A total of 48 terminal cancer patients of Desheng Community were selected for developing life care,psychological support,pain relief and observations.As a result,the main symptoms of terminal cancer patients were alleviated.The average pain scores decreased from 5.6 ± 2.7 to 3.0 ± 2.4,average anxiety scores 14.2 ±6.8 to 6.3 ±3.0 and average depression scores 15.2 ±8.2 to 8.4 ±5.0.There were significant differences according to t-test (P ＜ 0.01).

Objective To investigate the correlation of the expressions of P170,topoisomerase Ⅱ(TOPⅡ)and the proliferation in gliomas.Methods Ki-67 was used as the marker of the proliferation in gliomas.The expressions of P170,TOPⅡ and Ki-67 were tested by S-P immunohistochemical technique using monoclonal antibody to their protein in 54 cases of low-grade gliomas(WHO Ⅰ～Ⅱ grade)and 54 cases of high-grade gliomas(WHO Ⅲ～Ⅳ grade),analysis of the clinical and follow-up were performed.Results The expressions of P170,TOPⅡ and Ki-67 had significant differences between low-grade and high-grade gliomas(P<0.01).Correlation analysis showed that the expression of P170 was negatively related with Ki-67(r=-0.276,P=0.019);the expression of TOPⅡ was positively related with Ki-67(r= 0.637,P<0.001);there was no correlation between the expressions of P170 and TOPⅡ.Conclusion The expressions of P170 and TOPⅡ are associated with the malignant prognosis in gliomas.

Objective:To explore whether the limit of "before the equal-diameter period" is reasonable in the current criteria for "Diagnosis of Kashin-Beck Disease" (WS/T 207-2010) in children, and to provide basic data and technical support for revision of the criteria for "Diagnosis of Kashin-Beck Disease" (WS/T 207-2010).Methods:In 2018, the historical Kashin-Beck disease (KBD) areas in Heilongjiang Province were selected as the investigation sites. The right-hand X-ray films of all children aged 7-12 years old were taken. According to the different X-ray manifestations of the growth and development of the phalangeal epiphysis, they were divided into five periods: before the equal-diameter period, equal-diameter period, ultra-diameter period, pre-closure period and closure period. Firstly, after stratifying by basic data such as age and gender, the data were standardized and analyzed. Secondly, the detection rates of metaphysis-epiphysis (CRME) in each period were calculated and compared. Finally, based on the mean value of the detection rate of metaphyseal change in Linkou and Fuyu counties of Heilongjiang Province in 1990, the rates of expected detection and missed diagnosis of metaphyseal changes of KBD among investigated children were calculated and compared under the limitation of before the equal-diameter period, before the ultra-diameter period or age range reduction.Results:A total of 5 019 children were investigated. The proportion of children before the equal-diameter period was 53.94% (2 707/5 019), and that of before the ultra-diameter period was 77.92% (3 911/5 019). The results showed that the equal-diameter period mainly appeared in 7-10 years old, and showed a decreasing trend with the increase of age (χ 2trend = 390.10, P<0.05); the ultra-diameter period mainly occurred in 10-12 years old, showing a decreasing trend with the increase of age (χ 2trend = 65.39, P < 0.05); the pre-closure period mainly occurred in 10-12 years old, with an increasing trend with the increase of age (χ 2trend = 51.86, P<0.05); the closure period mainly occurred in 11-12 years old and increased with age (χ 2trend = 7.58, P<0.05). The CRME of children in ultra-diameter period was 14.78% (158/1 069), however CRME did not occur in children with equal-diameter period. Among children before equal-diameter period, before ultar-diameter period and aged 7-10 years old, the expected detection rates of metaphyseal changes of KBD were 5.90%, 8.53% and 7.42%, respectively. The expected missed diagnosis rates of metaphyseal changes of KBD were 5.06%, 2.45% and 3.52%, respectively. Conclusion:In order to improve the rate of expected detection and lower the rate of missed diagnosis of metaphyseal changes of KBD, children in "equal-diameter period" should be included in X-ray diagnosis and disease monitoring of KBD.

BACKGROUNDL-glutamate (L-GLU) is a major neurotransmitter in the nucleus ambiguus (NA), which can modulate respiration, arterial pressure, heart rate, etc. This study investigated the effects and mechanisms of L-GLU microinjected into NA on gastric motility in rats.

METHODSA latex balloon connected with a pressure transducer was inserted into the pylorus through the forestomach for continuous recording of the gastric motility. The total amplitude, total duration, and motility index of gastric contraction waves within 5 minutes before microinjection and after microinjection were measured.

