Chinese Journal of Physical Medicine and Rehabilitation 2003;0(10):-
Objective To set up a new method of mild hypothermia via lateral ventricle in rabbits following traumatic brain injury (TBI). Methods Twenty-one New Zealand rabbits were used for this study. TBI was pro- duced with all the rabbits in anesthesia by using free-falling impact model. Animals were randomly divided into three groups: a TBI group, a mild hypothermia group (by perfusion of 25℃Ringer's solution via the lateral ventricle) and a control group. The contents of water and total sodium, potassium of the brain region close to traumatic brain tissue were detected and pathological changes were observed in three groups. Results The number of the injured neurons was increased significantly in both TBI group and mild hypothermia group than that in control group at 72 h after TBI (P

Forty-eight patients with subclinical Cushing's syndrome(SCS)were evaluated.Eleven of them underwent adrenalectomy(Group 1)and the other 37 cases did not(Group 2).Serum and urine corticosol, plasma ACTH and parameters related to metabolic syndrome(such as waist circumference,blood pressure,blood lipids and fasting plasma glucose)were measured.The data at diagnosis were compared with those during the survey.The results indicated that patients with SCS had a significantly high prevalence of metabolic syndrome.The symptoms and signs of metabolic syndrome could be improved after removing the tumor.Otherwise there is no improvement,some patients will even develop into overt Cushing's syndrome.

A growing body of evidence has indicated the important role of autophagy receptors in directing ubiquitinated or non-ubiquitinated cargos towards autophagy. Autophagy receptors bind to LC3 (microtubule-associated protein 1 light chain 3) on phagophore and autophagosome membranes, and recognize signals on cargoes in the delivery system of autophagy. However, the diverse domains in the receptor structures determine that their roles would never be limited to autophagy. Up to date, increasing numbers of the receptor proteins have been demonstrated to serve as a molecular link or switch participating in autophagic degradation, apoptosis or cell survival signals. Here, we highlight the non-autophagic roles of these receptor proteins to draw attention to this growing research topic.

Objective To explore the effects of lycium barbarum polysaccharide (LBP) on restraining the mouse pancre?atic cancer cells LTPA by the polarization of macrophages to type 1 macrophages (M1). Methods LTPA tumor model of the subcutaneous CB-17SCID mice was constructed. Model mice were randomly divided into tumor-bearing model group (n=10) and LBP treatment group (n=10). The LBP treatment group was fed 10mg/kg LBP every day, and the tumor-bearing model group was fed the same dose of normal saline. The same amount of macrophages Raw264.7 was randomly divided into the control group and experimental groups (different concentrations of LBP). MTT assay was used to detect the optical density (OD) of Raw264.7 in experimental groups and control group. ELISA was used to detect the levels of the interleukin (IL)-12 and IL-10 in experimental group (LBP was 100 mg/L) and the control group. Flow cytometry was used to test the levels of the membrane protein CD16/32 and CD206 in experimental group (LBP was 100 mg/L) and the control group. The tumor mass was weighted and the volume was calculated after three weeks. The effects of LBP on the growth of subcutaneous tumor were detected. HE staining and KI-67 staining were used to detect the microscopic changes of tumor and the proliferation of the LTPA. Results The dose of 100 mg/L LBP can promote the growth of the macrophages Raw264.7 (P<0.01), and induced the high expression of CD16/32 and low expression of CD206, high secretion of IL-12 and low secretion of IL-10. The weight, volume of the tumor and the expression of KI-67 were significantly lower in experimental group than those in the con?trol group (P<0.01). The microscopic necrosis area range of tumor was larger than that of control group. Conclusion The LBP has the effect of restraining LTPA by the polarization of macrophages to M1.

Objective To evaluate the method and outcome of surgical treatment for refractory slow-transit constipation (STC). Methods Clinicopathologic data of 24 patients with severe STC which underwent (colectomy) in recent years were retrospectively analyzed. Results 18 of the patients underwent pancolectomy,and 6 underwent subtotal colectomy. All of the 14 STC patients complicated with outlet obstructive (constipation)(OOC) were corrected preoperatively by related surgery. The curative rate of surgical (treatment) was 95.8%,with an average of(3?1.9) times of bowel motion per day. The incidence of (abdominal) distention decreased from 75% to 12.5%. One patient who underwent ileorectal anastomosis (developed) recurrent constipation. Conclusions Colectomy produces satisfactory results in the majority of (patients) with refractory slow-transit constipation.Patients complicated with OOC should undergo energetic (preoperative) correction therapy,in order to ensure a satisfactory surgical outcome.

Objective To explore the incidence and pathologic feature of patients with thyroid carcinoma treated at the First Hospital of Jilin University. Methods From January 2000 to July 2010,clinicopathologic data of 1018 patients with thyroid carcinoma treated in the First Hospital of Jilin University were retrospectively analyzed. Results The cases of thyroid carcinoma between 2008 and 2010 were more than 73% higher than that in the preceding 8 years. Cancer cases from January 2009 to July 2010 were more1018 cases reviewed, 976 cases were clearly classified pathologically. Papillary thyroid carcinoma, follicular thyroid carcinoma, medullary thyroid carcinoma and anaplastic thyroid carcinoma were present in 897 (91.91%), 43(4. 41% ), 22(2. 25% ) and 6(0. 61% ) cases respectively. Of the 1018 cases reviewed,804 cases were recorded with or without lymphnode metastasis. The rate of lymphnode metastasis of male and female patient were 39. 24% and 28. 64% respectively and the difference was significant( χ2 = 6. 71 ,P <0. 05). The rate of lymphnode metastasis of age <45 years and age ≥45 years were 37.65% and 23. 26%respectively and the difference was significant ( χ2 = 19. 54, P < 0. 05 ). Conclusions In the past ten and a half years, the number of the thyroid carcinoma patients treated in the First Hospital of Jilin University increased year by year. The increase of papillary thyroid carcinoma was the most obvious. Thyroid carcinoma was more common among females. The peak incidence age of males and females was 30 -59. The rate of lymphnode metastasis of males was larger than that of females. The rate of lymphnode metastasis of age <45years was larger than that of age≥45 years.
