Objective To investigate the clinical value of Yishen Gujing Kangyan Prescription(with the actions of benefiting the kidneys,consolidating essence and anti-inflammatory,mainly composed of Imperatae Rhizoma,Codonopsis Radix,Corni Fructus,Moutan Cortex,Lycii Fructus,Cuscutae Semen,Dioscoreae Rhizoma,honey-roasted Astragali Radix,Poria,Rehmanniae Radix Praeparata,etc.)in the treatment of lupus nephritis(LN)of qi and yin deficiency type.Methods A total of 116 patients with LN of qi and yin deficiency type were randomly divided into observation group and control group,58 cases in each group.The control group was given conventional western medicine treatment,and the observation group was treated with the combination of Yishen Gujing Kangyan Prescription on the basis of treatment for the control group.Both groups were treated for a period of 6 months.The changes of traditional Chinese medicine(TCM)syndrome scores,renal function parameters,immune function indicators,serum interleukin 18(IL-18),homocysteine(Hcy),transforming growth factor β1(TGF-β1),cystatin C(Cys C)levels in the two groups were observed before and after the treatment.After treatment,the clinical efficacy and the negative-conversion of anti-double-stranded DNA(ds-DNA)antibody were compared between the two groups.Results(1)After 6 months of treatment,the total effective rate of the observation group was 94.83%(55/58),and that of the control group was 75.86%(44/58).The intergroup comparison showed that the therapeutic effect of the observation group was significantly superior to that of the control group(χ2 = 5.453,P＜0.05).(2)After treatment,the scores of primary symptoms(edema,fatigue)and secondary symptoms(lumbar and knee soreness,loose stools)in the two groups were lower than those before treatment(P＜0.05),and the effect on lowering the scores in the observation group was significantly superior to that in the control group(P＜0.01).(3)After treatment,the levels of renal function parameters of blood urea nitrogen(BUN),serum creatinine(Scr),and 24-hour urine protein quantification of the two groups were all lower than those before treatment(P＜0.05),and the effect on lowering renal function parameters in the observation group was significantly superior to that in the control group(P＜0.01).(4)After treatment,serum IL-18,TGF-β1,Hcy and Cys C levels of the two groups of patients were all reduced compared with those before treatment(P＜0.05),and the effect on lowering the levels of inflammatory factors and fibrosis parameters in the observation group was significantly superior to that in the control group(P＜0.01).(5)After treatment,the levels of immune function indicators of T cell subsets CD4+,CD4+/CD8+ and complement C3 in the two groups were increased compared with those before treatment(P＜0.05),and the increase in the observation group was significantly superior to that in the control group,and the differences were all statistically significant(P＜0.05 or P＜0.01).(6)The negative-conversion rate of anti-ds-DNA antibody in the observation group was 77.59%(45/58),which was significantly higher than that in the control group(55.17%,32/58),and the difference was statistically significant between the two groups(P＜0.05).Conclusion For the treatment of patients with LN of qi and yin deficiency type,Yishen Gujing Kangyan Prescription exerts synergistic effect on reducing inflammatory response,regulating immune function,promoting the recovery of renal function,and enhancing clinical efficacy.

Objective To evaluate the value of high-throughput sequencing(HTS)data reanalysis that does not include ERBB2 copy number variation(CNV)analysis,in identifying ERBB2 amplification in patients with colorectal cancer.Methods The HTS data of 252 cases of colorectal cancer diagnosed by pathological biopsy who received peripheral blood cfDNA HTS detection samples were retrospectively analyzed.According to the HTS data of ERBB2 non-amplified samples judged by immunohistochemistry(IHC)and/or fluorescence in situ hybridization(FISH),the number of chromosome 17(Chr17)reads in the total number of reads was calculated the range of the ratio was initially determined as the threshold for prompting ERBB2 amplification.Suspected positive samples were screened according to thresholds and verified by digital PCR,IHC and FISH.Results The proportion of the number of Chr17 reads accounts for the number of total reads in the 89 cases of ERBB2 non-amplified samples determined by IHC and/or FISH ranged from 0.188 to 0.299(0.239±0.192).Using 0.298(1.25 times the mean)as the threshold indicating ERBB2 amplification,the data of 163 samples were analyzed,of which 7 cases were suspected to be positive,and the ratio ranged from 0.302 to 0.853.Among them,5 cases were determined to be positive by IHC and/or FISH,and 6 cases were confirmed to be positive by digital PCR.The ratio of the number of Chr17 reads to the number of total reads was positively correlated with the ratio of ERBB2/EIF2C1,and the correlation was good(r2=0.909).Conclusion The high-throughput sequencing data that does not cover the ERBB2 CNV analysis has a certain hint value for ERBB2 amplification in patients with colorectal cancer.

