Objective To search for the changes of T cells subpopulations and immunoglobulin and their relation-ship in children patients with simple nephrotic syndrome. Design Case-control research. Patients aud Participants 39 patients with simple nephrotic syndrome were divided into two groups:the incipient group and relapse group (6 cases were determined at the incipient and relapse time) .Thereare 28 patients in incipient group, 19 males and 9 females, at the age of 2 to 10 years old. There are20 patients in relapse group, 12 males and 8 females, at the age of 3 to 13 years old. There are 35health children in control group, 21 males and 14 females, 2～13 years old. Interventions T cells subpopulations were determined by indirect immunofluorescence of OKT linesmonoclonal antibodies. The serum IgG was determined by routine simple agar immunodiffusion tests. Results and Conclusions The CD_3~+ and CD_4~+ cells are of no change in the children patients withsimple nephrotic syndrome, and the CD_8~+ and CD_(10)~+ cells are obviously increased, the Values of CD_4~+/CD_8~+ are obviously lower than those in the control qroup, there are no difference between the incipientand relapse groups. The levels of serum IgG were decreased in the 85.3% children patients, IgM were inc-reased in 29.4% of that. The values of CD_4~+/CD_8~+ have positive correlation and negative correlationwith the levels of serum IgG and IgM respectively.

OBJECTIVE To investigate the HIV infections states in tumor patients for clinical diagnosis,treatment and to prevent HIV infection in the tumor hospital.METHODS The result of HIV detection in tumor patients from Dec 2000 to Aug 2006 was analyzed by the review statistics analysis.RESULTS Totally 48 101 tumor paients were detected,and the number of tumor patients with positive HIV antibody result was 51(0.106%).Among the positive patients there were 21 cases with blood transfusion history,14 cases with blood donating experience,2 cases with both these two kinds of experiences and 14 cases without the two kinds of experiences.Their rate was separately 41.0%,27.5%,4.0% and 27.5%.Most of the HIV positive patients had no clinical synptoms.CONCLUSIONS The HIV positive rate of patients with blood transfusion or blood donating is significantly higher than the patients without these experiences.The routine detection for the HIV before the operation,blood transfusion or other traumatic detection is very necessary.

Objective To identify mutations site and clinical characteristics of a familial hypercholesterolemia(FH) proband diagnosed clinically through DNA sequencing and family analysis in the proband and his family members of 3 generations.Methods Blood samples and clinical data of the kindred of total 29 from 3 generations members were collected.Proband had a physical examination electrocar-diogrom and vascular ultrasound.The proband and his family members took routine clinical exams,and genomic DNA was isolated.The promoter region and the 18 exons of low density liporotein receptor(LDLR) gene were screened by Touch down polymerase chain reaction -single strand conformation polymorphism(PCR-SSCP) and DNA sequencing.The result of sequencing were matched gene sequence published in the BLAST database.Results 1.Increased intima-media thickness and plaque were detected in the common carotid artery,right subclavian artery of the proband.Aortic valve regurgitation was found by echocardiography.2.No mutation R3500Q of ApoB100 was observed.3.Two heterozygous mutations in exon 10 and 13 of LDLR gene (W462X and A606T) were identified.The proband and 5 members of paternal relatives showed W462X heterozygosis mutation in exon 10 of LDLR gene which introduced the change from tryptophone to a new stop codon.The proband's mother and grandmother harboured A606T heterozygous mutation in exon 13 of LDLR gene due to a single base pair substitution of G for A in the codon for residue 1 879.Conclusions Disease causing mutations of proband are W462X and A606T compound heterozygosis mutation in exon 10 and 13 of LDLR gene inherited from mother and father.Proband shows homozyous phenotype though the genotype analysis indicates heterozygous mutations.

OBJECTIVEYoga is becoming more and more popular in the female society while the concomitant sports injury is seldom mentioned. Many clinicians have noted that yoga may result in knee problems, which though requires more researches to corroborate. This investigation was conducted to ascertain the relationship between yoga and meniscus injury as well as the extent of impairment according to variant yoga practice periods.

