A clinico-pathological study was carried out on 8 patients with microscopic polyar-teritis nodosa (MPAN). It was found that the renal lesions were very common and severe in this group of patients apart from the typical presentation of MPAN, including fever, myalgias, arteritis and the involvement of hematologic, gastrointestinal and cardiovascular systems. Laboratory pictures were characterized by leucocytosis, anemia and increased serum creatinine. The plasma anti-neutrophil cytoplasmic antibodies were present and thought to be of particular importance. On light microscopy, focal, segmental necrotising glomerulonephritis was discovered which was often associated with extensive crescence formation and vasculitis. We recommend renal biopsy as a valuable tool of investigation in the diagnosis of MPAN.

Objective To systematically evaluate the effect of sequence of pulmonary artery and vein transection in thoracoscopic lobectomy on the efficacy and safety of patients with non-small cell lung cancer. Methods PubMed, EMbase, Web of Science, The Cochrane Library, CNKI, Wanfang, VIP and CBM databases were searched for the researches on The post-operative efficacy of pulmonary arteriovenous and pulmonary vein resection sequence in thoracoscopic lobectomy for non-small cell lung cancer. The retrieval time is from the database construction to May 2022. Meta-analysis was performed using RevMan 5.4 software. Results Eight articles were included, including 3 randomized controlled studies and 5 cohort studies, with a total of 1810 patients. Meta-analysis results showed that: The operative time (MD=13.34, 95%CI(7.36, 19.32), P < 0.0001) and intraoperative blood loss (MD=45.29, 95%CI(40.24, 50.35), P < 0.0001) in the group with priority pulmonary vein resection were significantly higher than those in the group with priority pulmonary vein resection. The difference was statistically significant. However, the benefits of OS (HR=1.34, 95%CI (1.12, 1.60), P=0.001) and DFS (HR=1.44, 95%CI(1.18, 1.76), P=0.0003) in the group of priority pulmonary vein transection were significantly better than those in the group of priority pulmonary artery transection, with statistically significant differences. Conclusion Priority pulmonary vein transection during thoracoscopic lobectomy effectively improved patients' OS and DFS, resulting in higher survival benefit for patients with non-small cell lung cancer, but intraoperative bleeding and operation time are more than those with priority pulmonary artery transection.

Objective To investigate the clinical effects and influencing factors of remote ischemic post-conditioning RIPostC in the patients with post stroke fatigue(PSF).Methods Eighty patients with PSF were ran-domly divided into experimental group(n = 40)and control group(n = 40).Patients in both groups received routine drug therapy and rehabilitation training for stroke.The experimental group were additionally given RIPostC for four weeks.They were evaluated with National Institute of Health Stroke Scale(NIHSS),Barthel Index(BI),Mini-mental State Examination(MMSE),fatigue severity scale(FSS),Hamilton Anxiety Scale(HAMA),and Hamilton Depression Scale(HAMD).Results The score of NIHSS,FSS,HAMA and HAMD in the both groups were decreased,while the score of BI and MMSE were increased(P<0.01).The difference in the score of NIHSS,BI,MMSE,FSS,HAMA and HAMD between the two groups before and after treatment showed statistical significance(P<0.01)and the difference in the score was more significant in the experimental group.The risk factors of FSS were MMSE and HAMA.Conclusion RIPostC can effectively improve the neurological deficits,daily activity ability and cog-nitive function,alleviate fatigue,anxiety and depression in the patients of PSF.The influencing factors of PSF are cognitive function and anxiety.

