Objective To study the phase transformations and chemical composition changes of Pyritum Preparata (PP) influenced by different processing. Methods To analyse the changes of microstructure, morphology, mineral phase, and chemical compositions in different PP by ore microscope, electron probe microanalyzer technique. Results Greater changes have taken place in chemical compositions of PP after calcination: pyrite (FeS_2) changed into pyrrhotite (Fe_(1-x)S), even changed into magnetite (Fe_3O_4); and chalcopyrite generated mutation to be low-copper chalcopyrite, the contents of Cu reduced, the rate of Cu/Fe changed. At the same time, in the pyrrhotite around the mutative chalcopyrite, the contents of Cu increased. That is to say, the Cu got into pyrrhotite and generated solid-solution with high dispersion, and then ore became loose and porous. In the hard-burned spot of calcined quenched samples by vinegar, the contents of Pb and S are far lower than non-burned spot, the minimum estimate of Pb is less than 1/10 of crude ore. Conclusion There is a co-relativity between phase transformations and dissolution of chemical compositions before and after calcining PP.

Background Corneal neovascularization (CNV) is one of the causes of corneal blindness.Studies showed that ADP-ribosylation factor (ARF) can regulate the growth of tumor cells,and inhibiting ARF will decrease angiogenesis.However,whether ARF antagonist plays an action on CNV is unclear.Objective The aim of this study was to explore the effect and mechanism of ARF inhibitor on alkali-burn induced CNV.Methods Sixty clean male BABL/c mice aged 7-8 weeks were divided into PBS group and ARF antagonist group according to randomized number table.CNV models were induced by NaOH burn method in all the mice.ARF at the concentration of 0.5 g/L(0.5 ml) was intraperitoneally injected 3 times per week for 1 week followed the induction of CNV in the ARF antagonist group,and 0.5 ml PBS was used in the PBS group.CNV was examined 2,4,7,14 days after injection by the slit lamp microscope and the CNV related area in the cornea was calculated.Betore modeling(0 day) and 4,7,14 days after modeling,real-time PCR and Western blot were used to analyze the expressions of ARF mRNA and protein in the corneas.Forteen days after modeling,the expression of the CD31 in the CNV was detected using immnofluorescence of corneal whole mount;the expression of vascular endothelial growth factor(VEGF) in the cornea was assayed by Western blot.Cellular wound scratch test was employed to evaluate the effects of ARF antagonist on proliferation and migration of human retinal vascular endothelial cells (RECs).All animal experiments were done in accordance with the ARVO Statement for the Use of Animals in Ophthalmic and Vision Research and Guideline for the Care and Use of Laboratory Animals on the the Soochow University Animal Care Committee.Results ARF mRNA and protein were expressed in the mice corneas in both the PBS group and the ARF antagonist group at various time points.The expression of ARF mRNA in mice corneas was enhanced with the lapse of the time (Ftime =65.17,P =0.00),but no significant difference was found among the groups (Fsroup =1.98,P=0.18).There was also significant difference in the expression of ARF protein in mice corneas at different time points in the ARF antagonist group (F =10.77,P =0.00).The related CNV area was 0.45±0.05 in the ARF antagonist group,and that in the PBS group was 0.72±0.11,with significant difference between them (t =-3.87,P ＜ 0.05).The green fluorescence area of C D31 expression in the cornea was smaller in the ARF antagonist group than that of the PBS group.Expression level of VEGF in the ARF antagonist group was 1.20±0.21,and that in the PBS group was 2.47±0.33,showing a significant difference (t =-5.62,P ＜ 0.05).As the increase of ARF antagonist concentration,the inhibiting rate of cell proliferation was reinforced among 10,100 and 1 000 μg/L ARF antagonist groups (F=8.47,P =0.02).Twenty-four hours after scratch test,the migrating distance of human RECs was (5.46±1.32) μm and (5.04±1.68) μm in the 100 μg/L and 1 000 μg/L ARF antagonist groups,respectively,which were shorter than (8.49± 1.18) μm of the PBS group (t=-2.94,-2.91,both at P＜0.05).Conclusions ARF inhibitor can reduce CNV by down-regulating the expression of VEGF in alkaline burn cornea and inhibiting the proliferation and migration of vascular endothelial cells.

