Mitochondrial calcium homeostasis plays a key role in maintaining various cellular characteristics and mediating cellular physiological function and pathological processes .Although it has long been known that mitochondria takes up Ca2+, the molecular identities of the channels and transporters involved in this process are revealed only recently . Here, we review the structure and function of the channel-forming subunit, mitochondrial calcium uniporter (MCU) and its regulators, which include MICU1, MICU2, and MCUR1.

Dry age-related macular degeneration(AMD)is a prevalent form of irreversible blindness worldwide in the elderly population with an increasing incidence in China.It is found that some dry AMD will develop to wet AMD and therefore damage visual function.Pathogenesis of AMD is below understand now,but it is thought to be related to the light-induced ocular damage,oxidative stress response,extracellular disposition and immunology.Up to now,effective and safe prevention and treatment methods of AMD are still studying,especially wet AMD,but the concern on dry AMD is not enough.Some basic and clinical pharmaceutics researches on AMD include antioxidants,anti-extracellular disposition drugs and anti-inflammatory agents.With the rise of aging population,we should pay special attention to the research on pathogenesis,diagnosis and treatment of dry AMD.

Objective To evaluate the clinical value of infusing dehydrated alcohol on pancreatic pseudocyst (PPC). Methods Twenty one patients with D'Egidio type I PPC underwent CT or ultrasound (US) guided percutaneous catheter drainage, and CT or US were used to re-evaluate the efficacy of drainage. If no residual cavity was observed, the drainage tube was clamped for 3~7 d, and then the tube would be pulled out. Non-curative cases with catheter drainage for 21 days were given dehydrated alcohol 20 ml infusion. Results The curative rate by using percutaneous catheter drainage was 71.43% (15/21). Among the remaining 6 patients, the treatment was effective in 3 patients and ineffective in other 3 patients. 2 cases of non-infective mutli-antrum pancreatic pseudocyst, 1 case of infective single antrum and 3 cases of infective multi-antrum were included in the 6 non-curative cases, and all of them recovered completely 6~21 d after dehydrated alcohol infusion. No complication and recurrence were found during the 6~12 follow-up. Conclusions Percutaneous puncture and dehydrated alcohol infusion for infective or mufti-antrum pancreatic pseudocyst was effective and safe.

Objective To explore changes of risk factors between premenopausal and postmenopausal female patients with coronary heart disease (CHD). Methods A total of 283 female patients were divided into CHD group (n=154) and con?trol group (n=129) according to whether they suffered from CHD or not. Patients were further stratified into two groups accord?ing to menopausal situation:premenopausal group (n=78, including premenopausal CHD group of 34 cases and premenopaus?al control group of 44 cases) and postmenopausal group (n=205, including postmenopausal CHD group of 120 cases and post?menopausal control group of 85 cases). Clinical data of age, body mass index (BMI), medical history and menses situation were recorded. The levels of cholesterol (CHO), triglycerides (TG), high density lipoprotein cholesterol (HDL-C), low density lipo?protein cholesterol (LDL-C), very low density lipoprotein cholesterol (vLDL-C), apolipoprotein AI (ApoAI), apolipoprotein B (apoB), lipoprotein a (Lpa), homocysteine (HCY) and high-sensitive C-reactive protein (hsCRP) were also detected. Results There were significantly higher levels of age, CHO, TG, LDL-C, vLDL-C, Lpa, ApoB, hsCRP, and the ratio of hypertension history, diabetic history, coronary heart disease family history in CHD group than those of control group. The level of HDLc was significantly lower in CHD group than that of control group. The ratio of hypertension history, diabetic history and levels of CHO, TG, LDL-C, vLDL-C, Lpa, ApoB, hsCRP were significantly higher in both premenopausal and postmenopausal CHD groups than those of their control groups. The level of HDL-C was significantly lower in postmenopausal CHD group than that of postmenopausal control group (P<0.05). Hypertension history, diabetic history and LDL-C were the independent risk fac?tors of premenopausal CHD. Hypertension history, diabetic history and CHO were the independent risk factors of postmeno?pausal CHD, and HDL-C was the protecting factor of CHD. The ratio of hypertension history, the level of CHO and LDL-C were significantly higher in postmenopausal CHD group than those of premonopausal CHD group. Conclusion The abnor?mal blood pressure level and dyslipidemia are more prevalent in postmenopausal female patients with CHD than premeno?pausal female patients. We should control these risk factors to improve the prognosis.

Objective To study the value of laparoscopy in the diagnosis and treatment of infertility caused by fallopian tube factors. Methods 210 cases of infertility women caused by fallopian tube factors were studied in terms of adhesiolysis,fallopian tube plasty,fenestration,and patency test were performed.The pregnancy rate was followed up for one year. Results The false negative rate in the diagnosis of fallopian tube patency was 5.43% by hysterosalpingography.It was found that there were 3 cases of genital tract tubercle,80 cases of fallopian tube inflammation,73 cases of inflammation of fallopian tube and overy and 54 cases of hydrosalpingix.Of the later 3 kinds,pelvic inflammation was found to be responsible for 120 cases(57.1%),pelvic endometriosis for 87 cases(41.4%).The pregnancy rate after one year was 50.9%(78/153)for inflammation of fallopian tube and ovary,5.6%(3/54)for hydrosalpingix,respectively. Conclusions Laparoscopy helps to clarify infertility caused by fallopian tube factors,and to improvel the effect of treatment and pregnancy rate.

Objective To observe and evaluate the effect of ultrasound guided percutaneous ethanol injection for hyperparathyroidism secondary to chronic renal failure. Methods Fifty-three patients with secondary hyperparathyroidism in Nanjing General Hospital Military Command from January 2011 to May 2013 were treated by percutaneous ethanol injection. The echogenicity, size and blood supply of parathyroid glands were observed by color Doppler ultrasound before and after treatment. Parathyroid hormone (PTH) and volumes of parathyroid glands were analyzed and compared with non-paired t test. Results Before treatment, the parathyroid gland volume was (5.28±0.84) cm3. The enlarged parathyroid glands had homogeneous hypoechogenicity and abundant blood supply, and the PTH was (1041.6±37.1) ng/L. After treatment, the size of solitary parathyroid gland was (3.93±0.67) cm3 which did not change significantly compared with that before treatment. The echogenicity of parathyroid glands enhanced and blood supply decreased after injection ethanol into solitary parathyroid. PTH [(509.2±27.6) ng/L] decreased obviously (t=3.792, P < 0.05). Conclusion Color Doppler ultrasound guided percutaneous injection of ethanol has an important role in the treating of secondary hyperparathyroidism and the curative effect can be observed timely.
