Objective: To observe the clinical efficacy of grain-sized moxibustion in treating chemotherapy-induced myelosuppression for non-small cell lung cancer (NSCLC) and its effect on quality of life (QOL). Methods: Eighty NSCLC patients admitted to the Inpatient Department of Zhejiang Cancer Hospital between September 2016 and March 2018 were recruited and divided into an observation group and a control group by random number method, with 40 cases in each group. The two groups both received chemotherapy with paclitaxel plus cisplatin (TP regimen). The control group received oral administration of leucogen tablets starting from the first day of chemotherapy, 20 mg each time, three times a day, for consecutive 14 d; the observation group was additionally given grain-sized moxibustion, once a day, five days per week at a two-day interval, until the fourteenth day. The myelosuppression severity was observed and compared between the two groups prior to chemotherapy, at the 3rd, 7th and 14th days of chemotherapy; the QOL in the two groups was evaluated before chemotherapy, at the 14th and 21st days of chemotherapy. Results: Regarding myelosuppression, the peripheral blood indicators increased significantly at the 3rd day of chemotherapy in both groups (P<0.05 or P<0.01); at the 7th and 14th days of chemotherapy, the peripheral blood indicators presented a decreasing tendency in the two groups, but the level in the observation group was still significantly higher than that before chemotherapy (P<0.01); at the 3rd, 7th and 14th days of chemotherapy, the peripheral blood indicators in the observation group were higher than those in the control group (P<0.05 or P<0.01); the occurrence rate of myelosuppression in the observation group was significantly lower than that in the control group (P<0.01). The QOL score in the observation group was markedly higher than that in the control group at the 14th and 21st days of chemotherapy (both P<0.05). Conclusion: Grain-sized moxibustion can effectively improve myelosuppression after chemotherapy for NSCLC, reducing its occurrence and enhancing the patient's QOL.

This study was aimed to construct the shRNA eukaryotic expression vectors of M2-pyruvate kinase gene (pkm2) and to investigate the effects of pkm2 gene interference on the drug resistance of acute promyelocytic leukemia (APL) cells in vitro. Three specific shRNAs of pkm2 gene were designed and cloned into PBSU6 vector containing a U6 promotor. The constructed plasmids were identified and proved by the restriction sequence analysis. Then the effect of pkm2-shRNA on the protein expression of endogenous PKM2 was detected in NB4R2 cells, a drug resistant cell line of APL by Western blot. The alteration of NB4R2 cell differentiation with the interference of pkm2 gene was also validated by nitroblue tetrazolium (NBT) reduction test. The results showed that three specific shRNA eukaryotic expression vectors targeting pkm2 were successfully constructed. The efficiency of pkm2 gene silence was proved at protein level. The interference of pkm2 gene could significantly enhance the cell differentiation in the drug resistant NB4R2 cell line. It is concluded that the DNA vector containing pkm2 targeting shRNA remarkably promotes the differentiation of NB4R2 cells, showing the prospects of developing the gene target drug.

OBJECTIVETo evaluate and compare the efficacy and safety of Nedaplatin (NDP)-based regimen and cisplatin (DDP)-based regimen for head and neck squamous cell carcinoma (HNSCC), non-small cell lung cancer (NSCLC), esophageal cancer and ovary epithelial cell carcinoma.

METHODSSingle agent group: NDP was administered at a dose of 100 mg/m(2) on D1, every 3 weeks for at least 2 cycles. Combination chemotherapy group: combined with 5-Fu, NVB, VDS + 5-Fu, PTX or CTX respectively, NDP 80 mg/m(2) on D1 or DDP 30 mg/m(2) on D1-3, every 3 weeks for at least 2 cycles was given.

