ABSTRACT

Objective:To explore the clinical efficacy and safety of the camrelizumab combined with apatinib and chemotherapy as second-line or later therapy in human epidermal growth factor receptor-2 (HER-2) negative advanced gastric cancer.Methods:A total of 66 patients with HER-2 negative advanced gastric cancer and first-line treatment failure in Shandong Cancer Hospital Affiliated to Shandong First Medical University from March 2018 to September 2021 were selected. They were divided into study group ( n=22) and control group ( n=44) according to the different treatment regimens. The patients in the study group were treated with camrelizumab combined with apatinib and chemotherapy, and the patients in the control group were treated with chemotherapy alone. The short-term efficacy, progression-free survival (PFS) , overall survival (OS) and the occurrence of adverse reactions were compared, and Cox regression analysis was used to analyze the influencing factors of prognosis. Results:After at least 2-4 cycles of treatment, the ORR in the study group and the control group were 9.1% (2/22) and 0 (0/44) respectively, with no statistically significant difference ( P=0.108) . DCR in the two groups were 77.3% (17/22) and 45.5% (20/44) respectively, with a statistically significant difference ( χ2=6.03, P=0.014) . The study group didn’t reach median OS and the median OS in the control group was 11.7 months, with no statistically significant difference ( χ2=1.59, P=0.207) . The study group didn’t reach median PFS and the median PFS in the control group was 3.2 months, with a statistically significant difference ( χ2=10.13, P=0.001) . Multivariate Cox regression analysis showed that treatment method was an independent influencing factor for PFS in patients with HER-2 negative advanced gastric cancer ( HR=0.33, 95% CI: 0.15-0.75, P=0.008) . In terms of adverse reactions, there was a statistically significant difference in the incidence of elevated alanine aminotransferase between the study group and the control group [31.8% (7/22) vs. 6.8% (3/44) , χ2=5.32, P=0.021]. There were no adverse-related deaths in both groups. Conclusion:Compared with chemotherapy alone, camrelizumab combined with apatinib and chemotherapy as a second-line or later therapy in HER-2 negative advanced gastric cancer can prolong PFS and improve DCR, but the incidence of elevated alanine aminotransferase increases significantly.

ABSTRACT

Objective:To investigate the clinicopathological characteristics of non-Hodgkin lymphoma (NHL) in Shandong province.Methods:The clinicopathological data of 2 886 NHL cases in Shandong Cancer Hospital from January 2002 to December 2017 were retrospectively analyzed, the clinicopathological characteristics of patients were summarized and compared with other regions in China and abroad.Results:The median age of all NHL cases was 52 years old (4-90 years old), and the ratio of male to female was 1.57∶1. The subtypes distribution analysis revealed that B-cell NHL (B-NHL) accounted for 66.7% (1 925 cases) of all cases and T-cell NHL (T-NHL) accounted for 27.3% (788 cases) of all cases. The common subtypes were diffuse large B-cell lymphoma (36.0%, 1 039/2 886), NK/T-cell lymphoma (8.8%, 254/2 886), follicular lymphoma (8.2%, 237/2 886) and peripheral T-cell lymphoma (7.4%, 214/2 886). Of all the cases, the nodal lymphomas accounted for 45.8% (1 322 cases) and the extra nodal lymphomas accounted for 54.2% (1 564 cases); there were 389 patients (13.5%) with stage Ⅰ, 678 patients (23.5%) with stage Ⅱ, 975 patients (33.8%) with stage Ⅲ, and 722 patients (25.0%) with stage Ⅳ. The distribution of NHL subtypes in Shandong province was consistent with the domestic multicenter study. However, T-NHL subtype ratio was significantly higher than the foreign studies.Conclusions:The overall incidence of NHL in Shandong province of China is dominated by middle-aged people, and the proportion of B-NHL is higher than that of T-NHL. The distribution of NHL subtypes in Shandong province of China are different from those in the European and American countries, but are roughly consistent with the domestic multicenter study.

