Objective To investigate the effects of early hemofiltration combined with traditional Chinese medicine on nasal feeding on severe acute pancreatitis (SAP) patients. Methods Seventy four patients were divided into traditional Chinese medicine group (group A, 35 cases) and traditional Chinese medicine+hemofiltration group (group B, 39 cases). In group A, patients were given a serious of procedure including fasting, gastrointestinal decompression, fluid resuscitation, inhi-bition of pancreatic secretion, antibiotic prophylaxis, parenteral nutrition and traditional Chinese medicine on nasal feeding;In group B, patients received continuous veno-venous hemofiltration treatment(also called Continuous Renal Replacement Therapy,CRRT) in addition to the procedures receiving by group A. On admission and the first, 3rd, 7th days post-treatment, the scores of acute physiology and chronic health evaluation (APACHEⅡ), tumor necrosis factor-α(TNF-α), interleukin-6 (IL-6), interleukin-8 (IL-8) levels were recorded. Length of hospital stay, local and systematic complications, surgical inter-vention, mortality and hospitalization expenses were compared between two groups. Results On admission, no statistical significance was seen in the hematocrit, white blood cell count, lactic acid dehydrogenase, blood urea nitrogen, blood glu-cose, APACHEⅡscore, Ranson’s score and classification of etiology between these two groups (P>0.05). But APACHEⅡ, TNF-α, IL-6, IL-8 were decreased significantly in group B than in group A, after the first, 3rd, 7th days post-treatment (P<0.05). Compared with group A, the length of hospital stay, local complications, systemic complications, surgical interven-tion, mortality and hospitalization expense were lower in group B. Conclusion Traditional Chinese medicine on nasal feed-ing combined with early hemofiltration could effectively reduce complications, incidence of organ dysfunction and could im-prove the prognosis of SAP patients.

The aim of the present study is to investigate the effects of adiponectin (APN) on hypoxia/reoxygenation (H/R) injury in cultured cardiomyocytes. Primary cardiomyocytes were obtained from neonatal rats by enzymatic digestion method and identified by immunofluorescent technique. Primary cells cultured for 72 h were used in experiment and divided into 5 groups randomly: Control group, H/R group, H/R+APN group, H/R+APN+adenine 9-beta-D-arabinfuranoside (AraA, AMPK inhibitor) group, and H/R+AraA group. The cardiocyte morphology and beating rate were observed under inverted microscope. The DNA ladder was examined by agarose gel electrophoresis, and the cell apoptosis was determined by flow cytometry. Moreover, the malondialchehyche (MDA) content in myocardial cells and the superoxide dismutase (SOD) activity in the supernatant were measured using kits, the fluorescence intensity of intracellular Ca2+ was observed by laser scanning confocal microscope, and the phosphorylation of AMPK was determined by Western blotting. Compared with control group, H/R group showed increased apoptotic rate, oxidative stress level, intracellular Ca2+ concentration and phosphorylation level of AMPK (P<0.05), while significant ameliorations in the above indices were seen in H/R+APN group. On the contrast, AraA attenuated the protective effect of APN and decreased the phosphorylation of AMPK. These results suggest that adiponectin can protect cardiomyocytes from H/R-induced oxidative stress and apoptosis through AMPK pathway.

Journal of Forensic Medicine 2020;36(3):354-359
Forensic palynology is to apply palynology to the field of forensic science, using pollen and spores to solve issues in juridical practice, such as civil and criminal issues. Sporopollens have a small size, wide distribution, diverse morphology, can be easily transferred, have durability, and is not easily noticed. It can provide strong investigation and related evidence for case detection as good trace evidence. The application of palynology in forensic science has achieved certain success, but it is underutilized in most countries. This paper analyzes the evidence value provided by sporopollen, collection of the sporopollen samples, the progress in detection technology and challenges ahead, based on the biological characteristics of sporopollen, combined with recent successful cases in forensic science, to comprehensively discuss the research progress in forensic palynology and its application prospects in forensic science.

OBJECTIVETo investigate the expression of suppressor of cytokine signaling(SOCS)-3 and caspase-3 and their correlative significance in endometriosis.
METHODSImmunohistochemical EnVision method was used to detect the SOCS-3 and caspase-3 protein expression in ectopic and eutopic endometrium (n = 32) of patients with endometriosis, as well as normal endometrium (n = 30) of women without endometriosis.
RESULTSSOCS-3 and caspase-3 proteins were expressed in all three groups and not affected by the menstrual cycles. The expression of SOCS-3 in ectopic endometrium (5.54 ± 2.12) was significantly lower than that in eutopic (7.39 ± 1.09, P = 0.001) and control group (7.48 ± 1.26, P < 0.01), but without difference between the eutopic and control group (P = 0.756). SOCS-3 expression in ectopic and eutopic endometrium was significantly lower in III/IV stages than that in I/II stages of endometriosis (P < 0.05). Significantly lower expression of caspase-3 protein was found in ectopic (3.20 ± 1.24) and eutopic endometrium (3.88 ± 1.93) as compared with the control group (6.49 ± 1.85, P < 0.01), however ectopic and eutopic endometrium showed no significant difference (t = 1.66, P = 0.10). There was no significant difference of the expression of caspase-3 in ectopic and eutopic endometrium at different disease stages (P > 0.05). Positive correlation was found between the expression of SOCS-3 and caspase-3 proteins in ectopic endometrium (r = 0.655, P < 0.01).
CONCLUSIONSOCS-3 may be involved in the development of endometriosis through inhibition of apoptosis of ectopic endometrial cells.