The Piezo protein is a non-selective mechanosensitive cation channel that exhibits sensitivity to mechanical stimuli such as pressure and shear stress. It converts mechanical signals into bioelectric activity within cells, thus triggering specific biological responses. In the digestive system, Piezo protein plays a crucial role in maintaining normal physiological activities, including digestion, absorption, metabolic regulation, and immune modulation. However, dysregulation in Piezo protein expression may lead to the occurrence of several pathological conditions, including visceral hypersensitivity, impairment of intestinal mucosal barrier function, and immune inflammation.Therefore, conducting a comprehensive review of the physiological functions and pathological roles of Piezo protein in the digestive system is of paramount importance. In this review, we systematically summarize the structural and dynamic characteristics of Piezo protein, its expression patterns, and physiological functions in the digestive system. We particularly focus on elucidating the mechanisms of action of Piezo protein in digestive system tumor diseases, inflammatory diseases, fibrotic diseases, and functional disorders. Through the integration of the latest research findings, we have observed that Piezo protein plays a crucial role in the pathogenesis of various digestive system diseases. There exist intricate interactions between Piezo protein and multiple phenotypes of digestive system tumors such as proliferation, apoptosis, and metastasis. In inflammatory diseases, Piezo protein promotes intestinal immune responses and pancreatic trypsinogen activation, contributing to the development of ulcerative colitis, Crohn’s disease, and pancreatitis. Additionally, Piezo1, through pathways involving co-action with the TRPV4 ion channel, facilitates neutrophil recruitment and suppresses HIF-1α ubiquitination, thereby mediating organ fibrosis in organs like the liver and pancreas. Moreover, Piezo protein regulation by gut microbiota or factors like age and gender can result in increased or decreased visceral sensitivity, and alterations in intestinal mucosal barrier structure and permeability, which are closely associated with functional disorders like irritable bowel sydrome (IBS) and functional consitipaction (FC). A thorough exploration of Piezo protein as a potential therapeutic target in digestive system diseases can provide a scientific basis and theoretical support for future clinical diagnosis and treatment strategies.

Objective To develop a portable collection device of human exhaled breath condensate(EBC)based on natural breathing to meet the needs for rapid screening of human respiratory tract(especially lower respiratory tract)infections.Methods The device consisted of a refrigeration unit,a heat dissipation unit and a condensation unit.The refrigeration unit adopted a TES1-7102 thermoelectric Peltier cooler semiconductor as the refrigeration element;the heat dissipation unit was composed of a high thermal conductivity aluminum heat sink and a high-speed brushless cooling fan;the condensation unit was made up of a cold guide plate and a condenser,in which the cold guide plate was made of thin sheet of aluminum alloy,and the condenser was prepared by 3D printing technology and made of hydrophobic polylactic acid,with primary and secondary 2-stage guide grooves and an ultra-thin condensing surface.The performance of the device was verified in terms of cooling,thermal conductivity,condensation and human EBC collection and content analysis.Results Performance analysis showed that after refrigeration began the temperature difference between the condenser surface and the exhaled gas met the requirements of the condenser,and no obvious thermal resistance was found on the condensing surface so that large droplets could be formed rapidly and then be collected after the gas-liquid phase change of the exhaled gas on the condensing surface.Human EBC collection and content analysis indicated the device realized home self-collection of EBCs from people of all ages,and the concentrations of interleukins,C-reactive protein and other inflammation-related indexes and the pH value of the collected EBC samples were all correlated with respiratory infections in the subjects.Conclusion The device developed with easy operation avoids the discomfort of blowing collection and the risk of saliva contamination,and is worthy promoting for rapid diagnosis and dynamic monitoring of respiratory tract infection and other related diseases.[Chinese Medical Equipment Journal,2024,45(8):32-37]

Objective To compare the clinical efficacy of the posterior hemipelvectomy of the greater trochanter approach with the standard Kocher-Langenbeck(K-L)approach in the treatment of posterior acetabulum wall fractures and to explore a more optimal approach for the treatment of posterior acetabulum wall fractures.Methods Total of 26 patients with posterior ac-etabulum wall fractures were retrospectively analysed and divided into two groups:the posterior hemipelvectomy of the greater trochanter group(test group)and the standard K-L approach group(control group).In the test group,there were 24 patients including 16 males and 8 females with an average age of(42.00±4.52)years old,the time of injury to surgery was(6.75±1.15)d.In the control group,there were 23 patients including 16 males and 7 females with an average age of(41.00±5.82)years old,the time of injury to surgery was(7.09±1.20)days.The total hospital stay,length of incision,operation time,intraoperative bleeding,postoperative drainage,discharge,fracture reduction quality(Matta criteria),hip abduction muscle strength,hip func-tion(Merle d'Aubigne-Postel score),postoperative complications and the incidence of ectopic ossification were compared.Results All cases were followed up for 6 months.There was no significant difference in incision length,intraoperative bleeding and postoperative drainage between two groups(P＞0.05).However,the operation time of the test group was shorter than that of the control group(P＜0.05).There was no statistically significant difference in fracture reduction and hip function between two groups(P＞0.05).The hip abduction muscle strength of test group was better than that of control group(P＜0.05).In addition,there was no significant difference in the incidence of postoperative complications and heterotopic ossification between two groups(P＞0.05).Conclusion Compared with the standard K-L approach,the posterior hemipelvectomy of the greater trochanter approach can shorten the operative time,has better recovery of the postoperative hip abduction muscle strength,ex-poses the view of the fracture involving the more comminuted posterior acetabulum wall or the fracture of the roof of the socket,improved the rate of fracture anatomical repositioning,provides a new idea for the clinical treatment of posterior acetabulum wall fractures,and allows patients to perform functional exercises at an early stage.