ABSTRACT

Objective To investigate the clinical efficacy and mechanism of rosuvastatin combined with telmisartan in the treatment of persistent atrial fibrillation. Methods One hundred and twenty patients with persistent atrial fibrillation admitted to Cangzhou Central Hospital from February 2015 to February 2018 were enrolled and they were divided into study group and control group by random envelope method, with 60 patients in each group. The patients in study group were treated with rosuvastatin combined with telmisartan; and in control group they were treated with telmisartan, and after treatment for 6 weeks the clinical efficacy was observed. Resting heart rates were observed in two groups. The left atrial inner diameter, left atrium left and right diameter, left atrial sphericity index and left ventricular end diastolic volume, left ventricular end systolic volume, left ventricular posterior wall thickness of two groups were detected by ultrasond before and after treatment; the levels of serum tumor necrosis factor-α (TNF-α) and interleukin-6 (IL-6) were tested by enzyme linked immunosorbent assay (ELISA) in two groups before and after treatment; and the level of serum hypersensitive C-reactive protein (hs-CRP) was detected by immunoturbidimetry;the level of plasma N-terminal pro-brain natriuretic peptide (NT-proBNP) was tested by immunoluminometric assay. Results Resting heart rate was significantly decreased in study group after treatment compared with that before treatment (bpm: 76.37±7.25 vs. 89.76±8.79, P < 0.05), while in control group, the comparison of resting heart rate before and after treatment was of no statistical significant differences (bpm: 90.71±8.56 vs. 87.80±6.26, P > 0.05), resulting that the post-treatment resting heart rate of study group was significantly lower than that of control group (bpm:76.37±7.25 vs. 87.80±6.26, P < 0.05). After treatment, the left atrial inner diameter, left atrium left and right diameter, left atrial sphericity index and left ventricular end diastolic volume were increased compared with those before treatment in both groups; after treatment, above various index levels in study group were lower than those of control group [left atrial inner diameter (mm): 40.68±3.86 vs. 41.99±3.97, left atrium left and right diameter (mm): 41.07±2.85 vs. 42.69±2.90, left atrial sphericity index: 0.77±0.08 vs. 0.86±0.07, left ventricular end diastolic volume (mL): 107.48±32.90 vs. 118.98±35.75, all P < 0.05]. There were no statistical significant differences between the two groups in left ventricular end systolic volume and posterior wall thickness of left ventricle after treatment [study group: left ventricular end systolic volume (mL) was 38.59±12.37 vs. 39.81±12.03, posterior wall thickness of left ventricle (mm) was 11.34±2.39 vs. 12.80±3.27, control group: left ventricular end systolic volume (mL) was 39.90±11.54 vs. 40.65±11.50, posterior wall thickness of left ventricle (mm) was 11.90±2.57 vs. 12.99±3.16, all P > 0.05]. Besides, the serum levels of TNF-α, IL-6 and hs-CRP were obviously decreased in two groups after treatment (all P < 0.05), after treatment, above indexes in study group were significantly lower than those in control group [TNF-α (ng/L): 29.76±5.31 vs. 36.63±5.11, IL-6 (ng/L): 14.37±3.36 vs. 22.65±4.58, hs-CRP (mg/L): 13.68±2.75 vs. 20.63±2.69, all P < 0.05]. Plasma NT-proBNP was increased in control group after treatment compared with that before treatment (μg/L: 431.80±42.54 vs. 365.89±39.81, P < 0.05), whereas there was no significant difference in the study group between pre- and post-treatment (μg/L: 351.80±38.76 vs. 346.89±35.82, P > 0.05), resulting in post-treatment plasma NT-proBNP significantly lower in study group (P < 0.05). Conclusions Rosuvastatin combined with telmisartan can prevent left atrial remodeling in patients with persistent atrial fibrillation and delay the dysfunction of left ventricular pump. The therapeutic mechanism was related to the decrease in the levels of serum inflammatory factors in patients treated with such therapy.

