Pathological dry skin is a disturbing and intractable healthcare burden,characterized by epithelial hy-perplasia and severe itch.Atopic dermatitis(AD)and psoriasis models with complications of dry skin have been studied using single-cell RNA sequencing(scRNA-seq).However,scRNA-seq analysis of the dry skin mouse model(acetone/ether/water(AEW)-treated model)is still lacking.Here,we used scRNA-seq and in situ hybridization to identify a novel proliferative basal cell(PBC)state that exclusively expresses transcription factor CUT-like homeobox 1(Cux1).Further in vitro study demonstrated that Cux1 is vital for keratinocyte proliferation by regulating a series of cyclin-dependent kinases(CDKs)and cyclins.Clinically,Cux1+PBCs were increased in patients with psoriasis,suggesting that Cux1+ PBCs play an important part in epidermal hyperplasia.This study presents a systematic knowledge of the tran-scriptomic changes in a chronic dry skin mouse model,as well as a potential therapeutic target against dry skin-related dermatoses.

Objective:To study the mid- and long-term outcomes of the cryopreserved homograft conduits used in the Rastelli operation and to identify the risk factors for the homograft conduit degeneration and reintervention.Methods:52 patients were followed up from 7 to 18 years, who accepted the Rastelli operation with cryopreserved homograft conduits between April 2002 and December 2013. There were 36 male and 16 female with age ranged 3 to 14 years old(median age 4 years old)and weight ranged 10 to 36 kg(median weight 14 kg). The homografts included aortic homografts implanted in 30 cases and pulmonary homografts implanted in 22 cases.The homograft conduits were divided into three groups by conduit diameter: groupⅠ(16 mm)22 cases, groupⅡ(16-20 mm)22 cases and group Ⅲ(≥20 mm)8 cases. The pathological characteristics of homografts were studied in the period of follow-up.Results:52 patinets were followed up from 7 to 18 years( median time 12 years). Over the follow up period, all homograft conduits had structural valve degeneration.The predominant pathological characteristics was stenosis of conduits. 37 patinets had received the reoperation because of the homograft degeneration. The interval between the first and reoperation is ranged 9 to 18 years( median time 12 years). Univariate analysis demonstrated young operation age(<5 years old)( P<0.001), diameter of the homograft conduit( P<0.001), high right ventricular pressure(RV/Ao P>0.5) after Rastelli operation( P=0.002)were independent risk factors for the homograft conduit degeneration. Univariate analysis demonstrated only young operation age(<5 years old)( P=0.03)was independent risk factor for the reoperation. Conclusion:In young patients, oversize homograft conduit and enlarge incision with Gore-Tex conduit may improve durability and decay the time of reintervention.

Objective:To evaluate the effect of combined use of Guben-Tiaoping Decoction on the success rate of stepwise treatment and life quality of asthma patients. Methods:A total of 76 patients with asthma in remission stage who were using ICS were divided into treatment group (38 cases) and control group(38 cases) according to random number table. Both groups were treated with ICS reduction based on the 2017 Gina Protocol. The treatment group was treated with Guben-Tiaoping Decoction for 12 weeks. The number of patients who were able to successfully complete the stepwise treatment after the end of the trial was calculated, the relevant indexes of Asthma Control Test (ACT), TCM Syndrome score, St. George’s respiratory questionnaire (SGRQ) and lung function were collected before and after treatment. Result:After 12 weeks’ treatment, the success rate of stepwise was 89.5% (34/38) in the treatment group and 78.9% (30/38) in the control group ( χ2=14.862, P=0.001). Meanwhile, the ACT score of the treatment group were better than those in the control group (Daytime symptoms t=-3.860, P=0.001, Dyspnea t=-2.007, P=0.40, Night waking t=-2.732, P=0.009, Reliever needed for symptoms t=-2.262, P=0.031, Control situation t=-6.994, P=0.001, Total Score t=-9.562, P=0.001). The score of TCM Syndrome in the treatment group was significantly lower than that of the control group ( P=0.001); PEF in treatment group [(6.92 ± 1.71) L vs. (5.84 ± 1.22) L; t=-2.880, P=0.005] was significantly better than that of the control group. Conclusion:Guben-Tiaoping Decoction is helpful to improve the success rate of ICS stepwise treatment and the life quality of patients.

