OBJECTIVETo explore the distribution rules of proximal and distal focus of muscle meridian region in scapulohumeral periarthritis.

METHODSThree hundred and six shoulder joints of affected side were selected in 216 patients of scapulohumeral periarthritis. Under the guidance of muscle meridian theory, with the anatomical characteristics of muscle meridian focuses, the frequency and location where proximal and distal focus appeared were calculated by palpation.

RESULTSThe percentages of the frequency that the focus of muscle meridian of Hand-Yangming, Hand-Shaoyang, Hand-Taiyang, and three yin meridians of hand appeared at proximal points of shoulder joint were 25.6% (1 146/5 657), 30.9% (1 749/5 657), 19.0% (1 075/5 657), and 24.5% (1 387/5 657), respectively, the focuses of muscle meridian region were Jianyuci, Juguci, Xiaoshuoci, Naohuici, etc. The percentages of the frequency that the focus of muscle meridian region appeared at distal points of shoulder joint were 31.77% (287/905), 23.2% (210/905), 10.9% (99/905), and 34.1% (304/905), the focuses of muscle meridian were Yangxici, Shousanlici, Yangchici, etc.

CONCLUSIONThe location and frequency of proximal and distal focus of muscle meridian in scapulohumeral periarthritis are closely related with the anatomical structure and biomechanical characteristics of the shoulder joints, thus new therapy for scapulohumeral periarthritis is implied.

In this paper, a low-cost PC-based, high-quality and interactive 3D stereoscopic medical visualization system is presented, which can be clinically used for diagnosis and surgical planning. The algorithms of direct volume rendering have been improved for realization with the programmable graphics hardware under PC environment. Local illumination, classification and non-polygonal iso-surface rendering are also incorporated into the system in appropriate consideration of both high-quality rendering and real-time interaction. The medical visualization system has been applied to the neurosurgical and orthopedic planning and the effectiveness has been clinically proved.

miR-200c has been shown to regulate the epithelial-mesenchymal transition (EMT) by inhibiting ZEB1 and ZEB2 expression in breast cancer cells. This study further examined the role of miR-200c in the invasion and metastasis of breast cancer that goes beyond the regulation on ZEB1 and ZEB2 expression. In this study, the bioinformatics software (miRanda) was used to predict the target gene of miR-200c and Renilla luciferase assay to verify the result. The metastatic breast cancer cells MDA-MB-231 were cultured and transfected with the miR-200c mimic or inhibitor. The expressions of miR-200c and HMGB1 were detected by RT-PCR and Western blotting, respectively. Transwell assay and wound healing assay were employed to examine the invasive and migrating ability of transfected cells. Target prediction and Renilla luciferase analysis revealed that HMGB1 was a putative target gene of miR-200c. After transfection of MDA-MB-231 cells with the miR-200c mimic or inhibitor, the expression of miR-200c was significantly increased or decreased when compared with cells transfected with the miR-200c mimic NC or inhibitor NC. Moreover, the expression of HMGB1 was reversely correlated with that of miR-200c in transfected cells. Tranwell assay showed that the number of invasive cells was significantly reduced in miR-200c mimic group when compared with miR-200c inhibitor group. It was also found that the migrating ability of cells transfected with miR-200c mimics was much lower than that of cells transfected with miR-200c inhibitors. It was suggested that miR-200c can suppress the invasion and migration of breast cancer cells by regulating the expression of HMGB1. miR-200c and HMGB1 may become useful biomarkers for progression of breast cancer and targets of gene therapy.

Objective To explore the problems and countermeasures of special diagnosis support during base training.Methods The problems were analyzed in the allocation of special diagnosis equipment,equipment application in training,special diagnosis technician as well as the cooperation between personnel,equipment and etc,and some countermeasures were proposed accordingly.Results The special diagnosis support gained disadvantage in medical ultrasonic equipment while advantage in ECG machine.Field medical unit had medical technicians decreased after the new organization was implemented,and could meet the requirements after arrangement and strengthening communication facility.Conclusion The special diagnosis technicians in the field medical unit have to enhance their skills on medicine and field first aid.Medical ultrasonic equipment and ECG machine should be equipped in the field medical unit.The intra-and inter-group cooperation should be improved to facilitate special diagnosis support in the field medical unit.

OBJECTIVETo evaluate the bone-implant interfaces of two kinds of implants with different surfaces in different time in vivo.

METHODSCDIC and ITI-TPS solid-screw cylinder pure titanium implants were selected and implanted in the regions of posterior molars of rhesus monkeys. 1 month, 2 months, 3 months and 1 year after surgery, the bone-implant interfaces were evaluated respectively through oral examination, X-ray inspection, light microscope and scanning electron microscope (SEM) observation.

RESULTSNone of the implants was loose. Soft tissue around implants appeared no inflammation. There were no apparent transparent shadow around the implants interfaces in X-ray photos except little angle-shaped absorption was showed in neck region of CDIC implants of one-month. New bone was observed around implants of one-month through light microscope and SEM. More bone growing around ITI implants were seen than that around CDIC implants except the interfaces of one-year.

CONCLUSIONThe osseointegration of ITI implants are better than that of CDIC implants during three months after implanting without loading. The bone formation at the interfaces of ITI and CDIC implants has no significant difference after one year without loading.

Objective To develop a supporting pole for medical detachable camouflage net at field conditions to enhance the timeliness of battlefield camouflage of deployable units such as medical tent.Methods The pole had a dumbbell-shaped,hollow and columnar structure,which was composed of a base,a pole body and a terminal disc.The pole body consisted of internal and external parts.The external part had a vertical opening at its top and screw thread at its side wall,which was equipped with a binding bolt.The terminal disc had a circular structure and a 20 cm outer diameter,which was fixed 10 cm under the top of the internal pole to support the net.The base had a center hole and a sleeve to hold the lower part of the external pole to immobilize the supporting pole.Results The supporting pole decreased the deployment time of the camouflage net from 5 min to 2 min and the withdrawal time from 4 min to 1.5 min,and enhanced the timeliness of all-element deployment of mobile medical unit during field practical training.Conclusion The supporting pole meets the tactical requirements for deployment,storage,transport and robustness,and thus is worthy promoting in medical unit.

OBJECTIVETo explore the clinical significance of serum free light chain (sFLC) levels in nonsecretory multiple myeloma (NSMM).

METHODSNine NSMM patients were hospitalized in our department from Feb 2002 to Sep 2006 and no M-components was found in their serum and urine by immunofixation electrophoresis (IFE). sFLC was assayed by immuno-nephelometry. The clonality of sFLC was estimated by serum kappa:lambda sFLC ratio. Meanwhile, serum immunoglobulin, total kappa and lambda light chain level were also determined in these patients.

RESULTSIncreased serum concentrations of either kappa or lambda sFLC (and abnormal kappa/lambda ratios) were detected in 6 of 9 patients with NSMM although their serum immunoglobulin levels were not elevated and total kappa:lambda light chain ratios (1.32 - 2.20) were in the reference range. All the 9 patients had clonal IgH gene rearrangements.

CONCLUSIONQuantification of sFLC by immuno-nephelometry is more sensitive than that of serum total light chain measurement and is helpful in estimating the clonality of the light chain in patients with NSMM.
