AlM:To find better ways of treating ocular alkali burn, and to reduce the suffering of patients and social burden.METHODS:Totally 100 patients were graded according to the degree of chemical burns to four major groups, each half were randomly divided into the control group and the treatment group. Control group underwent conventional treatment. ln addition to conventional therapy, patients in each treatment group were also added a Breviscapine intravenous injection of 40mg daily. Corneal recovery time, changes in vision, degree of corneal opacity, number of corneal neovascularization and other complications were observed. Curative effects were analyzed statistically.
RESULTS:There was no significant difference in levelⅠgroup between control group and treatment group ( P>0. 05); There were significantly different in level Ⅱ, Ⅲand Ⅳ group ( P<0. 05 ). Compared to the degree of corneal opacity and the number of corneal neovascularization, the treatment group was obviously better than the control group(P<0. 05).
CONCLUSlON: Breviscapine in the treatment of ocular alkali burns can shorten the course of treatment, reduce corneal scarring, and improve vision.

OBJECTIVETo analyze the correlation between pressure-derived collateral coronary flow (PDCF) and Rentrop grade of patients with acute myocardial infarction (AMI).

METHODSPDCF, determined by the ratio of P(w)/P(a), was measured in 29 patients with AMI of the first onset who received primary percutaneous coronary intervention (PCI) within 12 h after the onset. Sufficient collateral flow (group A, n=19) was defined as PDCF>0.24 and insufficient collateral flow (group B, n=10) as PDCF< or =0.24. Rentrop grade of the collateral flow was evaluated by coronary angiography. Echocardiography was performed on the 3rd and 30th day after PCI. The left ventricular ejection fraction, end-systolic and end-diastolic volumes, and the related indexes were obtained.

RESULTRentrop grade was significantly related to PDCF (r=0.75, P<0.01), but a wide range of PDCF was observed in patients with Rentrop grade< or =1.

CONCLUSIONPDCF measurement allows quantitative evaluation of the collateral flow in patients with AMI.

OBJECTIVETo analyze the survival level and variation of esophageal cancer in Linzhou city of Henan province from 1988 to 2004, and evaluate the effects of diagnosis and treatments on esophageal cancer in this area.

METHODSAll incidence and death records for esophageal cancer during 1988 to 2004 were collected from Linzhou Tumor Registry. Cases with duplicate information or death certificate only were excluded. A total of 12,160 cases of esophageal cancer were collected, of which, 6914 cases were male, and 5246 cases were female. The sex-specific and age-specific probabilities of survival in 1992, 1997 and 2002 were calculated and linked to the data of incidence and death on esophageal cancer in this area. Five-year observed survival rate and five-year relative survival rate during 1990 to 1994, 1995 to 1999, 2000 to 2004 were calculated respectively using period survival analysis and cohort survival analysis and Z test.

RESULTSThe 5-year relative survival rates among the three-episode were 28.24%, 35.24% and 40.76% respectively during 1988 to 2004. This showed an increasing trend by periods (Z values were 3.94 and 3.07, P < 0.05). The 5-year observed survival rates in men among the three-episode were 13.67%, 18.08% and 22.46% respectively, the 5-year relative survival rates were 29.94%, 36.96% and 38.40%. The 5-year observed survival rates in women among the three-episode were 15.56%, 19.29% and 28.01% respectively, the 5-year relative survival rates were 26.78%, 33.12% and 43.70%. During the two former periods, there was no significant difference in the 5-year observed survival rate and relative survival rate between men and women (Z values of observed survival rate were 1.48 and 0.88, P > 0.05. Z values of relative survival rate were 1.27 and 1.50, P > 0.05). In the third period, the 5-year observed survival rate and relative survival rate in women was higher than that in men (observed survival rate Z = 3.56, P < 0.05; relative survival rate Z = 2.09, P < 0.05). The relative survival rate that calculated using period method (respectively 35.24% and 40.76%) was higher than that using cohort method (respectively 28.77% and 33.35%) from 1995 to 1999, and from 2000 to 2004.

