Observation on Shenqi Fuzheng injection combined with cefoxitin sodium after cesarean section.

This paper aims to observe the effect of Shenqi Fuzheng Injection combined with cefoxitin sodium after cesarean section. Clinical data of 126 puerperae were retrospectively analyzed. They randomized into control group and treatment group, and there were 63 cases in each group. Patients in control group were given Cefoxitin Sodium treatment. And patients in treatment group were given Shenqi Fuzheng Injection on the basis of control group. After 7 days of treatment, the clinical curative effect of the two groups was observed and compared. The body temperature of the patients in treatment group was significantly decreased when compared with control group on the 2nd and 3rd day after operation (P<0.05); the first exhaust time and defecation time of patients in treatment group were significantly shortened when compared with control group (P<0.05); the postoperative hemoglobin and red blood cell count in both groups were all significantly increased when compared with before treatment (P<0.05), and the treatment group were evidently higher than control group (P<0.05); the postoperative neutrophilic granulocyte percentage, white blood cell count and lymphocytes percentage in both groups were all significantly lowered when compared with before treatment (P<0.05), and the neutrophilic granulocyte percentage, white blood cell count and lymphocytes percentage in treatment group were significantly lowered when compared with control group (P<0.05). Shenqi Fuzheng injection combined with cefoxitin sodium after cesarean section can effectively reduce the postoperative maternal body temperature and promote the recovery of maternal gastrointestinal function, which is conducive to the repair of uterus, further correct anemia after cesarean section and prevent postpartum infection. Its clinical curative effect is ideal, with certain clinical application value.

Refractive index modulating Raman spectroscopy based on perovskite PMN-PT ceramics.

A three-layer planar waveguide structure comprising a perovskite (1-x)Pb(Mg1/3Nb2/3Nb2/3)O3-xPbTiO3 (PMN-PT) ceramic sandwiched by two silver films is designed and called PMPW. Using the high sensitivity of ultrahigh-order modes, theoretical analysis is performed to calculate the effective refractive index (ERI) of the PMPW. A detailed analysis of the Raman spectrum of PMN-PT at 795 cm-1 is performed. A comparison of the numerical analysis and experimental results reveals that the nonlinear change in ERI plays a primary role in the Raman signal variation. Analysis of the Raman spectrum of a sample deposited on PMPW confirms that it is effective for modulating Raman signals.
