Objective:To study the expressions of serum levels of intedeukin-12 (IL-12),interferon-γ (IFN-γ),erythropoietin (EPO) and ferritin in patients with acute leukemia and its clinical significance.Methods:76 patients with acute leukemia who were treated in our hospital from July 2015 to July 2016 were selected as the observation group,including 31 cases of newly diagnosed group,25 cases of remission group and 20 cases of relapse group.And another 76 cases who had taken the physical examination in our hospital were selected as the control group.Then the levels of serum IL-12,IFN-γ,EPO and ferritin in patients were observed and compared between the two groups.Results:The levels of IL-12 and IFN-γ in the observation group were significantly lower than those of the control group,and the levels of EPO and ferritin were significantly higher than those of the control group (P ＜0.05).The levels of serum IL-12 and IFN-γ in the untreated group and the relapse group were significantly lower than those of the remission group [(84.21± 5.43)pg/mL,(98.7± 7.98)pg/mL VS(112.43± 10.21) pg/mL,(38.54± 3.56)pg/mL,(49.87± 4.02)pg/mL VS(108.32± 8.43)pg/mL](P ＜0.05),and the levels of EPO and ferritin were significantly higher than those of the remission group [(402.32± 42.31) mIU/mL (321.58± 30.21)mIU/mL VS (98.21 ± 9.45) mIU/mLM (653.21 ± 54.24) ng/mLM (512.87 ± 43.45)ng/mL VS (342.15 ± 25.12)ng/mL] (P＜0.05).Conclusion:The serum levels of IL-12 and IFN-γ in patients with acute leukemia were lower,and the expression of EPO and ferritin was higher,and the disease and prognosis could be evaluated by monitoring the changes of these indexes.

Objective: To observe CT manifestations of duodenal bulbar ulcer. Methods: Data of upper abdomen plain and enhanced CT of 44 patients with duodenal bulbar ulcer (ulcer group) and 51 patients without duodenal bulbar ulcer (control group) confirmed with gastroscopy were retrospectively analyzed. The wall thickness, enhancement degree (CT value difference between arterial phase or portal phase and plain scan [ΔCT arterialphase, ΔCT portalphase]), enhancement pattern, CT manifestations of mucosal surface and changes of peripheral fat space of duodenal bulbar intestinal were analyzed and compared between 2 groups. Then ROC curves of parameters statistically different between groups for diagnosis of ulcer were respectively drawn, and AUC was calculated to evaluate the relative diagnostic efficacy. Furthermore, the missed rate of CT diagnosis of ulcer group was calculated. Results: The wall thickness of duodenal bulbar in ulcer group ([7.52±2.30]mm) was greater than that in control group ([2.89±0.75]mm, t=12.76, P<0.01), while there was no statistical differences of ΔCT arterialphase nor ΔCT portalphase between 2 groups (t=-0.27, 0.80, both P>0.05). Layered enhancement, irregular mucosal surface and blurred fat space around duodenal bulbar were more common in ulcer group (χ2=56.12, 65.94, 45.71, all P<0.01). AUC of the wall thickness, enhancement pattern, CT findings of mucosal surface and changes of peripheral fat space of duodenal bulb in diagnosis of ulcer was 0.99, 0.90, 0.93 and 0.84, respectively. CT missed diagnosed 36 cases of duodenal bulbar ulcer, and the rate of missed diagnosis was 81.82%(36/44). Conclusion: Thickened duodenal bulb intestinal wall, layered enhancement pattern, irregular mucosal surface and blurred fat space around are typical CT manifestations of bulbous ulcer. Accurate recognition of CT manifestations of bulbous ulcer is helpful to reducing missed diagnosis.

The clinical data of 5 cases of fulminant type 1 diabetes mellitus were analyzed retrospectively.This disease was characterized by abrupt onset and severe diabetic ketoacidosis.The mean duration from the appearance of hyperglycemic symptoms to first hospital visit was 3.4 days.The mean plasma glucose level was 47.7 mmol/L,but the mean value of HbA_(1C) level was 6.8% at first visit.The mean fasting serum C-peptide was 40.0 pmol/L,and mean serum postprandial C-peptide was 68.0 pmol/L at onset.β-cell function did not recover after 3-26 months of follow-up.

