Objective To explore the effect of Chinese herbal medicine formula "tonifying kidney plus strengthening vital energy" on regulating CD40, CD40L protein and mRNA expression in spleen cell in mice with SHENXU. Methods The interaction of CD40L expressed by activated T cells with CD40 on monocytes, macrophages, or B cells is essential for the production of IL-12 and other cytokines. An experimental model of mice with SHENXU by corticosterone was established to observe the effect of Chinese formula on CD40, CD40L protein and mRNA expression in spleen cells or in ConA stimulated spleen cells by immunohistochemistry and RT-PCR. Results No significant differences were found among 5 groups of mice about the CD40 and CD40L protein expression in spleen cells. Both CD40 and CD40L expression detected by immunohistochemistry decreased seriously in ConA induced cells from SHENXU mice (18.9%?3.3% vs 15.8%?2.3%) as compared to that of normal controls(29.7%?4.2% vs 23.3%?1.3%), and so did the mRNA expression on ConA stimulated cells from SHENXU mice. They were restored in different degrees when the SHENXU mice were cured by different Chinese medicine. The effect of "tonifying kidney plus strengthening vital energy" was stronger than that of "tonifying kidney" and "strengthening vital energy" alone. Conclusions "Tonifying kidney plus strengthening vital energy" enhanced the expression of CD40, CD40L mRNA and protein, and this may be one of the mechanisms of improving the status of immune inhibition resulted by Corticosterone.

Aim To study the inhibitory effect of ginkgolide B (BN52021) on the PAF induced changes of chemotaxis of murine peritoneal macrophages and the related polymerization of F-actin.Methods Chemotaxis assays were performed using a modified 48-well Boyden chamber. Actin polymerization of murine peritoneal macrophages was analyzed by flow cytometry using a specific fluorescent stain. Results Peritoneal macrophages significantly migrated toward platelet-activating factor(PAF) through a micropore filter; however, in the presence of PAF receptor antagonist BN52021 (0. 01the actin polymerization of murine peritoneal macrophages induced by PAF in the presence of Ca2+ , but not in Ca2+ -free medium. Conclusion The results suggested that preventing polymerization of F-actin may be a pathway by BN52021 to inhibit the chemotaxis of macrophages, and this effect seems to be Ca2+dependent. The data further indicated that inhibition of PAF induced macrophage chemotaxis is an important mechanism underlying the anti-inflammatory action of BN52021.

BACKGROUND: Applying naloxone in acute brain injury can sustain the cerebral perfusion pressure(CPP), alleviate the cerebral edema and prevent the secondary brain damage to a certain degree. But the dosage and the administration of naloxone in clinical practices vary substantially according to the literatures.OBJECTIVE: To investigate the effect of different doses of naloxone on the changes in the absolute power values of electroencephalography(EEG) in acute brain injury, and study the protective effects of naloxone at different doses.DESIGN: Case-control study based on patients.SETTING: Neurosugery department of a hospital affiliated to a university PARTICIPANTS: From January 2002 to April 2003, at the Intensive Care Unit(ICU) of theNeurosugery Department of the First Hospital Affiliated to the Chongqin Medical University, 86 patients with moderate or severe acute closed brain injury were selected. Of all the patients, 59 were male and 27 were female, aged between 18 - 65.METHODS: According to the degree of injury graded by Glasgow Coma Scale(GCS), the 86 patients bearing acute brain injury were divided into 3 groups: GCS 3 - 5 group, GCS 6 - 8 group and GCS 9 - 12 group. Each group contained a naloxone treatment group and a matched control group. The naloxone treatment group consisted of a low-dose naloxone subgroup and a large-dose naloxone subgroup. The changes in the total power value of EEG before treatment and at the time of 30 minutes, 1, 2, 24, 48, 72 and 120 hours after treatment were measured respectively using quantitative EEG monitor.MAIN OUTCOME MEASURES: The changes in the total power value of the patients' EEG before and after treatment were observed and recorded.RESULTS: The difference between the total power of EEG of the GCS 9 - 12naloxone treatment group 1 hour after a naloxone treatment and that of the matched control group was statistically significant(P ＜ 0.05); The same comparison between the low-dose and the large-dose naloxone subgroups within the GCS 9 - 12 naloxone treatment group yielded no significant difference. In the GCS 6 - 8 naloxone treatment group, the difference between the total power of EEG 1 hour after a naloxone treatment and that of the matched control group was statistically significant, and the large dose subgroup was more significant than the low-dose group. In the GCS 3 - 5 naloxone treatment group, no significant difference between the total power of EEG of the naloxone group and that of the control group could be observed.CONCLUSION: The low-dose naloxone treatment is helpful enough on the intervention for moderate brain injury, and the large-dose naloxone treatment is better than the low-dose on severe brain injury. For the patients with exceptionally severe brain injury, both the two treatments are proved to have no therapeutic effects.

