Effects of combined vaccination on health related quality of life in children with recurrent respiratory infection / 中国小儿急救医学

Objective To observe the health-related quality of life of children with recurrent respiratory tract infection (RRTI) simultaneously inoculated by pneumococcal vaccine combined with influenza vaccine.Methods A total of 454 cases with RRTI were randomly divided into four groups,the control group (n =135) was used with placebo only,and the combined inoculation group (n =143) was simultaneously inoculated with pneumococcal vaccine combined with influenza vaccine,the pneumococcus vaccine group (n =95),influenza vaccine group (n =81).The PedsQLTM 4.0 score and clinical indicators were observed in each group before the inoculation and 14 months after the inoculation.Results There were no significant differences in the number of cases,gender,age,duration and socioeconomic status score in the four groups (P ＞ 0.05).The incidence of upper and lower respiratory tract infection,respiratory diseases caused by the frequency of fever,the number of days of antibiotic use and total cost of treatment in the vaccine group were significantly less than those of the control group (P ＜ 0.05).And the combined inoculation group was significantly better than the pneumococcus vaccine group and influenza vaccine group(P ＜ 0.0l).The PedsQLTM 4.0 score showed no significant differences among four groups (P ＞ 0.05) before the inoculation.Each dimension of the quality of life of the vaccine group significantly increased (P ＜ 0.05) while those of control group showed no significant difference (P ＞ 0.05).Conclusion Combination of inoculation of pneumococcal vaccine and influenza vaccine can effectively improve the health-related quality of life of RRTI children as well as the PedsQLTM 4.0 score,and it should be highly recommended clinically.

Comparison of caspase-3 activation in tumor cells upon treatment of chemotherapeutic drugs using capillary electrophoresis

Caspases play important roles in cell apoptosis. Measurement of the dynamics of caspase activation in tumor cells not only facilitates understanding of the molecular mechanisms of apoptosis but also contributes to the development, screening, and evaluation of anticancer drugs that target apoptotic pathways. The fluorescence resonance energy transfer (FRET) technique provides a valuable approach for defining the dynamics of apoptosis with high spatio-temporal resolution. However, FRET generally functions in the single-cell level and becomes ineffective when applied in the high throughput detection of caspase activation. In the current study, a FRET sensor was combined with capillary electrophoresis (CE) to achieve a high throughput method for cellular caspase detection. The FRET-based CE system is composed of a homemade CE system and a laser source for detecting the dynamics of caspase-3 in various cells expressing sensors of caspase-3 that have been treated with anticancer drugs, such as cell cycle-independent drug cisplatin and specific cell cycle drugs camptothecin and etoposide, as well as their combination with tumor necrosis factor (TNF). A positive correlation between the caspase-3 activation velocity and drug concentration was observed when the cells were treated with cisplatin, but cells induced by camptothecin and etoposide did not show any apparent correlation with their concentrations. Moreover, different types of cells presented distinct sensitivities under the same drug treatment, and the combination treatment of TNF and anticancer drugs significantly accelerated the caspase-3 activation process. Its high throughput capability and detection sensitivity make the FRET-based CE system a useful tool for investigating the mechanisms of anticancer drugs and anticancer drug screening.

Cheiloplasty by incising along the outline for correction of the defection caused by cheiloschisis operation / 中华医学美学美容杂志

Objective To find a satisfied repairing method which can complete the functional cheiloplasty while avoiding the visible scar after the cheiloschisis II operation for bilateral cleft lip. Methods The functional operation was carried out in subcutaneous layer by incising along the outline of the nose and the mouth. Results A satisfied effect was achieved after 6 months to 2 years' follow up in 15 cases of the patients (4 cases of bilateral cleft, 11 cases of cheiloschisis). Conclusions The new operation method has improved the traditional method of cheiloplasty. It can effectively repair the secondary defection in nose and mouth resulted from the cheilochisis operation. It can rebuild the orbicularis oris muscle and repair the diseased alar catilage as well. Furthermore, it not only brings a natural looking appearance, but also a natural function and an invisible incision scar. [

Mini-incision for frontotemporal lifting by embedding suturing / 中华医学美学美容杂志

Objective To avoid the adverse reactions resulted from scalp scar, alopecia, operation trauma and the length of recovery and other syndromes in the traditional frontotemporal-face lifting. Methods The small incision to dissect the tissue at the frontoparietal and temporal part was used. And the muscle that caused the wrinkle was cut before lifting the dissected tissue and skin while smoothing the wrinkles on the face. Results Of 68 cases in the clinic, 11 cases were with temporal lifting by embedding suturing; 25 with temporal lifting with mini incision by embedding suturing; 32 with frontotemporal lifting with mini incision by embedding suturing. The follow up showed that the result of such operation method was satisfactory. No scalp scar, alopecia and other syndromes occurred. Conclusions This method of frontotemporal lifting with mini incision by embedding suturing has such advantages as: operating process is simple and can be done in the operating room of the Out patient Department, the trauma is not so serious that it takes little time to recover, the cut is so small that the scar is invisible, frontotemporal face lifting is very positive and satisfactory.
