Objective To explore the clinical value of the dynamic change of serum carbohydrate antigen 125 (CA125) in the evaluation of the therapeutic effect and prognosis in patients with epithelial ovarian cancer (EOC).Methods The clinical data of 84 patients with EOC were retrospectively analyzed.The change of before and after treatment,the half-life of CA125,the relationship between the clearance time of CA125 and the survival time and recurrence of patients were investigated.Results After operation,the serum level of CA125 was significantly lower than that before treatment(t =11.306,P ＜0.01).After 6 cycles of standard chemotherapy,the serum CA125 again decreased evidently(t =6.265,P ＜ 0.01).In the half-life of CA125 (T1/2) ≤ 20d group,the survival time was significantly longer than T1/2 ＞ 20d group(t =3.394,P ＜ 0.01).Compared with CA125 negative conversion time(NT) ＞ 8 weeks group,the survival time of NT ≤ 8 weeks was significantly longer (t =2.791,P ＜ 0.01),the recurrence rate was significantly lower(22.9％ vs.58.3％) (x2 =10.941,P ＜0.01),the recurrence time was later(t =15.965,P ＜0.01).Conclusion The dynamic change of CA125 has important clinical value in the evaluation of the therapeutic effect and prognosis of patients with EOC.EOC patients with short CA125 half-life,faster negative conversion time have better treatment effect,longer survival,lower recurrence rate after operation.

Objective To investigate the clinical and imaging characteristics of tumor like inflammatory demyelinating disease of CNS, We have analyzed the reason of misdiagnosis, and summed up the main point of differential diagnosis.Methods We have analyzed 14 cases which were confirmed as demyelinating disease in pathology after the operation, and all the clinical and image data were included.Results CNS inflammatory demyelinating disease could present edema and mass effect by CT or MRI, there was ring potentialization after enhancement, it was difficulty to distinguish from CNS demyelinating disease. All the 14 patients were misdiagnosis as CNS tumor before the operation.Conclusion CNS inflammatory demyelinating disease could have some atypical representation on CT or MRI image, they were made easily the misdiagnosis. We should get the differential diagnosis by many ways including clinical manifestation, course, laboratory examination and imaging characteristics.

Objective To analyze clinical characteristics of 8 cases of MELAS syndrome that misdiagnosed as herpes simplex virus encephalitis(HSE).Methods The clinical data of 8 cases of MELAS syndrome that misdiagnosed as HSE were reviewed retrospectively.Results The main manifestations of 8 cases were repeated fever,progressive mental impairment,seizures,headache,descent of eyesight and hearing,weakness of extremities.Fever was the common symptom in the 8 cases.Exercise tolerance dose of serum lactic acid levels studied in 8 cases were obviously abnormal.Imaging examinations showed laminar necrosis or atrophy in brain lobes and basal ganglia areas.Electroencephalogram(EEG) mainly showed diffused slow waves,1 patient displayed myogenic injury in electromyogram(EMG).Muscle biopsy showed red ragged fibers and abnormal mitochondria in all cases.Conclusions The clinical manifestations of MELAS syndrome are similar to HSE,but EEG and imaging results are obviously different from HSE.Exercise tolerance dose of serum lactic acid and muscle biopsy are important for diagnose of MELAS syndrome.

Objective To study the clinical characteristics and differential diagnosis of Miller-Fisher syndrome (MFS) and Bickerstaff's brainstem encephalitis (BBE).Methods The clinical data of 12 patients with diagnosis of MFS and 15 patients with diagnosis of BBE were analyzed retrospectively.Results In MFS group, the patients showed diplopia (12 cases), loss of pupillary light reflex (3 cases), peripheral facial paralysis (7 cases), hydroposia bucking (1 case), weakness of limbs (6 cases), sensory disability (4 cases) and ataxia (10 cases). In BBE group, the patients presented with diplopia (11 cases), central facial palsy (4 cases), tinnitus (4 cases), hydroposia bucking (6 cases), weakness of limbs (10 cases), sensory disability (2 cases), ataxia (10 cases), somnolence or coma (5 cases) and positive Babinski's sign (9 cases). CSF examination showed elevation of protein in 10 patients from BBE group and 10 patients from MSF group, however, leucocytosis was found in 6 cases from BBE group and 2 cases from MSF group. There were 4 patients of MFS and 1 patient of BBE with abnormal results of electromyogram (EMG) examination. 6 patients in BBE group had abnormal results of CT or MRI examinations, and the lesions mainly located in brainstem, thalamus and so on. Both groups had good prognosis after therapies. Conclusions MFS and BBE have similar and overlapped clinical characteristics. This indicates that these two diseases are closely related and may form a continuous spectrum. The main identifications of BBE are conscious disturbance, positive reflex of Babinski's sign and abnormal imaging results in some patients.

