Conclusion Needle-knife therapy plus balance-acupuncture therapy was obvious better than exclusive needle-knife therapy in treating LIDT in terms of recovery rate and the course of treatment.

Objective:To evaluate the effectiveness of individual operative design for unilateral cleft lip repair.Methods:Individual operation design was applied for the repair of unilateral cleft lip in 40 cases.The operations were conducted according the designs and the secondary nasal deformities were corrected at the same time.One week after operation,dermal sutures were removed,the effects were evaluated by 3 professional doctors.7 labial morphometric lines were measured.The ratio of the line length on healthy side to the correspondence on the cleft side(RLL)were calculated for objective evaluation.Results:First intention was found in all cases,the labial bow of both sides was symmetried after operation.In dynamic state and static state,the effects of the operations were satisfactory.RLL of 0.91-1.10 of the 7 lines was observed in 67.5%-95.0% of the patients.Conclusion:The individual operation design is feasible for unilateral cleft lip repair.

Objective:To explore the therapeutic efficacy of a new access to internal rigid fixation for mandibular condylar fracture. Methods: 7 patients with 9 unilateral mandibular condylar fractures were treated with preauricular beeline incisions. The two trunks of facial nerve were dissected and separated along the surface of the superficial temporal veins. Mandibular ramus periosteum was dissected. The fracture segments were reduced and fixed under sufficient exposure. Results: This operation access provided a sufficient exposure and was convenient for reduction and fixation. All the patients recovered effectively.Conclusion: This surgical approach is one of the feasible methods for reduction and fixation of mandibular condylar fracture.

Objective To investigate the changes and clinical implications of VE-eadherin during the courseof progressive cerebral infarction.Method One hundred sixty-seven patients with acute cerebral infarction of Rong Jun General Hospital of Shandong Province and the Central People' s Hospital of Tengzhou were diagnosed in our hospital from May 2006 to July 2007,were diagnosed according to the ill%gnome criteria set by the 4th national cerebrovascular disease conference in 1995.Of them there were 102 ases with progressive cerebral infarction patients and 65 cases with non-progressive cerebral infaction.The progressive cerebral infarction patients were divided into 3 groups according to Pullicino's expressions:the big infarction focus(32 patients) ,the medium-sized infarction focus(34 patients) and the small infarction focus(36 patients) .The neurological deficits were divided into 3 groups according to the crrteria set by the 4th national cerebrovascular disease conference in 1995:light-defictits(38 patients),the moderate dificits (32 patients) and sever ditlcits (32 patients).The 65 non-progressive irffarction patients were stable without headache,vertigo and tinnitus.Arother 60 healthy subjects were entered as control group.Blood samples of all the patients' were collected at 0 h,24 h,3 d,7 d,14 d,24 d and the serum VE-eadherin by ELISA method was asaayed.All the data were analyzed by SPSS 10.0 software and One-way ANOVA was applied to intergroup comparisons for mote than two groups.Results The VF-cadherin level of patieras with progressive infarction increased in acute stage,reached the peak 3 days after onset,declined remarkably 7 days later and got nearly normalized within 21 days.The results were significantly different from those of non-progressive and controlgroup(P＜0.01).The VE-cadherin concentration was higher in patients with bigger size infarction and more sever symptoms.Conclusions The VE-cadherin level is related to the infarction size,course and the severity,and higher in the progressive group.VE-cadherin could be used for predicting prognostic of cerebral infarction and clinically valuable for treating ischemie cerebrovascular disease.

Magnetic manipulation of particles/cells in microfluidic chips is a promising research field.This paper stated the operation mechanism and the main means of manipulation, including separation, concentration, capture, arrangement and assembly.Especially, the concept of particles/cells separation was emphasized with different criteria, like sizes, shapes, and magnetic properties.In addition, the effects of the channel geometry, the intensity and distribution of the magnetic field, and the types of magnetic liquid (paramagnetic salt solutions and ferrofluids) on the performance of the magnetic manipulation were also compared.The prospective to the prospect of magnetic manipulation about particles/cells in microfluidic chip was also depicted.

Objective To observe the changes and the mechanism of bcl-6 expression in K562 cells inducing differentiation along different Myelocyte-lineage cells,and to investigate the relationship between expression of bcl-6 and directional differentiation of K562 cells.Methods Models of K562 cells inducing differentiation along megakaryocyte-lineage,erythrocyte-lineage and macrophagocyte- lineage were established with inducers TPA(tetradecanoylphorbol 13-acetate),Hu(hydrozyurea)and HMBA(hexamethylene bisacet- amide)respectively,Western blot assay was applied to detect the expression of bcl-6 in K562 cells before and after the induction.Mean- while,PCR,cloning and direct DNA sequencing were used to identify mutations in the 5'regulatory region of bcl-6 in K.562 cells induced with TPA.Results Up-regulation of bcl-6 expression was found only in K562 cells inducing differentiation along megakaryocyte-line- age,and mutation of noncoding regulatory region of bcl-6 gene was not found.Conclusions bcl - 6 may be the key gene to regulate K.562 cells directional differentiation along different myelocyte-lineage ceils,the up-regulation of bcl-6 expression could play an important role in K562 cells inducing differentiation to megakaryocydte-lineage,and the change of bcl-6 expression might be not related with the mutation of the gene's 5'regulatory region.

Specimens of 50 adult brain with meninges were examined under magnificationof 5?.The number of the superior cerebral veins(SCV)varies considerably on bothsides.Cases with 7 branches on one side are most commonly seen. SCV perforate the arachnoid either at the superior border of the cerebral hemi-sphere or far beyond it.More branches perforate the arachnoid beyond the superiorborder of the cerebral hemisphere.The length of SCV between the superior borderof the cerebral hemisphere and the point where the veins perforate the arachnoid ismeasured and in average,the length of the frontal veins and veins of central gyriis longer than that of the parieto-occipital veins.The outer caliber of the frontopolar veins and occipital veins is the smallest andthat of the combined trunk veins is the largest.Bridge veins usually occur in the branches of SCV except the left central vein.The incidence of the bridge vein in the left and right frontopolar veins is thehighest(50～60%).There is an adherent segment occurring in all branches of SCV.The incidenceof the adherent segment in different branches is almost over 50%.Therefore it maybe considered that the presence of the adherent segment in SCV is a normal pheno-menon.The frontal veins and the veins of the central gyri usually adhere to thedura,and the parieto-occipital veins to the lateral wall of the superior sagittal sinusand the cerebral falx.Very few perforated segments can be seen in frontal veins,yet the percentageof its presence in the both sides of the veins of central gyri and parieto-occipitalveins are 9% and 11.22% respectively.Any vein with a perforated segment per-forates the lateral wall of the superior sagittal sinus predominantly.The application of the bridging vein,or adherent segment and perforated seg-ment of the SCV in neurosurgery has been discussed.
