Objective To investigate the cognitive, intelligent and cranial MRI status of 4 patients with myotonic dystrophy type 1 (DM1). Methods A pedigree of 4 patients,admitted to our hospital from September 2011 to December 2011 and diagnosed as having DM1, were chosen in our study; Chinese edition tests of Wechsler adult intelligence scale and Wechsler memory scale were used to test the intelligence of these patients; Montreal cognitive assessment (MoCA) and Neurobehavioral cognitive status examination (NCSE) were applied to evaluate the patients' cognitive function.All of the 4 patients received a cranial MRI scan. Results Except for 1 patient,the other 3 patients had low intelligent quotient (IQ) and memory quotient (MQ),and their verbal IQs were all lower than performance IQs.Three patients showed impaired visual space/executive skills,calculation,memory,and conceptual thinking abilities; 1 patient showed impaired sentence repetition and verbal fluency on MoCA,though his final scores were within normal range. Three patients had brain atrophy to some extent on MRI scan,prominently in the frontal lobe and temporal lobe; white matter lesions and thickened skull were founded in all 4 patients. Conclusion Multiple cognition disorders and brain involvements can be found in DM1 patients and deserve further investigation.

OBJECTIVETo prepare cytochrome (CYP)2E1-silenced hepatocytes by lentivirus-mediated RNA interference technology and to investigate the hepatotoxicity of trichloroethylene (TCE) in CYP2E1-silenced hepatocytes.

METHODSShort hairpin RNA fragments were designed and synthesized and were then ligated into the lentiviral vector; single colonies were screened; the plasmid was extracted after PCR and sequence identification and then transferred into L02 hepatocytes; the CYP2E1-silenced hepatocytes were selected; real-time quantitative PCR and Western blot were used to evaluate the interference effects. The obtained CYP2E1-silenced hepatocytes, as well as normal L02 hepatocytes, were treated with TCE (0, 0.25, 0.50, 1.00, 2.00, and 4.00 mmol/L). The cell viability and half maximal inhibitory concentration (IC50) of TCE were measured; the apoptotic rate of cells was measured by flow cytometry; the mRNA expression levels of apoptosis genes and oncogenes were measured by real-time quantitative PCR.

RESULTSThe IC50s of TCE for L02 hepatocytes and CYP2E1-silenced hepatocytes were 15.1 mmol/L and 23.6 mmol/L, respectively. The apoptotic rate increased as the dose of TCE rose in the two types of cells; the CYP2E1-silenced hepatocytes hada significantly lower apoptotic rate than L02 hepatocytes when they were exposed to 2.0 and 4.0 mmol/L TCE (P < 0.05 or P < 0.01). The mRNA expression level of bcl-2 (anti-apoptosis gene) in CYP2E1-silenced hepatocytes was 15% ∼ 60% higher than that in L02 hepatocytes (P < 0.01), while the mRNA expression levels of caspase-3 and caspase-9 (apoptosis genes) in CYP2E1-silenced hepatocytes were 30% ∼ 60% lower than those in L02 hepatocytes (P < 0.01). The mRNA expression level of p53 (cancer suppressor gene) in CYP2E1-silenced hepatocytes was 81 - 278% higher than that in L02 hepatocytes (P < 0.01), while the mRNA expression levels of c-fos and k-ras (oncogenes) in CYP2E1-silenced hepatocytes were 20-68% lower than those in L02 hepatocytes (P < 0.01).

CONCLUSIONCYP2E1-silenced cells can be successfully prepared by lentivirus-mediated RNA interference technology. Silencing CYP2E1 gene can reduce the hepatotoxicity of TCE and inhibit the expression of some apoptosis genes and oncogenes, suggesting that CYP2E1 gene plays an important role in TCE metabolism and is related to the hepatotoxicity of TCE.

