ObjectiveTo compare the effects of different tidal volumes and positive end expiratory pressures （PEEPs） during mechanical ventilation on the cardiac output of pigs measured by pulmonary artery catheter， transpulmonary thermodilution and pulse contour analysis， and to explore their consistency in cardiac output determination. MethodsTwelve experimental pigs were selected and randomly divided into 3 groups， with 4 pigs in each. Cardiac output was measured by different methods， control group by pulmonary artery catheter， group A by transpulmonary thermodilution and group B by pulse contour analysis. Then we compared the effects of different tidal volumes and PEEPs on the cardiac output of pigs and to explore the consistency. The correlation coefficient between pulse contour analysis and pulmonary artery catheter was r=0.754， and they were positively correlated. The correlation coefficient between transpulmonary thermodilution and pulmonary artery catheter was r=0.771， and they were positively correlated. In determining cardiac output， pulse contour analysis was consistent with pulmonary artery catheter， with a relative error of 13.5% between them； transpulmonary thermodilution was consistent with pulmonary artery catheter， with a relative error of 12.9% between them. The cardiac output decreased significantly along with the increase of tidal volumes or PEEPs and the differences were statistically significant （P<0.05） ConclusionPulmonary artery catheter， transpulmonary thermodilution and pulse contour analysis are well consistent with each other in measuring the cardiac output of pigs. The pigs’cardiac output gradually decreased along with the increase of tidal volumes or PEEPs during mechanical ventilation.

This paper summarized the clinical experience of professor XUAN Guowei in treating non-specific vulvitis from spleen. He believes that the core pathological mechanism of this condition lies in spleen deficiency and dampness accumulation； in the acute phase， spleen deficiency is taken as the root cause and damp-heat toxins accumulated in the vulva as the key； in the chronic phase， spleen deficiency and dampness accumulation is the main pathogenesis， accompanied by kidney deficiency. In clinical practice， the basic method of fortifying spleen and eliminating dampness is used， and self-made Jianpi Shenshi Formula （健脾渗湿方） is recommended as the basic prescription. During the acute phase， the medicinals of clearing heat and resolving toxins are supplemented， while during the chronic phase， medicinals aims at fortifying the spleen and consolidating the kidneys， boosting qi and nourishing yin are added. Simultaneously， there is an emphasis on integrated treatment combining internal and external treatment， and both Chinese and western medicine， and he highlights the importance of daily prevention and care for patients. Additionally， external used Xiaoyan Zhiyang Cream （消炎止痒霜） is created.

