DynaPulse, a newly developed noninvasive apparatus, is valuable in assessing blood pressure, cardiac output and vascular compliance. The purpose of the present study was to evaluate the validity of cardiac output measurement using DynaPulse in patients, compared with echocardiography and Fick method. Forty five inpatients underwent cardiac output measurement using DynaPulse (CO DP ) and Doppler echocardiography (CO DE ), cardiac output was measured with DynaPulse (CO DP ) and Fick method (CO FM ) in additional 26 patients. A good correlation was found between CO DP and CO DE ( r =0 76). There was an acceptable correlation between CO DP and CO FM ( r =0 61). DynaPulse can provide a noninvasive, clinically useful estimation of cardiac output.

Conclusion There are different kinds of apoptosis cell in vitrectomy specimens of proliferative vitreoretinopathy.It is suggested that apoptosis might be one of the important mechanisms of regulating the degree in proliferative vitreoretinopathy.

Objective To observe the effects of Sanhuangtangshenkang particles on the expression levels of tumor ne?crosis factor (TNF)-α, interleukin (IL)-6 in bone tissue of type 2 diabetic (T2DM) rat model. Methods There were seven groups of rats in this study. Ten female Wistar rats were used as control. Ten rats were established for osteoporosis model, and fifty rats were established for diabetic model. Fifty diabetic model rats were further divided into model control group, tra?ditional Chinese medicine (TCM) prevention group (high-dose TCM group, low-dose TCM group) and Western medicine group, with 10 rats for each group. All rats were given the corresponding intervention for 20 weeks. Automatic biochemistry analyzer was used to determine fasting blood glucose (FBG). ELISA was used to detect serum TNF-αand IL-6. Dual-energy X-ray absorptiometry (DXA) was used to assess bone density. Real-time PCR was used to appraise the mRNA of TNF-αand IL-6 in bone tissue. Western blot assay was used to measure protein expressions of TNF-αand IL-6 in bone tissue. Re?sults Compared with osteoporosis model group, bone density was significantly increased, serum levels of TNF-αand IL-6, the mRNA and protein expression level of IL-6 were significantly decreased in bone tissue of TCM groups and Western medi?cine group (P<0.05). The expression levels of TNF-αmRNA and protein were significantly decreased in bone tissue of in high-dose TCM prevention group and Western medicine group (P<0.05). Compared with the diabetic model group, the se?rum levels of FBG, TNF-αand IL-6 were significantly decreased in TCM groups and Western medicine group (P<0.05). The expression levels of TNF-αmRNA and protein were significantly decreased in high-dose TCM prevention group and Western medicine group (P<0.05). The mRNA and protein expression levels of IL-6 were significantly decreased in low-dose TCM prevention group and Western medicine group (P<0.05). Conclusion The expression levels of TNF-αand IL-6 are increased in serum and bone tissue of diabetic rats. Sanhuangtangshenkang particles can improve the inflammatorystate to play prevention and therapeutic effect on diabetic rats.

OBJECTIVE: To study the effect of Chinese herbal medicine 1023 Recipe in blocking cancer transformation of experimental oral precancerous lesion and its mechanism. METHODS: We treated the experimental oral precancerous lesion in hamster's cheek pouch using 1023 Recipe (consisting of Radix Astragali, Gynostemma Pentaphyllum, Rhizoma Chuanxiong and selenium-rich green tea) for 6 weeks, and observed its effect in blocking cancer transformation, detected 2 kinds of agglutinin receptors (receptors of wheat germ agglutinin and Ricinus communis agglutinin) in the mucosa of the hamster's cheek pouch. RESULTS: The rate of cancer transformation in 1023 Recipe treated group was lower than that in the control group without treatment (P<0.05). Agglutinin receptors in the two groups were different significantly. CONCLUSION: 1023 Recipe is effective in treating hyperplasia, and can prevent its cancer transformation. The mechanism may be that 1023 Recipe can induce precancerous lesions to differentiate into normal tissues.

OBJECTIVE:To explore the ideas for the prescription comment of TCM injections,and provide reference for clini-cal rational use. METHODS:Totally 9 457 prescriptions in PIVAS and 400 hospitalized medical records in our hospital in 2015 were collected. The prescriptions and hospitalized medical records which contained TCM injections were retrospectively commented in aspects of indications,usage and dosage,drug combination,solvent selection and repeat medication,and analysis of typical case. RESULTS:In 2015,there were 2 544 prescriptions(26.90%)in PIVAS and 195 medical records(48.75%)that used TCM injections;the irrational use was mainly inappropriate solvent selection(50.70%),inappropriate usage and dosage(27.00%),inap-propriate indications (10.33%),inappropriate combination therapy (7.51%) and repeat medication (4.46%). CONCLUSIONS:Prescription of TCM injections should be commented with the medical records and individual analyzed;in terms of unreasonable prescriptions and medical records TCM clinical pharmacists should actively intervene unreasonable prescriptions by the bed.