ABSTRACT

Objective To observe the effects of recombinant human B-type natriuretic peptide (rhBNP) on cardiac function and heart rate variability (HRV) in patients with heart failure after acute myocardial infarction (AMI). Methods One hundred and twenty patients with heart failure after AMI admitted to the Department of Cardiology of Cangzhou Central Hospital of Hebei Province from January 2015 to January 2018 were enrolled. The patients were divided into a conventional treatment group and an rhBNP treatment group according to random number table method, with 60 cases in each group. The two groups were treated according to the AMI guidelines, the conventional treatment group received west medicine anti-myocardial ischemia and anti-heart failure treatment; the rhBNP treatment group received rhBNP on the basis of routine treatment; the first load dose was 2 μg/kg intravenous injection impact treatment, followed by maintaining dose 8.5 ng·kg-1·min-1 intravenous drip for 7 days. The changes of hypersensitivity C-reactive protein (hs-CRP), N-terminal B-type natriuretic peptide precursor (NT-proBNP), left ventricular ejection fraction (LVEF) and HRV index were observed before and after treatment in the two groups [HRV indexes including the changes of average normal RR interval standard deviation (SDNN), the average value of the normal RR interval standard deviation (SDANN), the root mean square (RMSSD) of the adjacent RR interval difference, and the percentage of adjacent RR interval difference > 50 ms (PNN50)]; the incidences of adverse reactions in the two groups were observed. Results After treatment, the levels of hs-CRP and NT-proBNP in the two groups were significantly lower than those before treatment (all P < 0.05). LVEF, SDNN, SDANN, RMSSD and PNN50 were higher than those before treatment, and the changes of the above indicators in the rhBNP treatment group were more significant than those in the conventional treatment group [hs-CRP (mg/L): 6.2±3.3 vs. 11.8±5.5, NT-proBNP (ng/L): 2.5±2.0 vs. 6.4±4.3, LVEF: 0.49±0.02 vs. 0.44±0.04, SDNN (ms): 93.3±18.1 vs. 79.1±16.0, SDANN (ms): 87.3±17.8 vs. 70.9±14.9, RMSSD: 30.3±11.0 vs. 23.8±10.4, PNN50: (15.9±7.3)% vs. (9.6±5.5)%, all P < 0.05]; No significant adverse reactions occurred during the treatment of the two groups. Conclusion rhBNP can significantly improve the heart function of patients with heart failure after AMI, reduce the levels of inflammatory response indicators and improve HRV;since its clinical efficacy is good, and its application safe, it is worthy to promote its clinical use.

ABSTRACT

Objective To explore the effects of smoking on medications and provide an accurate and reliable evidence for smoking patients. Methods The drug instructions were surveyed from Datong medical drug counselling software database, and then the effects of smoking on drugs were analyzed by the drug instructions combined with the literature reports. Results There were 48 drugs varieties which might interact with smoking in Chinese drug instructions filtered from Datong medical drug counselling software database,which was much less than the report surveyed based on the FDA drug instructions(188 drugs varieties),there were another 37 varieties that off the instructions,reported by literatures interacted with smoking.Analysis revealed that smoking effects on drugs mainly by means of changing the pharmacokinetics and reducing the efficacy through inducing the CYP1A2,increasing the morbidity of some diseases such as cardiovascular disease,and increasing the adverse drug reactions.It was found that dosages of 8 drugs varieties need to be adjusted in smokers which were mainly or partly metabolized by CYP1A2.They are hydrochloride erlotinib,theophylline,riociguat,insulin,warfarin,clozapine,olanzapine and chlorpromazine. Dosage of 9 drugs varieties may need to be increased in smokers. Conclusion For the purpose of rational drug use,dosage of a variety of drugs should be adjusted in smokers.

ABSTRACT

Objective To investigate the protection effect of dexmedetomidine against H2O2 injury in Human renal tubular epithelial cells(HK-2 cells). Methods HK-2 cells cultured in vitro were randomly divided into four groups(n = 24): control group, dexmedetomidine pretreatment group, H2O2 injury group, H2O2 injury +dexmedetomidine pretreatment group. Cell viabilities were measured by MTS assay, cell apoptosis were detected using flow cytometry, and expression of HIF-1α protein was quantified by western blot. HK-2 cells were divided into 8 groups by combining with three treatment factors such as PI3K inhibitor LY294002, dexmedetomidine and H2O2 injury. MTS assay was used to detect cell viability and western blot was used to quantify protein expression of HIF-1α,Bcl-2 and Bax after treatment in each group. Results Dexmedetomidine significantly increased the level of HIF-1α、 Bcl-2 in HK-2 cells after H2O2 injury, thus improved viabilities and reduced apotosis of cells. Moreover, effect on H2O2 injury cells of Dexmedetomidine was reversed by PI3K inhibitor LY294002. Conclusion Dexmedetomidine could protect against H2O2 injury by up-regulating HIF-1α expression through activating PI3K/Akt/mTOR signaling pathway in HK-2 cells.

