Objective To observe the influence of Qingwen Baidu decoction (QBD) on serum procalcitonin (PCT) and C-reactive protein (CRP) levels in septic rats and study the mechanism of heat-clearing and detoxifying method for treatment of sepsis. Methods Fifty male Sprague-Dawley (SD) rats were randomly divided into control group (n=5), model group (n=25), and heat-clearing and detoxifying experimental group (experimental group, n=20). The septic model was reproduced by intra-peritoneal injection of lipopolysaccharide (LPS, 5 mg/kg). In control group, an equal volume of normal saline was given. After modeling for 2 hours, the heat-clearing and detoxifying experimental group received QBD the first time (composition of the decoction: Gypsum Fibrosum Recens 30 g, Rehmanniae Radix 10 g, Bubali Cornu 15 g, Coptidis Rhizoma 4 g, Gardeniae Fructus 5 g, Platycodonis Radix 5 g, Scutellariae Radix 5 g, Anemarrhenae Rhizoma 5 g, Paeoniae Radix Rubra 5 g, Scrophulariae Radix 5 g, Forsythiae Fructus 5 g, Glycyrrhizae Radix 5 g, Moutan Cortex 5 g, Lophatheri Herba 5 g) by gavage (0.01 mL/g); the rest administration time was 08:00 to 09:00, once a day. The rats in model group were given an equal volume of warm water by gavage. At different time points after modeling, the blood of 5 rats in control group, model group, and experimental group was collected from the abdominal aorta. The serum PCT and CRP levels were tested by the enzyme linked immunosorbent assay (ELISA), and the pathological changes in lung and intestinal tissue were observed under a light microscope. Results Compared with the control group, the PCT level of the model group after modeling for 2 hours was significantly increased (ng/L:332.32±22.85 vs. 70.46±3.18, P<0.01), this situation continued until 72 hours after modeling. CRP level in the comparison between the control and model groups did not have statistical significant difference at 2, 8, and 48 hours after modeling (all P > 0.05). The level of CRP in model group was lower than that of control group at 24 hours and 72 hours after modeling (μg/L:281.34±32.81, 237.84±41.42 vs. 350.09±56.67, P<0.05 and P<0.01). There were no statistically significant differences in PCT levels between model group and experimental group after modeling for 8 hours and 24 hours (both P > 0.05). The PCT level of experimental group was significantly lower than that of model group beginning from 48 hours after modeling (ng/L: 321.57±28.00 vs. 358.12±10.14, P < 0.05), and this situation continued until 72 hours after modeling (ng/L: 269.50±49.10 vs. 347.69±26.90, P <0.05). The CRP level of experimental group was significantly lower than that of model group beginning from 8 hours after modeling (μg/L:232.73±13.29 vs. 335.35±53.78, P<0.05), this statistical significant difference between the two groups persisted until 72 hours after modeling (μg/L:177.31±6.70 vs. 237.84±41.42, P<0.05). Compared to those in the model group, the lung tissue inflammatory cell infiltration, the intestinal mucosal inflammation and interstitial edema were milder in the experimental group. Conclusion Heat-clearing and detoxifying therapy can effectively reduce the serum PCT and CRP levels of septic rats induced by LPS, and it can alleviate the infiltration of inflammatory cells in lung tissues so as to play a role in protection of tissue organ.

