ObjectiveTo explore the relationship between the changes of the blood platelet counts (BPC) in children with cerebral palsy (CP) and pather mechanism of CP in traditional Chinese medicine.MethodsBPCs of CP children and healthy children were analyzed with statistical method.ResultsThe BPC of CP children was higher than that of the healthy children ( P<0.05).ConclusionThe BPC of CP children is higher than that of the healthy children, and this is consistent with the theory of traditional Chinese medicine about pathogenic mechanism of CP that CP is related to blood stasis.

Objective To study the characteristics of IgA nephropathy (IgAN) secondary to ankylosing spondylitis (AS) compared with primary IgAN.Methods Clinical and pathologic data were collected in patients who were diagnosed with IgAN by renal biopsy and admitted to our hospital from Jan 2007 to Sep 2015.Patients with IgAN secondary to AS were recruited by the ratio 1 ∶ 5 of patients with primary IgAN as control group at the same period.Results There were 15 patients in AS group,proportionately 75 patients in the control group.Compared with those in control group,patients in AS group had shorter disease course [(10.1 ± 8.3) months vs (20.2 ± 27.9) months] and lower proportions of renal insufficiency and hypertension[1/15 vs 52.0％ (39/75);1/15 vs 46.7％ (35/75)].In laboratory tests,quantitative 24 hour urinary protein and serum ereatinine were significantly lower in group AS than those in the control group [(1.42±0.67)g vs (2.88 ±1.35)g;(79.0±18.2)mmol/L vs (145.3 ±77.6) mmol/L].The Lee grading of IgAN in two groups was comparable.The treatment in both groups was similar including steroids,immunosuppression agents,angiotensin-converting enzyme inhibitors and angiotensin receptor blockers.After follow-up from 1 to 6 years,3/11 patients in AS group and 22.8％ (13/57) (13/75) in control group developed deterioration of renal function.Conclusion Patients with IgAN secondary to AS have shorter disease course and milder condition compared with patients with primary IgAN.Clinical outcome of renal function in both groups is similar according to comparable treatment.

OBJECTIVE To investigate the role of cinnabar and realgar in Angong Niuhuang Wan (AGNH) -produced neuroprotection against lipopolysaccharide ( LPS) -mediated neuronal damage and further explore the corresponding mechanisms. METHODS Primary rat midbrain neuron-glia cultures were used as an in vitro model to investigate effects of AGNH on LPS-mediated degeneration of dopamine (DA) neurons. The experiment was divided into normal control group, LPS model group, LPS + cinnabar (4 and 40 mg·L-1) groups, LPS + realgar (4 and 40 mg·L-1 ) groups and LPS + AGNH (40 and 400 mg·L-1 ) group. Drugs were added 30 min before LPS treatment. After 7 d, dopaminergic neurotoxicity was assessed through the quantification of tyrosine hydroxylase (TH)-positive neurons and morphological analysis of TH-positive neurons; the activation of microglia was evaluated using OX-42 antibody; the gene expression of tumor necrosis factor-α (TNF-α) and induced nitric oxide synthase (iNOS) mRNA in microglia was performed by real-time RT-PCR analysis, and the release of TNF-α and nitric oxide (NO) in the supernatant of neuron-glia cultures was determined respectively by the ELISA and Griess reagent. RESULTS Compared with normal control group, DA neurons in LPS model group decreased by 40% (P <0.05) , microglial activation was induced, the expression of TNF-α mRNA and iNOS mRNA in microglia increased 9 and 2 times, respectively ( P < 0. 05 ) , and subsequent production of TNF-α and NO in the supernatant of neuron-glia cultures increased 20 and 30 times, respectively (P<0.05). Compared with LPS model group, AGNH 400 mg·L-1 and realgar 40 mg·L-1 significantly attenuated LPS-mediated DA neuronal loss by 40% and 30% , respectively (P<0.05) and inhibited activation of microglia and expression of TNF-α mRNA by 61% and 52% (P <0.05). iNOS mRNA was reduced by 58% and 51% (P <0.05 ) in microglia. The subsequent release of TNF-α was reduced by 55% and 43% (P<0.05) and NO reduced by 53% and 34% (P<0.05) in the supernatant of neuron-glia cultures. Cinnabar had no inhibitory effect on LPS-induced changes. CONCLUSION AGNH protects LPS-induced neurotoxicity through its anti-inflammatory properties and realgar might be the key contributor to the neuroprotective action of AGNH, while cinnabar fails to show any neuroprotection.