ABSTRACT

Objective To evaluate the role of mammalian target of rapamycin (mTOR) signaling pathway in dexmedetomidine-induced reduction of renal ischemia-reperfusion (I/R) injury in rats and the relationship with hypoxia-inducible factor 1 (HIF-1α).Methods Seventy-two male Sprague-Dawley rats, aged 10-12 weeks, weighing 220-260 g, were randomly divided into 4 groups (n=18 each) using a random number table: sham operation group (group S), group I/R, dexmedetomidine group (group Dex) ,and rapamicyn + dexmedetomidine group (group Rpm+Dex).Renal I/R was produced by occlusion of bilateral renal pedicles for 35 min follow by reperfusion in anesthetized rats in I/R, Dex and Rpm+Dex groups.Bilateral renal pedicles were only exposed, and then the abdominal cavity was closed in group S.Dexdetomidine 50 μg/kg was injected intraperitoneally at 30 min before I/R in group Dex.In group Rpm+Dex, rapamicyn 1.5 mg/kg and dexdetomidine 50 μg/kg were injected intraperitoneally, and renal I/R model was established 30 min later.Immediately after onset of reperfusion, and at 4 and 24 h of reperfusion (T1-3) , blood samples were collected from the caudal vein for measurement of serum creatinine and blood urea nitrogen (BUN) concentrations.After blood sampling at T1-3, the rats were sacrificed, and the renal specimens were obtained for detection of HIF-1αt, erythropoietin (EPO) and mTOR expression by Western blot.Their kidneys were removed at T3, and cut into sections which were stained with haematoxylin and eosin and examined under microscope.Acute renal tubular necrosis was scored.The cell apoptosis in renal tissues was detected by TUNEL assay, and apoptosis index (AI) was calculated.Results Compared with group S,the concentrations of serum creatinine and BUN, expression of HIF-1α, EPO and mTOR at T2,3 , AI at T3 and acute renal tubular necrosis score were significantly increased in the other three groups (P< 0.05).Compared with group I/R, the concentrations of serum creatinine and BUN were significantly decreased, and the expression of HIF-1α, EPO and mTOR was up-regulated at T2,3 , and AI and acute renal tubular necrosis score were decreased in group Dex (P<0.05) , and no significant change was found in the parameters mentioned above in group Rpm + Dex (P > 0.05).Conclusion The mTOR signaling pathway is involved in dexmedetomidine-induced reduction of renal I/R injury, which may be related to dexmedetomidine-produced up-regulation of HIF-1α expression in renal tissues of rats.

ABSTRACT

Objective To evaluate the gene amplification and protein expression of HER-2 in gastric carcinoma with or without neuroendocrine differentiation (NED), and to explore the difference in HER-2 gene profile between these two neo?plasms. Methods Cases of gastric carcinoma with NED (n=70) and cases of gastric carcinoma without NED (n=150) were retrospectively reviewed. Gene amplification and protein expression of HER-2 genes in gastric carcinoma with or without NED were detected by combination of immunohistochemical method (IHC) and double color silver dye for in situ hybridiza?tion (DISH). Prognosis of gastric cancer patients with NED were predicted using Kaplan-Meiers survival analysis. Results Expression rates of HER-2 in gastric cancer with and without NED are 20.00%and 21.33%respectively. Amplification of HER-2 in gastric cancer with and without NED are 8.57%and 14.67%respectively. Gene amplification and protein expres?sion of HER-2 between gastric cancer with NED and without NED showed no statistical difference. Chromosome 17 multi-body positively correlated with gene HER-2 amplification in Gastric carcinoma with NED. Postoperative survival period in patients of gastric carcinoma with NED and HER-2 amplification was shorter than that in patients of gastric carcinoma with?out NED but with HER-2 amplification. Gastric carcinoma with or without NED, HER-2 gene amplification, lymph node me?tastasis and operation method obviously correlate with prognosis of gastric carcinoma patients (P<0.05). Conclusion The gastric cancer with NED is a special type of gastric cancer, there was no difference of gene amplification and protein expres?sion of HER-2 gene between gastric carcinoma with NED and without NED. Poor prognosis would be expected in gastric can?cer patients with NED and HER-2 amplification.

