This paper mainly introduces a rare special subtype of gastric cancer , the stomach hepatoid adenocarcinoma .This kind of adenocarcinoma in pathogenesis ,pathology ,treatment and prognosis has great differ-ence from traditional stomach cancer .Because it has both characteristics of gastric carcinoma and hepatocellular carcinoma,and is easily to result in missed diagnosis and misdiagnosis in clinic .It is necessary for us to distin-guish hepatoid adenocarcinoma of the stomach and gastric carcinoma .We may further improve the diagnosis rate of hepatoid adenocarcinoma of the stomach ,and reduce its mortality rate ,prolong the survival period .

Objective:To study influence of renal sympathetic denervation (RDN)on cardiac function of dogs with heart failure (HF).Methods:A total of 40 dogs were randomly and equally divided into RDN group [received bilat- eral renal artery radiofrequency ablation (RFA)]and model group (only received femoral puncture).Pacemaker was implanted in every dog,and dog HF model was established using rapid right ventricular pacing.Cardiac and re-nal function indexes,BNP and sympathetic activity index levels were observed and compared between two groups be- fore RFA/sham operation,instant and four weeks after model establishment.Results:After operation four weeks, compared with model group,there were significant reductions in levels of epinephrine (E)[(362.69±42.54)ng/ml vs.(290.36±42.32)ng/ml],renin (R)[(305.46± 39.68)ng/ml vs.(230.04±32.80)ng/ml],aldosterone (AD)[(408.00±38.56)ng/ml vs.(246.00± 48.37)ng/ml],angiotensin Ⅱ (ATⅡ)[(280.00±48.08)pg/ml vs.(172.00±25.04)pg/ml]and norepinephrine (NE)[(425.65±50.54)ng/ml vs.(316.76±46.29)ng/ml]in RDN group (P<0.05 all);there were significant reductions in HR,respiratory rate (RR)and BNP level in RDN group,P<0.05 all;there were significant rise in SBP,LVEF,CO,CI,left ventricular pressure maximal rising rate (+dp/dtmax),left ventricular pressure maximal dropping rate (-dp/dtmax)and left ventricular end-systolic pressure (LVESP),and significant reductions in left ventricular end-systolic dimension (LVESd),left ventricular end-diastolic dimension (LVEDd)and left ventricular end-diastolic pressure (LVEDP)in RDN group,P<0.05 all.Conclusion:RDN can decrease renal sympathetic activity,improve heart function,inhibit myocardial remode- ling,its therapeutic effect is significant

Objective To evaluate the therapeutic effect of modifiedHuanglian-Jiedudecoction for resistant hypertension and explore its possible mechanism.Methods A total of 90 patients with resistant hypertension were recruited and randomly divided into a treatment group and a control group, 45 patients in each group. The control group was treated with oral administration of irbesartan and hydrochlorothiazide tablets and controlled-release nifedipine tablets, while the treatment group was further added modifiedHuanglian-Jiedu decoction for 4 weeks. Plasma endothelin (ET) and calcitonin gene-related peptide (CGRP) were measured by radioimmunoassay.Rusults The total efficiency according to the TCM syndrome in the treatment group was 86.7%(39/45) which was higher than 64.4%(29/45) in the control group(χ2=4.873,P=0.027). The systolic blood pressure (SBP) and diastolic blood pressure (DBP) decreased after the treatment in both groups ( SBP in the treatment group: 119.26 ± 9.34 mmHgvs.172.11 ± 10.52 mmHg,t=25.201,P<0.01; DBP in the treatment group: 78.18 ± 7.21 mmHgvs.111.12 ± 11.16 mmHg,t=16.631, P<0.01; SBP in the control group: 145.21 ± 7.56 mmHgvs.171.32 ± 11.15 mmHg,t=13.002,P<0.01; DBP in the control group: 93.57±8.13 mmHgvs. 109.89 ± 12.21 mmHg,t=7.463,P<0.01), while the decrease of SBP (t=14.487,P<0.01) and DBP (t=9.501, P<0.01) in the treatment group was more greater than those in the control group. The control rate of blood pressure in the treatment and control groups were 73.3% (33/45) and 55.6% (25/45), respectively, there had no significant difference (χ2=2.376,P=0.123). The plasma ET in the treatment group was significantly decreased than that in the control group (75.68 ± 10.67 ng/Lvs.112.79 ± 12.26ng/L;t=15.317,P<0.05), and CGRP significantly increased (49.87 ± 4.75 ng/Lvs.33.87 ± 7.89 ng/L;t=11.654,P<0.05).Conclusion Modified Huanglian-Jiedudecoction may have some therapeutic effect for resistant hypertension, its mechanism may be involved in ET decreasing and CGRP increasing.

