BACKGROUND:Eucommia ulmoides has a certain osteogenic effect,which can promote the proliferation and differentiation of osteoblasts.However,it is unclear whether Eucommia ulmoides has effects on alveolar bone formation and Wnt/β-Catenin signaling pathway. OBJECTIVE:To investigate the mechanism by which Eucommia ulmoides promotes alveolar bone formation in ovariectomized rats based on the Wnt/β-Catenin signaling pathway. METHODS:Sixty female Sprague-Dawley rats were selected and randomly divided into five groups:blank control group,sham-operation group,model group,low-dose group Eucommia ulmoides group,and high-dose Eucommia ulmoides group,with twelve rats in each group.Osteoporosis animal models were constructed by bilateral oophorectomy in the model group and the low-dose and high-dose Eucommia ulmoides groups.The sham-operation group underwent the same method to remove adipose tissue of equal mass around the bilateral ovaries.Three months after surgery,the low-and high-dose Eucommia ulmoides groups were given 2.1 g/kg/d and 4.2 g/kg/d Eucommia ulmoides by gavage,respectively.The sham-operation group and model group were given the same amount of physiological saline by gavage.After 12 weeks of drug intervention,the changes in alveolar bone mass of rats in each group were observed through Micro-CT;hematoxylin-eosin staining was used to observe the pathological structural changes of alveolar bone in rats;enzyme linked immunosorbent assay was used to detect the expression levels of alkaline phosphatase and osteocalcin in the serum of rats;western blot was used to detect the expression levels of β-Catenin and Frizzled9 receptor proteins in the alveolar bone of rats;and real-time fluorescence quantitative PCR was used to detect the expression of osteocalcin,Runt-related transcription factor 2(Runx2),alkaline phosphatase,β-catenin,and frizzled9 mRNAs in alveolar bone tissues of rats. RESULTS AND CONCLUSION:Compared with the blank control group,bone volume fraction,trabecular number,trabecular thickness,and bone mineral density were reduced in the model group(P＜0.05),and trabecular separation was elevated(P＜0.05).Pathological observation showed that the arrangement of trabeculae was disordered and irregular,the trabeculae were thinned or broken,and the marrow cavity was enlarged in the model group,with a significant reduction in bone volume;the level of alkaline phosphatase in the serum was increased(P＜0.05),and the level of osteocalcin was decreased(P＜0.05);mRNA expression of alkaline phosphatase,osteocalcin,Runx2,β-catenin,and frizzled9 were decreased(P＜0.05);protein expression of β-Catenin and Frizzled9 was decreased(P＜0.05).Compared with the model group,the low-and high-dose Eucommia ulmoides groups showed an increase in bone volume fraction,trabecular number,trabecular thickness,and bone mineral density(P＜0.05)and a decrease in trabecular separation(P＜0.05).In the low-and high-dose Eucommia ulmoides groups,bone trabeculae were slightly aligned and thickened,with a significant increase in bone mass.Compared with the model group,the serum level of alkaline phosphatase was reduced(P＜0.05)and the serum level of osteocalcin was elevated(P＜0.05)in the low-and high-dose Eucommia ulmoides groups.Compared with the model group,the mRNA expression of alkaline phosphatase,osteocalcin,Runx2,β-catenin,and frizzled9 were increased in the low-and high-dose Eucommia ulmoides groups(P＜0.05).Compared with the model group,the protein expression of Frizzled9 was increased in the low-dose Eucommia ulmoides group(P＜0.05),while the protein expression of β-Catenin and Frizzled9 was increased in the high-dose Eucommia ulmoides group(P＜0.05).Compared with the low-dose Eucommia ulmoides group,the high-dose Eucommia ulmoides group had a more significant improvement in the above indexes.To conclude,Eucommia ulmoides can effectively promote the alveolar bone formation,and its mechanism of action might be related to the activation of the Wnt/β-catenin signaling pathway.