Objective: To evaluate the effects of office blood pressure(OBP)combined with ambulatory blood pressure monitoring(ABPM)on the diagnosis of hypertension. Methods: The residents aged 35-79 years without hypertension history,whose casual OBP were 120~159 mm Hg/80~99 mm Hg,were enrolled from 4 communities of Hangzhou and Zhuji from 2015 to 2018. They were performed OBP measurements on other two days in 4 weeks and ABPM in a week. There were 2 criteria of OBP as elevated OBP on the first day or in 3 different days,and 4 criteria of ABPM as elevated mean BP in 24 hours, daytime, nighttime and either of the above time. Receiver operating characteristic(ROC)curve was employed to evaluate the effects of different OBP criteria combined with ABPM criteria on the diagnosis of masked hypertension(MH)and white-coat hypertension(WCH). Results: Taking 3-day-OBP as a golden standard,the 1-day-OBP with 4 ABPM criteria had the areas under the ROC curve(AUC)of 0.79-0.81,sensitivity of 57.58%-62.77% and specificity of 100.00% in MH;had the AUC of 0.95-0.98,sensitivity of 100.00% and specificity of 88.96%-96.80% in WCH. The Kappa values were all less than 0.6,known as low consistency. Taking either time of ABPM as a golden standard,24 hours,daytime and nighttime ABPM criteria with OBP had the AUC of 0.90-0.92,sensitivity of 79.17%-83.90% and specificity of 100.00% in MH(all Kappa>0.6),when with 1-day-OBP,the Kappa values were all more than 0.8,known as high consistency;had the AUC of 0.95-1.00,sensitivity of 100.00% and specificity of 89.54%-99.37% in WCH,the Kappa values of daytime ABPM were all more than 0.6,known as high consistency. Conclusions If limited by options, 1-day-OBP could be used instead of 3-day-OBP for detection of WCH or exclusion of MH yet with less accuracy; 24 hours or daytime ABPM instead of either time of ABPM was reliable.

Objective:To analyse the clinical outcomes in patients after systemic-pulmonary shunt in order to improve the early and interim outcome and decrease the operative complications.Methods:Between June 2009 and December 2017, 92 patients with age from 3 months to 40 years, and weight from 3.5 to 60.0 kg, underwent a systemic-pulmonary shunt. Indications for surgical palliation were tetralogy of Fallot(TOF) in 31 patients, pulmonary atresia(PA)with ventricular septal defect with in 29 patients, PA with intact ventricular in 3 patients, functional single ventricle(SV)with pulmonary stenosis(PS) in 8 patients, double outlet right ventricle(DORV) with PS in 8 patients, transposition of the great arteries(TGA) with PS in 5 patients, TGA with PA in 3 patients, corrective transposition of the great arteries(ccTGA) with PA in 2 patients, the others in 3 patients. 30 patients were with PDA. The surgical procedure included modified Blalock-Taussig(B-T) shunt in 55 patients, central aortopulmonary shunt(Waterston)in 31 patients, and Melbourne shunt in 6 patients.Results:There were 7 early operative deaths, the early mortality was 7.6%. There were 9 patients with acute shunt blockage within the first 24 h, including TOF(2 patients), PA/VSD(4 patients), DORV/PS(1 patient), cCTGA/PA(1 patinet) and TA/PS(1 patinet). There was only 1 patient with acute shunt blockage after 2015. Overall , 48(48/85, 56.5%) patients were bridged to the comlpete repair or the second stage of Fontan operation. 7 patients were received the second shunt operations. 30 patients were still waiting for the next therapy.Conclusion:Systemic-pulmonary shunt is not a so-simple palliative procedure, the good early and interim outcome is associated with the choice of shunt method and perioperative treatment of complications.

