜0.01).The escape latency of rats in the high-and medium-dose groups of Gouteng Jiangya Jieyu Prescription was significantly shortened on the third day(P＜0.05),and the escape latency of rats in the high-and low-dose groups of Gouteng Jiangya Jieyu Prescription was significantly shortened on the fourth day(P＜0.05).The first crossing platform time of rats in the high-,medium-and low-dose groups of Gouteng Jiangya Jieyu Prescription was significantly shortened(P＜0.01).The times of rats crossing the platform area in the medium-and low-dose groups of Gouteng Jiangya Jieyu Prescription were significantly increased(P＜0.05),and the retention time in the platform area was significantly prolonged(P＜0.05).In the administration group,the degree of hippocampal neuron damage was reduced,the nuclear shrinkage was significantly improved,and the autophagosomes were reduced.The contents of pro-inflammatory factors IL-1β and IL-18 in the hippocampus of rats in the high-and medium-dose groups of Gouteng Jiangya Jieyu Prescription were significantly decreased(P＜0.05,P＜0.01).The content of anti-inflammatory factor IL-10 in the hippocampus of rats in the high-dose group of Gouteng Jiangya Jieyu Prescription was significantly increased(P＜0.01).The protein expression ratio of LC3Ⅱ/LC3Ⅰ in hippocampus of high-,medium-and low-dose groups of Gouteng Jiangya Jieyu Prescription was significantly down-regulated(P＜0.01),and the expression of Bcl-2 protein was significantly up-regulated(P＜0.01).The expression of Beclin1 protein in the hippocampus of the high-and medium-dose groups of Gouteng Jiangya Jieyu Prescription was significantly down-regulated(P＜0.05,P＜0.01).Conclusion Gouteng Jiangya Jieyu Prescription can reduce the tail arterial pressure of HD rats,improve their learning and memory ability,and alleviate hippocampal neuronal damage.The mechanism may be related to reducing the release of inflammatory factors,increasing the level of anti-inflammatory factors,and regulating the expression of hippocampal autophagy-related proteins LC3Ⅱ/LC3Ⅰ,Beclin1 and Bcl-2.

Objective To compare the short-term clinical effects of unilateral dual-channel endoscopic discectomy(UBED)and percutaneous endoscopic intervertebral discectomy(PEID)in the treatment of L5S,Lumbar disc herniation,LDH.Methods From January 2019 to January 2021,a total of 57 cases of L5S,LDH treated by UBED or PEID were analyzed retrospectively,including 30 cases in UBED group and 27 cases in PEID group.The operation time,intraoperative fluoroscopy times,postoperative hospitalization days and surgical complications were compared between the two groups.The visual analogue scale(VAS)and oswestry disability index(ODI)were used to compare the postoperative quality of life of the two groups,and the modified MacNab criteria was used to evaluate the clinical efficacy in the last follow-up.Results The operation time of UBED group and PEID group was(75.30±8.44)minutes and(68.37±4.63)minutes,respectively,and the difference between the two groups was statistically significant(P＜0.05).VAS and ODI of 1 week,3 months,1 year and 1.5 years after surgery in 2 groups were significantly decreased compared with those before surgery,with statistical significance(P＜0.05).The VAS score of low back pain in UBED group was higher than that in PEID group[(3.87±1.14)points vs(2.70±0.67)points]at 1 week after surgery(P＜0.05),and there was no significant difference in VAS and ODI at the other time points(P＞0.05).There was no statistical difference in the results of modified MacNab criteria in the last follow-up(P＞0.05).There were 2 cases of dural tear in PEID group,1 case of dural tear in UBED group and 1 case of temporary nerve root injury in PEID group after operation,all of which were cured after symptomatic treatment.Conclusion Compared with PEID,UBED has a longer operation time,more trauma and more obvious low back pain in the short term after operation.The short-term curative effect of the two operations on L5S1 LDH is similar,the incidence of complications is low,and the times of fluoroscopy are few.Both operations are safe and effective.

Objective To evaluate the current situation of radioactive contamination in the soil around a decommissioned uranium mine by combined determination of ²¹⁰Pb and ²¹⁰Po activity concentrations. Methods Soil samples were collected around a decommissioned uranium mine. ²¹⁰Po and the ²¹⁰Pb decay product ²¹⁰Bi were plated on a copper sheet by self-deposition at a constant temperature. Gross α and gross β counts were measured using a low-background α/β counter. The activity concentrations of ²¹⁰Pb and ²¹⁰Po in soil were calculated. The radioactive contamination was evaluated using geological accumulation index. Results The activity concentrations of ²¹⁰Pb and ²¹⁰Po in the soil around the decommissioned uranium mine were 873.7-2315.5 and 956.0-2315 Bq·kg⁻¹, respectively. The activity concentrations of ²¹⁰Pb and ²¹⁰Po in nearby farmland soil were 54.2-257.8 and 59.1-234.5 Bq·kg⁻¹, respectively. Evaluation with the geological accumulation index showed that the level of nearby farmland contamination was 0-2, indicating zero to moderate radioactive contamination of the farmland. Conclusion The relatively high radioactivity around the decommissioned uranium mine requires attention to the transfer, diffusion, and ingestion of the uranium decay products ²¹⁰Pb and ²¹⁰Po in the surrounding soil to avoid radioactive contamination of the environment.
