Objective To quantize the synergistic force in movement of upper limbs between shoulders and elbows. Methods The trans-verse forces of elbows and shoulders during movement were recorded in a healthy adult with an upper-limb-force-measuring plate form which comprised of 2 three-dimensional force sensors, respectively. Then he performed shoulder abduction/adduction and elbow extension/flexion at 100%, 75%, 50%and 25%of the maximum contraction force, respectively. The ratio of the active action force and the joint action force (named assessment index) was used to assess the synergistic degree of the forearm and the upper arm. Results In the shoulder abduc-tion motion, the assessment index decreased as the strength of active action decreased, meant interference of joint action increased. Howev-er, it was almost stable in the shoulder adduction, increased in the elbow extensionas, and was irregular in the elbow flexion, as the active ac-tion strength decreased, respectively. Conclusion It may be more difficult to control upper arm than the forearm.

The processing technology of traditional Mongolian medicine materials is distinctive, and it is one of the main characteristics of Mongolian pharmacy. Most of Mongolian medicines were used in the raw, but a quarter of medicinal materials need to be produced. Since ancient times, the processing of Mongolian medicine have cooperated with the Mongolian medicine clinical, which plays an important role in improving curative effect of Mongolian medicine and ensuring the safety of the drug. At present, the Mongolian medicines are processed still according to the traditional methods of the ancient literature method which has a lot of problems such as lag in technology, method of diversification, ambiguous indicators and unclear mechanism. Standardization of Mongolian medicine processing was based on traditional Mongolian medicine basic theory, which both projecting the characteristic, inheriting the traditional colleagues and reference to modern medicine, pharmacology, toxicology and other disciplines of knowledge. In this article, the processing situation, existing problem and standardization research of Mongolian medicine were described that providing a reference for the modernization and standardization of Mongolian medicine.

OBJECTIVETo investigate the effect of phosphorylated protein kinase C epsilon (pPKC epsilon) on apoptosis of 32D cells induced by sera from patients with aplastic anemia (AA).

METHODSThe expression of pPKC epsilon and apoptosis in 32D cells were measured by Western blotting and flow cytometry after incubation with sera from healthy individuals (controls, n = 8), patients with severe AA ( SAA, n = 8)and non severe AA (NSAA, n = 6).

RESULTSAfter incubation for 0, 12, 24, 36 and 48 hours in the presence of serum and for another 4 hours in medium deprived of serum, the levels of pPKC epsilon in cells in SAA and NSAA group increased gradually, peaked at 24 hours, and then declined (P < 0.05). Compared with that in control group (0.54 +/- 0.08), pPKC epsilon was overexpressed in both SAA group (0.90 +/- 0.10) and NSAA group (0.64 +/- 0.08) (P < 0.05) after 24 hours incubation with serum and subsequent 4 hours without serum. pPKC epsilon level was higher in SAA group than in NSAA group (P < 0.05). A greater proportion of 32D cells showed apoptosis after 24 hours incubation with sera from SAA patients [(4.05 +/- 1.05)%] and subsequent 4 hours incubation without serum than that in controls [(2.45 +/- 0.51)%, P < 0.05], which was correlated with the same serum-induced expression of pPKC epsilon (r = 0.869, P < 0.05). Although the mean level of pPKC epsilon expression was higher in NSAA group than in control group, no significant difference of apoptosis was found between the two groups [(2.45 +/- 0.51)% vs (3.24 +/- 0.56)%, P > 0.05].

CONCLUSIONSera from both SAA and NSAA patients could upregulate the expression of pPKC epsilon in 32D cells. The SAA sera induce apoptosis in 32D cells significantly, but the latter do not.

Objective To evaluate the application of three-dimensional measurement and computer-aided navigation system in treatment of orbitozygomatic complex fiacture.Methods Pre-and post-operative three-dimensional measurements were taken by Mimics software to locate the zygomatic bones of 15 patients with orbitozygomatic complex ftacture to determine distance of optical foramen to zygomaticotemporal suture (On-Zm)/ zygomaticofrontal suture (On-Or)/zygomaticomaxillary suture (OnTz),horizontal angle of zygomatic arch,horizontal angle of the zygomatic process,and inferior angel of the frontal process of zygomatic bone.Preoperative design and simulation,intraoperative real time navigation and postoperative evaluation were applied using computer assisted navigation system.Results OnTz,On-Or,and On-Zm was (48.6-±4.5)mm,(42.5±2.2)mm,and (47.5±3.2)mmin the unaffected side,but was (50.4 ± 2.2) mm,(37.2 ± 1.0) mm,and (53.4 ± 3.6) mm in the affected side before operation (P ＜ 0.05).Whereas On-Tz,On-Or,and On-Zm improved to (46.4 ± 3.7) mm,(41.2 ± 1.8) mm,and (46.4 ± 2.5) mm in the affected side after operation,similar with the values in the unaffected side (P ＜ 0.05).Horizontal angle of zygomatic arch,horizontal angle of the zygomatic process,and inferior angel of the frontal process of zygomatic bone was (144.7 ±4.1)°,(132.5 ± 2.3)°,and (112.0 ± 3.4)° in the affected side,with significant differences from (150.3 ± 8.0)°,(141.1 ±4.2)°,and (114.9 ±5.1)° in the affected side before operation (P ＜0.05),but they were improved to almost the normal values (144.6 ± 4.1) o,(132.8 ± 2.0) °,and (111.9 ± 3.6) ° after operation.Satisfactory surgical outcomes,such as three dimensional symmetry and recovery of normal mouth-openingand occlusion,had been achieved.Conclusions Three-dimensional measurement is a quantitative study on the spatial displacement of orbitozygomatic complex.Combined with computer-assisted navigation system with preoperative design and simulation,intraoperative real time navigation and postoperative evaluation,three-dimensional measurement attains the overall management of orbitozygomatic complex fracture.

Objective To investigate the changes of quantitative parameters of dynamic enhanced CT in non-small cell lung cancer before and after targeted therapy,and compare them with the traditional evaluation criteria,in order to find the parameters which can be exploited for timely,objective evaluation of the effect of targeted therapy.Methods The study included 21 patients with targeted therapy who had received dynamic enhanced CT before and after treatment.Enhancement time-density curves were obtained based on the CT values of the lesion at individual time points,and the functional indices:peak height (PH),the time to peak height (Tp),the ratio of PH of the mass to aorta (M/A) and perfusion value were calculated.The effects of the treatment on these indices were evaluated and compared with the effect of the treatment on lesion diameter. Results Twenty-one patients had 33 rechecking results. There was a statistically significant agreement between lesion diameter-based treatment evaluation and perfusion-based treatment evaluation ( U =8.761,P ＜ 0.01 ). The perfusion value decreased in patients with disease regression[before treatment:(0.28 ±0.11 ) ml · min-1 · ml-1,after targeted therapy(0.18 ±0.09) ml ·min-1 · ml-1,t =- 3.2722,P =0.0042],but increased in patients with disease progression[before treatment(0.21 ±0.08) ml · min-1 · ml-1,after targeted therapy:(0.34 ±0.11 ) ml · min-1 · ml-1,t =2.6064,P =0.0403].Conclusions On dynamic enhanced CT in non-small cell lung cancer patients after targeted therapy,perfusion value changed in the same trend as the diameter of tumor.The effectiveness of targeted therapy may be evaluated by perfusion value changes.