RESULTSL-GLU (5 nmol, 10 nmol and 20 nmol in 50 nl normal saline (PS) respectively) microinjected into the right NA significantly inhibited gastric motility, while microinjection of physiological saline at the same position and the same volume did not change the gastric motility. The inhibitory effect was blocked by D-2-amino-5-phophonovalerate (D-AP5, 5 nmol, in 50 nl PS), the specific N-methyl-D-aspartic acid (NMDA) receptor antagonist, but was not influenced by 6-cyaon-7-nitroquinoxaline-2,3-(1H,4H)-dione (CNQX) (5 nmol, in 50 nl PS), the non-NMDA ionotropic receptor antagonist. Bilateral subdiaphragmatic vagotomy abolished the inhibitory effect by microinjection of L-GLU into NA.

CONCLUSIONSMicroinjection of L-GLU into NA inhibits the gastric motility through specific NMDA receptor activity, not non-NMDA receptor activity, and the efferent pathway is the vagal nerves.

AIM:To investigate the effect of phosphatidylinostiol 3-kinase ( PI3K) inhibitor GDC-0032 on cell viability, cell cycle and DNA damage in human glioma U 251 cells.METHODS:The cell viability was analyzed by MTT assay.The cell cycle distribution of U251 cells was examined by flow cytometry .The protein expression was examined by Western blot.The expression and localization of γ-H2AX were determined by laser-scanning confocal microscopy .RE-SULTS:GDC-0032 inhibited the cell viability in a dose-dependent manner .U251 cells showed G 1 phase arrest accompa-nied with upregulation of p 27 protein after exposure to GDC-0032, while the expression of cell division cycle protein 2 (Cdc2) was inhibited.GDC-0032 treatment increased the formation of γ-H2AX foci and histone H2AX phosphorylation in the U251 cells.In addition, GDC-0032 upregulated the phosphorylation levels of mitogen-activated protein kinases , inclu-ding extracellular signal-regulated kinase ( ERK) and c-Jun N-terminal kinase ( JNK) , in the glioma cells , while the ex-pression of survivin was inhibited .CONCLUSION:GDC-0032 inhibits U251 cell growth by inhibition of cell viability and cell cycle progression.GDC-0032 also induces DNA damage of U251 cells.The anticancer activity of GDC-0032 is associ-ated with increasing the activity of ERK and JNK and downregulating the expression of survivin .

The applicator therapy is a unique method to treat infant diarrhea in traditional Chinese medicines and widely applied in clinical practice. Currently, many researchers have proved the rationality of the therapy based on the traditional Chinese medicine mechanism and on the data from clinical practice, but its action mechanism is uncertain at present. In this study, with the assistance of pediatric practitioners, the automated ribosomal intergenic-spacer analysis (ARISA) was adopted to study the effect of the adjuvant therapy with Dingguier umbilical paste on intestinal flora of diarrhea infants, in which Dingguier umbilical paste served as the adjuvant therapy in oral traditional Chinese medicines and fecal samples of infants with different diarrhea symptoms were collected and used as the study materials. The results showed that the adjuvant therapy had a significant effect on the shift of intestinal flora, which was associated with the decrease in the similarity difference to the normal control group and the increase in the number of operational taxonomic units (OTUs) shared with the normal control group. Additionally, adjuvant therapy with Dingguier umbilical paste also showed long action duration and increased OTUs number. These results indicated that Dingguier umbilical paste has the effect in restoring the micro-ecosystem of unbalanced intestinal bacteria. Intestinal flora may be one of major targets for the applicator therapy for the infant diarrhea, but not for the single oral traditional Chinese medicine for infant diarrhea.

This study was aimed to investigate the proliferation activities and phenotype changes of DC, CIK and DC-CIK, and their cytotoxicity against hepatocarcinoma cells in co-culture of DC with CIK. Peripheral blood mononuclear cells (PBMNC) were isolated from healthy adult donors. After incubation of PBMNC for 2 hours, DCs were induced from adherent cells by some cytokines and CIKs were generated from non-adherent cells. Mature DCs were harvested after incubation for 9 days, and then were co-cultured with CIK at ratio of 1:5 for 3 days. The cytotoxicity activity against SMMC-7721 hepatocellular carcinoma cell line was detected by MTT assay. The results showed that CIK cells were able to lyse SMMC-7721 hepatocellular carcinoma cells at low ratios of effector to target. This effect was significantly enhanced by co-culture with DCs. It is concluded that CIK cells have high lytic activity against 7721 hepatocellular carcinoma cell line, which can be enhanced by co-culture with DC. DC-CIK cells are highly effective immune cells.
