OBJECTIVETo explore effect of Qindan Fuzheng Capsule (QFC) on ultrastructure of cardiomyocytes and hepatocytes injured by high microwave radiation in rats.

METHODSEighteen adult Wistar rats were equally divided into 3 groups in random: rats in Group A were untreated as the normal control, rats in Group B received 6 min microwave radiation (100 mW/cm2 high power) to cause injury of cardiomyocytes and hepatocytes, and Group C received the same radiation but treated with QFC perfusion, 2 mL (equivalent to 4.75 g crude drug) once a day, for 7 successive days, starting from 6 h after radiation. All rats were sacrificed 7 days later, their fresh tissue of heart apex and right lobe of liver were taken and prepared to routine transmission electron microscopy specimen for ultrastructural observation.

RESULTSCompared with Group A, different degrees of ultrastructural changes on nuclei and organelle were observed in Group B and C, but the injury in Group C was significantly milder than that in Group B, showing normal sized cells with good structure approximate to the morphology in Group A.

CONCLUSIONSQFC showed protective effect on microwave radiation injured ultrastructural changes in rats' cardiomyocytes and hepatocyte. Its mechanism was possibly correlated with the suppression of lipid peroxidation and the improvement of metabolism in myocardial and hepatic cells.

Objective To explore the causes and treatment of repeated vulvovaginitis in girlhood in order to improve its prevention and treatment.Methods Fifty-one girls with repeated vulvovaginitis(age≤10 years)admitted to The Second Affiliated Hospital of Sun Yat-sen University from Jan.1990 to Nov.2004 were reviewed retrospectively.Results We found 28 girls(55%)suffering from non-specific vulvovaginitis and 14 ones(27%)suffering from posterior recto-vaginal fistula with in 51 patients.Five girls(10%)were smitten with vulval ulcer and 3 ones(6%)had been were found with vaginal foreign bodies.One girl(2%) was smitten with adhesion of labia minora.The vaginal discharges taken from 21 girls were cultured. Seventeen cases found bacteria.The positive rate of bacteria culture in the 21 cases reached 81%,in which, E.coli accounted for 5 cases(24%),staphylococcus and streptococcus accounted for 3 cases(14%) respectively.Patients suffered from non-specific vulvovaginitis and vulval ulcer accepted external lotion, antibiotic ointment or combining with antibiotics.Patients suffered from posterior recto-vaginal fistula accepted fistulectomy.Three girls who found vaginal foreign bodies took out of foreign bodies by hysteroscopo.Fifty-one girls all were cured after appropriate therapy.Conclusions Vulvovaginitis is the most common gynecologic diagnosis in girlhood.The principal cause of repeated invasion is non-specific vulvovaginitis and the secondly one is posterior recto-vaginal fistula.It need overhaul during the diagnosis.It is very availability to use hysteroscopy and do bacteria culture+antibiotic sensitivity test for repeated pediatric vulvovaginitis.

AIM: To better reveal the changing process of macula area after photodynamic therapy (PDT), the changes of tomographic imaging on macular fovea optical coherence tomography ( OCT ) scan at different follow- up time points after treating age-related macular degeneration ( AMD) by PDT were investigated.
METHODS: This cohort study included 30 eyes of 26 patients diagnosed as AMD. The dosage of verteporfin was calculated according to manufacturer's instruction. All participants got FFA, ICG, OCT scan and best corrected visual acuity before and followed up for 2wk, 1, 2, 3mo after PDT. The standard five lines combined with 6 lines OCT scan covered key parts of lesion and the scan locations before and after were kept the same. The bilaminar foveal thickness (BFT), outer high reflectivity band thickness ( OHRBT ) , and the total area of intraretinal fluid ( IRF ) and subretinal fluid ( SRF ) were measured at different time points. The relationship between the changes and follow up time was analyzed. Statistical analysis of the data was performed using SPSS for windows version 13. 0.
RESULTS: There months after treatment, an improvement of 2 lines or better on the Snellen chart was achieved on 22 eyes, visual acuity of 3 eyes without significant change, 3 eyes got decreased, 2 cases lost follow up. The average macular thickness of improved 22 eyes before treatment was 722. 5±55. 6μm, 2wk after treatment, 708. 3±45. 3μm, 1mo, 584. 4±49. 3μm, 2mo, 430. 7±50. 2μm and 180. 6 ±36. 3μm at 3mo. The OHRBT before and after treatment respectively were 302. 3 ±50-2μm, 277. 5±42. 3μm, 202. 7±40. 1μm, 180. 6±35. 7μm, 100. 8±22. 9μm.

