Primary focal hyperhidrosis is a disorder of excessive sweating beyond physiological thermoregulation.It can affect the armpits,palms,soles,face,and so on.The etiology and pathogenesis is unclear.The latest study in pathogenesis is the secretory clear cell of the eccrine sweat gland.Apart from the use of antiperspirants and anticholinesterase drugs,other treatments include the injection of botulinum toxin A and surgery.

Animal models using for research the cancer matestasis should be entirely similar to the clinical pathological process in patients.Currently,two kinds of animal models with genetic engineering and human tumor xenografts are available in laboratory,which provide a possible research tool to investigate the mechanism of tumor metastasis and explore the experimental treatment.In these models,the techniques including how to select the cell lines and using real-time imaging detection are very important factors.

In order to make a rational and effective cure measure for lung cancer,people need to establish suitable animal model.Spontaneous or induced model needs long time to form tumor and the rate is not steady.Xenograft mouse model is widely used in laboratories because of its steady tumor formation rate and less time in oncogenesis.Engineered mouse model which is based on genetic technology not only helps us to understand pathological process of lung cancer,but also can provide an ideal preclinical model of targeted therapy experiment,and it will be the important development direction of lung cancer animal model.

Registration of serial images plays an increasingly important role in medicine. A novel registration method used for serial images matching is proposed, which is based on the joint histogram. After thresholding the two images to be registered, the joint histogram is divided into four separate regions. Then the criterion function is defined as bin counting in a specific region of the joint histogram, which simplifies the computation of the criteria function greatly and speeds up the alignment process significantly. We choose the Powell optimization algorithm to calculate the registration parameters. The comparison of the results from both mutual information and our method shows that the new method based on segmentation and counting is a fast, simple, efficient and accurate registration method.

An examination was conducted with holographic stereopsis test instrument on the stereoscopic vision function of 341 military personnel in different services. 94.7 percent of the total examined enjoyed normal stereopsis acuity. The pilots obtained the far most satisfactory result. One hundred percent of them were up to normal standard in terms of both far and near visions and stereopsis acuity. Meanwhile, 94.6 percent of the vehicle drivers examined also had normal stereopsis acuity. This percentage was higher compared with 83.78 percent of the civilian personnel of the same occupation. The above results indicate that the stereopsis function of personnel in military services is in good condition, and such examination is very effective and necessary as part of the physical examinations in conscription to assure the standard of the service men.

Objective To optimize the prescription ofBaichanting Tablets by the central composite design-response surface methodology.Methods The doses of MCC, cCMC-Na, SiO2, and magnesium stearate were set as investigation factors; disintegration time and moisture rate were set as indexes. Linear equation quadratic polynomial described mathematic relationship of disintegration time and moisture rate with other four influence factors. Response surface was described according to the optimal mathematic models; the optimal prescription was chosen; predictive analysis was conducted.ResultsThe relationship of disintegration time and moisture rate with other four influence factors could not be described by linear equation. When quadratic polynomial matching was used, correlation coefficients were 0.837 9 and 0.923 1, with relatively high reliability. Optimal prescription contained 30.6%MCC, 10%cCMC-Na, 0.30%SiO2, and 0.10% magnesium stearate. The theoretical value and predicted value deviations of the disintegration time limit and moisture absorption rate were within 5%.Conclusion The predictability of the established model is good. Application of central composite design-response surface methodology can precisely optimize the prescription ofBaichanting Tablets.

ObjectiveTo study the neuron protection mechanism of Uncariae Ramulus Cum Uncis extract for the MPTP-induced PD mice.MethodsC57BL/6 mice were randomly divided into control group, model group, Uncariae Ramulus Cum Uncis extract group and madopar group, and injected with MPTP in abdominal cavity. Behavior test was used to detect grabbing capacity and body movement coordination capacity: three biochemical indexes (SOD, MDA, GSH-Px) were detected by biochemical process and the activity of two immune enzyme-linked indexes (IL-1β, IL-6) were detected by enzymelinked immunosorbent assay.ResultsCompared with the control group, the autonomic activity numbers of mice increased and climbing pole time decreased in the model group (P<0.05), enzymatic activity of SOD and GSH-Px decreased significantly and the contents of MDA, IL-1β and IL-6 increased obviously (P<0.01). Compared with model group, the autonomic activity numbers of mice increased and climbing pole time decreased in the Uncariae Ramulus Cum Uncis extract group and madopar group (P<0.05). Enzymatic activity of SOD and GSH-Px increased and the contents of MDA and IL-1β and IL-6 decreased (P<0.05,P<0.01).ConclusionUncariae Ramulus Cum Uncis extract can reduce neuronic apoptosis PD mice, whose therapeutic action may be realized through eliminating oxygen free radicals, improving oxidation resistance and reducing inflammatory reactions.

Objective To investigate the value of otolith-repositioning maneuver combined with medical treatment on benign paroxysmal positional vertigo in the elderly patients.Methods 176 elderly people who suffered from benign paroxysmal positional vertigo were randomly divided into observation group and control group (n=88,each).All patients were treated with basal medicine treatment and compulsive position for 21 days,and patients in the observation group were treated with otolith repositioning maneuver added on the basis.The clinical efficacy and adverse reactions were observed and compared between the two groups after treatment.Results The curative rate and effective rate were higher in observation group than in control group at 2,3 weeks after treatment [50.0％ (44/88) vs.11.4％ (10/88),70.5％ (62/88) vs.47.7％ (42/88),77.3％ (68/88) vs.29.5％ (26/88),93.2％ (82/88) vs.86.4％ (76/88),x2 =37.32,73.32,37.32,53.43,respectively,all P＜0.05].Dizziness combined with nausea and vomiting,and walking instability were both found in the two groups,which had no statistical difference (x2 =3.25,P＞0.05).Patients in observation group developed arrhythmia and Tumarkin otolith crisis after treatment.The transfer rate of surgery was lower in observation group than in control group (x2 =45.43,P＜0.01).Conclusions Otolith-repositioning maneuver combined with medical treatment have good clinical effect and safety on benign paroxysmal positional vertigo in the elderly.

Objective To evaluate the value of furosemide in magnetic resonance urography(MRU) with low field magnet.Methods The routine MRU and MRU after administration of intravein of furosemide were performed with heavily T_2 weighted fast spin echo pulse sequence in 32 cases with urethral diseases.Then three-dimensional(3D) reconstruction for post procedure processing with a maximum-intensity projection(MIP)algorithm was done.Results On routine MRU,there were no image of collecting systems of kidney in 5 cases,and poor images of parenchyma and collecting systems of kidney in 18 cases after using furosemide before MRU,MRU provided high resolution images of parenchyma and collecting systems of kidney in all cases,and images were much clear,the localized diagnosis was accurate.Conclusion MRU using furosemide before scanning can display the parenchyma and collecting systems of kidney distinctively,so furosemide can be regarded as a routine method used before MRU with low field magnet.
