Objective To study the relationship between Lidocaine blood drug level and the cause of death from Lidocaine anaphylactic shock. Method Comparing and analyzing the blood drug levels by HPLC between two groups of people whose various indexes are normal before the surgery. Group 1 included 8 cases who accepted Lidocaine as anesthetic and died from Lidocaine anaphylactic shock. Group 2 included 11 cases who also took Lidocaine as anesthetic and passed the surgery smoothly. Results Lidocaine blood level of Group 1 (1.61?0. 45mg/L) is lower than that of Group 2 (2. 44 ?0. 47mg/L). Conclusion Lidocaine blood drug level has nothing to do with the cause of Lidocaine anaphylactic shock.

Purpose:To study the expression level of bcl 2 gene in breast cancer tissues, paracancer tissues, metastatic lymph nodes and normal tissues. To study the relation of the gene expression and tumor formulation, development and clinical significance. Methods:Semi fixed quantity RT PCR was performed in 16 patients to detect the level of bcl 2 gene expression in cancer tissues, paracancer tissues, metastatic lymph nodes and normal tissues. Results:The relative values of mRNA in cancer tissues was 0.264?0.137 and 0.272?0.076 in metastatic lymph nodes and 0.131?0.083 in paracancer tissues were higher than those in normal tissue (0.033?0.031), so the difference was significant( P

In this paper, the specific male sequeuce in paraffin section of various tissues with autolys is ofdifferent degrees was detected by polymerase chain reaction(PCR).The results shewed that PCR could be used for identifying sex in the tissues with low degrees ofautolysis; its positive rate was lower in high degrees with disappearance of nuclaic member and cell ou-tline,and often gave false negative results when the autolysis degree was high.

Objective:To investigate the pathogenic gene locus and prenatal genetic diagnosis of 54 families with oculocutaneous albinism (OCA).Methods:This retrospective study enrolled 54 OCA probands and their families from Gansu Province Maternal and Child Health Care Hospital from May 2014 to May 2020. TYR gene variation screening was performed on the probands by Sanger sequencing. Those with negative results were analyzed by high-throughput sequencing, and further verification was performed on their parents by Sanger sequencing. Among the 54 families, 15 ml amniotic fluid were collected from 16 women at 18-21 gestational weeks in their subsequent pregnancy. Sanger sequencing combined with short tandem repeats sequence for linkage analysis were performed for genetic analysis. All data were analyzed using descriptive statistical analysis. Results:Out of the 54 OCA probands, 48 were diagnosed as OCA1, five were OCA2 and one was OCA4 based on the Sanger sequencing and high-throughput sequencing detection. A total of 26 different variation sites were involved in the 48 OCA1 probands, including 15 missense mutations, five nonsense mutations, three splicing mutations, and three frame-shift mutations, among which, c.929insC (29%, 28/96) was the most frequent mutation, followed by c.896G>A (11%, 11/96), c.832C>T (8%, 8/96) and c.703T>C (5%, 5/96). The diagnosis was confirmed in all 16 fetuses in the 16 families that underwent prenatal diagnosis. Five of them were affected and their mothers chose to terminate the pregnancies, the other 11 pregnancies continued to delivery, including seven heterozygous carriers and four fetuses without the same pathogenic allele as the proband. Maternal contamination was excluded in all prenatal samples using short tandem repeat for linkage analysis. All 11 children were in good health during telephone follow-up one month after birth. Postnatal validations were consistent with the prenatal tests.Conclusions:Genetic diagnosis could accurately identify various types of OCA and help to provide prenatal diagnosis and fertility consultation for subsequent pregnancies.