Objective To discuss the psychological behavior intervention methods on reducing the violence behavior of schizophrenia patients. Methods 120 schizophrenia patients were admitted from January to December, 2007 and randomly assigned into the behavior intervention group (group A), the psy-chological support group (group B), the health education group (group C) and the control group (group D) with 30 cases in each group. Group A received routine nursing plus behavior intervention, group B was giv-en routine nursing plus psychological support, group C adopted routine nursing plus health education, group D only received routine nursing. The intervention effect was evaluated with MOAS and the relapse rate of violence behavior went through statistics. Results After intervention, the scores of MOAS decreased sig-nificantly in group A, B, C and D compared with those before intervention. The reduction of MOAS scores in group A, B and C was significantly higher than that of group D, with the highest reduction score in group A and group B and C followed subsequently. The relapse rates of the violence behavior in group A, B and C were significantly lower than those of group D. Conclusions Routine nursing, health education, psycho-logical support and behavior intervention can all reduce and decrease the violence behavior and the inci-dence of the violence behavior, among which behavior intervention proves to be the most effective, and psy-chological support and health education go subsequently.

Objective:To analyze the clinical features and CYP17A1 gene mutation of 17α-hydroxylase/17, 20-lyase deficiency (17OHD). Methods:The clinical data, laboratory examination and genetic results of 6 children with 17OHD in the Department of Endocrinology, Children′s Hospital Affiliated to Capital Institute of Pediatrics from March 2014 to December 2019 were enrolled and analyzed retrospectively.Meanwhile, the clinical types of all congenital adrenocortical hyperplasia (CAH) patients were calculated and then the incidence of 17OHD was calculated.Results:The 6 cases were from 5 families, and the age at diagnosis was ranged from 1 year and 6 months to 15 years old, in which 2 cases were 46, XX and 4 cases were 46, XY.Their gender were all female.Three cases presented with hypertension (50.0%), 4 cases with hypokalemia (66.7%), and 1 case with labia mass (16.7%). The gonad developed into a testis in patients with 46, XY, and patients with 46, XX had ovarian hypoplasia.The laboratory tests revealed an decrease in the cortisol at 8 AM in all cases, ranging from 0.62 to 5.93 mg/L.Five cases displayed an increase in adrenocorticotropic hormone (ACTH) in the range of 84-271 ng/L, and 1 patient with normal ACTH (58 ng/L) had a peak cortisol of 1.75 mg/L after the ACTH challenge test.Elevated progesterone was detected in 6 patients with a normal 17 hydroxyprogesterone level.Further results proved low levels of testosterone and estradiol, and high levels of luteinizing hormone (LH), and follicle stimulating hormone (FSH). CT scan showed mild adrenal hyperplasia in all cases.Among 114 CAH patients during the same period, the incidence of 17OHD came second at 5.3%.The CYP17A1 gene mutation results indicated that 2 unrelated patients were homozygous mutation for p. Y329fs (c.985_987delTACinsAA), 2 siblings were compound heterozygous mutations for p. Y329fs and exon 1-7 deletion, 1 patient was compound heterozygous mutations of p. Y329fs and p. R416C (c.1246C>T), and 1 patient was homozygous mutations for p. L465P (c.1394T> C), which was first reported in China. Conclusions:17OHD is not rare in CAH.Female children with hypokalemia, hypertension, and hypogonadism can lead to diagnostic suspicion of 17OHD.The p. Y329fs mutation in Chinese 17OHD children is a hotspot.The p. L465P (c.1394T>C) mutation is a new mutation in China and it could enrich the mutant spectrum of CYP17A1 gene in China.

