ABSTRACT

Aim To explore the mechanism of hydroxy-a-sanshool in the treatment of diabetic cardiomyopathy ( DCM) based on label-free quantitative proteomics detection technique. Methods DCM model was established by high fat diet and intraperitoneal injection of streptozotocin ( STZ) . They were divided into control group ( CON group ) , diabetic cardiomyopathy group (DCM group) and hydroxy-a-sanshool treatment group ( DCM + SAN group) . The cardiac function of mice was evaluated by echocardiography, the myocardial morphology was observed by pathology staining, the protective mechanism of hydroxy-a-sanshool on diabetic cardiomyopathy was speculated by proteomic technique , and the expression level of cAMP/PKA signaling pathway and key proteins were verified by Western blotting. Results Cardiac ultrasound and pathology staining showed that hydroxy-a-sanshool had protective effect on the heart of DCM mice. Label-free quantitative proteomic analysis was carried out between DCM + SAN group and DCM group, and 160 differential pro-teins were identified by proteomics, in which 127 proteins were up-regulated and 33 proteins were down regulated ; GO secondary functional annotations showed the biological process, molecular function and cellular component; KEGG enrichment analysis showed that cAMP signaling pathway was the most abundant; protein interaction network showed that PKA as the central node interacted with many proteins in the cAMP signaling pathway. Western blot showed that the relative expression of с AMP, PKA protein in DCM group was significantly lower than that in CON group ( P < 0. 05 ) , while the relative expression of cAMP, PKA protein in DCM + SAN group was significantly higher than that in DCM group ( P < 0. 05 ) . Conclusions Hydroxy-a-sanshool has protective effect on heart function of mice with diabetes, which plays a role through cAMP signaling pathway.

ABSTRACT

As a single-center retrospective study, we analyzed the results of rotavirus and human adenovirus antigens in stool samples with colloidal gold immunochromatography method in children with acute gastroenteritis under the age of five who were treated in our hospital from 2019 to 2022. After excluding nonconforming cases and duplicate cases, 2 896 cases were included, of which 559 cases were detected with at least one viral antigen. According to the test results, they were divided into RV positive group, HAdV positive group and RV & HAdV double positive group. The gender, age, seasonal distribution, clinical symptoms and related laboratory tests were compared and analyzed with χ2 test, analysis of variance and nonparametric test. Among the single samples from 2 896 children, the positive rate of RV antigen was 6.21% (180/2 896), the positive rate of HAdV antigen was 10.91% (316/2 896), and the double positive rate of RV & HAdV was 2.18% (63/2 896). The positive rate of HAdV antigen in 2021 was 16.11%, a significant increase compared with 6.20% in 2020. RV infection has obvious seasonality, and spring and winter are the seasons with high incidence of infection (χ2=74.018, P<0.001), while HAdV infection has no obvious seasonality (χ2=2.110, P=0.550), showing sporadic infection throughout the year. The proportions of fever and vomiting symptoms in children with RV infection were significantly higher than those in the HAdV infection group (χ2=40.401, P<0.001; χ2=32.593, P<0.001), but the positive rate of white blood cells in the stool was significantly lower than that in the HAdV infection group (χ2=13.741,P<0.01). In summary, paying attention to the epidemiological changes of RV and HAdV is of great significance for clinical diagnosis and treatment and disease prevention and control.

