OBJECTIVE To explore the clinical efficacy of the Yushen Yangluan Formula in treating diminished ovarian reserve(DOR)with kidney essence deficiency based on mitochondrial energy metabolism and oxidative stress.METHODS A total of 70 pa-tients diagnosed with DOR due to kidney essence deficiency,who visited the gynecology department of Yueyang Hospital of Integrated Traditional Chinese and Western Medicine from September 2023 to June 2024,were selected.The patients were randomly divided into two groups according to the random number table method.The treatment group(35 cases)received the Yushen Yangluan Formula,while the control group(35 cases)received a Chinese herbal placebo,with treatment lasting for 3 months,and during the treatment pe-riod,one case dropped out from each group.Antral follicle count(AFC),traditional Chinese medicine(TCM)syndrome scores,and serum levels of anti-Mullerian hormone(AMH),follicle-stimulating hormone(FSH),luteinizing hormone(LH),estradiol(E2),re-active oxygen species(ROS),and adenosine triphosphate(ATP)levels were compared between the two groups.RESULTS After treatment,the TCM syndrome scores for kidney deficiency in both groups decreased compared to before treatment(P<0.05,P<0.01),with the experimental group showing greater improvement than the control group(P<0.01).Following treatment,the FSH levels in the experimental group decreased compared to before treatment(P<0.05),while AMH levels increased(P<0.05),and the antral follicle count(AFC)also increased significantly(P<0.01),with the experimental group outperforming the control group(P<0.05,P<0.01).After treatment,serum ROS levels in the experimental group decreased(P<0.01),and ATP levels increased(P<0.01),with the experimental group showing superior results compared to the control group(P<0.01).CONCLUSION Yushen Yangluan Formu-la can improve the ovarian function and TCM syndrome score of patients with DOR of kidney essence deficiency type,which may be re-lated to improving mitochondrial energy metabolism and reducing oxidative stress.

Delayed lactation activation is a risk factor for early termination of postpartum breastfeeding with high prevalence and adverse effects on the immediate and long-term growth and development of preterm infants,especially very low birth weight infants.This article reviews the delayed lactation activation,evaluation methods of lactation activation in premature mothers and the intervention measures to shorten the delay of lactation activation,in order to provide the basis for the development of relevant studies and the formulation of effective intervention programs.

Objective:To investigate the expressions of human epidermal growth factor receptor 2 (HER2) in recurrent patients after radical gastrectomy and its correlation with clinicopathologic features and prognosis.Methods:The clinical data of 116 recurrent patients after radical gastrectomy between December 2011 and March 2019 in Fujian Cancer Hospital were retrospectively analyzed. The relationship between HER2 expression of the tissues after radical gastrectomy and clinicopathological features as well as prognosis was also analyzed.Results:HER2 positive rate was 19.8% (23/116) in gastric cancer specimens of 116 patients after radical gastrectomy. HER2 positive rate in highly and moderately differentiated patients with gastric cancer was higher than that in those with poorly differentiated gastric cancer [33.3% (11/33) vs. 14.5% (12/83), χ2 = 5.292, P < 0.05]. HER2 positive rate in patients with lung metastasis was higher than that in patients without lung metastasis [42.1% (8/19) vs. 15.5% (15/97), χ2 = 5.517, P < 0.05]. There were no statistical differences in HER2 positive rate among gastric cancer patients with different gender, age, tumor location, recurrent site, TNM stage, number of metastasis, neurovascular invasion, liver metastasis, local recurrence (all P > 0.05). HER2 expression was not associated with disease-free survival time ( P > 0.05). Conclusion:HER2 expression is associated with the differentiation degree of gastric cancer and the location of distant metastasis, but it can not be used as a predictor for recurrence of gastric cancer.

Objective To investigate the effect of human telomerase reverse transcriptase C27 polypeptide (hTERTC27) over-expression on orthotopic implanted tumor growth which induced by nasopharyngeal carcinoma cells C666-1 in vivo.Methods Stably transfected C666-1 cell lines were used to establish subcutaneously transplanted tumor mouse model.The tumor growth was observed and the tumor growth curve was made by measuring the volumes of tumors every day.HE staining was used to observe the change of histomorphology.The expressions of cleaved Caspase-3,Caspase-9,PARP,bax and bcl-2 were detected by Western blot analysis.Results The in vivo mouse model showed that over-expression of hTERTC27 significantly reduced tumor volume and tumor weight (P ＜ 0.05),and decreased the local muscle infiltration.Over-expression of hTERTC27 significantly up-regulated the expressions of cleaved Caspase-3,Caspase-9,PARP and bax (P ＜ 0.01),and down-regulated the expression of bcl-2 (P ＜ 0.01).Conclusion The results indicate that over-expression of hTERTC27 can obviously inhibit the growth of transplanted tumor in nude mice,which is possibly related to the regulation of bax and bcl-2 expression.

Objective To screen serum biomarkers in patients with hepatocelhlar carcinoma by using surface-enhanced laser desorption and ionization time-of-flight mass spectrometry(SELDI-TOF-MS)technique and to evaluate its clinical implication in the patients whose alpha-fetoprotein were negative in the sera. Methods Proteomic spectra were generated by mass spectroscopy in 112 cases, including 57 cases AFP-negative hepatocellular carcinoma,and 55 cases of healthy control. The consequence was analyzed and the characteristic preteomic peaks was selected by using Biomarker Wizard. Results Seven low expressed potential biomarker were indentified with the mass-to-charge ratio of 4.2×103, 4.1×103, 6.7×103, 5.7×103, 6.5×103, 6.9×103, 5.8×103. The sensitivity for diagnosing hepatic cancer were 88.23 % and specificity was 92.31%. These peaks were not correlated with age, sex, tumor mass size, pathology grading and cirrhosis in hepatocellular carcinoma. Conclusion SELDI-TOF-MS offers a unique platform for the proteomic detection of hepatocellular carcinoma.It also offers an auxiliary diagnosis method to the patients whose alpha-fetoprotein are negative in the serum.
