Objective To detect serum concentration of folate receptor alpha and to investigate its significance in the clinical application of patients with endometrial carcinoma. Methods Thirty-seven patients with endometrial carcinoma, 33 patients with endometrial hyperplasia and 10 healthy women were enrolled in this study. Sera were used to detect the the folate receptor alpha using an Enzyme-linked Immunosorbent Assay (ELISA) technique.The expression level of serum folate receptor alpha in different groups was analyzed. The correlation between the expression level of serum folate receptor alpha and age of patients, menopause, tumor morphology, myometrial invasion and clinical stage was was also analyzed in patients with endometrial carcinoma. Results Level of folate receptor alpha was successfully detected in serum of healthy women and patients with endometrial diseases. Level of folate receptor alpha in patients with endometrial carcinoma was much higher than that in patients with endometrial hyperplasia. Level of folate receptor alpha in patients with endometrial hyperplasia was also higher than that in the healthy controls, with significant difference (P < 0.05). In the endometrial carcinoma group,the levle of folate receptor alpha in serum was correlated with the clinical stage and myometrial invasion (P < 0.05), however, Level of folate receptor alpha was not correlated with the age of patients, menopause andtumor morphology(P > 0.05). Conclusion The Serum level of folate receptor alpha can be detected, and its expression will contribute to the diagnosis, treatment and predicting the prognosis of patients with endometrial carcinoma.

Constipation has become a common clinical symptom in the elderly. Many factors can result in constipation, including diet,physiological aging, lack of exercise, inappropriate medication, psychological factors, perianal disease, and so on. If the individualized, targetedand comprehensive care interventions that consist of health education, psychological intervention, dietary intervention, medicationguide, functional exercise, passive attention to bowel training and abdominal massage etc. are done well, it can decrease the incidence ofconstipation, reduce a variety of complications and adverse effects caused by the constipation and improve the quality of life in the elderly.So it has important clinical significance.

Objective To evaluate the effects of different doses of dexmedetomidine administered intranasally on the median effective concentration (EC50) of sevoflurane inhibiting responses to laryngeal mask airway (LMA) insertion in the pediatric patients.Methods American Society of Anesthesiologists physical status Ⅰ or Ⅱ pediatric patients of both sexes, aged 1-3 yr, with body mass index of 20-25 kg/m2, scheduled for elective surgery under general anesthesia, were randomly divided into 3 groups: control group (group C) , dexmedetomidine 1 μg/kg group (group D1) , and dexmedetomidine 2 μg/kg group (group D2).In D1 and D2 groups, dexmedetomidine 1 and 2 μg/kg (in 1 ml of normal saline) were administered intranasally at 1 h before induction of anesthesia, respectively.Group C received the equal volume of normal saline administered intranasally.The children were separated from their parents at 45-60 min after intranasal administration and admitted to the operating room.The children inhaled 8％ sevoflurane until they lost consciousness.After loss of consciousness, the end-tidal concentration of sevoflurane was determined using the modified Dixon's up-and-down method.The initial end-tidal concentration of sevoflurane was set at 2％.The concentration was increased/decreased by 0.2％ in the next patient according to the response to LMA insertion.The patient's sedation status and with LMA acceptance were evaluated, and the patient's satisfaction with sedation and with LMA acceptance was recorded.Probit analysis was used to calculate the EC50 and 95％ confidence interval of sevoflurane inhibiting responses to LMA insertion.Results The patient's satisfaction with sedation and with LMA acceptance was significantly higher in D1 and D2 groups than in group C, and in group D2 than in group D1 (P＜0.05).The EC50 (95％ confidence interval) of sevoflurane inhibiting responses to LMA insertion was 2.03％ (1.91％-2.15％), 1.76％ (1.65％-1.87％) and 1.63％ (1.53％-1.73％) in C, D1 and D2 groups, respectively.The EC50 was significantly lower in D1 and D2 groups than in group C, and in group D2 than in group D1 (P＜0.05).Conclusion Dexmedetomidine 1 and 2 μg/kg administered intranasally can decrease the EC50 of sevoflurane inhibiting responses to LMA insertion in the pediatric patients, and 2 μg/kg produces better efficacy.

BACKGROUND:Bone cement used in the vertebroplasty treatment of osteoporotic vertebral compression fractures is nonabsorbable and has stronger intensity than normal bone tissue, which can cause further fractures of adjacent segments. OBJECTIVE:To investigate the short-term effect of vertebroplasty with artificial bone in the treatment of osteoporotic thoracolumbar fractures. METHODS:A total of 21 patients with osteoporotic vertebral compression fractures were enrol ed, including 7 males and 14 females, aged 61-89 years old. Al the patients were subjected to vertebroplasty with calcium sulfate injection. Visual analog scale and Oswestry Disability Index assessment were used before and at 0, 24, 48 weeks after treatment;meanwhile, X-ray and CT were used to observe the fil ing and leakage of artificial bone. RESULTS AND CONCLUSION:After treatment, al the patients showed improvements in the scores of visual analog scale and Oswestry Disability Index (P<0.01). X-rays and CT scans showed that there were three cases of leakage but without spinal cord and nerve compressions. After 3 months, most of the artificial bone was absorbed. These findings indicate that vertebroplasty with artificial bone can ease pain and improve living conditions of patients with osteoporotic vertebral compression fractures.