Objective:To investigate the effect and mechanism of the Bushen Jianpi Kaixin formula on the learning and memory ability of Alzheimer's disease (AD) model rats.Method:A total of 72 SPF grade male SD rats were divided into control group, model group, Bushen group, Jianpi group, Kaixin group and Bushen Jianpi Kaixin group according to the random number table method ( n=12 in each group). The rats were intraperitoneally injected with D-galactose once a day for 6 weeks to replicate the model of AD.And the rats in different medication groups were given corresponding administration (Bushen formula: gavage 3.60 g·kg -1·d -1, Jianpi formula: gavage 4.05 g·kg -1·d -1, Kaixin formula: gavage 2.34 g·kg -1·d -1, Bushen Jianpi Kaixin formula: gavage 9.99 g·kg -1·d -1), while rats in control group and model group were treated with equal volume of 0.9% sodium chloride solution once a day for 28 days.The learning and memory ability was tested by Morris water maze.The expressions of phosphoinositide 3-kinase(PI3K), protein kinase B(Akt) and mammalian target of rapamycin(mTOR) in cerebral cortical tissues were detected by immunohistochemistry.The relative mRNA levels of p62 and Beclin in brain cortical tissue were detected by RT-PCR.SPSS 25.0 software was used for data processing, one-way ANOVA was used for inter group comparisons, and LSD test was used for further pairwise comparisons. Results:Morris water maze results showed statistically significant differences in escape latency and the times of crossing platform among the six groups ( F=368.10, 47.43, both P<0.01). The escape latency of Bushen Jianpi Kaixin group((29.30±1.64) s) was shorter than that of model group((55.58±3.23) s) ( P<0.01), the times of crossing platform ((5.17±0.72) times) in Bushen Jianpi Kaixin group was higher than that of model group (1.50±0.52)time, P<0.01). Compared with the Bushen Jianpi Kaixin group, the escape latencies of Bushen group, Jianpi group and Kaixin group were longer (all P<0.01), the times of crossing platform in Bushen group was lower ( P<0.01). Immunohistochemical results showed statistically significant differences in the positive protein expression of PI3K, Akt, and mTOR proteins among the six groups ( F=68.52, 22.22, 31.52, all P<0.01). Compared with the model group, the levels of positive protein of PI3K ((0.47±0.15), (0.57±0.12)), Akt ((0.31±0.02), (0.38±0.02)), and mTOR ((0.22±0.18), (0.28±0.11)) in Bushen Jianpi Kaixin group were less (all P<0.01). Compared with the Bushen Jianpi Kaixin group, the levels of positive protein of PI3K and mTOR of Bushen group, Jianpi group and Kaixin group were higher (all P<0.01). RT-PCR results showed statistically significant differences in the relative mRNA levels of Beclin and p62 among all the groups ( F=8.79, 21.01, both P<0.01). The relative mRNA level of Beclin in Bushen Jianpi Kaixin group was higher than that of the model group ((0.97±0.07), (0.64±0.12)), and the relative mRNA level of p62 of Bushen Jianpi Kaixin group was less than that of model group((0.98±0.16), (1.16±0.24))(both P<0.01). The relative mRNA levels of p62 in Bushen group, Jianpi group and Kaixin group were higer than those of Bushen Jianpi Kaixin group (all P<0.05). Conclusion:Bushen Jianpi Kaixin formula can improve cognitive impairment and learning and memory ability in AD model rats.The mechanism may be related to the regulation of PI3K/Akt/mTOR autophagy pathway.The combination prescription is better than the split prescription.

OBJECTIVE：To study the repa ir，anti-inflammatory and analgesic effects of Compound crocodile oil burn ointment on superficial second-degree burned skin. METHODS ：The heated weight was attached to the right depilated skin of guinea pigs for 4 s to induce the model of superficial second-degree burn.

The thick new epidermal layer was found in wound tissue ，and the connective tissue and neovascularization in the dermis increased significantly. In the anti-inflammatory and analgesic experiment ，after intervention of Compound crocodile oil burn ointment ，the degree of ear swelling and the times of writhing decreased significantly （P＜0.05 or P＜0.01）. CONCLUSIONS ：Compound crocodile oil burn ointment shows good skin repair ，anti-inflammatory and analgesic efficacy；the mechanism may be associated with increasing the serum levels of EGF and SOD and reducing the levels of VEGF ， MDA，TNF-α，IL-1.

Objective:To Investigate comprehensive predictive ability of first-trimester complete blood count combined with maternal characteristics for gestational diabetes mellitus (GDM).Methods:From May 2015 to July 2018, 1 412 pregnant women were retrospectively screened at the Fifth People′s Hospital of Shanghai, Fudan University. We recruited 258 women who developed GDM and 1 154 women who had normal glucose level during pregnancy. At the first visit, clinical data and complete blood count result were obtained. GDM prediction models were established through logistic regression analysis of GDM related risk factors and the prediction abilities of each model were compared.Results:Logistic regression analyses identified age, pre-pregnancy body mass index, previous GDM history, family history of diabetes mellitus, the neutrophil-to-lymphocyte ratio, leukocyte, neutrophil, and monocyte counts were significantly independent predictors of GDM. In the entire cohort, the predictive ability of neutrophil and monocyte counts together with maternal basal characteristics model for the development of GDM [areas under the receiver operating characteristic curve (AUC-ROC)=0.809, integrated discrimination improvement (IDI)=0.056, P=0.001] was the best among various models (basal characteristics model, AUC-ROC=0.753; Monocyte count+ basal characteristics model, AUC-ROC=0.764; neutrophil count + basal characteristics model, AUC-ROC=0.775). Similar results obtained by the same way in all pregnant women without previous GDM history. Conclusion:It could improve the prediction of GDM with model incorporated maternal characteristics and first-trimester neutrophil and monocyte counts.

