There should be confusion about diagnosis and treatment for multiple segments cervical myelopathy in some respects. The author reviewed the literature and combined with clinical experience, proposed a new classification for cervical myelopathy according to responsibility segment areas, which dividing into single segment,double segments (continues or jumping type), multi-segment (≥ three segments). The responsible segments determination is the premise of diagnosis and also a key to determine surgical decompression segment. Decompression only according to imaging was not desirable, surgical segment should mainly relies on clinical, imaging, electrophysiological and comprehensive analysis to avoid surgery range expansion. Surgical approach and procedures are still the focus and hotspot of cervical myelopathy treatment, and no treatment standards and corresponding guidelines to consult. The author proposes that surgical approach should advocate the individual, and surgical procedure should follow simple instead of complicate, anterior and posterior combined decompression is not necessary in most cases, and anterior and posterior fixation are not need.

Aim To observe the effect of dopamine (DA) and its antagonist on the electrical activities of pain excitation neurons (PEN) in the caudate nucleus (Cd) of morphine dependent rats. Methods The right sciatic nerve was stimulated by train of electrical impulses as noxious stimuli to morphine dependent rats.The electrical discharges of PEN in Cd were recorded with glass microelectrode to observe influences of intracerebroventricular (icv) injection of DA and droperidol on the electrical activities of PEN. Results DA could decrease excitabilities of PEN in Cd of morphine dependent rats. Conclusion Results suggest that the depression of DA on PEN response in Cd of morphine dependent rats might be blocked by droperidol.

Objective To compare the effect of the tissue adhesive Histoacryl and traditional suturing treatment on the cracked wounds on children's craniofacial skin. Methods About 152 children patients with cracked wounds children's craniofacial skin from March 2015 to June 2015 were divided into two groups according to their parents' will. Group A, with 77 patients, was treated by the tissue adhesive Histoacryl and Group B, with 75 patients, was treated by traditional suturing. The two groups were compare in terms of the treatment time and effect. Result The treatment time of Group A was significantly shorter than that of Group B (P<0.001), while there was no significant difference between the two groups in the level of wound healing (P>0.05). Conclusions Compared to the traditional suturing, the tissue adhesive Histoacryl is advantageous, for its easy operation, short treatment time, prominent efficacy and beautiful appearance. Moreover, it can relieve the pain of children during the treatment.

Objective To investigate the combination effect of tramadol and low dose propofol on emergence agitation in children receiving sevoflurane for adenotonsillectomy procedure. Methods Ninety patients receiving sevoflurane for adenotonsillectomy procedure were randomly divided into control group (administration of 0.1 mL/kg normal saline 30 min before the end of operation), tramadol group (administration of 1 mg/kg tramadol 30 min before the end of operation) and tramadol + propofol group (administration of 1 mg/kg tramadol 30 min before the end of operation and 1 mg/kg propofol at the end of operation). Time of extubation and time stayed in postanesthetic care unit (PACU) after operation were recorded, scores of Pediatric Anesthesia Emergence Delirium ( PAED) Scale, modified Aldrete scores and pain scores were obtained immediately after entrance into PACU, and the prevalences of post-operative nausea and vomiting were observed. Results There was no significant difference in time of extubation, time stayed in PACU and modified Aldrete Scores among groups (P >0.05). There were significant differences in scores of PAED Scale immediately after entrance into PACU, with control group > tramadol group > tramadol + propofol group (P < 0.05). The pain scores of tramadol group and tramadol + propofol group were significantly lower than that of control group (P < 0.05). The prevalence of nausea and vomiting was the highest in tramadol group, and the prevalence in tramadol + propofol group was significantly lower than that in tramadol group ( P < 0.05). Conclusion The combination use of tramadol and low dose propofol can decrease the severity of emergence agitation in children receiving sevoflurane for adenotonsillectomy procedure, and reduce the prevalence of nausea and vomiting.