We examined the effects of intracerebroventricular ( i. c. v) administration of adrenomedullin (ADM) on catecholaminergic neurons and the expression of c-fos gene in rat brain nuclei involved in cardiovascular regulation using double immunohistochemical method for Fos and tyrosine hydroxylase (TH). The results showed that: ( 1 ) Following icy administration of ADM (3 nmol/kg) , double-labeled neurons for Fos and TH were significantly increased in the area postrema ( AP), the nucleus of the solitary tract ( NTS), the nucleus paragigantocelluaris laterialis (PGL) and the locus coeruleus (LC). (2) Pretreatment with calcitonin gene-related peptide receptor antagonis CGRP8-37 (30 nmol/kg) significantly reduced the action of ADM (3 nmol/kg) in the brain. The present study suggested that ADM might activate the neurons of the brain nuclei involved in cardiovascular regulation, and supported the hypothesis that the central action of ADM were induced by activating the catecholaminergic neurons of brainstem nuclei involved in cardiovascular regulation, CGRP receptor might mediate the effects of ADM.

Objective To evaluate the feasibility of virtual touch tissue quantification (VTQ) for the assessment of renal allograft.Methods A total of 72 kidney recipients were examined with conventional ultrasound and VTQ after transpantation.Biopsies were performed in 34 patients,20 patients were with acute rejection (AR),14 with chronic allograft nephropathy (CAN),38 patients as control group.The peak systolic velocity (PSV) and resistance index(RI) were measured on main,infrarenal and arcuate arteries with conventional ultrasound and shear wave velocity (SWV) of the renal cortex was obtained by VTQ.All the data were compared among three groups.Results There were no significant differences of PSV between two groups.An increased RI was presented in the CAN group(P ＜0.05).The mean SWV was (2.67 ± 0.27) m/s,(2.90 ± 0.31)m/s and (2.28 ± 0.24)m/s for AR,CAN and normal group,respectively.There were significant differences of SWV among the three groups (P ＜ 0.05).Conclusions VTQ technique could provide a new method for the assessment of transplanted kidney.

Background and purpose:New treatment strategies should be explored for non-small cell lung cancer (NSCLC) patients after the failure of the epidermal growth factor receptor-tyrosine kinase inhibitor (EGFR-TKI). To compare the efficacy and toxicities of chemotherapy in combination with EGFR-TKI or single chemotherapy in advanced NSCLC patients with EGFR-TKI resistence. Methods:In this study, 18 patients were enrolled. Eight patients were treated by chemotherapy combined with EGFR-TKI (CE group);10 patients were treated by single chemotherapy (E group), 21 days for one cycle. All patients received at least 2 cycles of treatment. Results:All 18 patients had been evaluated. The CE group was similar to the E group in objective response rate (ORR:25%vs 10%, P=0.832). The CE group was higher than the E group in disease control rate (DCR:87.5%vs 30%, P=0.046). The median PFS was longer in CE group (3.5 months vs 2.4 months, P=0.05). The CE group was higher than the E group in rash (75%vs 10%, P<0.05). The grade 3-4 toxicities did not have significantly differences between the two groups (P>0.05). Conclusion:Though there was no significant difference in ORR between the 2 groups (P>0.05), the CE group was superior to the E group in DCR and PFS. Patients with retreatment of advanced NSCLC after the failure of EGFR-TKI can be controlled by continued EGFR-TKI and chemotherapy.

1. The blood supply of the tensor fascia lata myocutaneous free flap comes chiefly from the ascending branch of the lateral circumflex artery (76.74％) or its ascending and the transverse branches (23.26％). In most cases the ascending branch may be served as the vascular pedicle of myocutaneous free flap in transplatation. In a few cases the transverse branch my be used instead of the ascending one.2. The projection of the origin of the lateral circumflx artery on the body surface is at a point averaging 96.5mm below, and 49.2mm medial to the anterior superior iliac spine. This point is the surface landmark of the lateral circumflex artery. 3. The branches of the lateral circumflex artery may be classified into four types. Type 1—32 cases, 74.42％; Type Ⅱ—3 cases, 6.98％; Type Ⅲ—7 cases, 16.28％; Type Ⅳ—1 cases, 2.33％.4. The tensor fascia lata is chiefly supplied by the ascending branch of the lateral circumflex artery, it divides into a short superior and a long inferior twigs. Both twigs enter the muscle and form abundant anastomoses in the subcutaneus tissues. In order to reduce the thick ness of the free flap for the use in plastics, the superior twig with its supplying muscle is cut away and the inferior one's left to supply myocutaneus flap.5. The angle between the ascending branch and the inner surface of the tensor fasca lata varies between 44? to 120?, with an average of 66.5?. The original angle must be kept in transplantation, which favours the survival of the myocutaneus free flap.

The origin, pattern, caliber, projection on the body surface and anastomoses of the cutaneous arteries within the lateral thoracic flap have been studied in 33 cases (sides): adults- 30 cases, children- 3 cases. The chief results are as follows:1. Four types of cutaneous arterial supply within this flap be divided according to the number of branches: one branched type(51.51%?8.70), two branched type(27.27%?7.75), three branched type(15.15%?6.24), four branched type(6.06%?4.15).2. Lateral thoracic cutaneous arteries may arise from one to four of the brachial, lateral thoracic, axillary, dorsal thoracic, subscapular or thoraco-acromial arteries. The caliber of their origin varies between 1.23～1.75mm. The thoracoepigastric vein which drains blood into the lateral thoracic vein may be regarded as the main cutaneous vein in the flap area. The caliber of its end is 3.35?0.42 mm. This vein provided with valves.3. There are plenty of cutaneous arterial anastomoses within the lateral thoracic flap. In the radiograph the networks of blood vessels may be seen among the branches of the cutaneous arteries. These networks are distributed over the whole flap.4. The blood vessels of the lateral thoracic flap and its application have been discussed and the position of skin incisions and landmark of the cutaneous arteries been proposed in the article.
