A modified rapid microprocedure for the determination of VE in serum, was described. VE reduced Fe3+ to Fe2+ and then the Fe2+ combined with bathophenanthroline to form a pink complex -which could be determined spect-rophotometrically. As little as 0.3ml (or 0.2ml) of serum or plasma sample was sufficient for determination. The reproducibility of this method was good. The CV was 4.1% (n=15). The recoveries of added VE (0.8, 0.2 and 1.6 mg/dl) were 86.3-102.5%. The mean value and SD of 99 normal adults were 1.15+ 0.31mg/dl. This spectrophotometric method was simple and could be used in common, laboratories. Some affecting frctors were discussed.

Objective To determine the median effective dosage of 0.5% ropivacaine for ultrasoundguided lateral popliteal sciatic nerve block. Methods Twenty-three ASA Ⅰ or Ⅱ patients of both sexes, aged 19-20 yr weighing 52-90 kg received lateral popliteal nerve block guided with ultrasound for foot and ankle surgery.The volume of 0.5% ropivacaine injected was determined by the response of the previous patient using an up-anddown technique. The initial volume was 18 ml. Each time the volume increased/decreased by 2 ml.Successful nerve block was defined as complete loss of pinprick sensation in both tibial and common peroneal nerve distribution with concomitant inability to perform plantar or dorsal flexion of the foot 30 min after injection. Results The median effective dosage of 0.5% ropivacaine resulting in complete block of the sciatic nerve in 50% patients was 13 ml (95% confidence interval 11.3-14.9 ml).Conclusion The median effective dosage of 0.5% ropivacaine for ultrasound-guided lateral popliteal sciatic nerve is 13.0 ml.

Objective To investigate the effects of electroacupuncture at Sanyinjiao (SP6) and Yinlingquan (SP9) on muscle repair in the gastrocnemius muscle damaged rats and its possible mechanism. Methods 30 male Sprague-Dawley rats were randomly divided into blank group (n=10), model group (n=10) and electroacupuncture group (n=10). The latter 2 groups were modeled with gastrocnemius muscle crush injury. The electroacupuncture group received electroacupuncture at Sanyinjiao and Yinlingquan for 14 days. Their gastrocnemius was observed with HE staining, and the expressions of basic fibroblast growth factor (bFGF) and insulin-like growth factor-1 (IGF-1) in gastroc-nemius tissues and the serum were determined with immunochemical assay and enzyme-linked immunosorbent assay (ELISA). Results Compared with the model group, there was less damage in the electroacupuncture group, with more expression of bFGF and IGF-1 in tis-sues (P<0.01) and serum (P<0.05). Conclusion Electroacupuncture can promote muscle repair after gastrocnemius muscle damage in rats, which may be related to the increase of the bFGF and IGF-1 expression in gastrocnemius tissue and serum.

OBJECTIVE:To evaluate the effect and safety of conservative treatment for treating cervical spondylotic radiculopathy by cochrane evaluation systems.DATA SOURCE:CBM(from January 1978 to October 2008),CNKI(from January 1978 to October 2008)and VIP(from January 1989 to October 2008)databases were retrieved by computer and partial documents were searched by hands.DATA SELECTION:Randomized controlled trial was adopted in course of acupuncture and moxibustion treatment for cervicel spondylotic radiculopathy and its quailty was assessed.Dafa source was randomized and semi-randomized controlled.Some evaluations such as random method-selection bias,allocation concealment-selection bias,blind method-performance bias and measurement bias,exclusion.lose to follow-up,withdraw-attrition bias were chosen.MAIN OUTCOME MEASURES:①Abdominal acupuncture needles were superior to the conventional method's efficiency.②Electro-acupuncture plus cupping with barbed floc were superior to the conventional method's efficiency.③Abdominal acupuncture were superior to traction's efficiency.④Cervical traction,electro-acupuncture combined with point injection and massage were superior to traction's efficiency.⑤Traction,electro-acupuncture,massage,TDP-guided were superior to traction,physiotherapy,TDP combined with exercise therepy's efficiency.⑥Vinegar iontophoresis and electro-acupuncture were superior to simple electro-acupuncture's efficiency.⑦Long's approach acupuncture was superior to simple acupuncture's efficiency.⑧Adverse reaction.RESULTS:A total of 1416 subjects were selected from 7 randomized controlled trials.All the studies have selection bias,measurement bias,loss of the high probability of bias,the quality and grade of"C"grade.And only one study proved that the efficiency of the experimental group was better than that of the control group.Study 1 showed that there was insufficient evidence suggested that acupuncture treatment of abdominal cervical spondylotic radiculopathy was efficient than conventional acupuncture.Study 2 showed that there was insufficient evidence suggested that electro-acupuncture plus cupping therapy with barbed floc was efficient than conventional acupuncture to cure cervical spondylotic radiculopathy.Study 3 showed that there was insufficient evidence suggested that acupuncture treatment of abdominal cervical spondylotic rediculopathy was efficient than traction.Study 4 showed that the cervical traction,electro-acupuncture combined with acupoint-injection treatment of cervical spondylotic radiculopathy was efficient than traction combined massage therapy.Study 5 showed that there was insufficient evidence suggested that traction,electro-acupuncture,massage,TDP-guided therapy was efficient than traction,physical therapy,TDP combined with exercise therapy.Study 6 showed that there was insufficient evidence suggested thatelectro-acupuncture combined with vinegar iontophoresis treatment of cervical spondylotic radiculopathy was better than the simple electro-acupuncture therapy.Study 7 showed that there was insufficient evidence suggested that the acupuncture therapy using Long's approach was better than simple acupuncture.No adveme reactions appeared to terminate the test in 7 studies.CONCLUSlON:The above seven studies mainly present with low quality,absence of a unified curative method,small samples,difference of follow-up time,iudgment standard and measurement standard.So more samples,multicenter and more regular randomized controlled trial should be performed.

