OBJECTIVE To discuss the impact of Wenyang lishui formula on ventricular remodeling in rats with pulmonary hypertension-induced right heart failure （RHF） based on the Hippo/Yes-associated protein （YAP） signaling pathway. METHODS Ten rats were randomly selected as the control group. The remaining 63 rats were given a single intraperitoneal injection of monocrotaline to establish the pulmonary hypertension-induced RHF model. The 50 rats that successfully underwent the model establishment were randomly divided into the RHF group， low-dose group of Wenyang lishui formula （4.25 g/kg）， high-dose group of the Wenyang lishui formula （17.00 g/kg）， furosemide group （20 mg/kg）， and high-dose group of Wenyang lishui formula+ Hippo/YAP signaling pathway activator group （17.00 g/kg of Δ Wenyang lishui formula+16 mg/kg of PY-60）， with 10 rats in each group. The rats in each group were given the corresponding drug solution or normal saline by gavage or/andtail vein injection， once a day， for 4 consecutive weeks. During the experiment， the general conditions of the rats in each group were observed； after the last administration， the right ventricular diameter， right atrial diameter， end-diastolic volume， pulmonary artery blood flow acceleration time （PAAT） and its ratio to ejection time （ET） （PAAT/ET）， pulmonary artery pressure and its ratio to pulmonary arterial flow velocity （pulmonary artery pressure/velocity） were measured. The plasma levels of brain natriuretic peptide and angiotensin Ⅱ （Ang Ⅱ） were detected. The pathological changes of the right ventricular tissue were observed， and the collagen volume fraction， the phosphorylation levels of the large tumor suppressor 1/2 （LATS1/2） and YAP， and the protein expression of the transcriptional coactivator of PDZ-binding motif （TAZ） were also detected. RESULTS Compared with the RHF group， the rats in Wenyang lishui formula low-dose and high-dose groups showed improved hair color， movement， diet， and mental state. The atrophy of right ventricular myocardial cells， the increase of inflammatory cells， collagen deposition， and hypertrophy of myocardial fibers were significantly alleviated. The right ventricular internal diameter， right atrial internal diameter， end-diastolic volume， pulmonary artery pressure， pulmonary artery pressure/velocity， the plasma levels of brain natriuretic peptide and AngⅡ ， collagen volume fraction， the phosphorylation level of YAP and protein expression of TAZ were significantly decreased， while the PAAT， PAAT/ET and the phosphorylation level of LATS1/2 were significantly increased （P＜0.05）. PY-60 could significantly reverse the improvement effects of high-dose Wenyang lishui formula on the above quantitative indicators （P＜ 0.05）. CONCLUSIONS Wenyang lishui formula can restore the right heart function of pulmonary hypertension-induced RHF rats， reduce their pulmonary artery pressure， alleviate the pathological changes in their cardiac tissues， and the above effects may be related to the activation of Hippo expression and the inhibition of YAP phosphorylation.