Background The pathogenesis and mechanism research of corneal neovascularization is of important significance for the prevention and management of corneal neovascularization.Some relative researches are being performed on non-corneal neovascularization-derived vascular endothelial cells, so the results are affected to a certain extent.Objective This study was to isolate and culture vascular endothelial cells from experimental corneal neovascularization tissue and detect the expression of chemokine receptors in vitro.Methods Corneal neovascularization models were established on 10 SPF male BALB/c mice with the age of 7-8 weeks by sticking the filter papers with NaOH on the central corneas, and then the immunofluorescence technique was use to assay the CD31 expression in corneal flatmount 2 weeks after modeling.Corneal pieces were made in 2 weeks after alkali burn and then were digested by collagenase type D.Vascular endothelial cells were isolated from neovascularized tissue by affinity purification using magnetic beads coated with anti-CD31.The cells were cultured on fibronectin-coated walls and then identified by immunocytochemistry.Reverse transcription-PCR was employed to detect the expressions of chemokine receptors in the cells.The use and care of the animals complied with ARVO Statement and this experimental procedure was approved by Soochow University Animal Care Committee.Results Corneal neovascularization occurred at 7 days and peaked at 2 weeks after modeling, and immunofluorescence exhibited the green network-like fluorescence for CD31 antibody in corneas.The cells grew against the wall 2 hours after culture with the polygon shape and large dimension, and the growth obviously quickened after passage.The cultured cells showed the positive response for CD31 antibody, showing the brown dye in cytoplasm,in contrast,the expression of CD31 was absent in corneal stromal cells.Chemokine receptors were positively expressed in the cells with the strongest expression levels in CCR1 ,CCR2,CCR3 and CCR4 mRNA and the weakest expression levels in CCR9,CXCR4 and CXCR5 mRNA,while CXCR3, CCR6, CCR10 and CX3CR1 mRNA were expressed with the moderate intensity.Conclusions Vascular endothelial cells can be obtained from experimental neovascularized corneas by affinity purification and express chemokine receptors,which facilitate the study of their biological properties.

Objective To observe the clinical efficacy of wrist-ankle acupuncture in treating pain due to laparoscopic cholecystectomy.Method Totally 150 patients who were going to receive laparoscopic cholecystectomy were randomized into group A, group B, and group C, 50 cases in each group. Group A was intervened by wrist-ankle acupuncture prior to anesthesia, with the needles retained for 12 h; group B was by subcutaneous needling at the area nearby the points prior to anesthesia, with the needles retained for 12 h; group C didn’t receive any intervention before anesthesia. For the three groups, general inhalational and intravenous anesthesia was adopted for surgery, and patient-controlled intravenous analgesia for post-operation analgesia. The incision pain and visceral pain in the three groups were recorded by using Visual Analogue Scale (VAS) respectively 1 h, 2 h, 4 h, 8 h, 12 h, 24 h, 36 h, and 48 h after the operation. The total effective rate, analgesics consumption after operation, and incidence rate of adverse reaction were compared.Result There were significant differences in comparing the VAS scores of incision pain and visceral pain between group A and group C 4 h, 8 h, 12 h, 24 h, and 36 h after the operation (P<0.01,P<0.05). Between group A and group B, there were significant differences in comparing the VAS score of incision pain 8 h, 12 h, 24 h, and 36 h after the operation and the VAS score of visceral pain 12 h, 24 h, and 36 h after the operation (P<0.05). The total effective rate was 96.0% in group A, which was significantly different from 84.0% in group B and 86.0% in group C (P<0.05). The consumption of Fentaneyl citrate injection was (52.4±10.8)μg in group A, which was significantly different from (92.2±11.0)μg in group B and (107.2±11.5)μg in group C (P<0.05,P<0.01). The incidence rate of adverse reactions was 12.0% in group A, which was significantly different from 58.0% in group B and 66.0% in group C (P<0.01).Conclusion Wrist-ankle acupuncture plus patient-controlled intravenous analgesia can mitigate pain after laparoscopic cholecystectomy, and thus it can be taken as one of the post-operational analgesic approaches.

