[ABSTRACT]OBJECTIVETo investigate the expressions of Endoglin (CD105) and Galectin-3 protein in laryngeal squamous cell carcinoma (LSCC) as well as the relationship between their expressions and the clinicopathological factors of LSCC.METHODSThe expressions of CD105 and Galectin-3 protein were detected in 76 samples of LSCC and 25 normal laryngeal tissues (NLT) by immunohistochemical staining (S-P).RESULTS 1.The mean of Microvessel density (MVD) value marked by CD105 in LSCC was 10.33±2.29, which was significantly higher than that in NLT (1.20±1.04) (P<0.05). The expression of MVD marked by CD105 (CD105-MVD) was correlated with histological grading, T stage, clinical stage, lymph node metastasis, recurrence and prognosis in LSCC (P<0.05). 2.The positive expression rate of Galectin-3 protein in LSCC was 86.84%, which was significantly higher than that in NLT (36%)(P<0.05). The expression of Galectin-3 was correlated with T stage,clinical stage, lymph node metastasis, recurrence and prognosis in LSCC (P<0.05). 3.There was a positive correlation between CD105 and Galectin-3 protein. 4.Survival analysis indicated that the expressions of CD105 and Galectin-3, histological grading, lymph node metastasis,T stage and recurrence were independent factors for tumor prognosis in LSCC (P<0.05). CONCLUSIONThe expressions of CD105 and Galectin-3 protein have a positive correlation in LSCC. They may play important roles in the tumorigenesis, malignant progression and poor prognosis of LSCC. Combined detection of them may be great value in diagnosis and predicting prognosis of LSCC.

A reasonable and practicable quality standard was developed for mori liquid extract from different sources by TLC, HPLC and fingerprint technology. In TLC method, the compounds were separated on polyamide film using glacial acetic acid-water (1: 3) as mobile phase at a UV wavelength of 365 nm. All qualified samples had the spots of the same color as the control herb and substance. The RP-HPLC method was used to determine the content of mulberroside A with mobile phase of methanol-water (25: 75) at a wave-length of 326 nm. The mulberroside A was in good linear with a regression equation of Y = 46.965X (r = 0.999 6) in the range of 4.6 - 228 mg x L(-1). In 14 batches of samples, the mulberroside A in 4 batches of them was less than 0.5 g x L(-1), and was more than 2.0 g x L(-1) in the other batches. It was suggested that the content limit of mulberroside A should be no less than 1.5 g x L(-1). The HPLC fingerprints were evaluated by the similarities. It has found that the similarities of different mori liquid extracts were very low and the chemical diversity of mori cortex was the major factor of similarity. Moreover, the process impact was minimal. Thus the fingerprint was not included in this quality standard.

OBJECTIVEThe purpose of this study is to study the sealing ability and the furcal appearance of repairing subpulpal wall perforation with resinous inlay.

METHODSFifty newly extracted human molars were randomly divided into three experiment groups (group A, group B, group C, 15 teeth each) and one control group (5 teeth). In experiment groups, perforations were made perpendicularly to the center of the pulp chamber floor. Perforations of group A and B were repaired with resinous inlay and sealed by AH Plus sealer and luting glass-ionomer, respectively. Perforations of group C were directly repaired using light-cure composite resin. Perforations were not made in five teeth of control group. The furcal appearances were evaluated under stereomicroscope after repairing. Microleakage was measured by glucose oxidase detection.

RESULTSThe fineness rate of furcal appearances with resinous inlay repairing were 83.3%, while the fineness rate of furcal appearances with light-cure composite resin directly repairing were 46.7%. There were statistics difference between resinous inlay repairing and light-cure composite resin directly repairing (P<0.05). There were statistics difference among the daily microleakage of three experiment groups, group A

CONCLUSIONUsing resinous inlay to repair the subpulpal wall perforation can improve the sealing effect and avoid material overextension. AH Plus can be used as perforation sealant because of its better sealing ability.