Objective To explore the dynamic changes in cerebral hemodynamics in patients with unilateral middle cerebral artery(MCA)occlusion after superficial temporal artery(STA)-MCA bypass surgery.Methods One hundred and nine patients diagnosed with unilateral MCA occlusion by DSA who underwent STA-MCA bypass surgery were retrospectively included in the Department of Neurosurgery of the First Affiliated Hospital of Soochow University.Clinical data of patients were collected within 24 hours after admission,including age,sex,body mass index,stroke risk factors including hypertension,hyperlipidemia,diabetes,smoking,drinking history and atrial fibrillation,clinical manifestations(within the last 6 months;nonspecific symptoms[dizziness,memory loss,unresponsiveness,etc.],transient ischemic attack,and stroke),blood biochemical markers(low density lipoprotein cholesterol,high density lipoprotein cholesterol,triglyceride,total cholesterol,fasting blood glucose,and hypersensitive C-reactive protein),and National Institutes of Health stroke scale(NIHSS)score at admission.Color Doppler ultrasound(CDU)and transcranial color coded Doppler(TCCD)ultrasound were used to evaluate the hemodynamic parameters of STA before and at different periods after surgery(4-7 days and 1,3,6,12 months after surgery)to analyze the patency of bypass arteries and intracranial hemodynamic changes,and to check the consistency of the results of the bridge artery patency at 12 months postoperatively by CDU and DSA,consistency test was performed.According to the results of the DSA examination 12months after surgery,the patients were divided into the bypass artery patency group and the non-patency group(stenosis or occlusion).The hemodynamic parameters at the trunk of STA,namely the extracranial segment,transcranial,and intracranial part of the bypass arteries,were compared between the two groups.It included inner diameter(D),peak systolic velocity(PSV),end-diastolic velocity(EDV),resistance index(RI),pulsation index(PI),time-averaged mean velocity(TAMV),time-averaged peak velocity(TAPV),and calculated flow of the STA trunk including TAMV flow and TAPV flow.Head CT,CT angiography(CTA)above the aortic arch,and CT perfusion(CTP)of the whole brain were performed 1 to 3 days before surgery and 12 and 18 months after surgery to observe the changes in cerebral perfusion.Head CT was performed 1 to 2 days after the operation to observe whether there were new hemorrhagic and ischemic lesions in the operative area.the CTP parameters of the two groups were compared including 12 and 18 months after the operation with 1 to 3 days before the surgery,and the differences in CTP parameters between the two groups were compared.The modified Rankin scale(mRS)was used to evaluate the neurological function prognosis of the patients at 12 and 18 months after surgery.The mRS score 2 was divided into a good prognosis and mRS score≥3 was a poor prognosis.NIHSS score of the patients was recorded 7 days,12,and 18 months after surgery.Results(1)Consistency analysis of CDU and DSA:the consistency of the assessment of bypass artery patency was excellent at 12 months after surgery,and the Kappa value was 0.94(95％CI 0.81-1.00,P＜0.01).According to DSA,101 cases(92.7％)were in bypass artery patency group,while 8 cases(7.3％)in the non-patency group(no case of occluded bridge vessel was found),and the sites of stenosis in the bypass arteries were all located in the transcranial segment.(2)Hemodynamic parameters:compared with the preoperative results,the D of the extracranial segment increased on 4-7 days and 1,3,6,and 12 months after the operation(Wald x2=30.438).Hemodynamic parameters included increased blood velocity such as PSV,EDV,TAMV,and TAPV(Waldx2 was 12.117,29.310,31.075 and 17.525,respectively)and blood flow including TAMV flow and TAPV flow(Wald x2 was 54.503 and 34.986,respectively)increased,while RI and PI values were decreased(Waldx2 was 112.568 and 103.629,respectively),and the differences were statistically significant(all P＜0.05).However,there was no significant difference in hemodynamic parameters in the non-patency group at 12 months after operation(all P＞0.05).Compared with 4-7 days after surgery,PSV(252.0[206.8,315.3]cm/s vs.102.5[84.0,119.0]cm/s)and EDV(119.5[106.3,159.8]cm/s vs.43.5[36.8,52.0]cm/s)in the non-patency group were significantly higher at the cranial entrance 12 months after surgery(both P＜0.05),but there was no significant difference in RI and PI values(both P＞0.05).Compared with 4-7 days after surgery,the blood flow parameters of STA intracranial segment,including PSV(29.4[24.8,41.4]cm/s vs.111.5[63.3,120.0]cm/s),EDV(19.7[15.2,22.2]cm/s vs.58.5[28.3,70.0]cm/s)and PI(0.55[0.42,0.63]vs.0.83[0.61,0.90])values in the non-patency group at 12 months after surgery were significantly decreased(all P＜0.05).(3)CTP parameters:the relative cerebral blood flow(rCBF)of the patency group increased at 12 and 18 months after surgery compared to preoperative levels,while relative cerebral blood volume(rCBV),relative peak time(rTTP)and relative mean transit time(rMTT)decreased,with statistical significance(all P＜0.05).At 12 and 18 months after operation,rCBF increased,while rMTT decreased in the non-patency group(both P＜0.05),but there was no significant difference as for rCBV and rTTP.The rTTP of the patency group at 12 and 1 8 months was lower than that of the non-patency group(12 months after surgery:1.14[1.06,1.15]vs.1.20[1.14,1.28],P=0.024;1 8 months after surgery:1.14[1.06,1.15]vs.1.20[1.14,1.28],P=0.023),but there was no statistical significance for other parameters between the two groups(all P＞0.05).(4)NIHSS score and prognosis:clinical follow-up results 18 months after the operation showed that no new stroke occurred during the follow-up period.The NIHSS scores in the patency group and the non-patency group were remarkably lower at 7 days,12,and 18 months after surgery than at admission(patency group:2[0,4],1[0,2],0[0,2]vs.3[0,6],respectively;the non-patency group:3[1,5],3[1,6],2[1,6]vs.4[1,7],respectively),with significant differences(all P＜0.05);However,the NIHSS scores in the patency group were significantly lower than that in the non-patency group at 12 and 18 months after surgery,and the proportion of patients with good prognosis in the patency group was substantially higher than that in the non-patency group(12months:87.1％[88/101]vs.4/8,P=0.039;18 months:90.1％[91/101]vs.4/8,P=0.025).Conclusion CDU can quantitatively evaluate the hemodynamic changes of bypass arteries after the STA-MCA bypass procedure,which can be applied to the long-term dynamic follow-up after the surgery.

