This paper first reports on systemic lupus erythematosus with galactorrhea.From May 1994 to April 1995,we checked 48 female in-patients,in whom we found 9 cases,aged from 20 to 45 years,with various degrees of galactorrhea.The serum prolactin levels of 9 cases with galactorrhea were 45.86?28.84ng/ml and those of the rest 39 cases without galactorrhea were 21.43?14.92ng/ml,P

Objective To explore the role of nucleotide-binding oligomerization domain receptor protein 3 (NLRP3) inflammasome in the pathogenesis of dementia. Methods 16 patients with with Alzheimer's disease (AD), 22 patients with vascular dementia (VD) and 20 healthy persons with similar age were detected the level of NLRP3 mRNA with RT-PCR in peripheral blood mononuclear cells January, 2014 to October, 2015. The serum level of interleukin (IL)-1βand IL-18 were detected with ELISA. The total number of white blood cells (WBC) and serum total calcium were collected. Single factor correlation analysis was performed between NLRP3mRNA and IL-1β, or IL-18, or WBC, or calcium concentration. Results The levels of NLRP3 mRNA ranged from high to low were as in AD group>VD group>the healthy group (q>11.48, P<0.05). The serum level of IL-1βwas higher in AD group than in the the healthy group (q=16.74, P<0.05), but not significantly different between VD group and the healthy group, nor between VD group and AD group (P<0.05). There was no signifi-cant difference about IL-18 among AD group, VD group and the healthy group (P<0.05). NLRP3 mRNA was positively correlated with the serum levels of IL-1β(r=0.64) and calcium (r=0.58) in AD group. There was no correlation between NLRP3 mRNA and IL-18 or WBC (P<0.05). Conclusion The expression of NLRP3 inflammasome may be related with the pathogenesis of AD, but little impact on the pathogene-sis of VD.

BACKGROUND: Cervical spinal cord injury without radiographic abnormality (SCIWORA) is a special type of spinal cord injury. Because of the particularity of children in the period of growth and development on the aspects of anatomy and biomechanics, their injured mechanism and therapeutic method differ from those of adults.OBJECTIVE: To explore clinical feature and therapy of first-episode cervical SCIWORA in children.DESIGN: Retrospective analysis and self pre-and post-control observation.SETTING: Department of Spine Surgery, Second Affiliated Hospital,Harbin Medical University.PARTICIPANTS: Totally 14 patients with cervical SCIWORA, who were treated at the Departmentof Spine Surgery, Second Affiliated Hospital,Harbin Medical University between June 1997 and June 2003. Inclusive criteria: ①patients who had dysfunction of sensation, exercise and sphincter to different degree in clinic, ②patients who had no fracture dislocation after cervical vertebra X-ray plain film and MRI examination. The MRI examination showed the sign of spinal cord injury. T1WI spinal cord became thick. T2WI distributed at strip-shape high-signal region along spinal prosenchyma and spread upward and downward. There were 3 patients with complete spinal cord injury and 11 patients with incomplete spinal cord injury, among the patients with incomplete injury, there were 6 patients with central cord syndrome (CCS), 3 with Brown-Sequard syndrome and 2withfrontal spinal cord injury syndrome.METHODS: Retrospective analysis was performed in 14 children patients with cervical SCIWORA. Thirteen patients were not treated with operation and one patient was treated with cervical posterior atlantoaxial fusion. MAIN OUTCOME MEASURES: ASIA grading before and after treatment in patients.RESULTS: There were 1 dead patient and 13 cases with 3-year follow up averagely. Three patients were with insignificant amelioration, and others had recovery of limb function to different degree. According to ASIA grading standard, before treatment there were 3 cases in A grade, 5 cases in B grade, 5 cases in C grade and 1 case in D grade, and after treatment there were 1 case recovering to B grade, 2 cases to C grade, 5 cases to D grade and 2 cases to E grade.CONCLUSION: Restoration of neurofunction of children with cervical SCIWORA has closely correlation with degree of primary injury of spinal cord. Most of the patients were not treated with operation, and those with obviously instable cervical vertebra can be treated with operation.

