OBJECTIVETo explore the integrative medicinal therapy for non-gonococcal cervicitis (NGC) in order to elevate the therapeutic effect for patients treated in vain after long-term application of antibiotics.

METHODSFifty patients with NGC were treated with Qingyuan decoction combined with antibiotics, and other 46 patients were treated with antibiotics alone for control.

RESULTSThe cure rate and significant effective rate was 90.0% (45/50) and 65.2% (30/46) in the treated group and the control group, it was significantly different between the two groups (chi2 = 9.58, P < 0.01). The disappearance rate of symptom was 88.1% and 41.4% in the two group after treated for two weeks respectively, and it was also significantly different (chi2 = 12.42, P < 0.01).

CONCLUSIONSThe therapeutic effect of NGC treated by sensitive antibiotics combined with Qingyuan decoction is better than that treated with western medicine only.

OBJECTIVETo investigate the characteristics of 24-hr ambulatory electrocardiography (DCG) of children with myocarditis and to study the clinical value of DCG in the diagnosis of childhood myocarditis.

METHODS24-hr DCG findings, including abnormal DCG rate, and number, grade and distribution of ventricular premature beat (PVC), as well as heart rate variability, from 59 children with myocarditis were retrospectively reviewed and compared with those detected in 41 children without heart disease.

RESULTS86.4% of patients with myocarditis showed abnormal DCG, and compound arrhythmia was commonly seen, but only 46.3% showed abnormal DCG (P < 0.01) and single arrhythmia was predominant in the control group. The number and grade of PVC/24 hrs were not significantly different between the two groups. Compared with the control group, the average pattern PVC was predominant in the myocarditis group (84.6% vs 48.7%; P < 0.05). Monopeak pattern PVC was mostly seen (64.4%), followed by multiple-peak pattern (25.4%) and bi-peak pattern (8.4%) in the myocarditis group, which were significantly different from the control group: monopeak pattern 53.6%, bi-peak pattern 36.6% and multiple-peak pattern 7.3% (P < 0.01).

CONCLUSIONSThe 24-hr DCG characteristics of children with myocarditis are different from the normal controls, suggesting 24-hr DCG monitoring is useful to the diagnosis of childhood myocaditis.

OBJECTIVETo explore polarization of T lymphocyte and its relationship with apoptosis of marrow cells in patients with myelodysplastic syndromes (MDS).

METHODSMeasurements of Th1, Th2, Tc1, Tc2 subsets in bone marrows from 34 patients with MDS and 13 normal controls were performed by flow cytometry. INF-gamma and TNF-alpha in marrow serum were determined by ELISA (Enzyme-linked immunosorbent assay). Apoptosis index of marrow cells was detected by TUNEL (TdT-mediated dUTP nick end labeling). Correlations between Th1, Th2, Tc1, Tc2 subsets and INF-gamma, TNF-alpha levels as well as apoptosis index were analyzed, and relationship between TNF-alpha, INF-gamma levels and apoptosis index was also investigated.

RESULTS(1) The percentage of Th1 cells [(10.1 +/- 1.6)%], Tc1 cells [(24.0 +/- 3.6)%] and Tc1/Tc2 ratio (50.0 +/- 11.1) was significantly increased in patients with MDS than in normal controls [(4.0 +/- 0.5)%, (5.8 +/- 0.6)% and 13.4 +/- 2.7, respectively]. Levels of INF-gamma [(58.6 +/- 21.7) microg/L] and TNF-alpha [(15.7 +/- 3.8) microg/L] in marrow serum of MDS patients was markedly elevated compared to normal controls [0 and (0.3 +/- 0.2) microg/L, respectively]. An increased apoptosis index of nucleated cells was observed in MDS patients [(7.8 +/- 1.5)%] as compared to controls [(2.1 +/- 0.3)%, P < 0.05]. The Th1 cell percentage showed a positive correlation with the levels of INF-gamma and TNF-alpha (r = 0.38, P < 0.05 and r = 0.39, P < 0.05, respectively), and with apoptotic index of nucleated marrow cells in MDS patients (r = 0.33, P < 0.05). Furthermore, a positive correlation was observed between INF-gamma, TNF-alpha levels and apoptotic index of marrow cells (r = 0.74, P < 0.01 and r = 0.73, P < 0.01, respectively). (2) Th1, Tc1 cells and Tc1/Tc2 ratio in MDS-RCMD patients was markedly elevated (P < 0.01) but did not in RCMD-RS, RAEB-1 and RAEB-2 patients as compared to normal controls. (3) An elevation in the percentages of Th1, Tcl and Tc1/ Tc2 ratio was detected in patients with IPSS lower-risk but did not in higher-risk group as compared to controls. (4) Increased Th1 and Tc1 percentages and Th1/Th2 and Tc1/Tc2 ratios were observed in RCMD patients with normal karyotype, but did not in those with abnormal karyotype. Conclusions Th1/Th2 and Tc1/Tc2 in bone marrow of MDS patients were unbalanced, polarizing to type I reaction especially in patients with RCMD subtype, IPSS lower-risk and normal karyotype. The increased Th1 cells in bone marrow may account for the increased apoptosis of nucleated marrow cells in MDS, through proapoptotic cytokines such as INF-gamma and TNF-alpha.

OBJECTIVETo investigate the biological difference of clonal cells between myelodysplastic syndromes (MDS) and acute myeloid leukemia (AML).

METHODBone marrow (BM) clonal cells (which had cytogenetic markers detected by FISH assay) and blasts were quantitatively analysed in 51 MDS and 11 AML patients. The clonal cell percentage in orthochromatic normoblasts, granulocytes and megakaryocytes were assayed. The biological functions for phagocytosis and oxidation of MDS peripheral blood (PB) neutrophils were compared with that of normal controls.

