OBJECTIVETo investigate the effect of Si' an Capsule combined Enalapril on hypertensive trough/peak ratio (T/P) and circadian rhythm of blood pressure in patients with essential hypertension (EH).

METHODSSixty patients with EH of stage II, III were randomly divided into two groups, the 30 patients in the treated group were treated with Si' an capsule combined Enalapril, and the 30 patients in the control group were treated with Enalapril alone. All patients were given 24-hour ambulatory blood pressure monitoring before and after 4 weeks treatment. T/P of systolic and diastolic blood pressure (SBP & DBP) of each group were calculated. Circadian rhythm of blood pressure was observed at the same time.

RESULTST/P of SBP and DBP in the treated group was 62.4 +/- 7.0% and 66.3 +/- 8.1% respectively, which was obviously higher than that in the control group, 53.3 +/- 6.7% and 60.1 +/- 7.2%, respectively (P < 0.05). The blood pressure circadian rhythm recovering rate in the treated group was 73.3% and in the control group 50%, the difference was insignificant.

CONCLUSIONThe combination therapy of Si' an capsule and Enalapril could lower the blood pressure smoothly and restore the circadian rhythm of blood pressure in EH patients.

OBJECTIVETo analyze the condition of early (≤ 30 d) postoperative pulmonary infection in children after living donor liver transplantation (LDLT).

METHODThe clinical data of 36 cases undergoing LDLT in Children's Hospital of Chongqing Medical University were analyzed retrospectively from June 2006 to December 2009.

RESULTOf 36 cases without preoperative respiratory disease, 17 were boys, 19 were girls. Their age ranged from 2 months to 14 years. Pulmonary infection developed in 24 patients, of whom 4 cases died (17%) and 3 deaths were related to pulmonary infection. Pulmonary infection occurred in 17 of 20 infants (85%) and 10 of 11 cases (91%) with liver function of Child-Pugh grade C. Twenty cases (83%) developed pulmonary infection within first 2 weeks after LDLT. Totally 65 pathogenic strains of microorganisms were isolated, in which Gram-negative bacteria, Gram-positive bacteria and fungi were 46 strains, 5 strains, 14 strains respectively. The most frequently isolated bacteria were Pseudomonas aeruginosa (14 strains), Klebsiella pneumoniae (8 strains) and Acinetobacter baumannii (8 strains). Pseudomonas aeruginosa showed a resistance rate of almost 100% to cotrimoxazole, tetracycline, chloramphenicol, ampicillin, the first, the second and some of the third generation cephalosporins. Klebsiella pneumoniae producing extended spectrum beta-lactamase had a resistance rate of almost 100% to beta-lactams except carbapenems. Acinetobacter baumannii was exquisitely susceptible to carbapenems, but showed a high resistance to penicillins and cephalosporins. Candida albicans, which was the most common fungus, showed a susceptibility rate of 100% to amphotericin B. In the LDLT recipients of pulmonary infection, cytomegalovirus (CMV) infections occurred in 2 patients and Epstein Barr virus (EBV) infection in 1 patient.

CONCLUSIONThe incidence of early postoperative pulmonary infection was high in children undergoing LDLT, especially in infants. And the mortality should not be ignored. The high risk period for infection was within the first 2 weeks after operation. The pathogens were mainly Gram-negative bacteria, which showed high and multidrug resistance.

Colorectal cancer (CRC) is a common malignancy burdening people globally, with increasing morbidity and mortality nowadays, due to the alternation in the diet type and lifestyle in modern society. Berberine, a type of benzylisoquinoline alkaloid, is widely present in numerous medicinal plants, particularly including Coptidis Rhizoma. Mounting evidence reveals that berberine possesses an array of pharmacological effects, such as anti-inflammation, anti-bacterium, anti-cancer, anti-diabetes mellitus and so on. In particular, berberine exhibits substantial inhibition on various types of cancers including CRC. Hereby, we sought to systematically review the suppressive effect of berberine on CRC through the diminishment of the proliferation and metastasis, induction of apoptosis, arrest of cell cycle, regulation of inflammatory reaction, the reverse of chemotherapeutic resistance and restoration of gut microbiota in CRC, so as to shed light on the in-depth mechanisms underlying the treatment of CRC with berberine in the clinical setting.

Objective To explore the effect of Internet addiction on adolescent's attention.Methods Neuropsychological evaluations of attention function were done separately in 18 adolescents who met the diagnostic criterion for Internet addiction and in other 18 ones without Intemet addition tendency as a control group. With auditory and visual oddball paradigms, and stimulated by standard,target and novel stimuli, EEG was recorded and analyzed to get the event-related potential P300 and compare the latency and amplitude of P3a and P3b between the 2 groups. Results Compared with the controls, the attention of Internet addiction group was decreased significantly in neuropsychological evaluations. The latency of P3a potentials induced by novel stimulus was much shorter and the amplitude of it was higher in addiction group than in control group, but the latency of P3b potentials generated by target stimulus was prolonged and the amplitude decreased obviously. Conclusions Intemet addiction can cause damage to adolescent's attention function. There is a correlation between the attention impairment and the change of P300 potentials.

