Objective To observe the effect of microprismatic needle scalpel(MPNS) on headache induced by compression of greater occipital nerve or lesser occipital nerve.Methods 95 patients with headache induced by compression of occipital nerve were divided into the treatment group (50 cases, treated with MPNS) and control group (45 cases, treated with carbamazepine).Results In the treatment group, 42 cases were cured, 6 cases were effective, 2 cases were ineffective; while, those in the control group were 16 cases, 21 cases and 8 cases respectively. There was a significant difference between two groups ( P<0.01).Conclusion MPNS has an obvious effect on headache induced by compression of occipital nerves.

OBJECTIVETo explore the association of 8-hydroxyguanine glycosidase OGG1 Ser326Cys polymorphism with semen quality and the risk of male infertility.

METHODSThis case-control study included 620 idiopathic infertile patients and 385 normal fertile controls. We determined their genotypes by polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP) and analyzed their semen quality by computer-aided semen analysis (CASA).

RESULTSThe individuals with OGG1 326 Cys/Cys showed significantly lower sperm motility and concentration ([52.1 +/- 26.7]% and (3.75 +/- 0.91) x 10(6)/ml, ln transformed value) than the Ser/Ser carriers ([59.0 +/- 21.8] % and (4.12 +/- 0.88) x 10(6)/ml, ln transformed value) (P < 0.05). The risk of male infertility increased 69% in the OGG1 326Cys allele carriers as compared with the Ser carriers (OR = 1.69, 95% CI: 1.24 -2.31).

CONCLUSIONOGG1 326 Ser/Cys polymorphism might contribute to the risk of male infertility in the southern Chinese population.

OBJECTIVETo observe the association between angiotensin-converting enzyme (ACE) gene polymorphism and endothelial nitric oxide synthase (eNOS) gene polymorphism and risk of coronary artery disease (CAD) in Han Chinese.

METHODSThe polymorphism in the ACE and eNOS gene were detected by using polymerase chain reaction-restriction fragment length polymorphism analysis, blood pressure (BP), blood lipids, blood glucose (BS), body mass index (BMI) and left ventricle eject fraction (LVEF) were determined 236 patients with CAD and 190 healthy individuals.

RESULTSThe frequencies of DD genotype of ACE were higher and the II genotype were lower in CAD patients than in controls (P < 0.05). CAD patients with DD genotypes were related with higher serum TG, lower HDL-C, higher BS levels, higher BWI and lower LVEF compared to CAD patients with II and ID genotypes of ACE (all P < 0.05), while SBP, DBP, TC and LDL-C levels were similar among CAD patients and controls with different genotypes of ACE (P > 0.05). The genotype distributions of ACE and eNOS were also similar among CAD patients with or without diabetes mellitus/ACS, with single or multiple vessel diseases (P > 0.05). The frequency of GT genotype of eNOS was higher in CAD patients than in controls (P < 0.01) while the frequency of GG genotype in CAD patients and controls was similar (P > 0.05) and eNOS genotypes were not related to TC, TG, HDL-C, LDL-C, BS, BMI, SBP, DBP and LVEF levels among CAD patients and controls (P > 0.05). The risk of suffering from CAD in population with ACE DD genotype is 1.74 times higher than that with II genotype (P < 0.01) and 1.73 times higher in population with eNOS GT genotype than that with GT genotype (P < 0.05). The risk of suffering from CAD is 37.9% with II and GG genotypes and 77.8% with DD and GT genotypes.

CONCLUSIONThe ACE and eNOS genotype polymorphisms were associated with risk of CAD and persons with DD and GT genotypes take higher risk of suffering from CAD.

BACKGROUNDOne stage transanal Soave pull-through procedure (TSPP) is a recent popular operation in the treatment of Hirschsprung's disease (HD). With no visible scar and a short hospital stay, it is well accepted by surgeons and mothers. In the conventional Soave procedure, a long rectal muscular cuff left for anocolic anastomosis might increase the incidence of postoperative enterocolitis and constipation. This study presents a modified transanal Soave pull-through procedure (MTSPP) which includes an oblique mucosectomy and an oblique anastomosis with a short split muscular cuff.

METHODSA review of two groups of HD patients was made: 112 underwent conventional transanal Soave procedure from 1999 to 2001 (group 1) and 140 underwent modified transanal Soave procedure from 2002 to 2004 (group 2). A comparison was made between the two groups on operative data and postoperative complications. The data included: age at the operation, operating time, blood loss, time to feeds and hospital stay, occurrence of postoperative enterocolitis or constipation, need for anal dilatation, postoperative bowel function and perianal skin problems.

