Objective To explore the composition and distribution law of TCM syndromes in gastric cancer. Methods Based on the multicenter and large-sample clinical epidemiological investigation, the four methods of diagnosis of and clinical materials of 767 cases of gastric cancer were collected, and the database of TCM syndromes in gastric cancer was establish. Factor analysis and clustering analysis were used to explore composition and distribution law of TCM syndromes in gastric cancer. Results Gastric cancer symptoms mainly included fatigue, weight loss, dizziness and other non-specific systemic manifestation, and epigastria discomfort, belching, fullness or eating just a little swelling, pain, acid regurgitation, loss of appetite and other local manifestations. At the same time, the red tongue, moss greasy, pulse fine or string and other traditional Chinese medicine signs were also included. Eliminating 92 cases with too little symptoms, 675 cases were under multivariate analyzed. 25 syndrome variables were selected after initial factor analysis, again through factor analysis 10 factors with eigenvalues more than 1.0 were obtained and the cumulative contribution rate was 60.5%. Through further K-means clustering analysis on 10 common factor integrals, it was found that when all the cases were clustered into 7 classes consistent with clinical practice most. The numbers of patients with the 1-7 type were 165, 82, 90, 79, 88, 95 and 76, respectively. Analysis on the main factors in the combination of professional knowledge, the 7 types were named as the syndrome of spleen and stomach qi stagnation (24.44%), the syndrome of qi and blood deficiency (12.15%), the syndrome of spleen deficiency (13.33%), the syndrome of blood stasis (11.70%), the syndrome of phlegm dampness (13.04%), the syndrome of deficiency cold of spleen and stomach (14.07%), the syndrome of incoordination between liver/gallbladder and stomach (11.41%) respectively. Conclusion The results of multivariate analysis suggests that the location of gastric cancer is in the stomach, and closely related to spleen, liver and gallbladder. The general pathogenesis is asthenia in origin and asthenia in superficiality. The deficiency lies in qi, blood and yang qi, while asthenia superficiality owes to stagnation of qi, phlegm and blood stasis.

OBJECTIVETo evaluate the brain pathological changes following exdogenous neural stem cells (NSCs) intraventricular transplantation in neonatal rats with periventricular leukomalacia (PVL), and to explore the feasibility of NSCs transplantation for the treatment of PVL in premature infants.

METHODSNSCs were prepared from E14 embryonic rat brain. Two-day-old neonatal rats were randomly divided into six groups: PVL, PVL+culture medium, PVL+NSCs, sham operation, sham operation+culture medium, and sham operation+NSCs (18-21 rats each group). Intraventricular transplantation of exdogenous NSCs was performed 72 hrs after PVL induction or sham operation. The cerebral pathological evaluation was undertaken by light microscopy 7, 14 and 21 days after transplantation.

RESULTSThe pathological changes in the cerebral white matter were gradually improved with the prolonged time after transplantation. After 21 days of transplantation, 50% of the cerebral white matter showed mild pathological changes and 50% of that showed severe pathological changes, with neuronal pathological scores of 1.28+/-0.86, in the untreated PVL group. In the PVL+NSCs group, 30% of normal white matter, 40% of mild and 30% of severe pathological changes in the white matter were observed, with neuronal pathological scores of 0.32+/-0.16, 21 days after transplantation. There were very significant differences in both of pathological changes in the cerebral white matter and neuronal pathological scores between the PVL and PVL+NSCs groups (x2=10.7, P<0.01; F=29.664, P<0.01).

CONCLUSIONSIntraventricular transplantation of exdogenous NSCs can apparently improve cerebral white matter damage. It is suggested that intraventricular transplantation of NSCs is of a great potential feasibility for the treatment of PVL in premature infants.

OBJECTIVETo summarize and analyze the diagnosis and arthroscopic treatment of osteochondral lesion of talus (OLT).

METHODSFrom 2000 to 2005 the data of 34 patients of OLT of the talus were retrospectively studied, including the symptom, physical examination, image, arthroscopic treatment All patients took X-ray and MRI examination before the arthroscopic surgery. Arthroscopic debridement was performed for all patients, in addition to drilling in 5 cases, and microfracture in 18 cases. Before operation, ankle-hindfoot score of American Orthopaedic Foot and Ankle Society (AOFAS) was 71 +/- 8, and the score of pain (visual analogue scale, VAS) was 7.5 +/- 1.3.