BACKGROUND:The anatomic structures and kinetic characteristics are the bases to establish hand model, and the kinetic characteristics of hand are determined by the anatomic structure. So, numerous scholars have paid close attention to virtual hand models based on the anatomic structures of hand.OBJECTIVE: To construct visible hand model based on anatomic structure.DESIGN: Single sample trial.SETTING: Center Laboratory, Third Military Medical University of Chinese PLA.MATERIALS: This trial was carried out in the Center Laboratory, Third Military Medical University of Chinese PLA in October 2003. Two fresh adult hands, which involved wrist joint, provided by the Department of Anatomy, Third Military Medical University of Chinese PLA, were employed. The two hands had no organic damage by naked observation.METHODS: The specimens were embedded and mill-cut (mill-cut layer thinness 0.2 mm). Cannon (ESO 1OD) digital camera (6.3 million pixel) was used for image collection. Each image was 31.5 MB, Data of 1 200 images were obtained.Adobe Photoshop 7.0 software was used for image treatment and then two-dimensional cross-section images were collected. The bone, flexor tendon and the outline of hand was three-dimensionally reconstructed by using the software,which was developed by the Department of Computer Science and Technology,Tsinghua University and Institute of Computer Medicine, Department of Anatomy, Third Military Medical University of Chinese PLA.MATN OUTCOME MEASURES: Three-dimensional reconstruction of the bone, flexor tendon and outline of hand.RESULTS: ①The outline of hand: After being reconstructed, the outline, which consisted of all fingers and nails, was well displayed, and observed from many directions.② Three-dimensional reconstruction of the bone of hand: The reconstructed bones of hands involved digital bones, metacarpal bones, carpal bones and all joints, and they could be displayed solely or in groups with other reconstructed structures.③ Three-dimensional reconstruction of the flexor tendons of hand:Four superficial flexor tendons, four deep flexor tendons and one flexor pollex Iongus muscle tendon could be seen from the reconstructed images. All the flexor tendons went out together from the carpal canal and went through the palm, then spread out in fan-shape along the direction of each finger. ④ Three-dimensional reconstruction of the metacarpal fascial spaces: It could be observed from the reconstructed three-dimensional models that the proximal end of the thenar space was close, its distal end was open to the 1st web space, and the proximal end of the midpalmar fascial space was open to the posterior space of antebrachial flexor by carpal canal. Its distal end had three little spaces, which were open to the 2nd, 3rd and 4th web space, respectively.CONCLUSION: The visible hand model, which is preliminarily established, can precisely show the main anatomic structure of palm.

Objective To analyze the compliance and the influencing factors of the children with congenital hypothyroidism (CH).Methods 231 children with CH were collected for this study.The questionnaire survey and referring the case were used to collect relative factors.According to regular follow -up treatment,the children were divided into two groups,one group was good compliance and the other one was bad compliance.The results were ana-lyzed by two -independent sample t -test,2 -test and unconditioned logistic regression analysis.Results (1)Blood TSH(χ2 =59.870,P =0.00) and blood FT4 (χ2 =6.468,P =0.01) were normal,short distance from the hospital (χ2 =16.375,P =0.00),level of education of their mothers was high(χ2 =7.483,P =0.02),and regular compli-ance treatment of children with CH(χ2 =7.483,P =0.024) was good.(2) Logistic stepwise regression analysis showed that serum TSH value(OR =17.135),the short distance(OR =1.692) and diagnosis of CH(OR =4.028) were introduced into the logistic regression model (all P <0.05).Conclusion It is essential to take measures actively and reinforce the management of children with long distance,low -educated,and the diagnosis of TSH.More-over,enhancing the regular treatment compliance of children with CH is the key to improve the growth and develop-ment status of children with CH.