Objectives: To investigate the early diagnostic value of neutrophil gelatinase-associated apolipoprotein (NGAL) on contrast induced nephropathy (CIN) in patients after percutaneous coronary intervention (PCI). Methods: A total of 200 patients received coronary angiography (CAG) and PCI in our hospital from 2016-01 to 2017-02 were enrolled and the research included in 2 groups: CIN group, 23 and Non-NCI group, according to 4:1 ratio, 92 patients without NCI. Serum levels of creatinine, blood and urine levels of NGAL were examined and compared at pre-operation and 4 h, 24 h, 48 h and 72 h after the operation between 2 groups. Results: All patients received CAG and CIN occurred in 23/200 (11.5%) patients. Compared with Non-CIN group, CIN group had more patients with elder age, more smokers and diabetes, P<0.05. Pre-operative blood and urine NGAL were both at normal level and it was similar between 2 groups, P>0.05. In CIN group, urine NGAL was significantly increasing at 4 h after operation and gradually increasing to 72 h after operation; blood NGAL was significantly increasing at 4 h after operation, it began decreasing at 24 h after operation and remained a relatively high level at 72 h after operation; post-operative blood and urine levels of NGAL were different from pre-operative condition at each time points, all P<0.05. In Non-CIN group, post-operative blood and urine levels of NGAL were similar to pre-operative condition, P>0.05. Post-operative blood and urine NGAL were different at the same time point between 2 groups, P<0.01. AUC of ROC for post-operative urine NGAL at 4h, 24h, 48h and 72h were 0.908, 0.926, 0.931 and 0.957 respectively, the sensitivity and specificity for CIN diagnosis were 91.3% and 100% at 4 time points; AUC of ROC for post-operative blood NGAL at 4 h and 24 h were 0.964 and 0.913, the sensitivity and specificity for CIN diagnosis were 87.3% and 100% at both time points. Conclusions: Blood and urine levels of NGAL may reflect renal function changes earlier than serum creatinine in CAG/PCI patients, it had the higher sensitivity and specificity for CIN diagnosis and could be used as the early predictor for CIN occurrence.

To systemically evaluate the efficacy and safety of Cinobufacini Injection in combination with platinum-contained first-line chemotherapy for treatment of non-small cell lung cancer(NSCLC). The randomized controlled trials(RCT) about the Cinobufacini in combination with platinum-contained first-line chemotherapy(versus chemotherapy alone) were collected through PubMed,Cochrane library,CNKI,VIP,CBM,and Wan Fang Database from database inception to December 2018. Two researchers extracted data and assessed the literature quality separately,and made a Meta-analysis by using Rev Man 5. 3 software. Twenty-seven RCTs were included in the present review,involving 2 125 patients,1 082 in treatment group and 1 043 in control group. The Meta-analysis results showed that as compared with chemotherapy alone,the combination of Cinobufacini and platinum-contained first-line chemotherapy could enhance one year survival rate(RR = 1. 34,95%CI[1. 17,1. 55],P< 0. 01),two year survival rate(RR = 1. 84,95% CI[1. 31,2. 59],P<0. 01),objective tumor response rate(RR = 1. 47,95%CI[1. 33,1. 63],P<0. 01); improve the quality of life for patients(RR =1. 54,95%CI[1. 37,1. 72],P < 0. 01); and reduce the incidences of WBC toxicity(RR = 0. 63,95% CI[0. 49,0. 80],P < 0. 01),platelet toxicity(RR = 0. 54,95%CI[0. 35,0. 84],P<0. 01),gastrointestinal reactions(RR = 0. 60,95%CI[0. 45,0. 80],P<0. 05),pain(RR = 1. 68,95% CI[1. 38,2. 03],P< 0. 01),and hair loss reaction(RR = 0. 76,95% CI[0. 59,0. 98],P < 0. 05). The results showed that for the treatment of NSCLC,the addition of cinofacini to conventional platinum-contained chemotherapy can increase the long-term and short-term efficacy of chemotherapy,improve the quality of life for patients,and reduce the side effects of platinumbased chemotherapy drugs. However,more high quality and large-scale randomized controlled trials are required to verify this conclusion in the future.

OBJECTIVE: To investigate the effect of hemoglobin (Hb) on the efficacy of chimeric antigen receptor T cell therapy (CAR-T) in patients with multiple myeloma (MM). METHODS: From June 2017 to December 2020, 76 MM patients who received CAR-T therapy in the Department of Hematology, The Affiliated Hospital of Xuzhou Medical University, with complete clinical data and evaluable efficacy, were selected as the research objects. According to the receiver operating characteristic (ROC) curve, the best cut-off value was obtained. The patients were divided into groups on the basis of Hb 105.5 g/L as the cut-off value. The age, sex, serum calcium, β₂-microglobulin, serum creatinine, lactate dehydrogenase (LDH), and the influencing factors of CAR-T treatment efficacy in MM patients were analyzed. RESULTS: Hb was an influencing factor of efficacy. Univariate analysis showed that Hb, LDH, and albumin affected the efficacy of CAR-T therapy. Multivariate analysis showed that Hb ( OR=1.039, 95% CI: 1.002-1.078) and LDH ( OR=1.014, 95% CI: 1.000-1.027) were the influencing factors for the efficacy of CAR-T therapy. CONCLUSION The efficacy of CAR-T therapy in MM patients with low Hb is poor, and Hb is a factor affecting the efficacy of CAR-T therapy.