METHODSTotally 819 women aged 20-49 years who practiced yoga or other popular sports including badminton, jogging, climbing hills, etc for at least one hour per day were selected to participate in this research. These subjects were required to complete a questionnaire and receive relevant physical examination. Magnetic resonance (MR) scan of the knee was recommended for the suspicious subjects for ultimate diagnosis. The subject with abnormal meniscus MR signals was defined as a case and matched with two controls in terms of age and body mass index (BMI). Altogether there were 273 cases and 546 controls. The nested case-control model was adopted to assess the risk of meniscus injury between variant exposures in practicing yoga and several other popular sports. Moreover, the 181 yoga subjects were subdivided into three groups according to different exercise durations, followed by further analysis with the variables of age, BMI and Lysholm score.

RESULTSYoga was found associated with a higher risk (P equal to 0.008, OR equal to 1.621) of meniscus injury compared with badminton, jogging and climbing hills. The three yoga subgroups showed statistical difference between each other in terms of Lysholm score (P equal to 0.027) and BMI (P equal to 0.003). The subjects with longer-term yoga practice had lighter weight but lower Lysholm scores.

CONCLUSIONSYoga perhaps exerts destructive impact on the meniscus for Chinese women, yet it needs further verifications. Furthermore, the female yoga players with longer exercise duration are more susceptible to meniscus injury though they can become leaner.

OBJECTIVETo evaluate the clinical efficacy of a combined in-office cold light bleaching and night-guard vital bleaching (NGVB) system for treating tetracycline stained teeth (TST).

METHODS90 patients with light, medium and heavy TST were randomly and evenly divided into 3 groups. 30 patients with 472 TST from the treatment group were treated with in-office cold light bleaching and NGVB, 30 patients with 466 TST from the control group 1 were treated with in-office cold light bleaching and 30 patients with 469 TST from control group 2 were treated with NGVB. At the time of treatment completion, after half a year and after one year, Vitalescence esthetic restorative masters shade guide was used to record the change of color. Bleaching efficacy and course of treatment were calculated, and lightening stability were evaluated.

RESULTS1) Three groups had satisfied lightening efficacy for light TST with 100% bleaching efficacy. The overall efficacy of treatment group and control group 2 were superior to the in-office cold light bleaching system (P < 0.05). Though there was no significant lightening efficacy difference between the treatment group and control group 2 (P > 0.05), the periods of treatment of the treatment group for light, medium and heavy TST were shortened by 43%, 46% and 49%, respectively, compared to the control group 2. 2) All three groups' treatment efficacy for light, medium and heavy TST became weaker progressively (P < 0.05). 3) For the treatment efficacy between the time of treatment completion and after half a year and one year, there was significant statistical difference (P < 0.01) for the control group 1, while there was no significant difference for both the treatment group and the control group 2 (P > 0.05). Both treatment group and control group 2 had better performance in treatment stability than control group 1.

CONCLUSIONIn treating the light and medium tetracycline stained teeth, the combined in-office cold light bleaching and NGVB system can achieve a more satisfied whitening result in much shorter period, and significantly enhance the long term whitening stability.

OBJECTIVETo compare the differences in the clinical function and lumbar and abdominal myodynamia in patiants of lumbar disc herniation treated with moxibustion at Dazhui (GV 14) and Guanyuan (CV 4) and acupuncture.

METHODSForty cases were randomized into a moxibustion group and an acupuncture group, 20 cases in each group. In the moxibustion group, the warm moxibustion was applied alternatively at Dazhui (GV 14) and Guanyuan (CV 4) once every other day, 1 h each time, once every day. In the acupuncture group, acupuncture was applied to the corresponding acupoints based on the affected lumbar vertebras, such as Jiaji (EX-B 2), Shens-hu (BL 23), Dachangshu (BL 25) and Huantiao (GB 30), etc. , once evey day 30 min each time. The treatment for 3 weeks was taken as one session in each group. Totally, one session treatment was required. Surface electromyography (SEMG) of bilateral paraspinal muscle and rectus muscle, and JOA score of low back pain were observed in the two groups.

RESULTS(1) JOA score: the score of subjective symptoms, score of activity of daily living (ADL) and total score were improved obviously as compared with those before treatment in the two groups (P<0.01, P<0.05). The results of subjective symptoms score, score of ADL and total score in the acupuncture group were superior to those in the moxibustion group after treatment (6.95+/-0.94 vs 5.50 +/-0.89,10. 90+/-1.86 vs 8.90+/- 1. 92,22.50 +/- 2.82 vs 19.35 +/- 2. 70, all P<0. 05). (2) SEMG comparison: root-mean-square value (RMS) was all reduced in SEMG of the anteflexion, rear protraction, orthostatism, bilateral bending and neck and leg rear flexion for strengthening lumbar muscle as compared with those before treatment in the two groups (P< 0.05, P<0. 01). RMS of the anteflexion and bilateral bending in the acupunture group were reduced much obviously as compared with the moxibustion group. In terms of sitting position anteflexion, rear protraction, orthostatism, bilateral bending and neck and leg rear flexion for strengthening lumbar muscle, median frequency (MF) after treatment was all improved as compared with that before treatment in the two groups (P<0. 05, P<0. 01). In terms of anteflexion, the electrode MF after treatment was improved much obviously in the acupuncture group(P<0. 05).