Objective:To analyze the clinical features and laboratory indicators in patients with solid malignant tumor-associated venous thromboembolism(Ta-VTE),and to study the risk factors for Ta-VTE.Methods:The hospitalized patients with VTE in Guizhou Provincial People's Hospital from January to December 2020 were enrolled,and they were divided into Ta-VTE group and pure VTE group based on the presence or absence of solid malignant tumor.The differences in clinical data and laboratory indicators between the two groups were analyzed,and the indicators with significant differences were included in logistic regression model to analyze the risk factors of Ta-VTE.Results:A total of 288 patients with VTE were included in this study,including 64 cases in Ta-VTE group and 224 cases in pure VTE group,respectively.There were significant differences in the following indexes between the two groups,including the hospitalization time(14.20±15.29 d vs 10.05±6.90 d,t=3.112,P=0.002),pain(35.94％vs 65.18％,x2=17.554,P=0.000),recent surgery(75.00％vs 37.50％,X2=28.196,P=0.000),D-dimer[2.8(0.92,7.55)μg/ml vs 5.69(2.25,13.91)μg/ml,Z=-2.710,P=0.007],PLR[198.59(139.54,312.16)vs 149.76(114.08,233.66),Z=-2.924,P=0.003]and TBIL[10.90(7.63,15.68)μmol/Lvs 12.90(9.33,18.28)μmol/L,Z=-2.066,P=0.039].There was no significant difference in the other indicators(P＞0.05).The result of multivariate logistic regression analysis showed that elevated PLR(OR=1.003,95％CI:1.000-1.006,P=0.027),recent surgery(OR=4.312,95％CI:2.093-8.885,P=0.000)and prolonged hospitalization(OR=1.037,95％CI:1.002-1.074,P=0.038)were independent risk factors for Ta-VTE.However,pain(OR=0.274,95％CI:0.133-0.564,P=0.000)was a protective factor.Conclusion:Elevated PLR level,recent surgery and prolonged hospital stay are independent risk factors for Ta-VTE patients,and rational use of these indicators is helpful for the clinical diagnosis and treatment of Ta-VTE patients.

Modern Chinese medicine studies have confirmed that the interaction between traditional Chinese medicine(TCM)and intestinal flora is the key to the treatment of diseases with tradi-tional Chinese medicine.This interplay includes such activities as:traditional Chinese medicine can be metabolized by intestinal flora into effective components with different biological activities from its precursors;TCM chemicals improve the composition of gut microbiota,consequently ameliorating its dysfunction as well as associated pathological conditions;and gut microbiota mediate the interactions between the multiple chemicals in TCM.There-fore,it becomes an important way to understand the modern sci-entific connotation of traditional Chinese medicine theory to study the pharmacological mechanism of the efficacy of traditional Chi-nese medicine by targeting Gut microbiota.

OBJECTIVE: To compare the short-term clinical efficacy of SuperCap approach and direct anterior approach in total hip arthroplasty. METHODS: Clinical data of 70 patients who underwent minimally invasive SuperCap approach and DAA THA in January 2016 to June 2017 were retrospective analyzed. These patients were divided into two groups:SuperCap approach group(SuperCap group) and direct anterior approach group(DAA group). There were 15 males and 15 females in SuperCap group, aged from 45 to 71 years old, and the follow-up time ranged from 24 to 30 months. There were 24 males and 16 females in Group B, aged from 51 to 76 years and the follow-up time ranged from 24 to 36 months. Hemoglobin level of the 3rd day after operation, transfusion rate, acetabular abduction angle, anteversion angle and creatine kinase level of the 3rd day after operation, Harris score of 3 months and the last time, VAS score of 1 week and the last time were recorded and compared. Complications were recorded at the final follow-up. RESULTS: All patients were followed up, the follow-up time of SuperCap group ranged from 24 to 30 months, that of DAA group ranged from 24 to 36 months. No significant differences were found in hemoglobin level on the 3rd day after operation, transfusion rate, Harris score or VAS score between two group (P>0.05). There was no significant difference in Harris score between 3 months after operation and the final follow-up in both groups (P>0.05). There were no significant difference in VAS scores of 6 weeks after operation and on the final follow-up neither(P>0.05). The level of creatine kinase in SuperCap group was significant lower than that in DAA group(P<0.05). Until the final follow-up, there was no significant difference in the incidence of complications between the two groups(P>0.05). CONCLUSION The clinical effect of minimally invasive SuperCap approach after total hip arthroplasty is comparable to that of DAA approach with less soft tissue injury. Patients can recover rapidly after operation and it is a safe and effective surgical approach for surgeons with short learning curve.
