BACKGROUNDParkinson's disease (PD) is a complicated disease, commonly diagnosed among the elderly, which leads to degeneration of the central nervous system. It presently lacks an effective therapy for its complex pathogenesis. Adverse effects from Western drug-based medical intervention prevent long-term adherence to these therapies in many patients. Traditional Chinese medicine (TCM) has long been used to improve the treatment of PD by alleviating the toxic and adverse effects of Western drug-based intervention. Therefore, the aim of this study is to evaluate the efficacy and safety of Xifeng Dingchan Pill (XFDCP), a compound traditional Chinese herbal medicine, taken in conjunction with Western medicine in the treatment of PD patients at different stages in the progression of the disease.

METHODS AND DESIGNThis is a multicenter, randomized controlled trial. In total, 320 patients with early- (n = 160) and middle-stage PD (n = 160) will be enrolled and divided evenly into control and trial groups. Of the 160 patients with early-stage PD, the trial group (n = 80) will be given XFDCP, and the control group (n = 80) will be given Madopar. Of the 160 patients with middle-stage PD, the trial group (n = 80) will be given XFDCP combined with Madopar and Piribedil, and the control group (n = 80) will be given Madopar and Piribedil. The Unified Parkinson's Disease Rating Scale scores, TCM symptoms scores, quality of life, change of Madopar's dosage and the toxic and adverse effects of Madopar will be observed during a 3-month treatment period and through a further 6-month follow-up period.

DISCUSSIONIt is hypothesized that XFDCP, combined with Madopar and Piribedil, will have beneficial effects on patients with PD. The results of this study will provide evidence for developing a comprehensive therapy regimen, which can delay the progress of the disease and improve the quality of life for PD patients in different stages.

TRIAL REGISTRATIONThis trial has been registered in the Chinese Clinical Trial Registry with the identifer ChiCTR-TRC-12002150.

OBJECTIVETo explore the effect of serum restriction on the invasiveness and expressions of insulin-like growth factor-1 (IGF-1) and matrix metalloproteinase-2 (MMP-2) in human trophoblast HTR-8/SVneo cells in vitro.

METHODSHTR-8/SVneo cells were cultured in the presence of 1%, 5%, or 10% fetal bovine serum (FBS) for 48 h. Fluorescence quantitative PCR and immunofluorescence staining were employed to examine the changes in IGF-1 and MMP-2 expressions at both the mRNA and protein levels in HTR-8/SVneo cells; MTT assay and Transwell invasion assay were used to assess the changes of the cell proliferation and the cell invasion ability, respectively. MMP-2 expression, cell proliferation and invasiveness were also assessed in the cells treated with recombinant human IGF-1.

RESULTSHTR-8/SVneo cells exhibited significantly lowered cell proliferation in cultures containing low concentrations of FBS (P<0.05). The expressions of IGF-1 and MMP-2 at both mRNA and protein levels were significantly down-regulated and the invasiveness was significantly lowered in cells cultured in the medium containing 1% FBS as compared with those of cells cultured in the presence of 5% and 10% FBS (P<0.05). Treatment of the cells with recombinant human IGF-1 significantly up-regulated MMP-2 expression (P<0.05) and increased the cell invasiveness (P<0.05).

CONCLUSIONSFBS restriction down-regulates IGF-1 expression in human trophoblast HTR-8/SVneo cells and suppress the cell invasiveness possibly by suppressing MMP-2 expression. Treatment with recombinant human IGF-1 can up-regulate MMP-2 expression and promote the invasiveness of HTR-8/SVneo cells.

This study was purposed to investigate the proliferation, differentiation and apoptosis of human promyelocytic leukemia HL-60 cells induced by proanthocyanidin (PAC). HL-60 cells were incubated with 20 mg/L PAC for 24 h, the cell growth was evaluated by CCK-8 assay. the effect of PAC on HL-60 cells was evaluated and the cells morphology was observed by optical microscopy. Expression of CD14 and CD11b, and cell cycle were analyzed by flow cytometry. The results showed that the growth of HL-60 cells was inhibited after treatment with PAC of different concentration in a dose-dependent manner (P < 0.05). 20 mg/L PAC displayed significant effect on HL-60 cells with inhibition ratio (72.3 ± 1.8)% for 24 h. Microscopy displayed that some cells differentiated to relative mature cells after treating for 48 h. Expression of CD14 increased and the expression of CD11b increased a little after treating with 20 mg/L PAC for 24 h, the ratio of cells in G0/G1 phase increased, but the ratio of cells in S phase decreased. The mRNA and protein expression of P21 gene increased, but the protein expression of CDK4 and Cyclin D1 decreased. It is concluded that PAC may inhibit the proliferation of HL-60 cells in vitro, induces the differentiation of HL-60 cells, and arrests the cells in G0/G1 phase. The possible mechanism may be related to up-regulation of P21 gene expression and down-regulation of the protein expression of CDK4 and Cyclin D1.

