Objective To define the risk period of acute pancreafifis-associated lung injury (APALI) by aserial study including a dynamic changes in total water content of lung, ultrastructure and number of type Ⅱ alveo-lar epithelial, and reactive oxygen metabolisms (ROMs) of lung tissue in mice with severe acute pancreatits (SAP)and a clinical analysis of APALI patients. Method ICR mice were selected to establish SAP model. The animalsreceived 7 intraperitoneal injections of caerulein (50 μg/kg body weight) at hourly intervals followed by intraperi-toueal injection of lipopolysaccharide (15 mg/kg body weight). The total water content, uhrastrueture and numberof type Ⅱ alveolar epithelial cells, and ROMs of lung tissue were detected before (0 h) and 6 hours, 12 hours,lday, 4 days and 7 days after SAP model establishment, respectively. In addition, 215 patients with APALI (PaO2< 60 mmHg) collected from the First Affiliated Hospital of Zhejiaug University between January 1998 and Decem-ber 2006 were analyzed. Statistical analysis were performed by using F-test. P-values less than 0.05 were regardedas statistically significant. Results The total water content and ultrastructure mitochondria and lamellar bodies intype Ⅱ alveolar epithelial cells of lung in SAP mice were significantly altered at 12 hours after SAP model estab-lishment, and reached maximum at 1 to 4 days later. A decrease in number of type Ⅱ alveolar epithelial cells andincrease in ROMs reached a maximum at 1 day after SAP model establishment. Furthermore, the results of clinicalstudy showed that the lung injury occurred at (3.1435±1.0199) days after SAP. The data were almost consistentwith the resalts from SAP model. Conclusions The risk period of APALI occurres between the 1st day and the4th day during the course of SAP.

We retrospectively analyzed 218 allergen skin prick tests ( SPT ) of the patients with chronic sinusitis with or without nasal polyps( CRSwNP/CRSsNP) before the operation. The proportions of positive SPT in CRSwNP and CRSsNP were compared respectively. The distributions of allergens were the same in all groups. The positive rate of SPT in CRSwNP was higher than that in CRSsNP, with statistical significance(P<0. 05). The positive rate of SPT in CRSsNP was higher than that of the control group, without statistical significance. The recurrence rate in CRSwNP was higher than that in CRSsNP, with statistical significance. The recurrence rate in the allergen-positive patients was higher than the allergen-negative patients, with statistical significance.

Objective To introduce a new computer-assisted external frame for osteotomy to correct complex tibial and fibular deformity.Methods From January 2012 to December 2013,15 patients with complex tibial and fibular deformity were treated with a computer-assisted external frame and related computer software for surgical correction.All were unilateral limb deformity,involving the left lower limb in 8 cases and the right lower limb in 7 cases.They were 8 males and 7 females,15 to 43 years of age (average,26.8 years).The deformity was caused by old osteomyelitis in 9 cases and trauma sequela in 6.The related angles,distances and rotations were measured on the postoperative radiographs of the lower limbs.The data were input into the software to calculate the daily adjustment lengths of the frame rods.Daily frame adjustments were conducted according to the data calculated.The frame was removed when expected results were achieved.The patients lived independently during the adjustment.Results The 15 patients were effectively followed up for 10 to 22 months (average,15 months).Frame fixation time averaged 8.4 months (from 5.5 to 13.1 months).The reunion time averaged 8.0 months (from 5.4 to 12.1 months).The hospitalization time averaged 2.4 months (from 2.0 to 2.8 months).In 10 cases of limb shortening,the shortening lengths averaged 0.5 cm (from 0 to 0.9 cm) after adjustment.In 12 cases of angulation deformity,the angulation averaged 3.3° (from 0° to 5.4°) after adjustment.In 5 cases of rotation deformity,the maximum internal rotation was 5° and the maximum external rotation 10° after correction,deviating from the normal values by 3.5° on average.In 6 cases of horizontal displacement,the displacements averaged 0.5 crn after correction.All patients were satisfactory with corrected lower limb alignment,improved symptoms and appearance,giving a subjective satisfaction rate of 100％.Conclusion Use of computer-assisted external frame in surgical correction of tibial and fibular deformity can achieve satisfactory outcomes in simple,accurate,standardized,minimally invasive manners.

