To research the association between primary progressive pterygium and tear film.
●METHODS: Totally 60 cases of primary progressive pterygium from September 2012 to June 2013 in our hospital were enrolled. The pterygium eye was for observation group and the contralateral eye as the control group. The differences of eye symptoms, tear film break-up time ( BUT ), Schirmer Ⅰ test ( S Ⅰ t ), corneal fluorescein staining (FL), tear ferning test (TFT) and the conjunctival impression cytology ( ClC) were compared between two groups.
●RESULTS: The eyes in observation group had higher symptoms score, FL score, grades of conjunctival squamous metaplasia, percentage of abnormal tear ferning, but had lower BUT and density of goblet cell, the differences had statistically significance (P<0. 05); Similar S Ⅰ t results were presented in the two groups, the difference had no statistically significance (P>0. 05).
● CONCLUSlON: Primary progressive pterygium can cause a decrease in tear film stability, which in turn lead to some dry eye symptoms such as dry feeling and burning sensation, and its mechanism may be caused by multi-factors, such as density change of goblet cell and the tear fluid dynamics.

Objective:To investigate the clinicopathological and immunohistochemical features, histogenesis and biologic behaviors of choroids plexus tumors of the cerebellopontine(CP) angle. Methods:Four cases of choroids plexus tumors of the CP angle were studied by histopathological analysis, immunohistochemical staining and electron microscopic examination. The literatures were review emphasising the diagnostic criteria, differential diagnosis and histogenesis. Results:The histopathologic features of choroid plexus tumors of the CP angle were identical to that in the ventricular system. Immunohistochemical analysis showed that S-100, vimentin and CK of the tumor cells express positive. Choroid plexus papilloma expressed GFAP. The carcinoma of choroid plexus expressed CEA as well. Conclusion:Choroid plexus tumors arising in and occupying the CP angle are rare. The final diagnosis can be made by pathologic examination. The histogenesis may be the small choroid tuft protruding from the foramen of Luschka into the CP angle.

The number of puncture point was 1～2.The number of puncture direction was 2-5 times.Results Regarding 32 cases for 1 month,the size of the tumor reduced in 11 cases,no change in 20 cases,and increased in 1 case.As for 31 cases for 2 months,the size reduced in 16 cases,no change in 13 cases,and enlarged in 3 cases.Regarding 30 cases for 3 months,the size reduced in 18 cases,no change in 11 cases,and increased in 3 cases. Regarding 28 cases for 6 months, he size reduced in 10 cases, no change in 5 cases, and in- creased in 13 cases.Regarding 22 cases for 1 year,12 cases had been done the second therapy,the size of the tumor reduced in 16 cases,no change in 3 cases,and increased in 3 cases.Conclusion The size of pancreas tumors were reduced obviously,the symptoms were relieved after the treatment.The method turned out to be safe and accurate.

Objective To investigate the effect of hyperbaric oxygen therapy on T-lymphocyte subpopulations in rats with acute pancreatitis. Methods 56 rats were randomly divided into three groups the sham group ( n = 8 ),control group( n = 24) and hyperbaric oxygen therapy group( treatment group, n = 24), then the control group and treatment groups were divided into three subgroups of 8 rats each undergoing euthanasia on days 1,3,7 after the acute pancreatitis induction. The CD4+ ,CD8+ subpopulations of T-lymphocytes in peripheral blood were detected respectively at the fist day and each day of the euthanasia. The sham group was used to make sure that the model was successfully induced. After euthanasia the pancrea was examined using electron microscopy. Results In the control group, the CD4+ cells in AP rats was significantly decreased and the ratio of CD4+/CD8+ also decreased. After 7days of HBO therapy,compared with the control group, the CD4+ lymphocytes of peripheral blood in the treatment group markedly increased( P ＜0.01 ). The CD8+ lymphocytes also increased to a certain extent. And the CD4+/CD8+ ratio of peripheral blood was obviously increased(P ＜0. 01 ). Also more severe pathological changes appeared in the untreated group than in the treatment group. Conclusion Hyperbaric oxygen therapy could improve the oxygen supply in acute panereatitis, regulate T cell immune function.

