Abstract: Objective To analyze the changes of coagulation indicators in patients with hepatitis B complicated with Clonorchis sinensis (C. Sinensis), and provide reference value for diagnosis, drug using and prognosis monitoring. Methods　The patient samples were collected from the Third Affiliated Hospital of Sun Yat-sen University from June 2018 to February 2022 and divided into six groups. They were 40 healthy patients, 47 patients with simple chronic hepatitis B, 47 patients with post-hepatitis B liver cirrhosis, 40 patients with C. Sinensis mono-infection, 30 patients with chronic hepatitis B patients co-infected with C. Sinensis and 27 patients with post-hepatitis B liver cirrhosis patients coinfected with C. Sinensis. Four coagulation indexes, prothrombin time (PT), activated partial thromboplastin time (APTT), thrombin time (TT) and fibrinogen (FIB), were detected and compared among the groups. Results Compared with the healthy group, C. Sinensis mono-infection group had higher level of FIB and delayed PT, APTT; chronic hepatitis B group and chronic hepatitis B patients co-infected with C. Sinensis group had delayed PT, APTT, TT and significant lower FIB, these differences were statistically significant (all P<0.05). Compared with simple chronic hepatitis B group, post-hepatitis B liver cirrhosis and chronic hepatitis B patients co-infected with C. Sinensis had significant delayed PT, APTT, TT and lower FIB (all P<0.05). Compared with the post-hepatitis B liver cirrhosis and chronic hepatitis B patients co-infected with C. Sinensis, post-hepatitis B liver cirrhosis patients coinfected with C. Sinensis group had significant delayed PT, APTT, TT and lower FIB (all P<0.05). Conclusions The coinfection of C. Sinensis will further aggravate the coagulation dysfunction of HBV patients, leading to poor treatment and prognosis. HBV patients will have worse coagulation function in the process to post-hepatitis B liver cirrhosis; Therefore, it is important to pay attention to C. Sinensis co-infection when treating HBV patients, so that further guidance on clinical use and monitoring of prognosis can be provided.

Objective To investigate the clinical effect of mild hypothermia on neonatal bilirubin encephalopathy, and the value of 18F-fluorodeoxyglucose (18F-FDG) positron emission tomography (PET)/CT and amplitude integrated electroencephalogram (aEEG) for diagnosis and evaluation of curative effect. Methods From May, 2013 to December, 2014, 29 newborns with bilirubin encephalopathy were divided into conventional group (n=15) and mild hypothermia group (n=14). The conventional group received conventional therapy, and the other group received mild hypothermia in addition. The aEEG and neuron-specific enolase (NSE) were measured before and after treatment, as well as the glucose metabolism rate with 18F-FDG PET/CT after treatment. Results The NSE was lower after treatment in both groups (t>9.670, P<0.001), and was lower in the mild hypothermia group than in the conventional group (F=46.146, P<0.001). After treatment, sleep-wake cycle (SWC), epileptiform activity and the degree of abnormality were obviously improved (P<0.05), and were better in the mild hypothermia group than in the conventional group (P<0.05). The cerebral glucose metabolism rate was significantly better in the mild hypo-thermia group than in the conventional group (t>2.943, P<0.01). The cerebral glucose metabolism rate was negatively correlated with aEEG and NSE (r>0.640, P<0.05). Conclusion Mild hypothermia therapy could further promote the energy metabolism of brain cells in neonatal bilirubin encephalopathy. 18F-FDG PET/CT and aEEG can be used for early diagnosis and therapeutic evaluation.

OBJECTIVETo observe the effect of Bushen Wenyang Huayu Recipe (BWHR) on hypoxia inducible factor-1α (HIF-1α), proline hydroxylase2 (PHD2), von Hippel Lindau disease (VHL) suppressor gene expressions in endometriosis (EM) rats with Shen yang deficiency blood stasis syndrome (SYDBSS), and to explore the pathogenesis of EM and the mechanism of BWHR for treating EM.

METHODSTotally 50 SD rats were randomly divided into five groups, i.e., the blank control group, the sham-operation group, the model group, the Chinese medicine (CM) group, and the Western medicine (WM) group, 10 in each group. Rats in the blank control group and the sham-operation group were fed routinely. Rats in the rest 3 groups received 30-day "extended refrigerator freezing and ice water immersion" and combined with " autotransplantation" to establish EM rat model with SYDBSS. One Milliliter BWHR at 3.33 g/mL was administered to rats in the CM group by gastrogavage. Gestrinone at the daily dose of 0. 5 mg/kg was administered to rats in the WM group by gastrogavage. Equal volume of normal saline was administered to rats in the model group, the blank control group, and the sham-operation group. The size and morphology of ectopic foci in rats were observed after 4 weeks of medication. Expressions of serum CA125, plasma cyclic adenosine monophosphate (cAMP), and plasma cyclic guanosine monophosphate (cGMP) were detected by radioimmunoassay. Morphological changes of eutopic endometrium and ectopic tissue were observed under the optical microscope by HE staining. Protein expressions and contents of HIF-lα, PHD2, and VHL were detected by immunohistochemical SABC method and Western blot. mRNA expressions of HIF-1α, PHD2, and VHL were detected by RT-PCR.

