BACKGROUND:Studies have shown that craniocerebral injury can promote the repair of sciatic nerve injury in rats, but its precise mechanism remains unclear.
OBJECTIVE:To further explore the action mechanism of craniocerebral injury on the repair of sciatic nerve injury using morphology and histology.
METHODS:Sixty specific-pathogen-free healthy male Sprague-Dawley rats were randomly divided into two groups. Rats with craniocerebral injury and sciatic nerve injury were considered as the experimental group. Rats with simple sciatic nerve injury were considered as the control group. Classical Feeney method was used in models of craniocerebral injury and SunderlandV sciatic nerve injury. At 8 and 12 weeks after modeling, sciatic nerve index was detected. Masson staining and NF200 immunofluorescence staining were used to observethe nerve regeneration atthe anstomotic site. Transmission electron microscope was used to observe the number of regenerative axons.
RESULTS AND CONCLUSION:At 8 and 12 weeks after modeling, compared with the control group, gait and sciatic nerve index recovered better in the experimental group. In the experimental group, Masson staining showed fewer nerve membrane colagen fibers, and the axon arranged neatly.NF200 immunohistochemistry showed that in the experimental group, the density of regenerated nerves was high, and nerveswere regularly distributed. Transmission electron microscopy showed that in the experimental group, regenerative axons were regularly arranged, colagen scar was less, and myelin layer arranged regularly. Results suggested that the craniocerebral injury in rats may promote the repair of peripheral nerve injury by reducing scar colagen in nerve endings.

BACKGROUND:Recovery of motor and sensory function from peripheral nerve injury is relatively slow and incomplete. It is a difficult problem for orthopedic surgeons that mainly leads to the decline in the quality of life in patients.
OBJECTIVE: To conclude the methods and corresponding outcomes in peripheral nerve regeneration by analyzing the new treatment means for peripheral nerve injury.
METHODS:PubMed, Wanfang, CNKI databases were retrieved for relevant articles using key words of “nerve injury, regeneration”, and then retrieval data were sorted and analyzed.
RESULTS AND CONCLUSION:In recent years, in-depth studies on peripheral nerve repair have been made in the folowing aspects: surgical mode, drug, cytokine, gene transfer and biomaterials as wel as traditional Chinese medicine. If the detect size is four times longer than the diameter of nerves, the nerve regeneration chamber can achieve good outcomes. The methods of restoring nerve continuity folowing nerve injury are developed from surgical anastomosis to photochemohistological method, thermal laser welding, plastic repair and other emerging technologies. Studies have found that plasminogen activator, nerve growth factor, neurotrophic factor, recombinant erythropoietin, human tissue kalikrein, B vitamins and their derivatives, herbal preparations, immunosuppressive agents al can promote nerve regeneration.

Objective To investigate the radiological features of granulomatous mastitis (GM) in dynamic contrast enhanced MRI (DCE-MRI) and DWI and to differentiate it from the breast cancer in diagnose.Methods Forty five cases of GM and 64 cases of breast cancer confirmed by surgical histopathology or biopsy were retrospectively analyzed in the study.All of the patients were examined preoperatively by DCE-MRI and DWI.Including lesion type,location,enhancement pattern,nipple retraction,supplying arteries,skin thickening and axillary adenopathy in the two groups were evaluated and analyzed by using x2 test.One-way ANOVA was employed to compare the ADC values between the abscess area of GM and non-abscess area,and the difference among the breast cancer lesion area.Dynamic enhancement MR pharmacokinetic parameters were used to measure including early-phase enhancement rate (EER),peak enhancement ratio(Emax),and time to peak ehhancement(Tmax).The statistical differences of EER,Emax and Tmax between the two groups were calculated by using Wilcoxon test.Results In 45 cases of GM,DCE MR images showed nonmass-like lesions (43 patients) and mass-like lesions (2 patients); the nipple involved(16 patients) and segment involved (29 patients);rim-like with heterogeneous enhancement (40 patients) and heterogeneous enhancement (5 patients); nipple retraction (24 patients) supplying arteries dilatation (42 patients),skin thickening (29 patients),and axillary adenopathy (17 patients).Corresponding to the radiological features above,in the 64 breast cancer cases,it showed 54,10,5,59,30,34,16,51,12 and 20,respectively.There were statistical significance between GM and breast cancer in lesion type,location,enhancement pattern,and nipple retraction (x2=67.574,13.075,20.297,20.398 and 23.510,respectively,all P＜0.01).But no differences were existed between 2 groups in supplying arteries and axillary adenopathy(x2=3.928 and 0.502,P＞0.05).EER,Emax and Tmaxin GM were 146.58％,191.13％,195.00 s in GM and 118.13％,159.43％,183.33 s in breast cancer,respectively.Significant statistic differences between GM and breast cancer were found in EER and Emax(Z values were-2.271 and-2.948,P＜0.01).But it did not show significant difference in Tmax (Z =-0.548,P＞0.05).The ADC values of GM on abscess area,non-abscess area,and breast cancer lesion area were (8.0±2.6) × 10-3,(11.3± 1.7) × 10-3 and (8.2± 1.1) × 10-3mm2/s,respectively.There were significant differences in the groups (F=52.167,P＜0.01).Conclusions The characteristic of radiological findings can be found in GM by using advanced MR imaging techniques.DCE-MRI combined with DWI is useful in the differential diagnosis between GM and breast cancer.

OBJECTIVETo explore the effect and mechanism of acupoint sticking of Chuanfuling (CFL) in dog-days (the hottest periods of the year) in preventing and treating children asthma in remission stage.

METHODSNinety patients were divided into three groups, 30 in each. Patients in the CFL group were treated with CFL sticking, in the Western medicine (WM) group treated with Pulmicort inhalation, and in the control group was untreated. The clinical effect and indexes of humoral immunity (IgE, IgA, IgG) and cellular immunity (Eos, IL-4, IFN-gamma) before and after treatment were observed.

RESULTSAfter treatment in the CFL group all the immune parameters were significantly improved (P<0.05 or P<0.01), all were better than those in the control group (P<0.05 or P<0.01), and the effect on IgA and IgG was better than that in the WM group. In the WM group after treatment, improvement was shown on the IgE and cellular immune parameters with signifian difference (P<0.05 or P<0.01), better than those in the control group (P<0.05 or P<0.01). Besides, significant difference was shown in comparing IL-4 level between the WM group and the CFL group (P<0.05).

CONCLUSIONCFL sticking in dog-days could significantly improve the immune function in children with asthma to alleviate and control the attack.

Objective To investigate the intralaboratury and interlabomtory variations of measurements for ALT and AST among four domestic reference laboratories. Methods The International Federation of Clinical Chemistry and Laboratory Medicine (IFCC) reference procedures and IFCC procedures without pyridoxal 5-phosphate (PLP) were performed in the reference laboratories. Intralaboratory and interlaboratory CVs were compared with those in 2006 and 2007 IFCC External Quality Assessment Scheme for Reference Laboratories (RELA). Meanwhile, deviations of results for ALT, AST and AST/ALT between two methods were calculated. Results Interlaboratory CVs were generally higher than intralaboratory CVs. Interlaboratory CVs among the 41 laboratories were lower than these in RELA. Results of ALT and AST using method with PLP were higher than those using method without PLP. Difference of AST/ALT ratio between the two methods was significant. Conclusions For reference measurement of the 2 enzymes, interlaboratory CVs of < 3.5 are achievable on frozen serum materials. Measurements on lyophilized materials may have higher CVs. Further studies are needed for the investigation of the differences between results obtained in the absence and presence of PLP.
