The design space of the high shear wet granulation process was established and validated within the framework of quality by design (QbD). The system of microcrystalline cellulose-de-ioned water was used in this study. The median granule size and bulk density of granules were identified as critical quality attributes. Plackeet-Burmann experimental design was used to screen these factors as follows: dry mixing time, the impeller and chopper speed of dry mixing, water amount, water addition time, wet massing time, the impeller and chopper speed of wet massing and drying time. And the optimization was implemented with the central composite experimental design based on screened critical process parameters. The design space of the high shear wet granulation process was established based on the quadratic polynomial regression model. Since the P-values of both models were less than 0.05 and values of lack of fit were more than 0.1, the relationship between critical quality attributes and critical process parameters could be well described by the two models. The reliability of design space, illustrated by overlay plot, was improved with the addition of 95% confidence interval. For those granules whose process parameters were in the design space, the granule size could be controlled within 250 to 355 μm, and the bulk density could be controlled within a range of 0.4 to 0.6 g x cm(-3). The robustness and flexibility of the high shear wet granulation process have been enhanced via the establishment of the design space based on the QbD concept.

Blepharospasm is a focal dystonia of the orbicularis oculi muscles, producing excessive eye closure. The etiology and pathogenesis is still unclear now. lt is usually appearing in adult period and predominant in females. The symptoms are typically triggered by stress, fatigue, intense light or individual factors. At advanced stages patients develop functional blindness. At present the main treatments include: botulinum toxin ( BTX ) , surgical procedures, systemic and ocular drugs and traditional Chinese medicine treatment. BTX administration has been an effective treatment. Surgical procedures have good effect but should be limited to the rare patients that do not respond to botulinum toxin treatment. A great variety of drugs have poor results. Chinese medicine has a certain therapeutic effect. Transcranial magnetic stimulation can improve symptoms. The epidemiology, anatomy, physiology, clinical manifestations, differential diagnosis, pathogenesis and treatment system were reviewed in this paper.

Objective To master the epidemic prevalence and the risk factors of brucellosis in animals and human,and to provide a basis for making prevention strategies and measures to brucellosis in Chongqing Municipality.Methods Qijiang and Wansheng district of Chongqing Munipality were selected as investigation points.Feeding status of goats in feedlots was investigated,and blood samples of goats were collected for laboratory testing.Epidemiological survey in employees on feedlots,family members closely exposed with goats,and other focus groups such as stockbreeding and veterinary was conducted,and blood samples was collected for laboratory testing according to the principle of informed consent.Clinical features of infested persons were investigated.Blood samples were screened by plate agglutination test (RBPT) and tube agglutination test (SAT).Results A total of 582 households in the two districts were investigated.The number of positive households was 40 households.The positive rate of the households was 6.87％.A total of 20 105 goat blood samples were tested.Of them,989 blood samples tested positive.The positive rate was 4.92％.A total of 337 blood samples of the risk population from 22 towns of the two districts were tested.Of them,45 samples were positive,and the positive rate was 13.35％.Eleven people were active patients of brucellosis.The epidemic sites were distributed in 16 towns,which accounted for 73.73％.The difference of the positive rates between the two districts was not significant (x2 =0.37,P ＞ 0.05).The positive rate of brucellosis among male and female was 11.57％ (28/242) and 17.89％ (17/95),respectively.The age of brucellosis infection distributed from 2 years old to 83 years old.One preschool child and 3 students were identified positive.The positive rate of brucellosis among feeder was the highest,which accounted for 31.75％ (40/125).The difference of positive rate of brucellosis among different professions was significant (x2 =63.40,P ＜ 0.05).Conclusions There is not a brucellosis case among animals or people reported in Chongqing non epidemic areas of brucellosis,but there are lots of infection.Surveillance and prevention of brucellosis should be strengthened in Chongqing.

Surface transcutaneous electric nerve stimulation(TENS) was applied to treat the spasiticity resulting from spinal cord injury(SCI) in the acupoints of the subjects with SCI in order to oberve thetranscient and long-term effect of the treatment Fand its mechanism will be discussed in this paper. The results show that: 1 )more significant effect in relieving the spasiticiy was got by stimulating in high frequencyfor 30minutes,while less effect in low frequency(2Hz) ; 2)the effect in high frequency was partially ostracized by naloxone; 3)the effect in high frequency lasted for a long time i 4)compared with lumbar and sacralstimulation,the acupoint stimulation lasted for the longest time. This study also gets a hypothesis that highfrequency TENS in acupoints improves dynorphin in CSF to release and significantly relieve the spasiticityby kappa opioid receptor which decreases the excitment of anterior motor neuron.

OBJECTIVETo investigate gene mutations and the relationship between genotypes and clinical phenotypes in Uygur children with 21-hydroxylase deficiency (21-OHD) in Xinjiang, China.

METHODSA total of 20 Uygur children with 21-OHD who visited the hospital between October 2013 and October 2014 were enrolled. Full-length direct sequencing and multiplex ligation-dependent probe amplification (MLPA) were used to detect the mutations of CYP21A2 gene, which encoded 21-hydroxylase. According to the type of mutation, the patients with 21-OHD were divided into different groups to analyze the consistency between predicted clinical phenotypes and actual clinical phenotypes.

RESULTSA total of 9 mutation types were found in the 20 patients, and 8 of them were identified as pathogenic mutations, i.e., Del, conv, I2g, I172N, Cluster E6, 8-bp del, V281L, and R356W. The other mutation is the new mutation occurring in intron 5 (c.648+37A>G), which had not been reported, and its pathological significance remains unknown. Most clinical phenotypes predicted by mutation types had a higher coincidence rate with actual clinical phenotypes (above 67%), and the clinical phenotypes predicted by P30L and V281L had a lower coincidence rate with actual clinical phenotypes (below 33%).

CONCLUSIONSThe genotype of 21-OHD has a good correlation with phenotype, and the clinical phenotype can be predicted by detecting the patient′s genotype. The new mutation (c.648+37A>G) may be related to the pathogenesis of 21-OHD.
