AIM: To study the effect and the mechanism of crenulatin, an effective constituent of Chinese traditional medicine, on apoptosis of cerebral microvascular endothelial cells. METHODS: The following terminal concentrations of crenulatin were used in the study: 25 mg/L and 100 mg/L. Apoptosis of mouse cerebral microvascular endothelial cells (bEnd. 3 cell line) was evaluated by flow cytometer, immunocytochemical assay (Fas, Bcl - 2) and Western blotting (caspase - 3) after culture for 24 h. RESULTS: Compared with control group, apoptosis of bEnd. 3 cells in 25 mg/L group was significantly inhibited ( P ＜0.05), but apoptosis in the 100 mg/L group was significantly increased (P ＜ 0.05). In apoptosis inhibited group, the Fas immunocytochemical staining was weaker, the positive cells were significantly decreased ( P ＜ 0.05) and caspase - 3 expression was decreased compared with control group; however, the Bcl - 2 staining was stronger and the positive cells were significantly increased ( P ＜ 0.05). On the other hand, in apoptosis increased group ( 100 mg/L group), the changes were just opposite. CONCLUSIONS: The effect of crenulatin on apoptosis of mouse cerebral microvascular endothelial cells possesses a dual - direction change, inhibitive effect in 25 mg/L and stimulative effect in 100 mg/L group, respectively. The mechanism is related to the alterations of Fas/Bcl - 2 expression and caspase - 3 activity.

Objective To observe the effect of pre-intervention with electroacupuncture at Neiguan (PC 6) plusα2-adrenoceptor (α2AR) agonist on peri-operative heart rate variability (HRV).Method A total of 120 patients going to receive lower limb orthopedic surgery were randomized into four groups by using the random number table, namely a control group (group A), an electroacupuncture group (group C), anα2AR agonist group (group D) and an electroacupuncture plus medication group (group N), 30 cases in each group. The indicators of heart rate variability (HRV), including the standard deviation of normal-to-normal (N-N) intervals (SDNN), standard deviation of the average of N-N intervals (SDANN), root mean square successive differences (rMSSD), percentage of adjacent N-N intervals>50 ms apart (pNN50), low-frequency power (LF), high-frequency power (HF), LF/HF and total power (TP) were recorded 1 d prior and 1 d after the operation; meanwhile, the mean arterial pressure (MAP) and heart rate (HR) were recorded before incubation (T0), right after incubation (T1), 5 min after incubation (T2), right afterextubation (T3), 5 min after extubation (T4), 60 min after extubation (T5), and 180 after extubation (T6).Result In group N, the HR and MAP at the other time points were insignificantly different from those at T0 (P>0.05); in group A, the HR and MAP at T1-T6 were significantly different from those at T0 (P<0.05); in group C and D, the HR and MAP at T1-T4 were significantly different from those at T0 (P<0.05); the HR and MAP in group N were significantly lower than those in group A at T1-T6 (P<0.05) and were significantly lower than those in group C and D at T1-T4 (P<0.05); the HR and MAP in group C and D were significantly lower than those in group A at T5 and T6 (P<0.05). In group A, the LF, HF, LF/HF and TP 1 d after the operation were significantly increased compared to those 1 d prior to the operation (P<0.05); in group A and D, the SDNN, SDANN, rMSSD, and pNN501 d after the operation were significantly lower than those 1 d prior to the operation (P<0.05); the LF, HF, LF/HF, and TP in group C, D and N were significantly lower than those in group A 1 d after the operation (P<0.05); the SDNN, SDANN, rMSSD, and pNN50 in group C and N were significantly higher than those in group A and D 1 d after the operation (P<0.05). Conclusion Pre-intervention electroacupuncture plusα2AR agonist can improve the balance of cardiac sympathetic and vagus nerves, and better maintain the peri-operative hemodynamic stability.