Objective:To confirm the efficacy and safety of cinepazide maleate injection in acute ischemic stroke patients with obvious motor function deficit.Methods:This study is a subgroup analysis of multi-center, randomized, double-blind, placebo-controlled phase Ⅳ clinical trial. A total 812 patients of acute ischemic stroke with obvious limb motor deficit [motor function of limbs score in National Institutes of Health Stroke Scale (NIHSS) ≥4] were enrolled in this subgroup analysis. Patients received either cinepazide maleate injection or placebo. The treatment period was 14 days and follow-up was 90 days. The efficacy endpoints included the proportions of patients with a modified Rankin Scale (mRS) score ≤2, mRS score ≤1 and Barthel Index <95 on day 90. Safety was evaluated by recording all adverse events, monitoring vital signs, laboratory parameters and electrocardiogram.Results:A total of 732 patients were involved in the final efficacy analysis (361 in cinepazide maleate group and 371 in control group). The baseline limb motor function score of NIHSS was 5.23±1.43 in the cinepazide maleate group whereas 5.20±1.36 in the control group. Logistic regression analysis showed that following treatment for 90 days, the proportion of patients with a mRS score ≤2 was significantly higher in the cinepazide maleate group than in the control group [56.0% (202/361) vs 44.2% (164/371), OR=0.60, 95% CI 0.44-0.82, P=0.002]. The proportion of patients with a mRS score ≤1 was higher in the cinepazide maleate group than in the control group [43.3% (139/361) vs 35.2% (118/371), OR=0.69, 95% CI 0.50-0.97, P=0.031]. The proportion of patients with a Barthel Index <95 on day 90 was significantly lower in the cinepazide maleate group than in the control group [45.2% (145/361) vs 55.2% (185/371), OR=0.64, 95% CI 0.46-0.88, P=0.007]. During the treatment and follow-up period, the incidence of the most common adverse events in the cinepazide maleate group was 50.4% (199/395). Constipation and abnormal liver function were more common, but there were no statistically significant differences between the two groups. Conclusion:Cinepazide maleate injection is superior to placebo in improving neurological function and activities of daily living, reducing disability, and promoting functional recovery and safe in patients with acute ischemic stroke with obvious limb motor deficit.

Objective:To investigate the status of family function of patients after hysterectomy, explore the effect of self-concealment on family function.Methods:From January to November 2021,the 177 patients after hysterectomy in Guangdong Provincial People ′s Hospital were investigated by General Data Questionnaire, Family APGAR Indexand Self-Concealment Scale (SCS), and the influencing factors of family function were analyzed by univariate analysis and binary logistic regression. Results:The total score of APGAR and SCS was 9.00 (6.50, 10.00) and 24.00 (17.00, 33.00) after hysterectomy. Univariate analysis showed that marital status, working conditions and tendency of self-concealment were the influencing factors of family function. In the regression analysis of binary Logistic, tendency of self-concealment( P<0.01) and marital status ( P<0.01) entered the regression equation. Conclusions:The family function of patients after hysterectomy is generally good, and self-concealment is a risk factor. It is suggested that in clinical work, attention should be paid to the tendency of self-concealment in patients after hysterectomy, and targeted intervention measures should be taken to improve their family function.

Lung cancer is one of the malignant tumors with the highest morbidity and mortality rate, and effective screening and early diagnosis methods can significantly reduce the morbidity and mortality rate of lung cancer patients. Traditional lung cancer detection methods mainly include imaging tests, sputum cell tests, bronchoscopy, and needle biopsy, but these methods have disadvantages such as being highly invasive, complicated operation processes, prone to false positives, and low detection index. Tumor markers can reflect the occurrence and development of tumors and can monitor the effect of tumor treatment. Therefore, tumor marker detection is of great significance for early cancer diagnosis. Biosensor technology is a new rapid detection technology with promising applications. In recent years, research related to biosensors has been intensified in clinical testing and biomedicine. In this paper, the traditional detection methods for lung cancer were briefly introduced, and the technologies and detection methods related to optical or electrochemical lung cancer tumor marker biosensors based on immunology, nanomaterials, and aptamers were highlighted in recent years, and the future development trend of lung cancer tumor marker biosensors was prospected.