The areas of S. japonicum-infected snail habitats appeared an average annual reduction of 47.09% in Wuhan City from 2005 to 2023 [AAPC = -47.09%, 95% CI: (-52.92%, -38.26%), P < 0.01], with two joinpoints in 2011 and 2014, respectively, and the tendency towards a decline showed statistical significance during the period from 2011 through 2014 [APC = -97.27%, 95% CI: (-98.65%, -88.06%), P < 0.01]. The areas of snail habitats in inner embankments appeared an average annual reduction of 4.45% in Wuhan City from 2005 to 2023 [AAPC = -4.45%, 95% CI: (-5.18%, -3.82%), P < 0.01], with three joinpoints in 2011, 2015 and 2018, respectively, and statistical significance was seen in the tendency towards a decline during the period from 2005 through 2011 [APC = -16.38%, 95% CI: (-20.15%, -14.25%), P < 0.01]. In addition, the actual areas of snail habitats appeared an average annual reduction of 2.65% in Wuhan City from 2005 to 2023 [AAPC = -2.65%, 95% CI: (-2.89%, -2.40%), P < 0.01], with a joinpoint in 2013, and the tendency towards a decline showed statistical significance during the period from 2013 through 2023 [APC = -4.06%, 95% CI: (-4.66%, -3.58%), P < 0.01]. Conclusions The integrated schistosomiasis control programme achieved significant effectiveness in Wuhan City from 2005 to 2023, with a tendency towards a decline in morbidity due to schistosomiasis in humans and livestock and snail status. The integrated schistosomiasis control strategy with emphasis on management of the source of S. japonicum infections should continue to be implemented to consolidate the schistosomiasis control achievements and achieve the goal of schistosomiasis elimination in the city.

Objective To investigate the clinical efficacy of esmolol combined with atorvastatin on se-vere sepsis complicated with cardiac insufficiency.Methods This study was a prospective,double-blind,ran-domized controlled clinical trial.A total of 153 patients with severe sepsis complicated with cardiac insufficien-cy admitted to this hospital from January 2021 to December 2022 were selected and divided into groups A,B,and C by random number table method,with 51 cases in each.Patients in group A were given routine symp-tomatic supportive treatment after admission.On this basis,patients in group B and group C were given esmo-lol,esmolol+atorvastatin,respectively.The hemodynamic indexes,serological indexes and clinical prognosis of the three groups before and after intervention were compared.Results There was no significant difference in baseline data,and hemodynamic and serological indexes of three groups before intervention(P＞0.05).Compared with before intervention,after five days of intervention,heart rate,systemic vascular resistance in-dex(SVRI),blood levels of creatine kinase-MB(CK-MB),cardiac troponin Ⅰ(cTn Ⅰ),tumor necrosis factor-α(TNF-α),interleukin-6(IL-6)and high sensitive C-reactive protein(hs-CRP)in three groups were de-creased,while the values of cardiac index(CI)were increased,and the differences were statistically significant(P＜0.05).After five days of intervention,the heart rate,SVRI,blood levels of CK-MB,cTn Ⅰ,TNF-α,IL-6,and hs-CRP in group C were lower than those in group A and group B,and the levels in group B were lower than those in group A;the value of CI in group C was higher than that in group A and group B,and group B was higher than that in group A,the differences were statistically significant(P＜0.05).After intervention,the length of stay in intensive care unit(ICU)in group C was the shortest,and that in group B was shorter than that in group A,the difference was statistically significant(P＜0.05).There was no significant difference in 28 d mortality among the three groups(P＞0.05).Conclusion Esmolol combined with atorvastatin can signif-icantly inhibit the inflammatory response in patients with severe sepsis complicated with cardiac insufficiency,relieve myocardial injury and promote rehabilitation,and the therapeutic effect is better than esmolol alone.