Objective To analyze the clinical characteristics and mutation of SLC26A3 gene of a patient with congenital chloride diarrhea in order to deepen the understanding of the disease.Methods The clinical data of the patient who was admitted in Affiliated Hospital of Capital Pediatric Institute in June 2014 were collected.Venous blood of the proband and his parents (2 mL for each) had been extracted for genomic DNA isolation.The 21 exons of SLC26A3 gene were amplified with polymerase chain reaction and screened for mutations by sequencing.Results The main clinical features of the patient included polyhydramnios,preterm,normal birth weight,watery diarrhea,low weight and severe electrolyte disturbances with hypochloremia,hypokalemia,hyponatremia and metabolic alkalosis.Renin angiotensin and aldosterone were high.His urine chloride concentration was low and fecal chloride concentration was high (＞ 90mmol/L).After oral salt substitution therapy with KCl and NaCl [3 mmol/(kg · d),4 mmol/(kg · d)],the electrolyte was better,alkalosis was alleviated,and growth and development were improved.The gene analysis revealed that the patient carried nt1631T ＞ A homozygous mutation on exon 15 which lead to Ile544Asn mutation in the predicted SLC26A3 transmembrane protein sequence,which was considered to be responsible for the functional abnormality of the Cl-/HCO3-protein.His parents were carriers of SLC26A3 gene and their clinical phenotype was normal.Conclusions Congenital chloride diarrhea is a rare autosomal recessive disorder and easily misdiagnosed.The patient of early postnatal diarrhea with persistent hypochloremia,hypokalemia,hyponatremia and metabolic alkalosis should be thought about this disease.Genetic analysis can help make the diagnosis.The prognosis is good if a patient has an early diagnosis and appropriate management.

Objective A 10-years-old girl with Schimke immuno-osseous dysplasia ( SIOD ) was reported and a literature review presented to provide clinical and genetic information of this rare disease. Methods Retrospective analysis of a case of SIOD in Capital Institute of Pediatrics was reported. The patient and her parents' DNA were extracted from blood for detecting SMARCALl gene mutation. Literatures of the disease were reviewed. Results The patient was a ten-years-old girl who admitted because of slow growth in height for 3 years. Herstaturewas123cm(T(p.Q149X)andc.1933C>T(p.R645C)compound heterozygous mutation. A novel nonsense c.445C>T(p. Q149X)was found. One reported missense mutations c. 1933C>T(p. R645C) was detected. We reviewed literatures and found that there were 4 confirmed cases in China including this one. All the 4 cases had the characteristic of short stature, special facial features, osseous dysplasia, pigmentations in body, and proteinuria. However the severity of the disease and genetic changes are not the same. Conclusion When a patient was admitted because of short stature, diagnosis of SIOD should be suspected if he or she also had special facial feature, osseous dysplasia, café-au-lait spots, and proteinuria. Gene test is a tool to help us to make a definite diagnosis of SIOD.

Objective To report clinical characteristics and genetic results of two sisters suffered from congenital adrenal cortex hyperplasia (17-α-hydroxylase deficiency), and relevant literatures were reviewed. Methods Clinical manifestation and laboratory examination data of two sister cases of 17-α-hydroxylase deficiency enrolled in Capital Institute of Pediatrics in March 2016 were analyzed. Sanger sequencing and MLPA for CYP17A1 genes were performed and the parents' genes were also verified. Results The two patients were four years and 10 years old, both suffered from hypokalemia after infections, and hypergonadotrophin gonad hypofunction. One case was with slightly high blood pressure. Laboratory test results showed potassium fluctuation tendency in 1.9~4.0 mmol/L, 17-OHP and DHEA was decreased. Enhanced CT showed different degree of adrenal gland enlargement. Chromosome examination of the older sister is 46, XY. Both sisters demonstrated heterozygous mutation of CYP17A1 gene. The molecular genetic analysis suggested a c.985_987delTACinsAA from father and a deletion spanning exons 1-7 of the CYP17A1 gene from mother. Conclusion 17-α-hydroxylase enzyme deficiency can be diagnosed before adolescence. Clinical hypokalemia with unknown reason and high blood pressure may indicate the disease. The diagnosis can be confirmed with gene sequencing of CYP17A1.
