Objective To explore the expression and mutual relationship between transforming growth factor-?(TGF-?) and hepatocyte growth factor(HGF) in children's renal tissues,as well as the effect of the 2 indexes on the renal pathological change.Methods According to the severity of renal pathological change under light microscope,61 cases were divided into 3 groups:named control group(26 cases,clinically diagnosed as thin basement membrane nephropathy),test group Ⅰ [22 cases,clinically diagnosed as less evident focal segmental glomerulosclerosi(FSGS) nephropathy] and test group Ⅱ(13 cases,clinically diagnosed as evident FSGS nephropathy).Immunity class test(SP method:streptavidinbiotin peroxidase method) was used to detect the representation of HGF and TGF-?.Semi-quantitative analysis had been carried out in all cases.Film reading of cell was viewed by Olympus microscope,brown yellow from cytoplase as the positive signal,10 high power microscope visions were randomly selected from renal glomerali area and 10 from renal interstitium area.Medical image analysis software was used to determine the masculine area of HGF or TGF-? and image intensity;then the immunity class index was defined as masculine area ? image intensity.Results 1.HGF and TGF-? existed in all renal tissues;2.Expressions of HGF and TGF-? increased obviously along with FSGS pathology alteration(Pa

AIMTo study the endogenous mechanism for the inhibition of aquaporin-1 expression in rat renal proximal tubule epithelial cells in response to acetazolamide.

METHODSPrimary cultured rat renal proximal tubule epithelia cells were divided into two groups: one was subjected to 1 x 10(-5) mol.L-1 acetazolamide, the other served as normal control. When grown to sub-confluency, the cells were disintegrated to perform isoelectrofocusing electrophoresis in order to find the differential proteins induced by the acetazolamide treatment. The differential proteins were defined by peptide mass fingerprinting technology.

RESULTSTwo differential proteins were found in the cell disintegrant. The pI 3.8 protein was reduced after treatment, which showed 21.4% similarity with the brush border membrane myosin from rat brain and testis, and 27% with glycogen phosphorylase; The pI 5.5 protein was increased on the contrary, with 20% similarity to phosphatidylinositol transfer protein alpha isoform.

CONCLUSIONAcetazolamide inhibited AQP1 expression probably by affecting the expression of pI 3.8 and pI 5.5 proteins.

OBJECTIVETo study clinical effects of one-hole microplate internal fixation for the treatment of collateral ligament injuries of the metacarpophalangeal joint of the thumb combined with fracture.

METHODSTwenty-two patients (16 males, 6 females) with collateral ligament injuries of the metacarpophalangeal joint of the thumb combined fracture were treated with one-hole microplate internal fixation. The age of the patients ranged from 18 to 53 years old with a mean age of 28.5 years old. The duration from injury to surgery ranged from 2 hours to 2 months, and the mean time was 6 days. All the patients had collateral ligament injuries combined with fracture of the metacarpophalangeal joint of the thumb. Thirteen patients had injuries in the right hand and 9 patients had injuries in the left hand. There were 18 cases of closed wound and 4 cases of open wound. Eighteen patients had fresh injuries (< 2 weeks) and 4 had old injuries (> 2 weeks). Sixteen patients had injuries in the ulnar collateral ligament of the thumb combined with fracture, 6 patients had radial collateral ligament injuries of the thumb combined with fracture, 4 cases of which were complicated with injuries of abductor pollicis brevis and the end of the flexor pollicis brevis tender. The size of the avulsed fragment was about 3.0 mm x 4.0 mm to 6.0 mm x 7.0 mm.

RESULTSThe incisions of 22 patients healed by first intention. The follow-up periods ranged from 6 months to 5 years old,with an average of 2.5 years old. The thumb function was evaluated by Saetta and other evaluation criteria, and 20 patients got an excellent result and 2 good.

CONCLUSIONThe application of one-hole microplate internal fixation in treating collateral ligament injuries with fracture of the metacarpophalangeal joint of the thumb is an effective method.

In order to clarify the chemical constituents in Qiliqiangxin capsule, a rapid ultra-performance liquid chromatography/orthogonal acceleration time-of-flight mass spectrometry (UPLC-Q-TOF/MS(E)) method was established. Forty peaks were identified on line using this method. The herbal sources of these peaks were assigned. The results implied that triterpenoid saponins, flavonoid glycosides, C21-steroids and phenolic acids were included in the main components of Qiliqiangxin capsule. The method is simple and rapid for elucidation of the constituents of Qiliqiangxin capsule and the results are useful for the quality control of Qiliqiangxin capsule.

OBJECTIVETo investigate the correlation of prolactin receptor (PRL-R) expression to estrogen receptor (ER) and progesterone receptor (PR) expressions in primary breast cancer.

METHODSFor 130 female patients with breast cancer (median age 46 years), PRL-R expression in the primary tumor was detected by immunohistochemistry, and the correlation between PRL-R and ER/PR expressions was analyzed statistically.

