Evaluation of Efficacy and Prognosis Analysis of Stage III-IV SMARCA4-deficient Non-small Cell Lung Cancer Treated by PD-1 Immune Checkpoint Inhibitors plus Chemotherapy and Chemotherapy / 中国肺癌杂志

BACKGROUND@#The SMARCA4 mutation has been shown to account for at least 10% of non-small cell lung cancer (NSCLC). In the present, conventional radiotherapy and targeted therapy are difficult to improve outcomes due to the highly aggressive and refractory nature of SMARCA4-deficient NSCLC (SMARCA4-DNSCLC) and the absence of sensitive site mutations for targeted drug therapy, and chemotherapy combined with or without immunotherapy is the main treatment. Effective SMARCA4-DNSCLC therapeutic options, however, are still debatable. Our study aimed to investigate the efficacy and prognosis of programmed cell death 1 (PD-1) immune checkpoint inhibitors (ICIs) in combination with chemotherapy and chemotherapy in patients with stage III-IV SMARCA4-DNSCLC.@*METHODS@#46 patients with stage III-IV SMARCA4-DNSCLC were divided into two groups based on their treatment regimen: the chemotherapy group and the PD-1 ICIs plus chemotherapy group, and their clinical data were retrospectively analyzed. Efficacy assessment and survival analysis were performed in both groups, and the influencing factors for prognosis were explored for patients with SMARCA4-DNSCLC.@*RESULTS@#Male smokers are more likely to develop SMARCA4-DNSCLC. There was no significant difference in the objective response rate (76.5% vs 69.0%, P=0.836) between chemotherapy and the PD-1 ICIs plus chemotherapy or the disease control rate (100.0% vs 89.7%, P=0.286). The one-year overall survival rate in the group with PD-1 ICIs plus chemotherapy was 62.7%, and that of the chemotherapy group was 46.0%. The difference in median progression-free survival (PFS) between the PD-1 ICIs plus chemotherapy group and the chemotherapy group was statistically significant (9.3 mon vs 6.1 mon, P=0.048). The results of Cox regression analysis showed that treatment regimen and smoking history were independent influencing factors of PFS in patients with stage III-IV SMARCA4-DNSCLC, and family history was an individual influencing factor of overall survival in patients with stage III-IV SMARCA4-DNSCLC.@*CONCLUSIONS@#Treatment regimen may be a prognostic factor for patients with SMARCA4-DNSCLC, and patients with PD-1 ICIs plus chemotherapy may have a better prognosis.

Correlation Analysis between Thyroid Function Abnormality and Efficacy in Patients with Advanced Non-small Cell Lung Cancer after Immunotherapy / 中国肺癌杂志

BACKGROUND@#Thyroid function abnormality (TFA) is one of the common adverse reactions in patients with advanced non-small cell lung cancer (NSCLC) treated with immunotherapy, but the risk factors of TFA and its relationship with efficacy are not completely clear. The purpose of this study was to explore the risk factors of TFA and its relationship with efficacy in patients with advanced NSCLC after immunotherapy.@*METHODS@#The general clinical data of 200 patients with advanced NSCLC in The First Affiliated Hospital of Zhengzhou University from July 1, 2019 to June 31, 2021 were collected and analyzed retrospectively. χ² test and multivariate Logistic regression were used to explore the risk factors of TFA. Kaplan-Meier curve was drawn and Log-rank test was used for comparison between groups. Univariate and multivariate Cox analysis was used to explore the efficacy factors.@*RESULTS@#A total of 86 (43.0%) patients developed TFA. Logistic regression analysis showed that Eastern Cooperative Oncology Group Performance Status (ECOG PS), pleural effusion and lactic dehydrogenase (LDH) were factors influencing TFA (P<0.05). Compared with normal thyroid function group, the median progression-free survival (PFS) of patients in the TFA group was significantly longer (19.0 months vs 6.3 months, P<0.001), and the objective response rate (ORR) (65.1% vs 28.9%, P=0.020) and disease control rate (DCR) (100.0% vs 92.1%, P=0.020) of the TFA group were better than those of the normal thyroid function group. Cox regression analysis showed that ECOG PS, LDH, cytokeratin 19 fragment (CYFRA21-1) and TFA were factors influencing prognosis (P<0.05).@*CONCLUSIONS@#ECOG PS, pleural effusion and LDH may be risk factors affecting the occurrence of TFA and TFA may be a predictor of the efficacy of immunotherapy. Patients with advanced NSCLC who have TFA after immunotherapy may obtain better efficacy.