Objective To evaluate clinical efficacy and safety of domestic and imported bromfenac sodium eye drops in the treatment of posto-perative inflammation of cataract.Methods A total of 134 cataract patients were divided into treatment group (n =66) and control group (n =68).Control group was treated with imported bromfenac sodium eye drops,and treatment group was given domestic bromfenac sodium eye drops,1 drop in morning and evening respectively.All patients were treated for 14 d.The clinical efficacy and adverse drug reactions in two groups were compared.Results After treatment,the cured rate and effective rate in treatment group were 53.97％ (34/63 cases),46.03％ (29/63 cases).The cured rate and effective rate in control group were 67.74％ (42/62 cases),32.26％ (20/62 cases).There was no significant difference between two groups (P ＞ 0.05).There were no statistical differences between the two groups in ocular tolerance,burning sensation,ophthalmic itching and corneal epithelium spotting at 3,7,14 d after treatment (P ＞ 0.05).There were 1 case of eye discomfort,2 cases of liver function abnormal and 2 cases of urine leukocyteabnormalin control group,with the incidence rate of 7.35％ (5/68 cases).There were 1 case of infection in urinary system,1 case of dizziness,1 case of pathogenesis of primary acute angle-closure glaucoma in right eye,1 case of floating cells in anterior chamber,with the incidence rate of 6.06％ (4/66 cases,P ＞0.05).Conclusion The clinical efficacy of domestic bromfenac sodium eye drops in the treatment of cataract patients is comparable to imported bromfenac sodium eye drops.The clinical efficacy is exactly,with lower adverse drug reactions and price.

OBJECTIVETo elucidate the mechanisms of up regulated expression of cytoplasmic phospholipase A2 (CPLA2) induced by one lung ventilation (OLV) by investigating the interactions between nuclear factor kappaB (NF-κB) and C-PLA2.

METHODSForty-eight healthy Japanese white rabbits were randomized into control group, solvent treatment group (group S), NF-κB inhibitor (PDTC)/solvent treatment group ( group PS), C-PLA2 inhibitor (AACOCF3)/solvent treatment group (group AS), OLV group (group O), solvent treatment plus OLV group (SO group), NFκB inhibitor (PDTC)/solvent treatment plus OLV group (group PSO) and CPLA2 inhibitor (AACOCF3)/solvent treatment plus OLV group (group ASO). ELISA was used to detect arachidonic acid (AA) content in the lung tissues, and NFκB and CPLA2 expressions were detected by Western blotting and quantitative PCR. Lung injuries were assessed based on the lung histological score, and the polymorphonuclear leukocyte count in the bronchial alveolar lavage fluid, myeloperoxidase (MPO) content in the lung tissues, and lung wet/dry weight (W/D) raito were determined.

RESULTSTreatment of the rabbits with the solvent did not produce any adverse effects. OLV caused obvious lung injury in the rabbits and up regulated the expressions of CPLA2 and NFκB in the lung tissues (P<0.05). In rabbits without OLV, treatment with AACOCF3 or PDTC significantly down regulated both CPLA2 and NFκB expressions without affecting the other parameters. In rabbits with OLV, treatment with AACOCF3 or PDTC obviously lowered CPLA2 and NFκB expressions and lessened the OLV-induced lung injuries.

CONCLUSIONBoth C-PLA2 and NF-κB play important roles and show interactions in OLV-induced lung injury in rabbits.