Objective To mine the adverse drug events(ADE)signal of avatrombopag,an effective drug for thrombocytopenia treatment,based on real world data in order to provide reference for its clinical safety application.Methods The OpenVigil2.1 pharmacovigilance platform was used to obtain the ADE report data of avatrombopag from May 2018 to March 2023 in the database of FDA adverse event reporting system(FAERS).The ADE signals were classified and described by the system organ class(SOC)and preferred term(PT)of the ADE terminology set in the Medical Dictionary for Regulatory Activities(MedDRA),and reporting odds ratio(ROR)and UK Medicines and Healthcare Products Regulatory Agency(MHRA)comprehensive standard were used to detect the positive ADE signals.Results A total of 1 879 ADE reports related to avatrombopag were obtained,24 SOCs were involved,and 28 positive ADE signals were detected at PT level.Among these signals,the strongest ones were renal vein thrombosis,portal vein thrombosis and graft versus host disease,while the reports accounting for the largest numbers were headache,fatigue and asthenia.There were 8 ADE signals discovered newly,that is,seasonal allergy,back disorder,musculoskeletal discomfort,flatulence,hypersomnia,rash macular,emotional disorder,and rhinorrhoea.Conclusion For clinical use of avatrombopag,clinicians should not only concern the risk of thrombosis,but also pay close attention to ADE signals such as seasonal allergy,back disorder,musculoskeletal discomfort,flatulence,hypersomnia,rash macular,emotional disorder,and rhinorrhoea that are not documented in the instructions.

Objective To explore the effect of Endoanal advancement flap(ERAF)and transanal opening of interphincteric space(TROPIS)in the treatment of complex anal fistula and their impact on anorectal pressure,so as to provide a reference for clinical selection of surgical methods.Methods Eighty-four patients with complex anal fistula admitted from October 2018 to October 2022 were divided into group E received ERAF treatment(n=48)and group T received TROPIS treatment(n=36).The clinical efficacy,operation,wound surface and anorectal pressure of the two groups were compared.Results The effective rate of treatment in Group T was 97.22％,which was higher than that in Group E(87.50％),with no statistically significant difference(P＞0.05).The surgical time[(31.53 ±7.29)minutes],intraoperative bleeding volume[(29.56±7.37)ml],and wound area[(10.03± 0.96)cm2,(8.76±0.87)cm2,(6.20±0.77)cm2]on the day of surgery,7 and 14 days after surgery in Group T were all smaller than those in Group E[(35.36±8.54)min,(36.86±8.04)ml,(12.09± 1.23)cm2,(10.52±1.09)cm2 and(7.36±0.85)cm2](P＜0.05).After surgery,the VAS score and Wexner incontinence score of Group T were(1.38±0.27)and(0.21±0.08),respectively.Group E was(1.56±0.29)and(0.33±0.09),respectively.In group T,the anorectal systolic pressure at 20 mm and 30 mm and the anorectal resting pressure at 20 mm and 30 mm were(138.18±29.58)mmHg,(136.22±35.41)mmHg,(35.47±6.58)mmHg,and(32.97±8.01)mmHg,respectively.In Group E,the data was(152.78±31.53)mmHg,(156.29±32.74)mmHg,(38.29±7.62)mmHg and(36.41±7.63)mmHg,respectively.Both groups showed a decrease in score and anorectal pressure,and group T was lower than group E(P＜0.05).The incidence of adverse reactions in Group E was 20.83％,which was higher than that in Group T(11.11％),but the difference was not statistically significant(P＞0.05).Conclusion TROPIS has a better effect in the treatment of complex anal fistula,which can shorten the operation time,reduce intraoperative bleeding,reduce postoperative pain,and protect anal function.

