Objective To assess the clinical feature and diagnosis of diffuse hyperpigmentation with guttate depigmentation macules.Methods A retrospective study was carried out among 10 patients with diffuse hyperpigmentation with guttate depigmentation macules collected at the Institute of Dermatology,Chinese Academy of Medical Sciences and Peking Union Medical College from 2005 to 2012.The clinical manifestations,pathological findings and disease outcomes in these patients were analyzed.Results Of the 10 patients,6 were male,and 4 were female.The median age at onset was 7 years (range,4-25),and there were only 3 adult patients among these patients.None of the patients had a family history of pigmentary disturbance.Typical clinical manifestations included densely distributed,guttate hypopigmented macules arising on diffuse and uniform hyperpigmentation.Lesions could slowly spread over the body surface without the trend towards spontaneous regression.Pathologically,there was a slight increase in pigmentation of the epidermal basal layer,as well as melanins and melanophages scattered around blood vessels in the superficial dermis,with or without focal vacuolar degeneration of the basal cell layer.Conclusions Diffuse hyperpigmentation with guttate depigmentation macules,a rare pigmentary disturbance that clinically manifests as both hyperpigmentation and hypopigmentation and is pathologically characterized by postinflammatory hyperpigmentation,often affects children.Once the lesions occur,there is no trend towards regression.No effective treatment is available for this entity at present.

Objective To investigate the safety and feasibility of carotid artery stenting (CAS) and evaluate its clinical outcomes. Methods From July 1998 to December 2003, 30 consecutive patients with 32 lesions underwent extracranial CAS procedures. Thirteen patients had a history of stroke or TIAs, 22 were hypertensive, 11 were diabetic and 8 had history of MI. Neurological assessment, Carotid duplex ultrasound, carotid and intracranial angiography were done before CAS in all patients. All the cases were done percutanously from femoral arteries and stenting was applied in all procedures. Carotid duplex ultrasound, cardiac and neurological elevation were performed post procedure. Results 30 patients (26 male and 4 female) underwent a total of 32 CAS procedures. Total 32 self-expandable stents and 1 tubular stent were implanted in all the cases. Direct stenting technique was applied in 9 cases. The other 21 procedures were performed with distal filtration supporting devices. The device can not be delivered due to tortuous target vessel in one case (success rate 95%) and CAS success rate was 97%. The particles were found in all filter baskets. Four patients underwent coronary artery bypass grafting 1 month later post CAS without perioperative neurological and cardiac events. One patient had contralateral cerebral hemorrhage during CAS and died three days later. Another patient died three days after CAS due to acute pulmonary edema. No restenosis was found by means of carotid duplex ultrasound during the follow-up (3-60 months) study. Conclusion CAS is safe and feasible in preventing ischemic stroke. This new alternative has satisfied clinical outcomes in managing cardiac and neurological ischemic diseases. Operative embolic complication can be potentially prevented by neurological protective device.

This study examined in vitro effect of lipoxin A(4) (LXA(4)) on interleukin-1β (IL-1β) production of monocytes and its possible mechanism in severe preeclampsia (PE). Peripheral venous blood was drawn from 15 patients with severe preeclampsia (PE group) and 20 normal pregnant women (control group) to prepare monocytes which were then treated with LXA(4) at different concentrations of 0, 10, 100 nmol/L respectively. IL-1β level in the supernatant of monocytes was detected by enzyme linked immunoassay. The [Ca(2+)](i) of monocytes was measured by laser scanning confocal microscopy. The results showed that the IL-1β level and the [Ca(2+)](i) of monocytes in the PE group were significantly higher than those in the control group. LXA(4) significantly decreased the generation of IL-1β in a dose-dependent manner in the PE group. After treatment with 100-nmol/L LXA(4), in the PE group, the [Ca(2+)](i) concentration of monocytes was significantly reduced. It was concluded that LXA(4) may inhibit the IL-1β production of monocytes from severe preeclampsia women by inhibiting extracellular calcium influx.

Abtract: Acute coronary syndrome is a common clinical and frequently occurring disease, belonging to the chest discomfort, heartache, and true heart pain of TCM category. The clinical observation shows that the heat and blood stasis, and poison damage heart nutrient is one of the important mechanisms of triggering coronary syndrome. Therefore, the method of promoting blood circulation to remove meridian obstruction and the Qing Ying detoxication was established as the basic treatment, and Danshen Tongluo Jiedu Decoction is applied as the main formula. According to the different types of disease and syndrome differentiation, flexible modification can achieve good efficacy. It is expected that these will provide new ideas and methods for clinical treatment of acute coronary syndrome.

Objective To investigate the distribution of folliclestimulating hormone (FSH),luteinizing hormone (LH) and colocalization with gonadotropin releasing hormone receptor (GnRHR) in rat submaxilary glands. Methods Distribution of FSH, LH and colocalization with GnRHR consecutive sections of rat submaxilary glands were investigated by immunohistochemical colocalization methods. Results FSH and LH immunoreactivity were observed in the epithelial cells of serous acinus, secretory tubes, excretory ducts and granular convoluted tubule. The immunoreactive materials were brown and distributed in the cytoplasma with negative nucleolus. The results of immunohistochemical colocalization showed not only FSH but also GnRHR immunoreactivity in the same structure of two adjacent section. The distribution of the positive substance of FSH and GnRHR were similar to each other. The most of showing GnRHR immunoreactivity cells were detected LH immunoreactivity in the same structure of two adjacene section and the others were immunonegative. The GnRNR immunoreactive materials were distributed in the cytoplasma with negative nucleolus.Conclusion The epithelial cell of serous acinus, secretory tubes, excretory ducts and granular convoluted tubule of rat submaxilary glands may be synthesized and secreted FSH and LH. These cells with FSH and LH positive immunoreaction of rat submaxilary glands may be regulated by Gonadotropin releasing hormone (GnRH) through autocrine or paracrine.;