Objective To investigate the risk factors associated with cranial nerve impairment in patients with tuberculous meningitis.Methods A total of 121 patients with tuberculous meningitis who were admitted to Huashan Hospital from 2000 to 2011 were reviewed retrospectively.Demographic data (gender,age),course of disease,initial results of cerebral spinal fluid (CSF) tests,occurrence of cranial nerve impairment and prognosis of these patients were collected.All the patients were followed up for at least 3 months,and for those with cranial nerve impairment,the minimum follow-up period was 1 year in order to judge the recovery of cranial nerve impairment.Multivariate analysis was performed to study the associated risk factors.Results Out of 121 patients,22 (18.2 ％)developed cranial nerve impairment.Nerves involved were abducens nerve,oculomotor nerve,optic nerve and auditory nerve,and impairment of single nerve occurred in 9 (40.9 ％),8 (36.4 ％),7(31.8％) and 1(4.5％) patient,respectively.Three cases had more than one group of cranial nerves involved,accounting for 13.6％ of the 22 patients with cranial nerve impairment.The incidence of conscious disturbance was significantly higher in patients with cranial nerve impairment than those without impairment (77 ％ vs 45 ％,P=0.020).Delay in diagnosis (OR =1.017,95 ％ CI:1.001-1.033,P=0.040) and occurrence of conscious disturbance (OR =3.242,95 ％ CI:1.142-9.205,P=0.027) were independent predictive factors of cranial nerve injury.During one-year follow-up,90.9％ of patients were fully recovered from cranial nerve impairment,with a median duration of 1 month (range 0.5-6.0 months).Conclusions Cranial nerve impairment is a common complication in patients with tuberculous meningitis.Delay in diagnosis and occurrence of conscious disturbance were independent predictive factors.Most cranial nerve impairment were reversible,and timely diagnosis and treatment are important ways to reduce complications.

This article introduced the mechanism and methods of functional exercise.

OBJECTIVE To mine adverse drug event （ADE） signals related to baloxavir marboxil， and to provide reference for clinically safe drug use. METHODS The ADE signals related to baloxavir marboxil from January 1， 2018 to May 31， 2022 in the US FDA adverse event reporting system （FAERS） were mined using the proportional reporting odds ratio （PRR） method. ADE with report number≥3， PRR≥2 and χ2≥4 was defined as a positive signal， and PRR method was used to analyze the ADE signal. RESULTS A total of 1 424 ADE reports with baloxavir marboxil as the main suspected drug were collected， involving 460 ADE signals. The femininity and patient under 18 years old were reported more， the country with the highest number of reports was the United States， and the main indication of drug reported was influenza. A total of 37 ADE positive signals were obtained after PRR calculation and screening exclusion， the first three ADE signals in the list of the reported number were diarrhea， vomiting and immediate hypersensitivity， and the first three ADE signals in the list of PRR value were febrile delirium， ischaemic colitis and hemorrhagic cystitis. Compared with the instructions of baloxavir marboxil， 18 ADE signals had not yet been included， such as abnormal liver function， hematuria， hemorrhagic cystitis， etc. Five new SOCs were involved， such as kidney and urinary system diseases， hepatobiliary system diseases， investigations， nervous system disorders and musculoskeletal and connective tissue disorders. CONCLUSIONS When clinical application of baloxavir marboxil， in addition to the adverse drug reactions mentioned in the drug instructions， attention should be paid to abnormal liver function， hematuria， hemorrhagic cystitis， etc， so as to guarantee the safety of drug use.

Objective To observe the effects of electro-acupuncture (EA) at “Weizhong” (BL40) on expressions of Fas and FasL in rat models with lumbar disc degeneration; To discuss its mechanism of action.MethodsThirty SD rats were randomly divided into sham-operationgroup, model group and EA group, with 10 rats in each group. The sham-operation group was treated with sham operation to incide local skin; the model and EA groups established rat model of lumbar disc degeneration by puncturing the annulus fibrosus. Four weeks after modeling, rats in the sham-operation and model groups received fixed treatment under identical condition, and rats in the EA group were treated with EA at “Weizhong” (BL40) in 20 minutes, once a day, for 4 weeks. After treatment, Western blot and RT-PCR technology were used to test the protein and mRNA expression levels of Fas and FasL.ResultsThe expressions of Fas and FasL in the model group were higher than those in the sham-operation group (P<0.05); protein and mRNA expression levels of Fas and FasL in the EA group were lower than those in the model group (P<0.05). ConclusionEA at “Weizhong” (BL40) can reduce the expressions of Fas and FasL to inhibit the development of lumbar disc degeneration.
