Objective To explore self-emulsifying particle size characterization methods and compare the regularity of various methods. Methods By setting the clarity level of turbidity standard solution, with two less soluble drugs-diterpene lactone compounds Chuanhuning and dihydropyridine drug nifedipine as model drugs, 10-12 clarity level prescriptions were selected from six different ternary phase diagram. Laser particle size scanner was used to determine the particle size, and UV-visible spectrophotometry to determine its absorbance. Three methods of particle size characterization rules were compared by drawing charts. Results There was a positive correlationship among droplet particle size, absorbance and clarity grade of emulsion formed by prescription in the same phase diagram. But, there was no regularity among droplet particle size, absorbance and clarity grade of emulsion formed by prescription in different phase diagram. Conclusion The droplet particle size of emulsion formed by prescription containing the same drugs and excipients in different proportions can be compared by clarity with visual method or absorbance with UV-visible spectrophotometer.

Objective To investigate the risk factors of reoperation in patients with Crohn's disease recurrence.Methods The clinical data of 108 patients with Crohn's disease who were admitted to the Peking Union Medical College Hospital from March 2004 to September 2013 were retrospectively analyzed.Of the 108 patients,82 received single operation and 26 received reoperation.Twenty-five factors which might influence the reoperation were analyzed,which were gender,age,blood type,preoperative levels of white blood cells,neutrophils,lymphocytes hemoglobin,albumin,prealbumin,high sensitive-C reactive protein (hs-CRP),anti-saccharomyces cerevisiae antibody (ASCA),anti-neutrophil cytoplasmic antibody (ANCA),location and type of the lesions,extraintestinal manifestation,perianal lesions,history of smoking,appendectomy,course of the disease before the first operation,pre-operative administration of immunosuppressants,body mass index (BMI) before the first operation,onodera prognostic nutrition index (OPNI),enteral nutrition,emergent operation,complications after the first operation.The univariate analysis was done using the chi-square test or Fisher exact probability,and the multivariate analysis was done using the Logistic regression model.Results The results of univariate analysis showed that the level of preoperative prealbumin,hs-CRP,location and type of the lesion,the history of smoking,preoperative administration of immunosuppressants,enteral nutrition before the first operation were the risk factors of reoperation in patients with Crohn's disease (x2=5.928,4.805,7.491,12.363,5.229,9.026,16.506,P ＜ 0.05).The results of multivariate analysis showed that the lesion located at the ileocolon,administration of immunosuppressants prior to the first operation for 1 year and energy provided by enteral nutrition under 500 kcal/d before the first operation were the independent risk factors of reoperation (OR =1.908,3.535,5.489,95％ confidence interval:1.035-3.518,1.087-11.494,1.816-16.590,P＜0.05).Conclusions Patients with lesions located at the ileocolon,administration of immunosuppresants prior to the first operation for 1 year and energy provided by enteral nutrition under 500 kcal before the first operation have higher risk of Crohn's disease recurrence and reoperation.

AIM: To investigate the activity of interleukin-1? converting enzyme in transplanted intracerebral rat gliomas under angiotensin II-induced hypertension chemotherapy. METHODS: The brain tumor model was produced in Wistar rats by stereotaxic inoculation of C6 glioma cells (1?10 12 /L). Tumor-bearing rats were treated with carmustine, teniposide and lisplatin (chemotherapy) during angiotensin II-induced hypertension. Then, the survival time of tumor-bearing rats, tumor blood flow, the concentration of drug, volume of gliomas and the activity of interleukin-1? converting enzyme in glioma were examined.RESULTS: The survival time of tumor-bearing rats was significantly longer in chemotherapy with angiotensin II-induced hypertension group than that of chemotherapy alone. In addition, regional tumor blood flow, the concentration of chemotherapeutic drug and the activity of interleukin-1? converting enzyme in transplanted rat gliomas were increased, while the volume of gliomas was decreased in hypertention chemotherapy group compared with chemotherapy alone. CONCLUSION: Chemotherapy with angiotensin II-induced hypertension has a enhancing effect on chemotherapy for improving the drug delivery to tumor tissue by a increased tumor blood flow and enhancing activity of interleukin-1? converting enzyme.

AIM:To study the protection and mechanism of Asclepiadaceae against the damage of neuron by free radical. METHODS:The model of ischemia and damaged neuron induced by H 2O 2 was made respectively. The protection of Asclepiadaceae was observed with the measurement of contents of MDA in brain and cultured neuron, transudatory rate of LDH, breaking rate of DNA and clearance rate of?OH in cultured neuron. RESULTS:Asclepiadaceae decreased the raising of MDA in brain induced by ischemia. The raising of transudatory rate of LDH,breaking rate of DNA and content of MDA inducing by H 2O 2 in cultured neuron were also observed. The clearance rate of?OH in cultured neuron increased as the contents of Asclepiadaceae raised. CONCLUSION: The mechanism of Asclepiadaceae protecting the neuron is related to its ability to clean up free radical.

