Objective To observe the clinical efficacy and safety of 0.1% mometasone furoate cream in the topical treatment of eczematous dermatoses including neurodermatitis and eczema. Methods A randomized double-blind parallel controlled clinical trial was conducted. The home made mometasone furoate cream or imported Eloson cream was topically used in patients with such dermatoses once daily for 4 weeks, respectively. Symptom/sign scores were evaluated at the beginning of the treatment and at the 1st, 2nd, 3rd, 4th week after the initiation of the treatment. Results Two hundred and eighty-four patients were enrolled in the trial, including 143 patients with eczema and 141 patients with neurodermatitis. There are 142 patients each in test group and control group separately. All symptom/sign scores and total scores were significantly decreased 1, 2, 3, and 4 week after the treatment. No statistically significant difference was observed between the two groups. The cure rate and improvement rate in eczema patients were 78.87% and 97.18% in the test group; 84.51% and 92.96% in the control group; respectively. While the cure rate and improvement rate in neurodermatitis patients were 75.71% and 100% in the test group; 80.28% and 94.37% in the control group; respectively. The cure rate and improvement rate of total patients were 77.30% and 98.58% in the test group; 82.39% and 93.64% in the control group; respectively. No statistically significant difference in efficacy was observed between the two groups. There was no severe side effect in the two groups. One patient had mild contact dermatitis in the test group. Conclusions These results suggest that 0.1% mometasone furoate cream is an effective and safe drug in the treatment of neurodermatitis and eczema.

Objective To evaluate the effect of losartan on mechanical ventilation-induced lung injury in diabetic mice.Methods Forty-eight female SPF C57/BL6 nice,aged 10-12 months,weighing 20-25 g,were randomly assigned into 3 groups (n =16 each):control group (group C).,diabetes + mechanical ventilation (group DM) and losartan group (group L).Diabetes mellitus was induced by intraperitoneal streptozotocin 150 mg/kg and confirmed by blood glucose level ＞ 16 mmol/L in groups DM and L.Diabetic mice were mechanically ventilated (FiO250％,VT 15 ml/kg,RR 70 bpm,PEEP 2 cm H2O) for4 h.Losartan 30 mg/kg was injected intraperitoneally 30 min before ventilation in group L.Eight mice from each group were chosen at 4 of ventilation and arterial blood samples were obtained for detection of PaO2.The animals were then sacrificed and the lungs were removed for determination of W/D lung weight ratio,myeloperoxidase (MPO) activity,pulmonary microvascular permeability,angiotensin Ⅱ (Ang Ⅱ) receptor AT1 mRNA expression (by RT-PCR),Ang Ⅱ content and nuclear factor kappa B (NF-κB) p65 expression (by Western blot).Results Compared with group C,PaO2 was significantly decreased,while W/D lung weight ratio,MPO activity,pulmonary microvascular permeability and Ang Ⅱ content were significantly increased,and the expression of AT1 mRNA and NF-κB p65 was up-regulated in groups DM and L (P ＜ 0.05).PaO2 was significantly higher,and W/D lung weight ratio,MPO activity,pulmonary microvascular permeability,Ang Ⅱ content and the expression of AT1 mRNA and NF-κB p65 were significantly lower in group L than in group DM (P ＜ 0.05).Conclusion Losartan can reduce mechanical ventilation-induced lung injury in diabetic mice through inhibiting AT1 receptor and Ang Ⅱ levels and improving pulmonary microvascular permeability and inhibiting NF-κB activation.

Objective To provide theoretical and experimental proof for selecting and implying Tourette's syndrome(TS) animal models, validities of four TS models induced by chemical factors were compared. Methods Four TS models,namely AMP model,APO model,DO1 model and IDPN model were built up by using different chemical modeling agents. Through detecting spontaneous movement, climbing time and monoamine transmitters levels in striatum, four TS animal models were compared and evaluated from three levels of validities-face, prediction,construct. Results Compared with control group, spontaneous movement times raised ( t = 4. 746, P =0. 000) and level of DOPAC ( (0.99 ± 0. 177 ) ng/mg) in striatum increased (P = 0.029 ), and level of NE in striatum decreased in AMP model group( (0.11 ± 0.033 )ng/mg, P = 0.012). Compared with control group, climbing time prolonged (P = 0. 004) and levels of DA ( ( 10. 19 ± 1.23 ) ng/mg), 5-HT ( ( 0. 54 ± 0.08 ) ng/mg) in striatum raised(P=0. 019, P=0. 002),at the same time ,levels of DOPAC( (0.63 ±0.11 )ng/mg),HVA ((0.45 ±0.04 ) ng/mg) in striatum reduced (P ＜ 0.01 ) in APO model group; Compared with control group, levels of DA ( ( 13.66 ± 1.55 ) ng/mg), DOPAC( (0.80 ±0. 11 ) ng/mg), HVA( ( 1.04 ± 0.14) ng/mg) grew downwards in striatum of DOI model mice(P=0.029,P=0.001, P= 0.004). Compared with control group, level of 5-HT in striatum increased in IDPN300 group ( (0.77 ± 0.09) ng/mg, P = 0.031 ). ConclusionFace validity of AMP model is temporal and that of IDPN model is steady and persistent. AMP model,APO model and DOI model possess predictive validity. AMP model,APO model,DOI model and IDPN model have potentiality of becoming construct validity model.

