OBJECTIVETo analyse the effect of the reduction of multiple pregnancy through transvaginal ultrasonic monitoring on the pregnancy outcome.

METHODSEighty-four cases were divided into two groups according to whether they had vaginal hemorrhage before operation. And the pregnancy outcomes were analyzed.

RESULTSThe abortion rate and preterm birth rate of the vaginal hemorrhage group were higher, and the difference was statistically significant.

CONCLUSIONSThe reduction of multiple pregnancy through transvaginal ultrasonic monitoring is a safe operative method. But it is only a remedial treatment for multiple pregnancy, and how to prevent multiple pregnancy is of more practical value.

Patients with early cataract may have normal visual acuity ( VA ) but complain that they have problems in driving at night, like seeing things through a veil. This phenomenon is defined as disability glare which maybe caused by growing stray light. Patients with intraocular lens following cataract surgery may complain about glare, halos and shadows in visual field, which are also resulted from dysphotopia. Disability glare is the VA loss due to disturbing luminance in visual field. ln other words, it's the retinal contrast sensitivity reduction because of the straylight. This article contains the consensus and new progress of disability glare. lt provides solutions according to its effect factors and offers clues for further study.

LRP16 is a novel gene which was found in our laboratory by using methylation-sensitive restriction landmark genomic scanning (RLGS) technique. In order to clone the full-length cDNA of this leukemia relapse associated gene, the method of rapid amplification of cDNA end (RACE) was employed. By optimizing some procedures of RACE method, the 5'- and 3'-untranslated region of LRP16 cDNA was successfully sequenced. Then, the full length of LRP16 cDNA and open reading frame (ORF) was constructed and was registered in GenBank. The above-mentioned procedure demonstrated RACE technique is a rapid and sensitive method for cloning unknown gene. Especially, it is very useful to cloning the 5'- and 3'-untranslated region of a novel gene.

Chloride channels belong to a superfamily of ion channels that permit passive passage of anions, mainly chloride, across cell membrane. They play a variety of important physiological roles in regulation of cytosolic pH, cell volume homeostasis, organic solute transport, cell migration, cell proliferation, and differentiation. However, little is known about the functional regulation of these channels. In this study, we generated an integrated transgenic worm strain expressing green fluorescence protein (GFP) fused CLC-type chloride channel 1 (CLH-1::GFP), a voltage-gated chloride channel in Caenorhabditis elegans (C. elegans). CLH-1::GFP was expressed in some unidentified head neurons and posterior intestinal cells of C. elegans. Interacting proteins of CLH-1::GFP were purified by GFP-Trap, a novel system for efficient isolation of GFP fusion proteins and their interacting factors. Mass spectrometry (MS) analysis revealed that a total of 27 high probability interacting proteins were co-trapped with CLHp-1::GFP. Biochemical evidence showed that eukaryotic translation elongation factor 1 (EEF-1), one of these co-trapped proteins identified by MS, physically interacted with CLH-1, in consistent with GFP-Trap experiments. Further immunostaining data revealed that the protein level of CLH-1 was significantly increased upon co-expression with EEF-1. These results suggest that the combination of GFP-Trap purification with MS is an excellent tool to identify novel interacting proteins of voltage-gated chloride channels in C. elegans. Our data also show that EEF-1 is a regulator of voltage-gated chloride channel CLH-1.

OBJECTIVETo explore the efficacy on knee osteoarthritis (KOA) treated with different acupuncture methods at different stages.

METHODSOne hundred and eighty cases of KOA were divided into stagnation stage, fascia cramp stage and tendon lesion stage according to the condition of disease, 60 cases in each stage. Each stage was randomized into a staging treatment group and an electroacupuncture (EA) group, 30 cases in each one. In the staging treatment group, acupuncture at the tendon points of meridians and electric thermal needling method were adopted for the cases at the stagnation stage; the small needle-knife therapy and bleeding method were used for the cases at the fascia cramp stage; and the electric thermal therapy with thick silver needles was applied for the cases at the tendon lesion stage. In the EA group, EA was applied for the cases of all the three stages at Liangqiu (ST 34), Xuehai (SP 10), Yanglingquan (GB 34), etc.

RESULTSThe total effective rate was 96.1% (87/90) in the staging treatment group and was 91.1% (82/90) in the EA group, without significant difference in comparison (P > 0.05). The controlled and remarkably effective rate (88.9%, 80/90) in the staging treatment group was higher apparently than (62.2%, 56/90) in the EA group (P < 0.001). And in the EA group, with the disease progression and the further disease stages, the controlled and remarkably effective rate was reduced. After treatment, the scores of symptoms and signs were decreased in both groups (both P < 0.001), the improvement in the staging treatment group was superior to that in the EA group (P < 0.001).

CONCLUSIONThe different acupuncture methods at the three stages improve obviously the clinical effect and are highly targeted. The mechanism of the three stages on "meridian muscle region pathology" and the treatment based on the disease stages can be the effective approach to KOA.
