Objective To study the anatomical location and pathology of membranous obstruction of the inferior vena cava(IVC)in Budd-Chiari syndrome(BCS)with research on the etiologic mechanism and pathology.Methods Analysis of 100 normal adults was performed including the gross anatomy of IVC segment from the level of diaphragm up to right atrium.The conventional,microscopic pathologic examination of the biopsy sampling IVC obstruetice mambrane tissue in 70 cases toghther with the complete resected membrane from the radical therapy for 20 cases of BCS,were collected and under investigation.Results The macroscopic examination revealed the obstructive membrane in one case(1%)localizing at the diaphragmatic level,approximately 28 mm,away from the IVC entrance into the right atrium and a newly found valvula was seen on the left lateral wall of the upper part of the hepatic vein orifice.Simultaneously,47% adults showed Eustachiun valve existing in IVC near the entrance to right atrium.Microscopy confirmed all the forementioned membranes consisting of vascular valvular structures.Among them(21/70),30% showed additional organized thrombus formations,and 9%(6/70)with a few amount of inflammatory cellular infiltrations.The total intact resection membrane was continuous with the vascular wall under microscopic examination.Conclusions The first newly report of the existence of a special valvula at the diaphragmatic level of IVC reveals the possibility of high correlation with the occurance of IVC membranous obstruction type in BCS.

Objective To explore the expressions and clinical significance of epidermal growth factor receptor (EGFR),COOH-terminus tensin-like molecule (CTEN)and epithelial cadherin (E-cad)in non-small cell lung cancer (NSCLC).Methods The expressions of EGFR,CTEN and E-cad in 36 cases of normal lung tissue and 82 cases of NSCLC tissues were observed with immunohistochemical SP method and their correlation with NSCLC invasion,metastasis and prognosis was analyzed.Results The positive rate of EGFR,CTEN and E-cad was 58.5% (48/82),69.5% (57/82)and 28.1% (23/82)in 82 cases of lung cancer,while 13.9% (5/36),0.0% (0/36)and 100% (36/36)in normal tissues;the differences were all significant (P<0.05).EGFR,CTEN and E-cad expressions in NSCLC tissues were significantly correlated with tumor differentiation,TNM stage and lymph node metastasis (P<0 .0 5 ).The expressions of EGFR and CTEN were correlated with each other in NSCLC (r=0 .5 3 0 , P<0.001),while the expressions of EGFR and CTEN were correlated with that of E-cad (r=0.499,P<0.001;r=0.333,P=0.001 ).Multivariate Cox regression analysis showed that CTEN expression in NSCLC was an independent prognostic factor (P<0.05 ).Conclusion EGFR,CTEN and E-cad may play a role in the development,invasion and metastasis of NSCLC and have some significance in predicting the prognosis of NSCLC.

ObjectiveTo analyze the relationship between expressions of Indoleamine 2,3-dioxygenase (IDO) and B7-H1 with clinico-pathological features and their prognostic significance in pancreatic cancer (PC).Method95 patients who underwent radical pancreaticoduodenectomy for PC were studied.The IDO and B7-H1 expressions in tissue specimens were determined by immunohistochemistry.ResultsIDO and B7-H1 expressions were higher in pancreatic carcinoma tissues than in normal pancreatic tissues (P＜0.05).IDO and B7-H1 expressions positively and significantly correlated with pathological grades and tumour-node-metastasis (TNM) stages (P＜0.05).They were prognostic of poor cancer-specific survival.After adjusting by the Cox proportional hazards regression models (P＜0.05),only a combined IDO/B7-H1 expression served as an independent prognostic marker.ConclusionsIDO and B7-H1 were expressed in PC,and they were important markers for malignant progression of PC.A combined IDO/B7-H1 expression served as an independent prognostic marker for PC.

In order to investigate the species and categorization of Gasterophilus in Ili horse.We analysised the COI gene of the identified Gasterophilus dominant species and constructed NJ phylogenetic tree in the study.The results showed that infection rate was 100％ in total of 16 775 the third phase Gasterophilus instar larvae.Four Gasterophilus species were identified,and showed serious mix infections.Dominant species were Gasterophilus nasalis,its relative dominance were 53.17％,and prefer to live in the cardia,others to irregular live in the pylorus of the horses.COI gene homology of GasterophiIus nasalis,Gasterophilus intestinalis,Gasterophilus pecorum,Gasterophilus haemorrhoidalis (GenBank Accession No.:GU265752.1,KR230402.1,KU578262.1,KT946620.1) were 99％,99％,99％ and 100％ respectively.Phylogenetic analysis results showed that the data were clustered with the Gasterophilus app.which publshed on the GenBank.G.intestinalis and G.haemorrhoidalis cluster together first,and then cluster with G.nasalis,at last all three kinds of Gasterophilus cluster with G.pecorum.When the COI gene is the target,in-group and out-group of the Gasterophilus can forms an independent evolutionary branch.This study provides useful parameters for the classification of Gasterophilus.