Abstract:Objective To detect the expression of hepatic function indices and autoantibodies in patients with chronic hepatitis B patients, patients with autoimmune liver disease and patients with chronic hepatitis B combined with autoimmune liver disease, and to evaluate the clinical significance of autoantibodies and hepatic function indexes in the early diagnosis of chronic hepatitis B combined with autoimmune liver disease.Methods A total of 109 healthy controls (HC), 72 patients with chronic hepatitis B (CHB), 74 patients with autoimmune liver disease (AILD), and 24 patients with chronic hepatitis B combined with autoimmune liver disease (CHB+AILD) in the Fifth People’s Hospital of Suzhou from 2013 to 2021 were enrolled in this study. Basic information and the value of admission hepatic function indexes and autoantibodies were collected for all enrolled samples, while no autoantibody test was performed for healthy volunteers. All data were processed using GraphPad Prism and SPSS software.Results There were no significant differences in age and gender among the four groups. The detection rates of anti-mitochondrial antibody M2 (AMA-M2) and anti-soluble acidic phosphorylated nuclear protein antibody (anti-SP100 antibodies) in CHB+AILD group [29.2%(7/24), 17.4%(4/23)] were significantly higher than those in CHB group [5.1%(3/59), 0(0/59)], suggesting that the detection of these two autoantibodies is helpful to the differential diagnosis of CHB and CHB+AILD. In addition, eight hepatic function indexes displayed significant differences among the four groups. The levels of total bilirubin and direct bilirubin in CHB+AILD group were significantly higher than those in CHB and AILD groups, while the levels of total protein and albumin were significantly lower than those in CHB and AILD groups. Alkaline phosphatase and glutamyltranspeptidase in AILD group and CHB+AILD group were significantly higher than those in CHB group. The logistic regression analysis showed that total bilirubin, direct bilirubin, albumin, alanine aminotransferase and alkaline phosphatase could form a promising prediction model, which was useful for clinicians in the differential diagnosis of CHB and CHB+AILD (area under the curve, AUC=0.902).Conclusion The combination of autoantibody and hepatic function index detection can be helpful for clinicians in the differential diagnosis of CHB, AILD and CHB+AILD, thus contributing to the early and correct diagnosis of CHB+AILD and providing theoretical basis for patients to obtain reasonable treatment and clinical cure earlier.

Objective To investigate the diagnostic value of serum liver function indexes for gallbladder stones combined with asymptomatic secondary common bile duct stones.Methods The retrospective cohort study was conducted.The clinical data of 460 patients with gallbladder stones who were admitted to the Affiliated Hospital of Zunyi Medical College from June 2012 to June 2016 were collected.Of 460 patients,106 combined with asymptomatic secondary common bile duct stones and 354 with gallbladder stones were allocated into the common bile duct stone group and gallbladder stone group,respectively.The serum liver function test was applied to the 2 groups,including alanine transaminase (ALT),aspartate transaminase (AST),total bilirubin (TBil),direct bilirubin (DBil),glutamyltransferase (GGT) and alkaline phosphatase (ALP).The receiver operating characteristic (ROC) curve was built using significant statistical indicators,and correspondent cut-off value,sensitivity and specificity were calculated according to ROC curve.Observation indicators:(1) comparison of serum liver function indicators (ALT,AST,TBil,DBil,GGT,ALP) between the 2 groups;(2) analysis result of ROC curve.Measurement data with normal distribution was represented as x±s.The comparison between groups was evaluated with the independent-sample t test.The comparison of count data were analyzed using the chi-square test.The ROC curve analysis was done for significant statistical indicators.Results (1) Comparison of serum liver function indicators between the 2 groups,the levels of ALT,AST,TBil and DBil were (32±8)U/L,(35±8)U/L,(12.8±2.5)μmol/L,(2.6±0.4)μmol/L in the common bile duct stone group and (30±7)U/L,(32±7)U/L,(12.2± 2.4)μmol/L,(2.5 ±0.4)μmol/L in the gallbladder stone group,respectively,with no statistically significant difference (t=0.891,0.786,0.924,1.026,P＞0.05).The levels of GGT and ALP were (162±43) U/L and (145±37) U/L in the common bile duct stone group and (36± 10)U/L and (128±23) U/L in the gallbladder stone group,respectively,with significantly statistical differences (t =20.859,2.483,P＜0.05).(2) Result of ROC curve showed that areas under the curve of GGT and ALP were respectively 0.963 [95％ confidence interval (CI):0.938-0.988] and 0.621 (95％CI:0.561-0.684).The correspondent cut-off value of diagnostic accuracy,sensitivity and specificity of GGT and ALP were 92.5 U/L and 139.5 U/L,91.6％ and 50.7％,95.7％ and 76.5％,respectively.Conclusion The abnormally elevated levels of serum GGT have major diagnostic value for patients with gallbladder stones combined with asymptomatic secondary common bile duct stones,with an advantage of convenient and fast operation,and it is worth to be applied and popularized.