RESULTSWeight-bearing pain of the ankle joint aggravated after exercise was the predominant complaint of OLT. X-ray examination was negative in 13 cases, and all lesions were detected by MRI, which was significantly better than X-ray (chi2 = 16.07, P < 0. 001). Thirty-one patients were followed up for an average of 28 months. The average post-operative AOFAS was 91 +/- 9 (t = 9.147, P < 0.001); And VAS was 2.4 +/- 2. 3, which was significantly lower than that in pre-operation (t = 10.853, P < 0.001). Of the 31 patients, 27 (87.1%) had good or excellent results.

CONCLUSIONSMRI could improve the accuracy of diagnosis. The results of arthroscopic treatment for OLT are satisfactory.

OBJECTIVETo establish a reliable neonatal rat model of periventricular leukomalacia (PVL) which is expected to be similar to PVL of human preterm infants pathologically, and to explore the concomitant eye lesions in the PVL model.

METHODSTwo-old-day neonatal rats were randomly divided into a PVL group and a sham-operated group (n=19 each). The PVL model was established by the ligation of bilateral common carotid arteries, followed by a 30-min exposure to 8% oxygen. The cerebral infarction area was assessed with TTC staining 1 day after operation. Cerebral pathology was examined under a light micsrocope 2 and 21 days after operation. The examinations of eyes under a slip lamp and the pathology of eyeballs under a light microscope were performed 21 days after operation.

RESULTSThe TTC staining cerebral slices showed there were extensive white areas of infarction in the brain of the PVL group, with an infarction area of 53.45 +/- 33.90 mm3 and a percentage of infarction of (24.98 +/- 15.44)% . Significant cystic necrosis and apoptosis around the periventricular and subcortical white matter and mild damage in cortical neurons were observed in the PVL group 2 days after operation. The more obvious cystic necrosis around the periventricular area was found in the PVL group 21 days after operation. There were no pathological changes in the brain of the sham-operated group. All of rats in the PVL group had bilateral cataracts, however, no pathological changes were observed in their postbulbar tissues. The sham-operated group did not show eye abnormal.

CONCLUSIONSThe PVL animal model that was similar to PVL of human preterm infants pathologically was successfully established by the ligation of bilateral common carotid arteries, followed by 30-min hypoxia exposure, with a positive effect and a good repeatability. Cataract can also be induced by the method.

OBJECTIVETo evaluate the diagnosis and management of adrenal myelolipoma.

METHODSThe clinical data of 26 cases were analyzed retrospectively and the selected articles were reviewed. There were no specific clinical symptom and endocrine abnormality, except increasing catecholamine in 2 cases. All cases but two were diagnosed by B-model ultrasound scanning (B-US), CT or magnetic resonance imaging (MRI).

RESULTSTwenty-six cases were surgically treated, the diameter of the tumor was 5 - 10 cm, simple tumor resection was performed in 16 cases, and complete adrenal resection was performed in 10 cases. All the operated cases were proved by pathologists. The duration of follow-up was from 6 - 28 months after surgery. No recurrence was observed.

CONCLUSIONSThe diagnosis of adrenal myelolipoma could be established based on B-US, CT or MRI. The tumors whose diameter is larger than 5 cm in size should be removed.

BACKGROUNDCompared with traditional arthrotomy procedures, arthroscopic treatment for osteochondral lesions of the talus has some advantages. However, there has been considerable debate about the outcome predictors for this surgical technique. This study aimed to investigate the outcomes of arthroscopic treatment for osteochondral lesions of the talus, and analyze its outcome predictors.

METHODSClinical data of 48 patients with osteochondral lesions of the talus who underwent ankle arthroscopy were studied. Arthroscopic debridement was performed on all patients, and microfracture was also performed in 36 cases. Scores on a subjective satisfaction questionnaire, visual analog scale (VAS) for pain, and the American Orthopedic Foot & Ankle Society (AOFAS) ankle and hindfoot scores were obtained before and after surgery.

RESULTSFive patients lost to follow up. The other forty-three patients, 8 of whom were athletes, were followed up for an average of 23.9 months. The average AOFAS post-operative score was 90.16 +/- 9.96, compared with 70.81 +/- 6.96 before surgery (t = 9.353, P < 0.001). The VAS pain score after the operation (2.51 +/- 2.45) was significantly lower than that before the operation (6.95 +/- 1.40) (t = 8.647, P < 0.001). Of the 43 patients, 35 (81.4%) had good or excellent results. There was no significant difference in outcome between the medial and lateral groups (z = 0.205, P = 0.838), while a better outcome was found with lesions smaller than 10 mm than those with larger lesions (z = 2.199, P = 0.028). Age, sex, athletic profession and location of the lesion did not significantly correlate with outcomes.