OBJECTIVE: To assess the efficacy and safety of Chinese medicine injection (CMI) for treating acute lung injury/acute respiratory distress syndrome (ALI/ARDS). METHODS: Randomized controlled trials (RCTs) were identified by searching 3 English databases and 4 Chinese databases from their inceptions until February 2019. The Cochrane Handbook was used to evaluate risk of bias in the included studies. Data analysis was conducted using RevMan 5.3.3 software. RESULTS: A total of 19 eligible RCTs involving 1,334 participants was included in this systematic review and meta-analysis. The main meta-analysis showed that CMI combined with conventional therapy (CT) was more effective than CT alone in reducing the acute physiology and chronic health evaluation (APACHE) H score [mean difference (MD): -1.74 points, 95% confidence interval (CI): -2.77 to -0.71, I CONCLUSIONS CMI as an adjuvant therapy showed great potential benefits for the treatment of ALI/ARDS. However, we could not make a definite conclusion due to low quality of included studies and uncertain security. Future studies should focus on improving research design, especially in blindness and placebo. The reporting of adverse events was also needed.

Objective: To explore the relationship between hemoglobin (Hb) level during the first trimester of pregnancy and gestational diabetes mellitus (GDM). Methods: A total of 1 276 participants, who underwent scheduled prenatal examination and normal singleton delivery at the Fifth People's Hospital of Shanghai and Hospital of Intergrated Chinese and Western Medicine in Minhang District, from January 2016 to May 2018 were included. There were 99 cases of GDM (GDM group) and 1 177 cases of normal (control group) pregnant women.Based on the serum Hb level during the first trimester of pregnancy, participants were divided into three groups, 236 cases of low Hb level group (Hb<110 g/L), 868 cases of normal Hb level group (110 g/L≤Hb<130 g/L), and 172 cases of high Hb level group (Hb≥130 g/L). Maternal clinical data were collected, including Hb level during the first trimester of pregnancy, three-point blood glucose (BG) of oral glucose tolerance test (OGTT) and fasting insulin during the second trimester of pregnancy. Homeostasis model assessment of insulin resistance index (HOMA-IR) and homeostasis model assessment of pancreatic β cell function index (HOMA-β) were used to evaluate insulin resistance and pancreatic β cell function. Results: (1) Hb level during the first trimester of pregnancy in GDM group was significantly higher than that in control group [(123±10),(119±11) g/L, P<0.05]. There were no significant difference in gravidity, parity, index of liver and renal function (all P>0.05). (2) Pre-pregnancy body mass index (BMI), 1-hour BG and 2-hour BG of OGTT were significantly increased in the high Hb level group during the first trimester of pregnancy, which were (23±4) kg/m², (7.3±2.0) mmol/L, and (6.5±1.4) mmol/L (P<0.05), respectively. The pre-pregnancy BMI, 1-hour BG and 2-hour BG of the normal or low Hb level group were (22±3) kg/m², (6.7±1.6) mmol/L, (6.1±1.2) mmol/L; (22±3) kg/m², (6.5±1.5) mmol/L, (5.9±1.1) mmol/L, respectively. There were no statistically significant difference in levels of fasting blood glucose, fasting insulin, HOMA-IR and HOMA-β within 3 groups (all P>0.05). (3) In the high Hb level group, prevalence of pregnancy overweight or obesity and GDM were the highest, which were 37.2%(64/172) and 15.1%(26/172), respectively; the differences were statistically significant (all P<0.05). (4) The serum Hb level in the first trimester was positively related with pre-pregnancy BMI (r=0.130, P<0.05), 1-hour BG (r=0.129, P<0.05), 2-hour BG (r=0.134, P<0.05), fasting insulin (r=0.096, P<0.05), and HOMA-IR (r=0.101, P<0.05).Logistic regression indicated that Hb≥130 g/L during the first trimester of pregnancy was an independent risk factor for GDM (OR=2.799, 95%CI: 1.186-6.604; P<0.05). Conclusion The high level of Hb (Hb≥130 g/L) during the first trimester of pregnancy is associated with GDM.

