Muscle spasticity is one of the common complications in the paraplegic patients who suffer from spinal cord injury (SCI). Spasticity can result in limbs pain, joint contracture and malformation, then affects walking and the capability of keeping the posture in wheelchairs. Moreover, spasticity can increase the incidence rate of heterotopic ossification and fracture and seriously affects patients' daily life and rehabilitation therapy accordingly. There are many kinds of treatments aimed at spasticity at present, such as drug, exercise therapy, physiotherapy, nerve block treatment, operation treatment, and so on. However, single treatment doesn't achieve good effect. So it is common that many kinds of treatments are combined to treat spasticity. This article simply introduces the mechanism, symptom and evaluation of the muscle spasticity after SCI and discusses in full the treatment of the muscle spasticity by reviewing recent literatures.

Objective To investigate the changes and clinical significance of serum procalcitonin (PCT) level in children with acute phase of Kawasaki disease (KD). Methods The serum PCT levels and their changes before and after the treatment in 120 children with KD at acute phase were retrospectively analyzed. According to the results of ultrasonic echocardiography, all children were divided into coronary artery damage (CAL) group and no coronary artery lesion (NCAL) group. According to the presence of gastrointestinal symptoms, patients were divided into two groups (A: yes and B: no ). According to the presence of abnormal liver function, patients were divided into two groups (C:yes and D:no). PCT levels were compared between groups. Results The serum PCT levels were increased at acute phase in 56 (46.67%) patients before the treatment than those in normal children, which were decreased obviously after treatment (P<0.05). There were 31 cases combined with CAL, the rising rate of PCT was 38.71%, which was no significant difference compared with that of NCAL group (49.44%, P>0.05). There was no significant difference in serum PCT value between CAL group and NCAL group (P>0.05). The serum C-reactive protein level was significantly higher in CAL group than that of NCAL group. There were 35 patients combined with gastrointestinal symptoms in 120 KD patients. There was no significant difference in the rising rate of PCT between patients with gastrointestinal symptoms (62.86%) and patients without gastrointestinal symptoms (40.00%, P<0.05). There was no significant difference in serum PCT level between these two groups of patients. There were 42 cases with liver dyfunction in 120 KD patients, the PCT rising rate (52.38%) was no statistically significant difference compared with that of patients with no liver dyfunction (43.59%, P>0.05). And there was no significant difference in serum PCT value between the two groups (P>0.05). Conclusion PCT can reflect the acute phase of KD patients. The increased PCT level may be related with the emergence of gastrointestinal symptoms, even though it cannot predict CAL and the occurrence of liver damage.

OBJECTIVETo study the effect of ethyl acetate fraction of Blumea balsamifera (BBE) residue on treating rats of adjuvant arthritis (AA) and its mechanism.

METHODThe rats were immunized with the Freund's complete adjuvant (FCA). After modeling, 28 days' treatment with BBE was performed. During the experimental process, rat mass, toe girth, arthritic index (AI), proliferation of immune organs and pathological section were measured. After treatment, blood samples were collected through fossa orbitalis vein for detection of serum SOD, MDA, GSH, NO, OH*, ALP, AST, ALT, NAG and SA content using colorimetric method and IL-1, IL-6, TNF-α content using ELISA method.

RESULTAdministration with BBE (high dose) could significantly ameliorate joint swelling and arthritis index, effectively inhibit synovial hyperplasia, down-regulate the levels of MDA, NO, OH*, ALP, AST, ALT, NAG, SA, IL-1, IL-6, TNF-α and up-regulate the SOD and GSH levels in serum.

CONCLUSIONThe results suggested BBE possesses substantial anti-arthritis and antioxidant activities.