Primary central nervous system germ cell tumors (CNS-GCTs) in children and adolescents have unique clinical features and methods of treatment compared with those in adults. There is little information about Chinese children and adolescents with CNS-GCTs. Therefore, in this study we retrospectively analyzed the clinical features and treatment outcome of Chinese children and adolescents with primary CNS-GCTs. Between January 2002 and December 2012, 57 untreated patients from a single institution were enrolled. They were diagnosed with CNS-GCTs after pathologic or clinical assessment. Of the 57 patients, 41 were males and 16 were females, with a median age of 12.8 years (range, 2.7 to 18.0 years) at diagnosis; 43 (75.4%) had non-germinomatous germ cell tumors (NGGCTs) and 14 (24.6%) had germinomas; 44 (77.2%) had localized disease and 13 (22.8%) had extensive lesions. Fifty-three patients completed the prescribed treatment, of which 18 underwent monotherapy of surgery, radiotherapy, or chemotherapy, and 35 underwent multimodality therapies that included radiotherapy combined with chemotherapy or surgery combined with chemotherapy and/or radiotherapy. PEB (cisplatin, etoposide, and bleomycin) protocol was the major chemotherapy regimen. The median follow-up time was 32.3 months (range, 1.2 to 139 months). Fourteen patients died of relapse or disease progression. The 3-year event-free survival (EFS) and overall survival rates for all patients were 72.2% and 73.8%, respectively. The 3-year EFS was 92.9% for germinomas and 64.8% for NGGCTs (P = 0.064). The 3-year EFS rates for patients with NGGCTs who underwent monotherapy and multimodality therapies were 50.6% and 73.5%, respectively (P = 0.042). Our results indicate that multimodality therapies including chemotherapy plus radiotherapy were better treatment option for children and adolescents with CNS-GCTs.

The influence on 10 kinds of ginsensides of different processed methods of Panacis Quinquefolii Radix was discussed. White Panacis Quinquefolii Radix (sliced and dried at -80 °C), red Panacis Quinquefolii Radix( steamed, sliced and dried at -80 °C) and commercial Radix Panacis Quinquefolii (dried by electric blast air) processed by different methods. HPLC-PDA-ESI- MS method was established before by our team. Ten kinds of ginsenosides of them were determined. The content of total ginsenosides were as follow: commercial Panacis Quinquefolii Radix > white Panacis Quinquefolii Radix > red Panacis Quinquefolii Radix. Compared with white Panacis Quinquefolii Radix, the content of Re, Rc, Rb3 and Rb2 of Red Radix Panacis Quinquefolii decreased but increased that of Rg,, Rb1. Both Rg2 and Rg, were not found in white Panacis Quinquefolii Radix and commercial Panacis Quinquefolii Radix by PDA detector, and low response in ESI-MS, while red Panacis Quinquefolii Radix was to the high content that of 0. 027% and 0.040 1%. The constituent of RA0 of red Panacis Quinquefolii Radix was higher than the other two. After Panacis Quinquefolii Radix processed, the kind and content of ginsensides were significantly changed. The constituent of some kinds of ginsensides was increased and some decreased. Rf was not found in all Panacis Quinquefolii Radix samples which were consistent with the former documents.

OBJECTIVETo investigate the effect of YB-1 on the transcription of induced mdr1 gene expression in K562 cells.
METHODSK562 cells were treated with doxorubicin (DOX) at different concentrations and times. Expression of mdr1 and YB-1 genes was examined by RT-PCR and P-glycoprotein (P-gp) by flow cytometry. Cyto/nuclear protein was extracted for YB-1 detection by Western blotting. The expression of YB-1 gene in K562 cells was inhibited by YB-1 gene specific RNA interference (RNAi), then the expression of mdr1 and P-gp in YB-1 gene silenced cells treated with DOX was detected.
RESULTSThe mdr1 gene as well as its corresponding protein P-gp was highly expressed in DOX exposed K562 cells. DOX up-regulated the expression of YB-1 gene, and promoted YB-1 protein nuclear translocation. On YB-1 gene silenced, the expressions of mdr1 gene and P-gp were obviously down-regulated in DOX treated K562 cells.
CONCLUSIONDoxorubicin can induce the expression of mdr1 gene in K562 cells, which may result from the transcription of mdr1 gene by activated YB-1.