CONCLUSIONThe survival rate on esophageal cancer in Linzhou city was increasing in the three different periods. This indicated a rising status in the secondary prevention and clinical diagnosis and treatments on esophageal cancer.

BACKGROUNDThe prevalence of hepatitis B virus (HBV) infection is high among individuals infected with human immunodeficiency virus (HIV) in China. Both HIV and HBV can be treated with tenofovir disoproxil fumarate (TDF) and lamivudine (3TC), so we evaluated the safety and efficacy of combination antiretroviral therapy (ART) that included TDF, 3TC, and efavirenz (EFV) among ART-naive individuals who were co-infected with HIV and HBV.

METHODSOne hundred HIV/HBV co-infected ARV-naive individuals were started on the regimen of TDF, 3TC, and EFV, and the levels of plasma HBV DNA, HIV RNA, and biochemical evaluation related to the function of liver and kidney were analyzed.

RESULTSConcerning efficacy, this study found that by week 48, the vast majority co-infected participants receiving this ART regimen had undetectable HBV DNA levels (71%) and/or HIV RNA levels (90%). Concerning safety, this study found that the median estimated glomerular filtration rate of participants decreased from baseline (109 ml·min-1·1.73 m-2) to week 12 (104 ml·min-1·1.73 m-2) but was almost back to baseline at week 48 (111 ml·min-1·1.73 m-2).

CONCLUSIONThis combination ART regimen is safe and effective for patients with HIV/HBV co-infection.

OBJECTIVETo investigate mechanism of di-(2-ethylhcxyl)phthalate (DEHP) exposure in causing blood-testis barrier (BTB) impairment in rats.

METHODSTwo-months-old male SD rats were randomly divided into corn oil control group and DEHP (750 mg/kg) exposure group for daily intragastic treatment for 30 consecutive days. After the treatments the rats were examined for histomorphological changes of the testicle using HE staining and the expressions of the junction proteins N-cadherin β-catenin, occludin and connexin43 of the BTB using Western blot. In the in vitro study, the vitality and ROS generation level in Sertoli cells exposed to different concentrations of DEHP were examined with MTT and ROS assay kits, respectively, and Nrf2 and p-p38 expressions were detected with Western blot.

RESULTSCompared with the control group, the rats with DEHP exposure showed structural damage of the seminiferous tubule and polarity loss of the spermatids. DEHP exposure caused significantly decreased expressions of occludin and connexin43 but increased expressions of N-cadherin and β-catenin in the testicle tissues of the rats (P<0.05). The vitality of Sertoli cells was obviously decreased and ROS level increased significantly after exposure of the cells to increasing concentrations of DEHP, which also resulted in significantly up-regulated Nrf2 and p-p38 expressions (P<0.05).

CONCLUSIONSDEHP exposure causes increased oxidative stress in the Sertoli cells of the testis, activates p38 MAPK signaling pathway, and results eventually in impaired spermatogenesis in rats.

OBJECTIVETo investigate the effects of miR-21 on paclitaxel-resistance in human breast cancer MCF-7/PR and SKBR-3/PR cells.

METHODSPaclitaxel-resistant human breast cancer cell lines MCF-7/PR and SKBR-3/PR were established by stepwise selection in increasing concentration of paclitaxel. Cellular morphology, mRNA and protein level of MDR1, BCRP and MRP1 in MCF-7/PR and SKBR-3/PR cells were determined. The expression of Bax, Bcl-2 and miR-21 in parental and paclitaxel-resistant cells was detected by RT-PCR and Western blotting. The synthetic miR-21 inhibitor or miR-21 mimic were transfected into MCF-7/PR, SKBR-3/PR and MCF-7, SKBR-3 cells with Lipofectamine 2000. The miR-21 levels were determined by RT-PCR, and P-gp, Bcl-2 and Bax protein levels were examined by Western blotting. MTT assay was used to measure the cell viability, and flow cytometry was performed to analyze the cell cycle and apoptosis.

