Objective To analyze the influencing of vascular endothelial growth factor (VEGF) gene polymorphism on success rate of embryo implantation in patients with thin endometrium. Methods A total of 100 patients with thin endometrium from the gynecological outpatient and inpatient departments of the hospital from June 2022 to December 2023 were selected as study group, and another 100 healthy adult women from the physical examination department in the same period were selected as control group. Polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP) was used to determine the single nucleotide polymorphism at four different loci of the VEGF gene. Allele-specific PCR (AS-PCR) was used to analyze the distribution of VEGF genotypes and allele frequencies at the corresponding loci in both groups. The study group underwent frozen-thawed embryo transfer (FET), and their pregnancy conditions were confirmed by ultrasound 30 to 35 days later. Based on pregnancy outcomes, the study group was divided into successful pregnancy group and failed pregnancy group, and VEGF gene polymorphism between the two groups was compared. Logistic regression analysis was conducted to investigate the influence of VEGF gene polymorphism on pregnancy outcomes in patients with thin endometrium. Receiver operating characteristic (ROC) curve was plotted to assess the predictive value of VEGF gene polymorphism for pregnancy failure in patients with thin endometrium. Results Compared with the AA+CA genotype at the -2578C/A locus, patients carrying the CC genotype had increased risk of developing thin endometrium by 1.412 times (95%CI, 1.004 to 1.985), and the allelic mutation C showed increased risk by 1.526 times (95%CI, 1.066 to 2.186). Similarly, compared with the GA+AA genotype at the -1154G/A locus, patients carrying the GG genotype had increased risk of developing thin endometrium by 1.467 times (95%CI, 1.011 to 2.128), and the allelic mutation G showed increased risk by 1.531 times (95%CI, 1.026 to 2.284). There were no significant differences in VEGF gene genotypes and allele distributions at the -460C/T and +936C/T loci between the two groups (P>0.05). Among the 100 patients with thin endometrium in the study group, 40 cases had successful pregnancies after FET. There were significant differences in the distribution of VEGF gene genotypes at the -2578C/A and -1154G/A loci between the successful pregnancy group and the failed pregnancy group (P < 0.05). Logistic regression analysis revealed that carrying the CC genotype at the -2578C/A locus and the GG genotype at the -1154G/A locus were risk factors for pregnancy outcomes in patients with thin endometrium (OR>1, P < 0.05). The ROC curve showed that the area under the curve (AUC) for predicting pregnancy failure in patients with thin endometrium based on VEGF gene polymorphisms at the -2578C/A and -1154G/A loci was 0.801(95%CI, 0.552 to 0.838). Conclusion Carrying the CC genotype at the -2578C/A locus and the GG genotype at the -1154G/A locus can increase the risk of developing thin endometrium and reduce the success rate of pregnancy in patients with thin endometrium. Moreover, VEGF gene polymorphisms at the -2578C/A and -1154G/A loci can effectively predict the risk of pregnancy failure in patients with thin endometrium.

Objective To explore key points of nursing in treatment of tibial bone defect by united Ilizarov technology and bone transport. Methods A total of 12 patients treated tibial bone defect with combined Ilizarov technology and bone transport were retrospectively analyzed and summarized. Results All 12 patients were followed up for 5 to 24 months. Their average bone healing time was (9. 4 ± 2. 6) months, and average external fixation removal time was (10. 6 ± 2. 6) months. In one case, a little infection happened to the nail trail; after removal of crusts, the local part was cleaned with 75% alcohol cotton swab and kept dry, then the infection became better 2 days later. In another case, nonunion happened between the bone transport segment and the distal segment, so bone graft was done again. 2 cases of limb pain became better after delaying bone transport. No patients had complications due to nursing care. Conclusions Application of Ilizarov technique combined with bone transport on the treatment of tibial bone defect has advantages like small trauma, quick bone healing, equal length of lower limbs, and flexible knee joints. To guarantee operation effect and to improve patients′satisfaction, what is needed is postoperative observation and nursing of complications, psychological nursing, nursing in bone transport period, functional exercise and discharge guidance.

BACKGROUND: Infrared spectrum technology has potential and important value of application in diagnosing disease and analyzing pathology, as well as providing references for proper treatment. OBJECTIVE: To analyze the distinctive pathological information in the spectrums of infrared radiation at Neiguan (PC 6) acupoint of patients with coronary atherosclerotic heart disease (CAHD). DESIGN: Case-control study.SETFING: Longhua Hospital Affiliated to Shanghai University of Traditional Chinese Medicine. PARTICIPANTS: The study was conducted from April 2003 to April 2005 in patients with CAHD from Out-Patient Clinic in Longhua Hospital (21 males and 29 females, averagely 58.1 years). Forty-seven healthy volunteers were all from advertisement (25 males and 22 females, averagely 50.6 years). All the subjects were voluntary. METHODS: PHE201, a high-sensitive infrared spectrum detective device (Shanghai Institute of Technical Physics of Chinese Academy of Sciences, China) was applied to detect the spectrums of infrared radiation at Neiguan in 50 patients with CAHD and 47 healthy adults were selected as control for comparison. The scanning range was from 1.5μ m to 16μ m,73 detected wavelength spots were scanned at Neiguan of all the subjects, and the scanning spacing was 0.2μ m. MAIN OUTCOME MEASURES: Intensity of infrared radiation at Neiguan between CAHD patients and normal controls at different wavelengths. RESULTS: The intensities of infrared radiation of CAHD patients were significantly different from that of the healthy volunteers at 32 spots of the right Neiguan as well as at 23 spots of the left Neiguan among the 73 detected wavelength spots(P < 0.05-0.001). At 2-2.5μ m wavelength spots that were related to the energy metabolism, the intensities of infrared radiation of CAHD patients were significantly lower than the healthy volunteers (P < 0.05-0.005). Concerning the difference in intensities of infrared radiation between the left and the right Neiguan, the CAHD patients had more wavelength spots than healthy volunteers did (P < 0.001). CONCLUSION: ①Distinctive pathological information exists in the infrared spectrums at Neiguan in CAHD patients. ②CAHD patients have hypo-activities of energy metabolism and hypo-function ofqi and blood in the area of Neiguan.

OBJECTIVE: To observe the changes of volt-ampere characteristics of Yuan-Primary acupoints in women before, during and after menstruation, and to find out the relationships between Qi-blood in human body and volt-ampere characteristics of acupoints, so as to develop a new method for quantitative analysis on changes of Qi-blood. METHODS: A high-sensitive detection system of volt-ampere characteristics of acupoint was applied to detecting the volt-ampere characteristics of Taiyuan (LU 9), Daling (PC 7) and Shenmen (HT 7) in healthy women before, during and after menstruation. RESULTS: The resistances on LU 9, PC 7 and HT 7 with some certain scan currents were quite different among the women before, during and after menstruation. For such changes, PC 7 was of the most obvious change, LU 9 was of the less and HT 7 was of the least. The total ratio of the scanning spots with significantly increasing changes of resistances on these three acupoints along with the menstrual process was 70.6%. CONCLUSION: The volt-ampere characteristics of acupoints vary with the menstrual process, which is of the acupoint specificity. The resistances on the acupoints increase with the menstrual process, and such results may be due to the blood loss during menstruation. The volt-ampere characteristics can be used as a quantitative index to study on the change of Qi and blood.
