ABSTRACT
Acute lung injury (ALI) is a common clinical critical respiratory disease. At present, the mechanism of the disease has not been fully elucidated, there is a lack of specific drugs in clinical practice and the mortality rate is high, which is a difficult problem in the medical field. In recent years, traditional Chinese medicine has exerted its unique advantages and efficacy in the prevention and treatment of ALI, which has aroused the attention of domestic and foreign scholars. Based on the theory of "Wei Qi Ying Xue", this paper discusses the current research status of prevention and treatment of ALI by traditional Chinese medicine, and analyzes its pathogenesis, clinical manifestations and corresponding analysis with TCM syndrome. According to the angle of "Wei Qi Ying Xue", the progress of syndrome differentiation and treatment is highly consistent with immune response, inflammatory response, oxidative stress and apoptosis, in order to find new ideas and medication for the prevention and treatment of ALI with integrated traditional Chinese and Western medicine.
ABSTRACT
Objective:To study the value of neutrophil-to-lymphocyte ratio (NLR) and platelet-to-lymphocyte ratio (PLR) in diagnosing severe Mycoplasma pneumoniae pneumonia (MPP).Methods:A total of 616 cases of MPP patients in the Children′s Hospital of Soochow University from January 2015 to December 2017 were retrospectively analyzed.During the same period, 100 healthy children were selected as the healthy control group.NLR and PLR between MPP group and healthy control group, and those between severe MPP group and ordinary MPP group were compared by t test or rank sum test.Risk factors for severe MPP were identified.Receiver operating characteristic(ROC) curves were plotted to identify the cut-off point of NLR and PLR in distinguishing MPP from healthy subjects. Results:(1)The median of white blood cell count (WBC), neutrophil count (N), platelet count (PLT), NLR, PLR, immunoglobulin M (IgM) and the median percentage of CD3 -CD 19+ , CD 19+ CD 23+ in MPP group were significantly higher than those in healthy control group(8.36×10 9/L vs.7.49×10 9/L, 4.41×10 9/L vs.3.11×10 9/L, 340.92×10 9/L vs.234.00×10 9/L, 1.70 vs.0.91, 112.99 vs.70.34, 1.33 g/L vs.1.29 g/L, 20.95% vs.17.10%, 11.25% vs.9.70%), whereas the median of lymphocyte count (L), IgA and the median percentage of CD3 + , CD3 + CD8 + , and CD3 -CD +(16+ 56) were significantly lower(2.64×10 9/L vs.3.37×10 9/L, 0.86 g/L vs.1.30 g/L, 64.55% vs.68.00%, 23.65% vs.24.90%, 10.50% vs.12.20%)( Z=-3.074, -2.413, -2.972, -1.357, -1.863, -2.251, -4.282, -3.420, -2.221, -4.181, -2.784, -2.024, -2.791, all P<0.05). (2)The median of N, NLR, PLR, IgA, IgG, IgM and the average of percentage of CD3 + , CD3 + CD8 + in severe MPP group were significantly higher than those in ordinary MPP group[5.18×10 9/L vs.3.52×10 9/L, 2.39 vs.1.03, 149.32 vs.94.23, 1.29 g/L vs.0.71 g/L, 9.63 g/L vs.8.19 g/L, 1.40 g/L vs.1.29 g/L, (65.53±9.75)% vs.(62.81±9.89)%, (25.35±6.65)% vs.(23.38±6.91)%], whereas the median of L, the median percentage of CD3 -CD 19+ , and CD 19+ CD 23+ were significantly lower than those of ordinary MPP group(2.02×10 9/L vs.3.25×10 9/L, 17.40% vs.21.50%, 9.00% vs.11.70%)( Z/ t=-7.807, -11.313, -10.452, -8.819, -6.162, -3.047, -3.128, -3.270, -9.402, -5.191, -5.214, all P<0.05).

Conclusions:NLR and PLR can be served as independent influencing factors for severe MPP, showing the diagnostic potential in severe MPP.
ABSTRACT
Pulmonary fibrosis (PF) is a chronic progressive interstitial lung disease. The pathogenesis of PF is not yet clear. The two anti fibrosis drugs approved for IPF treatment, nidanib and pirfenidone, have been proved to reduce the decline of pulmonary function of pF, but both have side effects. So far, there is no obvious and effective treatment to prevent the progress of pF. Therefore, this review focuses on the different cells, molecular mechanisms involved in PF and the current treatment progress of PF, so as to provide theoretical support for a better understanding of these cells, molecular mechanisms and drug development and application in PF.