BACKGROUND: The treatment of upper cervical spine disorders through a posterior pedicle fixation approach have been carried out in some domestic large hospitals, but this surgery is still considered as a difficulty of cervical spine surgery. In order to minimize the risk of surgery, the authors designed a program of individual operations, and combined with self-developed pedicle locating and directing speculum to determine precise intraoperative position of pedicle screws, and no report is found by searching related database in China.OBJECTIVE: To improve the one-time success rate of internal fixation screws, to investigate the biomechanical effect of the implant, to formulate a simple, practical, individual protocol for atiantoaxial pedicle screw-plate system based on related data. METHODS: A total of 31 patients were recruited from Department of Orthopaedics in the 251 Hospital of Chinese PLA, between January 2002 and September 2006. Under the guidance of self-made atlantoaxial locating and directing speculum, the entrance point and angle for screw insertion, as well as screw diameter and length were determined according to the results of X-ray and CT measurement. Atlas pedicle screw was inserted at left (19.93±1.32) mm, and right (19.16±1.3) mm; Atlas pedicle screw insertion angle to inside was left (23.72±2.09)°, and right (23.35±1.91)°; Atlas pedicle screw insertion angle to side of head was (9.00±1.20)°. Axis pedicle screw was inserted at left (13.14±0.82) mm, and right (13.85±0.79) mm; Axis pedicle screw insertion angle to inside was left (24.52±1.26)°, and right (20.42±1.42)°; Axis pedicle screw insertion angle to side of head was (25.00±3.00)°.RESULTS AND CONCLUSION: ①Totally 124 pedicle screws were implanted into 31 patients, and 122 screws were of one-time success. The precision rate was 98.39%. Two screws were secondly inserted because of cutting lateral cortical bone of pedicle for deviation of inward angle. ②Occipital neuralgia was found in 2 cases postoperatively and cured after one month of treatment;screws penetrated atlas left vertebral lateral wall in 2 cases, no spinal or vertebral artery injury was found. ③Radiographs showed that atlas was completely reduced in all patients, and apposition of dentoid process of axis fracture was good. CT films showed the screws a good location to the vertebrarterial spinal cord. ④The follow-up visit was averaged of 10.5 months. Bony fusion was found in all patients. No screw-plate breakage was found. No inflammatory or rejection reactions occurred.⑤By JOA scale, there were 16 cases of excellent, 12 cases of good, 2 cases of fine, and 1 case of poor. The excellent and good rate was 90%. It is suggested that the success rate of atlantoaxial pedicle screw-plate mplantation can be improved through a biomechanical angle.

OBJECTIVETo observe the change of lipid metabolism and vascular endothelium as well as morphology of heart tissue in rats who were long-time exposed to moxa smoke with different concentrations in order to provide reference for safety assessment of moxa smoke on cardiovascular system.

METHODSOne hundred and sixty-eighty Wistar rats were randomly divided into a control group, a low-concentration group, a median-concentration group and a high-concentration group, 42 rats in each one. The rats were exposed to moxa smoke with concentration of 0%, 10%, 40% and 70%, respectively, for 20 min per day. After continuous intervention for six months, enzyme-linked immunosorbent assay (ELISA) was applied to measure the level of low density lipoprotein-receptor (LDL-r) and intercellular adhesion molecule-1 (ICAM-1) in blood serum in each group; the slices of heart tissue were stained with hematoxylin-eosin staining method to observe morphology change of heart tissue.

RESULTS(1) After the intervention of moxa smoke, the levels of LDL-r and ICAM-1 in the low-concentration group were not statistically different from those in the control group (both P > 0.05); the level of LDL-r in the median-concentration group was significantly increased, which was statistically different from that in the control group [(3.87 +/- 0.27) mg/mL vs (2.12 +/- 0.13) mg/mL, P < 0.01], however, the content of ICAM-1 was not obviously changed; although the level of LDL-r in the high-concentration group was presented with an escalating trend, it was not statistically different from that in the control group (P > 0.05) while the level of ICAM-1 was obviously increased (P < 0.01). (2) Under the light microscope, the abnormalities of cardiac muscle fibers and myocardial cell in each group were not been observed.