Objective To investigate the clinical efficacy of TCM external treatment combined with Dasangju Mixture in treating mycoplasma pneumoniae pneumonia (MPP) in children. Methods One hundred patients with MPP were randomly divided into control group and treatment group by parallel design, with 50 patients in each group. Patients in control group orally took azithromycin combined with other symptomatic treatment when necessary, 7 d for a course and continuously for 3 courses. Based on the treatment for control group, patients in treatment group were added with TCM external treatment (BL13 and RN17) combined with Dasangju Mixture, while azithromycin was sequentially used just for 2 courses. Other types of treatment lasted for 3 courses. The improvement time of symptoms and signs of the patients were recorded and the therapeutic effects of the two groups were evaluated. Moreover, the serum concentrations of mycoplasma pneumoniae-immune gloulin M (MP-IgM) were determined before and after treatment on the 1st and 21st days. Results The improvent time of fever, and cough and lung sign of the treatment group were more obviously shortened than the control group (P<0.05). The total effective rate was 96.0% (48/50) in observation group and 74.0% (37/50) in control group, with statistical significant difference between the two groups (P<0.05). After treatment, the negative rate of the serum concentration of MP-IgM in the treatment group was 82%, and that of the control group was 58%, with statistical significance between the two groups (P<0.05).Conclusion TCM external treatment combined with Dasangju Mixture can not only significantly improve the clinical symptoms and signs of MPP children patients, but also shorten the disease course, and the efficacy was significant. Meanwhile it can reduce the course and side effects of azithromycin, which provides reference to the administration of antibiotics in children.

Objective To investigate the role of BMSCg on enhancing the implant survival and bacheal epithelium regeneration. Methods After transplanted with cryopreserved 2 weeks and 6 weeks allocraft, PHK-26 labeled 3-5 passage BMSCs were injected into the recipient rats via tail vein. Rats in the control groups were injected with the same amount of PBS.We observed the histology of the transplanted trachea including epithelium growth and regeneration, and the PKH-26 fluorescence levels at the para-anastomotic trachea to evaluate the role of BMSC transplantation on the epithelium regeneration. Results Rats from BMSCs injection group survived a long period. Histological observation showed that the tracheal lumen was covered by psudo-striated ciliated columnar epithelium. The cartilage structure was intact. There are no signs of denaturation and necrosis. In the PBS injection group, epithelium regeneration is better in PBS-6-week group than PBS-2-week group. The longest survival time in PBS-6-week group was 32 days, whereas it was 10 days in PBS-2-week group. In BMSCs injection group, rats in BMSC-6-week groups survived longer than 8-week group(12 rats were terminated at 1 week, 4 weeks and 8weeks as planned). There was one rat who survived and were terminated at the designated 8 weeks time point (there were 8regenerated epithelium was similar in the two BMSC transplanted groups. PKH-26 labeled BMSCs migrated to the implant site and showed red fluorescence, with most red fluorescence shown at the anastomotic part. Conclusion BMSCs can migrate to the impaired tissue to repair it. BMSCs may exert their reparation function via enhancing epithelium regeneration.

Furthermore, Microemulsion Huoxue Zhitong Cataplasm high-dose group and Ethosomes Huoxue Zhitong Cataplasm medium-dose group had good effects on reducing the inflammatory exudate of peritoneal capillary and capillary permeability (P<0.05) in animal models. Conclusion Huoxue Zhitong Cataplasm based on microemulsion/ethosomesnano-technology has good transdermal absorption properties and efficacy.

OBJECTIVETo observe the different effects of water soluble extracts from Cassia obtusifolia and processed C. obtusifolia on anti-oxidation and vasodilatation, and to explore the mechanism of eye-clearing effect.

METHODMice were randomly divided into three groups: normal control group, C. obtusifolia group and processed C. obtusifolia group. Ten male and 10 female mice were in each group. mice were given extracts orally 10 g (20 mL) crude drug/kg for one month, control group were given same volume water. Then the eyeball tissue was harvested to prepare homogenate to test SOD, MDA, LDH and NO. Blood was collected from posterior orbital venous plexus to test ET.

RESULTBoth two kinds of extracts could raise the activity of SOD and LDH, decrease the MDA level. Extracts from C. obtusifolia showed higher effects on above mentioned action. Both two kinds of extracts increased the ratio value of NO/ET significantly, and extracts from processed C. obtusifolia showed higher activity.

CONCLUSIONBoth C. obtusifolia and processed C. obtusifolia extracts show obvious anti-oxidation and vasodilatation effects. These results may support the eye-clearing activity of C. obtusifolia.

