ABSTRACT
AIM: To investigate the clinical efficacy and safety of ultrasonic ciliary plasty(UCP)combined with injection of anti-vascular endothelial growth factor(VEGF)in the treatment of neovascular glaucoma(NVG).METHODS: A total of 30 NVG patients(30 eyes)admitted to the First Affiliated Hospital of Bengbu Medical College from September 2020 to September 2021 were selected. After admission, all the eyes of the patients were injected with anti-VEGF drug(ranibizumab). After surgery, 15 patients were randomly selected for UCP treatment(UCP group), and the other 15 patients received trabeculectomy(trabeculectomy group). During the 10mo postoperative follow-up, the decrease of intraocular pressure was compared between the two groups and the changes of the degree of ocular pain and the occurrence of related complications were evaluated at each follow-up visit.RESULTS: The intraocular pressure and pain degree of the UCP and trabeculectomy groups were significantly lower than those before operation, and the complication probability of the UCP group was less than that of the trabeculectomy group.CONCLUSION: With fewer complications and high safety, UCP combined with anti-VEGF injection can effectively control intraocular pressure and pain in NVG patients.
ABSTRACT
Objective To investigate chromosome abnormality rate and related factors of spontaneous abortion in early pregnancy. Methods A total of 831 tissue samples of spontaneous abortion in early pregnancy were collected from June 2015 to August 2018 in the First Affiliated Hospital of Nanjing Medical University. Chromosomal copy number was analyzed by next generation sequencing (NGS). The relationships between chromosome abnormality and maternal age, in vitro fertilization?embryo transfer (IVF?ET) pregnancy, number of previous spontaneous abortions, history of live birth were analyzed by statistical methods. Results Among 831 tissue samples of spontaneous abortion in early pregnancy, 461 (55.5%, 461/831) were found to have chromosome abnormalities. Maternal age (OR=1.107, 95%CI: 1.070-1.145) and history of live birth ( OR=1.909, 95%CI : 1.182-3.083) were the positive correlative factors of chromosome abnormality. Times of previous spontaneous abortion (OR=0.807, 95%CI: 0.702-0.928) and IVF?ET pregnancy ( OR=0.554, 95%CI : 0.404-0.760) were the negative correlative factors of chromosome abnormality. Conclusions Chromosome abnormality is an important cause of spontaneous abortion in early pregnancy. The rate of chromosome abnormality increases with the increase of maternal age and the history of live birth, and decreases with the increase of number of previous spontaneous abortion and IVF?ET pregnancy.

Objective To investigate the characteristics of bone marrow examination in systemic lupus erythematosus (SLE) patients with blood system damage.Methods The data of 150 SLE patients with bone marrow puncture were analyzed retrospectively.Results Of the 150 patients,68 patients had abnormalities in bone marrow examination.Common bone marrow abnormalities were low proliferative bone marrow (26 cases,38.2％),hemophagocytic (17 cases,25％),pure red blood cells aplastic anemia (6 cases,8.8％),aplastic anemia (12 cases,17.6％) and decreased megakaryocyte count (7 cases,10.4％).10 cases of severe and severe anemia (90.9％ of patients with severe and severe anemia) and 21 patients with severe thrombocytopenia (67.7％ of patients with severe thrombocytopenia) had abnormal bone marrow examination.Conclusions It is not uncommon for SLE patients to have abnormal bone marrow examination.When the peripheral blood test is found to be severe anemia or severe thrombocytopenia,bone marrow aspiration and bone marrow biopsy are needed.
ABSTRACT
Primary ciliary dyskinesia (PCD) is an autosomal recessive or X-linked inherited disorder.The diagnosis of PCD is primarily based on clinical assessment accompanied with various supplementary methods,such as nasal nitric oxide (NO) examination,high-speed video microscopy,transmission electron microscopy and genetic tests.Some patients may fail to have a timely diagnosis resulted in delayed treatment since the devices and expertise limited in most medical centers.Recently,the use of immunofluorescence (IF) in PCD diagnosis is gaining acceptance within the clinical community.Specific antibodies against ciliary architecture are used in IF analyses to elucidate ciliary abnormality and are potentially important for early diagnosis of PCD.The present review summarizes the diagnostic methods of PCD with a focus on IF.