To elucidate the change in trunk muscle performance in patients with low back pain caused by military training. The indices of trunk muscle strength (PT/BW, TAE, F/E, ER), the cross-sectional area of sacrospinalis, the amplitude and the duration of EMG, and the lumbar curvature were measured in recruits with low back pain after military training (n=40)and healthy subjects(n=40).All of the indices were compared between two groups. It was found that except PT/BW and ER of flexors and cross-sectional area of sacrospinalis, there were significant differences between other indices of the patients compared with healthy subjects(P

Objective\ To observe the practicality of sonography for differentiating the compression factors and judging whether thorough decompression anterior to the dura sac has been obtained. Methods Posterior midline incision was used in a total of 16 cases. After the laminae were resected, normal saline was poured into the operation field, and ultrasound examination performed with a 5.0 MHz sectorscanner. Combined with preoperative imaging (CT or MRI),the compression factors were differentiated. The isolated tissue(bone or disc)pieces in spinal canal were removed first,then reduction of approximate and distal parts of the injuried spinal column was obtained with the help of the Dick devices. Posteriorly protruded bone mass was tumbled in carefully supervised with sonography. The sonographic criterion for thorough decompression consisted of the reappearance of the anterior subarachnoid and an even and smooth echo of posterior dura mater. Results\ The sonographic criterion for thorough decompression was achieved in all cases. No bone mass posterior displacement was observed on postoperative rontgenogram or CT examination. Partial or complete recovery of neural function was obtained in 13 cases. Conclusion\ All elements contributing to anterior dura sac compression can be readily recognized by sonography,which offers a reliable criterion for complete decompression.

To ascertain the change of trunk muscle strength and lumbar curvature and cross sectional area of M. sacrospinalis in low back pain caused by military training, the indexes of trunk muscle strength (PT/BW, TAE, F/E) were measured in patients with low back pain and healthy subjects with CYBEX 6000 isokinetic testing system. The lumbar curvature was measured in lumbar X ray films on the lateral projection in standing position, and the cross sectional area of sacrospinalis was measured by ultrasonography. All of the indexes were compared between the two groups.The results showed PT/BW of flexors was not significantly different between the patients and healthy subjects, TAE of flexors in patients was lower than that of healthy subjects ( P

BACKGROUND:Mesenchymal stem cels can secrete a variety of cytokines and growth factors that promote the survival of surrounding cels and play a paracrine role. OBJECTIVE:To investigate the effect of human umbilical cord mesenchymal stem cels on the proliferation and apoptosis of ectopic endometrial cels. METHODS:After isolation and culture, human umbilical cord mesenchymal stem cels and ectopic endometrial cels were co-cultured as observation group, and ectopic endometrial cels cultured alone served as control group. At 24, 48, 72 hours of culture, the proliferation and apoptosis of ectopic endometrial cels were detected by MTT and flow cytometry, respectively; RT-PCR was used to measure the expression ofPTEN gene in ectopic endometrial cels. RESULTS AND CONCLUSION:At 24, 48 and 72 hours, the proliferation of ectopic endometrial cels in the observation was inhibited significantly as compared with the control group, and the hypodiploid peak ratio also increased significantly (P < 0.05). Over time, the cel inhibition rate was gradualy declined, and there were significant differences at different time points (alP < 0.05). Compared with the control group, the expression of PTEN gene was up-regulated significantly in the observation group (P < 0.05). In the observation group, the expression ofPTEN gene at 48 and 72 hours was significantly higher than that at 24 hours (P < 0.05). These findings indicate that in the human umbilical cord mesenchymal stem cels can inhibit the proliferation of ectopic endometrial celsin vitro and promote their apoptosis by up-regulation ofPTEN mRNA expression.
