BACKGROUND: Superior trunk of brachial plexus nerve is the part where brachial plexus nerve injury occurred easily during the process of delivery.OBJECTIVE: To perform elongation test, stress relaxation and creeping test on superior trunk of brachial plexus nerve of fresh fetal corpses, and to analyze the mechanical characters of elongation and mechanical characters of visco-elasticity.DESIGN: A randomized and controlled experiment, multiple variable analysis.SETTING: Department of Radiology, China-Japan Union Hospital, Jilin University, Department of Engineering Mechanics, Nanling Campus, Jilin niversity.MATERIALS: The specimens were 30 dead and fresh fetuses aged 6.5 to 8 months, including 16 male and 14 female.METHODS: ①After efrosting at ordinary temperature, superior trunk of brachial plexus nerve was taken out, and 100 samples were cut out along the length wise of specimen. 32 samples were used in elongation test, 32 in stress relaxation test and 32 in creeping test and 4 in pre-test. ②Elongation test, stress relaxation test and creeping test were separate and each test was subdivided into 4 groups: male fetus group of 6.5 to 7 months ,male fetus group of over 8 months, female fetus group of 6.5 to 7 months and female etus group of over 8 months, with 8 samples in each group. ③Superior trunk of brachial plexus nerve was performed one-way elongation test ,and destroy load , intensity limit, maximum strain were obtained; Superior trunk of brachial plexus nerve as performed stress relaxation test and creeping test, and data and curve of stress relaxation test and creeping test were obtained. Experimental data were given normalized treatment and normalized stress relaxation function and normalized creeping function and curve were derived. The experimental data were performed regression analysis with one-dimensional linear regression analysis, then regression coefficient was obtained and experimental curve was fitted.MAIN OUTCOME MEASURES: Mechanical characters of elongation and mechanical characters of visco-elasticity of superior trunk of brachial plexus nerve.RESULTS: ①Destroy load, intensity limit and maximum strain of superior trunk of brachial plexus nerve were all less in fetus group of 6.5 to 7 months than in the fetus group of over 8 months (P ＜ 0.05). There was no significant difference of mechanical characters of elongation among brachial plexus nerves between male and female (P ＞ 0.05). ② 7 200 s creeping quantity was larger in female fetus group of over 8 months than in the male fetus group of over 8 months [(10.2±1.1)%, (7.2±1.08)% ,P ＜ 0.05].7 200 s creeping quantity was basically close in female fetus group of 6.5 to 7 months group to male fetus group of 6.5 to 7 months [(16.7± 1.6)%,(15.1±1.2)%,P ＞ 0.05]. ③ 7 200 s stress relaxation quantity was basically similar in male fetus group of over 8 months to female fetus group of over 8 months (P ＞ 0.05). 7 200 s stress relaxation quantity was larger in male fetus group of 6.5 to 7 months than in female fetus group of 6.5 to 7 months (P ＜ 0.05).CONCLUSION: In the process of delivery, at the same external force, only fewer fetuses with poor ability to resist external force present brachial plexus nerve injury. The individual difference of mechanical characters of elongation of superior trunk of brachial plexus nerve might be caused by heredity, dystrophy and other factors. In addition, at the same strain, the creeping quantity is larger in the female group of small month than in the female group of large month, which might be due to that the development of brachial plexus nerve is not mature in the fetus of small months as that in the fetus of large months.

Objective To explore the clinical effect of Salvianolate for treatment of coagulant function abnormality in patients with septic shock.Methods One hundred and fifty-two septic shock patients admitted to Intensive Care Unit (ICU) of Department of Critical Care Medicine,Liuzhou Municipal Liutie Central Hospital from January 2007 to June 2016 were enrolled,and they were divided into a control group (67 cases) and a Salvianolate group (85 cases) by random number table.In the control group,conventional western medicine treatment was given,while in Salvianolate group,besides conventional treatment,additionally,Salvianolate 200 mg intravenous drip was applied daily for consecutive 10 days.The levels of D-dimer and platelet count (PLT) were examined on the 1st,3rd,7th,10th day after admission;disseminated intravascular coagulation (DIC) incidence and mortality were observed in 10 days after admission in the two groups.Results The levels of D-dimer were significantly lower in the Salvianolate group than those of the control group on 3,7,10 days after admission (mg/L:3 days was 9.14 ± 2.25 vs.18.42 ± 3.15,7 days was 6.71 ± 1.49 vs.14.57 ± 1.81,10 days was 1.01-± 0.20 vs.4.79-± 0.81,all P ＜ 0.01).In both groups,on the first day after admission the level of PLT began to decrease,on the 3th,7th day the levels were lowered significantly,and on the 10th day,the level of PLT was elevated;in the Salvianolate group,the levels of PLT were obviously higher on the 3rd,7th,10th day after admission than those of the control group [PLT (x 109/L) 3 days after admission:67.05-± 7.76 vs.40.97 ± 6.51,7 days:67.24 ± 6.35 vs.32.06 ± 5.13,10 days:90.18 ± 11.42 vs.59.04 ± 6.57,all P ＜0.01].The DIC incidence and mortality were significantly lower in the Salvianolate group than those of the control group [DIC incidence:12.94％ (11/85) vs.38.8％ (26/67),mortality:5.88％ (5/85) vs.29.85％ (20/67),both P ＜0.01].Conclusions Coagulant function abnormality was found in most patients with septic shock.The cause of PLT decreasing is mainly due to micro-vascular thrombosis that consumes a lot of PLT.Early intervention with Salvianolate in such patients can inhibit thrombosis,block the exhaustion of PLT and correct the coagulant function abnormality with certain efficacy in the patients.