RESULTSThe levels of MDR1, BCRP, MRP1, Bcl-2/Bax and miR-21 in MCF-7/PR and SKBR-3/PR cells were significantly higher than those in MCF-7 and SKBR-3 cells. The protein levels of P-gp, Bcl-2 were up-regulated, and Bax was down-regulated compared with parental cells. MiR-21 was significantly down-regulated after miR-21 inhibitor was transfected; and the levels of MDR1, BCRP, MRP1 and Bcl-2/Bax (P <0.05) were also down-regulated. MiR-21 inhibitors significantly suppressed G0/G1 transition of the cell cycle, and induced cell apoptosis in MCF-7/PR and SKBR-3/PR cells. MTT results showed that miR-21 inhibitors induced sensitivity of MCF-7/PR and SKBR-3/PR cells to paclitaxel. And miR-21 mimic can increase the expression of MDR1, Bcl-2/Bax and change cell morphology from parental cells to resistant cells.

RESULTSThe established MCF-7/PR and SKBR-3/PR breast cancer cells show typical multidrug resistance characteristics, which can be used as the model for drug resistance study. Down-regulated miR-21 expression in MCF-7/PR and SKBR-3/PR breast cancer cells can enhance cell sensitivity to paclitaxel.

Aim To investigate the curative effects of resveratrol on OVA induced allergic rhinitis in mice and the underlying immune mechanisms. Methods Balb/c mice (female, 6 weeks) were divided randomly into normal control ( NC) group, allergic rhinitis (AR) group, high dose resveratrol treatment group (RH), low dose resveratrol treatment group (RL), and dexamethasone treatment group ( Dex). RL, RH and Dex group were oral administered with resveratrol 30 mg • kg"1, resveratrol 100 mg • kg"1 and dexamethasone 10 mg • kg"1, respectively. After the treat-ment , the sneezing and nasal rubbing behaviors of mice in all the group were recorded and HE was performed to assess the inflammatory cell infiltration in nasal tissues. The sera levels of allergic cytokines were determined with ELISA assay. The percentage of CD4+ GA- TA3 + T cells in spleen of each group was further recorded by flow cytometry. Results Compared with AR group, treatment with resveratrol (100 mg - kg"1) reduced the sneezing and nasal rubbing behaviors signifi-cantly and improved inflammatory cell infiltration in nasal tissues. The up-regulated sera levels of IL-4, IL- 13 and OVA-sIgE in AR group were reversed by RH, and ratios CD4+ GATA3 + Th2 cells in spleen of RH were also down-regulated parallelly. Conclusions RH treatment could improve the allergic related symptoms of OVA-induced allergic rhinitis, which is associated with down-regulated sera levels of IL-4, IL-13 and OVA-sIgE and ratios of CD4+ GATA3 + Th2 cells in spleen of mouse model.

OBJECTIVE: The study explores the effects of electroacupuncture (EA) at the governing vessel (GV) on proteomic changes in the hippocampus of rats with cognitive impairment. METHODS: Healthy male rats were randomly divided into 3 groups: sham, model and EA. Cognitive impairment was induced by left middle cerebral artery occlusion in the model and EA groups. Rats in the EA group were treated with EA at Shenting (GV24) and Baihui (GV20) for 7 d. Neurological deficit was scored using the Longa scale, the learning and memory ability was detected using the Morris water maze (MWM) test, and the proteomic profiling in the hippocampus was analyzed using protein-labeling technology based on the isobaric tag for relative and absolute quantitation (iTRAQ). The Western blot (WB) analysis was used to detect the proteins and validate the results of iTRAQ. RESULTS: Compared with the model group, the neurological deficit score was significantly reduced, and the escape latency in the MWM test was significantly shortened, while the number of platform crossings increased in the EA group. A total of 2872 proteins were identified by iTRAQ. Differentially expressed proteins (DEPs) were identified between different groups: 92 proteins were upregulated and 103 were downregulated in the model group compared with the sham group, while 142 proteins were upregulated and 126 were downregulated in the EA group compared with the model group. Most of the DEPs were involved in oxidative phosphorylation, glycolipid metabolism and synaptic transmission. Furthermore, we also verified 4 DEPs using WB technology. Although the WB results were not exactly the same as the iTRAQ results, the expression trends of the DEPs were consistent. The upregulation of heat-shock protein β1 (Hspb1) was the highest in the EA group compared to the model group. CONCLUSION EA can effect proteomic changes in the hippocampus of rats with cognitive impairment. Hspb1 may be involved in the molecular mechanism by which acupuncture improves cognitive impairment.

