OBJECTIVETo evaluate clinical results of plate on the metatarsal side to reconstruction of tarsometatarsal joint dislocations secondary to diabetic charcot foot.

METHODSSeven patients (9 feet) patients with tarsometatarsal joint dislocations secondary to diabetic charcot foot were treated with plating from April 2012 to December 2014. All patients were male, and 5 cases were on the unilateral side and 2 cases were on the bilateral sides. The age of patients ranged from 45 to 52 with an average of 48 years old. The history of diabetics was from 6 to 15 years. X-ray and CT were used to evaluate fractures healing,and AOFAS was applied to estimate recovery of joint function.

RESULTSAll patients were followed up from 12 to 24 months with an average of 19 months. All incisions were healed at stage I . No infection, loosening and breakage of internal fixation, bone nonunion were found after operation. According to postoperative X-ray and CT results, the time of fracture healing ranged from 10 to 20 weeks with an average of 16 weeks. Six feet got excellent results, 2 good and 1 moderate based on AOFAS scoring.

CONCLUSIONTarsometatarsal joint dislocations secondary to diabetic charcot foot treated with plate on the metatarsal side could obtain stable fixation and got satisfied early clinical results.

BACKGROUND: The commonly used culture methods for primary intervertebral disc cells are type Ⅱcol agenase alone digestion method, and type Ⅱ col agenase combined trypin digestion method. However, the acquired cells are few. OBJECTIVE: To acquire nucleus pulposus cells from human degenerative intervertebral disc using a systemic and simplified method. METHODS: Nucleus pulposus cells were isolated and cultured. The morphology of nucleus pulposus cells was observed under inverted phase contrast microscope every day. Primary and subcultured cellsuspension was applied for the determination of cel viability using trypan blue staining. The cel growth was detected with MTT assay. The cel morphology was observed under laser confocal microscopy. RESULTS AND CONCLUSION: Nucleus pulposus cells were successful y isolated from from human degenerative intervertebral disc using the improved method, and cells were subcultured to passage 3. Primary cells were fusiform shaped, while cells at passage 1 and 2 were triangle or polygonal, which were similar to fibroblasts. When cells almost reached the confluence, the cells showed slabstone-like appearance. Trypan blue staining showed that, the primary cel viability was 99%, and passage 3 cells had 93%-95% viability. The proliferation of nucleus pulposus cells gradual y decreased as the generation increased. Compared with passage 1 cells, passage 2 and 3 cells at logarithmic phase trended to be smoother. The cel morphology observed under laser confocal microscopy was similar to the results under phase contrast microscope. The improved simple method can successful y acquire a variety of cells from human degenerative intervertebral disc, and these cells show fine biological properties.

Objective To explore the cataract surgery quality on blindness prevention and postoperative problems in village in short period. Design Population-based survey. Participants 251 cases(254 eyes) received operation and 131 cases(134 eyes)were surveyed 6-month postoperatively. Methods Patients were examined 6-month after the small incision extracapsular cataract extraction and intra ocular lens(IOL) implantation. Examinations were conducted by a special oculist including far vision, near vision, external in- spection, anterior segment, posterior segment, intraocular pressure. Main Outcome Measures Visual acuity, intraocular pressure, diopter, eye complications of surgery. Results Naked far vision of the operated eye more than or equal to 0.3 was 41.8%, naked far vi- sion of the eye more than or equal to 0.05 was 82.8%; corrected far vision more than or equal to 0.3 was 64.2%, corrected far vision more than or equal to 0.05 was 92.3%. Naked near vision more than or equal to 0.1 was 79.9%, corrected near vision more than or e- qual to 0.1 was 85.8%. The main postoperative complications were ametropia, posterior capsule opacification(PCO), deformed pupil, pupil displacement, pigments of IOL, eccentric IOL and intraocular hypertension. The chief reasons of eyes that could not be recovered were vitreous, retina or optic nerve diseases, the key factors that caused living vision less than 0.3 were ametropia, PCO, the disease of vitreous, retina and optic nerve. Conclusions The serious complications affecting the surgery result are limited in a low range. The most important factors of the eye corrected far vision less than 0.05 are the vitreous, retina and optic nerve diseases. In order to improve the visual sight, we should add equipment to calculate the IOL diopter accurately.