Objective:To investigate the correlations of melanin concentration hormone (MCH) in cerebrospinal fluid (CSF) and serum with sleep disorder, memory dysfunction and prognoses in patients with cerebral ischemic stroke (CIS).Methods:One hundred elderly CIS patients, admitted to Department of Neurology, He'nan Provincial People's Hospital from June 2021 to January 2022 were enrolled as CIS group, and 50 subjects collected from Physical Examination of the same hospital during the same period were enrolled as control group. MCH levels in the CSF and serum were detected by ELISA. Sleep quality was assessed by polysomnography and Pittsburgh Sleep Quality Index (PSQI). Memory function was assessed by Rivermead Behavioral Memory Test 2 nd Edition (BMT-II). Prognoses were assessed by modified Rankin Scale (mRS) 3 months after discharge. The clinical data and MCH levels of the two groups were compared; the differences in MCH levels among CIS patients with different degrees of sleep disorder, and different memory functions and prognoses were compared. Correlations of MCH level and sleep parameters with RBMT-II scores in these CIS patients were analyzed. Results:Compared with that in the control group, the proportion of patients with hypertension in CIS group was significantly higher ( P<0.05). Compared with the control group ([42.39±16.11] pg/mL), the serum MCH level in CIS group ([36.89±15.19] pg/mL) was statistically lower ( P<0.05). In CIS patients, patients with mild or severe sleep disorder had significantly decreased CSF MCH level compared with patients without sleep disorder ( P<0.05), patients with severe sleep disorder had significantly decreased CSF MCH level compared with patients with mild sleep disorder ( P<0.05); patients with severe sleep disorder had significantly decreased serum MCH level compared with patients without sleep disorder ( P<0.05); CSF MCH level was negatively correlated with PSQI scores, sleep latency and wake frequency ( P<0.05), and positively correlated with percentage of rapid eye movement ( P<0.05); serum MCH level in CIS patients was negatively correlated with PSQI scores and wake frequency ( P<0.05). In CIS patients, the CSF and serum MCH levels in patients with memory dysfunction was significantly lower compared with those with normal memory function ( P<0.05); a positive correlation was noted between RBMT-II scores and CSF MCH level ( P<0.05). In CIS patients, patients with poor prognosis had statistically lower CSF and serum MCH levels compared with those with good prognosis ( P<0.05). Conclusion:The serum MCH level in CIS patients is significantly decreased, which is closely related to the occurrence of sleep disorder and memory dysfunction after stroke; and they further affects the prognoses.

Liver fibrosis is the healing reaction of chronic liver injury caused by various factors such as viral infection， alcohol， and chemical substances and is a key link in the progression of chronic liver diseases to liver cirrhosis and liver cancer. Liver macrophages are considered important mediators of liver injury and repair， and the polarization trend of macrophages has a bidirectional regulatory effect on liver fibrosis. This article reviews the role of different phenotypes of liver macrophages in the development and progression of liver fibrosis， in order to provide new ideas for the prevention and treatment of fibrosis.

Since the first case of corona virus disease 2019 (COVID-19) caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) at the end of 2019, the virus has spread rapidly around the world and has become a global public health problem. In the process of this virus epidemic, compared with the general population, cancer patients are considered to be highly susceptible people, especially the lung cancer patients. Some studies have shown that angiotensin converting enzyme 2 (ACE2) may be the pathway for SARS-CoV-2 to infect the host. At the same time, ACE2 is often abnormally expressed in non-small cell lung cancer. Therefore, understanding the respective mechanisms of ACE2 in COVID-19 and non-small cell lung cancer has extremely important reference value for the study of vaccines and therapeutic drugs, and also provides meaningful guidance for the protection of patients with lung cancer during the epidemic. This article reviews the possible invasive mechanism of ACE2 in SARS-CoV-2 and its abnormal expression in non-small cell lung cancer.

Objective    To systematically evaluate the efficacy and safety of jejunostomy tube versus nasojejunal tube for enteral nutrition after radical resection of esophageal cancer. Methods    PubMed, EMbase, Web of Science, The Cochrane Library, CNKI, Wanfang, VIP and CBM databases were searched to collect the clinical effects of jejunostomy tube versus nasojejunal nutrition tube after radical resection of esophageal cancer from inception to October 2021. Meta-analysis was performed using RevMan 5.4 software. Results    Twenty-six articles were included, including 17 randomized controlled studies and 9 cohort studies, with a total of 35 808 patients. Meta-analysis results showed that: in the jejunostomy tube group, the postoperative exhaust time (MD=–4.27, 95%CI –5.87 to –2.66, P=0.001), the incidence of pulmonary infection (OR=1.39, 95%CI 1.06 to 1.82, P=0.02), incidence of tube removal (OR=0.11, 95%CI 0.04 to 0.30, P=0.001), incidence of tube blockage (OR=0.47, 95%CI 0.23 to 0.97, P=0.04), incidence of nasopharyngeal discomfort (OR=0.04, 95%CI 0.01 to 0.13, P=0.001), the incidence of nasopharyngeal mucosal damage (OR=0.13, 95%CI 0.04 to 0.42, P=0.008), the incidence of nausea and vomiting (OR=0.20, 95%CI 0.08 to 0.47, P=0.003) were significantly shorter or lower than those of the nasojejunal tube group. The postoperative serum albumin level (MD=5.75, 95%CI 5.34 to 6.16, P=0.001) was significantly better than that of the nasojejunal tube group. However, the intraoperative operation time of the jejunostomy tube group (MD=13.65, 95%CI 2.32 to 24.98, P=0.02) and the indent time of the postoperative nutrition tube (MD=17.81, 95%CI 12.71 to 22.91, P=0.001) were longer than those of the nasojejunal nutrition tube. At the same time, the incidence of postoperative intestinal obstruction (OR=6.08, 95%CI 2.55 to 14.50, P=0.001) was significantly higher than that of the nasojejunal tube group. There were no statistical differences in the length of postoperative hospital stay or the occurrence of anastomotic fistula between the two groups (P>0.05). Conclusion    In the process of enteral nutrition after radical resection of esophageal cancer, jejunostomy tube has better clinical treatment effect and is more comfortable during catheterization, but the incidence of intestinal obstruction is higher than that of traditional nasojejunal tube.