Objective To explore the effects of modified tubo-uterine implantations performed on women with proximal tubal occlusive infertility after femal sterilization with mucilago phenol.Methods Two hundred and eight infertile women who were admitted to the Second Affiliated Hospital of Sun Yat-sen University between 1986 and 2004 were included.They all accepted modified tubo-uterine implantation after occlusion of fallopian tubes with mucilago phenol.Results It was found that the occlusions were all located in the interstitial portion or isthmic portion of the fallopian tubes.Different degrees of pelvic adhesions were found in 65 cases.Fifty-seven cases were slightly adhesive,seven cases were of moderate degree and one case was severe.One hundred and ninety-nine cases were followed up after operations(95.7%).One hundred and ninety-three women accepted hydrotubation in the following month just after the operation and 185 women were found to be unobstructed(95.8%).One hundred and forty-three women became pregnant, the pregnant rate being 71.9%(143/199).One hundred and twenty-five women had term deliveries (87.4%),three women were in early pregnancy and two in midtrimester pregnancy.Eleven women had spontaneous abortion(7.7%).Two women had tubal pregnancy(1.0%).None of the 199 cases had any signs of endometriosis.Conelusions Modified tubo-uterine implantations are quite effective for proximal tubal occlusive infertility.It may be a favorable method for such kind of tubal occlusions.

OBJECTIVETo study the effect of Sanhuang Jiangtang recipe (SJR) on renin-angiotensin system in local myocardium in diabetic rats.

METHODSRats were made into diabetes model by intraperitoneally administering of streptozocin, and medicated through gastrogavage with SJR (50 g/kg), gliclazide (20 mg/kg), captopril (15 mg/kg) and nitrendipine (30 mg/kg) respectively, for successive 8 weeks, started from 2 weeks after modeling. Levels of fasting blood sugar (FBS), serum insulin (Ins), heart/body weight ratio (H/BW), myocardial angiotensin II (Ang II), angiotensin converting enzyme (ACE) and aldosterone (ALD) were determined. And the mRNA expression of type I angiotensin receptor (AT1R) in myocardium were detected by RT-PCR assay.

RESULTSAs compared with those in the normal rats, levels of FBS, H/BW, Ang II, ACE, ALD and AT1R mRNA expression were higher (all P < 0.05) and level of serum Ins was lower (P < 0.01) in the model rats. SJR, gliclazide, captopril and nitrendipine could slightly reduce the blood sugar level in model rats, but with no increase of serum Ins. All the four drugs could reduce H/BW, Ang II, ACE and AT1R mRNA expression. SJR and captopril could also decrease the ALD content in myocardium.

CONCLUSIONCardiac hypertrophy has been induced in 10 weeks after diabetic modeling. Activation of local myocardial RAS is related to the genesis of diabetic cardiomyopathy. SJR, gliclazide, captopril and nitrendipine could antagonize the genesis of diabetic cardiomyopathy, the mechanism is related to the inhibition of RAS activation in local myocardium.

OBJECTIVETo compare the clinical efficacy in the treatment of allergic rhinitis (AR) of lung qi deficiency and cold syndrome between Jin's three-needle therapy and western medication.

METHODSSixty-six patients were randomized into an acupuncture group and a western medication group, 33 cases in each one. In the acupuncture group, acupuncture was applied at three-nose points [Yingxiang (LI 20), Shangyingxiang (EX-HN 8) and Yintang (GV 29); Cuanzhu (BL 2) was added for frontal headache] and three-back points [Dazhu (BL 11), Fengmen (BL 12) and Feishu (BL 13)], once every day. Ten treatments made one session. Two sessions of treatment were required. In the western medication group, desloratadine oral suspension was prescribed, 5 mg each time, once a day, for 20 days. The scores of the symptoms and physical signs in AR patients as well as the clinical efficacy were observed between the two groups.

RESULTSThe total effective rate was 93.9% (31/33) in the acupuncture group, which was better than 72.7% (24/33) in the western medication group (P < 0.05). After treatment, the scores of AR symptoms and physical signs as well as the total score were all reduced compared with those before treatment in the two groups (all P < 0.01). The score of every item in the acupuncture group was lower than that in the western medication group after treatment (score of symptoms: 4.70 +/- 2.07 vs 6.55 +/- 2. 69, score of physical signs: 0.85 +/- 0.67 vs 1.45 +/- +0.62, total score: 5.36 +/- 2.70 vs 8.00 +/- 2.91, all P < 0.01).

CONCLUSIONJin's three-needle therapy achieves superior efficacy on AR of lung-qi deficiency and cold syndrome, which is better than desloratadine oral suspension.

