STUDY DESIGN: A randomized double-blinded controlled trial. SETTING: Assisted Reproduction Unit of Obstetrics and Gynecology Department, Faculty of Medicine, South Valley University, Egypt. DURATION: From December 1st 2017 to the end of October 2018. SUBJECTS and METHDS: Eighty infertile couples that underwent ICSI procedure were entrapped in this study. Patients were divided into two groups;Group I (Vitamin D group) = 40 patients (received vitamin D supplementation in the form of Vidrop oral drops 600 IU/day starting after ovum pickup) and Group II (placebo group) = 40 patients (received a placebo “normal saline oral drop”). RESULTS: There was a significantly increased embryo implantation rates (53.2% in vitamin D group versus 46.7% in placebo group), there was a mild statistically significant difference in the clinical pregnancy rates (45.9% in vitamin D group versus 39.4% in placebo group) with p-value < 0.05 and there was an improvement in ongoing pregnancy rate as there was a mild statistically significant difference in first trimester miscarriage rates (12.5% in vitamin D group versus 17.5% in placebo group) with p value CONCLUSIONS: Vitamin D supplementation could improve embryos implantation rates and rate of ongoing pregnancy by decline in the first trimester miscarriage rate.展开更多

Primary dysmenorrhea, acute or chronic pelvic inflammatory disease, endometriosis, post-operational pelvic adhesion, blood stagnation of pelvic vein, etc. , are mentioned as the often encountered causes of pelvic pain. It has been reported in the recent ten or more years that intramuscular injection of vitamin K3 (Vit K3) could relieve pain induced by smooth muscle spasm. In order to evaluate the effect of Vit K3 administered by acupoint injection in relieving pelvic pain, 180 patients were treated and observed from April 1997 to April 1999 in our hospital, and good therapeutic effect was obtained. It was reported as follows.展开更多

Based on dead-stop endpoint biamperometry by using two platinum foil electrodes with an applied potential difference of 150 mV, vitamin B1 can be oxidized by hexacyanoferrate （ Ⅲ ） in a sodium hydroxide medium via a reversible indicating couple Fe（ CN）6^4- /Fe（CN）6^3- The cell current is linear with the concentration of vitamin B1 in the concentration range of 4. 0 × 10^-6-1.0 × 10^ -3 mol/L with a detection limit of 8.0 ×10 ^-7 mol/L（0. 27 μg/mL）. Most familiar excipients, ions and vitamins do not interfere with the determination of vitamin B1. The method displays the advantages of simplicity, high efficiency（ 180 samples/h）, and high selectivity, and is suitable for the determination of vitamin B1 in pharmaceutical preparations.展开更多

Except for the cases of sympathetic nerve type and spinal cord type, the combined method was superior to traction therapy in the control group and reported as follows.Clinical DataThe Criteria of Diagnosis and Curative Effect in TCM issued by the State Administrative Bureau of TCM and Pharmacy in 1994 was adopted for the enrollment of patients of cervical spondylopathy and the pathological typing. Only the patients who had completed the treatment and with complete records were collected for analysis.展开更多

The author has treated 28 cases of meralgia paresthetica since 1996 by acupuncture plus point-injection with satisfactory results. A report follows.Clinical Data Among the 28 cases, 13 were male and 15 female. Their age ranged from 24 to 72 years, most of the patients being 35 to 50 years; the duration of illness varied from one month to ten years and 6 cases were affected on left side, 8 cases on right side and 14 cases on both sides.展开更多