Vibrio parahaemolyticus has been considered as one of the most important foodborne bacterial pathogens.The loop-mediated isothermal amplification(LAMP) that amplifies DNA with high specificity and rapidity under an isothermal condition was applied for rapid detection of this pathogen for the first time.A set of four primers,two outer and two inner primers,was designed specifically to recognize the thermolabile hemolysin gene(tlh) of V.parahaemolyticus.The LAMP reaction mix was optimized.The most optimal reaction temperature and time of the LAMP assay for the tlh gene were 60℃ and 60min,respectively.Genomic DNAs from 28 bacterial strains including 14 V.parahaemolyticus strains were amplified using LAMP,and no amplicon was observed in other bacterial strains.The detection limit of this LAMP assay was around 90 fg of V.parahaemolyticus genomic DNA and 24 colonies forming units for pure cultures.In addition,this method was applied to detect artificially contaminated food samples,and the detection limit was 89 cfu/g for non-cultured artificially contaminated food samples.These results suggested that detection of V.parahaemolyticus by LAMP is an effective and low-cost procedure with high specificity and sensitivity that requires no specialized equipment.This assay is expected to become a valuable tool for rapid detection and identification of V.parahaemolyticus.

To increase the biotransfomation efficiency from the orotic acid to the uridine 5'-monophosphate(UMP),URA5 gene encoding orotate phosphoribosytransferase was amplified from Saccharomyces cerevisiae BY4742 by PCR,then it was inserted into the expression vector pYX212(contained orotidine monophosphate decarboxylase gene URA3)and the pYX212-URA5 was transformed into Saccharomyces cerevisiae BJX12 by electroporation.The recombinant strain was elementarily used to convert orotic acid to UMP.The results showed that pYX212-URA5/BJX12 could accumulate 7mmol/L UMP from 32mmol/L orotic acid in 26h,significantly higher than both control groups pYX212/BJX12(2.7mmol/L) and BJX12(2.4 mmol/L).

A 56-year-old female patient of Han nationality presented with generalized erythema and vesicles for 6 days,as well as high fever for 2 days.Twenty days prior to hospitalization,the patient received surgical treatment combined with oral methazolamide and glucocorticoids for glaucoma.The patient had a history of allergy to sulfanilamides.On admission,the patient presented with generalized erythema,vesicles and occasional erosions with bilateral eyelid and oral involvement.Nikolsky's sign was positive.Wheezing sound was heard over the right lung.Genetic testing showed that HLA-B5901 allele was positive.The patient was diagnosed with methazolamide-induced toxic epidermal necrolysis (TEN) complicated by pneumonia,and managed with immunoglobulin (25 g/day,5 days),glucocorticoids (the largest dose equivalent to methylprednisolone 160 mg/day),fresh plasma,antibiotics,as well as other supporting and symptomatic treatments.The condition was controlled after 2 weeks,and the patient was cured and discharged from hospital after 25 days.The fact that the patient carried HLA-B5901 allele suggests that HLA-B5901 is strongly correlated with methazolamide-induced TEN or Stevens-Johnson syndrome in Chinese descendants or Han population,besides in Japanese and Korean descendants.

Aim To investigate the periphery analge-sic effect of myricetin on a rat model of inflammatory pain and the mechanism. Methods Rat models of in-flammatory pain were induced by complete Freund ’ s adjuvant ( CFA) injection in left hindlimb plantar cen-ter. The thermal withdrawal latency ( TWL) was meas-ured before and after CFA or myricetin treatment. Elec-trophysiological method was used to identify the effect of myricetin on the action potential frequency and the voltage dependent potassium channel currents in small DRG neurons. Results Rats with CFA injected showed thermal hyperalgesia ( P <0. 05 ) and TWL in-creased significantly after myricetin intraperitoneally in-jected ( P <0. 05 ) . Current clamp recording showed the action potential frequency of small DRG neurons in rats was inhibited by myricetin ( P<0. 01 ) and voltage calmap recording showed the inhibitory effect of myr-icetin was enhanced by calcium depended potassium channel currents ( P<0. 05 ) . Conclusion Myricetin exerts periphery analgesic effect by enhancing calcium depended potassium channel currents and inhibiting excitability of small neurons of dorsal root ganglion.