ABSTRACT

Objective:To investigate the association of monocyte to lymphocyte ratio (MLR) with all-cause mortality and cardiovascular disease (CVD) mortality in patients with continuous ambulatory peritoneal dialysis (CAPD).Methods:It was a retrospective cohort study. The clinical data of 495 incident CAPD patients in the First Affiliated Hospital of Zhengzhou University from January 1, 2013 to December 31, 2019 were retrospectively analyzed. The optimal cut-off value of baseline MLR was determined by the receiver operating characteristic (ROC) curve for predicting all-cause death in the first year of CAPD, and then the patients were divided into high MLR group and low MLR group. The differences of clinical data and laboratory tests were compared between the two groups. The endpoint events were death (all-cause death and CVD death), conversion to hemodialysis, conversion to kidney transplantation, or follow-up until March 31, 2020. The survival curve was drawn by the Kaplan-Meier method, and the Log-rank test was used to compare the survival difference between the two groups. A Cox regression model was established to analyze the relevant factors of all-cause mortality and CVD mortality in CAPD patients.Results:The study included 495 patients, with age of (43.79±12.16) years and 308 (62.22%) males. The median age of dialysis was 17(10, 30) months. By the end of follow-up, 61(12.32%) of 495 patients had died, 51(10.51%) had been converted to hemodialysis, and 28(5.66%) had been converted to kidney transplantation. Of the 61 patients who died, 36(59.02%) died of cardiovascular events. ROC curve analysis results showed that the optimal cut-off value was 38.24%, so there were 246 cases in the high MLR group (MLR>38.24%) and 249 cases in the low MLR group (MLR≤38.24%). The all-cause mortality rates were 6.83% in the low MLR group and 17.89% in the high MLR group, and the CVD mortality rates were 3.21% in the low MLR group and 11.38% in the high MLR group, respectively. The Kaplan-Meier survival curve showed that the survival rate of the low MLR group was significantly higher than that of the high MLR group (all-cause mortality, Log-rank χ2=18.369, P<0.001; CVD mortality, Log-rank χ2=16.142, P<0.001). Using all-cause death as the end event, the 1-year, 3-year and 5-year cumulative survival rates were 99.5%, 89.4% and 79.9%, respectively, with a median survival time of 64 months in the low MLR group. The 1-year, 3-year and 5-year cumulative survival rates were 95.0%, 68.3% and 49.6%, respectively, with a median survival time of 54 months in the high MLR group. Using CVD death as the end event, the 1-year, 3-year and 5-year cumulative survival rates were 99.5%, 95.2% and 91.2%, respectively, with a median survival time of 69 months in the low MLR group. The 1-year, 3-year, and 5-year cumulative survival rates were 97.8%, 78.6%, and 60.8%, respectively, with a median survival time of 60 months in the high MLR group. Multivariate Cox regression analysis showed that MLR was independently associated with all-cause mortality ( HR=2.744, 95% CI 1.484-5.075, P=0.001) and CVD death ( HR=3.249, 95% CI 1.418- 7.443, P=0.005) in CAPD patients. According to the competing risk model analysis, MLR was still independently associated with all-cause mortality and CVD mortality in CAPD patients. Conclusion:MLR is associated with all-cause mortality and CVD mortality in CAPD patients, and can be used as a valuable indicator for judging the prognosis of CAPD patients.

ABSTRACT

Objective: To explore the influencing factors of pregnancy-induced hypertensive disorders in pregnancy (HDP) with organ or system impairment in pregnant women, and to analyze and compare the differences of HDP subtypes in different regions of China. Methods: A total of 27 680 pregnant women with HDP with complete data from 161 hospitals in 24 provinces, autonomous regions and municipalities were retrospectively collected from January 1, 2018 to December 31, 2018. According to their clinical manifestations, they were divided into hypertension group [a total of 10 308 cases, including 8 250 cases of gestational hypertension (GH), 2 058 cases of chronic hypertension during pregnancy] and hypertension with organ or system impairment group [17 372 cases, including 14 590 cases of pre-eclampsia (PE), 137 cases of eclampsia, 2 645 cases of chronic hypertension with PE]. The subtype distribution of HDP in East China (6 136 cases), North China (4 821 cases), Central China (3 502 cases), South China (8 371 cases), Northeast China (1 456 cases), Southwest China (2 158 cases) and Northwest China (1 236 cases) were analyzed. By comparing the differences of HDP subtypes and related risk factors in different regions, regional analysis of the risk factors of HDP pregnant women with organ or system impairment was conducted. Results: (1) The proportions of HDP pregnant women with organ or system impairment in Northeast China (79.05%, 1 151/1 456), Central China (68.42%, 2 396/3 502) and Northwest China (69.34%, 857/1 236) were higher than the national average (62.76%, 17 372/27 680); the proportions in North China (59.18%, 2 853/4 821), East China (60.85%, 3 734/6 136) and South China (59.56%, 4 986/8 371) were lower than the national average, and the differences were statistically significant (all P<0.05). (2) Univariate analysis showed that the proportions of primiparas, non-Han, non-urban household registration, irregular prenatal examination and PE history in the hypertension with organ or system impairment group were higher than those in the hypertension group, and the differences were statistically significant (all P<0.05). Multivariate logistic regression analysis showed that primiparas, non-Han, non-urban household registration, irregular prenatal examination and PE history were independent risk factors for HDP pregnant women with organ or system impairment (all P<0.05). (3) Primipara: the rates of primipara in Northeast China, North China and Southwest China were higher than the national average level, while those in South China, Central China and Northwest China were lower than the national average level. Non-Han nationality: the rates of non-Han nationality in Northeast China, North China and Northwest China were higher than the national average, while those in East China, South China and Central China were lower than the national average. Non-urban household registration: the rates of non-urban household registration in Northeast China, North China, and Southwest China were lower than the national average, while those in East China, Central China were higher than the national average. Irregular prenatal examination: the rates of irregular prenatal examination in North China, South China and Southwest regions were lower than the national average level, while those in Northeast China, Central China and Northwest China were higher than the national average level. History of PE: the incidence rates of PE in Northeast China, North China, South China and Southwest China were lower than the national average level, while those in Central China and Northwest China were higher than the national average level. Conclusions: Primiparas, non-Han, non-urban household registration, irregular prenatal examination, and PE history are risk factors for HDP pregnant women with organ or system impairment. Patients in Northeast, Central and Northwest China have more risk factors, and are more likely to be accompanied by organ or system function damage. It is important to strengthen the management of pregnant women and reduce the occurrence of HDP.

