2.Mechanism and Treatment of Muscle Spasticity after Spinal Cord Injury(review)
Chinese Journal of Rehabilitation Theory and Practice 2006;12(7):559-562
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.

4.Clinical significance of serum procalcitotin in children with Kawasaki disease at acute stage
Tianjin Medical Journal 2017;45(1):43-46
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.

Objective To establish stable Graves disease (GD) mice models with immunization and electroporation (EP).Methods Fifty mice were divided into 3 groups by random number table method:experimental group (n =30),control group (n =10),blank group (n =10).Recombinant plasmid pcDNA3.1/hTSHR268 was constructed and injected to bilateral gastrocnemius in experimental group mice on the 1st,4th,7th and 10th week.The same volume of normal saline was injected in the control group and blank group at the same time.Both experimental group and control group were subjected to EP at the same time and the same location to enhance immunization.Serum T4 was tested with radioimmunoassay.TRAb N-terminal (TRAb N) and TRAb C-terminal (TRAb C) antibodies were tested with ELISA.Whole body 99TcmO4-imaging was performed and then thyroid morphology and pathology were investigated.Data were analyzed by one-way analysis of variance and the least significant difference (LSD) t test.Results GD BALB/c mice models were built successfully (80%,24/30).Serum T4 increased from (16.06±5.16) nmol/L at the basic level to(95.04±68.92) nmol/L on the 12th week(F=18.906,t=-5.598,P<0.05).Serum TRAb N antibody increased from (0.006±0.002) U/L at the basic level to (0.251±0.110) U/L on the 12th week(F=47.491,t=-10.869,P<0.05).Serum TRAb C antibody increased from (11.176±2.635)×103 arbitrary unit (AU)/L at the basic level to (46.395±22.001)× 103 AU/L on the 12th week(F=14.642,t =-7.787,P<0.05).On the 18th week serum T4,TRAb N and TRAb C decreased to (36.64±23.68) nmol/L,(0.094±0.053) U/L and (24.456±6.725)× 103 AU/L respectively,which were still higher than those preimmune levels(t=-4.161,-8.085,-9.008,all P<0.05).There were no significant change of T4,TRAb N and TRAb C in the control group and blank group.After 4 times of immunization,the 99TcmO4-uptake by thyroids in immunized mice increased.The thyroid glands of immunized mice showed enlargement.Microscope examination showed that there were lymphocytes infiltration,colloid decrease and epithelial cell proliferation in thyroids of immunized mice.Conclusion GD mice models were successfully established by injecting recombinant plasmid pcDNA3.1/hTSHR268 and EP.

Objective To explore the effects of modified radical surgery combined with chemo-therapy on postoperative complications and quality of life in breast cancer patients.Methods The clinical data of 175 patients with early breast cancer were retrospective analyzed.According to the different ways of surgical treatment,patients were divided into the control group(n =100)and the study group(n =75).In the study group,patients received modified radical mastectomy,and preoperative and postoperative chemo-therapy as adjuvant therapy.In the control group,patients received traditional standard radical surgery.The follow-up ranged from 1 to 3 years.Recurrence,mortality,postoperative complications,and quality of life were compared between the two groups.Results There were no significant differences in local recurrence (6.7% vs 6%)and axillary lymph node recurrence (2.7% vs 3%),distant metastasis (10.7% vs 11%),and 5-year survival rate(92% vs 91%)between the study group and control group(P >0.05).In the study group,the incidence of postoperative complications was significantly lower(6.7% vs 42%), while its score on quality of life significantly improved(P <0.05).Conclusion For early breast cancer, modified radical mastectomy combined with chemotherapy has similar effects as the standard radical mas-tectomy.It has obvious advantages in reducing complications and improving the quality of life,which is worthy of being spread clinically.
