Hepatic endometriosis is a rare form of atypical endometriosis,only 30 cases were reported worldwide.Most cases of hepatic endometriosis were misdiagnosed due to the lack of typical symptoms.One patient with space-occupying lesions in the liver diagnosed by color Doppler ultrasonography were admitted to the Fuzhou General Hospital of Nanjing Military Command on November 5,2012.The patient was preliminarily diagnosed as with hepatic echinococcosis and then received operation.The result of postoperative pathological examination confirmed hepatic endometriosis.

ObjectiveTo observe the effect of acupoints stimulation with silver spike point therapy on insomnia.Methods60 patients with insomnia were randomly divided into the trial group and control group with 30 cases in each group. Patients of the trial group were treated by acupoints stimulation with silver spike point therapy and patients of control group were treated only with Clonopin. All patients of two groups were tested with Self-Rating Scale of Sleep (SRSS) before and after treatment.ResultsThe curative effect rate of the trial group was 86.6%; that of the control group was 60%; the curative effect of the trial group was superior to the control group (P<0.05). SRSS difference of the trial group pre-and post-treatment was 12.79±3.20; that of the control group was 10.1±3.89. There was also a significant difference between two groups (P<0.01).ConclusionThe silver spike point therapy has the better curative effect on insomnia than Clonopin.

Objective: To compare the efficacy of moxibustion with different doses for knee osteoarthritis (KOA), and explore the correlation between moxibustion dose and clinical efficacy. Methods: Sixty-eight patients with KOA who met the inclusion criteria were randomly divided into a 20-minute moxibustion group and a 40-minute moxibustion group by the random number table method, with 34 cases in each group. Dubi (ST 35), Neixiyan (EX-LE 4) and Heding (EX-LE 2) were used for moxibustion in the two groups. Each treatment lasted 20 min or 40 min for each point in the 20-minute moxibustion group and 40-minute moxibustion group, separately; the treatment was given 3 times a week and lasted for 4 weeks. The visual analog scale (VAS), Western Ontario and McMaster University osteoarthritis index (WOMAC) and traditional Chinese medicine (TCM) symptom scores were evaluated before and after treatment to compare the efficacy between different moxibustion doses for KOA. Results: After treatment, the total effective rate was 87.5％ in the 40-minute moxibustion group, versus 70.0％ in the 20-minute moxibustion group, and the difference in the total effective rate between the two groups was statistically significant (P<0.05). After treatment, the VAS scores, the total WOMAC scores and the component scores of pain, stiffness and dysfunction, and the TCM symptom scores in both groups all changed significantly when compared with those before treatment (all P<0.05). After treatment, the between-group differences in the VAS score, the total WOMAC score and the component scores of pain and dysfunction, and the TCM symptom score were statistically significant (all P<0.05), while the difference in the stiffness score in WOMAC showed no statistical significance (P>0.05). Conclusion: Either 20-minute moxibustion or 40-minute moxibustion can relieve pain, improve stiffness, dysfunction, and TCM symptoms for KOA; and 40-minute moxibustion is better in relieving pain, improving dysfunction and TCM symptoms.

OBJECTIVEThis work lays the foundation for establishing a digital model database with normal occlusion. A digital dental cast is acquired through grating projection, and model features are measured through reverse engineering.

METHODSThe grating projection system controlled by a computer was projected onto the surface of a normal dental model. Three-dimensional contour data were obtained through multi-angle shooting. A three-dimensional model was constructed, and the model features were analyzed by using reverse engineering. The digital model was compared with the plaster model to determine the accuracy of the measurement system.

RESULTSThe structure of three-dimensional reconstruction model was clear. The digital models of two measurements exhibited no significant difference (P > 0.05). When digital and plaster models were measured, we found that the crown length and arch width were not statistically different (P > 0.05), whereas the difference between the crown width and arch length was statistically significant (P < 0.05).

CONCLUSIONThe reconstruction of a digital model by using the grating projection technique and reverse engineering can be used for dental model measurement in clinic al and scientific research and can provide a scientific method for establishing a digital model database with normal occlusion.