Objective To investigate the effect of full nutrition management on cancer patients with chemotherapy, and to support theory bases for the standardized clinical nutrition of cancer patients. Methods From January 2016 to December 2017, a total of 88 patients with the first chemotherapy were recruited and randomly divided into experimental group and control group, with 44 patients in each group. These patients all complied with the inclusion and exclusion criteria, and volunteered for the study. The two groups all received the same of anti-tumor treatment and the same conventional nutritional support (according to the results of nutrition screening and nutrition assessment, the nutritional support was formulated and patients′dietary guidance was given), while only patients of the experimental group were given full nutritional management, including regularly following up the patient′s condition changes, gastrointestinal reactions, and the feed. According to the five-step treatment model of malnutrition, nutritional support was improved in a timely manner, and appropriate nutritional support was provided. At the end of chemotherapy, the change of weight, albumin, prealbumin, hemoglobin was compared with that before treatment in the two groups. Results After chemotherapy, albumin, prealbumin, hemoglobin had no obvious drop compared with that before treatment in two groups (P>0.05). The patients of experimental group showed stable weight after chemotherapy: (53.39 ± 9.24) kg vs. (54.66 ± 9.41) kg, P>0.05. Weight loss in the control group after chemotherapy was statistically significant:(54.61 ± 10.76) kg vs. (56.52 ± 10.46) kg, P<0.05. Conclusions The full nutritional management can help maintain nutrition status during chemotherapy, especially can prevent the weight loss.

Objective: To retrospectively analyze the serum calcium level in sepsis patients, understand the influencing factors of abnormality calcium metabolism, and analyze the effect of serum calcium level on sepsis prognosis. Methods: From January 1, 2017 to January 31, 2018, clinical data about sepsis patients admitted hospital were collected. The patients were divided into 2 groups according the levels of serum calcium measured in patients admitted in 24 h: normal serum calcium group (serum calcium 2.03-2.67 mmol/L), and low serum calcium group (serum calcium<2.03 mmol/L). And this study did not find hypercalcemia patients. The data about laboratory test index were compared between two groups. Results: Fifty-two cases were included in this study, including 14 cases of normal serum calcium and 38 cases of hypocalcemia, and the incidence rate of hypocalcemia was 73.1%(38/52). The level of serum calcium in hypocalcemia group was (1.78 ± 0.17) mmol/L, and was (2.16 ± 0.14) mmol/L in normal serum calcium group. The main position of infections in patients with sepsis were digestive system, respiratory system and urinary system. Compared with that in the normal serum calcium group, the number of malnutrition patients in the hypocalcemia group was more. The total protein (TP), albumin (ALB), prealbumin (PAB) and total cholesterol (TCH) in the nutritional status of the patients were lower, the sequential organ failure assessment (SOFA) scores was higher, the prothrombin activity (PTA) was lower, the prothrombin time (PT) was prolonged, and international normalized ratio (INR) was increased. The differences were statistically significant (P<0.05 or <0.01). Pearson correlation test was used to screen the tests and scores related to the concentration of serum calcium. The results showed that the serum calcium concentration was negatively correlated with the level of SOFA scores, procalcitonin (PCT), PTA, thrombin time (PT), activated partial thromboplastin time (APTT) and INR (r=- 0.431, - 0.361, - 0.441, - 0.431, - 0.427, - 0.420, P<0.01 or<0.05), and the serum calcium concentration was positively correlated with TCH, TP, ALB and PAB (r=0.442, 0.475, 0.463, 0.419, P<0.01). Conclusions Hypocalcemia is related to the nutritional status of the body, and is related to coagulation function, serum protein level, PCT concentration and SOFA scores. The decrease of serum calcium indicates that multiple organ dysfunction syndrome may occur, and should be paid more attention to.

Giant tumor cells and their varieties in the bone marrow were found in 7 patients with abnomal hematopoiesis phenomena. These cells were artificially devided into 5 kinds according to the difference of their morphology. Most of these cells were corresponding to lymphoid-monocytoid-macrophagocytoid cells with Wright's staining, cytochemical stainings, immunocytochemical stainings, flow cytometry examination, electron microscopy and pathologic study. The bone marrows were hypercellular and marked dysplastic hematopoiesis phenomena. Two of the 7 cases were diagnosed as malignant lymphoma with bone marrow biopsy. All cases characteristically showed no lymph node enlargement or hepatosplenomegaly or any local tumor mass. As to the prognosis of these cases, two patients died with survival time of 8 and 17 months, respectively, one was on critical condition at course of 10 months, and the other 4 cases were in comparatively stable condition with courses of 2.5 to 24 months. These patients seem to be a group of rare malignant lymphoid-monocytoid-macrophagocytoid proliferative diseases.