Objective:To investigate effects of the autophagy inducer rapamycin and autophagy inhibitor 3-methyladenine on viral structures and biosynthesis of functional proteins in dorsal root ganglia in a guinea pig model of varicella-zoster virus (VZV) infection, and to explore their possible mechanisms.Methods:VZV was cultured and proliferated in human embryonic lung fibroblasts (HELFs) , and peripheral blood mononuclear cells (PBMCs) were isolated from guinea pigs. VZV-HELFs and PBMCs were co-cultured for 18-20 hours, and VZV-PBMCs were collected by centrifugation. Thirty-two guinea pigs were randomly and equally divided into 4 groups (8 mice in each group) : blank control group was injected with autologous PBMCs via the medial canthal venous plexus; autophagy inhibition group, autophagy induction group, and VZV infection group were intraperitoneally injected with 3 mg/kg 3-methyladenine solution, 0.5 mg/kg rapamycin solution, and the same volume of 0.9% NaCl solution respectively, followed 2 hours later by injections with 50 μl of VZV-PBMCs via the medial canthal venous plexus. Fourteen days later, the guinea pigs in each group were sacrificed, and dorsal root ganglion tissues were collected. The transmission electron microscope was used to observe the morphology of virus particles, as well as the morphology and number of autophagic vesicles, Western blot analysis was performed to determine the expression of VZV nucleocapsid protein (NCP) , immediate-early protein 62 (IE62) , and autophagy-related proteins Beclin-1 and p62, and immunohistochemical study to determine the expression of anti-VZV antibodies in VZV-infected dorsal root ganglia. Statistical analysis was carried out by using two-independent-sample t test, one-way analysis of variance, least significant difference- t test or Kruskal-Wallis H test. Results:Nucleocapsid-containing virions and scattered autophagosomes were seen in the dorsal root ganglia in the VZV infection group under the transmission electron microscope. The number of autophagic vesicles significantly differed among the blank control group, VZV infection group, autophagy induction group and autophagy inhibition group ( M[ Q1, Q3]: 0, 5[4, 6], 7[5, 9], 0, respectively; H = 135.60, P < 0.01) , and was significantly higher in the VZV infection group than in the blank control group and autophagy inhibition group (both P < 0.05) , as well as in the autophagy induction group than in the autophagy inhibition group ( P<0.05) , but there was no significant difference between the VZV infection group and autophagy induction group ( P>0.05) . Western blot analysis showed that the expression level of IE62 protein was significantly higher in the VZV infection group (1.49 ± 0.06) than in the blank control group (0.50 ± 0.09, t = 9.17, P < 0.05) ; the expression of anti-VZV antibodies was significantly lower in the autophagy inhibition group than in the autophagy induction group and VZV infection group ( t = 9.24, 7.78, respectively, both P < 0.01) , while there was no significant difference between the autophagy induction group and VZV infection group ( P > 0.05) . Conclusion:Autophagy occurred in the dorsal root ganglia of guinea pigs after VZV infection; the inhibition of autophagy could affect the structure of VZV and decrease the expression of VZV functional proteins in the dorsal root ganglia of guinea pigs.

Objective To evaluate the effect of oral stimulation and abdominal massage on the progress and performance of oral feeding and length of hospital stay in premature infants. Methods A total of 80 premature infants were randomly assigned into experimental group, and control group. The infants in the experimental group ( n=40) received oral stimulation and abdominal massage in addition to the routine care. The infants of control group ( n=40) received routine care of NICU including intermittent feeding, oral support, and postural support, etc.. The corrected gestational ages were compared between two groups when infants of two groups achieved starting oral feeding and full oral feeding. The progress of oral feeding, performance of oral feeding and length of hospitalization were calculated. Results The progress of oral feeding and length of hospitalization were (3.38±1.84)d and (30.25±17.32)d that all were lower than those of control group; the efficacy of feeding, feeding effects and milk volume intake were (6.30±0.94)ml/min, (81.45±21.61)%, (78. 97±18.99)%, which were higher than those of control group (t=-6.317,-2.862,8.543,2.698,2.641;P<0.05) . Conclusions The oral stimulation combined with abdominal massage is beneficial for the difficulty of oral feeding in premature infants.

OBJECTIVETo investigate the antiatherogenic effect and possible mechanisms of the extracts of Radix Salviae Miltiorrhizae (RSM) or Fructus Crataegi (FC), as well as their interaction.

METHODWistar rats were randomly divided into 2 groups: normal group and model group. The atherosclerotic model rats were injected VD3 and ovalbumin, while fed with high cholesterol diet. After the model was determined successfully, all model rats were divided into normal group, model group, Xuezhikang group, RSM group, FC group, mixture of RSM and FC group. Each group was given the corresponding drugs for 4 weeks. After 12 weeks, blood serum were analyzed for total cholesterol (TC), triglyceride (TG), low density lipoprotein cholesterol (LDL-C) and high density lipoprotein cholesterol (HDL-C), superoxide dismutase ( SOD), malondialdehyde (MDA) and nitric oxide (NO). And the blood plasma also analyzed for levels of endothelin (ET), 6-keto prostaglandin F1alpha (6-keto-PGF1alpha), thromboxane B2 (TXB2), C-reactive protein (CRP), interleukin 6 (IL-6), interleukin 8 (IL-8), tumor necrosis factor alpha (TNF-alpha) and so on. At last, the pathological observation of aorta was carried out.

RESULTCompared with those in model group, the TC, TG, LDL-C, ET, TXB2 and MDA levels and TXB2/PGF1alpha ratio were reduced, while the HDL-C, the serum SOD, No and 6-keto-PGF1alpha level were raised in the intervention groups. Although the levels of CRP, IL-6 and IL-8 were lower than model group, there was no obvious effect on the releasing of TNF-alpha.

CONCLUSIONRSM and FC could inhibit the atherogenesis formation and development, which might be due to regulating the lipid metabolism, enhancing the antioxidation, and reducing the release of inflammatory factors.
