Background:Helicobacter pylori( Hp)is listed as Group 1 human carcinogen. Transcription factor FOX family plays important role in the development of tumor,and FOXA1 is a key target transcription factor of some microRNAs( miRNAs). Aims:To investigate the relationship of Hp infection with expression of FOXA1 in gastric mucosal tissues. Methods:Eighty patients undergone gastroscopy from Jan. 2014 Sept. 2014 were enrolled. Hp infection was detected by 14 C-urease breath test( 14 C-UBT),modified Giemsa staining and bacterial culture. Expression of FOXA1 in gastric mucosal tissues was determined by immunohistochemical SP method. Results:FOXA1 expression in Hp positive tissues was significantly higher than that in Hp negative tissues(73. 8% vs. 47. 4%;χ2 =4. 81,P<0. 05). Conclusions:High expression of FOXA1 in gastric mucosal tissues suggests that miRNAs pathway may be one of the molecular mechanisms of Hp infection leading to gastric intraepithelial neoplasia even gastric cancer.

Objective:
This study aimed to investigate the impact of molecular classification and PTEN, KRAS and PIK3CA gene mutation on the outcome of fertility-preserving treatment in the patients with endometrioid endometrial cancer (EEC) and endometrial atypical hyperplasia (EAH).
Methods:
This is a single-center retrospective study. A total of 135 patients with EEC and EAH receiving fertility-preserving treatment and molecular classification were reviewed. The distribution of the four types of molecular classification was described. The impact of non-specific molecular profile (NSMP), mismatch repair-deficiency (MMRd), and PTEN, KRAS and PIK3CA gene mutation on the outcome of fertility-preserving treatment was analyzed.
Results:
Of the patients analyzed, 86.7% (117/136) were classified as having NSMP; 14 (10.4%), MMRd; 1 (0.7%), POLEmut EAH; and 3 (2.2%), p53abn EEC. The patients having NSMP and MMRd achieved similar 16-, 32-, and 48-week complete response rates. The patients harboring tier I and tier II PTEN mutations (PTENmut-Clin) achieved lower cumulative 32-week CR rates than those with PTEN-others (without PTENmut-Clin) (22/47, 46.8% vs. 50/74, 67.6%; p=0.023; odds ratio=0.422; 95% confidence interval [CI]=0.199–0.896). Insulin-resistance (hazard ratio [HR]=0.435; 95% CI=0.269–0.702; p=0.001) and PTENmut-Clin (HR=0.535; 95% CI=0.324–0.885; p=0.015) were independent negative predictors for lower 32-week CR rates.
Conclusion
PTENmut-Clin is an independent risk factor for unfavorable fertility-preserving treatment outcomes in the patients with EEC and EAH. The patients with MMRd receiving fertility-preserving treatment achieved outcomes similar to those of the patients with NSMP. The molecular profiles might guide fertility-preserving treatment in the prognosis and clinical decisions.

To analyse the familial aggregation and genetic predisposition of Shen-yin deficiency syndrome (SYDS) in families with diabetes mellitus type 2 (DM2). Methods One hundred and forty-one DM2 patients were collected from 32 family lines in Nanjin area, in which the probands were differentiated as DM2 with SYDS. On them, genetic analysis on the characteristics of SYDS was conducted using pedigree analysis, morbidity and heritability of the first-degree relatives of the probands were calculated, and the action of familial SYDS factor on the genesis of the syndrome was assessed by multiple factors regression analysis. Results The morbidity rate of SYDS in the first-degree relatives of the probands was 33.71%, and the heritability, calculated by Falconer formula, was 80.6%. The fitting result of regression analysis showed that familial factor played an important role in SYDS genesis (OR = 5.61, P = 0.001), but DM2 itself is not an independent risk factor for it. Conclusion DM2 with SYDS shows the tendency of familial aggregation and genetic predisposition, genetic factor is associated with the genesis of the syndrome. Pedigree research is a good method for exploring the relationship between syndrome and genetic factor.

Essential palatal tremor is relatively rare in clinical practice, which manifests involuntary and rhythmic contraction of soft-palate along with auditory click. The cause is unknown and there is no specific treatment at present. This article reports a female patient with essential palatine tremor, who presented with involuntarily beating of soft palate, disappeared during sleep, had sensory tricks, and gradually developed mental and psychological problems such as anxiety disorders. After treatment with integrated traditional Chinese and Western medicine, the symptoms improved. The clinical features of the case were analyzed, relevant literature was reviewed, and the possible etiology and characteristics of the disease were explored, so as to provide reference for clinical diagnosis and treatment.

Objective:To investigate the correlation between triglyceride-glucose (TyG) index and high on-treatment platelet reactivity (HTPR) during clopidogrel treatment in patients with ischemic stroke.Methods:Patients with ischemic stroke who received maintenance dose of clopidogrel (75 mg/d) in the Department of Neurology, Guangdong Provincial Hospital of Chinese Medicine from January 2017 to March 2021 were retrospectively included. The highest quartile (Q4) of the TyG index was defined as insulin resistance. Platelet reactivity was assessed by thromboelastogram and clopidogrel HTPR was defined as the clot strength induced by adenosine diphosphate (MA ADP) >47 mm. Multivariate regression model was used to analyze the independent correlation between TyG index and platelet reactivity. Results:A total of 83 patients were included. The TyG index showed a linear correlation with MA ADP. The patients were divided into 4 groups according to the quartile of TyG index. The incidence of clopidogrel HTPR increased significantly with the increase of the quartile of the TyG index ( Ptrend=0.017). Multivariate analysis showed that there was a significant independent correlation between insulin resistance and clopidogrel HTPR (odds ratio 4.597, 95% confidence interval 1.285-16.446; P=0.019). Conclusions:In patients with ischemic stroke treated with clopidogrel, the incidence of clopidogrel HTPR gradually increases with the increase of the quartile of the TyG index. The insulin resistance assessed by the TyG index is independently associated with clopidogrel HTPR.

The emission of hydrogen sulfide in the waste gas from slaughter plant, fishmeal feed processing and some other food industrial processing could cause serious air pollution to the surrounding environment. The purpose of this study was to screen heterotrophic bacterium strains for the removal of hydrogen sulfide odor. One heterotrophic bacterial mutant ZJNB-B3 was derived from the sulfide degrader Bacillus cereus XJ-2 and its sulfide removal efficiency was 97%. Based on the morphology studies, biochemical tests and 16S rRNA gene analysis, the strain was identified as Bacillus cereus ZJNB-B3. The NCBI GenBank accession number is MF679650. Batch tests showed that the strain tolerated up to 300 mg/L of toxic S²⁻ concentration. Response surface methodology was applied to optimize the conditions of degradation of sulfide. The optimal parameters were as follows: initial sulfide concentration 211.8 mg/L, initial pH 6.72, inoculum volume 5.04%, and incubation temperature 30 ℃. The accumulated sulfate concentration was 63.8 mg/L and the sulfide removal efficiency was 97.3% after 48 h incubation. No sulfuric acid was generated during sulfide oxidation by the strain. Sulfide could be removed effectively by this strain under mild pH conditions. The results suggested that the strain may have great industrial application potential. This study provides the fundamentals for the removal of hydrogen sulfide gas.