CONCLUSIONMoxibustion at Dazhui (GV 14) and Guanyuan (CV 4) and conventional acupuncture all improve muscle function, relieve muscle fatigue, increase the ability of anti-muscle fatigue, strengthen lumbar vertebral stability, release subjective symptoms and improve ADL. But, the effects of moxibustion are slightly lower than those of acupuncture.

OBJECTIVETo study the relationship between levels of serum HA, LN, IV-C, PC III of chronic hepatitis and indexes of hepatic fibrosis.

METHODSThe levels of serum HA, LN, IV-C and PC III of chronic hepatitis of 124 cases and health 18 cases were measured by radio immunoassay, combined with clinical characteristics and 33 cases pathologic slice etc. The diagnostic of the indexes of serum was analyzed with statistics.

RESULTSHA and IV-C are parallel in chronic hepatitis periods. LN and PC III are concert in the same pathologic periods. In G4 period PC III is nearly closed with comparative group. The value of HA, LN, NV-C and PC III in the chronic hepatitis group was significantly higher than that in the normal comparative group. Conclusion The levels of serum HA LN IV-C and PC III are in concert with the degree of hepatic fibrosis, and these indexes are valuable for chronic hepatitis diagnoses combined with the clinic. LN and PC III are coincidence with hepatic fibrosis degree before G4 period.

Objective To investigate the effects of advanced glycation end-products(AGEPs)on the function of normal keratinocytes in vitro so as to explore the role of AGEPs in impaired wound healing. Methods Normal rat keratinocytes were incubated with different concentrations of AGEPs.After 48 hours of culturing,the cell proliferation rates were measured by MTT colorimetric determination.The cell cycle distributions and apoptosis were analyzed with flow cytometry,and the migration was investigated by 24-well fluorimetric cell migration assay kit by exposing to 100?g/ml AGEPs.Nuclear extracts from these cells were examined for binding of nucleotides containing NF-?B consensus by immunocytochemistry and EMSA in vitro.Results The proliferations of normal keratinocytes were significantly arrested and many cells were induced to early apoptosis compared with control ones(P＜0.05)by exposing to AGEPs for 48 hours. Meanwhile AGEPs also irritated keratinocytes migration compared with control ones(P＜0.05).Inhibiting the activation of NF-?B could partly recover the proliferation of keratinocytes,reverse apoptosis and attenu- ate migration.Conclusion AGEPs are correlated with the migration,proliferation and apoptosis of kera- tinocytes by NF-?B.

OBJECTIVETo probe into the clinical effect of needle-pricking therapy for treatment of polycystic ovarial syndrome.

METHODSOne hondred and twenty-one cases of polycystic ovarial syndrome were divided into a needle-pricking therapy group of 61 cases and a medication group of 60 cases with randomized and controlled method. The needle-pricking therapy group were treated by needle-pricking therapy at sacral plexus stimulating points on both sides of the spine and lateral points of Dazhui (CV 14), and the medication group by oral administration of domiphen and intramuscular injection of chorionic gonadotropin (HCG). Levels of hormones and symptoms in the patients before treatment, after treatment of 3 cycles and at the sixth cycle after treatment were investigated.

RESULTSAfter treatment of 3 cycles, the level of hormone and B type ultrasound examination were significantly improved in the two groups (P < 0.01). At the sixth cycle after treatment, the conditions of the patients in the medication group were returned to the original levels before treatment, while the conditions in the needle-pricking therapy group still kept at the post-therapeutic level, and their menstruation and ovulation restored to normal state, and the ovulation mucosa and the pregnancy rate were significantly higher than those in the medication group (all P < 0.01).

CONCLUSIONNeedle-pricking therapy has obvious effect on polycystic ovarial syndrome, and has a good long-term therapeutic effect.