【Objective】 To explore the diagnostic value of platelet long non-coding RNA (lncRNA) as a biomarker for early screening of lung adenocarcinoma (LUAD). 【Methods】 The GSE183635 and GSE89843 datasets, which contained the platelet transcriptome of LUAD and healthy controls, were used for differential analysis, and the intersection of the differentially expressed lncRNA(DElncRNA) of the two datasets was taken. The expression levels of DElncRNA in LUAD tissues and normal control tissues were analyzed using GEPIA2. The expression levels of LINC01088 in platelets of 51 healthy controls and 54 LUAD patients were detected by quantitative Real-time PCR (qRT-PCR), and the diagnostic ability of each index was evaluated by ROC curve. 【Results】 8 DElncRNAs and 1 265 DElncRNAs were obtained from GSE183635 and GSE89843 datasets, respectively. The key DElncRNA LINC01088 was selected after intersection. GEPIA2 analysis showed that the expression level of LINC01088 in LUAD tissues was lower than that in normal lung tissues (P<0.05). Platelet LINC01088 was significantly downregulated in patients with LUAD and early-stage LUAD than in healthy controls(P<0.001). The area under the curve (AUC) of platelet LINC01088 in the diagnosis of LUAD was 0.755, the sensitivity was 81.1%, and the specificity was 67.9%. The AUC for early LUAD diagnosis was 0.727, the sensitivity was 80.0%, and the specificity was 67.9%. The AUC of the combined diagnostic model composed of platelet LINC01088 and carcinoembryonic antigen (CEA) for LUAD diagnosis was 0.807, the sensitivity was 89.2%, and the specificity was 71.4%. The AUC for early LUAD was 0.770, the sensitivity was 86.7%, and the specificity was 71.4%. The combined diagnostic model of platelet LINC01088 and CEA was superior to CEA in the diagnosis of LUAD and early LUAD (Z=-2.288, -2.34, both P<0.05). 【Conclusion】 LINC01088 is down-regulated in platelets of LUAD patients. Platelet LINC01088 may be a biomarker for early screening and diagnosis of LUAD.

OBJECTIVE To study the toxicokinetics and tissue distribution characteristics of alpha-amanitin in rats.METHODS The tail venous blood was collected from SD rats before and 5,10,20,30 and 45 min,1,1.5,2.5,4 and 8 h after intraperitoneal injection of alpha-amanitin(1.5 mg·kg-1),and the concentration of alpha-amanitin in blood was determined by liquid chromatography-mass spectrometry(LC-MS/MS).DAS 2.0 software was used to analyze and plot the drug-time curve with toxicokinetic parame-ters.Based on the toxicokinetics results,18 SD rats were randomly divided into three groups.The rats were sacrificed,and left ventricular arterial(LVA)blood and 9 types of tissue samples involving the heart,liver,spleen,lung,kidney,whole brain,small intestine,stomach wall and testis were collected 15 min,40 min and 2.5 h after dosing,and the concentrations of alpha-amanitin were measured by LC-MS/MS to obtain the tissue distribution results of alpha-amanitin in SD rats.RESULTS Toxicokinetics studies revealed that the peak blood concentration(Cmax)was(633±121)μg·L-1,the elimination half-life(T1/2)was(0.72±0.37)h,and the peak time(Tmax)was(0.52±0.16)h.The total clearance rate(CLz)was(1.62±0.26)L·h·kg-1,the area under the curve(AUC0-t)was(946±183)μg·h·L-1,and the mean reten-tion time(MRT0-t)was(1.18±0.17)h.The apparent volume of distribution(Vz)was(1.65±0.86)L·kg-1.The results of tissue distribution study showed that alpha-amanitin was widely distributed in SD rats with the highest concentration in the kidney,followed by the lung,small intestines,stomach wall,LVA blood and liver,but was low in the heart,spleen,testicles and other tissues,and very low in the brain.Alpha-amanitin was absorbed and eliminated quickly,peaked at 40 min in each tissue,and the concen-tration was minimized after 2.5 h.CONCLUSION The absorption and elimination of alpha-amanitin by intraperitoneal injection are rapid in SD rats,and the blood concentration reaches the peak about 31 min after administration,but can not be detected 4 h later.Alpha-amanitin is mainly distributed in the kidney,followed by the tissues and metabolic organs with rich blood flow,such as the lung,small intestines,stomach wall,LVA blood and liver.The content of alpha-amanitin is low in the heart,spleen,testicles and other tissues,and very low in the brain.It is speculated that it may have toxic targeting effect on the kidney and low blood-brain barrier permeability.