OBJECTIVE: To observe the effects of electroacupuncture at "Siguan" points on behavior, colonic 5-hydroxytryptamine (5-HT) and fecal short-chain fatty acids (SCFAs) in rats with post-stroke depression (PSD), and explore the effect mechanism of electroacupuncture at Siguan points on PSD. METHODS: Fifty SD rats were randomly divided into a sham-operation group, a stroke group, a PSD group, a drug group and an electroacupuncture group, with 10 rats in each one. The stroke model was established by middle cerebral artery occlusion (MCAO) method in the stroke group; except for the sham-operation group, the rats in the other groups were intervened with MCAO combined with solitary and chronic unpredictable mild stress (CUMS) to establish PSD model. In the electroacupuncture group, electroacupuncture was delivered at "Hegu" (LI 4) and "Taichong" (LR 3), with disperse-dense wave, 2 Hz/10 Hz in frequency, for 30 min in each intervention, once daily, for consecutive 21 days. Simultaneously, distilled water (0.01 L•kg^-1•d^-1) was administrated intragastrically. Fluoxetine solution (2.33 mg•kg^-1•d^-1) was given by gavage , once a day and for 21 days in the drug group. The same procedure of fixation and gavage with distilled water were adopted in the sham-operation group, the stroke group and the PSD group. Separately, before stroke modeling, after PSD modeling and after 21-day intervention, the consumption of sugar water and the scores of horizontal movement and vertical movement in open-field test were observed. After 21-day intervention, the content of colonic 5-HT was detected by immunohistochemical method, and that of fecal SCFAs was determined by gas chromatography mass spectrometry. RESULTS: After PSD modeling, compared with the stroke group, the sugar water consumption, the horizontal movement scores and vertical movement scores of the open-field test were all reduced in the PSD group, the drug group and the electroacupuncture group (P<0.05). After 21-day intervention, the sugar water consumption and the scores of horizontal movement and vertical movement of the open-field test were increased in the drug group and the electroacupuncture group (P<0.05) when compared with the PSD group; and the horizontal movement score in the electroacupuncture group was lower than that of the drug group (P<0.05). Compared with the sham-operation group, the contents of total fecal SCFAs and acetic acid were lower in the stroke group (P<0.05), and the contents of colonic 5-HT and total fecal SCFAs, acetic acid, propionic acid and butyric acid were reduced in the PSD group (P<0.05). In comparison with the PSD group, the contents of colonic 5-HT and total fecal SCFAs, acetic acid and propionic acid were increased in the drug group and the electroacupuncture group (P<0.05); and the content of colonic 5-HT in the electroacupuncture group was lower than that of the drug group (P<0.05). The level of colonic 5-HT was positively correlated with the contents of total fecal SCFAs and propionic acid (r=0.424, P=0.005; r=0.427, P=0.004). CONCLUSION Electroacupuncture at "Siguan" points can relieve the depression-like behavior of PSD rats, and its underlying mechanism may be related to the regulation of fecal SCFAs, which affects the release of colonic 5-HT.

Fermented Chinese medicine has long been used. Amid the advance for preservation of experience, the connotation of fermented Chinese medicine has been enriched and improved. However, fermented Chinese medicine prescriptions generally contain a lot of medicinals. The fermentation process is complicated and the conventional fermentation conditions fail to be strictly controlled. In addition, the judgment of the fermentation end point is highly subjective. As a result, quality of fermented Chinese medicine is of great difference among regions and unstable. At the moment, the quality standards of fermented Chinese medicine are generally outdated and different among regions, with simple quality control methods and lacking objective safe fermentation-specific evaluation indictors. It is difficult to comprehensively evaluate and control the quality of fermented medicine. These problems have aroused concern in the industry and also affected the clinical application of fermented Chinese medicine. This article summarized and analyzed the application, quality standards, and the modernization of fermentation technology and quality control methods of fermented Chinese medicine and proposed suggestions for improving the quality standards of the medicine, with a view to improving the overall quality of it.