Objective To design the disease transfer table of standardized communication between the maternity ward and the operating room,and explore the application effect of disease transfer table based on situation (S)-background (B)-assessment (A)-recommendation (R) communication in cesarean delivery of maternal. Methods 570 pregnant women and 30 medical staff from two wards of maternity ward were selected as research object, the first ward was the control group, the second ward was observation group. The control group used traditional way of disease transfer,and the observation group used SBAR transition table for disease transfer, compared the incidence of adverse events after caesarean section of puerperal and the satisfaction of disease transfer of medical staff from two groups. Results The incidence of wound bleeding, postpartum hemorrage caused by uterine inertia, wound infection of observation group was 2.06%(6/291), 1.71%(3/291), 1.37%(4/291), which was lower than 3.94%(15/279), 3.58%(10/279), 4.66%(13/279) of control group (χ2=4.41, 4.17, 5.31,P < 0.05). The satisfaction of comprehensive, state of the iuness, work acceptance, transfer efficiency of medical staff was (4.75 ± 0.12), (4.82 ± 0.55), (4.86 ± 0.67), (4.76 ± 0.22) points, which were higher than (3.04 ± 0.29), (3.11 ± 0.35), (3.09 ± 0.32), (3.01 ± 0.42) points of control group (t=2.72-3.12,P < 0.05). Conclusions The SBAR condition transition table can improve the efficiency and quality of disease transfer between maternity ward and operating room, ensure the care safety of cesarean section maternal.

Objective To observe the influence of Baicalin and Octreotide on lung injury of rat with severe acute pancreatitis(SAP) and discuss the therapeutic effect and mechanism of the two medicines on SAP.Methods The improved Aho(?)method was adopted to pre- pare SAP rat models via retrograde injection of 3.5% sodium taurocholate to the pancreatic duct.The 135 SAP rat models after being pre- pared were randomly divided into the model group,Baicalin treatment group and Octreotide treatment group with 45 rats in each group;an- other 45 were selected to be the sham operation group which only received abdomen opening surgery.The above - mentioned groups were then randomly divided into 3h,6h and 12h groups with 15 rats in each group.Observed respectively at 3h,6h and 12h after operation,the mortalities of all rat groups followed by batch execution of rats,and then observed the gross pathological and pathological changes of lung. The tissue microarrays technology was applied to prepare the lung tissue microarrays sections.The changes in Bax and bcl-2 protein ex- pression levels of lung tissue of each group were observed via immunohistochemical staining and meanwhile the TUNEL method was applied to observe the lung cell category and apoptotic index changes of lung tissue in each group.Results The 12h survival of model group was 66,67% while those of Baicalin treatment group and Octreotide treatment groups were both 100%,indicating a marked difference(P＜0.05).Comparison of lung pathological score disclosed:The model group and Baicalin treatment group obviously exceeded the sham oper- ation group at various time points(P＜0.01);at 6h and 12h the Baicalin treatment group was obviously less than the model group(P＜0.05)and the Oetreotide treatment group less than the model group(P＜0.01).Comparison of Bax protein of lung in each group dis- closed:The Baicalin treatment group and Octreotide treatment group obviously exceeded the sham operation group and model group at 3h (P＜0.05),meanwhile the Baicalin treatment group obviously exceeded the Octreotide treatment group(P＜0.01).Changes of lung bcl -2 protein expression level of all groups disclosed:The model group and Baicalin treatment group obviously exceeding the sham operation group(P＜0.01)as well as the Octreotide treatment group(P＜0.05)at different time points,the Baicalin treatment group was obviously less than the model group at 6h(P＜0.05).The peak of apoptosis occurred to the Baicalin treatment group at 6h,but statistics showed no obvious difference among all groups at different time points(P＞0.05).Conclusions(1)Both Baicalin and Octreotide have protecting effect on SAP lung injury and their therapeutic mechanism is possibly related to apoptosis.The application of tissue microarrays in SAP pathological examination can save manpower and material resources,cut down the experimental cost and improve the experimental efficien- cy,thus worth popularizing.