Objective To observe the lung protective effect of Tongfu Xiefei method (TFXF) in rats with sepsis, and to discuss its possible mechanism.Methods Forty-two Sprague-Dawley (SD) rats were randomly divided into blank control group (n = 6), model group (n = 18) and TFXF group (n = 18). Sepsis model was reproduced by cecal ligation and puncture (CLP) in rats of model group and TFXF group. After the reproduction of sepsis model, rats in TFXF group received Tongfu Xiefei granules 0.01 mL/g by gavge, while those in model group were given equal dose of normal saline by the same way. The rats in blank control group received no treatment. At 3, 6, 12 hours after CLP, abdominal aorta blood was collected for blood gas analysis and inferior vena cava blood was collected for determination of the concentrations of tumor necrosis factor-α (TNF-α) and interleukin-6 (IL-6). Bronchoalveolar lavage fluid (BALF) was collected for measurement of concentrations of total protein (TP), total phospholipid (TPL), and desaturated phosphatidyl choline (DSPC). The ratio of wet/dry lung weight ratio (W/D) was measured, and malondialdehyde (MDA) and myeloperoxidase (MPO) in lung tissues were determined. The pathologic changes in their lungs were observed with light microscopy.Results Compared with those in blank control group, the levels of pH value, arterial oxygen partial pressure (PaO2), HCO3-, base excess (BE) were lowered, and partial pressure of carbon dioxide of arterial blood (PaCO2) was increased in model group. The serum concentrations of TNF-α and IL-6 were gradually increased after the reproduction of sepsis model. Compared with those in blank control group, the levels of TP, TPL, and DSPC/TPL in model group were decreased, while the levels of W/D, MDA and MPO were increased. Compared with those in model group, pH value was elevated in TFXF group at 3 hours (7.27±0.04 vs. 7.18±0.07,P < 0.05). PaO2 (mmHg, 1 mmHg = 0.133 kPa) was improved at 3, 6, 12 hours (3 hours: 128.00±16.05 vs. 106.78±10.73, 6 hours: 98.46±15.97 vs. 72.80±16.33, 12 hours: 90.70±9.31 vs. 74.28±12.19, allP < 0.05). The serum concentrations of TNF-α (ng/L) in TFXF group were significantly lower than those in model group at 12 hours (508.20±94.08 vs. 756.60±138.77,P < 0.05), and the serum concentrations of IL-6 (ng/L) in TFXF group were significantly lower than those in model group at 6 hours and 12 hours (6 hours: 687.80±35.00 vs. 849.40±148.28, 12 hours: 728.80±214.41 vs. 917.00±245.96, bothP < 0.05). Compared with those of model group, the levels of TP (g/L) in BALF in TFXF group were significantly decreased at 12 hours (1.01±0.23 vs. 1.60±0.47,P < 0.05), and the levels of TPL (mg/L) in TFXF group were significantly increased at 12 hours (86.40±11.33 vs. 62.40±16.33,P < 0.05). The levels of DSPC/TPL in TFXF group were significantly higher than those in model group at 6 hours and 12 hours (6 hours: 0.58±0.13 vs. 0.38±0.10, 12 hours: 0.45±0.13 vs. 0.24±0.07, bothP < 0.05). The levels of W/D in TFXF group were significantly higher than those in model group at 3 hours (3.84±0.25 vs. 2.99±0.50,P < 0.01), but lower than those in model group at 12 hours (3.21±0.53 vs. 4.89±1.14,P < 0.05). The levels of MDA (nmol/mg) in TFXF group were significantly lower than those in model group at 6 hours and 12 hours (6 hours: 4.04±2.58 vs. 8.89±2.61, 12 hours: 11.31±3.60 vs. 20.60±8.10, bothP < 0.05), while the levels of MPO (U/g) in TFXF group were lower than those in model group at 12 hours (4.79±0.66 vs. 7.22±1.76,P < 0.05). Compared with model group, the lungs in TFXF group showed less morphological changes under light microscopy, such as pulmonary edema, congestion, effusion and fibrosis.Conclusions The method of Tongfu Xiefei may improve hypoxemia and metabolic acidosis, alleviate lung edema and ameliorate pulmonary pathological changes in rat sepsis model. Tongfu Xiefei method shows a protective effect in sepsis by the way of reducing peroxidative damage, inhibiting the release of proinflammatory factors and abating degradation of lung surfactant.

