Objective To explore the characteristics of clinical features,diagnosis,treatment and prognosis in acute fibrinous and organizing pneumonia (AFOP) patients.Methods We described an 80-year-old woman who was diagnosed with AFOP and got better after treatment with glucocorticoids.Clinical data of 51 patients which have been published in literatures in China and abroad were retrospectively analyzed.The differences in characteristics of clinical features were compared between the elderly and non-elderly patients.Results The case reported herein,who was a 80-year-old female with latent autoimmune diabetes in adults (LADA),presented with fever,dry cough and progressive dyspnea.Chest CT scan showed bilateral multiple patchy consolidation.CT-guided needle aspiration was performed and the pathological examination finding was consistent with AFOP.The patient was treated with oral methylprednisolone and experienced a significant improvement in symptoms and imaging manifestations.But she presented with deterioration with relapsing clinical symptoms when she discontinued corticosteroid treatment by herself,and the clinical symptoms were improved by retreatment.Clinical data of 51 reported cases with AFOP including 27 males and 24 females aged 38 d to 80 years were enrolled and analyzed in the study.Patients aged 60 years and over accounted for 47.1％ (24 cases).No risk or predisposing factor was found in most of cases.Autoimmune diseases were the most common combined diseases in AFOP patients.The top three symptoms were dyspnea (80.4％,41 cases),cough (64.7％,33 cases) and fever (52.9％,27 cases).The incidence of dyspnea was lower in elderly patients than in non-elderly patients [66.7％ (16/24) vs.92.6％ (25/27),P＜0.05],and ground glass opacity in the chest image was also less in elderly patients than in non-elderly patients (P＜0.05).15 patients (29.4％) got definitive diagnosis by minimally invasive procedures including percutaneous lung puncture biopsy or transbronchial lung biopsy.Corticosteroids were the main drug treatment,and 39 cases (76.5 ％) received antibacterial drugs.The mortality rate of AFOP was 37.3％ (15 cases).The average time from symptom onset to final diagnosis was shorter in dead cases than in recovered patients (19 days vs.40 days,P＜0.05).The rate of using mechanical ventilation was higher in dead cases than in recovered patients [57.9 ％ (11/19) vs.9.4％ (3/32),P＜0.05].Conclusions There are no specific clinical and imaging features in AFOP,which is easily misdiagnosed as infectious diseases.AFOP is more common in elderly patients.Dyspnea and other symptoms can easily be ignored,and minimally invasive biopsy and pathological examination findings is helpful for diagnosis.The mortality rate of AFOP is high,and insufficient course of therapy is associated with the increased risk of AFOP relapse.Rapid progression of disease and the invasive mechanical ventilation predispose poor outcomes.

Objective:To compare the clinical effects and improvement of serum hormone levels of kidney tonifying and blood circulation recipe and mirena in the treatment of perimenopasual dysfunctional uterine bleeding.Methods:92 cases of perimenopausal patients with dysfunctional uterine bleeding in our hospital from July 2013 to November 2016 were selected and divided into group A and group B with 46 cases in each group.Group A was orally administered with kidney tonifying and blood circulation recipe,and group B was administered with mirena.Both groups were treated for 3 periods.The efficacy and incidences of adverse effect in two groups were observed.The levels of serum hormones and hemoglobin (Hb),and endometial thickness (ET) were detected in two groups.The indices of serum hormone included follicle-stimulating hormone (FSH),luteinizing hormone (LH),progestone (P) and estradiol (E2).Results:No significant difference was found in the total effective rate between two groups (P＞0.05).After treatment,the levels of serum FSH,LH,E2 and P as well as ET and Hb in both groups were all significantly lower than those before treatment (P＜0.01),and the levels of serum FSH,LH,E2 and P as well as ET of group B were significantly lower than those of group A (P＜0.01),no significant difference in the Hb level between two groups (P＞0.05).The incidence of adverse reactions of group B (15.22％) was significantly higher than that of group A(0％) (P＜0.01).Conclusions:The kidney tonifying and blood circulation recipe had similar effect as mirena in the treatment of perimenopasual dysfunctional uterine bleeding,while mirena had strong improving effect in serum hormone level and ET,kidney tonifying and blood circulation recipe had higher security.

