Seasonal influenza is a common respiratory infectious disease with high morbidity and strong infectivity, and it is harmful to people. Influenza vaccination is an effective measure to prevent influenza and reduce the spread of the influenza. People who are in great risk of influenza or tend to have adverse reactions should be considered as a special population, including the young child less than 2 years, the men or women older than 65 years, children with egg allergy and pregnant women. The attitudes about the safety and efficacy of influenza vaccine in special populations should be changed following the improvement of the influenza vaccine production and the deeply research. This paper reviewed the production of common flu vaccines and the safety of influenza vaccination in special populations.

Fructose-1,6-bisphosphatase(FBPase) deficiency is a rare inherited metabolic disease,which is an autosomal recessive metabolic disorder.Affected patients usually present with metabolic crisis including severe hypoglycemia and metabolic acidosis.Each attack occurred with a similar sequence.The triggering factors are removed and then clinical status is improved dramatically.As patients are usually symptomless in the plateau stage,it is often misdiagnosed.Metabolite assay in blood and urine is very useful for the diagnosis of FBPase deficiency.FBPase is a key enzyme in gluconeogenesis.Deficiency of FBPase impairs the formation of glucose from all precursors.FBP1 gene mutation contributes to the disease.More than 30 mutation types have been reported.There is no specific treatment.Early diagnosis and appropriate life-style can prevent repetitive metabolic derangements,improving life quality of these children and ensuring successful pregnancy.

Cytokines can have either pro-or anti-inflammatory activity and immunosuppressive activity,depending on the microenvironment.Tumors contain immune cells and a network of pro-and anti-inflammatory cytokines,which collaborate in the development and progression of cancer.Cytokine might prove to be prognostic.The systemic effects of pro-inflammatory cytokines are associated with fatigue,depression,cognitive impairment,anorexia,cachexia,pain,toxicity of treatment and resistance to treatment,which can affect quality of life.

Objectives: To explore the destructive mechanism of P.gingivalis on periodontium and to better understand the pathogenic effects of P.gingivalis fimbriae. Methods:Western blotting was used to detect the degradation effects of P.gingivalis ATCC 33277 and its fimA-deficient mutant on focal adhesion components paxillin and focal adhesion kinase (FAK) of Hela cells and immortalized gingival epithelial cells (IHGE cells). Results:P.gingivalis ATCC 33277 wild strain and its fimA-deficient mutant induced degradation of paxillin and FAK both in Hela cells and in IHGE cells. fimA-deficient mutant had a remarkable weaker degradation ability than the wild strain. In IHGE cells, paxillin and FAK were degraded in a time-and MOI-dependent manner. Conclusion:P.gingivalis fimbriae-mediated adhesion and invasion to epithelial cells may promote the degradation of focal adhesion components. IHGE cells may be more suitable for the study of periodontal pathogens than Hela cells.

Objective To investigate the dynamic change and different apoptosis of T lymphocyte subsets in patients with acute pancreatitis.Methods Forty-four patients with MAP and 32 with SAP were enrolled in this study.Blood samples were collected on the lst,3rd and 7th d after onset.T lymphocyte subsets and their apoptotic rate were determined by flow cytometry.Results Compared with the control group and MAP group,CD4+ T lymphocytes and the ratio of CD4+/CD8+remarkably decreased while the apoptotic rate of CD4+ T cells significantly increased in patients with SAP.However,there was no marked difference in apoptotic rate of CD8+ T cells among different groups.Conclusion The different apoptosis of T lymphocyte subsets in AP,especially in SAP,results in severe and sustained cellular immune suppression.

OBJECTIVETo observe the differences in the clinical efficacy on menopausal irritability between acupuncture and medication.

METHODSSixty cases of menopausal irritability were randomized into an acupuncture group (31 cases) and a medication group (29 cases). In the acupuncture group, the warming needling manipulation was applied at the key acupoints such as Hegu (LI 4) and Taichong (LR 3), once a day, 10 treatments made one session. Totally, 2 sessions were required. In the medication group, 2.5 mg diazepam tablets were prescribed, three times a day, for 23 days totally. The clinical efficacy, the modified Kupperman score and self-rated health measurement scale (SRHMS) were compared before and after treatment in the two groups. RESULTS The total effective rate was 87. 1% (27/31) in the acupuncture group and 82.8% (24/29) in the medication group. The difference in the clinical efficacy was not significant between the two groups (P > 0.05). The modified Kupperman score and SRHMS score were both reduced obviously after treatment in the two groups, indicating the significant difference (all P < 0.05). The reduction of two scores in the acupuncture group was more obvious than those in the medication group (Kupperman: 15.23 +/- 6.19 vs 18.45 +/- 5.37; SRHMS: 116.29 +/- 38.24 vs 140.34 +/- 42.15, both P < 0.05).

CONCLUSIONThe acupuncture and medication are effective in the treatment of menopausal irritability, but the efficacy of warming needling manipulation is better than that of diazepam tablets.

Objective:To study the effects of green-tea polyphenol, (epigallocatechin gallate,EGCg) on the cellular inflammatory responses of gingival epithelial cells. In order to find out a safe and efficient inflammation-inhibitor for periodontitis prevention and treatment. Methods:A model of cellular inflammatory responses of gingival epithelial cells stimulated by Porphyromonas gingivalis vesicles in vitro was established. The effects of EGCg on PGE2 production of gingival epithelial cells was detected by ELISA. Further more, the effects of EGCg on COX (cyclooxygenase)-2 and MMP (matrix metalloproteinase)-3 mRNA expression were determined by Real-time RT-PCR. Results:EGCg dose-dependently inhibited PGE2 production and COX-2, MMP-3 mRNA expressions. Conclusion:EGCg has inhibitory effects on cellular inflammatory responses of gingival epithelial cells and possesses the potentiality to be a periodontal inflammation-inhibitor.

The application of human embryonic stem cell(hES cell) contributes a lot to the disease treatment,and shows a great potentiality especially in organ transplantation and tissue engineering.Although hES cell therapy has not reached clinical application,some newly achieved results are encouraging.This review mainly presents results recently published in applying hES cell for disease treatment.

Objective To study the protection of crocetin on myocardial ischemia-reperfusion injury and the possible mechanism involved. Methods Infarction model: Coronary occlusion was maintained for 45 min and reperfused for 180 min to produce infarction model. Creatine kinase (CK) and lactate dehydrogenase (LDH) activity in serum of infarction groups were analyzed at baseline (before ischemia), 5, 60, and 180 min after reperfusion. Stunned model: Stunned model was achieved by ligating the left anterior descending branch of coranary artery for 15 min. Na+, K+-ATPase, and Ca2+, Mg2+-ATPase activity, total adenosine content (TAC), and energy charge (EC) in ischemic and nonischaemic myocardial tissue and malondialdehyde (MDA) in serum of stunned groups were analyzed at the end of 180 min of reperfusion. Haemodynamic parameters including heart rate, left ventricular end-systolic and end-diastolic pressure, ejection fraction, maximum and minimum dp/dt, maximum and minimum dV/dt, and stroke work, were monitored at baseline, 5, 30, 90, and 180 min after reperfusion. Results Crocetin could attenuate the infarction ratio, relieve stunning in a dose-dependent manner, and decrease the CK and LDH activities in serum. Crocetin (50 mg/kg) could improve the heart function, ameliorate myocardial stunning degree, and increase the level of ATP and EC in myocardial tissue. Conclusion Crocetin could protect myocardium from ischemia and following reperfusion, then prevent the myocardial infarction and relieve myocardial stunning. The underlying mechanism may be partly attributed to the improvement of energy restoration and free radical scavenging effect.