Clinical efficacy of the Guanxinning tablet for stable angina pectoris in the elderly and its effects on molecular markers of the prethrombotic state / 中华老年医学杂志

Objective:To investigate the clinical efficacy of the Guanxinning tablet on the prethrombotic state in older adults with stable angina pectoris.Methods:In this study, 80 elderly patients with coronary heart disease and blood stasis admitted to our hospital between December 2019 and December 2021 were selected as the study subjects, and were randomly divided into a control group and an observation group(40 cases each). The control group was treated with Aspirin alone, and the observation group was treated with the Guanxinning tablet in addition to aspirin.Differences in traditional Chinese medicine(TCM)syndrome scores, weekly angina attacks and intervals between attacks, von Willebrand factor(vWF), thrombomodulin(TM), and granule membrane protein-140(GMP-140)levels between the two groups were compared.Results:There was no statistically significant difference in TCM syndrome scores between the observation group and the control group before treatment(11.34±2.2 vs.11.8±2.3, t=0.184, P=0.856), but there was a statistically significant difference between the observation group and the control group after treatment(6.5±1.8 vs.8.4±2.0 points, t=4.230, P=0.000). The number of weekly angina attacks and the interval between attacks in the observation group were significantly decreased compared with the control group, and the difference was statistically significant(all P<0.01). The levels of molecular markers of the prethrombotic state(vWF, TM and GMP-140)in the observation group were more favorable than those in the control group, with statistical significance(all P<0.05). Conclusions:The Guanxinning tablet can improve angina pectoris symptoms in elderly patients with coronary heart disease and effectively improve the expression of molecular markers of the prethrombotic state.

The immune modulation of Th17 and its related cytokines in inflammatory bowel diseases / 中国医师杂志

Inflammatory bowel diseases (IBD) are a kind of non-specific inflammatory disease that occurs in gastrointestinal tract. Abnormal immune regulation is a key factor in its pathogenesis. The acquired immune regulation is mediated by helper T cells (Th), which is reported to play an important role in the pathogenesis of IBD. Th17 is a subtype of CD4 + T cells that could specifically produce interleukin-17 (IL-17) and other related cytokines. In this paper, we review the immune modulation of Th17 and its related cytokines in IBD.

Objective:To investigate the clinical features of patients with anti-N-methyl-D-aspartate receptor (NMDAR) encephalitis misdiagnosed as mental disorder, improve the early diagnosis rate and reduce misdiagnosis.Methods:The clinical data of patients with anti-NMDA receptor encephalitis diagnosed at the First Affiliated Hospital of Zhengzhou University from 2012 to 2018 were collected. Patients misdiagnosed as mental disorders were screened out. Their psychiatric symptom characteristics, disease course characteristics, imaging and laboratory findings, treatment and prognosis were retrospectively analyzed.Results:A total of 121 cases of anti-NMDA receptor encephalitis were collected, and 43 cases of mental disorders were screened out. Sixteen of the 43 patients (37.2%) had prodromal symptoms, and all the patients had psychiatric behavioral abnormalities (100%), including 32 cases (74.4%) of seizures, 13 cases (30.2%) of decreased level of consciousness, 21 cases (48.8%) of involuntary movements, 15 cases (34.9%) of decreased memory, 8 cases (18.6%) of speech dysfunction, and 8 cases (18.6%) of other neurological symptoms (central hyperventilation, autonomic dysfunction). Memory loss was observed in 15 cases (34.9%), speech dysfunction in 8 cases (18.6%), other neurological symptoms (central hypoventilation, autonomic dysfunction) in 8 cases (18.6%), and various symptoms may appear simultaneously or successively in the same patient. Thirty-eight cases had complete resolution of symptoms or only minor physical impairment, and 5 cases had recurrent admissions with mental abnormalities and seizures. The recurrence rate accounted for 11.6% (5/43).Conclusions:The clinical manifestations of anti-NMDA receptor encephalitis are complex and varied. Most of them have mental behavior abnormalities as the first symptom, which is easily misdiagnosed as mental disorder and delayed treatment will lead to prolonged disease course and poor prognosis.