Testicular adrenal rest tumor (TART) is frequently complicated by congenital adrenal hyperplasia, which is a benign tumor of the testes frequently found in adolescents and adults.Palpation and scrotal ultrasound are the main diagnostic methods for TART.Poorly managed TART often results in testicular dysfunction or even infertility due to tumor compression.This article reviews the pathogenesis, epidemiology, clinical features, diagnosis, differential diagnosis and treatment of TART, thus improving the understanding of the disease to achieve early diagnosis, early treatment, and improved prognosis.

Objective:To summarize the clinical features and prognosis of Budd-Chiari syndrome with hepatopulmonary syndrome (HPS) in children.Methods:The clinical data of a child who had Budd-Chiari syndrome with HPS treated at the Department of Pediatrics of the First Affiliated Hospital of Zhengzhou University in December 2016 was analyzed retrospectively. Taking "Budd-Chiari syndrome" and "hepatopulmonary syndrome" in Chinese or English as the keywords, literature was searched at CNKI, Wanfang, China Biomedical Literature Database and PubMed up to July 2023. Combined with this case, the clinical characteristics, diagnosis, treatment and prognosis of Budd-Chiari syndrome with HPS in children under the age of 18 were summarized.Results:A 13-year-old boy, presented with cyanosis and chest tightness after activities for 6 months, and yellow staining of the skin for 1 week. Physical examination at admission not only found mild yellow staining of the skin and sclera, but also found cyanosis of the lips, periocular skin, and extremities. Laboratory examination showed abnormal liver function with total bilirubin 53 μmol/L, direct bilirubin 14 μmol/L, and indirect bilirubin 39 μmol/L, and abnormal blood gas analysis with the partial pressure of oxygen of 54 mmHg (1 mmHg=0.133 kPa), the partial pressure of carbon dioxide of 31 mmHg, and the alveolar-arterial oxygen gradient of 57 mmHg. Hepatic vein-type Budd-Chiari syndrome, cirrhosis, and portal hypertension were indicated by abdominal CT venography. Contrast-enhanced transthoracic echocardiography (CE-TTE) was positive. After symptomatic and supportive treatment, this patient was discharged and received oxygen therapy outside the hospital. At follow-up until March 2023, there was no significant improvement in hypoxemia, accompanied by limited daily activities. Based on the literature, there were 3 reports in English while none in Chinese, 3 cases were reported. Among a total of 4 children, the chief complaints were dyspnea, cyanosis, or hypoxemia in 3 cases, and unknown in 1 case. There were 2 cases diagnosed with Budd-Chiari syndrome with HPS at the same time due to respiratory symptoms, and 2 cases developed HPS 1.5 years and 8.0 years after the diagnosis of Budd-Chiari syndrome respectively. CE-TTE was positive in 2 cases and pulmonary perfusion imaging was positive in 2 cases. Liver transplantation was performed in 2 cases and their respiratory function recovered well; 1 case received oxygen therapy, with no improvement in hypoxemia; 1 case was waiting for liver transplantation.Conclusions:The onset of Budd-Chiari syndrome with HPS is insidious. The most common clinical manifestations are dyspnea and cyanosis. It can reduce misdiagnosis to confirm intrapulmonary vascular dilatations with CE-TTE at an early stage. Liver transplantation is helpful in improving the prognosis.