Objective To establish a method to isolate and cultivate rat bone marrow mesenchymal stem cells (BMSCs),and explore the feasibility of labeling in vitro,and tracing in vivo,BMSCs with chloromethyl-benzamidodialkylcarbocyanine (CM-Dil). Methods BMSCs were obtained and subsequently cultured with whole bone marrow cell culture system,and the third generation of BMSCs was harvested. The positive rates of CD34,CD44 and CD29 were detected by flow cytometry. CM-Dil was used to label BMSCs in vitro and the efficiency of labeling after 24 hours and at day 21 and 30 were examined under fluorescent microscope. Moreover,the growth curves were sketched to determine the negative effects of CM-Dil on the vitality and proliferation of BMSCs cultured in vitro. Rat model of focal cerebral ischemia was reproduced,CM-Dil labeled BMSCs were implanted into corpus striatum of rats' brain with computer-guided stereotaxis thereafter. Brain tissues were obtained to prepare frozen sections at 7th,14th and 21st day post-implantation,and the survival and distribution of labeled cells were observed with fluorescent microscopy. Results The third generation passage of cultured BMSCs grew orderly,with shape of desmocytes,and homogeneous in morphology. The positive rates of CD34,CD44 and CD29 expressions in BMSCs were 1.71%,80.32% and 84.89%,respectively. Red fluorescence was observed in CM-Dil labeled BMSCs in vivo 24 hours after labeling,with a positive rate of 100%. The fluorescence intensity of passage cultured BMSCs observed on day 21 was similar to that observed at 24 hours after labeling,but diminished on day 30. The growth,proliferation and morphology of BMSCs,were not influenced by CM-Dil labeling. On day 7,14 and 21 post-implantation,BMSCs decreased in quantity,appearing in oval or irregular shapes,and most of the cells were found around the needle tract,with a tendency of diffusion to peripheral area. Conclusion High purity of BMSCs may be obtained with whole bone marrow cell culture system from bone marrow of rats. CM-Dil labeling is easy to handle and effective,with no cytotoxicity to cells. The latest labeling period of CM-Dil is 21 days in vitro,therefore it seems to be an effective method for in vivo tracing of BMSCs in brain after implantation.

OBJECTIVE:To understand the situation of essential medicines and promote their rational use in our hospital. METHODS:The prescription variety and cost percentages of essential medicines in outpatient department in the two halves years of 2013 in our hospital(eye and ENT specialized hospitals)were compared;the medicines with forefront prescription kind percent-ages in eye and ENT departments were sorted and rankings in 4 quarters were compared. RESULTS:After the approval of the Na-tional Essential Medicine List(2012 edition),compared with the first half year of 2013,prescription variety and cost percentages of essential medicines in outpatient department in the second half year were significantly increased (P<0.01). Prescription variety and cost percentages of essential medicines in eye department in the second half year were significantly increased(P<0.01),in the top 20 prescription variety,totally 2 kinds were contained by the list 2012 edition and 3 were contained by the supplementary list of Shanghai(2012 edition). Compared with the first half year of 2013,prescription variety and cost percentages of essential medi-cines in ENT department in the second half year were significantly decreased(P<0.01),the cost percentage was significantly in-creased(P<0.01),in the top 20 prescription variety,totally 2 kinds were contained by the list 2012 edition and 3 were contained by the supplementary list of Shanghai (2012 edition). CONCLUSIONS:The prescription variety and cost percentages of essential medicines in our hospital show increase trend. Nevertheless,the non-essential medicines are still dominant and further improvement of essential medicines is still needed. Medicine variety and dosage forms of eye in ENT department are insufficient concluded in Es-sential Medicine List. Further adjustment of Essential Medicine List still needs more consideration for the medication characteristics in specialized hospital.

[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 explore the methods and effect of using Ilizarov'techniques for correcting severe flexion contracture of the knee joint.[Method]According to Ilizarov's tension-stress principle and its applying technique,the knee joint distraction apparatus was designed and fixed individually.The joint hinges of the apparatus on the two sides were consistent with the rotational center of the knee joint.Joint distraction of 5 to 10 mm was initially performed and followed by gradual correction of the knee joint flexion contracture at an average rate of 1 mm per day at the level of the knee joint by turning the nuts on the distraction rods at 3～4 rounds per day,with the distraction rate modified according to the patient's tolerance.Regular x-ray exams should be carried out to prevent knee joint dislocation and compression of the articular cartilage.The final requirement of correcting the soft tissue flexion deformity of the knee joint was to overcorrect the joint deformity into 5～10 degrees of hyperextension.As for the joint flexion with anterior bowing deformity of the distal femur,the degree of correcting the knee joint flexion contracture should deduce the degree of the bony deformity.The frame was left on for an additional 2 to 4 weeks.When the frame was removed,the knee joint was immediately casted in full extension for 3 to 4 weeks followed by the range of motion exercise on CPM to regain the knee motion and a long-leg brace was provided simultaneously to maintain the correction for 3 months.Secondary osteotomy was performed on anterior bowing deformity of the distal fermur in 8 patients.[Result]More than 30 degrees of severe flexion contracture of knee joint (mean?sd 58.50?21.28?) in 49 patients (52 knees ) were corrected to an average of 4.12?4.61 degrees after treatment.40 joints of 38 cases were followed for an average of 6.8 months,in which 28 joints maintain the postoperative effect.,while 12 joints had partial relapse of 9.30??8.24?.[Conclusion]Ilizarov's technique for correcting severe flexion contracture of the knee joint,can have satisfactory effect with little complications.It is mini-invasive,reliable and safe.