Early diagnosis of malignant lymphoma is often difficult since the clinical manifestation of the lymphoma occurred in the maxillofacial region is very similar to that of the squamous cell carcinoma.When the pathological diagnosis is not clear,the surgeon is easy to misdiagnose and lead to mistreatment.A patient visited the Affiliated Haikou Hospital of Xiangya School of Medicine,Central South Universily for gingival mass with an ipsilateral submaxillary enlargement.The clinical manifestation and preoperative MRI are very prone to squamous cell carcinoma with metastasis,so we did not take a preoperative pathological examination.The gingival mass was surgical removed firstly,but frozen pathological result showed that it was malignant small round cell tumor.Since the patient was diagnosed as high degree malignant of small round cell tumor and the submandibular region have been significantly metastasized,so we carried out the combined radical dissection of gingival,mandible and neck surgery.The postoperative pathological report was malignant lymphoma,suggesting that the patient was a case of misdiagnosis and mistreatment.This article draws lessons from misdiagnosis and provided experience for seeking improvement measures.

OBJECTIVE: To explore the clinical phenotype and genetic basis for a Chinese pedigree affected with Oral-facial-digital syndrome type I (OFD1). METHODS: A pedigree with OFD1 who presented at Hebei General Hospital on March 17, 2021 was selected as the subject. Clinical data of the child was collected. Trio-whole exome sequencing (trio-WES) was carried out for the proband and members of her pedigree, and candidate variant was verified by Sanger sequencing. RESULTS: The proband has featured hypotelorism, broad nasal root, flat nasal tip, lobulated tongue, tongue neoplasia, camptodactyly of left fifth finger, syndactyly of right fourth and fifth fingers, and delayed intellectual and language development. Trio-WES revealed that the proband and her daughter, sister and mother have harbored a heterozygous c.224A>G (p.Asn75Ser) variant of the OFD1 gene. The same variant was not found among healthy members from her pedigree. CONCLUSION The c.224A>G (p.Asn75Ser) variant probably underlay the OFD1 in this pedigree. Above discovery has enriched the spectrum of OFD1 gene variants.

Objective:To explore the effect of Jian-Pi-Zhi-Dong decoction on autonomous activity and dopamine (dopamine, DA) synaptic vesicle protein expression in the striatum of Tourette syndrome (TS) model rats.Methods:The 4-week-old male SD rats were used to establish the TS model by intraperitoneal injection of N-aminodipropionate. Thirty successfully modeled rats were randomly divided into model group, Chinese medicine group, and tiberide group according to random number table method, with 10 rats in each group. And another 10 rats with matched body mass were selected as the control group. Rats in Chinese medicine group were given Jian-Pi-Zhi-Dong decoction solution (1.6 g/100 g) and the rats in tiapride group were given sulfate tiapride suspension (2.1 mg/100 g), while rats in control group and model group were given an equal volume of 0.9% sodium chloride solution, once a day for 4 weeks.The number of autonomous activities in rats was determined by autonomous activity programmer. ELISA was used to detect the level of DA in the striatum of rats and the expression of dopamine transporter (DAT).Vesicular monoamine transporter-2 (VMAT2) and α-synuclein (α-syn) were measured by Western blot.SPSS 25.0 software was used for data analysis. Multiple group comparisons were performed using one-way ANOVA, non-parametric test and repeated measures ANOVA.Results:Comparing the number of autonomous activities among the 4 groups, the interaction effect between time and group was significant ( F=184.354, P<0.001). At the 1-4 weeks of gavaging, the numbers of autonomic activities in the model group were more than those in the control group (all P<0.05).While the numbers of autonomic activities in Chinese medicine group and tiapride group were less than those in the model group (all P<0.05). Moreover, the numbers of autonomic activities in Chinese medicine group and tiapride group from 1 to 4 weeks were less than those after model making (all P<0.05). The Western blot results showed significant differences in the relative expression of α-syn ( H=29.098), DAT ( F=54.632) and VMAT2 ( H=18.982) among the 4 groups (all P<0.001). The expression levels of α-syn protein in Chinese medicine group and tiapride group were both lower than that in the model group (0.39(0.36, 0.51), 0.39(0.36, 0.50), 0.62(0.50, 0.70)) (both P<0.05). The expression level of DAT protein in Chinese medicine group was higher than that in the model group and lower than that in tiapride group ((0.37±0.06), (0.26±0.07), (0.49±0.09)) (both P<0.05). And the expression level of VMAT2 protein in Chinese medicine group had no significant difference compared with that in the model group ( P>0.05).The ELISA results showed significant differences in DA content of striatum among the 4 groups ( F=75.370, P<0.001). The level of DA in the model group was higher than that in the control group ((7.65±0.72) ng/L, (3.71±0.59) ng/L, P<0.05). The levels of DA in Chinese medicine group ((3.92±0.81) ng/L) and tiapride group ((4.40±0.53) ng/L) were lower than that in the model group (both P<0.05), and the difference between Chinese medicine group and tiapride group was not significant ( P>0.05). Conclusion:Jian-Pi-Zhi-Dong decoction can relieve the tic symptoms of the model rats with TS, and its mechanism may be related to inhibiting the excessive release of α-syn, improving the expression of DAT and VMAT2, improving the DA synaptic vesicle circulation, and reducing the DA content in the synaptic space of the brain.