ABSTRACT

<p><b>OBJECTIVE</b>To study the impacts of electroacupuncture (EA) on memory impairment after cerebral infarction through the observation of hydrogen proton magnetic resonance spectroscopy (1H-MRS) of brain tissue metabolites in the patients of cerebral infarction.</p><p><b>METHODS</b>Sixty cases of memory impairment after cerebral infarction were randomized into an observation group and a control group, 30 cases in each one. The conventional rehabilitation training and medication were applied to all the patients. In the observation group, beside the basic treatment, EA was applied to bilateral Ezhongxian (MS 1), Dingzhongxian (MS 5), Dingniehouxiexian (MS 7), Hegu (LI 4), Taichong (LR 3), Zusanli (ST 36), Taixi (KI 3), Xuanzhong (GB 39) and Fengchi (GB 20). The treatment was given once a day, 5 times a week, for 8 weeks. The clinical memory scale was used for the score evaluation before and after treatment in all the patients. The magnetic resonance image (MRI) and 1H-MRS scanning were applied to the head. The ratio of N-acetyl aspartate (NAA) and creatine (Cr) and the ratio of choline (Cho) and Cr were determined in the foci of cerebral infarction.</p><p><b>RESULTS</b>Eight weeks later, the scores of clinical memory scale were all increased after treatment as compared with those before treatment in the two group (all P<0. 01). The ratio of NAA and Cr was increased as compared with that before treatment (P<0. 05); the ratio of Cho and Cr was reduced as compared with that before treatment (P<0. 05). The changes in the observation group were more obvious than those in the control group (all P<0. 05).</p><p><b>CONCLUSION</b>On the basis of the conventional medication and rehabilitation training, EA improves the metabolism of brain tissue and memory function of the patients. The efficacy of this therapy is better than that of medication combined with rehabilitation training.</p>

ABSTRACT

Objective To analyze the restricted usage of TCRβ V/J subfamily and CDR3 repertoire in patients with peripheral T-cell lymphoma unspecified (U-PTL).Methods The total RNA was respectively extracted from lymph node of U-PTL and reverse transcriptase,then multi-PCR was used to amplify the complete DNA sequence(CDS) of TCR β-chain.The recombinant plasmids were sequenced and sequence was analyzed by using online TCR resources.Results There were 9 TCR β chain CDS obtained from four patients.TCRβ-chain presented specific repertoire skewing in patients with U-PTL.There were restricted usage of BV2,BV4S2,BV14,BV29S1 of BV subfamily and BJ1S4,BJ2S3,BJ2S5,BJ2S7 of BJ subfanily.The clonal proliferation T cells had different CDR3 amino acid sequences.Conclusions There are restricted usage of TCR β V/J subfamily in patients with U-PTL.The sequences of CDR3 in different TCR clone proliferation are mostly different.

ABSTRACT

Objective:To develop a new method of manufacture of presurgical nasal stent by computer-aided design and manufactur-ing(CAD/CAM)technique for infants with cleft palate and nasal deformity.Methods:A neonate with unilateral lip and palate cleft and nasal deformity was recruited.The nose-lip area was scanned by a 3D human body scanner and transformed into 3D digital model by the reverse engineering software.The nasal data of the normal side was mirrored to cover the deformed side and processed by the re-verse engineering software,which became the original data of the presurgical nasal stent.Nasal stent was manufactured by rapid proto-typing machine.The stent was applied for the patient to correct the nasal deformity.Results:The original data of the nose-lip area were obtained via scanning within 0.1 second,and the 3D model was reconstructed by the reverse engineering software.The nasal stent made by CAD/CAMtechnique matched perfectly with the models and fitted well when tried on the patient's face.The appearance of the deformed nose was obviously improved by the nasal stent.Conclusion:CAD/CAMtechnologies can be used in the design and manu-facture of individual nasal stent for infants with cleft palate and nasal deformity.
