[Objective]To study the safety,clinical effect and therapeutic characteristics of distraction apparatus for correcting flexion contracture deformities of the knee joint by evaluating the clinical outcomes and investigating the results of biomechanic test.[Method]Forty-nine patients (included 52 knees) were treated by the standardized distraction apparatus and the comprehensive assessment standard was adopted to evaluate the clinical outcomes.Five patients were examined by three-dimensional CT of the knee joints pre-operatively and post-operatively to observe the changes in the knee structure.To observe the effect of distraction on the popliteal artery and the limb nerves,the popliteal artery diameter and blood flow speed were examined in 15 patients and the regio cruris electromyogram and nerve conduction velocity were examined in 6 patients before and after treatment.Three different means of distraction and measurement were underwent in 3 patients so as to observe the changes in the flexion curve and force of posterior soft tissues of the knee.[Result]All patients (52 knees) regained congruous structure and better function,the final excellent and good result rate was 65%.Three-dimensional CT examination of 5 patients showed that the postoperative knee joint structures were superior to the preoperative ones and there weren't damage of articular surface.The statistic results indicated that the popliteal arteries weren't obviously disturbed by distraction,whereas the limb nerves were probably disturbed temporarily.Three methods of distraction and measurement in 3 patients showed different outcomes,indicating that the effect of distraction on soft tissues was influenced by the distraction method,the ages of patients and the extents of deformities of the limb.[Conclusion]The distraction speed of therapeutic method is safe,reasonable and effective in correcting flexion contracture of the knee joint;The distraction force on posterior soft tissues of the knee is influenced by various elements,thus,the distraction speed should be individualized.Low-load and steady stretch are advantageous to soft tissue regeneration and safer.

Objective: To observe the efficacy of combined Chinese and Western medicines in the treatment of senile functional constipation. Methods: One hundred patients with senile functional constipation were divided into treatment group and control group. There were 50 in each group. The patients in the treatment group were treated with Danggui Shaoyao Decoction and Cisapride Tablets, while the patients in the control group were treated with Cisapride Tablets only. The efficacy in the two groups were compared after three courses. Results: The total effective rate of the treatment group was 92% and the control group's was 78%, the former was higher than latter with the comparatively significant difference (P < 0.05). Conclusion: The results indicate that the combination of Chinese and Western medicines is highly effective in the treatment of senile functional constipation.

Objective This research is to observe the treatment effects of hip bath and oxygen blowing on severe neonatal diaper rash.Methods 289 neonates with severe diaper rash were randomly divided into three groups.91 cases in the flat tube group,102 cases in the round tube group and 96 cases in the control group.Three groups of neonates were cleaned on the hips and perineuma after poops and then dried with wet tissues and Mupirocin Ointment.The control group was treated with the above-mentioned method.The oxygen blowing groups were treated with hip bath of 1:5000 chameleon solution twice a day.Blowing the hips with oxygen five minutes every time after hip bath.The method of blowing oxygen was that oxygen humidifying containers as normal oxygen aspiration facilities was not filled with water,whose oxygen flowing volume standed at 10 L/min and whose tube blew at the afflicted parts until being dry.The oxygen blower held the oxygen exit and blowed at the afflicted parts in the round tube group and the oxygen blower flattened the oxygen exit and blew at the afflicted parts in the fiat tube group.The treatment effects will be compared among the three groups four days later.Results The cure period of the round tube group was obviously shorter than that of the control group,and the cure period of the fiat tube group was remarkably shorter than that of the round tube group.The total effective rate in the round tube group was obviously higher than that of the control group and the total effective rate in the fiat tube group was obviously higher than that in the round tube group.The difference had a statistical significance.Conclusions The treatment effects for the severe neonatal diaper rash with hip bath and oxygen blowing are remarkable and the oxygen blowing effects with fiat tubes are better than those with round tubes.

In the magnetic induction tomography(MIT) system,the electrical conductivity of biological tissue is direct proportion to the phase difference between the excitation signal and the detection signal.To obtain the image of the contribution of tissue's electrical conductivity,the system must have the function of phase detection with high accuracy.The paper focuses on the means of digital phase detection,including FFT method,the correlation method and the classic method,which are ultimately compared with analogue phase detection method.The experimental results show that FFT method and the correlation method,with low error level and high linearity,can better detect the phase difference with the level of 0.1?.The digital phase difference detection provides a kind of effective method for MIT system.

Objective To investigate the oral health status of preschool children in private kindergartens in Jiading District of Shanghai, and to analyze the relationship between dental caries and growth and nutrition. Methods From Apr. 2015 to Jun. 2016, 5 755 preschool children in private kindergartens in Jiading District of Shanghai were examined by oral examination according to the principle of informed consent. The height, weight, and hemoglobin level of the children were measured, and the effects of body mass index (BMI) and hemoglobin level on dental caries were analyzed. Results The dental caries rate of preschool children was 50.67% (2 916/5 755) in private kindergartens in Jiading District of Shanghai. The prevalence of dental caries was significantly decreased with the increase of BMI (P<0.01). The decayed, missing and filled tooth (DMFT) of children with obesity or thinness was significantly higher than that of normal children (P<0.05). The prevalence of dental caries and DMFT of children with anemia (hemoglobin level<110 g/L) were significantly higher than those of the normal children (P<0.05). Conclusion Dental caries is closely associated with growth and nutrition of preschool children in Jiading District of Shanghai.