Objective:To investigate the related risk factors for the prognosis of hospital-acquired carbapenem-resistant Klebsiella pneumoniae (CRKP) bloodstream infections in elderly patients with critical illness.Methods:Clinical data of elderly patients with nosocomial CRKP bloodstream infection in intensive care unit (ICU) from Jan. 2010 to Dec. 2016 were retrospectively analyzed. Patients were divided into the death and survival groups according to the prognosis. Clinical characteristics were compared between the two groups. Influencing factors for the prognosis of nosocomial CRKP bloodstream infections in elderly ICU patients were screened by multivariate Logistic regression analysis.Results:A total of 119 elderly ICU patients with nosocomial CRKP bloodstream infection were enrolled. The overall ICU mortality rate was 62.2% (74/119 patients), among which the ICU mortality was lower in patients treated with tigecycline than without tigecycline treatment (50.0% or 25/50 vs. 71.0% or 49/69, χ2=4.770, P=0.029). And the ICU mortality was lower in patients with combination therapy than with mono-therapy (54.9% or 39/71 vs. 72.9% or 35/48, χ2=3.940, P=0.047). Multivariate Logistic regression analysis revealed that the administration of vasoactive drugs ( OR=25.545, 95% CI: 9.743-52.242, P=0.001), and the resistance to tigecycline ( OR=8.990, 95% CI: 0.957-24.488, P=0.049) were independent risk factors for ICU mortality. While the early initiated appropriate antibiotics treatment, which was defined as using at least one susceptible antibiotic within 48 hours ( OR=0.081, 95% CI: 0.014-0.463, P=0.005), and appropriate antibiotics and adequate duration ( OR=0.785, 95% CI: 0.631-0.977, P=0.030), were protective factors for the good outcome. Conclusions:Nosocomial CRKP bloodstream infection in elderly ICU patients leads a high ICU mortality rate. The early initiated appropriate antibiotics treatment and optimum antibiotics duration could reduce the risk for death.

To evaluate the long term cardiopulmonary function after Fontan operation. Methods 10 patients who received Fontan operation were followed for(26 ±4) years in our hospital. 7 males and 3 females,(30. 7 ± 13. 2) years old(20 -60 years). All patients were diagnosed by echocardiography, CTA, 24 h ECG, cardiac catheterization, pulmonary angiography, radionuclide pulmonary blood perfusion and cardiopulmonary exercise test. Results Echocardiography shows: LVEF(0. 49 ± 0. 04), more than moderate atrioventricular valve regurgitation in 7 cases. CTA shows: there was no anastomotic stenosis, arteriovenous fistula in 4 cases. 24 h ECG shows: sinus rhythm in 7 cases, frequent paroxysmal atrial tachycardia in 1 case, atrial flutter in one and atrial fibrillation in one. Cardiac catheterization and pulmonary angiography show: the average pulmonary artery pressure(17. 8 ±2. 0)mmHg, average pulmonary resistance(4. 17 ±0. 56) woods. Radionuclide pulmonary blood perfusion shows: pulmonary blood of upper lung was reduced significantly with unbalanced distribution. Cardiopulmonary exercise test shows: both of lung ventilation function and heart reserve function decreased moderately or severely. Protein losing enteropathy was found in 1 case. Conclusion The decrease of cardiopulmonary function is found after Fontan operation during the long-term follow up for 20 years, especially for cardiac function. More attention should be paid to the early postoperative atrioventricular valve regurgitation. Unbalanced distribution of pulmonary blood is Found in long term. The incidence of arrhythmia after extra conduit Fontan operation is lower than other methods.