BACKGROUND: Caspase family is viewed as the executive factor of cell apoptosis. Neuronal apoptosis happens probably after spinal cord injury.OBJECTIVE: To observe the changes in caspase-3 expression after spinal cord injury in rats so as to probe into the relationship between it and neuronal apoptosis and provide the evidence on the prop e r time window of intervention on alleviating secondary spinal cord injury.DESIGN: Self-control and mutual-control were designed in animal experiment.SETTING: Department of Traumatic Surgery and Department of Orthopedics of Tongji Hospital Affiliated to Tongji Medical College of Huazhong University of Science and Technology.MATERIALS: The experiment was performed in Experiment Room of Tongji Hospital affiliated to Tongji Medical College of Huazhong University of Science and Technology from January to December 2001, in which, 54SD rats were employed, of either sex, mass weighted varied from 220 to 250 g and provided from Animal Experimental Center of Tongji Medical College of Huazhong University of Science and Technology.rats were divided into the control and injury group. Laminectomy was only done on Ts and T9 in the control and the injury group was subdivided into 9 subgroups, in which, the materials were collected on the 4th and 8th hours and on the 1st, 2rd, 3rd, 7th 14th and 21st days successively, 6 rats in each one. After abdominal anesthesia with 30 g/L pentobarbitol sodium,sternal cord on T8 andT9 segments were exposed with Nystrom method and 50 g weight compressed the front middle region of the spinal cord of such segments with arch smooth metal pad 2.2 mn×5.0 mm for 5 minutes. After injury, artificial bladder urination was done 3 times at 10:00, 16:00and 22:00 successively everyday till the bladder reflex was established.cord was collected at various time spots after spinal cord injury. 4 pieces of spinal cord tissue masses from each group, about 8mm in length, were embedded with paraffin and sectioned continuously. Afterwards, HE staining, immunohistocheistry and TUNEL (TdT-mediated dUTP-biotin nick end labeling) were performed successively. Two rats were sacrificed on ice in each group and central tissue of injured spinal cord was placed in expression was assayed with immunohistochemistry method, neuronal apoptosis was assayed with TUNEL method and linear correlation was used to analyze the correlativity between caspase-3 expression and neuronal apoptosis.pase-3 expression after spinal cord injury in rats of each group.RESULTS: Six rats were maintained in each group and included in result optic microscope: Extensive hemorrhage appeared in 1 hour in injured segment. In 4 to 8 hours, spinal structure began destructive and a large amount of neuronal death appeared. In 24 hours, the destruction of spinal cord became severe and in 7 to 21days, the range of injury was defined with immunohistochemistry in rats of each group: Very few caspase-3 expressions (2.1±0.5) presented in neurons of spinal cord in normal rat. In 8hoursafter spinal cord injury, caspase-3 expression of positive neurons was increased remarkably (89.2±10.5) and up to the peak (189.6±12.7) in 3 days. Caspase-3 expression of positive cell and apoptotic cell appeared alexpression assayed with transcription-polymerase chain reaction (RT-PCR)in rats of each group: Caspese-3 mRNA (0.442±0.024) began increased in 4h, was up to the peak (0.634±0.028) in 48 hours and was restored to be normal (0.351±0.013) in 7 days, which appeared early than apoptosis, indicating positive correlation with the level of neuronal apoptosis (r=0.622).In the control and 4 hours group, stained cell was seen occasionally and positive cell appeared 8 hours later, mainly localized in gray matter. Afterwards, positive cell was increased and up to the peak in 3 days. In 7 days,positive cell of apoptosis and staining was decreased gradually in gray matter, mainly around the white matter. Little amount positive cells appeared on the 14th day and 21st day.CONCLUSION: In normal spinal cord tissue, caspase-3 existed in form of zymogen with very low activity. Caspase-3 is enhanced in expression after spinal cord injury in rats, expresses in large amount in 8 hours and is up to the peak in 24 to 48 hours, which is overlapped in time with positive apoptotic cell assayed with TUNEL and concerning to the localization, it is in conformity with positive apoptotic cell of spinal cord injury compared with positive cell of caspase-3. It is indicated that caspase-3 is involved in regulation of cell apoptosis after spinal cord injury. It is seen in this experiment that the time from spinal cord injury to the activation of caspase-3 is the time window of treatment for cell apoptosis intervened by spinal cord and alleviating secondary spinal cord injury. It is suggested that genetic intervention or specific caspase-3 inhibitor should be applied in 48 hours.

Purpose To discuss the value of MRI in the diagnosis of placenta implantation abnormality, and to explore preliminarily the relationship between MRI signs and types of placenta implantation abnormality. Materials and Methods The clinical preoperative data and postnatal pathological findings of 54 women at high risk of placenta accreta were collected. All the patients undertook the conventional pelvic MRI examination. The scanning sequences mainly included: sagittal, coronal and axial T2-weighted imaging-turbo spin echo, balance fast field echo. The MRI images were observed and the areas which showed low signal in all the three directions on T2WI were measured. Then the correlation between the areas of low signal on T2WI in placental and the types of placenta implantation abnormality was analyzed. Results The incidence of placenta implantation abnormality was 64.8% in our research (35/54). The main MRI signs were low signal on T2WI (68.5%, 37/54) and heterogeneous signal in placenta (57.4%, 31/54); the main sign of placenta percreta was tenting bladder (75.0%, 6/8). The types of placenta implantation abnormality were positively correlated with the areas of low signal on T2WI (r=0.454, P<0.05). Conclusion Pregnant women at risk of placenta accreta should be evaluated with imaging examinations, particularly with MRI scanning, to improve disease detection rate. The typical indirect signs of placenta implantation abnormality are low signal on T2WI and heterogeneous signal in placenta. The larger size of low signal area on T2WI in placenta, the deeper implantation of placenta.

Objective To investigate the effects of aerobic exercise during chemotherapy on cancer-related fatigue in breast cancer patients, and related mechanism thereof. Methods Sixty breast cancer patients who underwent radical surgery were randomly assigned to exercise group and control group, 30 patients for each group. Patients in exercise group received regular nursing care plus aerobic exercise during chemotherapy, while patients in control group only received regular nursing care. The revised Piper fatigue scale (RPFS) was used to assess the fatigue degree. Values of hemoglobin concentration(Hb), maximal oxygen uptake (VO2max) and RPFS scores were detected before chemotherapy, at the end of chemotherapy and 4 weeks after chemotherapy, respectively. Results There was no significant difference in Hb concentration before chemotherapy, at the end of chemotherapy and 4 weeks after chemotherapy between two groups (P>0.05). The level of Hb was significantly lower at the end of chemotherapy and 4 weeks after chemotherapy than that before chemotherapy in two groups (P<0.05). There were no significant differences in VO2max and RPFS score before chemotherapy between two groups (P>0.05). At the end of chemotherapy and 4 weeks after chemotherapy, there were no significant differences in VO2max and RPFS scores than those before chemotherapy in exercise group (P>0.05). In control group, value of VO2max was significantly lower at the end of chemotherapy and 4 weeks after chemotherapy than that before chemotherapy (P<0.05), RPFS score was significantly higher than that before chemotherapy (P<0.05). Conclusion Aerobic exercise during chemotherapy can be effectively against cancer-related fatigue, which may be related to the inhibitory effect of aerobic exercise on debasement of VO 2max.
