Objective To evaluate the significance of combined detection of leptin (LEP),tumor necrosis factor-α (TNF-α),carcino-embryonic antigen (CEA),C-reactive protein (CRP) and interleukin-6 (IL-6) in both serum and pleural effusion in differential diagnosis of tuberculosis and malignant tumor.Methods LEP,TNF-α,CEA,CRP and IL-6 levels in both pleural fluid and serum samples from 95 cases of pleural effusion (including 54 cases of malignant pleural effusion and 41 cases of tuberculous pleural effusion) were detected by immunoturbidimetry and enzyme linked immunosorbent assay (ELISA),respectively.The data with normal distribution and skewed distribution were analyzed by t test and rank sum test,respectively.Results In patients with tuberculosis and malignant tumor,significant difference was observed in serum LEP [(0.42±0.47) ng/ mL vs (1.80±0.91) ng/mL,t=9.666,P=0.0001],TNF-α [(30.88±24.72) pg/mL vs (59.83±30.93) pg/mL,t=4.917,P=0.0001],CEA [(0.22±0.30) ng/mL vs (5.67±3.60) ng/mL,t=ll.074,P=0.0001] and IL-6 [(146.48±54.90) pg/mL vs (20.51±11.62) pg mL,t=-14.449,P 0.0001] levels.Serum CRP levels of patients with tuberculosis and malignant tumor were comparable [(32.78±22.43) mg/mL vs (37.80±16.74) mg/mL,t =1.249,P=0.215].In pleural effusion of the two groups (tuberculous pleural effusion vs malignant pleural effusion),LEP [(0.69±0.65) ng mL vs (4.33±2.16) ng mL,t 11.711,P 0.0001],TNFα [(20.60±17.80) pg/ mL vs (40.40±20.60) pg/mL,t=4.926,P=0.0001],CEA [(0.10±0.17) ng/mL vs (4.02±2.49) ng/ mL,t=11.537,P=0.0001] and IL-6 [(87.80±48.40) pg/mL vs (9.30±5.50) pg/mL,t =-10.333,P=0.0001] levels were significantly different,while CRP levels [(27.34±17.93) mg mL vs (29.60± 13.40) mg mL,t =0.709,P =0.102] were comparable.Conclusion LEP,TNF-α,and CEA levels in both pleural effusion and serum samples from patients with malignant tumor are higher than those with tuberculosis,while IL 6 levels are quite opposite.Combined detection of these parameters can help the differential diagnosis of tuberculous and malignant pleural effusion.

PURPOSE: In recent years, a variety of acute respiratory distress syndrome (ARDS) evaluation systems have been developed worldwide; however, they are not so convenient for the doctors clinically, we decided to establish and evaluate a simplified evaluation system of ARDS (SESARDS). MATERIALS AND METHODS: Data from 140 ARDS patients (derivation data set) were collected to screen for prognostic factors affecting outcomes in ARDS patients. By logistic regression analysis, scores were allocated to corresponding intervals of the variables, respectively, by means of analysis of the frequency distribution to establish a preliminary scoring system. Based on this primary scoring system, a definitive evaluation scheme was created through consultation with a panel of experts. The scores for the validation data set (92 cases) were assigned and calculated by their predictive mortality with the SESARDS and acute physiology and chronic health evaluation II (APACHE II). The performance of SESARDS was compared with that of APACHE II by means of statistical analysis. RESULTS: The factors of age, pH, Glasgow coma scale (GCS), oxygenation index (OI), and the lobes of lung were associated with prognosis of ARDS respectively. The sensitivity and specificity of SESARDS for the validation data set were 96.43% and 58.33%, respectively. On the AUC, no significant difference between APACHE II and SESARDS was detected. There were no significant differences between the prediction and the actuality obtained by SESARDS for the validation data set the SESARDS scores were positively correlated with the actual mortality. CONCLUSION: SESARDS was shown to be simple, accurate and effective in predicting ARDS progression.