ABSTRACT

Objective:To investigate the clinical efficacy and safety of transurethral flexible ureteroscopy combined with single channel minimally invasive percutaneous nephroscopy in the treatment of complex renal calculi.Methods:A total of 72 patients with complex renal calculi admitted to Beijing Friendship Hospital, Capital Medical University from November 2019 to April 2022 were prospective selected, which were randomly divided into study group and control group by the random number table method, with 36 cases in each group. The control group underwent single channel minimally invasive percutaneous nephrolithotomy, while the study group underwent transurethral flexible ureteroscopy combined with single channel minimally invasive percutaneous nephrolithotomy. The perioperative indexes (operation time, postoperative hospital stay, intraoperative blood loss), stone removal effect, renal function indicators [blood urea nitrogen (BUN), serum creatinine (SCr)] and complication rate were compared between the two groups. Measurement data were expressed as mean ± standard deviation ( ± s), and t-test was used for inter-group comparison. The Chi-square test or Fisher exact probability method were used to compare the count data of two groups. Results:The operation time [(101.05±11.34) min vs (107.84±10.28) min] and postoperative hospital stay [(8.54±3.15) d vs (12.36±4.08) d] in the study group were significantly shorter than those in the control group, and the difference were statistically significant ( P<0.05). The amount of intraoperative bleeding was close to that in the control group, but the difference was not statistically significant ( P>0.05). The primary stone clearance rate and summary stone clearance rate in the study group were 91.67% (33/36) and 100.0% (36/36), respectively, which were significantly higher than 69.44% (25/36) and 83.33% (30/36) in the control group, and the differences were statistically significant ( P<0.05). The postoperative BUN and SCr levels in the study group were (5.24±0.31) mmol/L and (90.65±25.57) μmol/L, respectively, the control group was (7.69±0.78) mmol/L and (131.96±37.80) μmol/L, respectively. BUN and SCr levels in the study group were significantly lower than those in the control group, and the differences were statistically significant ( P<0.05). The total incidence of postoperative complications in the study group was significantly lower than that in the control group (5.56% vs 16.67%), and the difference was statistically significant ( P<0.05). Conclusion:Transurethral flexible ureteroscopy combined with single channel minimally invasive percutaneous nephroscopy is an ideal method for the treatment of complex renal calculi, which has good removal effect, less complications and helps to improve renal function.