Objective To analyze the complications of radical vaginal hysterectomy in patients with locally bulky cervical cancer.Methods All 258 patients of early cervical cancer (stage Ⅰ A2-Ⅱ A) selected in our hospital during the period of June 2011 to June 2016 undergoing radical vaginal hysterectomy and laparoscopic pelvic lymph node dissection were analyzed.All cases were divided into observation (locally bulky) and control (conventional) groups.Comparison analysis was performed for complications of the two groups and the influence of neoadjuvant chemotherapy on the complications of local bulky patients.Results The incidence of complications in the observation group was 26 cases (27.9％),higher than that in the control group of 28 cases (17.0％),the difference was statistically significant (P ＜ 0.05).The incidence of bladder injury (5 cases vs 2 cases) in observation group was significantly higher than that in control group (P ＜ 0.05).For patients with locally bulky early cervical cancer,the incidence rate of complications of the neoadjuvant chemotherapy group (15.8％) was significantly lower than the simple operation group (36.4％) (P ＜ 0.05).The incidence rate of ureteral injury in neoadjuvant chemotherapy group (0 cases vs 6 cases) was significantly lower than that in simple operation group (P ＜ 0.05).Conclusions Early cervical cancer patients with locally bulky (stage Ⅰ B2/ 1Ⅱ A2) had higher incidence of complications of radical vaginal hysterectomy,and neoadjuvant chemotherapy can reduce the incidence of surgical complications.

AIMTo study the effect of conjugated linoleic acid (CLA) on obese MSG mice with insulin resistance.

METHODSAbout four months old, obese MSG mice with insulin resistance were divided into control, CLA and rosiglitazone groups and drugs were administrated ig once a day. Body weights were recorded regularly, insulin and glucose tolerance were tested. In addition, serum insulin and TNF-alpha concentrations in serum and fat tissues were determined.

RESULTSCLA was shown to reduce the body weight and fat weight in MSG mice, but can not improve the abnormal insulin and glucose tolerance in these mice. Indeed, the serum insulin and TNF-alpha concentrations in the fat tissues of the group treated with CLA were higher than those in the models and the insulin sensitivity index was significantly lower than that in the model mice.

CONCLUSIONCLA can reduce the body weight of MSG mice, but can not improve the insulin resistance in these mice.

OBJECTIVE: To improve the surgical outcome of pituitary adenomas by identifying and preserving the pituitary stalk and the gland during surgery. METHODS: From October 2010 to September 2012, the author from the Department of Neurosurgery of Xiangya Hospital, Central South University operated on 51 patients with pituitary adenoma. During the operations, we carefully identified the normal adenohypophysis, pituitary stalk, neurohypophysis and the abnormal tissues either by direct observation or by medical images, aiming to excise the tumor thoroughly, protect the pituitary function and reduce the postoperative complications. RESULTS: Totally 37 patients (72.5%, 37/51) had total resection of the tumor, 12 (23.5%, 12/51) had subtotal tumor resection and the other 2 had major removal. The gland and the pituitary stalk were well identified and reserved. Detection of hormone content proved that the operation had little effect on the free triiodothyronine (FT3) and adrenocorticotropic hormone (ACTH), while for free tetraiodothyronine (FT4) and thyroid stimulating hormone (TSH) and postoperative followup significant alleviation was found. There was no significant fluctuation for the testosterone in the men preoperatively and postoperatively (all the above results were obtained without hormone replacement therapy). The main postoperative complications were as follows: temporary diabetes insipidus in 5 patients (9.8%, 5/51); electrolyte disorder (the appearance of hyponatremia) in 17 (33.3%, 17/51); and cerebrospinal fluid rhinorrhea and postoperative intracranial infection in 1 (2%, 1/51). No one died during the perioperation period. CONCLUSION Microscopic transsphenoidal surgery is effective for pituitary adenomas including tumors violating the cavernous sinus. Accurate identification of the pituitary stalk, the gland and the abnormal tissue during the microscopic transsphenoidal operation plays a critical role in preserving the pituitary function and promoting postoperative rehabilitation.