ABSTRACT
BACKGROUND:Caffeic acid phenethyl ester (CAPE) can inhibit lipid peroxidation after rat brain injury. However, the trend of 5-lipoxygenaseis (5-LOX) and cysteinyl leukotrienes (CysLTs) in model of Parkinson’s disease, and whether CAPE protects against rotenone-induced cel ular injuries by inhibiting the levels of 5-LOX and CysLTs stil need further research. OBJECTIVE:To investigate the protective effect of CAPE on the rotenone-induced Parkinson-like injury, and to determine whether 5-LOX involved. METHODS:(1) PC12 cel s in good-growth were col ected and divided into five groups cultured with different concentrations of rotenone (0, 0.01, 0.1, 1, 10μmol/L). 24 and 48 hours later, changes of cel ular morphology and activity were observed to single out the optimum concentration of rotenone;at 24 hours, the levels of 5-LOX and CysLTs were detected by western blotting and ELISA, respectively. (2) PC12 cel s were pretreated with different concentrations of CAPE (0, 0.01, 0.1, 1, 10 μmol/L) for 30 minutes, and 1 μmol/L rotenone was then added. The other cel s received no intervention as blank control group. Subsequently, the cel activity was detected, and the CysLTs production was detected by ELISA at 24 hours. RESULTS AND CONCLUSION:(1) Rotenone (0.1-10μmol/L) could induce PC12 cel injury with overt morphological and cel activity changes at 24 hours, especial y the 1 μmol/L rotenone. (2) Rotenone also significantly increased the 5-LOX expression and CysLTs production in a concentration-dependant manner. (3) CAPE (1-10μmo/L) significantly attenuated rotenone-induced CysLTs production and cel viability reduction in a concentration-dependant manner. (4) These results suggest that CAPE protects against PC12 cel injuries in the model rat with Parkinson’s disease induced by rotenone involving 5-Lox.
ABSTRACT
Objective To evaluate the efficacy of etanercept in active ankylosing spondylitis (AS) pa-tient for 48 weeks by tapering the dosage of etanercept every 12 weeks. Methods 52 patients with active AS were enrolled in this study , and 47 patients finished 48 Weeks of observation. 50 mg etanercept was applied subcutaneously once a week for 12 weeks , and was tapered to 50 mg every two weeks for another 12 weeks , and then 25 mg every two weeks for another 24 weeks. BASDAI, BASFI, BASMI, ASDAS, as well as Serum levels of CRP and ESR were doaunented at week 0, 12, 24 and 48, respectively. Result Among the 47 active AS patients, 40 (85.1%) were male, with mean disease duration of 4.1 ± 3.8 years. After 12 -week treatment with 50 mg etanercept weekly, the scores of BASDAI, BASFI, BASMI, ASDAS, as well as levels of ESR and CRP, declined significantly compared to the baseline (P < 0.05, respectively). Despite of tapering the dosage of etan-ercept gradually, most of the patients (87.2%, 41/47) kept in ASAS 40 response during the following 36 weeks. No severe adverse events were observed during the treatment period. Conclusion This study demonstrat-ed the clinical efficacy of etanercept in patients with active AS. A dosage reduction strategy could maintain the clinical efficacy of etanercept during 48 weeks , which indicates that gradually tapering etanercept might be a po-tential effective, economic and safe way for active AS patients.
ABSTRACT
Objective To understand the status of breastfeeding and to explore the influencing factors among infants within six months of age in Yongkang City.Methods A total of 667 infants aged 0 -6 months from 9 towns in Yongkang City was selected by random cluster sampling method and their mothers were interviewed by self -designed questionnaire .Results By 7 days,1 month,3 months and 4 -6 months,the rate of pure breastfeeding was 69.72%,77.66%,58.32% and 27.97% respectively;the rate of almost pure breastfeeding was 1.95%,0.45%,0.60% and 1.69% respectively;the rate of partial breastfeeding was 13.34%,14.39%,30.13% and 47.46% respectively;the rate of artificial feeding was 14.99%,7.50%,10.95% and 22.88% respectively.There were statistical differences on the rates of breastfeeding among four groups(P <0.05).Non -conditional logistic regression analysis showed that mother's age below 30 (OR =0.464,95%CI =0.315 -0.682),low education level (OR =0.507,95%CI =0.305 -0.842)and part -time working (OR =0.517,95%CI =0.352 -0.758)were protective factors of breastfeeding.Family income above 6 000 yuan was the risk factor of breastfeeding (OR =1.923,95%CI =1.306 -2.833).Conclusion The rate of breastfeeding for infants within six month of age was high,but the rate of breastfeeding by 4 -6 months dropped sharply.The mothers aged below 30 with the family income above 6 000 yuan,with full -time job and higher education level have low breastfeeding rate relatively.