Objective To observe the effect of Sini decoction on inflammatory response and immune function in septic rats and to discuss its possible mechanism.Methods 66 Sprague-Dawley (SD) rats were randomly divided into normal control group (n=6),model group (n=30),and Sini decoction group (n=30).Septic model was reproduced by intraperitoneal injection of lipopolysaccharide (LPS,5 mg/kg).After the reproduction of sepsis,rats in Sini decoction group received Sini decoction (5 g/kg) by gavage,while those in model group were given equal dose of normal saline in the same way.Rats in normal control group did not receive any treatment.Blood was collected via eye sockets at 2,12,24,48,72 hours after LPS administration,then the rats were sacrificed.The concentrations of inflammatory mediators,such as interleukin (IL-1,IL-6,IL-10),tumor necrosis factor-α (TNF-α),and the expression level of monocyte human leukocyte antigen-DR (HLA-DR) were determined with enzyme linked immunosorbent assay (ELISA),and the pathological changes in intestinal mucosa were observed under electron microscope.Results The concentration of IL-1 (ng/L) at 2 hours in model group was gradually increased and peaked at 48 hours (4.07 ± 0.10),and then gradually decreased,while the IL-1 level in Sini decoction group peaked at 12 hours (2.98 ± 0.12) followed by a gradual decrease.IL-6 (ng/L) in model and Sini decoction groups peaked twice at 12 hours (91.39 ± 1.55,73.00 ± 2.38) and 48 hours (82.51 ± 1.49,64.68 ± 1.68) respectively.IL-10 (ng/L) in model group gradually decreased after peaking at 2 hours (86.66 ± 6.12),and that in Sini decoction decreased at 12 hours (71.61 ± 2.35) followed by an increasing tendency,and approached normal level at 48 hours (109.09 ±4.77 vs.124.01 ± 7.89,P＞0.05).TNF-α (ng/L) in model group was gradually increased and peaked at 48 hours (83.37 ±3.79),and that in Sini decoction peaked at 12 hours (48.52 ± 1.21),and decreased to normal level at 72 hours (18.59 ± 1.97 vs.15.50 ± 2.68,P＞0.05).During the course of the experiment,as compared with those of the model group,level of IL-1,IL-6,and TNF-α were significantly lower at all time points in Sini decoction group,and IL-10was significantly higher.The expression level of HLA-DR (μg/L) in model and Sini decoction groups peaked at 2 hours (4.86 ± 0.15,4.85 ± 0.17),and then gradually lowered.HLA-DR expression μg/L) at 48 hours and 72 hours in Sini decoction group was significantly lower than that in model group (48 hours:4.21 ± 0.12 vs.2.74 ± 0.16,72 hours:3.80 ± 0.09 vs.2.27 ± 0.12,both P＜0.01).Pathological study of intestinal mucosa showed that the intestinal mucosa were infiltrated significandy by inflammatory cells,and villi were damaged severely in both model group and Sini decoction group at 2 hours after LPS challenge.Infiltration of inflammatory cells in Sini decoction group was less intense after 12 hours,and the intestine villi repair was more obvious compared with model group.Conclusion Sini decoction could regulate systemic inflammatory response,and promote the repair of intestinal mucosa,the intestinal function and the immune status of septic rats.

Objective To confirm the effects of statin therapy on mortality of patients with acute lung injury/acute respiratory distress syndrome (ALI/ARDS). Methods PubMed/Medline, Embase, Web of Science andCochrane Central Register of Controlled Trials were searched for articles using the terms acute lung injury, ALI,acute respiratory distress syndrome, ARDS, statin, simvastatin and rosuvastatin updated to November 17,2015. Randomized controlled trial (RCT) or observational cohort studies investigating the effects of statin therapy onmortality in patients with ALI or ARDS were all identified, without date or language restriction. The control group wasgiven conventional treatment, while the experimental group was treated with statins additionally. The primary outcomewas in-hospital mortality. Meanwhile, ventilator-free day, intensive care unit (ICU)-free day, ICU length of stay (LOS)and ICU mortality were also analyzed. RevMan 5.2 and STATA 13 software were used for systematic review and Metaanalysis, and funnel plot was used to analyze the publication bias. Results A total of five trials including threerandomized controlled trials and two observational studies were included. Among 1636 patients enrolled in the study,there were 739 patients in experimental group, and 897 in control group. It was shown by Meta analysis that there was nosignificant difference in in-hospital mortality between experimental group and control group [relative risk (RR) = 0.96,95% confidence interval (95%CI) = 0.79-1.15, P = 0.63]. The subgroup analysis based on RCT and cohort study, or thesubgroup analysis of different statins showed that there was no significant difference in in-hospital mortality betweenthe experimental group and the control group (both P > 0.05). There were no significant differences in ventilator-freedays [mean difference (MD) = 1.41, 95%CI = -0.32-3.13, P = 0.11], ICU-free days (MD = -0.23, 95%CI = -1.61-1.15,P = 0.75), ICU length of stay (MD = -1.03, 95%CI = -6.55-4.50, P = 0.72), or ICU mortality (RR = 0.88, 95%CI =0.68-1.14, P = 0.33) between the experimental group and the control group. It was shown by funnel plot that there was nopublication bias in in-hospital mortality. Conclusion The systematic review and meta-analysis suggests that statin may not be associated with a significant reduction in mortality, ventilator-free day, ICU-free day and ICU length of stayin patients with ALI/ARDS.