Background Intracorneal macrophages play a critical role in corneal neovascularization (CNV)by secreting relative chemokines.But macrophages are characteristic by heterogeneity which has different biologic functions under different induction or stimulation from microenvironment.Objective This study was to detect the effects of chemokine (C-X3-C motif) ligand 1 (CX3CL1) and chemokine (C-C motif) ligand 2 (CCL2) on macrophages in vitro.Methods CNV was induced by corneal alkali burn in the left eyes of 20 male BALB/c mice aged 7-8 weeks.The CNV was evaluated under the slit lamp microscope 4 days after alkali burn,and then the corneal sections were prepared after mice were sacrificed.The expressions of CCR2 and CX3CR1 in the corneal specimens were detected by histo-fluorescence staining.Human peripheral blood mononuclear cells were separated using density gradient centrifugation and incubated in RPMI-1640 medium containing 10％ fetal bovine seruml(FBS) with 30 μg/L granulocyte-macrophage colony-stimulating factor (GM-CSF).The cells were divided into CD68 +CCR2 group and CD68+CX3CR1 group,and the percentage of the CX3CR1 and CCR2 expressions in the infiltrated macrophages of corneal specimens and human monocyte-derived macrophages was assayed by flow cytometry.The cultured cells were stimulated using human recombinant CX3CL1 and CCL2 proteins,and real-time PCR was used to detect the relative expressions of angiogenesis-related factors in macrophages.Results CNV was found in corneas 4 days after alkali burn and the CNV onsets from corneal limbus to central zone observed by a slit lamp.CCR2 and CX3CR1 were expressed in the F4/80-positive macrophages in alikali burned corneas.The macrophages grew for two weeks and appeared more dead cells in without GM-CSF group,but in GM-CSF induced group,the number of macrophages was increased.The percentage of CX3CR1-positive cells was 75％ and that of CCR2-positive cells was 45％.Real-time PCR showed that expression level of vascular endothelial growth factor (VEGF) mRNA increased and that ADAMTS-1 mRNA or TSP-1 mRNA decreased on macrophages after CCL2 stimulation,with significant differences in the 150 mg/L CCL2 group compared with the control group (t =-5.09,P =0.03 ; t =3.01,P =0.04 ; t =4.27,P =0.02).However,the VEGF mRNA expression decreased and ADAMTS-1 mRNA and TSP-1 mRNA increased after CX3CL1 stimulation,showing significant differences between the 150 mg/L CX3CL1 group and the control group (t=6.35,P=0.O2;t=-2.92,P=0.04; t=-3.81,P=0.03).Conclusions These results suggest that the macrophages have high heterogeneity.CCL2-and CX3CL1-expressing macrophages can regulate the expressions of angiogenesis-related factors.Macrophage chemokine signal may be a good target for treatment of neovascular ocular disease.

ObjectiveTo evaluate the association between Cyclin D1 G870A polymmphism and risk of colorectal cancer.MethodsExtensive searches of relevant studies on datebase like PubMed,EMCC and CNKI were performed.Case control studies involving unrelated subjects and genotype frequencies in control group consistent with Hardy-Weinberg equilibrium were included for the meta-analysis.Twenty-three case-control studies with 6 344 cases and 9 018 controls were analyzed by the fixed-effect or random-effect meta-analysis method.The metaanalysis was applied with RevMan 5.0 software for heterogeneity test.AA and GA were compared with those with GG genotype.Pooled OR value and 95％ confidence interval (CI) were calculated.ResultsThere were statistical differences between AA & GA and GG.The pooled OR value was 1.10 (95％CI:1.01-1.19,P =0.02).The values were analyzed hierarchically according to different populations.The pooled OR value of Asian was 1.11 (95％ CI:0.98-1.26,P=0.11).The pooled OR value of American was 1.13(95％CI:0.97-1.32,P=0.12).The pooled OR value of European was 1.06(95％CI:0.89-1.25,P =0.52).The pooled OR value of Oceanian was 1.05(95％ CI:0.80-1.38,P=0.73).The values were analyzed hierarchically according to the comparison basis.The pooled OR value of hospital-based was 1.07 (95％ CI:0.95-1.20,P =0.28).The pooled OR value of population-based was 1.13 (95％CI:1.01-1.26,P=0.04).ConclusionThe Cyclin D1 G870A polymorphism is correlated with the susceptibility of colorectal cancer risk at the aggregate level analysis.Analysis by different methods:according to different populations,every group don't support the correlation.According to comparison basis,there has no correlation in hospital-based group,but there has correlation in population-based group.