Objective To observe the clinical effects of magnified pedicle subtraction osteotomy (mPSO) via the posterior approach combined with biomimetic bone graft fusion and internal fixation for the treatment of thoracolumbar Kummell's disease and kyphosis.Methods A total of 11 patients with thoracolumbar Kummell's disease and kyphosis deformity were treated at our department from March 2012 to June 2016.They all underwent mPSO via the posterior approach combined with biomimetic bone graft fusion and internal fixation.They were 3 men and 8 women with an average age of 61.2 years.The clinical effects were evaluated according to visual analogue scale (VAS),Japanese Orthopaedic Association (JOA) scoring,American Spinal Injury Association (ASIA) grading,cobb angle correction and rate of bone graft fusion at preoperation and 2 weeks,1,3,6 and 12 months after operation.Results All the patients were followed up for an average of 11.4 months (from 10 to 13 months).The VAS scores (2.1 ±0.5 points and 1.1 ±0.2 points),JOA scores (23.6 ±3.8 points and 25.5 ±3.2 points) and cobb angles (8.1°± 1.5° and 13.8°±2.1°) at 2 weeks after operation and final follow-ups were significantly improved from their preoperative values (8.1 ± 0.6 points,12.1 ± 3.6 points and 51.3° ± 9.8°,respectively) (P ＜ 0.05).However,there were no significant differences between 2 weeks after operation and the final follow-up in terms of the above values (P ＞ 0.05).The ASIA grading was improved from preoperative grade C to postoperative grade D in one case,and from preoperative grade D to postoperative grade E in 3 cases.At final follow-ups,bony fusion was observed at all the bone graft sites,with a fusion rate of 100％.Conclusion mPSO via the posterior approach combined with biomimetic bone graft fusion and internal fixation is a good treatment for patients with thoracolumbar Kummell's disease and kyphosis deformity.

Objectives:To investigate the effect of body mass index(BMI)on perioperative and long-term prognosis of patients with severe aortic stenosis(AS)after transcatheter aortic valve replacement(TAVR). Methods:This retrospective study imcluded 180 patients with severe AS who received TAVR in Fujian Provincial Hospital from January 2019 to January 2022.According to the BMI,patients were divided into four groups:low weight group(BMI<18.5 kg/m2,n=23),normal weight group(18.5 kg/m2≤BMI<24.0 kg/m2,n=65),overweight group(24.0 kg/m2≤BMI<28.0 kg/m2,n=57),obesity group(BMI≥28.0 kg/m2,n=35).The general clinical characteristics,imaging parameters,perioperative indexes,all-cause death and the incidence of other adverse cardiac events during(18.0±6.8)months follow-up were compared among different groups.Risk factors for the perioperative complications and long-term outcomes of TAVR were evaluated. Results:The prevalence of hypertension and diabetes,left ventricular end-diastolic diameter,ventricular septal thickness and left ventricular posterior wall thickness were significantly higher in the obese group than in normal weight group(all P<0.05).The level of prealbumin in low weight group was lower than in normal weight group(P<0.05).The total perioperative complications in low weight group were higher than in normal weight group(60.9%vs.12.3%,P=0.042).During(18.0±6.8)months follow-up,the incidence of all-cause death in the low weight group was significantly higher than that in normal weight group,overweight group and obese group(17.4%vs.4.6%vs.3.5%vs.5.7%,P=0.003).Kaplan-Meier survival analysis evidenced higher mortality rate in low weight group at 18 months after TAVR(log-rank P<0.01).Multivariate Cox regression analysis showed that the risk of long-term adverse cardiovascular events was significantly higher in low weight group than in normal weight group(HR=7.633,95%CI:1.012-57.564,P=0.049). Conclusions:Low weight patients with severe AS have a higher incidence of perioperative complications and a poor long-term prognosis.Such patients should appropriately strengthen their nutritional intake and adjust their body weight to normal levels before performing TAVR.