OBJECTIVE To provide evidence for the safe clinical application of Trastuzumab for injection. METHODS Reports of adverse drug reaction （ADR） related to Trastuzumab for injection submitted in Beijing from June 2018 to May 2023 were collected. Statistical analyses were performed using SPSS 25.0 software. The gender and age of patients with ADRs， outcome， types of cancer， and the time of onset， severity， affected organs/systems of ADRs were included for analyses. The univariate Logistic regression analysis was conducted on patient fever and ADR prognosis. RESULTS A total of 195 patients with 318 instances of ADRs were included in the study. Women （87.69%） and patients aged 60-69 （33.85%） were more likely to experience ADRs. Breast cancer dominated （86.67%） in terms of cancer types； in terms of outcomes， most patients （67.69%） showed improvement， and some patients （27.69%） achieved full recovery. Overall， 68.72% of ADRs mainly occurred on the day of medication， and 95.38% of ADRs were of “moderate” severity. The most affected organs/systems were general diseases and various reactions at the administration site （40.57%）， with chills （18.87%） and fever （18.24%） being the most common. Univariate Logistic regression analysis showed that fever mostly occurred within 1 day of medication （OR＝5.63， 95%CI was 2.26-14.02， P＜ 0.001）. The time of onset of ADR greater than 1 day was a risk factor for poor ADR prognosis （OR＝20.08， 95%CI was 2.45- 164.43， P＝0.005）， mainly manifesting as bone marrow suppression and liver function abnormalities. Neutrophilia， cardiorespiratory arrest， and mixed liver damage were new ADRs not recorded in the drug’s instructions. CONCLUSION Women and patients aged ≥60 are high-risk groups for ADRs of Trastuzumab for injection. Chills and fever remain the most common ADRs of this drug， and these symptoms mostly occur within 1 day of medication， which have better prognoses. Close attention should be paid to the patient’s temperature changes on the day of drug infusion， with timely intervention. Regular monitoring of the patient’s hematological indicators is necessary to detect any bone marrow suppression and liver function abnormalities after medication.

Objective    To systematically evaluate the application effect of CT-guided Hook-wire localization and CT-guided microcoil localization in pulmonary nodules surgery. Methods    The literatures on the comparison between CT-guided Hook-wire localization and CT-guided microcoil localization for pulmonary nodules were searched in PubMed, EMbase, The Cochrane Library, Web of Science, Wanfang, VIP and CNKI databases from the inception to October 2021. Review Manager (version 5.4) software was used for meta-analysis. The Newcastle-Ottawa Scale (NOS) was used to evaluate the quality of studies. Results    A total of 10 retrospective cohort studies were included, with 1 117 patients including 473 patients in the CT-guided Hook-wire localization group and 644 patients in the CT-guided microcoil localization group. The quality of the studies was high with NOS scores>6 points. The result of meta-analysis showed that the difference in the localization operation time (MD=0.14, 95%CI −3.43 to 3.71, P=0.940) between the two groups was not statistically significant. However, the localization success rate of the Hook-wire group was superior to the  microcoil group (OR=0.35, 95%CI 0.17 to 0.72, P=0.005). In addition, in comparison with Hook-wire localization, the microcoil localization could reduce the dislocation rate (OR=4.33, 95%CI 2.07 to 9.08, P<0.001), the incidence of pneumothorax (OR=1.62, 95%CI 1.12 to 2.33, P=0.010) and pulmonary hemorrhage (OR=1.64, 95%CI 1.07 to 2.51, P=0.020). Conclusion    Although Hook-wire localization is slightly better than microcoil localization in the aspect of the success rate of pulmonary nodule localization, microcoil localization has an obvious advantage compared with Hook-wire localization in terms of controlling the incidence of dislocation, pneumothorax and pulmonary hemorrhage. Therefore, from a comprehensive perspective, this study believes that CT-guided microcoil localization is a preoperative localization method worthy of further promotion.
