Objective To observe the effect of botulinum toxin A (BTX-A) on spasticity of upper extremity with different functional status after stroke.Methods 32 post-stroke patents with upper extremity spasticity were divided into the good function group (n=13) and poor function group (n=19) according to the function of upper extremity. All patients in two groups were treated with injection of domestic BTX-A at the biceps brachii and rehabilitation therapy. The efficacy was assessed with rang of motion, Modified Ashowrth Scale (MAS), Fugl-Meyer Assessment (FMA) and Mot-FIM upper extremity before and 8-week after treatment.Results After treatment, the rang of motion and FMA scores of patients in two groups improved ( P<0.05), but the good function group was superior to the poor function group; the scores of MAS of two groups were not different ( P>0.05); the scores of Mot-FIM upper extremity of the patients in two groups increased ( P<0.05), and there was no significant difference between two groups ( P>0.05).Conclusion The effect of BTX-A injection at the biceps brachii on post-stroke patients with good function of upper extremity is superior to the patients with poor function of upper extremity.

Objective: To observe the clinical efficacy of herbal cake-partitioned moxibustion for dysmenorrhea due to deficiency cold. Methods: A total of 70 patients with dysmenorrhea who met the inclusion criteria were randomized into a mild moxibustion group and a herbal cake-partitioned moxibustion group by the random number table, with 35 cases in each group. Shenque (CV 8), Zhongji (CV 3) and bilateral Zigong (EX-CA 1) were selected for both groups. The treatment continued for 3 menstrual cycles. The visual analog scale (VAS) and COX menstrual symptom scale (CMSS) were scored in both groups before treatment, after treatment and at the end of the 3rd menstrual cycle after treatment. The clinical efficacy was evaluated at the end of the 3rd menstrual cycle after treatment. Results: After treatment, the clinical efficacy of the herbal cake-partitioned moxibustion group had the tendency to be superior to that of the mild moxibustion group, while there was no statistically significant difference in the overall efficacy between the two groups (P>0.05). The VAS and CMSS scores after treatment and at the follow-up were significantly lower than those before treatment in both groups (all P<0.05). At the follow-up, the VAS scores in both groups had no significant intra-group differences from those after treatment (both P>0.05). The CMSS scores in both groups were significantly lower than those after treatment (both P<0.05). The VAS scores at the follow-up of both groups had no statistical differences from those after treatment (both P>0.05). After treatment, the CMSS score in the herbal cake-partitioned moxibustion group was significantly lower than that in the mild moxibustion group (P<0.05). At the follow-up, there were no statistical differences in the CMSS score between the two groups (P>0.05). Conclusion: The herbal cake-partitioned moxibustion has the same therapeutic efficacy for dysmenorrhea as the mild moxibustion; the two moxibustion methods can significantly improve the concomitant symptoms of dysmenorrhea, and the herbal cake-partitioned moxibustion is little better.

Objective To compare the clinic features of neuromyelitis optica (NMO) and multiple sclerosis(MS).To compare the positive rate of NMO-IgG in NMO,MS and other related diseases,and determine whether it can be considered as a biomarker for differential diagnosis.Methods Detected serum NMO-IgG in 34 NMO patients,22 MS patients,24 high risk syndrome,5 clinical isolated syndrome,and 35 patients with other neumlogical diseases.Compared the clinic features(onset age,severity,prognosis,MRI lesions,autoimmune antibodies,CSF)of 34 NMO patients and 22 MS patients.Results The onset age of NMO is older than that of MS.It is more severe and with worse prognosis than MS.Longitudinal spinal cord lesions are easily found in NMO.NMO-IgG positive rate in NMO and high risk syndrome patients are 58.8% (20/34)and 45.8%(11/24)respectively,which are higher than that in MS(1/22),clinical isolated syndrome(1/5)and other neurological diseases(1/35;x2=37.2,P<0.01).The positive rate may have a relationship with the length of spinal cord lesions.Condusions MS and NMO are probably different diseases.NMO-IgG positive rate in NMO is significandy higher than that in MS,it can be considered as a biomarker for differential diagnosis.

Objective To investigate the effects of subretinal fluid drainage combined with intravitreal anti-vascular endothelial growth factor (VEGF) drugs in the treatment of severe exudative retinal detachment Coats disease.Methods Thirteen patients (13 eyes) with 3B Coats' disease diagnosed at the Eye Center of Tongren Hospital were included in the study.The participants were aged from 1 year to 11 years with a mean age of (4.15 ± 2.99) years.The visual acuity was no light perception in 1 case,from light perception to counting finger in 7 cases,from 0.01 to 0.1 in 2 cases,and could not be measured due to young in 3 cases.Patients underwent retinal fluid drainage combined with intravitreal ranibizumab (IVR,0.5 mg,0.05 mL) at the pars plana of ciliary body,and with retinal laser photocoagulation or cryotherapy according to the retinal peripheral vascular activity.During the follow-up,the visual acuity,intraocular pressure,slit lamp,indirect ophthalmoscope and color ophthalmoscope were examined and observed.The abnormal blood vessel change,absorption of subretinal fluid,retinal reattachment and complication were observed.Results Two subretinal fluid drainage were performed in 3 cases,one subretinal fluid drainage in 10 cases.Six cases were combined with two intravitreal injections,4 cases with three intravitral injection,3 cases with intravitreal injection for more than three times.Five cases were treated with simple photocoagulation,3 cases with simple retinal cryotherapy,and 5 cases with laser combined with cryotherapy.In 13 patients,the visual acuity was improved in 2 cases,unchanged in 8 cases,and could not be measured due to young in 3 cases.Eight cases had complete retinal reattachment.No significant postoperative complications occurred during follow-up,such as endophthalmitis,retinal hole and vitreous hemorrhage.Conclusion Subretinal fluid drainage combined with intravitreal injection is an effective method for severe 3B stage Coats disease.

Hide melting presents itself as one of the most critical processes in the production of donkey-hide gelatin. Here a NIR-based method was established for the rapid analysis of in-process hide melting solutions as well as for end-point determination of this process. Near infrared (NIR) spectra of hide melting solutions were collected in transflective mode. With the contents of total nitrogen determined by the Kjeldahl method as reference values, partial least squares regression (PLSR) was employed to build calibration models between NIR spectra and total nitrogen. Model parameters including wavelength range and PLS factors were optimized to achieve best model performance. Based on the contents of total nitrogen predicted by calibration model, end point of hide melting was determined. The constructed PLS model gave a high correlation coefficient (R2) of 0.991 3 and a root mean square error of prediction (RMSEP) of 0.807 g x L(-1). With the predicted total nitrogen and predefined limit, decisions concerning the proper times of melting were made. This research demonstrated that NIR transflectance spectroscopy could be used to expeditiously determine the contents of total nitrogen which was subsequently chosen as the indictor for determining the end-point of hide melting. The proposed procedure may help avoid unnecessary raw material or energy consumption.

Racemic (±)-F18 (10-chloromethyl-11-demethyl-12-oxo-calanolide A), an analog of nature product (+)-calanolide A, is a new anti-HIV-1 nonnucleoside reverse transcript inhibitor (NNRTI). A successful enantioseparation of (±)-F18 offering (R)-F18 and (S)-F18 was achieved by a chiral stationary phase prepared HPLC. Their absolute configurations were determined by measurement of their electronic circular dichroisms combined with modem quantum-chemical calculations. Further investigation revealed that (R)-F18 and (S)-F18 shared a similar anti-HIV activities, however, (R)-F18 was more potent than (S)-F18 against wild-type virus, K101E mutation and P225H mutation pseudoviruses.