Objective:To explore the current level of knowledge, attitude and practice of rehabilitation for postpartum diastasis recti abdominis inpuerperae, and analysis the influencing factors of behavior, in order to provide a reference frame for nursing staff to formulate effective health education programs.Methods:From November 2020 to April 2021, a self-designed questionnaire was used to investigate 522 puerperae from 4 tertiary hospitals in Guangdong province, Jiangsu province and Zhejiang province, to explore their level of knowledge, attitude and behavior of rehabilitation for postpartum diastasis recti abdominis. Mann-Whitney Utest or Kruskal-Wallis Htest was used for univariate analysis, Binary Logistic regression analysis was used to analysis the influencing factors of rehabilitative behavior.Results:The median score of knowledgedimension, attitude dimension and behavior dimension of rehabilitation for postpartum diastaisis recti abdominis in puerperae respectively were 47.0 (36.0, 55.0), 26.0 (24.0, 31.0), 15.0 (10.0, 18.0) points. The results show that the main factors influencing of rehabilitation behaviorfor postpartum diastaisis recti abdominis in puerperae were knowledge ( χ2 = 87.78, P<0.05), attitude ( χ2 = 4.77, P<0.05), number of deliveries ( χ2 = 3.94, P<0.05) and family personal monthly income ( χ2 = 4.88, P<0.05). Conclusions:At present, puerperae have a positive attitude towards rehabilitation for postpartum diastasis recti abdominis, but the level of knowledge and practice of rehabilitation for postpartum diastasis recti abdominisneed to be improved.Nursing staff should focus on puerperae with incomplete knowledge, negative attitude, multiple deliveries and low family personal monthly income.

Objective:To investigate the blood pressure change in patients with acute ischemic stroke (AIS) and hypertension treated with cinepazide maleate injection.Methods:This was a subgroup analysis of post-marketing clinical confirmation study of cinepazide maleate injection for acute ischemic stroke: a randomized, double-blinded, multicenter, placebo-parallel controlled trial, which conducted in China from August 2016 to February 2019. Eligible patients fulfilled the inclusive criteria of acute anterior circulation ischemic stroke with National Institutes of Health Stroke Scale (NIHSS) scores of 7-25. The primary endpoints were mean blood pressure of AIS patients treated with cinepazide maleate or control, which were assessed during the treatment period (14 days), and the proportion of the patients with normal blood pressure was analyzed after the treatment period. Furthermore, a subgroup analysis was performed to investigate a possible effect of the history of hypertension on outcomes.Results:This analysis included 809 patients with hypertension. There was no significant difference in patients blood pressure and the proportion of patients with normal blood pressure (60.5% vs. 59.0%, P>0.05) between cinepazide maleate group and control group. Conclusion:Administration of cinepazide maleate injection does not affect the management of clinical blood pressure in patients with AIS.

Objective:To verify the application value of team-based learning (TBL) joint case-based discussion (CBD) method applied in the course teaching of Introduction to General Practice.Methods:Students from two clinical oriented classes in the same grade were divided into the experimental group ( n=35) and the control group ( n=35).

Objective: To explore the clinical features, diagnosis and prognosis of renal transplant recipients with NCP. Method: The clinical data of 2 cases of kidney transplant recipients with NCP were retrospectively analyzed. Based onclinical manifestations, blood routine, inflammatory factors, cell immunity, chest CT andtherapeutic effects, the diagnosis and treatment of NCP in kidney transplant recipients (5th edition) were compared to that ofordinary NCP patients. Both recipients developed onset of low andmoderate fever, with no cough or fatigue at the initial stage. Blood routine indicated a normal range of leukocytes,buta significant decrease in lymphocyte counts, increased C-reactive protein (CRP) , and slightly higher procalcitonin (PCT) . The cellular immunity was extremely low, and the chest CT showed multiple patchy ground glass shadows in both lungs. Result: After 1 week of onset, both patients had significant disease progression. The pathogenesis and imaging changes were highly similar tothatreported in ordinary NCP patients.Two patients were givensymptomatic supportive treatment by antiviral agents, stop uses ofimmunosuppression agents, small amount of hormone maintenance, intravenous drip of gamma globulin andrespiratory support toavoid secondary infections. At present, the condition of both patients is obviously improved, and renal function is stable. One of them has recovered and was discharged. Conclusion The clinical manifestations of NCP in renal transplant recipients were generally consistent with that of ordinary NCP patients. Although there is no established method for the treatment of NCP, it is effective by stopping uses of immunosuppressive agents, maintaining small and medium doses of hormones, actively restoring immunity, and providing respiratory support in a timely manner.
