OBJECTIVE:
A case of half sibling was determined with multiple genetic markers, which could be potentially applied for determination of half sibling relationship from same father.
METHODS:
Half sibling relationship was detected by 39 autosomal STR genetic markers, 23 Y-chromosomal STR genetic markers and 12 X -chromosomal STR genetic markers among ZHAO -1, ZHAO -2, ZHAO -3, ZHAO -4, and ZHAO-5.
RESULTS:
According to autosomal STR, Y-STR and X-STR genotyping results, it was determined that ZHAO-4 (alleged half sibling) was unrelated with ZHAO-1 and ZHAO-2; however, ZHAO-3 (alleged half sibling), ZHAO-5 (alleged half sibling) shared same genetic profile with ZHAO-1, and ZHAO-2 from same father.
CONCLUSION
It is reliable to use multiple genetic markers and family gene reconstruction to determine half sibling relationship from same father, but it is difficult to determination by calculating half sibling index with ITO and discriminant functions.

OBJECTIVE To provide technical support for improving recognition rate of adverse drug events (ADEs) related to traditional Chinese medicine (TCM) formula granules and decoction pieces among inpatient patients. METHODS By referencing the global trigger tool (GTT) whitepaper, literature on adverse reactions to TCM, and expert review opinions, ADE trigger items for TCM formula granules and decoction pieces used in the inpatients were established. GTT was applied to analyze ADEs in inpatients who had used TCM formula granules and decoction pieces in our hospital from August 2013 to August 2023, utilizing the Chinese Hospital Pharmacovigilance System. The effectiveness of GTT and the characteristics of these ADEs were analyzed. RESULTS A total of forty-eight triggers were established, including thirty-two laboratory test indexes, thirteen clinical symptoms, and three antidotes. Among the 1 682 patients included, GTT identified 652 potential ADEs, 284 true positive ADEs,with a trigger rate of 38.76% and a positive predictive value of 43.56%. After review by the auditor, 278 cases of ADEs were finally confirmed, with an incidence rate of 16.53%, significantly higher than the number of spontaneously reported ADEs during the same period (0). The 278 cases of ADEs were mostly grade 1 (223 cases), mainly involving hepatobiliary system, gastrointestinal system, blood- lymphatic system, etc;a total of 219 types of TCMs are involved,and the top five suspected TCMs used at a frequency higher than 1% were Poria cocos, Codonopsis pilosula, Atractylodes macrocephala, fried Glycyrrhiza uralensis, and Scutellaria baicalensis. CONCLUSIONS The established GTT can improve the recognition rate of ADEs for hospitalized patients using traditional Chinese medicine formula granules and decoction pieces.

OBJECTIVETo investigate the regulatory effect of miR-181a with abnormal expression on the expression of c-fos in cochlear hair cells undergoing oxidative damage.
METHODSHouse Ear Institute-Organ of Corti1 (HEI-CO1) cells were assigned to 50, 100, and 200 µmol/L tert-butyl hydroperoxide (t-BHP) exposure groups and control group. The HEI-CO1 cells in the exposure groups were exposed to 50, 100, or 200 µmol/L t-BHP for 12 h. Then, total RNA and total protein were extracted from the HEI-CO1 cells, and the expression of miR-181a/-181d was measured by qPCR. The miR-181a with abnormal expression was selected as the subject of study. The putative miR-181a target sequence in the 3' untranslated region (3'-UTR) of c-fos was predicted by searching on a bioinformatics website. The HEI-CO1 cells were transfected with miR-181a mimics by lipofection, and the transfection efficiency was measured by qPCR. The mRNA and protein expression of c-fos was measured by qPCR and Western blot. The pGL3-c-fos-3'UTR-WT plasmid was constructed, and the luciferase activity of the plasmid in the case of high miR-181a expression was measured using the Dual-Luciferase Reporter Assay System.
RESULTSCompared with those in the control group, the expression of miR-181a in 100 and 200 µmol/L t-BHP exposure groups was significantly decreased, with expression ratios of 0.744 and 0.766 (P < 0.01), while the expression of miR-181d in 50 µmol/L t-BHP exposure group was significantly increased, with an expression ratio of 1.29 (P < 0.01). There was no significant difference in miR-181a expression between the 100 and 200 µmol/L t-BHP exposure groups (P > 0.05). The predication results revealed that c-fos was regulated by miR-181a in humans and mice, with complete complementarity to the seed region of miR-181a, and there was high degree of target sequence conservation across species. The expression of miR-181a in the HEI-OC1 cells transfected with miR-181a mimics was elevated 892.979 times at 24 hours after transfection. As compared with those of controls, the mRNA and protein expression levels of c-fos in the transfected HEI-OC1 cells were significantly increased (P < 0.05 and P < 0.01). The luciferase activity of pGL3-c-fos-3'UTR-WT plasmid was not suppressed but increased in the case of high miR-181a expression.
CONCLUSIONmiR-181a has no direct inhibitory effect on the mRNA and protein expression of c-fos, which may not be the target gene of miR-181a. Bioinformatic prediction might produce false-positive results.