Objective To evaluate the imaging features and causes of cerebral cortical laminar necrosis(CLN) in children,to improve understanding this sign.Methods The imaging and clinical data of 33 children diagnosed with CLN were analyzed retrospectively.The imaging features of CT and MRI were summarized and compared according to their etiologies.Results Children cerebral CLN involved multiple lobes of bilateral hemicerebrum, including the cortical region, subcortical region and basal ganglia region, and linear or gyral shape,patchy shape and punctate shape abnormal density or signal were demonstrated.The typical imaging features were high-signal intensity over the lateral cortical surfaces or along the gyri on T1WI and FLAIR.Diffusion weighted imaging(DWI) showed high signal with restricted diffusion on acute-stage, and Gd-DTPA enhancement demonstrated linear or gyrate enhanced appearance on early-stage.The extent of CLN of cerebral infarction was relatively limited.Acute anoxic encephalopathy showed an early imaging change and extensive involvement.While chronic anoxic encephalopathy and inflammatory encephalopathy showed a late imaging change and a longer existence.Conclusion Children cerebral CLN may have various causes and imaging features,and show characteristic chronological signal changes on imaging studies.The different causes result in the different patterns for CLN in distribution and time distribution.

Objective To investigate MRI findings and its relationship with clinical grading and prognosis of infant muggy syn-drome (IMS).Methods Twenty five cases of IMS diagnosed newly and nine cases of IMS with follow-up were collected.MRI find-ings were retrospectively analyzed and compared with their clinical data.Results Seven early abnormal signs could be shown on cer-ebral MRI examination.There was no correlation between the clinical grading and three abnormal signs,which were subdural effu-sion,supratentorial cerebral edema and subarachnoid hemorrhage (P >0.05).In contrast,the other four abnormal signs (abnormal signal of subcortex and cortex,diffuse cerebral hemorrhage,basal ganglia and corpus callosum edema or infarction,large area cere-bral infarction)were closely related to the severity of clinical symptom (P <0.05).MRI findings had certain correlation with clinical classification.Conclusion MRI can objectively reflect the serious change of brain damage in IMS,and provide important information for clinical therapy and prognosis.

Objective To explore the mechanism of Xiaoying decoction on experimental autoimmune thyroiditis (EAT) rats in view of regulatory T cells and Th17 cells.Methods SD rats were divided into five groups,normal control group,model control group,tripterygium glycoside group,Xiaoying decoction low and high dose groups.Except for normal control group,the other groups were established the model of EAT.Rats in the Xiaoying decoction low,and high dose groups were given Xiaoying decoction of 17.24 and 68.95 g·kg-1;rats in the tripterygium glycoside group were given tripterygium glycoside 6.25 mg·kg-1.The serum free triiodothyronine(FT3),free thyrocyte(FT4) and thyroglobulin antibody were detected by RIA method.Thyrocyte morphology was observed under optical microscope.The expression levels of Foxp3 mRNA and IL-17 mRNA were detected by real-time PCR.The changes of Treg cells and Th17 cells were analyzed by flow cytometry.Results Compared with the normal control group,FT3,FT4 and TgAb were increased in the model control group (P ＜0.01,P ＜0.01,P ＜0.05).Compared with the model control group,FT3,FT4 and TgAb were decreased in tripterygium glycoside group and Xiaoying decoction high dose group (P ＜ 0.05).The infiltration score in the normal control group,model control group,tripterygium glycoside group,Xiaoying decoction low and high dose groups were 0,4,4,3.5,2.Compared with model control group,the infiltration was improved (P ＜0.01).Foxp3 mRNA expression was decreased while IL-17 mRNA increased in the model control group as compared with the normal control group(P ＜ 0.01).In contrast,the expression of Foxp3 mRNA was increased and IL-17 mRNA expression was decreased in Xiaoying decoction low and high dose groups,tripterygium glycoside group as compared with the model control group (P ＜0.05).Compared with the normal control group,rats in the model control group had fewer Treg cells and more Th17 cells (P ＜0.01).Compared with the model control group,the percentage of Treg cells was elevated and Th17 cells was reduced in tripterygium glycoside group and Xiaoying decoction high dose groups (P ＜ 0.01).Conclusion The therapeutic mechanism of Xiaoying decoction on EAT rats may be related to changing the percentage of regulatory T cells and Th17 cells with up-regulating the expression of Foxp3 mRNA and down-regulating the expression of IL17mRNA.
