Tianjin Medical Journal 2014;(3):257-259
Objective To investigate the expressions of AKT and ERK1/2 proteins in hypopharyngeal squamous cell carcinoma and normal hypopharyngeal mucosa. Methods The expressions of AKT and ERK1/2 proteins were exam-ined by immunohistochemical S-P technique in 60 patients with hypopharyngeal squamous cell carcinoma and 15 cases of normal hypopharyngeal mucosa . The relationship between expressions of AKT and ERK1/2 proteins and clinical pathologi-cal feathers was analyzed. Results The positive rates of the expressions of AKT and ERK1/2 were 78.3% (47/60) and 66.7%(40/60) in 60 cases of hypopharyngeal squamous cell carcinoma, which were significantly higher than those in 15 cas-es of normal hypopharyngeal mucosa [13.3%(2/15) and 6.7%(1/15), P<0.05]. The lower the degree of differentiation, the later the clinical stage, the higher the positive expression rates of AKT and ERK1/2. There were significantly higher expres-sions of AKT and ERK1/2 in patients with lymph node metastasis than those of patients without lymph node metastasis (P<0.05 or P<0.01). There was a positive correlation between expression levels of AKT and ERK1/2 (rs=0.400,P<0.05). Con-clusion There were higher expression levels of AKT and ERK1/2 in hypopharyngeal squamous cell carcinoma. The activa-tion of AKT and ERK1/2 proteins promotes hypopharyngeal occurrence, development and metastasis.

OBJECTIVE:
To detect the expression of ERβ in laryngeal carcinoma and the its correlation with the expression of epithelial-mesenchymal transition(EMT) specific biomarkers.
METHOD:
Picture MT-Pv9000 was used to detect ERβ and EMT in 72 cases of human aqueous laryngeal carcinoma and 8 cases of adjacent non-neoplastic laryngeal mucosa by immunohistochemistry.
RESULT:
The positive rates of ERβ in tumors and adjacent non-neoplastic laryngeal mucosa were 27.78% and 25.00%, respectively. The differences were not significant (P > 0.05). The abnormal expression rates of E-cadherin and β-catenin were 61.11% and 76.39% respectively. The expression of ERβ correlated negatively with the loss of E-cadherin, nuclear translocation of β-catenin and increased TNM stage. The differences were significant (P < 0.05).
CONCLUSION
The positive expressions of ERβ suggest a good prognosis in the differentiation, clinical stages and lymphatic metastasis of the laryngeal carcinoma. The underlying mechanism may be related with the abnormal expressions of E-cadherin and β-catenin.

OBJECTIVE:
to explore the relationship between the maxillary sinus volume and the amount of alveolar bone, and the effect of molar loss upon the maxillary sinus was further analyzed,by measuring adult maxillary sinus volume, sinus ridge distance, and calculating the gasification coefficient of maxillary sinus.
METHOD:
One hundred and ninety cases (361 maxillary sinus) with CT examinations were collected, they were divided into group A and group B, 121 cases (242 maxillary sinus) of normal subjects served as group A, 42 cases (65 maxillary sinus) with molar part off were B group, in which 31 maxillary sinus with a molar loss were group B1,22 maxillary sinus with two molar loss were B2 group,12 maxillary sinus with three molar loss (one molar remains) were B3 group, 27 cases (54 maxillary sinus) with upper teeth off were C group. Bymeasureing the maxillary sinus volume, sinus ridge distance and the size of the maxillary sinus, calculating the gasification coefficient, we analyzed the relationship between maxillary volume and sinus ridge distance, and comparatively analyzed the differences among the three groups in the size, gasification coefficient, volume of maxillary sinus and sinus ridge distance.
RESULT:
In the normal group,the volume of maxillary sinus and sinus ridge distance had a correlation coefficient of -0. 63,(P< 0.05); Sinus ridge distance in group A was larger than the other two groups (P<0.05), and larger in B group than in C group (P<0. 05), anteroposterior maxillary sinus diameter and reft-right diameter in C group was greater than in A group and B group(P<0.05), group C gasification coeffiecent was less than A group and B group (P<0. 05).
CONCLUSION
The volume of maxillary sinus is negatively correlated with the amont of alveolar bone; Upper teeth's shedding promotes maxillary sinus deformation; Maxiuary sinus volume has a tendency to decrease.