Antibiotics being currently the most extensively used medicine in clinical practice and abuse of them being prevalent, it is thus necessary to monitor in an effective and systematic manner the rational use of them. Based on the existing database and network of hospital information system, a monitoring system for the rational use of antibiotics was successfully developed using the development tool of PowerBuild. This functionally powerful and easy-to-use system, which provides comprehensive and reliable information, improved work efficiency and managerial level by automatically monitoring many chief indicators of antibiotic usage, including dosage, resistance, combination with other drugs, course, pathway, usage during the perioperative period, usage for preventive purposes, therapeutic effect, and the ratio of hospital infection occurrence resulting from the use of antibiotics under different circumstances.

Digestive tract reconstruction after proctocolectomy is a critical step of colorectal surgery, proper reconstruction can promote the recovery of digestive tract function and improve the quality of life.At present, there are some candidate reconstruction methods after proctocolectomy, but standardized and proper one is not still established.Since there are differences of the reconstruction methods after proctocolectomy at the different parts of colorectum, the best reconstruction methords should be selected according to the condition and intraoperative situation of patients.

AIM:To compare the short-term and long-term curative effect between two implantation methods for treating refractory glaucoma.METHODS:A total of 150 patients with refractory glaucoma (150 eyes) were divided into Group A (treated by implantation with Ex-press glaucoma drainage device) and Group B (treated by implantation with Ahmed glaucoma valve) according to different implantation methods.Changes of intraocular pressure and anti-glaucoma drugs at different time points, the success rate of surgery, improvement of visual acuity and complications were compared between the two groups.RESULTS:The intraocular pressure of two groups at 1d, 1wk, 3, 6 and 12mo after surgery was significantly lower than that before surgery (P<0.05).The intraocular pressure of Group A at 3, 6 and 12mo after surgery was significantly lower than that of Group B, while anti-glaucoma drugs at 6 and 12mo after surgery were significantly fewer than those in Group B at the same time point (P<0.05).There were no significant differences between the two groups in 12-month success rate of operation, improvement rate of visual acuity and incidence of postoperative complications (P>0.05).CONCLUSION:The effects of implantation with Ex-press glaucoma drainage device are similar to those of implantation with Ahmed glaucoma valve in the treatment of refractory glaucoma.However, the intraocular pressure control effect of the former is better than the latter, and used anti-glaucoma drugs are fewer.

The development of laparoscopic techniques has made surgical treatment enter into the era of minimally invasive surgery,and the application of three-dimensional (3D) high-definition laparoscopic system has brought the important innovation for laparoscopic techniques,meanwhile,it also provides stereoscopic visions and more accurate spatial orientation for surgeons.During the process of laparoscopic radical resection of lower rectal cancer,3D vision can help to identify blood vessels,nerve and tissues around the rectum,ensure accurate lymph node dissection,reduce difficulty of operation,and the learning curve of laparoscopic radical resection of lower rectal cancer for inferior surgeons might be shorten by using 3D imaging system.With the development of technology,the value on clinical application of 3D high-definition laparoscope will become more evident.

[Objective] To study the methods of inducing bone mesenchymal stem cells(BMSCs)of rabbits into chondrocytes in vitro and the interaction of transforming growth factor ?1(TGF-?1),insulin-like growth factor-Ⅰ(IGF-Ⅰ)and basic fibroblast growth factor(bFGF).[Methods]BMSCs of rabbits were primarily cultured and subcultured in vitro,and then divided into four groups according to the difference of factors:group A receiving TGF-?1 and bFGF;group B receiving TGF-?1 and IGF-Ⅰ;group C receiving TGF-?1;group D receiving no cell growth factor.After three weeks all the four groups were detected by methyl thiazolyl tetrazolium(MTT)assay,measurement of glycosaminoglycan(GAG)and immunohistochemistry.[Results]Immunohistochemical detection of collagen Ⅱ was positive in groups A,B and C.The results of the MTT assay and the GAG content in groups A and B were obviously higher than those in groups C and D.[Conclusion]Rabbit BMSCs can be induced into chondrocytes under certain conditions.TGF-?1,IGF-Ⅰ and bFGF have synergy effect in the differentiation from BMSCs into chondrocytes.