Objective:To investigate therole of serum amylase elevation in the evaluation of diabetic ketoacidosis (DKA) patients and the related factors affecting serum amylase (AMS) levels in patients with diabetic ketoacidosis.Methods:A total of 249 patients with DKA who were admitted to the First Affiliated Hospital of Zhengzhou University from November 2011 to August 2018 were selected for this retrospective study. The patients were divided into the normal group ( n=176) and the elevated group ( n=73) according to the AMS level measured by fasting venous blood samples. The enumeration data such as sex, type of DM, diabetic vascular complications, number of deaths, number of ICU monitoring, and number of acute pancreatitis (AP) after discharge were analyzed by chi-square test or Fisher test, and the measurement data such as age, pH, HbA1c, CO 2CP, Ca 2+, BUN, and Scr were analyzed by independent sample t test to compare the difference between the two groups. Results:The intensive care unit (ICU) monitoring rate was 50.7%, the median length of stay in ICU was 4 days, the median length of hospital stay was 14 days, and the median treatment cost was 28 000 yuan, which were higher in the elevated group than those in the normal group ( P<0.05). There were no significant differences in mortality, AP during hospitalization, and the probability of AP after discharge between the elevated group and the normal group ( P>0.05). The duration of diabetes, the number of previous DKA, the incidence of diabetic vascular complications, HbA1c, pH, BUN, and Scr in the elevated group were all higher than those in the normal group ( P<0.01 or P<0.05). Conclusions:DKA patients with elevated AMS are more likely to be admitted to ICU, and the length of stay in ICU, total length of hospital stay and total cost of treatment are all increased. Where as the overall mortality rate during hospitalization and the likelihood of AP after discharge are not increased.

Establishment of human gastric cancer model in normal immune mice based on micro-carrier 6 / 中国肿瘤临床

Objective:To establish a mouse model of gastric cancer by inoculating MKN45 cells into mice with normal immune function utilizing microcarrier technology. Methods:A total of 60 male C57BL/6 mice were randomly divided into three groups, namely, 2D, con-trol, and 3D groups, according to the coculture system of MKN45 and microcarrier. The mouse models of gastric carcinoma were estab-lished by hypodermic injection. The time of tumorigenesis, rate of tumor formation, and pathological features were observed in each group. Results:In the 3D group, the time of tumor formation was short, whereas the rate of tumor formation was high (80%). No de-tectable tumor formations were observed in the 2D and control groups. HE and immunohistochemical staining of the transplantation tumor model showed evident characteristics of human gastric cancer. Conclusion:A human gastric cancer model in normal immune mice was successfully established. The onset and development mechanism of gastric cancer could be more effectively investigated in mice with normal immune function through this model. Moreover, a more valuable and new animal model for the research and devel-opment of anticancer drug was established.

Expression and prognostic significance of ANRIL in hepatocellular carcinoma / 中华普通外科杂志

Objective To investigate the expression level of antisense non-coding RNA in the INK4 locus (ANRIL) in hepatocellular carcinoma (HCC) tissues and to evaluate its relation to clinicopathological features and prognosis of HCC.Methods Quantitative real-time polymerase chain reaction (qRT-PCR) method was used to detect the expression of ANRIL in HCC tissues and adiacent tissues (n =90) and to analyze its relationship with clinicopathological data.Kaplan-Meier curves and multivariate Cox proportional models were used to study the impact on clinical outcome.Small interfering RNA (siRNA) was used to silence ANRIL and to explore the effects of reduced ANRIL expression on cell growth and metastasis.Results ANRIL expression in HCC tissues was significantly higher than in the adjacent non-tumor tissues (t =13.083,P ＜ 0.05).The expression of ANRIL was remarkably associated with the histologic grade (x2 =40.724,P ＜ 0.05) and TNM stage (x2 =43.245,P ＜ 0.05).The mean survival time of the patients with high ANRIL was 18.2 months (95％ CI:14.9-21.5 months),shorter than 39.4 months (95％ CI:35.5-43.4 months) in low expression (x2 =47.590,P ＜0.05).Multivariate analysis suggested that high ANRIL expression was an independent predictor of poor prognosis (HR =2.143,95％ CI:1.083-4.243,P ＜ 0.05).Decreased expression of ANRIL could suppress the cell proliferation,migration and invasion of HCC cells.Conclusion Positive ANRIL expression is negatively correlated with the prognosis of HCC patients.