Objective: To evaluate the efficacy and safety of Yupingfeng powder in conjunction treatment of western medicine on cough variant asthma (CVA). Methods: We searched CNKI, Wanfang database, VIP database and PubMed through computer from the database building to October 31st 2017. The randomized controlled trails (RCT) with the comparison in the treatment of CVA with Yupingfeng powder and western medicinal were identified and included. The quality of RCTs was assessed by Jadad scores, and meta-analyses were performed by Review Manager 5.3 software. Results: Totally 15 RCTs involving 1 318 patients were included into the study, which all belonged to the low methodological quality. The meta-analysis results showed that compared with the western medicine alone, the treatment in conjunction of Yupingfeng powder can significantly improve the clinical effective rate [OR=3.45, 95% CI (2.38-5.02), P<0.01], reduce the recurrence rate [OR=0.25, 95% CI (0.16-0.38), P<0.01]. There were no statistical significant differences with untoward effect between above two treatment groups [OR=0.70, 95% CI (0.34-1.46), P=0.35]. Conclusions The Yupingfeng powder combined with the routine therapy may improve the clinical effective rate, and reduce the recurrence rate for CVA patients. However, we need more high-quality RCTs to comfirm such results.

Objective: To investigate the clinical values of colposcopy and cervical biopsy and/or endocervical curettage (ECC) in the diagnosis of cervical lesion. Methods: Clinical data of 128 cases of cervical lesion diagnosed by Xuzhou Cancer Hospital from January 23, 2014 to October 11, 2016 were collected and retrospectively analyzed, all patients underwent colposcopy and cervical biopsy and/or ECC. Results: Among them, the age between 30 to 50 years old were 70 cases, whose transformation zone types of Ⅰ, Ⅱ and Ⅲ were 28 cases (40.0%), 23 cases (32.9%) and 19 cases (27.1%), respectively. The age older than 50 years were 45 cases, whose transformation zone types of Ⅱ and Ⅲ were 1 case (2.2%) and 44 cases (97.8%), respectively. Among the 128 cases of cervical lesions, diagnostic results of colposcopy showed that the chronic inflammation were 57 cases, cervical intraepithelial neoplasia (CIN)Ⅰwere 35 cases, CINⅡor CINⅡ~Ⅲ were 8 cases, CIN Ⅲ were 5 cases and cervical cancer were 23 cases. Alternatively, the pathological results showed that the chronic inflammation were 81 cases, CINⅠwere 17 cases, CINⅡor CINⅡ~Ⅲ were 7 cases, CIN Ⅲ were 5 cases and cervical cancer were 18 cases, respectively. Among the 81 cases of chronic inflammation diagnosed by pathology, 52 cases (64.2%) were consistent with the diagnostic results of colposcopy. Among the 17 cases of low grade squamous epithelial cell lesion (LSIL) diagnosed by pathology, 10 cases were in agree with the diagnostic results of colposcopy. Among the 12 cases of high-grade squamous epithelial cell lesion (HSIL) diagnosed by pathology, 9 cases were concordant with the diagnostic results of colposcopy. Among the 18 cases of cervical cancer diagnosed by pathology, 17 cases were consistent with the diagnostic results of colposcopy. Conclusions The type of transformation zone is positively correlated with the age, and it can help to choose biopsy and therapeutic manner. The diagnostic accuracies of HSIL and early stage of cervical cancer by multi-point biopsy of colposcopy and/or ECC are high. The cervical lesions which are difficultly found by direct visualization can be identified by colposcopy, and thus provides objective evidence to determine the therapeutic manner for patients with stage ⅡA of cervical cancer.

In the central nervous system, gap junctions exist between neurons and glial cells. Among them, connexin 43 (Cx43) is one of the most abundant connexin proteins in the central nervous system,involved in the metabolic coupling of intercellular substance exchange and electrical coupling of electrical signaling. It plays an important role in regulating cell metabolism, homeostasis, and cell differentiation. After cerebral ischemia, the uncoupling of gap junctions and abnormal hemichannel activity cause a steady-state imbalance of the internal and external environment of the cells, eventually leading to brain tissue damage.Therefore, maintaining the normal function of Cx43 is essential for protecting brain tissue from neuronal damage induced by cerebral ischemia-reperfusion.