Objective: To analyze the clinical epidemiological characteristics including composition of pathogens , clinical characteristics, and disease prognosis acute bacterial meningitis (ABM) in Chinese children. Methods: A retrospective analysis was performed on the clinical and laboratory data of 1 610 children <15 years of age with ABM in 33 tertiary hospitals in China from January 2019 to December 2020. Patients were divided into different groups according to age,<28 days group, 28 days to <3 months group, 3 months to <1 year group, 1-<5 years of age group, 5-<15 years of age group; etiology confirmed group and clinically diagnosed group according to etiology diagnosis. Non-numeric variables were analyzed with the Chi-square test or Fisher's exact test, while non-normal distrituction numeric variables were compared with nonparametric test. Results: Among 1 610 children with ABM, 955 were male and 650 were female (5 cases were not provided with gender information), and the age of onset was 1.5 (0.5, 5.5) months. There were 588 cases age from <28 days, 462 cases age from 28 days to <3 months, 302 cases age from 3 months to <1 year of age group, 156 cases in the 1-<5 years of age and 101 cases in the 5-<15 years of age. The detection rates were 38.8% (95/245) and 31.5% (70/222) of Escherichia coli and 27.8% (68/245) and 35.1% (78/222) of Streptococcus agalactiae in infants younger than 28 days of age and 28 days to 3 months of age; the detection rates of Streptococcus pneumonia, Escherichia coli, and Streptococcus agalactiae were 34.3% (61/178), 14.0% (25/178) and 13.5% (24/178) in the 3 months of age to <1 year of age group; the dominant pathogens were Streptococcus pneumoniae and the detection rate were 67.9% (74/109) and 44.4% (16/36) in the 1-<5 years of age and 5-<15 years of age . There were 9.7% (19/195) strains of Escherichia coli producing ultra-broad-spectrum β-lactamases. The positive rates of cerebrospinal fluid (CSF) culture and blood culture were 32.2% (515/1 598) and 25.0% (400/1 598), while 38.2% (126/330)and 25.3% (21/83) in CSF metagenomics next generation sequencing and Streptococcus pneumoniae antigen detection. There were 4.3% (32/790) cases of which CSF white blood cell counts were normal in etiology confirmed group. Among 1 610 children with ABM, main intracranial imaging complications were subdural effusion and (or) empyema in 349 cases (21.7%), hydrocephalus in 233 cases (14.5%), brain abscess in 178 cases (11.1%), and other cerebrovascular diseases, including encephalomalacia, cerebral infarction, and encephalatrophy, in 174 cases (10.8%). Among the 166 cases (10.3%) with unfavorable outcome, 32 cases (2.0%) died among whom 24 cases died before 1 year of age, and 37 cases (2.3%) had recurrence among whom 25 cases had recurrence within 3 weeks. The incidences of subdural effusion and (or) empyema, brain abscess and ependymitis in the etiology confirmed group were significantly higher than those in the clinically diagnosed group (26.2% (207/790) vs. 17.3% (142/820), 13.0% (103/790) vs. 9.1% (75/820), 4.6% (36/790) vs. 2.7% (22/820), χ²=18.71, 6.20, 4.07, all P<0.05), but there was no significant difference in the unfavorable outcomes, mortility, and recurrence between these 2 groups (all P>0.05). Conclusions: The onset age of ABM in children is usually within 1 year of age, especially <3 months. The common pathogens in infants <3 months of age are Escherichia coli and Streptococcus agalactiae, and the dominant pathogen in infant ≥3 months is Streptococcus pneumoniae. Subdural effusion and (or) empyema and hydrocephalus are common complications. ABM should not be excluded even if CSF white blood cell counts is within normal range. Standardized bacteriological examination should be paid more attention to increase the pathogenic detection rate. Non-culture CSF detection methods may facilitate the pathogenic diagnosis.