ABSTRACT
Objective:To explore the effect of CDIO (conceive, design, implement, operate) model workshop training on the training of new nurses in the operating room.Methods:Forty-two nurses with standardized training were selected as the research objects, and they were randomly divided into two groups: observation group ( n=21) and control group ( n=21). The control group used the traditional training method in the operating room, and the observation group used the workshop training based on the CDIO model. SPSS 17.0 was used to statistically analyze the operation skill scores and case scores after training. The measurement data is expressed by (mean±standard deviation), the independent sample t test is used for comparison between the two groups, and the chi-square test is used for the comparison of counting data. Results:After the training, the scores of operating room knowledge assessment of the two groups were (72.31±2.16) points and (73.61±2.18) points respectively, with statistical significance ( P<0.05); the operation skill scores of observation group were (7.42±0.13) points, which were higher than those of the control group (6.62±0.11) points, and the disposal scores of observation group after operation were (7.12±0.20) points, which were higher than those of the control group (6.27±0.16) points, with statistical significance ( P<0.05); the professional quality scores of observation group were (7.41±0.25) points, which were higher than those of the control group (6.55±0.22) points; the adaptability scores of observation group were (7.06±0.22), which were higher than those of control group (6.35±0.21) points, with statistical significance ( P<0.05). Conclusion:The workshop training based on the CDIO model is effective for the training of nurses in the operating room, and the combined application effect is better than the effect of the traditional teaching model, especially for the improvement of practical skills.

ABSTRACT
Objective To observe the molecular mechanism of adaptive response of the kidney and skeleton and brain issues in the high altitude hypoxia; To discuss the unity of yin and yang oscillation relationship of kidney and brain marrow.Methods SPF KM mice were randomly divided into control group and model group according to random number table method. Mice in the model group were exposed to high altitude hypoxia cabin for successive 21 d. On the 22nd day, mice got out of the cabin and their body weight was measured, and then they were put to death through eyeball blood sampling. The activities of lactic LDH and Na+-K+-ATPase in brain tissue were detected by spectrophotometric colorimetry. The PFK activities of brain and skeletal muscle were detected by ELISA. Meanwhile the contents of EPO and EPOR in the kidney were measured by ELISA. The mRNA expressions of HIF-1α and AQP-4 in brain were assessed by RT-PCR. At the same time, the protein expressions of HIF-1α and AQP-1 in brain and the protein expression of Mb in skeletal muscle were detected by Western blot.Results Compared with the normal group, the LDH and PFK in brain tissue and the content of EPO in kidney tissue were all raised in the model group(P<0.05). Meanwhile the mRNA expressions of HIF-1α and AQP-4 and the protein expressions of HIF-1α and AQP-1 in brain were all increased in the mice from the model group; the activities of PFK and the protein expression of Mb in skeletal muscle were also raised in the model group. But the activity of Na+-K+-ATPase in brain tissue and the content of EPOR in kidney tissue both decreased in the model group (P<0.05,P<0.01).Conclusion Adaptive response and the unity of yin and yang oscillation relationship between kidney, skeleton and brain tissue happen in high altitude hypoxia.
ABSTRACT
Objective To explore the intervention effect of active fraction of Angelica Sinensis Radix in mice under high altitude hypoxia condition. Methods Totally 72 healthy SPF mice were randomly divided into control group (K), model group (M), Rhodiola rosea group, and active fraction of Angelica Sinensis Radix groups (B, C, X). The mice were administerted corresponding treatment by gavage for 21 days. Control mice were given normal saline in same volume. From the 8th day, all mice excepted control mice were exposed to high altitude hypoxia cabin after 0.5 hour gavage treament. On the 22nd day, after got out of the cabin and their body weight were measured, mice were put to death through eyeball blood sampling to prepare splenic lymphocyte suspension. The proliferation and transformation capacities of lymphocyte cell and killing activity of NK cells were detected by MTT. The content of IL-2 in the serum of mice in each group were detected by ELISA. Results Compared with the control group, the body weight of mice, the proliferation and transformation capacities of lymphocyte cell, the killing activity of NK cells, and the content of IL-2 were all significantly decreased (P<0.05, P<0.01). Experiment tests showed that the proliferation and transformation abilities of lymphocyte cell and the killing activity of NK cells were all increased in the mice of group B, C, and X compared with those of the model group (P<0.05, P<0.01). The stimulate index of lymphocyte cell was raised after X intervention compared with those of the model group (P<0.05). The content of IL-2 in the serum was enhanced after intervention of active fraction C and X of Angelica Sinensis Radix compared with those of the model group (P<0.05, P<0.01). Conclusion Active fraction of Angelica Sinensis Radix shows increasing immunological function of mice exposed to hypoxia.