Objective:To compare the clinical efficacy between a single palmar lateral transverse approach and the modified Henry approach in the locking plate fixation for distal radius fractures.Methods:A retrospective study was conducted to analyze the data of 82 patients with distal radius fracture who had undergone locking plate fixation through either a single palmar lateral approach or the modified Henry approach between January 2016 and December 2022 at Department of Traumatic Orthopaedics, Taihe Hospital, Affiliated to Hubei University of Medicine. There were 25 males and 57 females, with an age of (53.8±12.7) years. Based on the difference in surgical approach, the patients were divided into a single transverse approach group ( n=42) and a modified Henry approach group ( n=40). The 2 groups were compared in terms of injury cause, injury location, time from injury to surgery, AO fracture classification, tourniquet time during surgery, incision length, fracture reduction, Patient and Observer Scar Assessment Scale (PSAS & OSAS) and Disability of the Arm, Shoulder, and Hand (DASH) score at the last follow-up, and complications after surgery. Results:There were no statistically significant differences in the baseline characteristics between the 2 groups, indicating comparability ( P>0.05). All patients were followed up for (8.2±3.5) months. Follow-ups revealed one case of injury to the palmar cutaneous branch of the median nerve but no other complications like infection, non-union, internal fixation failure, or tendon injury in the single transverse approach group. The single transverse approach group was significantly superior over the modified Henry approach group in incision length [(2.4±0.9) cm versus (5.3±1.6) cm], OSAS (8.1±4.2 versus 10.3±5.7), and PSAS (10.1±5.8 versus 14.7±6.4) ( P<0.05). There were no significant differences between the 2 groups in tourniquet time, fracture reduction quality, and DASH score at the last follow-up ( P>0.05). Conclusion:In locking plate fixation for distal radius fractures, in comparison with the modified Henry approach, a single palmar lateral approach is more minimally invasive so that more aesthetically pleasing outcomes can be achieved to facilitate patients' rapid return to work and society.

Objective:To investigate the current situation of the use of transjugular intrahepatic portosystemic shunt (TIPS) for portal hypertension, which should aid the development of TIPS in China.Methods:The China Portal Hypertension Alliance (CHESS) initiated this study that comprehensively investigated the basic situation of TIPS for portal hypertension in China through network research. The survey included the following: the number of surgical cases, main indications, the development of Early-TIPS, TIPS for portal vein cavernous transformation, collateral circulation embolization, intraoperative portal pressure gradient measurement, commonly used stent types, conventional anticoagulation and time, postoperative follow-up, obstacles, and the application of domestic instruments.Results:According to the survey, a total of 13 527 TIPS operations were carried out in 545 hospitals participating in the survey in 2021, and 94.1% of the hospital had the habit of routine follow-up after TIPS. Most hospitals believed that the main indications of TIPS were the control of acute bleeding (42.6%) and the prevention of rebleeding (40.7%). 48.1% of the teams carried out early or priority TIPS, 53.0% of the teams carried out TIPS for the cavernous transformation of the portal vein, and 81.0% chose routine embolization of collateral circulation during operation. Most of them used coils and biological glue as embolic materials, and 78.5% of the team routinely performed intraoperative portal pressure gradient measurements. In selecting TIPS stents, 57.1% of the hospitals woulel choose Viator-specific stents, 57.2% woulel choose conventional anticoagulation after TIPS, and the duration of anticoagulation was between 3-6 months (55.4%). The limitation of TIPS surgery was mainly due to cost (72.3%) and insufficient understanding of doctors in related departments (77.4%). Most teams accepted the domestic instruments used in TIPS (92.7%).Conclusions:This survey shows that TIPS treatment is an essential part of treating portal hypertension in China. The total number of TIPS cases is far from that of patients with portal hypertension. In the future, it is still necessary to popularize TIPS technology and further standardize surgical indications, routine operations, and instrument application.