RESULTSPRL-R positivity in the primary tumor was found in 89 of the patients (68.5%), and the positivity rate for PRL-R was positively correlated to ER expression (P<0.05). Further stratification of the patients according to the CerbB-2 status revealed such a correlation only in CerbB-2-positive patients (P<0.05). In the patient cohort, no significant correlation was found in the positivity rate between PRL-R and PR expressions (P>0.05), but in CerbB-2-positive patients, the positivity rate of PRL-R showed a positive correlation to PR expression (P<0.05).

CONCLUSIONThe positive correlations in positivity rate between the PRL-R and ER/PR expressions are found only in CerbB-2 positive patients with breast cancer, and the expressional status of CerbB-2 affects the correlation between PRL-R and ER/PR expression in breast cancer.

Objective To investigate the effects of ω-3 polyunsaturated fatty acid(PUFA)on oxidative stress produc-tion and apoptosis in hippocampus of neonatal rats with brain injury induced by lipopolysaccharide(LPS). Methods Forty-eight neonatal Sprague Dawley rats(3 days)were randomly divided into control group,LPS group,ω-3 PUFA group and ω-6 PUFA group,with 12 rats in each group. The rats in the LPS group,ω-3 PUFA group and ω-6 PUFA group were given 0. 6 mg·kg - 1 LPS via intraperitoneal injection,then equal volume of saline,ω-3 PUFA and ω-6 PUFA was immediately given via intraperitoneal injection respectively;while the rats in the control group were all given equal volume of saline. The rats in each group were sacrificed at 24 hours after intraperitoneal injection with saline or fat emulsions to obtain the hippocampus. The levels of superoxide dismutase(SOD)and malondialdehyde(MDA),reduced glutathion(GSH),oxidized glutathione(GSSG) were detected and GSSG/ GSH was calculated. The apoptotic index was measured by terminal deoxynucleotidyl transferase-me-diated dUTP nick end labeling. Results Compared with the control group,the levels of SOD and GSH in hippocampus of rats in the LPS group,ω-6 PUFA group and ω-3 PUFA group were significantly decreased(P < 0. 05),and the levels of MDA, GSSG and the ratio of GSSG/ GSH were significantly increased(P < 0. 05). Compared with the LPS group,the levels of SOD and GSH in hippocampus of rats in ω-6 PUFA group were significantly decreased(P < 0. 05),the levels of MDA,GSSG and the ratio of GSSG/ GSH were significantly increased(P < 0. 05);the levels of SOD and GSH in hippocampus of rats in ω-3 PU-FA group were significantly increased(P < 0. 05),the levels of MDA,GSSG and the ratio of GSSG/ GSH were significantly de-creased(P < 0. 05). Compared with the ω-6 PUFA group,the levels of SOD and GSH in hippocampus of rats in ω-3 PUFA group were significantly decreased(P < 0. 05),the levels of MDA,GSSG and the ratio of GSSG/ GSH were significantly in-creased(P < 0. 05). The apoptotic index in the LPS group,ω-6 PUFA group and ω-3 PUFA group was higher than that in the control group(P < 0. 05). The apoptotic index in the ω-6 PUFA group was higher than that in the LPS group(P < 0. 05). The apoptotic index in the ω-3 PUFA group was lower than that in the LPS group and ω-6 PUFA group(P < 0. 05). Conclusion ω-3 PUFA can alleviate the oxidative stress,and decrease the apoptosis of hippocampus in neonatal rats with brain injury in-duced by LPS. So it has a neuroprotective effect in brain injury induced by LPS.

OBJECTIVE: To observe the correlation between referred pain distribution and acupoint sensitization in patients with intestinal diseases. METHODS: In clinical research, 443 patients from 8 hospitals were recruited, including the outpatients and inpatients of Crohn's disease (=143), ulcerative colitis (=108), chronic appendicitis (=87) and other intestinal diseases (=105). The site with tenderness on the body surface and the morphological changes of local skin were observed and recorded in the patients. Using a sensory tenderness instrument, the pain threshold at the sensitization point was measured in 60 patients with ulcerative colitis. In animal experiment, SD rats were used and divided into a enteritis group (=8), in which the enteritis model were established, and a control group (=3), in which no any intervention was given. After the injection of Evans blue (EB) at caudal vein, the blue exudation points on the body surface were observed and the distribution rule was analyzed statistically. RESULTS: The referred pain on the body surface in the patients with intestinal diseases was mainly located in the lower abdomen (93.9%, 416/443), the lumbar region (70.9%, 314/443) and the lower legs (33.0%, 146/443). The diameter of tenderness region was 1.5 to 2.5 cm. Compared with the region without sensitization, the pain threshold of the sensitization point in the patients with ulcerative colitis was reduced significantly (<0.001). The referred pain on the body surface in the patients with appendicitis was located in the right lower abdomen (97.7%, 85/87), the waist and back (54.0%, 47/87) and the right lower limbs on the medial side (71.3%, 62/87). The tenderness region was 1 to 2 cm in diameter and was irregular in form. After modeling of enteritis in the rats, the EB exudation points were visible from T to L. CONCLUSION Intestinal diseases induce referred pain on the body surface where is the same as or adjacent to the location of the spinal segment corresponding to the affected intestinal section. These sensitization regions are related to the locations of acupoints.
