ABSTRACT
Objective:To initially investigate whether simultaneous radiochemotherapy with hyperthermia can prolong the survival of glioblastoma (GBM) patients.Methods:Clinical data of 61 GBM patients undergoing surgery in our hospital from September 2016 to June 2019 were retrospectively analyzed. According to different treatment methods, all patients were divided into the control group ( n=34) and observation group ( n=27). In the control group, three-dimensional radiotherapy with a dose of 60 Gy combined with temoazolamine chemotherapy was delivered. In the observation group, simultaneous radiochemotherapy with 15-20 cycles of hyperthermia at 40-41℃ was supplemented. The survival time was calculated by Kaplan-Meier method, and the survival time was compared with log-rank test between two groups. Results:The median progression-free survival in the observation group was significantly longer than that in the control group (14.33 months vs.9.94 months, P<0.05). The median overall survival in the observation group was also remarkably higher than that in the control group (18 months vs. 14 months, P<0.05). Conclusions:Simultaneous radiochemotherapy with hyperthermia is innovatively applied to treat GBM after surgical resection. Preliminary findings demonstrate that compared with chemoradiotherapy, simultaneous radiochemotherapy with hyperthermia can prolong the survival time of GBM patients.
ABSTRACT
Objective:To evaluate the clinical value of temporal pole and external capsule white matter hyperintensities (WMHs) on the diagnosie of cerebral autosomal dominant arteriopathy with subcortical infarcts and leukoencephalopathy (CADASIL) by meta-analysis.Methods:PubMed, Cochrane, Embase, VIP database, China Biomedical Literature database, CNKI, Wanfang Data Service Platform were retrieved. The relevant literature of temporal pole and external capsule WMHs for the diagnosis of CADASIL was collected. The retrieval time limit was from the establishment of the databases to April 1, 2020. Quality Assessment of Diagnostic Accuracy Studies-2 (QUADAS-2) was used to evaluate the quality of literature. Stata 15.1 software was used for statistical analysis. The fitted Summary Receiver Operating Characteristic (SROC) curve and combined diagnostic effect size were used to evaluate the diagnostic value of temporal pole and external capsule WMHs for CADASIL.Results:A total of 9 articles involving 10 studies were enrolled, including 880 patients. The combined sensitivities of temporal pole and external capsule WMHs for CADASIL were 0.67 (95% confidence interval [ CI] 0.54-0.78) and 0.84 (95% CI 0.72-0.91) respectively, the combined specificities were 0.64 (95% CI 0.47-0.78) and 0.44 (95% CI 0.36-0.53) respectively, the combined positive likelihood ratios were 1.9 (95% CI 1.4-2.6) and 1.5 (95% CI 1.2-1.8) respectively, the combined negative likelihood ratios were 0.51 (95% CI 0.42-0.63) and 0.37 (95% CI 0.20-0.69) respectively, the odds ratios of combined diagnosis were 4 (95% CI 3-5) and 4 (95% CI 2-9) respectively, and the area under the SROC curves were 0.71 (95% CI 0.66-0.74) and 0.62 (95% CI 0.58-0.66) respectively. Conclusions:The temporal pole and external capsule WMHs have limited diagnostic value for CADASIL, and other factors need to be comprehensively considered in the clinical diagnosis process.

ABSTRACT
Objective:To summarize the clinical and imaging features of five patients of cerebral autosomal dominant arteriopathy with subcortical infarcts and leukoencephalopathy (CADASIL) with cysteine-sparing NOTCH3 gene missense mutations and explore potential pathogenicity of gene mutations.Methods:The clinical data from five patients who were admitted to the People′s Hospital of Zhengzhou University from March 2017 to November 2018 were collected. The patients were found to carry cysteine-sparing NOTCH3 gene mutations through genetic testing and diagnosed pathologically. They were probands confirmed from five unrelated family and all five patients were performed full exon detection and skin biopsy.Results:Genetic testing identified five patients with cysteine-sparing NOTCH3 gene missense mutations, a total of five different mutations, including p.R75Q, p.D80G, p.V237M, p.S1418L and p.R1761H. The first three mutations were found in the epidermal growth factor-like repeats (EGFr), the latter two mutations near the transmembrane domain. Granular osmiophilic material was identified in all cases examined with skin biopsy. The age at initial symptom onset of these five cases was ranged from 22 to 58 years and three cases presented cardiovascular risk factors. The primary clinical manifestations included migraine in one case, ischemic stroke in three cases, psychiatric disturbances in four cases, cognitive dysfunction in five cases, while gait disturbance, pseudobulbar palsy, and seizures accounted for only one case each. Magnetic resonance imaging of five patients all showed white matter hyperintensities (WMLs) and lacunar infarcts, and WMLs involved the anterior temporal pole and external capsules in three cases separately. According to the criteria proposed by Mui?o et al for evaluating the pathogenicity of cysteine-sparing NOTCH3 mutations, all five mutations are potentially pathogenic.Conclusions:Most characteristics of CADASIL patients with cysteine-sparing NOTCH3 gene mutations are similar to those of CADASIL patients with cysteine NOTCH3 gene mutations. Mutations not involving the EGFr may also have potential pathogenicity, and the specific mechanism still needs further study.

