OBJECTIVETo assess the clinical efficacy and the safety for periarthritis of shoulder treated with deep puncture by elongated needle combined with spike-hooked needle and cupping.

METHODSA multicentral randomized controlled study was adopted. One hundred and twenty cases were divided into an observation group and a control group, 60 cases in each one. In observation group, elongated needle, spike-hooked needle and cupping were used to stimulate Jianyu (LI 15), Naoshu (SI 10), Naohui (TE 13) and Jianqian (Extra). In control group, a conventional needling and cupping were applied to the same points as observation group. Visual Analogue Scale (VAS) and Melle evaluation for the function activity of shoulder joint were adopted to assess and compare the efficacy on analgesia and the effect on shoulder joint range of motion before and after treatment in two groups.

RESULTSIn observation group, the cured and markedly effective rate of analgesia was 91.7% (55/60), which was obviously better than 20.4% (12/59) in control group (P < 0.001). Concerning to the improvements of the range of motion in shoulder joint, the cured and markedly effective rate in observation group was 91.7% (55/60), which was better than 18. 6% (11/59) in control group (P < 0.001). VAS score and Melle score after treatment were apparently improved as compared with those before treatment in two groups (all P < 0.001). The improvements in observation group were superior to those in control group (both P < 0.001). There was no adverse event reported during the treatment in two groups.

CONCLUSIONThe deep puncture by elongated needle combined with spike-hooked needle and cupping achieves a significant clinical efficacy on periarthritis of shoulder and has no adverse reaction reported.

OBJECTIVETo investigate whether progesterone receptor B (PRB) can be sumoylated by SUMO-2/3 and the effect of sumoylation on PRB transcriptional activity.

METHODSSUMO-2/3 cDNA was amplified from MCF-7 cDNA and cloned into the eukaryotic expression vector pcDNA3-FLAG. The plasmid pXJ40-myc-PRB was cotransfected with pcDNA3FLAG-SUMO2, pcDNA3FLAG-SUMO3 or the mock control into 293T cells, and PRB sumoylation was detected by immunoprecipitation and Western blotting. The effect of PRB sumoylation on its transcriptional activity was determined using reporter luciferase assay.

RESULTSpcDNA3FLAG-SUMO2 and pcDNA3FLAG-SUMO3 vectors were successfully constructed. SUMO-2/3 could bind covalently to PRB and increase its transcriptional dependent on the presence of progesterone.

CONCLUSIONPRB can be sumoylated by SUMO-2/3 and its function is regulated by this modification.

Parvalbumin interneurons belong to the major types of GABAergic interneurons. Although the distribution and pathological alterations of parvalbumin interneuron somata have been widely studied, the distribution and vulnerability of the neurites and fibers extending from parvalbumin interneurons have not been detailly interrogated. Through the Cre recombinase-reporter system, we visualized parvalbumin-positive fibers and thoroughly investigated their spatial distribution in the mouse brain. We found that parvalbumin fibers are widely distributed in the brain with specific morphological characteristics in different regions, among which the cortex and thalamus exhibited the most intense parvalbumin signals. In regions such as the striatum and optic tract, even long-range thick parvalbumin projections were detected. Furthermore, in mouse models of temporal lobe epilepsy and Parkinson's disease, parvalbumin fibers suffered both massive and subtle morphological alterations. Our study provides an overview of parvalbumin fibers in the brain and emphasizes the potential pathological implications of parvalbumin fiber alterations.