Objective To evaluate the diagnostic utilities of CD64,CDllb,sICAM-1 and sE-selectin in early identification of neonatal sepsis related to bacterial infection. Methods The group of sepsis consisted of 36 newboms and the control group included 26 healthy newboms. The blood samples were collected right after being admitted to hospital and at recovery stage in the group of sepsis,as for the control the blood samples were collected only once in the study. In the sepsis group,blood samples were also taken in bacterial culture before treatment CD64 and CDllb were quantified with direct immunofluorescence staining and the whole blood cell flow cytometry analysis. sICAM-1 and sE-selectin level were determined by ELJSA assay,along with CRP. Results The expression level of CD64 in neonates with sepsis was (60. 37 22. 70) .shown in MFI,which was significantly higher than that in the group of control (23. 14 ±5. 10) MFI(P <0. 01). The expression level of CDllb in neonates with sepsis was (1645. 14 ±463. 68) MFI,which was significantly higher than that in the group of control (1041.48 ±260. 34) MFI (P < 0. 01). The concentration of blood sICAM-1 in neonates with sepsis was (240. 20 ± 83.46) μg/L, which was significantly higher than that in the group of control (100. 24 ±51.03)μg/L(P <0. 01). The concentration of blood sE-selectin in neonates with sepsis was (29. 63 ±9. 88μg/L,which was significantly higher than that in the group of control (14. 12 ±5. 33)μg/L(P <0. 01). In the sepsis group,the level of CD64,CDllb,sICAM-l and sE-selectin in the primary stage was higher than the recovery stage significantly (P <0. 01). The sensitivity of above-mentioned molecular markers were 95. 7% , 82. 6% , 81. 8% and 87. 0% , respectively, and the specificity were 95. 8% , 79. 2% ,86.9% and 79.2% . CD64 was the best one. Conclusions CD64 may serve as one of the reliable biomarkers in the early diagnosis of neonatal sepsis, and it may play important role in the treatment of neonatal sepsis.

Objective:To compare the effect of age on clinical outcome of laparoscopic sleeve gastrectomy (LSG) in the obese patients.Methods:A total of 113 patients who underwent LSG due to obesity and metabolic disorders between 2013 and 2018 at Fudan University Pudong Hospital, and completed the scheduled follow-up (1, 3, 6, and 12 months after surgery) were included for the retrospective analysis. The patients were divided into three groups based upon pre-operative age, including 15 to 30 year-old group ( n=58), 31 to 45 year-old group ( n=32), and 45 to 65 year-old group ( n=23). The body weight related parameters, glycemic and metabolic related parameters, lipid panel as well as arterial blood pressure were compared at pre-operative baseline, 1, 3, 6, and 12 months after surgery. The quantitative data were analyzed by repeated measurement ANOVA, and the P value was corrected by Bonferroni method. And the categorical variables were analyzed by chi square test. Results:The preoperative baseline data showed that with the increase of age, the preoperative body mass index gradually decreased, which were (40.1±5.9) kg/m 2, (37.1±6.6) kg/m 2 and (35.3±7.4) kg/m 2 in 16 to 30, 31 to 45 and 46 to 65 year-old groups, respectively. Otherwise, other metabolic related parameters were comparable. At 12 months after LSG, there was no significant difference in the amount of weight loss among the groups, but the percentage of total weight loss (% TWL) and the percentage of total BMI loss (%TBMIL) decreased significantly with age increasing. The %TBMIL in 16 to 30, 31 to 45 and 46 to 65 year-old groups were 32.3±7.5%, 28.4±8.4% ( P<005 compared with 16 to 30 year-old group) and 25.7±8.2% (compared with 16 to 30 year-old group P<0.001), respectively. In the patients with preoperative HbA1c>7%, HbA1c reduction in the three groups at 12 months after operation were 3.20% (compared with 46-65 year-old group P<0.001), 2.64% (compared with 46-65 year-old group P<0.05) and 1.34%, respectively. The proportions of patients with HbA1c < 6.5% were 95.8%, 88.9% and 50.0%, respectively. LDL, triglyceride and arterial blood pressure in all groups decreased and HDL increased rapidly within 3 months after operation, but there was no significant difference among the three groups. Conclusions:The improvement of blood glucose metabolism and the remission rate of type 2 diabetes mellitus (T2DM) in the patients with older age were worse than those in the younger patients, and the T2DM in the younger patients tends to obtain better clinical remission after LSG; in terms of weight loss, with the increase of age, %TWL and %TBMIL also showed a decreasing trend; however, the improvement of blood lipid and blood pressure after LSG was not affected by the factor of age. This study implies that patients who meet the indications of metabolic and bariatric surgery should be suggested to receive surgical treatment early in order to achieve better clinical outcomes.