CONCLUSIONSArthroscopic treatment is effective and safe for osteochondral lesions of the talus. A strong correlation was found between the size of the lesion and successful outcome.

We conducted a prospective study of erectile dysfunction (ED) after urethral reconstructive surgery, using the 5-item International Index of Erectile Function (IIEF-5), the Sexual Life Quality Questionnaire (SLQQ) and the Quality of Life Questionnaire (QoLQ). Between January 2003 and July 2007, 125 male patients with urethral strictures underwent urethroplasty, and pre- and post-surgery erectile function was assessed using these three questionnaires. A formula to predict the probability of ED after urethroplasty was derived. At 3 months post-operatively, there was a significant decrease in IIEF-5 (16.57 +/- 7.98) and SLQQ scores (28.71 +/- 14.84) compared with pre-operative scores (P < 0.05). However, the IIEF-5 scores rebounded at 6 months post-operatively (17.22 +/- 8.41). Logistical regression analysis showed that the location of the urethral stricture, the recurrence of strictures and the choice of surgical technique were predictive of the post-operative occurrence of ED. This study identified the clinical risk factors for ED after urethroplasty. Posterior urethral stricture and end-to-end anastomosis were found to have a strong relationship with erectile function. The logistical model derived in this study may be applied to clinical decision algorithms for patients with urethral strictures.

BACKGROUNDUrethroplasty of complex urethral stricture is a difficult procedure, and there is no widely accepted standard approach described in the published literature. We evaluated the efficacy and safety of urethroplasty using lingual mucosa grafts (LMGs) for the repair of urethral strictures.

METHODSBetween August 2006 and April 2009, 92 cases of urethral strictures (length ranging from 2.5 cm to 18 cm, mean 6.5 cm) were treated using LMGs. Of the 92 patients, 38 with long-segment urethral strictures (9 - 18 cm) underwent dual LMG or LMG combined with foreskin flap or buccal mucosal graft urethroplasty.

RESULTSFollow-up was obtained for 3 - 33 months (mean 17.2 months) postoperatively. Complications occurred in 8 patients, including urinary fistulas in 4 patients; recurrent strictures developed in 4 patients at 3 - 4 months post-operatively. The remaining patients voided well postoperatively, with peak flows between 14.3 ml/s and 54.6 ml/s (mean 28.4 ml/s).

CONCLUSIONSThe tongue is an excellent source of graft material for the repair of anterior mucosal strictures. Dual LMG substitution urethroplasty can successfully treat longer, more complex urethral strictures.

OBJECTIVEWe reported here the clinical and genetic evaluations as well as mutational analysis of mitochondrial DNA(mtDNA) in a Chinese family with maternally transmitted non-syndromic hearing loss and investigated the influence of the mitochondrial tRNA(Asp) A7551G mutation to the phenotypic manifestation of the deafness.

METHODSOne Chinese Han pedigrees of maternally transmitted nonsyndromic hearing loss were collected. The proband and family members underwent clinical, genetic, and molecular evaluations, such as audiological examinations, mutational analysis of mitochondrial genome and mutational analysis of GJB2 gene.

RESULTSSix people of this pedigree suffered from hearing loss, including four matrilineal members, and others did not have significant clinical abnormalities. Sequence analysis of the complete mitochondrial genome in the proband showed that there were 28 mtDNA polymorphisms belonging to East -Asian haplogroup A4.In addition to the A7551G homogeneity mutation, there were no other functionally significant variants found in this family. The A7551G mutation located immediately at the three prime end to the anticodon, corresponding with the conventional position 37 of tRNA(Asp), and its' CI value was 100% compared with other 15 primate species. The A7551G mutation was absent in other Chinese controls. The mutations on GJB2 were detected by direct sequence analysis,GJB2 235delC and 299delAT which was associated with hearing loss were found in the genomic DNA of the proband and some matrilineal members. Clinical evaluation showed a variable phenotype of severity, age-at-onset and audiometric configuration of hearing loss in the matrilineal relatives in these families.

CONCLUSIONSThe A7551G mutation may modify the secondary structure of the tRNA, and affect the stabilization of tRNA(Asp), produce non-normal functional tRNA(Asp) ultimately. And it may cause the phenotypic manifestation of the deafness that associated with A7551G mutation. Therefore, the mitochondrial tRNA(Asp) A7551G mutation may be a new mitochondrial mutation for hearing loss.