The build-in low-pressure monolithic column combined with hydride generation atomic fluorescence spectrometry ( HG-AFS ) was employed for speciation analysis of fish meat. The sample pretreatment and separation approach could be accomplished within 30 min. The proper amount of fish sample was weighed and smashed into puree. The extraction solution composed of 10% HCl, 1% thiourea, and 0. 15% KCl was added before loaded into the automatic temperature controlled vertex system with 2000 r/min. The sample solution was separated through Merck monolithic column, with 3% ( V/V) acetonitrile, 30 mmol/L amonium acetate and 0. 03%(V/V) 2-mercaptoethanol (2-ME) as the eluent. The after-column eluent was digested by novel UV digestion device with pipeline sintered into the lamp, and then detected by hydrid-generation AFS. The rapid LC separation enabled fast mercury speciation of fish sample within 10 min. The different UV lamp digestion effects, eluent components, carrier gas, shield gas, lamp current, as well as PMT working power was optimized. Under the optimal conditions, the robust system achieved detection limits (DL) of 0. 15 μg/L and 0. 14 μg/L for methylmercury and HgⅡ, respectively. The RSD (n=7) was less than 5%, the linear correlation coefficient was 0 . 999 , and the matrix spiked recovery was in the range of 85%-110% for Hg speciation. This method was used for the determination of Hg speciation in fish and soil samples, and was proofed to be a reliable, easy approach for daily inspection.

Objective To analyze the causes of the complications in the treatment of limb deformities with the Ilizarov technique and to discuss the management and prevention of these complications.Methods From January 2000 to October 2010,846 patients with limb deformities (16 upper limbs and 830 lower limbs) who had been treated with Ilizarov technique were retrospectively analyzed,including 508 males and 338 females with an average age of 25.7 years (range,1.2-72).Statistical analysis was used to compare the type,severity,treatment methods and results of complications.Results Postoperative follow-up lasted for 6 to 30 months,with an average of 18 months.There were 81 cases of pin tract infections,36 cases of restricted joint movements,6 cases of skin thermal damage,7 cases of nerves and vessels injury,8 cases of bone delayed union,2 cases of osteofascial compartment syndrome,7 cases of dislocation,5 cases of fixed needle breakage,8 cases of secondary joint deformities,5 cases of serious osteoporosis,6 cases of skin eruption,4 cases of femoral fractures near to proximal external fixator,3 cases of subsequent fracture after external fixator dismantled,11 cases of deformity recurrence and 1 case of the others.Combining with anti-infection,functional training,physiotherapy,and the second operation therapy and so on,a permanent disability was finally left in 13 patients.Conclusion If the Ilizarov technique was used improperly,there would be multiple complications during the preoperative preparation,surgical procedures and postoperative management.Effective preventive measures should be taken,such as following the principle of the Ilizarov technique,standardizing operation procedures,strictly postoperative observation,correcting postoperative rehabilitation exercise guidance,regular follow-up radiography and postoperative adaptability dynamic adjustment of the external technique.

?AIM: To evaluate the clinical effects, corneal surface shape and corneal thickness variation after treated by Danzhi Xiaoyao Capsule combined with hypromellose 2910, dextran 70 and glycerol eye drops for dry eye in menopausal patients.?METHODS: Eighty menopausal patients ( 160 eyes ) diagnosed as dry eye were randomly divided into groups A and B ( 40 patients each ) . Group A was treated with hypromellose 2910,dextran 70 and glycerol eye drops only and group B was treated with Danzhi Xiaoyao Capsule and eye drops. Before and 1mo after treatment, the clinical effects were evaluated by symptom scores, fluorescein staining ( FL ) , tear film breakup time ( BUT ) and Schirmer Ⅰ test. While the corneal surface regularity index (SRI), surface asymmetry index (SAI) and central corneal thickness ( CCT) were observed.? RESULTS: At 1mo after treatment, the symptoms scores and FL scores of the 2 groups decreased significantly( P<0. 05 ); BUT and SⅠt were significantly increased (P<0. 05). SRI and SAI gradually increased with dry eye exacerbations, after treatment the two parameters significantly reduced than those before treatment. SRI of group B improved significantly more than group A. CCT gradually got thinning with the dry eye condition worsened, which also significantly increased after treatment (P<0. 05);but there was no difference between 2 groups before and after treatment(P>0. 05).?CONCLUSION: Combination therapy of Danzhi Xiaoyao Capsule and hypromellose 2910, dextran 70 and glycerol eye drops for menopausal patients with dry eye is more effective than single eye drops, and can improve the symptoms and signs.