OBJECTIVETo investigate the effect of Inonotus obliquus polysaccharides on testicular injury induced by exposure to high power microwave (HPM) in rats.

METHODSA total of 30 male Wistar rats were randomly divided into 5 groups, i.e., the normal control group, the microwave radiation model group, the treatment group, the new microwave radiation model group, and the prevention group, 6 in each group. All rats, except those in the normal control group, were exposed to microwave at an average power density of 200 mW/cm2 for 6 min. Rats in the control group and the model group were administered with normal saline by gastrogavage, once a day. Rats in the treatment group and the prevention group were given with Inonotus obliquus polysaccharides by gastrogavage, 2 mL each time (400 mg/kg body weight), once a day. All rats were sacrificed on the 11th day.The sperm density and the rate of sperm deformity were determined. Pathological changes of testis were observed by light microscope and transmission electron microscope.

RESULTSShort-term HPM irradiation could significantly reduce the sperm density and increase the sperm deformity rate (P < 0.05). Meanwhile, obvious pathological changes of testes occurred. Compared with the two model groups, the sperm density increased and the sperm deformity rate decreased in the treatment group and the prevention group (P < 0.05). Under the light microscope, injuries of spermatogenic cells and stromal cells, as well as vascular dilatation and congestion were obviously alleviated in the treatment group and the prevention group. Mitochondrial swelling and endoplasmic reticulum expansion shown by ultrastructural observation were also significantly alleviated. Of them, injuries of spermatogenic cells and inflammation response were milder in the treatment group than in the prevention group.

CONCLUSIONSInonotus obliquus polysaccharides had significant protective effect on microwave radiation induced testicular injury. Better effect was obtained by therapeutic medication than preventive medication.

OBJECTIVETo investigate the expressions of vinculin (VCL) and the androgen receptor (AR) in benign prostatic hyperplasia (BPH) and prostate cancer (PCa) and analyze their relationship with the clinical stage and pathological grade of PCa and the level of PSA.

METHODSWe detected the expressions of VCL and AR in 18 cases of BPH and 38 cases of PCa by immunohistochemistry, analyzed the differences of VCL and AR expressions in BPH and PCa in different clinical stages and pathological grades of PCa, compared the primary levels of PSA, and studied their correlations.

RESULTSThe positive rate of VCL was significantly higher in PCa than in BPH tissues (P < 0.05), while that of AR showed no significant differences between the two groups (P > 0.05). Both the expressions of VCL and AR were closely related with the clinical stage and pathological grade of PCa (P < 0.05), but not with the PSA level (P > 0.05). There was a positive correlation between the expressions of VCL and AR in PCa tissues (r = 0.489, P < 0.05).

CONCLUSIONVCL is expressed differently in BPH and PCa, which may serve as an indicator for the differential diagnosis of benign and malignant prostate diseases. The expressions of AR and VCL are gradually reduced with the progression of PCa, with a positive correlation between them, and could be used jointly to evaluate the progression and prognosis of PCa.

OBJECTIVETo explore the anti-tumor immunity in vitro induced by prostate cancer cell vaccine transfected with recombinant adenovirus encoding 4-1BBL in mice.

METHODSThe replication-deficient adenovirus AdEasy-1 system was used to construct recombinant adenovirus Ad-m4-1BBL and Ad-eGFP. The prostate cancer cell RM-1 of mice was transfected with Ad-m4-1BBL and Ad-eGFP, and treated with mitomycin (MMC) to produce TCV, TCV-Ad-eGFP and TCV-Ad-m4-1BBL, followed by co-culture with syngeneic murine spleen cells. Then the cytotoxic activity of the lymphocytes against RM-1 cells was analyzed with CCK-8 solution, and IL-2 and INF-gamma were detected by ELISA.

RESULTSThe 4-1BBL protein was highly expressed in the TCV-Ad-m4-1BBL of the 4-1BBL-transfected mice. TCV-Ad-m4-1BBL significantly increased the expressions of IL-2 ([180.24 +/- 2.22] pg/ml) and INF-gamma ([1512.46 +/- 23.64] pg/ml) as compared with TCV and TCV-Ad-eGFP (P < 0.05), and induced higher RM-1 cell specific cytotoxicity ([34.24 +/- 2.64]%) than the latter two ([9.82 +/- 1.48]%) and ([14.65 +/- 3. 21]%), (P < 0.05). But none of them exhibited significant cytotoxicity against hepatocellular carcinoma Hepal-6.

CONCLUSIONThe m4-1BBL-expressing prostate cancer cell vaccine can effectively induce anti-tumor immune responses.