Objective To evaluate the effect of cardamonin on acute lung injury induced by hemorrhagic shock and resuscitation (HSR) in rats.Methods Thirty-two male Sprague-Dawley rats,aged 18-24 weeks,weighing 200-250 g,were divided into 4 groups (n =8 each) using a random number table:sham operation group (group Sham);group HSR;cardamonin group (group CA);cardamonin + adenosina A2A receptor antagonist ZM241385 group (group CZM).Bilateral common carotid arteries were only cannulated in group Sham.The left common carotid artery was cannulated for blood-letting until mean arterial pressure was reduced to 35-45 mmHg and maintained at this level for 30 min,and the animals were then resuscitated by infusion of shed blood and normal saline two-fold volume of shed blood to establish HSR model in HSR,CA and CZM groups.ZM241385 5 mg/kg was injected intraperitoneally at 30 min before blood-letting in group CZM,and cardamonin 75 mg/kg was injected intraperitoneally immediately after the beginning of resuscitation in CA and CZM groups.The rats were sacrificed at 2 h after completion of resuscitation,bronchoalveolar lavage fluid (BALF) was collected for determination of neutrophil count,and lungs were removed for microscopic examination of the pathological changes and for determination of wet/dry lung weight ratio (W/D ratio),contents of tumor necrosis factor-alpha (TNF-ct),interleukin-1 (IL-1β) and IL-6 (by enzyme-linked immunosorbent assay) and expression of adenosine A2A receptors in lung tissues (by Western blot).Results Compared with group Sham,the neutrophil count in BALF,W/D ratio and contents of TNF-α,IL-1β and IL-6 were significantly increased,the expression of adenosine A2A receptors was significantly down-regulated in group HSR,and the neutrophil count in BALF and contents of TNF-α and IL-6 were significantly increased (P＜0.05),and no significant changes were found in W/D ratio,content of IL-1β,and expression of adenosine A2A receptors in group CA (P＞0.05).Compared with group HSR,the neutrophil count in BALF,W/D ratio and contents of TNF-α,IL-1β and IL-6 were significantly decreased,the expression of adenosine A2A receptors was significantly up-regulated (P＜0.05),and the pathological changes were significantly attenuated in group CA,and no significant changes were found in the parameters mentioned above in group CZM (P＞0.05).Compared with group CA,the neutrophil count in BALF,W/D ratio and contents of TNF-α,IL-1β and IL-6 were significantly increased,the expression of adenosine A2A receptors was significantly down-regulated (P＜0.05),and the pathological changes were aggravated in group CZM.Conclusion Cardamonin can attenuate acute lung injury induced by HSR in rats,and activated adenosine A2A receptors and inhibited inflammatory responses are involved in the mechanism.

ObjectiveTo explore the impact of Gegen Qinliantang（GQT） on the fecal short-chain fatty acids（SCFAs） metabolism in antibiotic-associated diarrhea（AAD） through targeted metabolomics. MethodA total of 240 SD rats were randomly divided into six groups（n=40， half male and half female）， including blank group， model group， bifidobiogen group（0.15 g·kg^-1）， and GQT high-， medium-， and low-dose groups（10.08， 5.04， 2.52 g·kg^-1）， except for the blank group， clindamycin（250 mg·kg^-1） was given to all groups by gavage for modeling every day for 7 d. After successful modeling， each administered group was gavaged with the corresponding dose of the drug， and the blank and model groups were gavaged with an equal volume of normal saline solution， 1 time/d， for 14 d. At 0， 3， 7， 14 d after the drug intervention， eight rats were randomly selected from each group， respectively. Gas chromatography-time-of-flight mass spectrometry（GC-TOF-MS） was used to perform targeted metabolomic analysis of SCFAs in the feces of rats， and partial least squares-discriminant analysis（PLS-DA） was applied to compare the differences in metabolic profiles between groups at different treatment times， and to compare the changes in the contents of SCFAs in rat feces between groups. ResultPLS-DA results showed that the blank group could be clearly distinguishable from the model group， with GQT exhibiting a closer proximity to the blank group after 7 d of treatment. After further analyzing the composition of SCFAs， it was found that the proportion of acetic acid increased and the proportions of butyric acid， valeric acid， hexanoic acid and isovaleric acid decreased in the model group compared with the blank group. After the treatment with GQT， the proportions of butyric acid， isobutyric acid， valeric acid， and isovaleric acid increased， and the proportions of acetic acid， propionic acid and caproic acid decreased. Subsequent differential analysis revealed that GQT could significantly improve the content of butyric acid， and had a certain retrogressive effect on the contents of valeric acid and hexanoic acid. ConclusionThe medium dose group of GQT can improve the contents of SCFAs in AAD feces after 7 days of treatment， which may be related to the improvement of the composition ratio of SCFAs and the contents of butyric acid， valeric acid and caproic acid.
