Objective To evaluate the therapeutic responses to transsphenoidal surgery and medical therapy in terms of normalization of prolactin(PRL),mortality,morbidity and the cost-effectiveness of PRL normalization in order to establish an individualized therapeutic protocol for the patients with prolactinoma.Methods A retrospective study was undertaken of a consecutive series of patients with prolactinoma who were followed for at least 1 year after transsphenoidal surgery or medical treatment.The clinical characteristics and the long-term outcomes(normalization of PRL,morbidity or mortality)were assessed.Utilizing the principle of medical economics and data from the two types of treatment,we worked out a Markov chain and calculated the lowest cost of two kinds of therapeutic protocols.Results(1)The success rate of normalizing serum PRL through surgical treatment in microadenoma was 85%(22/26),and that of medical treatment was 95%(19/20).There was no statistical difference between the two therapies(P>0.05).The success rate of normalizing serum PRL through surgical treatment in macroadenoma was45%(19/42),and that of medical treatment was 5/5.There was a statistical difierence between the two therapies(P<0.05).(2)According to the Markov model,it would cost a microprolactinoma patient 25 129.25 yuan to normalize serum PRL by surgical treatment.This is comparable to the cost of medical treatment which would be 24 943.99 yuan.Whereas for a macroprolactinoma patient surgery would cost 35 208.20 yuan and medical treatment would cost 25 344.38 yuan.Conclusions Medical therapy is superior to surgical treatment in regard to complication rate and cost-effectiveness for macro-and extra big prolactinomas.Transsphenoidal surgery remains an option for patients with microadenomas.Markov model is an effective way to predict the treatment cost for patients with hyperprolactinoma at different ages and with different canses

Objective:To evaluate the relationship between red blood cell distribution width (RDW) and metabolic syndrome (MS) in patients with impaired glucose tolerance (IGT).Methods:A total of 415 patients with abnormal glucose tolerance were screened by oral glucose tolerance test in Changsha Traditional Chinese Medicine Hospital (Changsha Eighth Hospital) from October 2015 to September 2019. General data were collected and blood routine and biochemical indexes were detected. There were 193 cases in the observation group and 222 cases in the control group. The RDW and other clinical indicators were compared between the two groups, the correlation between RDW and other indicators was analyzed, and the risk factors of metabolic syndrome were analyzed.Results:⑴ The RDW, systolic blood pressure (SBP), diastolic blood pressure (DBP), height (Ht), weight (Wt), waist circumferenc (Wc), triglyceride (TG), cholesterol (CHOL), low density lipoprotein (LDL), creatinine (Cr), uric acid (UA), alanine aminotransferase (ALT), high sensitive C-reactive protein (hs-CRP), body mass index (BMI) of the observation group were significantly higher than those of the control group, while the high density lipoprotein (HDL) was significantly lower than that of the control group, with statistically significant difference ( P<0.05); ⑵ correlation analysis showed that RDW was positively correlated with SBP, DBP, Ht, Wt, Wc, TG, CHOL, Cr, UA, ALT, hs-CRP, BMI, and negatively correlated with HDL ( P<0.05); ⑶ binary logistic regression analysis showed that RDW, Wt, Wc, CHOL, HDL, LDL and hs-CRP were independent risk factors for MS in patients with impaired glucose tolerance. Conclusions:The increase of RDW is a predictor of metabolic syndrome in people with abnormal glucose tolerance, which may provide some reference value for the prevention and treatment of metabolic syndrome.

BACKGROUND AND OBJECTIVETraditional Chinese medicine is an approach for malignant tumor treatment with Chinese characteristics. The aim of this study is to investigate the inhibitory effects of Maimendong & qianjinweijing decoction extract on A549 human lung cancer cell line proliferation and explored its probable molecular mechanisms.
METHODSA549 cells were treated with drugs in different does and time. The effects on the proliferation of A549 cells were detected by MTT assay and clonogenic assay in vitro. Cell cycle was analyzed by flow cytometry. Morphological changes of the apoptosis of cancer cells were observed by Hochest 33258 staining. Western blot was performed to detect apoptosis-related gene expression.
RESULTSEthyl acetate extract inhibited the growth of A549 cells but not in HFL-1 cells. Compared with controls, administration of 10 microg/mLethyl acetate extract resulted in 73.86% decrease in colony formation (P < 0.01), apoptotic rates of 33.86% (P < 0.01), and morphological changes of apoptosis in A549 cells. The expression of anti-apoptotic protein EGFR and ERK were significantly down-regulated (P < 0.01).
CONCLUSIONEthyl acetate extract might inhibit proliferation and induce apoptosis in A549 cells via downregulation of EGFR/ERK signal transduction pathway. Therefore, ethyl acetate extract should be further separated in order to identify the material fundamentals on anti-cancer effect.

Objective To investigate the effects of telmisartan and pyridoxamine on vascular smooth muscle cells (VSMCs) proliferation and apoptosis as well as abdominal aorta vascular remodeling in spontaneously hypertensive rats (SHRs). Methods SHRs randomly received placebo, telmisartan(6 mg*kg-1*d-1), pyridoxamine(200 mg*kg-1*d-1) or telmisartan (6 mg*kg-1*d-1) plus pyridoxamine (200 mg*kg-1*d-1, n=12 each) for 16 weeks. Wistar-Kyoto (WKY, n=12) rats serve as normotensive contro1. The systolic blood pressure (SBP) of rat was measured before and weekly thereafter. The serum advanced glycation end-products (AGEs) were detected by competitive ELISA. The serum super oxide dismutase (SOD) and nitric oxide (NO) were measured. The abdominal aorta were assessed by image analysis in HE stained sections. The VSMCs apoptosis and proliferation in abdominal aorta were detected with in situ end labeling technique and proliferating cell nuclear antigen (PCNA) immunohistoehemistry staining respectively. Results SBP were significantly lower in telmisartan and telmisartan plus pyridoxamine therapy group than in placebo treated hypertensive rats while not affected by pyridoxamine (P>0.05). Activity of SOD and NO were significantly higher and AGEs significantly lower in telmisartan, pyridoxamine and combination therapy treated SHRs than in placebo treated hypertensive rats(P<0.01). The elmisartan, pyridoxamine and combination therapy can significantly inhibit the PCNA expression and significantly enhance the apoptosis value in abdominal aorta(P<0.01). The efficacy of combined treatment was significantly higher than telmisartan and pyridoxamine alone(P<0.05). Conclusion Telmisartan and pyridoxamine could attenuate abdominal aorta vascular remodeling via reducing oxidative stress and AGEs production as well as restoring the balance of VSMCs proliferation and apoptosis in SHRs abdominal aorta.