Objective To observe the effect of flexible laryngeal mask (FLMA) in transnaso-sphenoidal microsurgery for pituitary adenoma on airway management and variation of stress response.Methods One hundred patients (71 males, 29 females, aged 18-65 years, BMI 21-28 kg/m2, ASA physical status Ⅰ or Ⅱ) undergoing transnaso-sphenoidal microsurgery for pituitary adenoma were randomly divided into two groups: the FLMA group (group F) and the reinforced endotracheal tube group (group T) using a random number table, 50 cases in each group.The plasma concentration of epinephrine and norepinephrine were measured before anesthesia induction (T0), at the time of inserting the FLMA or reinforced endotracheal tube (T1), 1 min (T2) and 5 min (T3) after insertion.The Berry scores of the preoperative and postoperative airway exposure by branchofiberoscope in group F were assessed.The time of removal of FLMA (endotracheal tube) and the occurrence of choking, laryngeal spasm, sore throat, hoarseness and other adverse reactions were recorded.Results The levels of epinephrine and norepinephrine were were significantly lower at T2 and T3 in group F than those in group T (P<0.05).There was no significant difference in airway Berry scores.The time of extubation was shorter in group F than that in group T [(9±3) min vs (17±6) min] (P<0.05).The incidence of choking (2% vs 22%) and sore throat (4% vs 30%) were significantly lower in group F than those in group T (P<0.05).Conclusion Compared with the reinforced endotracheal tube, FLMA can be applied safely and effectively to transnaso-sphenoidal microsurgery for pituitary adenoma, reduces stress respond associated with anesthesia and post-extubation complications, improves the recovery of patients.

Objective To observe the effect of goal-directed fluid therapy on hemodynamic and regional cerebral oxygen saturation (rSO 2 )in the elder patient undergoing one-lung ventilation. Methods Fifty-eight patients scheduled for esophagus cancer resection(44 males,14 females,aged 65-79 years,ASA physical status Ⅱ or Ⅲ),were randomly divided into two groups (n =29 each)u-sing a random number table:conventional fluid therapy group (group C)and goal-directed fluid ther-apy group (group G).Implementing radial artery puncture and internal jugular vein puncture under local anesthesia in order to monitor BP and CVP.The Flotrac/Vigileo system was used to monitor cardiac output (CO),stroke volume variation (SVV)and cardiac index (CI)in the both group.As mentioned all above,group C received conventional fluid therapy based on MAP,CVP and urine vol-ume,whereas group G received goal-directed fluid therapy (GDFT)based on SVV with the goal of CI at 2.5-4.0 L·min-1·m-2 .Intraoperative continuous monitoring of rSO 2 was performed and the sur-gery rSO 2 average (rSO 2 ),the minimal surgery rSO 2 (rSO 2min )and the maximal percentage of the decreased rSO 2 compared to baseline values (rSO 2%max )were calculated in the both group.The varia-tion of MAP,HR,CVP,SVV and CI at the onset of the monitoring (T1 ),the momment before one-lung ventilation (T2 ),30 min after one-lung ventilation (T3 ),1 h after one-lung ventilation(T4 )and the end of the surgery (T5 )were recorded.The requirement for crystalloid and colloid,total volume of fluid infused,bleeding volume,urine volume,and requirement for vasoactive agents were recorded during operaton.Results Compared with group C,MAP at T3 ,T4 and CI at T3-T5 in group G were increased significantly,while CVP at T3-T5 and SVV at T2-T5 in group G were decreased (P <0.05). The rSO 2%max in group G was significantly lower than that in group C (P <0.05).No statistically sig-nificant difference was observed in the rSO 2 and rSO 2min between the two groups.Compared with group C,the requirement for crystalloid [(668±187)ml vs (1052±221)ml and total volume of fluid infused [(1212±318)ml vs (1519±329)ml],urine volume [(211±47)ml vs (278±54)ml]and vasoactive agents [4 cases (14%)vs 14 cases (48%)]were significantly decreased (P <0.05),the requirement for colloid were increased [(544±103)ml vs (467±94)ml,P <0.05].Conclusion The goal-directed fluid therapy based on SVV stabilizes the hemodynamic effectively,improves the CI and the perfusion of brain,and maintains the cereral oxygen metabolism in the elder patient undergoing one-lung ventilation.