Objective To study the value of BCSG1 on evaluating the curative effect of neoadjuvant chemotherapy(NC) for breast cancer.Methods The expression of BCSG1 in cancer tissue was assayed by immunohistochemistry and RT-PCR in 36 cases of breast cancer patients before and after receiving NC of CEF(cyclophosphamide,epirubicin and fluorouracil) regimen.The therapeutic response of NC was evaluated by morphological and pathological observation.The relationship between expression of BCSG1 and morphological response to NC was analyzed.Results Among the studied cases,the diameter of tumor significantly decreased(P

Objective To explore the antidepressant effects of low dose fisetin combined with piperine and its possible mechanism. Methods The tail suspension test and the forced swimming test were used to explore the antidepressant ef-fects of low dose fisetin combined with piperine. In addition, the locomotor activity test was used to exclude the false positive effect in behavioral despair tests. High performance liquid chromatography (HPLC) was used to determine the expression of monoamine. The monoamine oxidase activity in the mouse brain was also determined by fluorospec-trophotometry. Results The results showed that fisetin (1.25 mg/kg, 2.5 mg/kg and 5 mg/kg, ig) combined with piperine (2.5 mg/kg, ip) significantly reduced the duration of immobility in both tail suspension and forced swimming tests. The effective doses did not alter locomotor activity. Moreover, neurochemical assays showed that its produced an increase in monoamine levels in the hippocampus, fronal cortex and amygdala. Monoamine oxidase (MAO) activity in the mouse brain was inhibited while MAO-B activity was not affected. Conclusion These findings suggestde that low dose fisetin combined with piperine exerted antidepressant effect in behavioral despair tests and the underlying mechanism may in-volve the inhibition monoamine oxidase activity in the mouse brain.

Objective:To investigate the effect of sevoflurane and propofol on cognitive function, respiratory and circulatory function, and stress response in patients undergoing laparoscopic radical gastrectomy.Methods:A prospective randomized controlled study was conducted. A total of 116 patients who underwent laparoscopic radical gastric cancer surgery in Liangshan Yi Autonomous Prefecture Hospital of Integrated Chinese and Western Medicine from January 2021 to January 2022 were selected, and all patients were divided into the propofol group and the sevoflurane group according to the random number table method, with 58 cases in each group. Propofol anesthesia was used in the propofol group and sevoflurane anesthesia was used in the sevoflurane group. The anesthesia-related indexes and respiratory and circulatory function indexes, oxidative stress parameters and cognitive function indexes neuron-specific enolase (NSE) levels, Mini-Mental State Examination (MMSE) scale score, and complications at different time points were compared between the 2 groups.Results:There were no statistically significant differences in the baseline data between the 2 groups (all P > 0.05). The differences in intraoperative bleeding, pneumoperitoneum time and anesthesia onset time between the 2 groups were not statistically significant (all P > 0.05); eye opening time [(13.2±2.6) min vs. (17.6±3.7) min] and respiratory recovery time [(12.6±2.2) min vs. (16.5±2.3) min] of patients in the sevoflurane group were shorter than those in the propofol group, and the differences were statistically significant ( t values were 7.41 and 9.31, respectively, both P < 0.001). Repeated measurement analysis of variance showed that the temporal, intergroup and temporal-intergroup interaction differences in heart rate, mean arterial pressure and oxygen saturation before induction of anesthesia, immediately after induction of anesthesia, and at the time of anesthesia duration of 10 min, anesthesia duration of 20 min, and anesthesia duration of 30 min between the propofol group and the sevoflurane group were not statistically significant (all P>0.05). The temporal, intergroup and temporal-intergroup interaction differences in the oxidative stress indexes of blood glucose, adrenaline, adrenocorticotropin, and cortisol between the 2 groups were statistically significant (all P < 0.001). The levels of blood glucose, epinephrine, adrenocorticotropin and cortisol in the sevoflurane group were lower than those in the propofol group immediately after induction of anesthesia, and at the time of anesthesia duration of 10 min, anesthesia duration of 20 min, and anesthesia duration of 30 min. The level of NSE before anesthesia in the propofol group and the sevoflurane group was (6.6±0.8) ng/ml and (6.5±0.7) ng/ml, respectively, and there was no statistically significant difference ( P > 0.05). The level of NSE in the sevoflurane group was higher than that in the propofol group immediately after surgery [(8.9±0.8) ng/ml vs. (8.2±0.9) ng/ml], 6 h after surgery [(10.2±1.2) ng/ml vs. (9.5±1.0) ng/ml], and 24 h after surgery [(9.3±1.1) ng/ml vs. (8.2±0.9) ng/ml] and 48 h after surgery [(8.7±0.9) ng/ml vs. (8.1±0.9) ng/ml]; and there were temporal, intergroup and temporal-intergroup interaction differences in NSE level of the 2 groups (all P < 0.001). The MMSE score in the sevoflurane group was lower than that in the propofol group immediately after surgery, 6 h after surgery, 24 h after surgery, 48 h after surgery, the temporal, intergroup and temporal-intergroup interaction differences in MMSE scale score of the 2 groups were statistically significant (all P < 0.001). The incidence of postoperative complications in the propofol group and the sevoflurane group was 24.1% (14/58) and 25.9% (15/58), respectively, and the difference was statistically significant ( χ2 = 2.12, P = 0.833). Conclusions:Sevoflurane and propofol anesthesia have no significant effect on the respiratory and circulatory functions of patients undergoing laparoscopic radical surgery for gastric cancer, whereas propofol has a smaller effect on cognitive functions, and sevoflurane inhibits oxidative stress better. Both of them are worthy of clinical application.