Objective To explore the distribution of pattern elements and target organs in dyslipidemia ai-ming at providing theoretical basis for dyslipidemia diagnosis and treatment in clinical practice.Methods A database matrix including clinical manifestations(containing 89 symptoms,physical signs,tongue and pulse)of 1019 patients with dyslipidemia.Factors were extracted according to initial models and rotated with Varimax,then the factor loading and the score of common factors was calculated.Pattern elements were concluded by the common factors,and the patients were grouped by the score of each pattern ele-ment.Thus the distribution of pattern elements and target organs were assigned according to its score of each group.Results 38 common factors and 14 pattern elements were extracted,from which 6 primary pattern elements were selected, including 3 excessive elements, phlegm(284 cases,25.08%), blood stasis(130 cases,11.48%), and heat(109 cases,9.62%)and 3 deficient elements, qi deficiency (170 cases,15.00%), yang deficiency(164 cases, 14.47%), and yin deficiency(108 cases, 9. 53%).8 target organs were extracted in which the main target included the spleen(508 cases, 40. 38%),lung(269 cases 21.38%), heart(218 cases,17.33%)and liver(190 cases, 5.25%). Conclusions Dyslipidemia in traditional Chinese medicine belongs to deficiency in its root(nature)and excess in branch(manifestation).Excessive manifestations include phlegm, blood stasis and heat, and deficient nature includes qi deficiency,yang deficiency and yin deficiency.The main symptom target(lo-cation)was the spleen,the lung,the heart and the liver.Therefore,the findings suggest that treatment of dyslipidemia in traditional Chinese medicine could rely on resolving phlegm, activating blood, remo-ving heat,tonifying qi,warming yang,and reinforcing yin.Spleen should be considered as the first and foremost organ in the treatment,while the lung,heart,and liver should also be taken into consideration.

To predict the distribution and habitat of Dermacentor nuttallii in Xinjiang and to under-stand its life cycle history.In this study,Maximum Entropy Modeling(MaxEnt)was used to pre-dict the geographical distribution and adaptation area of Dermacentor nuttallii in Xinjiang,and jackknife test and response curve of environmental variables were used to evaluate the environmen-tal factors affecting the distribution of Dermacentor nuttallii.Dermacentor samples were collected randomly based on predicted sites.The species of Dermacentor was identified by the combination of morphological characteristics and molecular biology.The New Zealand white rabbit was the only blood donor,and the life cycle and biological characteristics of the tick were observed and recorded by the method of earmuffs feeding under natural light in the laboratory.The jackknife test and SPSS analysis results showed that the main environmental variables affecting the distribution of suitable areas of Dermacentor nuttallii were average temperature(Bio1),average daily tempera-ture range(Bio2),seasonal temperature change(Bio4),driest month precipitation(Bio14),precip-itation variation coefficient(Bio15).The response curves of major environmental variables showed that Dermacentor nuttallii had the highest presence probability when Bio1 was 15.58 ℃,Bio2 was 6.19 ℃,Bio4 had a coefficient of variation of 1 500,Bio14 had a coefficient of variation of 20 mm,Bio15 had a coefficient of variation of 23.799 and Bio19 was 69 mm.The prediction results showed that the suitable areas of Dermacentor nuttallii in Xinjiang were Tianshan Mountain range in Junggar Basin,Turpan basin in Altai Mountain valley and some areas south of Tianshan Mountain range,accounting for 50.99％of the total area of Xinjiang.Dermacentor were collected from the predicted area according to MaxEnt model and identified as Dermacentor nuttallii by morphologi-cal and molecular biological methods.The full blood stage was 5.31 d,the degeneration stage was 8.19 d,and the degeneration rate reached 95.5％.If the full blood stage was 8.65 d and the degener-ation stage was 12.86 d,the degeneration rate reached 98％.The full blood stage of adult ticks was 6.75 d,the early egg stage of full blood females was 5.86 d,and the spawning stage of full blood fe-males was 12.5 d.The eggs hatched into young ticks after 25.92 d,and the hatching rate reached 90％.Dermacentor nuttallii took 62-107 d to complete a life history,with an average of 86.06 d.The constructed MaxEnt model has high prediction accuracy and accuracy.According to the varia-ble analysis of the main environmental factors,precipitation and temperature are the main environ-mental factors affecting Dermacentor nuttallii.The study of the whole life cycle of Dermacentor nuttallii in Xinjiang provides the basis for establishing the method of artificial breeding of pure species of Dermacentor nuttallii in Xinjiang.