HSV-1, a neurotropic virus, always leads to severe nervous symptoms. It is hard to completely eradicate the latent viruses after conventional therapy so that recurrence is inevitable. ICP is a key regulator for HSV replication and transcription that determines the cytolytic infection or latent state. In search of new anti-virus strategy targeting HSV-1ICP4, two pairs of siRNA were designed, and a recombinant eukaryotic lentiviral expression plasmid pLKO-puro(r)-hU6-siRNA was constructed. Vero cells were transfected with the designed siRNAs by Lipofectamine 2000 and four stable monoclonal cell lines were established by puromycin screening method. The ICP4 expression at mRNA level was detected with real-time PCR, and the HSV-1 replication was measured with TCID50 assay. SiRNA was shown as an effective way to inhibit the expression of ICP4 in monoclonal cell lines. Meanwhile, HSV-1 replication was significantly inhibited when ICP4 was shut down by siRNA. We conclude that siRNA targeting ICP4 attenuates HSV-1 replication. Further more, multi-site siRNAs show stronger inhibitory effect on viral replication, which may be an effective and feasible approach for biological anti-viral drugs.

Anti-H antibody belongs to IgM type cold antibody, which often induces the unconformity of positive and reverse typing and leads to the difficulty in clinical blood typing. Anti-H antibody was found during identification of the counter blood group in 3 cases. The antibody was found to be active at 37 degrees C, room temperature and 4 degrees C when determined by blood group serology, and was finally analyzed to be IgM. It is suggested that not to give erythrocytes of O group unreasoningly to blood recipient of AB group during emergent moment, but instead, to give same type of blood. If there was no same type of blood during urgent events, O type erythrocytes could be employed after being matched by saline centrifuging with host side coincidence and screened by incomplete method. In this case, anti-H antibody leading to adverse-reaction in blood transfusion should be prevented.

Background/Aims: Endoscopic ultrasound-guided fine needle biopsy (EUS-FNB) is an essential tool for tissue acquisition in solid pancreatic tumors. Rapid on-site evaluation (ROSE) by cytologists ensures diagnostic accuracy. However, the universal application of the ROSE is limited by its availability. Therefore, we aimed to investigate the feasibility of determining the end of the procedure based on the results of in-room cytological evaluation by trained endosonographers (IRCETE). Methods: A training course focusing on the cytological interpretation of common pancreatic tumors was provided to the three endosonographers. After training, the decision to terminate EUS-FNB was made based on IRCETE results. The diagnostic accuracy, concordance rate of diagnostic categories, and sample adequacy were compared with those determined by board-certified cytologists and macroscopic on-site evaluation (MOSE). Results: We enrolled 65 patients with solid pancreatic tumors, most of whom were malignant (86.2%). The diagnostic accuracy was 90.8% when the end of the procedure was determined based on IRCETE, compared to 87.7% and 98.5% when determined by MOSE and cytologists, respectively (p=0.060). Based on the cytologists’ results, the accuracy of IRCETE in diagnostic category interpretation was 97.3%. Conclusions In the absence of ROSE, IRCETE can serve as a supplementary alternative to MOSE in determining the end of tissue sampling with a high accuracy rate.

Triple-negative breast cancer (TNBC) remains difficult to treat and urgently needs new therapeutic options. Nintedanib, a multikinase inhibitor, has exhibited efficacy in early clinical trials for HER2-negative breast cancer. In this study, we examined a new molecular mechanism of nintedanib in TNBC. The results demonstrated that nintedanib enhanced TNBC cell apoptosis, which was accompanied by a reduction of p-STAT3 and its downstream proteins. STAT3 overexpression suppressed nintedanib-mediated apoptosis and further increased the activity of purified SHP-1 protein. Moreover, treatment with either a specific inhibitor of SHP-1 or SHP-1-targeted siRNA reduced the apoptotic effects of nintedanib, which validates the role of SHP-1 in nintedanib-mediated apoptosis. Furthermore, nintedanib-induced apoptosis was attenuated in TNBC cells expressing SHP-1 mutants with constantly open conformations, suggesting that the autoinhibitory mechanism of SHP-1 attenuated the effects of nintedanib. Importantly, nintedanib significantly inhibited tumor growth via the SHP-1/p-STAT3 pathway. Clinically, SHP-1 levels were downregulated, whereas p-STAT3 was upregulated in tumor tissues, and SHP-1 transcripts were associated with improved disease-free survival in TNBC patients. Our findings revealed that nintedanib induces TNBC apoptosis by acting as a SHP-1 agonist, suggesting that targeting STAT3 by enhancing SHP-1 expression could be a viable therapeutic strategy against TNBC.