ABSTRACT

Objective:To compare the specific mechanism and effects between christina loosestrife and snowbellleaf tickclover herb on kidney calcium oxalate calculi in rats.Methods:A total of 54 SPF grade SD male rats were fed adaptically for 1 week to 180-200 g, the models of rats with kidney calcium oxalate calculi were established by intragastric administration with glycol, and divided into nine groups according to random number table method and controlled, which were healthy control group (group A), positive control group (model group, group B), low, medium and high doses of christina loosestrife groups (C1, C2, C3, 3 groups), low, medium and high doses of snowbellleaf tickclover herb groups (D1, D2, D3, 3 groups), therapeutic control group (potassium sodium hydrogen citrate group, group E), 6 rats in each group. After 4 weeks, samples were collected to determine the urine and serum biochemical indexes of each group, and Von Kossa staining was used to detect kidney calcium oxalate crystals. Calcium oxalate crystal deposition in kidney tissues of rats was observed under polarization microscope, and the difference of efficacy between the two drug effects was determined by the percentage of positive area in photos and the urine and serum biochemical indexes. The measurement data were expressed as mean ± standard deviation ( ± s), one-way analysis of variance was used for comparison between groups, and SNK- q test was used for comparison between two groups. Kruskal-Wallis test was used to compare crystal formation between groups. Results:Compared with the positive control group and christina loosestrife groups, high dose of snowbellleaf tickclover herb could significantly reduce serum creatinine level ( P<0.01), the mean serum creatinine of rats with christina loosestrife was (86.70±11.49) μmol/L, that of rats with snowbellleaf tickclover herb was (70.72±9.08) μmol/L, the difference was statistically significant ( P<0.01). High dose of christina loosestrife and snowbellleaf tickclover herb could significantly increase urinary magnesium and decrease serum urea levels, and there was no statistical significance between them ( P>0.05). Compared with the positive control group, high dose of christina loosestrife ( P<0.000 1) and snowbellleaf tickclover herb ( P<0.000 1) could both inhibit the formation of calcium oxalate crystals and protect the kidney of rats, and there was no statistical significance between the two effects ( P>0.05). The levels of urine pH value could not be increased, while the levels of urinary calcium urinary oxalic acid and 24 h urine volume, serum calcium, serum phosphorus, serum magnesium, blood uric acid and content of kidney oxalate could not be decreased significantly after using these two drugs. Conclusion:Snowbellleaf tickclover herb is better than christina loosestrife in preventing recurrence of kidney calcium oxalate calculi and protecting renal function.

ABSTRACT

The fenrou zhijian is defined as potential gap between different layers in the three-dimensional network structure formed by the twelve meridian tendons. Various pathological changes of the meridian tendons lead to the adhesion and closure of fenrou zhijian, causing abnormal mechanical conduction of the meridian tendon system, which in turn leads to painful bi syndrome of meridian tendons. As such, restarting the fenrou zhijian is the key to acupuncture treatment for painful bi syndrome of meridian tendons. Under the guidance of musculoskeletal ultrasound, the level and the angle of needle insertion of acupuncture at fenrou zhijian could be accurately controlled, the efficacy of acupuncture is improved.

ABSTRACT

Objective:To investigate clinical features of congenital triangular alopecia.Methods:Clinical data were collected from 10 children with congenital triangular alopecia, who were diagnosed and treated in Xiamen Children′s Hospital from August 2020 to June 2021, and their clinical and dermoscopic features were analyzed.Results:All the 10 patients were males, aged from 2 months to 6 years and 4 months. Hair loss occurred at birth or within 1 month after birth in 6 children, and occurred between the age of 4 months and 6 years in 4. The alopecic area was located in the left frontotemporal region in 5 patients, in the right frontotemporal region in 3, and in the vertex region in 2. In all the patients, thin vellus hair could be seen in the alopecic areas, and the hair pull test was negative, while in 1 patient showed some normal terminal hair scattered in the alopecic area. Dermoscopy showed a lot of vellus hair surrounded by normal terminal hair in the alopecic area with a clear boundary, and no yellow or black dots, or 'exclamation mark’ hair was observed. Seven patients had visited department of dermatology due to hair loss, of whom 5 were diagnosed with alopecia areata, and 2 with sebaceous nevus.Conclusions:Congenital triangular alopecia is common in children, and mostly occurs in the left frontotemporal region. It is characterized by the replacement of normal terminal hair by thin vellus hair in the alopecic area. Dermoscopy is helpful in its diagnosis and differential diagnosis.