Liver transplantation(LT)is the only effective treatment for hepatopulmonary syndrome(HPS).Moreover,perioperative refractory hypoxemia(pRH)is a prevalent life-threatening condition and has extremely limited treatment options.Here,we report three patients with HPS who experienced pRH after LT and were consecutively treated with different salvage therapies,ephedrine inhalation,intravenous use of methylene blue with nitric oxide(NO)inhalation,and NO inhalation alone.The results showed that unresolved severe hypoxia may induce fatal morbidity such as early biliary leakage and acute kidney injury.Early initiation of NO inhalation,rather than ephedrine,can significantly improve oxygenation in patients with pRH and may help prevent hypoxia-related complications.Therefore,based on the response to these exploratory salvage treatments,we further demonstrate the unique ventilation-perfusion mismatch pathophysiology in specific lung regions during pRH in HPS.We propose that early inhalation of NO is an important treatment option to rescue severe hypoxia in patients with HPS during the perioperative period of LT.

Objective To investigate the rationality and efficacy of enhanced recovery after surgery (ERAS) in liver transplant recipients. Methods Clinical data of 465 liver transplant recipients were retrospectively analyzed. All recipients were divided into the ERAS group (n=163) and control group (n=302) according to whether they received ERAS. The severity of disease in the ERAS group was worse than that in the control group. Operation situations including the operation time, anhepatic phase and intraoperative blood transfusion volume of the liver transplant recipients were observed and recorded. Postoperative recovery conditions including the length of intensive care unit (ICU) stay, total length of hospital stay, total ventilator removal time at postoperative 28 d and postoperative re-intubation rate were recorded. The survival rates at 90 d, 180 d and 1 year after liver transplantation were calculated. The influencing factors of survival rate of liver transplant recipients were analyzed. Results The anhepatic phase in the ERAS group was 45 (39, 53) min, significantly longer than 40 (32, 48) min in the control group (P < 0.05). The volume of erythrocyte infusion in the ERAS group was 10 (7, 13) U, significantly less than 18 (10, 28) U in the control group (P < 0.05). The length of postoperative ICU stay and total length of hospital stay in the ERAS group were 135 (84, 212) h and 24 (18, 33) d, significantly shorter than 154 (103, 253) h and 34 (20, 50) d in the control group (both P < 0.05). Total ventilator removal time at postoperative 28 d was 26 (25, 27) d, significantly longer than 26 (23, 27) d in the control group (P < 0.05). The postoperative re-intubation rate in the ERAS group was 11.0%, significantly lower than 20.8% in the control group (P < 0.05). The 90 d, 180 d and 1-year survival rates in the ERAS group were 92.8%, which were significantly higher than 81.1%, 78.1% and 75.7% in the control group (all P < 0.05). ERAS and operation time were the independent influencing factors of survival rate of liver transplant recipients (both P < 0.05). Conclusions ERAS after liver transplantation can improve the survival rate of recipient, shorten the length of hospital stay, reduce the re-intubation rate and accelerate the rehabilitation after liver transplantation.

Objective To summarize the treatment experience of sepsis after liver transplantation.Methods The clinical features and treatment methods of 1 patient developing sepsis after liver transplantation, who was admitted and treated in the Surgical Intensive Care Unit of the Third Affiliated Hospital of Sun Yat-sen University in September 201 4,were retrospectively studied.The interpretation of International Guidelines for Management of Severe Sepsis and Septic Shock (SSC Guidelines)and relevant literature were reviewed.Results One male patient at the age of 50 years old developed high fever and decrease of blood pressure at 1 d after liver transplantation,and was diagnosed as septic shock.The symptoms were relieved after the appropriate treatment like goal-directed fluid resuscitation,anti-infection and blood purification,etc.And the patient was discharged in stable conditions.Conclusions It is easy to develop infection after liver transplantation and the fatality rate of sepsis caused by infection is high.Once the sepsis occurs,clinicians must perform early goal-directed therapy and bundle therapy according to the SSC Guidelines positively,and select the appropriate drugs according to the pathogen culture results in order to reduce the fatality rate.