Objective To analyze the endemic status of schistosomiasis in Suzhou City from 2010 to 2020, so as to provide the evidence for formulating the future schistosomiasis control strategy. Methods The data pertaining to the endemic status of schistosomiasis in Suzhou City from 2010 to 2020 were retrieved from the annual schistosomiasis control report, the information management platform of schistosomiasis (parasitic diseases) in Jiangsu Province and the Parasitic Diseases Control Information Management System of Chinese Center for Disease Control and Prevention, including snail survey data, snail control data and schistosomiasis examination data, and were retrospectively reviewed. Differences of proportions were tested for statistical significance with chi-square test, and the trends in proportions were evaluated using the chi-square test for trends. Results Elimination of schistosomiasis was achieved in Suzhou City in 2018, and there were 3.528 9 million residents living in schistosomiasis-endemic villages of 81 townships in 9 counties. A total of 707 600 labor-days were used for snail survey in 11 586 village-times in Suzhou City from 2010 to 2020, covering 18 572.73 hm², and snail habitats were detected with an area of 68.61 hm², including emerging snail habitats of 37.30 hm². A total of 23 144 snails were dissected, and no Schistosoma japonicum infection was detected. Reemerging and emerging snail habitats were predominantly found in inlands. During the period from 2010 to 2020, snail control was performed in Suzhou City for 71 000 labor-times, and snail control was done covering 269.34 hm² through chemical treatment and covering 3.48 hm² through environmental improvements. A total of 674 002 person-times received serological tests for S. japonicum infections in Suzhou City from 2010 to 2020, with seroprevalence of 0.38%, and a total of 33 835 person-times received stool examinations, with no egg-positives identified. The sero-prevalence of S. japonicum infections appeared an overall tendency towards a rise in Suzhou City from 2010 to 2020 (χ² = 129.48, P < 0.001). The sero-prevalence of S. japonicum infections appeared high among local residents in 2016, and remained stable in other years, while the sero-prevalence of S. japonicum infections appeared an overall tendency towards a rise among mobile populations (χ² = 54.11, P < 0.001). There were 278 800 and 175 202 serological tests among local residents and mobile populations in Suzhou City from 2013 to 2020, and 0.50% and 0.35% sero-prevalence rates were detected, respectively. The sero-prevalence of S. japonicum infections was significantly higher among local residents than among mobile populations in Suzhou City (χ²= 54.76, P < 0.001). Conclusions There is a risk of rebound of schistosomiasis in Suzhou City. Integrated control should be reinforced to prevent the risk of rebound of schistosomiasis in Suzhou City.

Objective To compare the diagnostic efficacy of 3 lung ultrasound criteria in evaluating cardiogenic pulmonary edema,so as to obtain the optimal diagnostic criterion and to provide effective auxiliary measure for the rapid diagnosis of cardiogenic pulmonary edema.Methods A total of 98 patients who underwent lung ultrasound in the Shanghai Chest Hospital from June 2022 to November 2022 were included.Three positive criteria were defined according to the number and distribution of positive points based on the pleural and B lines:criterion 1 was set as at least 2 positive points;criterion 2 was set as at least 3 positive points;criterion 3 was set as at least 1 positive point on each side.The efficacies of 3 criteria in diagnosis of cardiogenic pulmonary edema,and their consistencies with clinical diagnosis were compared.Results The sensitivities of criterion 1,criterion 2,and criterion 3 were 88%,72%and 79%,the specificities was 89%,100%and 93%,the accuracies was 87%,88%and 87%,respectively.The criteri on 2 showed a higher consistency in the diagnosis of cardiogenic pulmonary edema with clinical diagnosis(Kappa value=0.877);the criterion 1 and criterion 3 were generally consistent in the diagnosis of cardiogenic pulmonary edema with clinical diagnosis(Kappa values were 0.783 and 0.727,respectively).Conclusions The diagnostic efficacies of the 3 positive lung ultrasound criteria for cardiogenic pulmonary edema are high,and"at least 3 positive points"is more helpful for clinical diagnosis.

Objective To investigate the technique of the suprameatal approach for cochlear implantation in Chinese profound sensory heating loss children.Methods Suprameatal approach for cochlear implantation were used in 50 cases(total 53 ears)with profound sensory hearing loss from May 2005 to January 2007.The electrode was passed through the suprameatal tunnel and went between the incus and chorda tympani into the scala tympani.Results Electrodes were completely inserted in 51 ears.There were no postoperative complications in all cases.Although the long effect need to be observed,all cases received better heating and speech development benefit from cochlear implantation in the follow-up period.Among the 50 cases,26 had speech perception in the open condition;18 patients could speak short sentences although not clearly;and 6 patients learned to speak individual words only.Conclusions The suprameatal approach was found to be a simple and safe technique that does not need mastoidectomy and avoid endangeting the facial nerve and the chorda tympani.It enables wide exposure of middle ear and is especially suitable for cases with narrow facial recess or anteriorly located facial nerve.