RESULTSThe ectopic foci grew significantly in the model group. Their volumes were obviously contracted after treated by CM and WM. Compared with the blank control group and the sham-operation group, serum CA125 and plasma cGMP obviously increased, cAMP obviously decreased (P < 0.05); expressions and contents of HIF-1α mRNA and protein all decreased (P < 0.05); mRNA and protein expressions and contents of PHD2 and VHL all decreased in the model group (P < 0.05). Compared with model group, levels of CA125 and cGMP obviously decreased; cAMP levels obviously increased, expressions and contents of HIF-1α mRNA and protein all increased, mRNA and protein expressions and contents of PHD2 and VHL all increased in the WM group and the CM group (P < 0.05). Compared with the CM group, PHD2 protein contents were higher in the WM group (P < 0.05). HIF-1α was negatively correlated with PHD2 (r = -0.799, P = 0.00). HIF-1α was negatively correlated with VHL (r = -0. 625, P = 0.003).

CONCLUSIONSBWHR could effectively treat EM. Its mechanism might be associated with reducing contents of HIF-1α, serum CA125, and plasma cGMP, and up-regulating expressions of PHD2, VHL, and cAMP.

BACKGROUND:Transfusion of bone marrow mesenchymal stem cells may become a novel and effective biological therapy for inflammatory bowel disease in clinical practice. Nevertheless, the oncological safety of the treatment is worrisome, and is a key to determine whether mesenchymal stem cells can be widely used in treatment of inflammatory bowel disease, and deserves further investigation. OBJECTIVE:To evaluate the therapeutic effect of bone marrow mesenchymal stem celltransfusion against inflammatory bowel disease in mouse models, and to clarify the effects of mesenchymal stem cells on tumorigenesis of inflammatory bowel disease. METHODS:Mouse model of colitis was established using Balb/c (H-2d) mice exposed to dextran sulfate sodium. Syngeneic bone marrow mesenchymal stem cells were transfused into mouse model through caudal vein. The therapeutic effect of mesenchymal stem cells was compared and observed, and pathological remission of colitis was evaluated. Mouse model of colitis-driven colon carcinogenesis was established using Balb/c (H-2d) mice exposed to dextran sulfate sodium and azoxymethane. Tumor formation within the murine colon was compared and observed after transfusion of mesenchymal stem cells. RESULTS AND CONCLUSION:In models of dextran sulfate sodium-induced colitis, weight loss and fecal occult blood were lessened in the bone marrow mesenchymal stem cellgroup compared with the phosphate buffered saline group. Histological damage score of colitis was less in the bone marrow mesenchymal stem cellgroup:mucosal structure of distal colon was almost intact under microscope, and there was smal area of epithelial defects and cryptal defects. Inflammatory cellinfiltration, proliferation of capil ary and smal vessels could be observed in mucosa and submucosa. Homing and colonization of mesenchymal stem cells in submucosa of inflamed colon could also be observed by in vivo tracing. In the dextran sulfate sodium/azoxymethane model of colitis-driven colon carcinogenesis, the number of intestinal tumors and tumor load were obviously less in the bone marrow mesenchymal stem cellgroup than in the control group. Results indicated that transfusion of bone marrow mesenchymal stem cells can apparently improve colitis lesions of mice with inflammatory bowel disease and inhibit carcinogenesis of colitis, which may provide theoretical support for the biological safety of mesenchymal stem cells transplantation for inflammatory bowel disease.

OBJECTIVETo analyze the drug-sensitivity-related genes to anti-tumor drugs navalbine (NVB) and docetaxel (Doc) in four SCLC and six NSCLC cell lines.

METHODSThe sensitivity of 4 SCLC lines and 6 NSCLC lines to NVB and to Doc was determined with MTT test. The expression of 1291 anti-tumor drug sensitivity-related genes in the 10 cell lines was assayed by cDNA macroarray technique, and cluster analysis was performed to find the relationship between the results obtained by the above mentioned two measurements.