Objective: To explore the intervention effect of multiple nutritional health guidelines for school-aged children on the knowledge, attitudes and practices (KAP) of primary school students in Chengdu. Methods: A primary school in Chengdu, which had a school canteen, was selected as the intervention school, and another similar primary school was selected as the control school. Students from the intervention school received nutritional education for six months, while the control school did not provide such intervention measures. A total of 589 students from grades 3 to 5 were selected to participate in the questionnaire survey(eligible 558, missing 31). Results: Before the intervention, no significant difference was found in the rate of awareness regarding nutritional knowledge, including dietary attitudes and dietary behavior. After the intervention, the rate of awareness of nutritional knowledge and the overall awareness rate reached more than 80% in the intervention group, which was significantly higher than that observed in the control group(P<0.05). The intervention group consumed less than one type of breakfast food(26.6%), which was less than the control group(49.4%). The frequency of weekly egg and milk consumption was higher in the experimental group than in the control group. The proportion of students who consumed three or more types of vegetables daily was higher in the intervention group than in the control group. The proportion of leftovers was lower in the intervention group (15.8%) than in the control group(57.9%). Conclusion The comprehensive nutritional education based on a variety of nutritional health guidelines for school-age children can enhance students awareness of nutritional knowledge and healthier dietary behaviors.

Objective To determine the spectrum of mutations responsible for Phenylalanine hydroxylase (PAH) deficiency on phenylketonuria (PKU) patients of Han Chinese people in the Huaihai region of central China.Methods One hundred and one patients diagnosed with PKU were referred to Xuzhou Maternity and Child Health Care Hospital for genetic counseling/analysis from January 2003 to December 2013.Thirteen exons of PAH gene mutations,as well as their flanking introns,were identified in 202 of chromosomes using polymerase chain reaction-single strand conformation polymorphism(PCR-SSCP) and sequencing.Results (1) The spectrum was composed of 24 different mutation types,which had been submitted to the National Center for Biotechnology Information(NCBI) dbSNP databases under accession number SS#2137543837_SS#C2137543860.(2)The most commonly affected region was exon 7 and its flanking introns.The most prevalent mutations were c.728G ＞ A (p.R243Q),followed by c.721C ＞ T (p.R241C),c.1155G ＞ C(p.L385L),c.1068C ＞ A(p.Y356X),c.-71A ＞ C(-71A ＞ C) and c.60 + 62C ＞ T (IVS1 +62C ＞T),accounting for 18.317％,8.416％,4.950％,3.960％,3.465％ and 2.970％ of the mutant chromosomes,respectively.(3)Two novel mutations were identified in PAH gene in PKU patients of Han Chinese people:c.60+62C＞T(IVS1 +62C ＞T) and c.782G ＞T(p.R261L).Conclusions The vast majority of PAH mutations identified corresponded to those observed for the PKU populations in the other regions in China,whereas a few are considerably different from others.The mutational spectrum of PAH gene found in patients with PKU in the Huaihai region exhibit regional association.

Objective To explore serum level of 25-hydroxy vitamin D3 (25 [OH]D3) and its correlations with sleep quality and cognitive function in patients with chronic insomnia disorder (CID).Methods Fifty CID patients,admitted to our hospital from October 1,2016 to September 1,2018,and 40 healthy controls were enrolled.Pittsburgh Sleep Quality Index (PSQI) was used to assess insomnia severity (objective sleep status being assessed using polysomnography throughout a night in some patients).Montreal Cognitive Assessment scale (MoCA) was used to evaluate the general cognitive function.Serum level of25(OH)D3 was detected by ELISA.Results As compared with the controls,CID patients had significantly higher PSQI scores (P＜0.05) and statistically higher Hamilton's Depression Scale-17 scores (P＜0.05).The CID patients had significantly lower MoCA scores,having more errors in object work,spatial work and object recognition memorizes in Nine-Box Maze Test than the controls.Partial correlation analysis showed that in CID patients,the level of 25(OH)D3 was negatively correlated with PSQI scores (r=-0.320,P=0.030),spatial working memory errors (r=-0.300,P=0.043) and disease course (r=-0.360,P=0.014),whereas it was positively correlated with total sleep time (r=0.515,P=0.014)and MoCA scores (r=0.422,P=0.003).Conclusion The level of 25 (OH)D3 decreases in the CID patients,which is correlated with insomnia severity and course,and may affect the cognitive function.