ObjectiveTo evaluate the influence of different hemoperfusion (HP) intensity on 7-day and 28-day mortality for patients with paraquat (PQ) poisoning, and examine the factors that may affect the decision of the clinicians to prescribe a high intensity HP.Methods A retrospective cohort study was conducted. The patients admitted to the department of critical care medicine of Anhui Provincial Hospital Affiliated to Anhui Medical University with the diagnosis of PQ poisoning from August 2012 to August 2014, fulfilling the following criteria were enrolled in the study: older than 18 years, interval from ingestion PQ to hospital admission shorter than 12 hours, and receiving HP treatment within 24 hours, and expecting surviving time exceeding 24 hours after admission, and data of the patients available for at least 28 days after admission. Depending on the intensity of HP, patients were assigned to either lower intensity HP group (LHP, defined as receiving HP for less than 4 hours, 2 columns) or higher intensity HP group (HHP, defined as receiving HP longer than 6 hours, 3 columns). Patients' data were retrieved from hospital's electronic database after hospital admission, and the results at 7th day and 28th day were recorded. Multiple logistic regression model was used to determine factors with which the clinician decided to choose the intensity of HP for the patients, and Cox regression model was used to evaluate 7-day and 28-day mortality.Results Data of 60 patients was finally available for this study. LHP group consisted of 28 patients, with a 7-day mortality of 53.6%(15 patients) and 28-day mortality of 64.3% (28 patients); 32 patients were assigned to HHP group with 7-day mortality of 43.8% (14 patients) and 28-day mortality of 62.5% (20 patients). Twenty-eight patients constituted as the HHP group, with higher PQ concentration in plasma, higher incidence of respiratory alkalosis and acute kidney injury (AKI), and higher level of lactate (Lac) compared with LHP group. However, a lower 7-day mortality was observed in the HHP group. Multiple logistic regression model indicated that at admission, interval from ingestion PQ to hospital admission longer than 4 hours [odds ratio (OR) = 1.461, 95% confidence interval (95%CI) = 1.132-1.435,P< 0.001], younger than 50 years old (40-49 years old:OR = 1.397, 95%CI = 1.251-1.703,P = 0.002;< 40 years old:OR = 1.701, 95%CI = 1.253-1.836,P< 0.001), PQ plasma concentration≥ 2 mg/L (OR = 3.140, 95%CI = 1.511-3.091,P< 0.001), white blood cell (WBC)> 10×109/L (OR = 1.222, 95%CI = 1.032-1.275, P = 0.018), Lac> 2.0 mmol/L (OR = 2.392, 95%CI = 2.090-2.734,P< 0.001), AKI on admission (stage 2:OR = 2.350, 95%CI = 2.160-3.910,P< 0.001; stage 3:OR = 2.821, 95%CI = 1.932-3.651,P< 0.001), accompanying hypoxia (OR = 2.420, 95%CI = 2.131-2.662,P = 0.003) were more likely to receive higher intensity of HP. Furthermore when compared with patients survived for 28 days, patients who were older, with higher levels of PQ concentration at admission or after 4 hours of HP, accompanied by AKI, increased serum creatinine (SCr), WBC, Lac, and acute physiology and chronic health evaluationⅡ (APACHEⅡ) score, lower arterial partial pressure of carbon dioxide (PaCO2) and lower pH value were more likely to die. After adjusted for con-variables in COX regression model, HHP was associated with lower 7-day mortality after admission [hazard ratio (HR) = 0.843, 95%CI = 0.732-0.971, P = 0.032], but devoid of lowering effect on 28-day mortality rate (HR = 0.930, 95%CI = 0.632-1.411,P = 0.423). In addition, age> 50 years old (HR = 1.282, 95%CI = 1.050-1.530,P = 0.043), PQ concentration increased by 1 mg/L (HR = 2.521, 95%CI = 2.371-3.825,P = 0.012), AKI on admission (HR = 3.850, 95%CI = 2.071-5.391,P< 0.001), WBC>10×109/L (HR = 1.932, 95%CI = 1.782-2.171,P = 0.006), Lac> 2.0 mmol/L (HR = 2.981, 95%CI =2.210-3.792,P = 0.002), and PaCO2< 35 mmHg (HR = 1.772, 95%CI = 1.483-2.516,P = 0.008; 1 mmHg =0.133 kPa) were independent risk factors for 28-day mortality.Conclusions Though HHP was helpful in lowering mortality rate in patients with PQ poisoning within 7 days, it did not influence on 28-day mortality. Clinicians' decisions on HP intensity need further investigation, and more perfect clinical evaluation system is required for reasonable use of expensive medical resources such as HP.

Objective To discuss the clinical features diagnosis and treatment of cerebral schistosomiasis. Methods A to?tal of 166 patients with cerebral schistosomiasis were treated and their clinical data were collected and analyzed retrospectively. Results In 166 cases of cerebral schistosomiasis the confirmative diagnoses of 156 cases were diagnosed according to the clin?ical manifestation etiology immunology and auxiliary examination CT MRI .In among 74 cases were confirmed by pathologi?cal examination 10 cases were diagnosed through to the diagnostic treatment. Totally 102 patients received the oral medication of praziquantel and they all improved and discharged 14?16 days later 64 patients received the craniotomy and praziquantel medication after the operation and 48 patients significantly improved others did not improve or aggravated. There was no opera?tive mortality. Conclusions Neuroimaging and laboratory tests are valuable in the diagnosis of cerebral schistosomiasis. The praziquantel treatment is selected firstly when the diagnosis was established. However in the case of serious intracranial hyper?tension intractable epilepsy and praziquantel treatment fails the surgical treatment is required.