BACKGROUND: Conventional means in treatment of distal tibiofibular syndesmosis disruption include plaster cast or splint immobilization as external fixation and internal fixation using screws, and bone bolts or plates;however, some disadvantages such as unstable fixation and uncertain fixation exist.OBJECTIVE: To observe the primary clinical curative effect of newly self-developed fixation, Hook-plate fixation (HPF), for distal tibiofibular syndesmosis disruption and its biochemical characteristics of HPF.DESIGN: Self-control observation.PARTICIPANTS: We recruited 23 patients with sustaining abruption of lower tibiofibular ligament union with fibular fracture who received treatment in the Department of Orthopedics, Affiliated Hospital of Yangzhou University Medical College, between October 2001 and March 2004. According to the Lauge-Hansen classification system, there were 11 cases of supination-lateral rotations, 7 cases of pronation-lateral rotations and 5cases of pronation-abductions. Among them 14 had bimalleolar fractures and 9 had trimalleolar fractures.METHODS: HPF was used on the 23 patients with distal tibiofibular syndesmosis disruption. Radiographs were taken routinely. Talocrural joint function exercise was recommended at week 1 and partial weight bearing was allowed 2 months later. Functions were evaluated according to modified Mazur's criteria (excellent, good, fair and poor).MAIN OUTCOME MEASURES: ①Healing time and function ev aluation after operation for distal tibiofibular syndesmosis disruption. ② Adverse events and side effectsRESULTS: Totally 23 patients entered the result analysis, with the mean of 11 months' follow-up. ①Results of healing time and function evaluation in the patients after operation for distal tibiofibular syndesmosis disruption: The healing time of fracture ranged from 12 to 18 weeks: 16 cases were excellent, 5 good, and 2 fair. ② Adverse events and side effects:There was no separation of the tibiofibular space, the distance between medial malleolus or lateral malleolus and anklebone was symmetrical.There was no mobilization or rupture of the internal fixation after operation.CONCLUSION: HPF is applied in treating distal tibiofibular syndesmosis disruption. It causes no postoperative complications, and can recover the ankle joint function with stable internal fixation and good biomechanical features.

Objective To investigate the hospitalized patients incidence of nutritional risk and nutritional support in six departments (general surgery, thoracic surgery, gastroenterology, neurology, urology and respirology) in a middle hospital and in the medical/surgical departments in a small hospital, so provide reference for rational nutritional support for patients. Method Nutritional Risk Screening 2002 was used to assess the existence of nutritional risk and the necessity of nutritional support. Results The overall prevalence of the nutrition risk was 25% in the six departments in the middle hospital; more specifically, the prevalence of nutrition risk arranged from 18% to 31% in these six departments: 31% in the department of respiratory medicine, 29% in the department of neurology, 27% in the department of urology, 23% in the department of thoracicsurgery, 22% in the department of gastroenterology, and 18% in the department of general surgery. For those at nutritional risk, the nutritional support rate was 24%. For non-risky patients, 9% received nutritional support. The overall prevalence of nutrition risk was 18% in the small hospital; more specifically, the prevalence of nutrition risk was 29% in the department of internal medicine and 7% in the department of surgery. For those at nutritional risk, the nutritional support rate was 24%.For non-risky patients, the nutritional support rate was 4%. Conclusions Certain nutritional risk and malnutrition exist in inpatients in the middle and small hospitals in Shijiazhuang. The applications of parenteral and enteral nutritions still have some problems. It is of particular importance to further promote the application of evidence-based parenteral/enteral nutrition guidelines in middle and small hospitals to standardize the application of nutritional support.