Objective To explore the changes in serum concentrations of irisin,vaspin and reactive oxygen species (ROS) in patients with type 2 diabetes mellitus (T2DM) and metabolic syndrome (MS),and to investigated the correlation of irisin and vaspin with clinical parameters of MS.Methods A total of 260 T2DM patients were enrolled.Age and gender were recorded,anthropometrics,biochemical parameters,and levels of irisin,vaspin and ROS in fasting serum were measured,and homeostatic model assessment of insulin resistance (HOMA-IR) calculated.Wilcoxon rank sum test,correlation analysis,Logistic regression analysis,multiple linear regression analysis and receiver operating characteristic (ROC) curve analysis were performed.Results Compared to T2DM patients without MS,T2DM patients with MS had lower serum level ofirisin [male:112.81 (86.96-191.84) μg/Lvs.156.23 (110.61-225.97) μg/L,female:141.09 (77.52-175.55) μg/L vs.172.15 (95.69-240.37) μg/L,P ＜0.01],higher levels of vaspin and ROS [male:1.13 (0.95-1.38) μg/Lvs.0.36 (0.21-0.82) μg/L,1 540 (1 250-1 860) kU/Lvs.1 020 (920-1 350) kU/L;female:1.52 (1.13-1.80) μg/Lvs.0.51 (0.47-1.08) μg/L,1 650 (1 320-1 940) kU/Lvs.1 120 (980-1 420) kU/L,P ＜0.01].In the T2DM patients,serum irisin level was negatively correlated with vaspin (r =-0.382,P ＜ 0.01) and ROS (r =-0.410,P ＜ 0.01),while vaspin was positively correlated with ROS (r =0.400,P ＜ 0.01).Multiple linear regression analyses showed that irisin was significantly correlated with body mass index (BMI),waist circumference and triglyceride,while vaspin was correlated with gender,BMI,and waist circumference (all P ＜ 0.05).Logistic regression analysis revealed that irisin,vaspin and ROS were all associated with MS (OR =0.77,95 ％ CI 0.608-0.978;OR=1.39,95％ CI 1.252-1.539;OR=1.38,95％ CI1.112-1.718,all P＜0.05).ROC analysis demonstrated that irisin and vaspin had significant area under the curve (AUC =0.931,P ＜0.01;AUC =0.777,P ＜ 0.01) for the prediction of MS.Conclusions Serum irisin level was significantly decreased,while vaspin and ROS were significantly increased in T2DM patients with MS.Irisin and vaspin were associated with clinical presentations of MS,suggesting that irisin and vaspin might be valuable predictors of MS.

Objective To evaluate the efficacy and safety of oxycodone in patients undergoing microvascular decompression in treating trigeminal neuralgia and oxycodone versus sufentanil on early recovery after microvascular decompression in treating trigeminal neuralgia.Methods Eighty-six patients (38 males, 48 females, aged 18-65 years, BMI 18-30 kg/m2, ASA physical status Ⅰ or Ⅱ) scheduled for microvascular decompression in treating trigeminal neuralgia, were randomly divided into either oxycodone group (group O) and sufentanil group (group S) using a random number table, n=43 in each group.All patients received combined intravenous-inhalational anesthesia, as well as oxycodone 0.3 mg/kg injected intravenously in group O, sufentanil 0.4 μg/kg injected intravenously in group S for anesthesia induced analgesia.When the epidural was closed, oxycodone 0.07 mg/kg was injected intravenously in group O, sufentanil 0.1 μg/kg was injected intravenously in group S.On preoperative day 1 and 4, 24, 48 hours after surgery, numeric rating scale (NRS) was used to assess the incision pain and facial pain.When NRS scores≥4, oxycodone 3 mg in group O and sufentanil 5 μg in group S was injected intravenously as rescue analgesic.On preoperative day 1 and 3 days after surgery, the global QoR-40 aggregating score was used to assess the quality of patients recovery.The requirement for rescue analgesics was recorded.The occurrences of nausea and vomiting were recorded.Extubation time and discharge were recorded.The other adverse events (bradycardia, dysuria, dizziness and pruritus) were recorded.Results Compared with group S, the physical comfort score, the emotional state score, the psychological support score, the pain score and the global QoR-40 scores were higher in group O 3 days after surgery (P<0.05).Compared with group S, the incidence of nausea and vomiting was significantly lower in group O (20.9% vs 37.2%) (P<0.05).Conclusion In surgery less than 5 hours of microvascular decompression on treating trigeminal neuralgia, oxycodone 0.3 mg/kg can be safely and effectively used for anesthesia induction, oxycodone 0.07 mg/kg and 3 mg can be respectively used for postoperative prophylactic analgesia and remedial analgesia.Compared with sufentanil, oxycodone can improve the quality of recovery during the early period after microvascular decompression on treating trigeminal neuralgia, and decrease the incidence of nausea and vomiting.