ABSTRACT

Objective:To investigate the safety and efficacy of individualized transperineal prostate biopsy based on the segmentation of PI-RADS v2 for mpMRI.Method:The clinical data of patients undergoing prostate biopsy in Beijing Friendship Hospital from December 2018 to November 2021 were analyzed retrospectively . A total of 228 patients with a median age of 65(49-83)years underwent biopsy. There were 102(44.7%) with tPSA <10 ng / ml, 108(47.4%) with tPSA 10-20 ng /ml, and 18(7.9%) with tPSA >20 ng /ml, with the median tPSA of 9.87(4.1-89.0)ng /ml. There were 42(18.4%) cases without MRI results, and 32(14.0%)cases with PI-RADS score of 1-2, 47(20.6%)cases of PI-RADS 3, 66(28.9%)cases of PI-RADS 4 and 41(18.1%)cases of PI-RADS 5, respectively.Transrectal ultrasound-guided transperineal prostate targeted biopsy (TB) and systematic biopsy (SB) were performed under local anesthesia or intravenous anesthesia. SB was performed for those without MRI and PI-RADS score of 1-2 (SB group), and TB and SB were performed for those with PI-RADS score of 3-5 (TB+ SB group). Prostate image under ultrasound was cognitively fused according to PI-RADS v2. One needle per area was distributed in 10 areas of each layer(the transition zone anterior and posterior sectors, the peripheral zone anterior, lateral, and medial sectors or central zone in left and right lobe). For those whose prostate length was less than 3cm, 10 needles were punctured, and two needles were added to each lateral lobe of the apex with a total of 14 needles. For those whose prostate length was from 3 to 6 cm, selected two layers with a total of 20 needles. For those with a length greater than 6cm, selected three layers with a total of 30 needles. If there was a suspicious lesion with PI-RADS score of 3-5, two needles were targeted for each lesion.The detection rate and complication rate of prostate cancer and clinically significant prostate cancer (csPCa) in the overall samples were observed, and the difference of the detection rate of prostate cancer and csPCa between the two groups was compared.Results:Of the 228 cases, there were 46 cases undergoing biopsy of one layer, 148 cases of two layers, and 34 cases of three layers, detecting 131 prostate cancer (PCa) diagnosed by pathology, with a detection rate of 57.5%, including 40 cases (17.5%)of clinically insignificant PCa and 91 cases(39.9%)of csPCa. The detection rate of PCa in TB+ SB group was 61.0%(94/154), which was higher than that in SB group, but there was no significant difference ( P=0.114). However, the detection rate of csPCa in TB + SB group was higher than that in SB group, which was 46.8%(72/154)vs. 25.6%(19/74), respectively ( P=0.002). In the combined TB and SB group (TB + SB group), the detection rate of csPCa by TB was 44.8% (69/154), which was higher than that of 33.8%(52/154)by SB( P=0.047). In the TB+ SB group, 7(4.5%) PCa were missed by SB, which was less than 18 cases (11.7%) missed by TB( P=0.022), but csPCa were missed by SB more than that missed by TB( P<0.001). There were 37 cases suffered from complications, with Clavien Dindo classification grade 1 of 29 cases (12.7%), grade 2 of 7 cases (3.1%), and grade 3 of 1 case(0.4%). Conclusions:Individualized transperineal prostate biopsy based on the segmentation of PI-RADS v2 for mpMRI is safe and reliable. Target biopsy by cognitive fusion can improve the detection rate of significant PCa. Systematic biopsy is also an important and essential supplement, which can detect prostate cancer missed by TB. Combined TB and SB are the best choice.

ABSTRACT

Objective: The survival rate of gastric cancer cases in the whole population of Qidong City of Jiangsu Province from 1972 to 2016 was analyzed to provide a data basis for prevention and control of gastric cancer. Methods: The observed survival rate (OSR) was calculated by the life table method, the relative survival rate (RSR) was calculated by SURV 3.01 software, and the trend test was performed by Hakulinen's likelihood ratio test. Age-standardized relative survival rate (ARSR) was calculated using the International Cancer Survival Standard (ICSS). The Joinpoint regression model was used to calculate the average annual percentage change (AAPC) of survival rate, and the trend analysis of the overall survival rate of gastric cancer and the survival rates of different sexes and ages was conducted. The ARIMA model was used to predict the survival rate. Results: From 1972 to 2016, there were 18 067 new cases of gastric cancer in Qidong City. The OSRs at 1, 5, and 10 years were 37.12%, 17.16%, and 12.86%, respectively, and the RSRs at 1, 5, and 10 years were 38.83%, 21.73%, and 21.20%. Dividing 1972-2016 into 9 periods at 5-year intervals, compared with 1972-1976, the 5-year RSR in 2012-2016 increased from 12.53% to 36.26%, and the RSR in the 9 periods increased with statistical significance (χ(2)=747.19, P<0.001). Both OSR and RSR were slightly higher in men than in women, and decreased with age. The AAPC results showed that the AAPC of the 5-year RSR of gastric cancer in Qidong was 2.88%, 2.75% in males and 3.05% in females, and the upward trend was statistically significant (P<0.001). From 1972 to 2016, the 5-year RSR of gastric cancer in all age groups showed an upward trend. Except for the 35-44-year-old group (AAPC=1.07%, t=2.16, P=0.067), the age groups had statistical significance ( AAPC=2.59% in the 45-54-year-old group, AAPC=3.19% in the AAPCs of other 55-64-year-old group, AAPC=3.99% in the 65-74-year-old group, and AAPC=2.97% in the 75-year-old group, all P<0.05). The prediction results of the ARIMA model showed that in 2026, the 5-year OSR of gastric cancer in Qidong will increase to 39.82%, and the 5-year RSR will increase to 49.23%. Conclusion: The overall survival rate of registered gastric cancer cases in Qidong has been greatly improved, but there is still large room for improvement. More attention should be paid to the prevention and treatment of gastric cancer.