Objective:To explore the characteristics of cervical lesions in female patients in the Shihezi region of Xinjiang in the past two years and provide guidance for clinical work and local cervical cancer screening.Methods:The clinicopathological data and characteristics of 1 080 patients with abnormal double screening of human papilloma virus (HPV) and cervical exfoliative cell test (TCT) and vaginal mirror cervical tissue biopsy in the gynecology department of the First Affiliated Hospital of Medical College of Shihezi University from May 2017 to March 2019 were analyzed retrospectively. The influencing factors of cervical lesions were analyzed by logistic regression.Results:(1) Uneducated [odds ratio ( OR)=2.267], irregular vaginal bleeding ( OR=3.275) and number of sexual partners ≥3 ( OR=3.052) were independent risk factors for cervical lesions. (2) Cervical intraepithelial neoplasia (CIN) was detected most frequently in the 30-39 age group (57.54%), and cervical cancer was detected most frequently in the ≥60 age group (14.15%), followed by the 40-49 age group (2.20%). (3) The proportion of HPV positive and the positive rate of high-risk HPV16/18 in the 40-49 age group were the highest, 33.18% and 39.38% respectively. There was no statistically significant difference in HPV viral load between the different age groups ( P>0.05). (4) The detection rates of CIN3 and cervical cancer were higher in the HPV16/18-positive group than in the HPV-positive and TCT≥atypical squamous epithelial cells of undermined significance (ASC-US) group (18.34% vs 11.33%, 4.30% vs 1.82%), with statistically significant difference (all P<0.05), respectively. The detection rate of CIN2 was higher in the high-load group (28.44%) than in the medium-load group (25.32%) and the low load group (15.79%). (5) The detection rate of CIN3 in the HPV-positive TCT for the ASC-US populations was significantly higher in the HPV16/18-positive group than in the other subtypes of HPV-positive group (21.43% vs 8.33%, P<0.05). Conclusions:During cervical cancer screening in Shihezi region, we should strengthen the publicity of elderly women and uneducated people. CIN and cervical carcinoma in Shihezi region are closely associated with high-risk HPV infection, especially HPV16/18 infection. HPV-positive age is mainly concentrated in the age group of 40-49 years, and the detection rate of CIN and cervical cancer is the highest in the age group of 30-39 years and ≥60 years, respectively. The detection rate of ≥CIN2 in HPV16/18 fraction and high viral load population is higher than that of other HPV subtypes positive and low to medium load populations. How to effectively shunt HPV positive TCT is an important problem in ASC-US population, which needs further research.

Cognitive impairment is a kind of senile disease that leads to the decline of personality and behavior ability of the elderly,which seriously affects the quality of daily life of patients.The prevalence rate of the disease increases year by year with the acceleration of the aging process of the society,and its incidence is affected by many risk factors.At this stage,the curative effect for middle and advanced patients is poor.So early identification and intervention to delay the progression of cognitive impairment have become the focus of relevant research.Blood pressure variability can lead to damage of target organs such as heart,brain tissue and kidney,which is closely related to cognitive impairment.In order to expand a new perspective of early intervention in cognitive impairment,this paper reviews the effects of blood pressure variability on different cognitive impairment and its possible pathogenic mechanism.

The oral cavity of each person is home to hundreds of bacterial species.While taxa for oral diseases have been studied using culture-based characterization as well as amplicon sequencing,metagenomic and genomic information remains scarce compared to the fecal microbiome.Here,using metagenomic shotgun data for 3346 oral metagenomic samples together with 808 published samples,we obtain 56,213 metagenome-assembled genomes(MAGs),and more than 64％of the 3589 species-level genome bins(SGBs)contain no publicly available genomes.The resulting genome collection is representative of samples around the world and contains many genomes from candi-date phyla radiation(CPR)that lack monoculture.Also,it enables the discovery of new taxa such as a genus Candidatus Bgiplasma within the family Acholeplasmataceae.Large-scale metagenomic data from massive samples also allow the assembly of strains from important oral taxa such as Por-phyromonas and Neisseria.The oral microbes encode genes that could potentially metabolize drugs.Apart from these findings,a strongly male-enriched Campylobacter species was identified.Oral sam-ples would be more user-friendly collected than fecal samples and have the potential for disease diagnosis.Thus,these data lay down a genomic framework for future inquiries of the human oral microbiome.

Lung transplantation is currently the only recognized effective treatment for end-stage lung disease and has improved the quality of life for patients. However, lung transplantation still faces many challenges, including rejection, infection, post-transplant acute kidney injury, post-transplant diabetes mellitus, ischemia-reperfusion injury and donor shortage, etc. Chinese lung transplantation scholars made a series of important progress in the field of clinical research in 2024, focusing on the study and solution of the above problems, and providing new ideas for lung transplantation surgery. This article systematically reviews the clinical research and technological innovation in the field of lung transplantation in 2024, summarizes the achievements of clinical research in the field of lung transplantation in China in 2024, and aims to providing new directions and strategies for future research.

Lung transplantation is the optimal treatment for end-stage lung diseases and can significantly improve prognosis of the patients. However, postoperative complications such as infection, rejection, ischemia-reperfusion injury, and other challenges (like shortage of donor lungs) , limit the practical application of lung transplantation in clinical practice. Chinese research teams have been making continuous efforts and have achieved breakthroughs in basic research on lung transplantation by integrating emerging technologies and cutting-edge achievements from interdisciplinary fields, which has strongly propelled the development of this field. This article will comprehensively review the academic progress made by Chinese research teams in the field of lung transplantation in 2024, with a focus on the achievements of Chinese teams in basic research on lung transplantation. It aims to provide innovative ideas and strategies for key issues in the basic field of lung transplantation and to help China's lung transplantation cause reach a higher level.