Objective To study the changes and the role of MCP -1,IL -8,VEGF,NO,NOS in the T2DM patients with different types of CHD.Methods According to the result of coronary arteriongraphy and clinical symp-toms,and the diagnostic code of T2DM established by Chinese Medical Association diabetology branch in 2007, 126 patients of T2DMwith CHD were chosen and divided into two groups:ACS +T2DM group (A group,74 cases) and SAP +T2DMgroup (B group,52 cases),in addition,50 healthy people were chosen as control group.The levels of MCP -1,IL -8,VEGF were measured by the method of ELISA.The level of NO was measured by the method of nitrate reductase and NOS activity was measured by the method of spectrophotometer.Then,the results were analyzed. Results The levels of MCP -1 and IL -8 in A group and B group were[(115.98 ±39.57)pg/mL,(98.76 ± 31.55)pg/mL],[(131.22 ±42.83)pg/mL,(115.75 ±40.37)pg/mL],which were all higher than those in group C [(75.63 ±23.69)pg/mL,(68.53 ±37.85)pg/mL,t =4.12,2.26,3.78,2.21,all P <0.05)],but the VEGF [(167.87 ±54.98)pg/mL,(128.38 ±36.99)pg/mL)],NO[(46.89 ±12.92)μmol/L,(51.66 ±12.49)μmol/L)]and NOS [(39.04 ±5.19)U /mL,(40.56 ±7.03)U /mL)]were lower than those in C group [(90.21 ± 32.06)pg/mL,(64.05 ±13.58)μmol/L,(47.82 ±5.93)U /mL;t =3.05,3.17,2.43,2.79,2.49,2.25,all P <0.05].The MCP -1,IL -8 levels in A group were higher than those in B group(t =3.13,2.89,all P <0.05),but the level of VEGF and NO were lower than that in B group(t =3.04,2.95,all P <0.05),NOS in A group was lower than that in B group,but there was no statistically significant difference between the two groups(t =1.06,P >0.05). MCP -1 was positively correlated with Il -8,VEGF (r =0.35,0.33,all P <0.01),and it had negative correlation with NO (r =-0.24,P <0.05).Conclusion Inflammatory factor and oxidative stress both participate in the T2DM with different types of CHD,it relates with the degree of CHD.

Objective To evaluate the effect of electroacupuncture (EA) pretreatment on NODlike receptor pyrin domain-containing 3 (NLRP3) in neurons during cerebral ischemia-reperfusion (I/R) in rats.Methods Fifty-four adult male Sprage-Dawley rats,aged 7 weeks,weighing 250-280 g,were randomly divided into 3 groups (n =18 each) using a random number table:sham operation group (group S),group I/R,and EA pretreatment group (group E).Cerebral I/R was induced by occlusion of the right middle cerebral artery for 90 min using a nylon thread inserted into the internal carotid artery and advanced intracranially to block the blood flow,followed by reperfusion.In group E,the acupoint Baihui was stimulated with an electric stimulator (sparse-dense wave,frequency 2 Hz/15 Hz,intensity ≤ 1 mA) for 30 min once a day for 5 consecutive days,and the model of cerebral I/R was established at 24 h after the last stimulation.At 72 h of reperfusion,neurological function was assessed and scored.The rats were then sacrificed,and their brains were removed for determination of cerebral infarct volume (using TTC staining),expression of NLRP3,caspase-1 and interleukin-1beta (IL-1β) in brain tissues (by Western blot),and expression of NLRP3 protein in neurons (by immunofluorescence histochemistry).The percentage of cerebral infarct volume was calculated.Results Compared with group S,the percentage of cerebral infarct volume and neurological scores were significantly decreased,and the expression of NLRP3,caspase-1 and IL-1β in brain tissues was significantly up-regulated in group I/R (P＜0.05).Compared with group I/R,the percentage of cerebral infarct volume and neurological scores were significantly increased,and the expression of NLRP3,caspase-1 and IL-1β in brain tissues was significantly down-regulated ingroup E (P＜0.05).Conclusion The mechanism by which EA pretreatment reduces inflammatory responses during cerebral I/R injury may be related to down-regulation of NLRP3 expression in neurons in rats.