This paper reported the genetic analysis of a pedigree in which three affected fetuses with short limbs were revealed by first-trimester ultrasonography in three consecutive pregnancies. Tissues of the second aborted fetus were collected and analyzed by chromosome karyotype analysis and whole exome sequencing. The results indicated compound heterozygous mutations of EX64-EX83 Del and c.8190G>T in the DYNC2H1 gene. Real-time fluorescence quantitative polymerase chain reaction and Sanger sequencing further confirmed that the two variants were inherited from the father and the mother with normal phenotypes, respectively. EX64-EX83 Del was a likely pathogenic variant and c.8190G>T was a variant of uncertain significance. Based on the above results and the medical history, it was highly suspected that the fetus had autosomal recessive short rib polydactyly syndrome type Ⅲ caused by compound heterozygous variants. Real-time fluorescent quantitative polymerase chain reaction and Sanger sequencing results of the third aborted fetus were consistent with the second fetus. Given the same phenotypes of fetuses in the second and third pregnancy, it was strongly suggested that the heterozygous variations of EX64-EX83 Del and c.8190G>T in the DYNC2H1 gene were the pathogenic variants in this pedigree.

Objective To evaluate the use of endoscopic papillary balloon dilation in treatment of choledocholithiasis associated with peripapillary duodenal diverticulum.Methods From January 2017 to July 2018,a retrospective study was conducted on 124 patients with choledocholithiasis associated with peripapillary duodenal diverticula at the Department of Hepatobiliary Surgery,Second Hospital of Hebei Medical University.These patients were divided into the small endoscopic sphincterotomy combined with balloon dilation group (sEST+EPBD,n =60) and the simple papillary balloon dilation group (EPBD n =64).The operation time,one-time success rate of stone removal,complication and hospitalization stay were compared between the two groups of patients.Results The hospitalization expenses of the EPBD group was significantly less than the sEST+EPBD group (P＜0.05).The operation time of the EPBD group was significantly shorten than the sEST+EPBD group (P＜0.05).There were no significant differences in the one-time success rate of stone removal,complication rates and hospitalization stay between the two groups (P＞0.05).Conclusions Compared with sEST+EPBD,treatment of choledocholithiasis in patients with peripapillary duodenal diverticula using simple balloon dilation shortened the operation time,did not increase the complication rates and hospitalization stay.The procedure was safe and effective,and resulted in almost the same one-time success rate of stone removal.

Objective:To explore the effect of mobile health (mHealth) management system on dietary behavior of patients with coronary heart disease (CHD) .Methods:Using the convenient sampling method, CHD patients who were hospitalized in Department of Cardiology of Beijing Anzhen Hospital and Beijing Chaoyang Hospital of Capital Medical University were selected as the research objects from June 2019 to January 2020. The research objects were randomly divided into the intervention group and the control group using SAS software. Finally, 68 cases in the intervention group and 66 cases in the control group completed the study. The intervention group received mhealth management, while the control group received routine management, and they were followed up to 1 month after discharge. The proportion of patients with the low-salt and low-oil diet, the intake of salt, oil, staple food, vegetables, fruits, fish, shrimp, poultry and eggs, BMI and blood pressure were compared between the two groups.Results:At 1 month follow-up, the intervention group was better than the control group in terms of low salt and low oil diet, salt intake, oil intake and vegetable intake compliance, and the differences were statistically significant ( P<0.05) . At 1 month follow-up, there were no statistically significant differences in BMI and blood pressure between two groups ( P>0.05) . Conclusions:The mobile health system can effectively increase the proportion of patients with a low-salt and low-oil diet, and improve the intake compliance of salt, edible oil and vegetables in patients with CHD. In future studies, the intervention time should be extended to further explore the long-term intervention effect of mobile health and give full play to the role of mobile health in continuous behavior management of patients with CHD after discharge.