ABSTRACT
OBJECTIVE@#To determine the effect of Tanshinone IIA (TanIIA) on the phosphory-lated NMDA receptor 1 at Serine 897 site (phospho-NR1 S897) and intracellular free calcium concentration ([Ca(2+)](i)) in neonatal SD rats with hypoxic ischemic brain damage (HIBD), and to explore the neuroprotective mechanism of TanIIA in HIBD.@*METHODS@#Neonatal SD rats were randomly divided into a normal control, and an HIBD and TanIIA+HIBD group. Rice-Vannucci method was used for HIBD animal model. Time points were: 3, 6, 12, and 24 h after HIBD (n=10 in each group at each time point). TanIIA was intraperitoneally given at 1 μg/g every 12 h. Fura-2AM was used to mark the fluorescent calcium probe and [Ca(2+)](i) was measured by a Hitachi F-4500 Fluorescence Spectrophometer. Fluorescent immunohisotichemical study was used for the expression of phospho-NR1 S897.@*RESULTS@#(1) Compared with the normal control group, both the [Ca(2+)](i) absolute number and ipsi-/contra-lateral ratio were increased at each time point with statistical significance (P<0.05). Compared with the HIBD group, the [Ca(2+)](i) in the HIBD+ TanIIA group was decreased at each time point. At 24 h after HIBD, the ipsi-/contra-lateral ratio of HIBD+ TanIIA group was 24.9% less than that of HIBD group with statistical significance (P<0.05). (2) In the normal control group, abundant phospho-NR1 S897 positive cells were nicely distributed in the cortex. Compared with the normal control group, at each time point, both the absolute number of phospho-NR1 S897 positive cells and the fluorescent intensity of phospho-NR1 S897 in the ipsilateral cortex of the HIBD group were decreased with statistical significance (P<0.05). Compared with the HIBD group, both the absolute number of phospho-NR1 S897 positive cells and the fluorescent intensity of phospho-NR1 S897 in the ipsilateral cortex of HIBD+ TanIIA were increased. There was significant difference at 3 and 12 h after the HIBD (P<0.05).@*CONCLUSION@#TanIIA reduced the HIBD-caused down-regulation of phospho-NR1 S897 and the HIBD-caused [Ca(2+)](i) elevation in the cortex. The neuroprotective effect of TanIIA may be related to influencing NMDA receptor expression and decreasing intracellular free calcium aggregation.

Objective To investigate the prevalence, clinical characteristics and antibiotic resistance of Haemophilus influenzae (HI) in children with acute respiratory tract infection in Suzhou. Methods Data of sputum culture of 3 167 hospitalized childhood patients with acute respiratory tract infection from January 2006 to December 2007 were collected. The incidence of positive HI and the rate of resistance to different antibiotics were calculated and beta-lactamases of the strains were detected. Results About 4.4% of total 3 167 eases were infected with HI. The infection rate was related with season and sex, more frequent between February and June, more common in boys than girls. Children younger than three years old were likely to be infected by HI, eompared with other age groups. The beta-lactamase positive rate of HI was 31.4%. The resistance rates to ampicillin, SMZ + TMP, chloramphenicol, cefaclor, ceftazidime, tetracycline and ampicillin/sulbactam were 29.6% ～ 31.9%, 66.2% -73.9%, 19.7% ～ 15.9%, 2.8% ～ 14.5%, 2.8% ～0、 28.2% ～ 2.9% and 4.2% ～ 1.4% respectively. Isolates resistance to cefuroxime、 ceftriaxone、 imipenem、azithromycin and ciprofloxacin were not found. Conclusions The infection of HI in children with actue respiratory tract infection is closely related with season and sex in Suzhou. Children younger than three years old are at high risk. The beta-lactamase positive rate of HI was high and increased rapidly. Resistance rate to azithromycin, SMZ + TMP and chloramphenicol was high, some isolates were resistant to the second, third generation of cephalosporin. Monitoring the antibiotic resistance of H! should be emphasized.