OBJECTIVE:
Evaluating the function of the internal jugular vein after selective neck dissection on patients affected by squamous cell carcinoma of the head and neck by color Doppler ultrasonography.
METHOD:
Forty patients (76 internal jugular veins) who had undergone bilateral selective neck dissection(36 patients) or unilateral selective neck dissection (4 patients) were collected and divided into 2 groups depending on operation area. Group A consisted of 39 internal jugular veins (IJVs) which dissected level II, III and group B included 37 IJVs which disseted level II - IVor II - V spring the IJV. All patients underwent Doppler ultrasonography before and after selective neck dissection at the 1st and 3rd postoperative months. The following measurements were assessed in each test: presence of thrombosis, expiratory jugular flow, expiratory caliber, area both during expiratory and Valsalva maneuver, expiratory flow speed, Valsalva flow speed. All data were statistically analyzed in two groups by comparisons of preoperative conditions and postoperative conditions.
RESULT:
(1) None of the 76 internal jugular veins showed thrombosis before or after selective neck dissection. (2) Patency rate at the 1st and 3rd postoperative months were respectively 85.5% and 96.1%. Patency rate of the internal jugular vein in two groups showed no significant changes at the 1st and 3rd postoperative months (P > 0.05). (3) In group A, Valsalva flow speed showed no significant changes at the 1st postoperative months (P > 0.05), compared with preoperative; The remainings showed significant difference. Expiratory calibe, area during Valsalva maneuve, expiratory flow speed and Valsalva flow speed had significant difference at the 3rd postoperative months (P < 0.05), compared with preoperative. In group B, Valsalva flow speed showed no significant changes at the 1st postoperative months (P > 0.05), compared with preoperative; The remainings showed significant difference. Expiratory jugular flow had no significant difference at the 3rd postoperative months (P > 0.05), compared with preoperative; The remainings showed significant difference. All parameters at the 3rd postoperative months had significant difference compared with 1st postoperative months between these two groups, excepting expiratory flow speed. (4) Differences of the operation area had no significant impact on indications of the internal jugular vein (P > 0.05).
CONCLUSION
(1) None of the internal jugular veins showed thrombosis after selective neck dissection. The results indicate that thrombosis of the internal jugular veins can be avoided though careful operation, proper operative skill, appropriate management postoperation. (2) Although most of the parameters changed at early stage after selective neck dissection, many of them improved at the 3rd postoperative months, and expiratory jugular flow recovered to the normal range. The results indicate that the internal jugular veins can basically maintain its normal function at long time postoperation.

OBJECTIVE:
To evaluate the relation between the incidence of sinusitis and the position of the inferior border of the middle concha related to the semilunar hiatus.
METHOD:
Clinical data of 94 cases (185 sides of paranasal sinus) diagnosed by CT detection, operative findings and clinical features were analyzed. The middle concha was divided into 3 types according the position of its inferior border related to the semilunar hiatus: superior hiatus type (the inferior border of the middle concha superior to the semilunar hiatus), hiatus type (the inferior edge of the middle concha at the level of the semilunar hiatus) and inferior hiatus type (the inferior edge of the middle concha inferior to the semilunar hiatus). Statistic analysis were taken for comparing the incidence of sinusitis among the position of the middle concha and other anatomical variations such as deviation of nasal septum, pneumatization of middle concha, paradoxical curve of the middle concha, variations of the uncinate process, ethmoidal bulla enlargements, Haller cells and agger cell pneumatization.
RESULT:
There was no significant difference of the anatomic variations by comparing the superior hiatus type together with the hiatus type versus the inferior hiatus type (P > 0.05). But the incidence of sinusitis in each type was remarkably different, the superior hiatus type and hiatus type had more sinusitis than the inferior hiatus type. Furthermore, the second and third type of sinusitis in the superior hiatus type and hiatus type weighted over the inferior hiatus type (P < 0.01), while the first type didn't (P > 0.05).
CONCLUSION
There is no association between the position of the middle concha and the anatomic variations of the nasal cavity and paranasal sinus. The poorly developed middle concha may acts as a risk factor for sinusitis and nasal polyps.