Objective: To investigate the epidemiological and etiological characteristics of viral diarrhea among children under 5 years of age in Shaoxing City, Zhejiang Province, so as to provide insights into management of viral diarrhea. Methods: The surveillance data on viral diarrhea among children under 5 years of age in Shaoxing City from 2019 to 2022 were collected, including demographics and stool testing results. The epidemiological and etiological characteristics of viral diarrhea were analyzed using a descriptive epidemiological method. Results: A total of 763 diarrheal children under 5 years of age were reported in Shaoxing City from 2019 to 2022, and 236 children were tested positive for virus (30.93%). The detection of virus was 49.01%, 31.61%, 20.43% and 21.89% from 2019 to 2022, which appeared an overall tendency towards a decline (P<0.05). The incidence of viral diarrhea peaked from November to March of the next year and from May to July, and the detection of virus was lower among children with diarrhea living in urban areas (Yuecheng District, Keqiao District and Shangyu District) than among those in suburb areas (Zhuji City, Shengzhou City and Xinchang County) (30.22% vs. 52.00%, P<0.05). There were 206 children tested positive for a single virus, and the detection rates of rotavirus (RV), enteric adenovirus (EAdV), norovirus (NoV), and sapovirus (SaV) were 9.57%, 8.91%, 8.39%, and 0.13%, respectively. There were 25 children with virus co-infections, and the positive rates of EAdV and NoV, RV and EAdV and RV and NoV co-infections were 1.31%, 1.18% and 0.79%, respectively. There were 5 children with triple infections of RV, EAdV and NoV (0.66%). The highest detection of EAdV was seen in April, the highest detection of RV and NoV was seen in January, while SaV was only detected in April. Conclusion The incidence of viral diarrhea among children under 5 years of age peaked in winter and spring in Shaoxing City from 2019 to 2022, and the cases predominantly occurred in urban areas. The detection of virus appeared an overall tendency towards a decline, with high detection of RV, EAdV and NoV.

AIM: To explore the protective effect of curcumin on high glucose-induced decrease in contraction of isolated rat aortic rings, and to elucidate its underlying mechanism. METHODS: The thoracic aortic rings with endothelium of male Sprague-Dawley rats were mounted on a bath system. Isometric contractions of aortic rings were measured. HO activity was also evaluated. RESULTS: (1)Four hours after incubated with 44 mmol/L of glucose (high glucose),the vascular contraction responses to phenylephrine (PE) decreased compared to control group (containing 11 mmol/L of glucose). (2)Coincubation with curcumin (3×10~(-11)-3×10~(-10) mol/L) and high glucose,the high glucose-induced decrease in contraction responses to PE of arteries was partly inhibited. (3)Four hours after incubation with curcumin,the HO activity in thoracic aorta increased. ZnPP,an inhibitor of HO-1,completely abrogated the protection effect of curcumin. (4)Methylene blue,an inhibitor of guanylate cyclase (GC),partly abolished the protective effect of curcumin. CONCLUSION: Curcumin prevents the high glucose-induced decrease in contraction responses to PE in intact aortic rings. The mechanism might be mainly involved in the activation of HO-1 and GC.

Objective Investigate the prognosis of patients undergoing liver transplantation (LT) for end-stage autoirnmune liver disease (ALD).Method The clinical data of 45 patients with endstage ALD undergoing LT from April 2001 to March 2015 in the first affiliated hospital of Zhejiang University were analyzed retrospectively.The postoperative cumulative survival rate of the recipients was calculated,and the causes of death were analyzed.The postoperative rejections,new onset viral hepatitis and ALD recurrence were also analyzed.Result In 45 ALD recipients,33 cases survived and the postoperative 5-year cumulative survival rate was 78.8％.Causes for 12 dead cases were mnultiple organ failure,liver graft failure,respiratory complications,hemorrhage and hepatic artery embolization.In 45 ALD recipients,6 cases suffered rejection after operation with the incidence bing 13.3％.One case suffered new onset hepatitis B infection 8 years after opcration.One recipient suffered primary disease (primary biliary cirrhosis) recurrence 2 years after operation,and 1 recipient with primary disease (primary sclerosing cholangitis) developed into overlap syndrome.They all survived for a long term after active treatments.Conclusion Most LT recipients with endstage ALD can obtain a long term survival.Attentions should be paid to the immunosuppressive regimens in early period after LT,prevention of infection,rejection and postoperative new onset viral hepatitis,and timely diagnosis of primary disease recurrence.