RESULTSOf 237 patients in this trial, 37 were treated by single Nedaplatin, 139 by NDP-based regimen, 61 by DDP-based regimen in the control group. The response rate of single Nedaplatin chemotherapy for advanced NSCLC was 10.5% (2/19), for ovary carcinoma (1/3) and HNSCC (1/1). For NSCLC and ovary carcinoma patients who had failed in the previous DDP-based chemotherapy, the response rates by single NDP chemotherapy were still 9.1% and 33.3%. The response rate of NDP-based combination regimen for NSCLC, ovary carcinoma, HNSCC and esophageal cancer was 33.9% (21/62), 44.8% (13/29), 20.0% (3/15) and 18.2% (4/22), respectively, which was not statistically different from the rate of controlled group treated by DDP-based regimen. For chemonaive NSCLC, the effect of NDP-based combination regimen (35.7%) was significantly superior to the effect of DDP-based regimen (17.1%) (P = 0.045). The most common adverse events of nedaplatin were myelosuppression (leukopenia, thrombocytopenia, anemia), nausea and vomiting. The myelosuppression and renal toxicity of NDP-based regimen were similar to that of DDP-based regimen, but vomiting was milder than that of DDP-based regimen (54% vs. 75.4%), and grade I/II liver toxicity was more common in the NDP-based regimen than in DDP-based regimen (10.8% vs. 0).

CONCLUSIONNedaplatin is effective in the treatment for HNSCC, NSCLC and ovary carcinoma. Compared with the control group treated by DDP-based regimen, nedaplatin-based combination chemotherapy has similar effect on HNSCC, NSCLC, ovary carcinoma and esophageal cancer. Gastrointestinal reaction of nedaplatin is milder than that of cisplatin but the liver function during chemotherapy must be monitored closely.

Objective: To investigate the effects of femoral approach versus radial approach on the incidence of contrast-induced acute kidney injury (CI-AKI) in patients with coronary heart disease, who received twice contrast agents within a short interval. Methods: A total of 322 patients with coronary heart disease, who admitted to the General Hospital of Northern Theater Command from January 2010 to January 2015, were included in this retrospective analysis. All patients exposed to contrast agents twice within 30 days. The patients were divided into two groups according to the approach of interventional operation: radial artery group (n=235) and femoral artery group (n=87). Serum creatinine (SCr) values were detected at 48 and 72 hours post procedure. Endpoint events were CI-AKI, which was defined as SCr increased>0.5 mg/dl (44.2 μmol/L) or relative ratio ((postoperative SCr-preoperative SCr)/preoperative SCr×100%>25%) within 72 hours after contrast agent use after excluding other causes. Clinical characteristics and the incidence of CI-AKI were compared between the two groups, multivariate logistic regression analysis was used to detect the risk factors of postoperative CI-AKI in these patients. Results: The proportion of smoking, PCI history, STEMI patients and levels of fibrinogen, fasting blood glucose, troponin T was significantly higher in femoral artery group than in radial artery group (all P<0.05). The interval between two procedure sessions was significantly longer in the femoral artery group than in the radial artery group (P=0.001). The incidence of CI-AKI tended to be higher in femoral artery group than in radial artery group after the first operation (18.6% (16/87) vs. 11.9% (28/235), P=0.133). CI-AKI incidence after the second operation was similar between the two groups (P>0.05). Multivariate logistic regression analysis showed that interventional approach was not an independent risk factor for postoperative CI-AKI in patients with coronary heart disease undergoing interventional procedures twice within 30 days (P>0.05);STEMI (OR=2.854, 95%CI 1.100-7.404, P=0.031) and diuretics use (OR=4.002, 95%CI 1.470-10.893, P=0.007) were independent risk factors for CI-AKI after the first operation. Conclusion: There is no correlation between the risk of CI-AKI and interventional approaches in patients with coronary heart disease who undergo interventional surgery twice within 30 days.

BACKGROUNDData on the epidemiology of hypertension in Chinese non-dialysis chronic kidney disease (CKD) patients are limited. The aim of the present study was to investigate the prevalence, awareness, treatment, and control of hypertension in the non-dialysis CKD patients through a nationwide, multicenter study in China.

METHODSThe survey was performed in 61 tertiary hospitals in 31 provinces, municipalities, and autonomous regions in China (except Hong Kong, Macao, and Taiwan). Trained physicians collected demographic and clinical data and measured blood pressure (BP) using a standardized protocol. Hypertension was defined as systolic BP ≥ 140 mmHg and/or diastolic BP ≥ 90 mmHg, and/or use of antihypertensive medications. BP < 140/90 mmHg and < 130/80 mmHg were used as the 2 thresholds of hypertension control. In multivariate logistic regression with adjustment for sex and age, we analyzed the association between CKD stages and uncontrolled hypertension in non-dialysis CKD patients.