ObjectiveTo investigate the quality of life (QOL) of the epilepsy patients and the factors affected the QOL.Methods200 cases were investigated using the Quality of Life in Epilepsy Inventory 10 (QOLEI-10) and the Washington Psychosocial Seizure Investigate (WPSI). 200 healthy persons were chosen as normal control group. ResultsThe QOL of the patient group were significantly poor as compared with that of normal control group(P<0.01). The factors that the patients always faced with were disability in the attack control, short in money, unemployment, restriction of movement, disability in intercommunication, psychological disorder (depress, strain, anxiety, dread, shame feel, cognitional dysfunction, etc.), as well as the difficult to get professional curtains, taking medicine improperly and side effects of the medicine. Conclusions The factors mentioned, which were usually neglected by many doctors, do affect the QOL of epilepsy patients, and hinder the epilepsy treatment effectively.

ObjectiveTo investigate the clinical efficacy of oral dydrogesterone alone for luteal phase support in natural cycle frozen-thawed embryo transfer (NC-FET). MethodsThe clinical data of 1 530 NC-FET cycles enrolled in our Reproductive Center from January 2019 to September 2021 were retrospectively analyzed. According to different luteal support protocols, the patients were divided into oral dydrogesterone alone (group A, n=524), vaginal progesterone soft capsules (group B, n=401) and vaginal progesterone soft capsules combined with dydrogesterone (group C, n=605). The clinical outcomes and cost-effectiveness ratio were compared among the three groups. The primary outcome was live birth rate. ResultsThe live birth rate was 43.13% (226/524) in group A, 39.15% (157/401) in group B, and 42.64% (258/605) in group C. There was no statistical difference among the three groups (P > 0.05). No statistical difference was observed in the HCG positive rate, implantation rate, biochemical pregnancy rate, clinical pregnancy rate, spontaneous miscarriage rate, ectopic pregnancy rate, twin delivery rate, premature delivery rate and newborn weight among the three groups (P>0.05). Logistic regression analysis revealed that the three luteal support regimens did not affect live birth rate. Pharmacoeconomic analysis showed that taking group B as a reference, the cost increased by 19 227.30 yuan for every 1% increase in live birth rate in group A. ConclusionsIn NC-FET cycle, oral dydrogesterone alone can achieve the same clinical outcomes as vaginal progesterone soft capsules and vaginal progesterone soft capsules combined with dydrogesterone. Compared with that of progesterone soft capsules, the cost of oral dydrogesterone alone is increased, a large sample and multicenter prospective study is needed to further confirm our results.

OBJECTIVE: To evaluate the effect of Kuntai capsule on the gonadotrophin releasing hormone agonist(GnRH-a)-induced perimenopaus symptoms and the sex hormone levels.METHODS: A total of 99 patients with uterine fibroids,adenomyosis or moderate to severe endometriosis who needed the treatment of GnRH-a at Sun Yat-sen Memorial Hospital of Sun Yat-sen University from June 2015 to March 2016 were collected and randomly divided into research group(Kuntai capsule)and control group(Tibolone). GnRH-a was injected once every 28 days and first injection of GnRH-a was administered on the 2 nd to 4 th day of menstrual period or retraction bleeding after surgery.Kuntai capsule or Tibolone was orally taken beginning from the first GnRH-a injection,and the co-administration of Caltrate D-600 and alfacalcidol was given in both groups.The Kupperman scores,sex hormone levels including folliclestimulating hormone(FSH)and estrogen(E_2),and adverse events were recorded.RESULTS: Kuntai capsule kept the perimenopause symptoms at mild level with the slow increase of Kupperman scores,whose effect was significantly superior to Tibolone(P<0.05)after 8 weeks of treatment,especially in paresthesia,nervousness,and formication.The FSH and E_2 levels in both Kuntai and Tibolone groups were obviously decreased when compared with the pre-treatment(P<0.05),and these hormone levels in Kuntai group were comparable to those in Tibolone group.No adverse events occurred in either group. CONCLUSION: In the short-term treatment of GnRH-a,Kuntai capsule exhibits significant alleviating effects on perimenopause symptoms caused by GnRH-a with high safety and few adverse reactions.

OBJECTIVETo investigate clinical characteristics and mutation of the LKB1 gene in a Peutz-Jeghers syndrome (PJS) pedigree.
METHODClinical data of a PJS family were analyzed and LKB1 gene mutation was detected by systematic screening with multiplex ligation-dependent probe amplification (MLPA) and DNA sequencing. Meanwhile, two hundred and fifty healthy adults were enrolled in this study and denaturing high performance liquid chromatography (PCR-DHPLC) was carried out to verify the mutation excluding polymorphism sites found in this family. Changes in protein structure and function caused by the mutated coding sequence was analyzed by SWISS-MODEL software.
RESULTThe proband had pigmented mucocutaneous lesions and multiple hamartomatous polyps in the gastrointestinal tract. There was no fragment deletion of LKB1 gene detected by MLPA. Among PJS family and 250 healthy adults, germline mutation c. 924G > C of LKB1 which cause Trp308Cys in protein sequence was identified only in the proband and another affected member. LKB1 protein activity could be reduced due to changes in LKB1 protein conformation structure by Trp308Cys.
CONCLUSIONPeutz-Jeghers syndrome (PJS) is an autosomal dominant disorder characterised by mucocutaneous pigmentation, multiple gastrointestinal hamartomatous polyps and heredofamilial nature. Gene identification and mutagen screening of LKB1 gene in all PJS patients and first degree relatives will contribute to a definite diagnosis and improve the life span of the family.