RESULTSAlmost all MDS patients BM had a higher clonal cell percentage (mean 48.2%) than blasts percentage (mean 6.7%) (P < 0.01), but with the subtype of MDS advancing this percentage gap was closing up, and in 11 AML patients no such gap was observed. This gap in MDS patients with + 8 abnormality was smaller than in those with 5q -. In MDS BM, clonal cells were detected in segmented granulocytes (mean 45.9%), orthochromatic normoblasts (mean 46.0%) and mature megakaryocytes (mean 38.0%). In Addition, an approximate amount of clonal cells with the same karyotype abnormality in BM were detected in MDS PB (mean 37.3% in blood vs 48.6% in marrow). Functional analysis showed that the neutrophils in MDS PB could exert nearly normal physiological functions (P > 0.05), but those from AML could not as compared to healthy donors (P < 0.01).

CONCLUSIONThere is a significant difference in the biological features between MDS and AML clonal cells.

objective To analyze the characteristics of high download frequency paper of Chongqing Medical Journal. Methods The top 150 high download frequency papers published in Chongqing Medical Journal were collected from CNKI database to analyze the total download frequency, download frequency of single papers, citation frequency, single paper citation frequency, authorship, affiliations, funding, and published columns. Results For the 146 high download frequency papers, the download frequency averaged 2035 times with a citation frequency of 71 103 times, showing a low correlation between download frequency and citation frequency (r=0.250, P=0.250). In the high download frequency papers, the top 3 were published in columns of review (54.1%), original articles (21.9%), and hospital or health management (7.5%). The first authors came mainly from Chongqing Medical University and the affiliated hospitals and Third Military Medical University and its affiliated hospitals. Sixty-one papers(41.78%) had signature of our editors or reviewing experts, 31 (21.23%) had funding support. The average time length from publish to download was (6.35 ± 2.36) years (range 4-8 years). Conclusion There is a correlation between the download frequency and citation frequency among the high download frequency papers of Chongqing Medical Journal; the actual published small columns, but cited frequency is not high necessarily; local medical research resources are still the main source of publication quality manuscripts. The probability of paper with fund support is higher than paper without fund support.

Central nervous system lymphatic drainage system (CNSLDS) is composed of glymphatic system, perivascular lymphatic drainage pathways and meningeal lymphatic vessels. Based on new findings of structures and functions of CNSLDS, CNSLDS is one of the mechanisms for promoting the clearance of β-amyloid (Aβ). CNSLDS functions physiologically as a route of drainage for Aβ from glymphatic system or perivascular lymphatic drainage pathways to meningeal lymphatic vessels, and the meningeal lymphatic vessels helps Aβ drainage to the nearby lymph nodes. In this review, we summarize the key component elements (structure and function) in the clearance of Aβ during the CNS lymphatic drainage. Also, we highlight their potential roles in the pathogenesis of Alzheimer's disease and their clinical importance in diagnosis and treatment of neurologic diseases associated with Aβ, including Alzheimer's disease.

Cockayne syndrome is a rare autosomal recessive disease. This paper reports a case of Cockayne syndrome confirmed by gene analysis. The baby (male, 7 years old) was referred to Peking University Third Hospital with recurrent desquamation, pigmentation and growth and development failure for 6 years, and recurrent dental caries and tooth loss for 2 years. Physical examination showed very low body weight, body length and head circumference, yellow hair, a lot of fawn spots on the face, skin dry and less elastic, and subcutaneous lipopenia. He had an unusual appearance with sunken eyes, sharp nose, sharp mandible, big auricle and dental caries and tooth loss. Crura spasticity and ataxia with excessive tendon reflexion, and ankle movement limitation while bending back were observed. He had slured speech. The level of serum insulin like growth factor I was low, and the results of blood and urinary amino acid analysis suggested malnutrition. The results of blood growth hormone, thyroxin, parathyroxin, liver function, renal function, lipoprotein profile and blood glucose and electrolytes were all within normal limit. An electronic hearing examination showed moderate neural hearing loss. The sonogram of eyes revealed small eye axis and vitreous body opacity of right side. MRI of brain revealed bilateral calcification of basal ganglia and generalized cerebral and cerebellar atrophy, and brainstem and callus were also atrophic. Genetic analysis confirmed with CSA gene mutation. So the boy was definitely diagnosed with Cockayne syndrome. He was discharged because of no effective treatment.

OBJECTIVETo study the relationship between angiotensin converting enzyme (ACE) gene insertion/deletion (I/D) polymorphism and left ventricular mass (LVM) in newborns admitted to the neonatal intensive care unit (NICU).

METHODSSeventy-two newborns admitted to the NICU were enrolled. ACE genotypes were determined by genomic DNA which was isolated from heel-prick blood. Disease status of the newborns was evaluated by the Neonatal Critical Score (draft) on postnatal day 1. LVM and LVM index (LVMI) were evaluated by echocardiography on postnatal days 1-3.

RESULTSDD genotype was identified in 11 cases, ID genotype in 31 cases, and II genotype in 30 cases. There were no significant differences in clinical characteristics, critical score and body measurements in newborns with different genotypes. The DD genotype group showed significantly lower LVMI than the group with ID+II genotypes (29±4 g/m2 vs 35±8 g/m2; P<0.05).

CONCLUSIONSACE gene polymorphism is associated with the LVMI in newborns admitted to the NICU. The LVMI of DD genotype carriers is significantly lower than that of ID+II genotypes carriers, which suggests that D allele may be associated with the growth and development of left ventricular.