ABSTRACT

Objective To evaluate the efficacy of ultrasound and computed tomography (CT) in diagnosing cervical lymph node metastasis (CLNM) of papillary thyroid carcinoma (PTC). Methods The patients with PTC treated by surgery in the Chinese PLA General Hospital from January 2016 to January 2021 were selected for analysis.All the patients underwent preoperative ultrasound and CT examinations,the diagnostic values of which for CLNM were retrospectively analyzed. Results A total of 322 PTC patients were enrolled in this study,including 242 with CLNM and 80 with non-CLNM.The CLNM group and non-CLNM group had significant differences in age,tumor size,and maximum size of lateral CLNM (χ2=20.34,27.34,and 4.30,respectively,all P<0.001).For the central compartment,lateral compartment,and overall compartment,ultrasound diagnosis showed higher sensitivity (χ 2=82.26,P<0.001;χ2=114.01,P<0.001;χ2=82.26,P<0.001) and accuracy (χ2=20.27,P<0.001;χ2=15.56,P<0.001;χ2=44.00,P<0.001) than CT,and had no significant differences from ultrasound combined with CT (all P>0.05).However,ultrasound diagnosis had lower specificity than CT (χ2=17.01,P<0.001;χ2=21.29,P<0.001) in the central compartment and lateral compartment.Receiver operating characteristic curve analysis showed that in the central compartment,lateral compartment,and overall compartment,ultrasound diagnosis had larger AUC than CT (Z=2.99,P=0.003;Z=3.86,P<0.001;Z=4.47,P<0.001) and had no significant difference from ultrasound combined with CT (Z=1.87,P=0.062;Z=1.68,P=0.093;Z=1.61,P=0.107). Conclusions Ultrasound and CT have their own advantages in the diagnosis of central and lateral CLNM.In general,ultrasound has better performance than CT in the diagnosis of CLNM.

ABSTRACT

Objective:To investigate the efficacy of deep hyperthermia combined with recombinant human vascular endothelial inhibitor injection and AP (pemetrexed + cisplatin) regimen in the treatment of advanced non-small cell lung cancer (NSCLC) and its effects on serum tumor marker levels and immune function of patients.Methods:In this prospective randomized controlled study, 106 patients with advanced NSCLC who were admitted to the Seventh People's Hospital of Hebei Province from January 2016 to January 2022 were included, and were divided into two groups according to the random number table method, with 53 cases in each group. The control group was treated with recombinant human vascular endothelial inhibitor injection combined with AP regimen. The observation group was given recombinant human vascular endothelial inhibitor injection combined with AP regimen and deep hyperthermia. After 4 consecutive cycles of treatment, the short-term efficacy of the two groups was observed. Chemiluminescence assay was used to detect the serum levels of carcinoembryonic antigen (CEA), carbohydrate antigen 125 (CA125) and cytokeratin fragment 19 CYFR21-1 before and after treatment. T lymphocyte subsets in peripheral blood were detected by flow cytometry. The occurrence of adverse reactions was compared between the two groups.Results:The objective response rates in observation group and control group were 58.49% (31/53) and 37.74% (20/53), the disease control rates in observation group and control group were 92.45% (49/53) and 75.47% (40/53), the observation group was higher than the control group ( χ2 = 4.53, P = 0.033; χ2 = 5.62, P = 0.018). The differences in serum carcinoembryonic antigen (CEA), glycoantigen 125 (CA125) and CYFR21-1 levels between the two groups before treatment were not statistically significant (all P > 0.05), they were lower in both groups after treatment than before treatment (all P < 0.05), and they were lower in the observation group after treatment than in the control group after treatment (all P < 0.05). The differences in peripheral blood CD3 +, CD4 + and CD8 + T-cell levels and CD4 + to CD8 + T-cell ratio (CD4 +/CD8 +) between the two groups before treatment and in the observation group before and after treatment were not statistically significant (all P > 0.05). Peripheral blood CD3 + and CD4 + T-cell levels and CD4 +/CD8 + in the control group after treatment were lower than before treatment (all P < 0.05), and the peripheral blood CD8 + T-cell level was higher than before treatment ( P < 0.05). CD3 + and CD4 + cell levels and CD4 +/CD8 + in the observation group after treatment were higher than those in the control group after treatment, CD8 + T-cell level was lower than the control group after treatment, and the differences were statistically significant (all P < 0.001). There were different degree of gastrointestinal reactions, bone marrow suppression, liver and kidney damage and cardiotoxicity in both groups during treatment, but the differences in the incidence of each adverse reaction between the two groups were not statistically significant (all P > 0.05). Conclusions:Deep hyperthermia combined with recombinant human vascular endothelial inhibitor injection and AP regimen in the treatment of advanced NSCLC can effectively reduce the serum tumor marker levels, improve the immunosuppression status of the body and enhance the recent efficacy, and the overall adverse reactions are controllable and well tolerated by patients.