RESULTS(1) The anti-tumor effect of NVB on the 10 cell lines was apparently better than that of Doc. (2) The drug sensitivity-related genes in these 10 cell lines showed a more close positive correlation with Doc than that with NVB, whereas more genes showed negative correlation with NVB than that with Doc. But in 6 NSCLC cell lines, more genes showed the same positive or negative correlation with the two drugs. (3) 51 genes in the 10 cell lines showed correlation with Doc or NVB. 13 of them had negative correlation with Doc, 11 of them showed positive correlation. 24 of them showed negative correlation with NVB, 3 of them showed positive correlation. 67 genes in 6 NSCLC cell lines showed a correlation with sensitivity to Doc or NVB, among them 34 had negative correlation with Doc, 4 had positive correlation. 25 genes had negative correlation with NVB, 4 had positive correlation. (4) Rab 1, Rab 3, Rho B, Rho C, Rac 1, Rac 2, Gho GDI beta, CD44, integrin alpha5, integrin alpha6, integrin beta5, vinculin showed to be cytoskeleton-related genes differently expressing in SCLC or NSCLC cell lines.

CONCLUSIONThere is obvious difference in the drug sensitivity-related genes to NVB or Doc between SCLC and NSCLC cell lines.

OBJECTIVETo assess the association of TNF-α and IL-1RA SNPs with the risk of silicosis in Chinese workers exposed to silica particles.

METHODSCase-control study design was used to enroll 68 silicotic patients induced by silica particles and 68 healthy workers matched for length of silica particle exposure as controls. Both cases and controls were from the same company in southwest China, and each of them was requested to complete a questionnaire. Blood samples were drawn for genomic DNA extraction from each participant. The genotyping of TNF-α (-238 and -308) and IL-1RA (+2018) was performed using polymerase chain reaction-based restriction fragment length polymorphism (PCR-RFLP) and SYBR green-based quantitative polymerase chain reaction (qPCR), respectively. Unconditional logistic regression model was used to estimate odds ratios (ORs) and their 95% confidential intervals (CI) for SNPs.

RESULTSNo significant differences were found between cases and controls in particles exposure length, body mass index (BMI), and status of smoking and alcohol consumption except for age (P=0.001) and blood type (P=0.042). The frequencies of TNF-α (-238) and IL-1RA (+2018) genotypes in cases were significantly different from those in controls, (P=0.001 and P=0.002, respectively), while a borderline significant difference was found in the frequencies of TNF-α (-308) between cases and controls (P=0.063). The variants of three SNPs increased the risk of silicosis in the Chinese workers exposed to silica particles. The adjusted ORs of TNF-α (-308), TNF-α (-238) and IL-1RA (+2018) were 2.8 (95% CI: 1.1-7.5), 20.9 (95% CI: 1.8-236.4) and 4.0 (95% CI: 1.6-10.1), respectively.

CONCLUSIONIt is suggested that cytokine polymorphisms of TNF-α (-238, -308) and IL-1RA (+2018) are associated with the risk of silicosis in the Chinese workers exposed to silica particles. Further independent studies on the interaction between SNPs and exposure to silica particles with a larger sample size are therefore warranted.

OBJECTIVETo investigate the efficacy of fluticasone propionate aerosol (flixotide) versus budesonide suspension in the treatment of recurrent wheezing caused by bronchiolitis.

METHODSA total of 214 infants with newly diagnosed bronchiolitis were randomly divided into flixotide treatment (106 infants) and budesonide treatment groups (108 infants), and were given aerosol inhalation of flixotide or budesonide for 3 months after achieving remission of clinical symptoms. Another 136 infants with bronchiolitis who did not receive regular inhalation of corticosteroid after achieving remission of clinical symptoms were enrolled as the control group. The follow-up visits were performed for 1 year, and the effects of the two therapeutic methods on recurrent wheezing were evaluated.

RESULTSCompared with the control group, both the flixotide and budesonide treatment groups had significantly fewer times of wheezing episodes within 1 year and a significantly lower recurrence rate of wheezing within the first 3 months after regular inhalation of corticosteroid, but no significant differences were observed between the two treatment groups. The amount of corticosteroid inhaled and hospital costs in the budesonide treatment group were significantly higher than in the flixotide treatment group (P<0.01).

CONCLUSIONSContinuous inhalation of flixotide or budesonide after remission of clinical symptoms in children with bronchiolitis can reduce wheezing episodes and the recurrence of wheezing, and flixotide treatment is superior to budesonide treatment in the aspects of hospital costs and the amount of corticosteroid used.

In order to provide a new method for the identification of Placenta hominis, the COI barcode has been employed to identify the P. hominis medicinal materials and its adulterants. Genomic DNA was extracted from the experimental samples. The COI sequences were amplified and sequenced bi-directionally. Sequence assembly and consensus sequence generation were performed using the CodonCode Aligner. NJ tree was constructed by MEGA6.0 software. COI sequences can be successfully obtained from all experimental samples. The intra-specific variation and inter-specific divergence were calculated. The average intra-specific K2P distance of P. hominis was 0.001 and the maximum intra-specific distance was 0.008. The cluster dendrogram constructed can be seen that the same genus is together, and distinguished from its adulterants. It is concluded that P. hominis and its adulterants can be correctly identified by DNA barcoding method.