RESULTSThe analysis included 8927 non-dialysis CKD patients. The prevalence, awareness, and treatment of hypertension in non-dialysis CKD patients were 67.3%, 85.8%, and 81.0%, respectively. Of hypertensive CKD patients, 33.1% and 14.1% had controlled BP to < 140/90 mmHg and < 130/80 mmHg, respectively. With successive CKD stages, the prevalence of hypertension in non-dialysis CKD patients increased, but the control of hypertension decreased (P < 0.001). When the threshold of BP < 130/80 mmHg was considered, the risk of uncontrolled hypertension in CKD 2, 3a, 3b, 4, and 5 stages increased 1.3, 1.4, 1.4, 2.5, and 4.0 times compared with CKD 1 stage, respectively (P < 0.05). Using the threshold of < 140/90 mmHg, the risk of uncontrolled hypertension increased in advanced stages (P < 0.05).

CONCLUSIONSThe prevalence of hypertension Chinese non-dialysis CKD patients was high, and the hypertension control was suboptimal. With successive CKD stages, the risk of uncontrolled hypertension increased.

The chinmedomics method was used to explore the effect of Nanshi capsule on endogenous metabolites of rats with kidney-yang deficiency syndrome, investigate the metabolites and metabolic pathways closely related to kidney-yang deficiency syndrome (KYDS)and identify the therapeutic basis of Nanshi capsule(NPC)as well as its action mechanism for KYDS. The routine biochemical indexes of serum were detected and histomorphology was observed. Based on the chinmedomics technology platform, discriminatory analysis in multivariate modes was conducted for rat blood and urine, thus to investigate the biomarkers of KYDS and the therapeutic effect of NPC against KYDS. Meanwhile, the main constituents of NPC in rat serum were also detected to analyze its correlation between the constituents in vivo and the biomarkers of KYDS, and determine the potential effective compounds for therapeutic effect. Eleven biomarkers of KYDS were identified in the rat models, involving steroid hormone biosynthesis, tryptophan metabolism and tyrosine metabolism. It was found that NPC could regulate steroid hormone biosynthesis, tryptophan metabolism and tyrosine metabolism; PCMS analysis showed that caffeic acid, 2-hydroxy-1-methoxy-anthraquinone, 1-hydroxy-2-methoxyanthraquinone, ferulic acid glucuronide conjugation, deacetylasperulosidic acid, cynaroside, betaine and umbelliferone were the main effective compounds of NPC for KYDS. In this study, cynaroside, betaine, umbelliferone and other compounds in NPC could integrally regulate the disturbance of metabolic profile in KYDS by improving the hormone synthesis, hormone synthesis pathway, hormone synthesis and release pathway in tyrosine metabolism and linoleic acid synthesis pathway in linoleic acid metabolism. These results indicated that the NPC had the characteristics of multi-pathway, multi-target and overall regulation in the treatment of KYDS. Chinmedomics approach can provide methodology support to discover innovative drug from traditional Chinese medicine.

To explore the composition and diversity of the intestinal microflora of Leopoldamys edwardsi in Hainan Island. In November 2019, DNA was extracted from fecal samples of 25 adult Leopoldamys edwardsi (14 males and 11 females) in Hainan Island at the Joint Laboratory of tropical infectious diseases of Hainan Medical College and Hong Kong University. Based on the IonS5TMXL sequencing platform, single-end sequencing (Single-End) was used to construct a small fragment library for single-end sequencing. Based on Reads shear filtration and OTUs clustering. The species annotation and abundance analysis of OTUs were carried out by using mothur method and SSUrRNA database, and further conducted α diversity and β diversity analysis. A total of 1481842 high quality sequences, belonging to 14 Phyla, 85 families and 186 Genera, were obtained from 25 intestinal excrement samples of Leopoldamys edwardsi. At the level of phyla classification, the main core biota of the Leopoldamys edwardsi contained Firmicutes (46.04%),Bacteroidetes (25.34%), Proteobacteria (17.09%), Tenericutes (7.38%) and Actinobacteria (1.67%), these five phyla account for 97.52% of all phyla. The ratio of Helicobacter which occupied the largest proportion at the genus level was 12.44%, followed by Lactobacillus (11.39%), Clostridium (6.19%),Mycoplasma (4.23%) and Flavonifractor (3.52%). High throughput sequencing analysis showed that the intestinal flora of Leopoldamys edwardsi in Hainan Island was complex and diverse, which had the significance of further research.