ABSTRACT
To explore the efficacy and mechanism of fire needling for chronic gastritis, "fire needling" and "chronic gastritis" were selected as keywords to collect literature in PubMed, CNKI database anddatabase. The clinical and experiment literature regarding fire needling for chronic gastritis was analyzed to make a comprehensive discussion on the efficacy and action mechanism of fire needling for chronic gastritis. The results indicated the efficacy of fire needling for chronic gastritis was superior to that of medication or filiform needle. The combination of fire needling and medication, acupoint injection and filiform needle could further improve the therapeutic effect for chronic gastritis. From the perspectives of TCM and western medicine, the action mechanism of fire needling for chronic gastritis was explored, and it was believed the fire-needle therapy has the effects of removing and nourishing, which conformed to the clinical syndromes of chronic gastritis. The fire needle could affect the prognosis by regulating the central nerve system, improving local blood circulation, regulating immune inflammation and regulating gastrointestinal hormones.
ABSTRACT
OBJECTIVE To investigate the relationship between the distribution of eosinophils(Eos) of nasal secretion and serum specific IgE(sIgE) titer in patients with allergic rhinitis, and to evaluate the diagnostic value of Eos in nasal secretion for allergic rhinitis. METHODS A total of 60 allergic rhinitis patients from Department of Otolaryngology, Beijing Shunyi Hospital of Traditional Chinese Medicine during Jan.2016 to June 2017 were selected as treatment group, and another 60 cases of non-allergic rhinitis and 30 normal persons in the corresponding time period were chosen as control group. Eos in nasal secretions and serum sIgE were measured in all the subjects and the relationship between Eos distribution and serum sIgE level was analyzed. RESULTS The Eos distribution and serum level of sIgE was consistent(κ=0.264, P=0.000) and statistical significance was found. The area of ROC of the Eos in nasal secretion was 0.881, the standard deviation was 0.025 and 95％ confidence interval was 0.841 to 0.924. The Udden index of ROC reached the maximum when the Eos in nasal secretion smear was graded as level 3, the sensitivity was 88.5％ and specificity was 99.4％. CONCLUSION Eos cytological examination of nasal secretions has some auxiliary value in the diagnosis of allergic rhinitis. It is a cheap, simple and rapid method, which can be used as an effective reference index for diagnosing allergic rhinitis in primary hospital.

ABSTRACT
Objective@#To identify the special biomarkers and the differentially expressed proteins in keloid tissue and to explore the pathogenesis characteristics of familial keloid by comparing the protein expression differences among familial keloid(FK), sporadic keloid(SK), hypertrophy scar (HS), normal scar (NS).@*Methods@#The tissue specimens of FK, SK, HS and NS(6 specimens in each group), were digested, taged and analysed using quantitative proteomic isobaric tags for relative and absolute quantitation (iTRAQ) labeling technology. A difference greater than 1.2 folds and P<0.05 were selection criteria for differencial expression proteins. Then bioinformatics analysis was applied.The expressions of 2 differential proteins were validated using Western Blot analysis.@*Results@#A total of 2 450 differentially expressed proteins were identified. Compared with NS, 250 up-regulated and 281 down-regulated proteins were identified in FK; 281 up-regulated and 232 down-regulated proteins were identified in SK; 199 up-regulated and 233 down-regulated proteins were identified in HS.Compared with SK, 64 up-regulated and 164 down-regulated proteins were identified in FK; 79 up-regulated and 169 down-regulated proteins were identified in HS.Compared with HS, 124 up-regulated and 115 down-regulated proteins were identified in FK.These different proteins were concentrated in several vital signal pathways such as the extracellular matrix protein, cell adhesion and biological metabolism pathways. The variation trend of 2 differentially expressed proteins (P3H1 and RCN-3) were validated by Western Blot.@*Conclusions@#Proteomic analysis can identify the proteins with variance of keloid, hypertrophy scar and normal skin. Further investigations of these differential proteins may reveal the pathogenesis of keloid and provide new treatments for it.
ABSTRACT
The impact factors were explored to determine the horizontal positional relationship between the umbilicus and the 2nd lumbar spinal process in adults and to verify the accuracy of the localization of Shenshu (BL 23) via the umbilicus. The position of the umbilicus and the 2nd lumbar spinal process was measured in 100 participants and the data were analyzed through SPSS 20.0 software. It was found that the umbilicus and the 2nd lumbar process were not positioned horizontally. The positional relationship of these two sites was not apparently correlated with gender, age, body weight, body height, BMI, waistline and discomfort of lumbar region. The umbilicus was commonly and posteriorly projected on the site between the 4th and 5th lumbar vertebra. It is explained that the localization of Shenshu (BL23) via the umbilicus is not accurate.

Objective To investigate the effects of paeonol on renin-angiotensin system (RAS) occurred on the development of ventricular remodeling after acute myocardial infarction (AMI) in rats. Methods The left anterior descending coronary artery was ligated to establish the model of AMI in male SD rats. Six groups were set up:sham-operation group, AMI model group, captopril control group, paeonol low dose group (6 mg/kg), paeonol middle dose group (9 mg/kg) and paeonol high dose group (12 mg/kg). Rats were given treatment for 4 weeks after the AMI model was established. HE staining was used to observe changes of myocardial tissue. Real-time PCR was used to detect the mRNA levels of angiotensinogen (AGT), angiotensin Ⅱ receptor type1(AGTR1) and endothelin (ET)-1 of six groups. Western blot assay was used to detect the protein levels of peptidyl-dipeptidase A (ACE), angiotensin Ⅱ(Ang)-Ⅱand AGTR1 in six groups. Results The transcription of AGT, AGTR1, ET-1mRNA and the expressions of ACE, Ang-Ⅱ and AGTR1 protein were significantly higher in myocardial tissue of AMI rats than those of sham-operation rats (P＜0.05). Compared with model group, the expressions of AGT, AGTR1, ET-1mRNA and ACE, Ang-Ⅱ, AGTR1 protein were significantly decreased in paeonol high dose group and captopril control group (P＜0.05). Paeonol reduced the expressions of those mRNA and protein levels in a significant dose dependent manner. Conclusion Paeonol can slow down the deterioration of the ventricular remodeling after AMI in rats, which may be related to the inhibition of over-activation of RAS.