Purpose To investigate the expression of GATA3 in breast tumors and its clinical significance. Methods Immunohisto-chemistry EnVision method was used to detect the expression of GATA3 protein in 132 cases of breast malignant tumor tissue, 29 cases of breast benign tumor tissue, 35 cases of breast carcinoma adjacent tissue. Besides, the GATA3 expression level was compared with several clinicopathological parameters. Result (1) All the breast normal tissues expressed GATA3, while 77% of the breast cancer tissue were found to be GATA3 positive. (2) GATA3 did not expressed in diffuse large B cell lymphoma and spindle cell malignant tumor of breast. (3) In the triple negative breast cancer, the expression of GATA3 was lower than that of any other subtypes of breast carcinoma (χ2 =29. 354, P<0. 001). Conclusion The positive expression of GATA3 is correlated to classification and grade in breast tumor. Detection of the expression of this biological maker may provide a valuable marker for the differential diagnosis and prog-nostic of breast carcinoma.

The compound that distributes in the herbs with one common effect was named as "co-effect compound" (CEC). The CECs of three traditional Chinese medicine(TCM) effects, purgative, relieving pain and clearing heat, had been found and studied. A strong corresponding relationship was found between the pharmacological activities of CECs and the TCM effect they belong to. The study shows that it may be a feasible method to connect traditional effect of TCM with modem pharmacological activity.

Purpose To investigate the clinicopathological and immunohistochemical features of primary small cell carcinoma of the cervix ( SCCC) and its prognosis. Methods 18 cases of primary cervical small cell carcinoma were evaluated by histopathology, in si-tu hybridization and immunohistochemistry and relevant literatures were reviewed. Results The age of the patients ranged from 30 to 69 years ( mean age, 40 years) . Major clinical manifestation was irregular colporrhagia. Colposcopy often revealed a cervical mass or cervical erosion. Microscopically, the tumor cells were small and round and arranged in a solid distribution. The cell had little cyto-plasm and increased karyoplasmic ratio with deeply stained granular chromatin and increased pathological mitosis. Immunohistochemi-cally, the tumor cells were often positive for CKpan, variable positive for Syn, NES, CgA, CD56 and p16. HPV 16/18 were positive in 4 cases. Conclusion SCCC is a neuroendocrine tumor of high malignancy and poor prognosis with a possible pathogenesis of HPV 16/18 infection. CKpan, Syn, CgA, NSE and CD56 are useful markers for the diagnosis of SCCC.

OBJECTIVETo explore the therapeutic effect and mechanism of Aitongping capsule (ATP) in treating cancerous pain.

METHODSSixty cancer patients were randomly divided into two groups, 30 patients in the treated group took ATP and 30 patients in the control group took diclofenac, 1 week of treatment was applied. The relevant clinical conditions of cancerous pain, the content of plasma beta-endorphin (beta-EP) and c-AMP, hemorheological index, improuement of life quality of patients, occurrence rate of adverse reaction were observed before and after treatment.

RESULTSThe total effective rate in the treated group and in the control group was 90.0 % and 83.3%, respectively, difference between them showed no significance. However, there were significant difference between the two groups in such aspects as the degree of pain relieving, the decrease of pain episodes, the shortening persistent time of pain and the initiation time of analgesic action and prolonged analgesic duration, the decrease of tenderness and percussion pain, the increase of plasma beta-EP content and the decrease of cAMP (P< 0.05 or P< 0.01). The evidences also showed that it was better in improving quality of life, ameliorating hemorheologic indexes and reducing incidence of adverse reaction in the treated group than in the control group (P <0.05 or P <0.01).

CONCLUSIONATP has affirmative effect on cancerous pain, its analgesic effect may be associated with the increasing of plasma beta-EP content, decreasing of cAMP level and ameliorating of hemorheologic indexes.

BACKGROUND:It is unclear whether short-term high-intensity interval training (HIT) can be used to protect against myocardium injury after acute myocardial infarction, as wel as the underlying mechanism.
OBJECTIVE:To observe the effects of short-term HIT on the ventricular remodeling and mitochondrial content after acute myocardial infarction, and the biological effect of mitochondrial biogenesis and autophagy in this process.
METHODS:Male Sprague-Dawley rats were modeled into acute myocardial infarction by ligating coronary artery. One week later, HIT was performed:each interval consisted of 4-minute high-intensity running (80%of maximal oxygen consumption) and 3-minute active recovery (40%of maximal oxygen consumption), for 4 consecutive weeks of 5 days each week, repeated 7 cycles.
RESULTS AND CONCLUSION:Four-week HIT after acute myocardial infarction could markedly enhance left ventricular pump function and mitochondrial content, improve mitochondrial membrane potential and ATP synthetic activity, inhibit mitochondrial reactive oxygen species generation, up-regulate PGC-1α/Tfam induced mitochondrial biogenesis and Bnip3/Beclin-1 induced autophagy. These results indicate that short-term HIT can improve normal mitochondrial content after acute myocardial infarction, which in turn ameliorates myocardial systolic property and energy metabolism. As a cardiac rehabilitation method, HIT exhibits fine timeliness.