ABSTRACT
[Objective] To investigate the purchase and use of edible oil , as well as recycling of kitchen waste oil in Shanghai catering service units , providing reference for relevant regulatory authorities . <br> [ Methods] A total of 976 units of various types of catering service in Shanghai were selected via strati-fied sampling methodology , a self-designed questionnaire used to investigate the purchase and use of edi-ble oil, as well as recycling of kitchen waste oil .Meanwhile, an on-site rapid detection technology was used to test items including acid value , peroxide value , polar components of unused pre -packaged edible oil and also the process of using frying oils on site . [ Results] The amount of edible oil used in catering service units of Shanghai was about 1235 tons per day;6.0% of the oil purchased was bulk cooking oil , which accounted for 5 .6%of the total amount consumed;44 .3%of the catering service units signed with professional companies for the recycling of kitchen waste oil;3615 samples were detected using an on -site rapid detection , of which 17 were suspected to be positive .The lab confirmed that test results were quali-fied. [ Conclusion] The edible oil used in Shanghai catering service units is safe in general , while bulk cooking oil may have potential safety hazards .Food practitioners have low awareness of health risk caused <br> by using edible oil repeatedly and for too long time , which makes some enterprise use “old oil” for too long;There does exist the possibility of kitchen waste oil returning to food chain as its recycling has not been standardized .
ABSTRACT
<p><b>OBJECTIVE</b>To establish a method to test citrinin (CIT) in monascus products by immuno-affinity chromatography (IAC)-high performance liquid chromatography (HPLC), and to detect the content of CIT in monascus products in Fujian province.</p><p><b>METHODS</b>IAC-HPLC was applied to detect the CIT content in monascus products. The conditions to use HPLC were as follows: C(18) reversed-phase chromatographic column, 150.0 mm×4.6mm×3 µm; mobile phase: the volume ratio of acetonitrile and 0.1% phosphoric acid solution at 65:35; isocratic elution; column temperature: 28°C; flow velocity: 0.8 ml/min; fluorescence detector, excitation wavelength (λ(ex)) was 331 nm and emission wavelength (λ(em)) was 500 nm. The standard curved was established by the linear regression of peak area (Y) to CIT content (X, ng/ml). The accuracy and precision of the method would then be verified. And 32 kinds of monascus products were determined and their color values were compared by this method.</p><p><b>RESULT</b>The standard curve established in this study was Y = 4634.8X-136.42, r = 1.000; whose limits of detection was 20 µg/kg and the limits of qualification was 64 µg/kg.

<p><b>BACKGROUND</b>Treponema pallidum (T. pallidum) subsp. pallidum is the causative agent of syphilis. Analysis of recombinant antigens of T. pallidum led to the identification of potential candidate antigens for vaccine development and syphilis serodiagnosis. Tp0965 was predicted to be a membrane fusion protein and was found to be reactive with infected human sera in previous studies, but the results were controversial. In this research, the antigenicity and immunoreactivity of recombinant protein Tp0965 were assessed.</p><p><b>METHODS</b>T. pallidum subsp. pallidum (Nichols strain) was propagated and isolated and the genomic DNA was extracted. The Tp0965 gene was amplified by polymerase chain reaction (PCR). Then the recombinant protein Tp0965 was expressed in Escherichia coli and purified by nickel-nitrilotriacetic acid (Ni-NTA) purification system. The reactivities of protein Tp0965 were examined by immunoblot analysis and indirect enzyme-linked immunosorbent assay. The antisera against protein Tp0965 were obtained by immune rabbits and the immunogenicity of antisera were detected by indirect enzyme-linked immunosorbent assay.</p><p><b>RESULTS</b>Recombinant protein Tp0965 was expressed successfully in vitro. Immunoblot assay showed that the recombinant protein Tp0965 could be recognized by human syphilitic sera of all stages. Indirect enzyme-linked immunosorbent assay showed there were only 4 of 74 human syphilitic sera that failed to show reactivity to recombinant antigen Tp0965, and lack of reactivity of Tp0965 to all 28 uninfected sera. A low titer of antiserum against Tp0965 in immune rabbits could be detected after the third time of immunization.</p><p><b>CONCLUSIONS</b>The recombinant antigen Tp0965 shows excellent sensitivity for the reactivity with sera from syphilitic individuals at all stages. The results also demonstrate a potential application for the serodiagnosis of syphilis.</p>