Analysis of the therapeutic effect of interventional embolization and surgical clipping for the treatment of posterior communicating artery aneurysms / 介入放射学杂志

Objective To analyze the complications and clinical effects of interventional embolization and surgical clipping for the treatment of posterior communicating artery aneurysms, and to compare the results between the two methods.Methods A total of 90 patients with confirmed posterior communicating artery aneurysm, who were admitted to the Second Affiliated Hospital of Zhengzhou University during the period from August 2013 to March 2015, were enrolled in this study. Of the 90 patients, 49 received interventional embolization therapy (interventional embolization group) and 41 underwent surgical clipping treatment (surgical clipping group). Before the treatment the patient's condition was evaluated according to Hunt-Hess classification, after the treatment the therapeutic effect was assessed with Glasgow prognosis scale (GOS). The postoperative GOS scores and complications in patients with different Hunt-Hess classification were compared between the two groups. Results In patients of Hunt-Hess 0-Ⅲ grade, no statistically significant differences in postoperative GOS scores existed between the interventional embolization group and the surgical clipping group (t=0.842,P>0.05), while the postoperative GOS scores in patients of Hunt-HessⅣgrade of the interventional embolization group was remarkably higher than that in patients of Hunt-HessⅣgrade of the surgical clipping group, the difference was statistically significant (t=1.713,P<0.05). The incidence of complications in the interventional embolization group was significantly lower than that in the surgical clipping group (x2=1.036,P<0.05). Conclusion For the treatment of Hunt-Hess 0-Ⅲgrade posterior communicating artery aneurysms, the interventional embolization and the surgical clipping show no difference in their therapeutic effects; while for the treatment of Hunt-Hess Ⅳ grade posterior communicating artery aneurysms, the interventional embolization in superior to the surgical clipping, as the interventional embolization carries lower operation risk and complication incidence, and it also has reliable effect.

Perioperative glycosylated haemoglobin concentrations and glucose levels in Roux-en-Y gastric bypass GK rats / 中华普通外科杂志

Objective To analyze the related factors associated with the effect of Roux-en-Y gastric bypass in Goto-Kakizaki rats.Methods In GK rats undergoing Roux-en-Y gastric bypass,the weight,food intake,and the fasting blood glucose were retrospectively analyzed before surgery and 1,3,6,12,24 weeks after surgery,and the glycosylated haemoglobin concentrations were retrospectively analyzed before surgery and 4,12,24 weeks after surgery.According to preoperative glycosylated haemoglobin concentrations,GK rats were divided into 3 groups(group A,HbAlc 6.5％-7.9％; group B,HbAlc 8.0％-9.9％ ; group C,HbAlc ＞ 10％).Results The fasting blood glucose and the glycosylated haemoglobin concentrations significantly decreased 1 week after surgery(P ＜ 0.01),on 24 weeks after operation,the fasting blood glucose levels decreased from(12.1 ± 3.0)mmol/L to(7.6 ± 1.3)mmol/L,and the glycosylated haemoglobin concentrations declined from(9.2％ ± 1.8％)to(6.3％ ± 0.8％).Preoperative fasting blood glucose was(11.1 ± 2.2)mmol/L and(15.8 ± 2.3)mmol/L respectively,and the preoperative glycosylated haemoglobin concentration was(8.6％ ± 1.4％)and(11.5％ ± 1.4％)respectively(P ＜ 0.01).Non-conditional Logistic regression analysis identified preoperative glycosylated haemoglobin concentrations as an independent predictor for the cure rate(P ＜ 0.01); Differences were significant between group A and group C,and group B and group C on the efficiency of the surgery(P ＜0.01).Conclusions Significant correlation established between glycosylated haemoglobin concentrations and the efficiency of the surgery,especially for those rats with preoperative HbAlc ＜ 10％.

Influence of Amlodipine besylate/atorvastatin calcium on atherosclerosis level in elderly with hypertension and hyperlipemias / 中华老年医学杂志

Objective To investigate influence of amlodipine /atorvastatin on atherosclerosis in the elderly with hypertension and hyperlipidemia.Methods Totally 108 cases with hypertension and hyperlipidemia in our hospital were randomly divided into control group and observation group (n =54 each).The control group received conventional antihypertensive treatment such as diuretics,angiotensin-converting enzyme inhibitors,calcium antagonists; the observation group received amlodipine and atorvastatin combination tablet as add-on therapy to the above drugs for 6 months.The blood lipid level and carotid artery ultrasound detection results were observed and compared between the two groups after treatment.Results The levels of TC[(4.23 ± 0.79)mmol/L vs.( 5.32 ±1.23)mmol/L],TG[(1.53±0.35) mmol/L vs.(5.32± 1.23) mmol/L],LDL-C [(3.19 ± 0.59)mmol/L vs.(4.07±0.79)mmo1/L]were decreased,while HDL-C [(1.53±0.95)mmol/L vs.(1.32±0.83)mmol/L]were increased in observation group after treatment as compared to control group (all P ＜0.05).After carotid artery ultrasonography,the LN[( 1.61± 0.76) scores vs.( 2.24 ± 0.89) scores ] and IMT [(0.76 ± 0.22)mm vs.(0.98 ± 0.28)mm] levels were lower in observation group after treatment than in control group (P＜0.05).Conclusions Amlodipine/atorvastatin combination can reduce blood lipids and alleviate atherosclerosis.It is suitable for elderly patients with hypertension and hyperlipidemia.