RESULTSThere was no significant difference between two groups with respect to age, gender, length of colon resected, operating time, blood loss and hospital stay. However occurrence of postoperative enterocolitis, constipation, anastomotic stricture and time needed for anal dilatation were evidently less in group 2 (MTSPP). The mean operating time in group 1 was (106 +/- 39) minutes with a range of 60 to 170 minutes; in group 2 was (101 +/- 36) minutes with a range of 66 to 190 minutes. The average length of the bowel resected in group 1 was (24 +/- 7) cm, range 15 to 58 cm; in group 2 was (26 +/- 8) cm, range 15 to 70 cm. Two patients, one in each group, required laparoscopic assistance because of long aganglionic colon. Another patient in group 2 required laparotomy because of total colonic aganglionosis. Postoperative complications in group 1 included: temporary perianal excoriation in 34 patients (26 were < 3 months of age), enterocolitis in 21, anastomotic stricture in 11, recurrent constipation in 12, cuff abscess in 1, anastomosis leak in 1, soiling in 3 and rectal prolapse in 1. In group 2 post operative complications included: transient perianal excoriation in 37 patients (30 were < 3 months of age), enterocolitis in 13, anastomotic stricture in 5, recurrent constipation in 6, anastomotic leak in 1, adhesive bowel obstruction in 1 and soiling in 4. Complete bowel continence was found in 97 children (86.6%) in group 1 and in 129 children (92.1%) in group 2 at one year followup after operation.

CONCLUSIONSModified transanal Soave pull-through procedure for HD with oblique mucosectomy and anastomosis and a short split muscular cuff is a safe and feasible operation with low incidence of postoperative complication. It is an encouraging improvement of the conventional transanal Soave pull-through procedure. MTSPP is a preferable choice in the surgery of HD.

OBJECTIVETo investigate the association of the 4G/5G polymorphism located in the promoter region of plasminogen activator inhibitor-1(PAI-1) gene with prognosis of coronary artery disease (CAD) in Chinese Hans.

METHODSOne hundred and fifty five patients with CAD and 190 unrelated healthy control individuals were included in the study. The 4G/5G polymorphism was detected by polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP) analysis. A follow-up survey of major adverse cardiovascular event (MACE) and analysis of the relationship between the severity of coronary vessels and PAI-1 gene polymorphism were carried out.

RESULTS(1) The frequency of 4G/4G genotype of PAI-1 gene was higher in CAD patients than in controls (58/155, 37.42% vs 52/190, 27.37%, P< 0.01). (2) The frequency of 4G/4G genotype of PAI-1 in patients with MACE was higher than that in patients without MACE (40/81, 49.38% vs 18/74, 23.42%; P< 0.01). (3) The frequency of 4G/4G genotype in patients with multivessel disease was higher than that in patients with single-vessel disease (30/47, 44.77% vs 9/37, 24.32%; P< 0.05).

CONCLUSIONThe 4G/5G polymorphism located in the promoter region of PAI-1 gene was associated with prognosis of CAD patients, and may be regarded as a biomarker of the severity of the involved vessels.

Serum pharmacochemistry of traditional Chinese medicine (TCM) is designed to screen the efficacy material base of TCMs from the constituents absorbed into the blood after oral administration. The theory and method is in accordance with the effect characteristics of TCMs, and reflects the interaction between the body and the drugs, has become an effective pathway for researching the efficacy material base of TCMs which has been recognized and used widely. In the paper, the previous research contents and methods of the serum pharmacochemistry of TCM were reviewed, and on the basis of the further validity of the special administration form of the TCM formula and the corresponding property to TCM syndrome, the new strategy of serum pharmacochemistry of TCM integrating the metabonomics technologies was put forward. According to the strategy, we take the biological characters of TCM syndrome as a research starting point, taking TCM formula as object, using the metabolic biomarkers of syndromes or disease to evaluate the therapeutic effect of formula and screen the compounds of TCMs in serum which are highly correlated with the metabolic biomarkers through the correlation analysis, and by further biological validation to finally confirm the efficacy material basis of TCMs. Integrating with the systems biology technologies, the theory and method of serum pharmacochemistry of TCM will further develop, and open a new chapter in the interpretation of the theory of TCM.