<p><b>BACKGROUND</b>The management of atypical squamous cells of undetermined significance/low-grade squamous intraepithelial lesions (ASCUS/LSIL) is still controversial and it is advisable to make a triage for these two cytological abnormalities. P16(INK4) (P16) has been shown to be a potential biomarker for predicting high-grade cervical intraepithelial neoplasia (CIN) and cervical cancer. The aim of the study was to determine the value of P16 expression by immunostaining method compared with high-risk human papillomavirus (HR-HPV) DNA test in the triage of ASCUS/LSIL women.</p><p><b>METHODS</b>Totally 86 eligible residual liquid-based cytological specimens with ASCUS and 45 with LSIL were obtained. All specimens were submitted to HR-HPV DNA test (HC2) and P16 immunocytochemical staining simultaneously. And all women underwent colposcopy and biopsy after cytology.</p><p><b>RESULTS</b>The positive rate of P16 staining was 32.6% in ASCUS and 42.2% in LSIL, which was significantly lower than that of HR-HPV test in both ASCUS (P < 0.05) and LSIL (P < 0.05). Moreover, the positive rate of P16 staining was 12.7% in normal histology, 61.5% in CIN 1, 87.0% in CIN 2-3, and 100.0% in cancer, in which P16 positive rate was significantly lower than HR-HPV positive rate in normal group. The sensitivity, specificity, positive predictive value (PPV), negative predictive value (NPV) and accuracy of P16 staining for predicting CIN 2 or more were 87.5%, 68.6%, 38.9%, 96.0%, and 72.1%, respectively in the ASCUS; while 90.0%, 71.4%, 47.4%, 96.2% and 54.7%, respectively in the LSIL, in which the specificity and accuracy of P16 staining were significantly higher than those of HR-HPV test in both ASCUS and LSIL (P < 0.05).</p><p><b>CONCLUSION</b>P16 immunostaining had significantly higher specificity and accuracy than HR-HPV DNA test for predicting for high-grade CIN and cervical cancer in ASCUS and LSIL and can be used for the triage of women with ASCUS/LSIL cytological abnormality.</p>

Objective To explore the relationship between Adult-onset Still's disease (AOSD) and macrophage activation syndrome (MAS). Methods A total of 78 patients with AOSD who had completed medical information were included in this study. Eleven patients who were diagnosed as rheumatic disease associated hemophagocytic syndrome among 26 patients who had hemophagocytic syndrome with histological evidence consisted of the MAS group. Clinical and laboratory data were analyzed in 78 patients with AOSD and 11 patients with MAS. Results Among 78 cases of AOSD, 9 patients (12%) could be diagnosed as MAS but didn't have hemophagocytic histological evidence. In the 11 MAS cases with hemophagocytic phenomenon, 6 patients fulfilled the diagnostic criteria of AOSD, 2 cases with panniculitis, 1 case with SLE, 1 case of dermatomyositis and 1 case of systemic vasculitis. Logistic analysis showed that splenomegaly (OR =2.13, 95%CI=1.11-3.42), leukopenia (OR=3.57, 95%CI=2.30～4.86), anaemia (OR=0.85, 95%CI=1.03～2.76), thrombocytopenia (OR=2.98, 95%CI=1.17-4.30) and hypertriglyceridemia (OR=1.66, 95%CI=1.02～2.74) were associated with development of MAS in AOSD. Conclusion The development of MAS in AOSD patient is frequent and hemophagocytic histological evidence could be found in severe cases. When splenomegaly and hypocytomsis present in AOSD patients, bone marrow examination should be done and the level of triglyceride and fibrinogen and activity of NK cells should be measured for early diagnosis.
ABSTRACT
Objective To explore the efficacy of tumor necrosis factor inhibitor in hip joint lesion of ankylosing spondylids (AS). Methods Eight-six patients with hip joint lesion of ankylosing spondylitis were Enrolled in this study. The treatment protocol was: ①Etanercept 25 mg was suncutaneously injected twice a week in the first two months and once a week in the following two months. Then it was injected once every oth-er two weeks in the last two months of the study period.②Methotrexate 15 mg was administered orally or in-travenously once a week.③NSAIDs and prednisone were stopped when symptoms sunsides. Results Twenty-eight cases (33%) stopped NSAIDs because of the disappearance of symptoms in 2 weeks after starting of the study. Forty-three (50%) stopped NSAIDs with in 8 weeks and 36 cases (42%) in them stopped NSAIDs and prednisone. During the 9th and 16th week, etanercept was used once a week and 49 cases (60%) stopped NSAIDs and prednisone. During the 17th and 24th week, etanercept was used once every two weeks, and 38 cases (44%) stopped NSAIDs and prednisone and their disease was stable. Hip Functional Scores of patients were elevated significantly at 2, 4 and 6 months after the treatment (p<0.05) BASDAI and BASFI decreased, and the difference was significant when compared to those before the treatment (P<0.05). For the 19 cases with hip joint synovitis and hydrarthrosis in MRI image but without obvious change in pelvic plain films, syn-ovitis of 11 cases disappeared and 4 cases improved significantly. In 84 hip joints with grade Ⅱ or Ⅲ changes, 13 joints improved for one grade, 16 joints had improvement but less than one grade, and 49 joints had no radiological changes. Conclusion Etanercept, when combined with methotrexate, is effective in treat-ing hip joint lesion of ankylosing spondylitis. The dosage of etanercept can be tapered after the disease is un-der control.