The value of serum cystatin C and urinary microalbumin in the diagnosis of early renal function injury in patients with essential hypertension / 中国医师进修杂志

ObjectiveTo investigate the clinical value of serum cystatin C(CysC) and urinary microalbumin(MA) in the diagnosis of early renal function injury in patients with essential hypertension.MethodsOne hundred and twenty patients with essential hypertension(hypertension group) were divided into three groups by the results of blood pressure:grade 1 with 48 cases,grade 2 with 47 cases,grade 3 with 25 cases.Thirty healthy subjects were selected as control group.Serum CysC,urinary MA and serum creatinine (Cr) were detected in all subjects.ResultsThe serum CysC and urinary MA in grade 1,2 and 3 hypertension group [(1.57 ±0.48),(2.12 ±0.72),(2.91 ± 1.09) mg/L and(18.12 ±5.43),(29.01 ±8.07),(46.06 ± 13.21 ) mg/L] were obviously higher than those in control group [ (0.71 ± 0.23 ),(9.35 ±5.17)mg/L](P＜ 0.05).The serum Cr had no significant difference between grade 1,2,3 hypertension group and control group (P ＞ 0.05 ).Serum CysC was positively correlated with urinary MA in hypertension group (r =0.613,P ＜ 0.05),serum CysC and urinary MA were both negatively correlated with estimated glomenlar filtration rate (eGFR)(r=-0.635,-0.563,P＜0.05).ConclusionsSerum CysC and urinary MA are sensitive indexes of early renal function injury in patients with hypertension.The combined determination of serum CysC and urinary MA can improve the detection rate of early renal function injury.

Effects of gastric bypass on non-obese type 2 diabetes mellitus / 中华内分泌外科杂志

Objective To observe therapeutical effects of gastric bypass on non-obese type 2 diabetes patients.Methods From June 2008 to April 2010,data of 47 patients with both gastric lesions and non-obese type 2 diabetes mellitus undergoing gastric bypass in the Institute of General Surgery were studied.The patients were divided into 3 groups according to the operation type:total stomach resection plus Roux-en-Y anastomosis ( n =20),partial stomach resection plus Roux-en-Y anastomosis(n =13)and Billroth Ⅱ gastrectomy(n =14).They were followed for 6 months after surgery.Level of body mass index (BMI),fasting blood glucose (FBG) and GLP-1 was measured before operation and on the 1 st week,2nd week,1 st month,3rd month,and 6th month after operation.The level of glycosylated hemoglobin was measured before operation and on the 3rd and 6th month after operation.The prognosis of the patients on the 6th month after surgery was evaluated.Results Compared with preoperative level,FBG level in all the 3 groups significantly decreased on the 1 st week after surgery and maintained a similar level during the follow-up period (P ＜ 0.01 ).GLP-1 level was elevated after operation (P ＜0.01 or P ＜ 0.05).On the 3rd and 6th month after operation,glycosylated hemoglobin level in all the 3 groups significantly decreased (P ＜ 0.01 or P ＜ 0.05 ).The change of the above parameters was greater in groups undergoing Roux-en-Y anastomosis than in Billroth Ⅱ group(P ＜ 0.05 ).The control rate of T2DM for Billroth Ⅱ,partial stomach resection plus Roux-en-Y anastomosis and total stomach resection plus Roux-en-Y anastomosis was 78.5％(11/14),100％ (13/13) and 100％ (20/20)respectively on the 6th month after surgery,indicating Roux-en-Y gastric bypass had better effect of blood glucose control than Billroth Ⅱ (P ＜ 0.05 ).Postoperative BMI decreased significantly in all groups (P ＜ 0.05) and there was no statistical difference between all the groups (P ＞ 0.05 ).Conclusions All groups of gastric bypass are effective in terms of glucose control.Roux-en-Y gastric bypass is more effective than Billroth Ⅱ on diabetes control and its therapeutic effect is independent of weight loss.