ABSTRACT

Aim To investigate the protective effect of naringin ( NA) on diabetic cardiomyopathy by activating the large conduction Ca2+ activated K4 channels (Maxi K ).Methods SD rats were fed with high-fat diet combined with intraperitoneal injection of strepto- zotocin (STZ) to establish a diabetic rat model.Then the rats were randomly divided into model group ( DCM) , naringin group ( NA) and naringin + Maxi K-specific inhibitor group ( NA + PAX) , with 8 rats in each group.Hats in treatment group received administration for 12 weeks and blood glucose was monitored regularly during experiments.The changes of cardiac function, morphology and fibrosis were detected after the treatment.The changes of cx and (3 subunits of Maxi K in heart were detected.Results Cardiac ultrasound results showed that NA could partially restore the cardiac function of rats.However, the cardiac protec tive function of NA was significantly reduced in diabetic rats after Maxi K was specifically blocked.Fibrosis analysis showed that the expression of collagen and fi- bronectin in rats could be decreased after NA treatment, which could be partially reversed by PAX.Western blot results showed that the expression of Maxi K a and p-subunit decreased in DCM group, but there was no significant change after NA treatment.Conclusions NA has a cardioprotective effect on diabetic rats by promoting the opening of the Maxi K channel on the membrane surface rather than increasing its expression.

ABSTRACT

Objective:To investigate the correlation between serum procalcitonin (PCT) level and intracranial atherosclerotic burden (ICASB) in patients with ischemic stroke.Methods:From January 2019 to December 2020, consecutive patients with acute ischemic stroke admitted to the Department of Neurology, Jiangsu Provincial Second Chinese Medicine Hospital were enrolled. Chemiluminescence immunoassay was used to detect serum PCT levels, and ICASB was evaluated based on the results of cranial magnetic resonance angiography. Univariate analysis was used to determine the baseline data among the different ICASB score groups. Then the independent correlation between serum PCT level and ICASB was determined by the ordinal logistic regression analysis. At the same time, the correlation between serum PCT level and ICASB was determined by the linear regression analysis. Results:A total of 291 patients with acute ischemic stroke were enrolled, including 161 male (55.3%), aged 64.5±8.4 years; median serum PCT level was 0.053 μg/L. According to the ICASB score, the patients were divided into 0 group ( n=155, 53.3%), 1-3 group ( n=95, 32.6%) and >3 group ( n=41, 14.1%). Univariate analysis showed that the age, serum homocysteine and PCT level, as well as the proportion of diabetes were significantly higher in the higher ICASB score group, while the proportion of the patients with atrial fibrillation was significantly lower (all P<0.05). Ordinal multivariable logistic regression analysis showed that higher serum PCT level was an independent factor for higher ICASB score (the 4 th quartile vs. the 1 st quartile: odds ratio, 2.015, 95% confidence interval 1.052-3.927; P=0.043). Multiple linear regression analysis showed that the serum PCT level was positively correlated with the ICASB score ( r=0.253, P=0.001). Conclusion:The serum PCT level is correlated with ICASB.