Objective:To evaluate the immunogenicity and immune persistence of purified Vero cells rabies vaccine (PVRV) with Zagreb and Essen regimen.Methods:Prospective study: Patients with first Class II exposure to rabies were recruited from the Dog Injury Cinic of Guangxi Center for Disease Control and Prevention (Guangxi CDC) and randomly divided into the Zagreb (2-1-1) and Essen (1-1-1-1-1) regimen group. All patients were inoculated with the vaccines from the same manufacturer and batch, and 3 ml serum was collected at the 45th day and in 1-year, 2-year and 3-year after immunization. Rapid fluorescent inhibition test (RFFIT) was used to detect rabies virus neutralizing antibody (RVNA). The attenuation of RVNA positive rate and geometric mean titer (GMT) with time was analyzed. Retrospective study: The informed consents for rabies vaccine in the Dog Injury Clinic of Guangxi CDC were checked out. The patients who were injected with PVRV (same manufacturer but unlimited batch) but without passive immune agents for the first time within 3 years were selected and divided into 1-year, 2-year and 3-year group. Each group was further divided into Zagreb and Essen regimen group. The serum (3 ml) was collected at 1 year, 2 years and 3 years after immunization and detected the RVNA by RFFIT.Results:Prospective study: The RVNA positive rates on the 45th day and in 1-year, 2-year and 3-year after immunizationin in the Zagreb and Essen regimen group were 100%, 95%, 85%, 80% and 98.25%, 89.47%, 89.47%, 85.96%, respectively. There was no statistically significant difference in the RVNA positive rates at the same time point between the two regimen groups ( P>0.05). The RVNA GMT on the 45th day and in 1-year, 2-year, and 3-year in the Zagreb and Essen regimen group were 11.32 IU/ml, 1.69 IU/ml, 1.30 IU/ml, 1.30 IU/m and 13.18 IU/ml, 2.13 IU/ml, 1.87 IU/ml, 1.84 IU/m, respectively. There was no significant difference in the RVNA GMT levels at the same time point between the two regimen groups ( F=1.971, P=0.164). The RVNA GMT levels in the two regimen groups had the same trend of attenuation over time (time*group F=0.702, P=0.435). Retrospective study: The RVNA positive rates in 1-year, 2-year and 3-year after immunization in the Zagreb and Essen regimen group were 100%, 95%, 91.43%和94.73%, 86.21%, 87.5%, respectively. There was no statistically significant difference in the RVNA positive rates at the same time point between the two regimen groups ( P>0.05). The RVNA GMT in 1-year, 2-year, and 3-year groups after immunization in the Zagreb and Essen regimen group were 2.65 IU/ml, 2.03 IU/ml, 1.57 IU/ml和3.2 IU/ml, 2.58 IU/ml, 2.45 IU/ml, respectively. There was no significant difference in the RVNA GMT levels at the same time point between the two regimen groups ( P>0.05). Conclusions:The PVRV showed the same excellent immunogenicity and immune persistence after the vaccination with the Zagreb and Essen regimens.