This paper reports a case of a male patient with diabetes for more than 20 years who came to see doctor due to weakness, poor appetite and significantly elevated blood glucose. At first, it was considered that the poor blood glucose control of diabetes was the reason, and the possibility of diabetes related complications already existed. Hospital routine examination indicated a globulin increase and immunologic examination indicated that IgM was mainly increased. Subsequent imageological diagnosis revealed a small amount of bilateral pleural effusion, and after 2 weeks of hypoglycemic treatment, the blood glucose was significantly improved, but the symptoms still existed. In combination with the patient′s laboratory examination, considering the combination of blood system diseases, the hematology department was invited for consultation. Immunoelectrophoresis, bone marrow cytology, and flow cytometry were further conducted, and the patient was diagnosed with Waldenstrom macroglobulinebia. Bortezomib + dexamethasone regimen was given for chemotherapy. Currently, the patient has received 1 course of chemotherapy, and the symptoms of poor appetite were significantly improved. Coexistence of diabetes mellitus and Waldenstrom macroglobulinebia is very rare in clinical practice, and it is easy to be misdiagnosed as a complication of diabetes mellitus, both of which can be manifested as poor appetite, weakness, peripheral neuropathy and other symptoms. When diabetic patients have abnormal immunoglobulin increases and other abnormal test results that cannot be well explained by diabetes, other potential disorders, such as hematological diseases, should be considered to avoid missed diagnosis.

Objective To investigate the threshold values of insulin resistance ( IR) assessed by homeostasis model and the prevalence of IR in elderly people over 60 years old in Minhang district of Shanghai, and to evaluate the relationship between IR and metabolic syndrome ( MS) . Methods A total of 3003 elderly people aged 60 and over in the Jiangchuan community of Minhang District, Shanghai, were recruited, including 1286 males and 1717 females. Blood pressure, waist circumference, BMI, blood routine, serum creatinine, blood lipids, glucose, and fasting insulin were measured in all populations studied. Homeostasis model assessment ( HOMA) was used to estimate IR, and MS, and defined according to three diagnostic criteria including NCEP-ATPIII, IDF, and CDS. Results 75th percentile, 80th percentile and 90th percentile of HOMA values in 268 subjects with normotensive and normal BMI, glucose tolerance were considered as the thresholds of IR. The cut-off values were 2. 78, 3. 01 and 3. 56, respectively. And the prevalence of IR were 50. 0％, 42. 1％, and 27. 2％, respectively. IR level was significantly higher in people with MS. Based on the receiver operating characteristic ( ROC ) curve analysis, HOMA-IR and QUICKI index predicted MS well, and the optimal thresholds for diagnosing MS of HOMA-IR were 3. 17 for NCEP-ATPⅢ, 3. 02 for IDF and 3. 03 for CDS. BMI was the best factor for diagnosing IR among different MS components. Logistic regression analysis showed that gender, WC, BMI, SBP, HDL-C, TG, FBG and WBC were independent risk factors for IR. FBG≥5.84 mmol/L was the most dangerous factor of IR (OR=3.603,P<0.01), followed by WC≥85.4 cm(OR=2.152, P<0.01) and BMI≥24.6 kg/m2(OR=2.150,P<0.01). Conclusion The cut-off values of IR estimated by HOMA and the prevalence of IR were higher in elder subjects than other populations. IR was significantly positively correlated with MS. Excluding the conditions that insulin measurement were affected by external factors, HOMA-IR may predict the risk of MS. The components of MS were relative specific measurements of IR, FBG, BMI and WC were important risk predictors of IR in the elderly.