Objective To research the antiviral activity of artesunate (ART) in vitro fighting against both standard laboratory strains and ganciclovir(GCV)-resistance strains of human cytomegalovims(HCMV) and to explore whether fractionation dosage method can obviously enhance the antiviral effect of ART.Methods 1.Cytotoxicity assay to ART was performed by the use of 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide (MTT) colorimetry.The 0％ toxic concentration (TC0) were determined,and median cytotoxic concentration (TC50) was calculated with Probit regression method.2.Antiviral activity assays of ART against HCMV:human embryonic lung fibroblast cells (HELs) were infected with standard laboratory strains and GCV-resistance strains of HCMV,respectively,after which virus was removed and overlays of dulbecco's modified eagle medium(MEM) containing different antiviral drugs were added to the wells.All cells were cultured continuously at 37 ℃ in a 50 mL/L CO2 humidified atmosphere for 7-10 days and the cytopathic effect (CPE) was observed under a microscope.When the degree of CPE was clear (+ + +-+ + + +),the values of absorbency at 490 nm of all cell wells were measured by MTT colorimetry.The cell survival rate (CSR)and drug inhibitory rate (IR) for HCMV were calculated.By Probit regression method,the median inhibitory concentration (IC50) of 2 drugs was calculated respectively.3.To explore whether fractionation dosage method could obviously enhance the antiviral effect of ART against HCMV,the experiment was divided into 3 groups and compared with GCV group,respectively:Group 1:ART antiviral compounds were added to cell layers by one dosage.Group 2:Total drug dosage was divided into 3 parts,and each part was added to cell layers once a day for 3 days.Group 3:Total antiviral compounds were divided into 6 and delivery 2 times a day.The values of absorbency at 490 nm of all cell wells were measured by MTT colorimetry.The CSR and viral inhibitory rates were calculated.All data were statistically analyzed by One-Way ANOVA analyzing using SPSS 18.0 statistical software.P value of ＜0.05 was considered to indicate statistical significance.Results 1.Cytotoxicity assay showed that cytotoxicity was not found in the relevant range of ART concentrations under 62.5 μmol/L.TC0 and TC50 value of ART were 62.5 μmol/L and 171.7 μmol/L.2.In concentration of 5 μmol/L,15 μmol/L and 30 μmol/L,ART and GCV could obviously inhibit growth of HCMV AD169 strains.There was no significant difference between them.The value of GCV IC50 was 3.49μmol/L,and the value of ART IC50 was 2.17 μmol/L.Treatment index (TI) of ART was 28.8,and GCV was 716.3.ART could still obviously inhibit growth of HCMV resistant strains,but GCV couldn't.Differences between them were statistically significant.The value of GCV IC50 to HCMV resistant strains was 44.4 μmol/L,and the value of ART IC50 was 2.5 μmol/L.3.Fractionation dosage method (2 times a day) of ART could improve the inhibition rate of virus significantly compared to that used once a day and single dose method.Difference was statistically significant(P ＜ 0.01).GCV delivered as the same method had little different changes in virus suppression ratio(P ＞ 0.05).Conclusions 1.Cytotoxicity was not found in the relevant range of ART concentrations under 62.5 μmol/L.2.ART could obviously inhibit growth of HCMV resistant strains and standard laboratory strains.3.Fractionation dosage method (2 times a day) of ART could improve the inhibition rate of virus significantly compared to that used once a day and single dose method.4.Because the action mode of ART is different from other anti-HCMV drugs,and ART has a high biological activity and fewer side effects,it is expected to become a kind of new antiviral drugs for HCMV infections.