CONCLUSIONThe long-time intervention of low-concentration moxa smoke has no significant effects on lipid metabolism and vascular endothelium of rats, indicating that clinical application of low-concentration moxa smoke is relatively safe. The long-time intervention of moderate-concentration moxa smoke could significantly increase the clearance rate of cholesterol, implying the beneficial regulation of moxa smoke on lipid metabolism. The high-concentration moxa smoke could induce certain damage to vascular endothelium but its mechanism is in need of further research. The pathologic change of heart tissue could not be induced by moxa smoke with any concentration.

AIM: To investigate the expression of NKG2A,NKG2D and their ligands in pregnancy uterine micro-environment and to probe the function of NKG2A and NKG2D imbalance expression during the immunotolerance at the fetal-maternal boundary.METHODS: Decidual lymphocytes and peripheral lymphocytes were obtained from 30 women during 6-9 weeks of pregnancy who were undergoing selective termination.FACS technology was used to detect NK cells number and NKG2A,NKG2D expression.RT-PCR was used to investigate HLA-E and MICA mRNA in trophoblast tissue.RESULTS: Natural killer cells predominate,accounting for 70% of pregnancy endometrial lymphocytes.FACS results indicated that NKG2A was significantly increased in decidual NK cells as compared with that in peripheral NK cells,accounting for 97.86%?1.75% and 33.35%?10.92%.The difference between them in NKG2A expression was significant(P

Androgen insensitivity syndrome (AIS) is a very uncommon genetic disorder that results from the resistance of androgen receptor (AR) to androgen, which influences the formation of the male genitalia and in turn presents with female phenotype.Surgical resection of undesceaded testicle and different kinds of genitoplasty are crucial methods to correct the deformity of reproductive system, as well as hormone replacement therapy, which is an essential therapy for postoperational rehabilitation in AIS patients.A 43-year-old patient, who was socially female, was first admitted to gastroenterology department due to recurrent ascites and occasional abdominal pain with unknown origin.Taking physical examination, ultrasonography, karyotype analysis and sex hormone levels into consideration, the overall manifestations revealed the typical clinical features of complete androgen insensitivity syndrome.After that she was transferred to urology department for laparoscopic gonadectomy.During the surgery, doctors found that there was a vesical fistula on the upper wall near the conjunction between the bladder and ligamenta umbilicale medium, which explained the recurrent ascites for more than 4 years.After resecting the testicles and the tissues around the vesical fistula for histopathology, the result suggested Sertoli cell adenoma, hyperplastic Leydig cells and urothelium atypical hyperplasia.Hormone replacement therapy was given right after discharge.The hormone levels of follicle-stimulating hormone, luteinizing hormone, estradiol and progesterone were modulated by the dysfunction of androgen production after gonadectomy and hormone replacement therapy together with psychotherapy could stabilize her hormone levels and improve the quality of her life.The patient was suspicious of AIS family history and the pedigree was made to analyze her family which was possibly X-linked recessive pattern.We propose three possible hypotheses of the fistula, which are direct surgical injury, recurrence of bladder cancer and congenital urachal anomalies.But whether it is relevant between urachal anomalies and AIS is yet to be discovered.

A HPLC method was established to determine the contents of the five anthraquinones and rhaponticin in the different varieties of Rhei Radix et Rhizoma. The difference existed in different varieties. The results showed that rhein and rhaponticin were marker substances which could be used to distinguish palm leaf groups rhubarb and wave leaf groups rhubarb. Authentic rhubarb didn't contain rhaponticin. Falsify rhubarb contains trace amounts of rhein. Rheum tanguticum contains abundant rhein. The ratio value of the content of rhein to chrysophanol could be used to distinguish R. tanguticum from the other two authentic varieties (R. palmatum and R. officinale). The content of rhaponticin varied largely in different varieties of wave leaf groups rhubarb.