Objective To investigate the therapeutic effect and safety of plasma exchange in the treatment of patients with severe liver disease in pregnancy. Methods Clinical data of 28 patients with severe liver disease in pregnancy in Surgical Intensive Care Unit (SICU), the Third Afifliated Hospital of Sun Yat-sen University from March 2009 to October 2013 were analyzed retrospectively. According to the therapeutic schedule, the patients were divided into treatment group (n=12, age range:21 to 28 years old, median age:25 years old) and control group (n=16, age range:18 to 29 years old, median age:24 years old). The informed consents of all patients were obtained and the ethical committee approval was received. All patients were transferred to SICU after childbirth and received treatments of anti-infection, anti-virus, liver protection, reducing jaundice, supplying human albumin and gamma globulin, infusing blood coagulation and so on. And patients in treatment group received the treatment of exchange of homotype fresh plasma on the basic of the above treatments. The differences between 2 groups in clinical examination indicators and therapeutic effect were compared. The adverse reactions after plasma exchange in treatment group were observed. The examination indicators of 2 groups were compared using t test and the ratios were compared using Chi-square test. Results The blood total bilirubin (TB), albumin (ALB) , serum creatinine (Scr), fasting blood glucose (FPG) , prothrombin time activity (PTA) and arterial lactic acid (Lac) were (197±69)μmol/L, (30±7)g/L, (111±42)μmol/L, (5.7±2.4)mmol/L, (55±24)%, (2.3±0.6)mmol/L respectively in treatment group and were (299±113)μmol/L, (24±6)g/L, (165±82)μmol/L, (3.7±1.7)mmol/L, (33±11)%, (4.4±1.5)mmol/L respectively in control group. The indicators in treatment group were signiifcantly improved compared with those in control group (t=-3.453, 2.389,-4.892, 2.798, 6.079, -3.339; P<0.05). The effective rate in treatment group (92%,11/12) was signiifcantly higher than that in control group (56%,9/16) ( χ2=4.215, P<0.05). One case in treatment group suffered transitional hypotension after plasma infusion and the blood pressure returned to normal 1 h later after giving a small dose of vasoactive drugs. Conclusions Plasma exchange can improve the clinical examination indicators and therapeutic effect of patients with severe liver disease in pregnancy. It is a safe and effective treatment.

OBJECTIVETo observe the effects of micro-invasive embedding combined with montelukast sodium and simple montelukast sodium for children cough variant asthma (CVA).

METHODSA total of 240 patients were randomly assigned into an observation group and a control group, 120 cases in each one. Considering of cases dropping, 101 patients in the observation group and 105 cases in the control group were included. Montelukast sodium chewable tablets were applied before sleep for 3 months in the control group, 5 mg a time, once a day. Based on the treatment as the control group, micro-invasive embedding was used for 3 months in the observation group, twice in the first month and once in the other two months. The acupoints were Feishu (BL 13), Danzhong (CV 17), Dingchuan (EX-B 1), and Zusanli (ST 36). Follow-up was conducted 9 months after treatment in the two groups. The cough score, serum immunoglobulin (IgE, IgG, IgA), platelet activating factor (PAF) were observed before and after treatment. The indices were compared before and after treatment and at follow-up, including pulmonary function indices[peak expiratory flow rate (PEF), forced expiratory volume at the 1st second (FEV1)], and small airway function indices[forced expiratory flow rate with remaining 25% vital capacity (MEF25%), forced expiratory flow rate with remaining 50% vital capacity (MEF50%), forced expiratory flow rate with remaining 75% vital capacity (MEF75%) and mid expiratory flow rate (MEF25%-75%)]. Also, the total effects were evaluated.

RESULTS①The total effective rate in the observation group was 93.1% (94/101), which was better than 87.6% (92/105) in the control group (<0.05). The cough disappearance time of the cured children in the observation group was (10.38±2.64) d, and it was shorter than (10.72 ±2.60) d of those in the control group (<0.05). After treatment, the cough score apparently decreased compared with those before treatment in the two groups (both<0.05), with better result in the observation group (<0.05). At follow-up, the recurrence frequency of the observation group was (1.43±1.20), and it was less than (1.91±1.71) in the control group (<0.05). ②The levels of serum IgA and IgG after treatment in the two groups increased, and those of serum IgE and PAF decreased, compared with those before treatment. There was statistically significance except IgG in the control group before and after treatment (all<0.05), with better Results in the observation group after treatment (all<0.05). ③ Compared with those before treatment, all the pulmonary function indices were improved obviously after treatment and at follow-up in the two groups (all<0.05), without statistically significance between the two groups (both>0.05). ④ There was no statistically significance before and after treatment on small airway function indices in the two groups (all>0.05). The indices at follow-up increased compared with those before treatment in the two groups (all<0.05), with better Results in the observation group (all<0.05).

CONCLUSIONSMicro-invasive embedding combined with montelukast sodium achieved de-finite effect for children CVA, which can improve the body's immune and microcirculation. The effect is better than that of simple montelukast sodium on improving small airway function, etc.
