In the process of acid hydrolysis of medical absorbent cotton, we have discovered that some of the domestic manufactured medical absorbent cotton is mixed with wasted non-cotton chemical fiber. If the cotton is used in medical treatments, the chemical fiber will cause irritation, allergy and inflammation, so it's very harmful. But the non-cotton fiber content is not stipulated in the standard of YY0330-2002, and no testing method for it is available. In this paper we discuss the existent quality problems, the control and the test method for non-cotton chemical fiber in medical absorbent cotton.

Objective To investigate the clinic characters and diagnosis of superficial siderosis in the central nervous system (SSCN).Methods One patient was systematically studied by the authors. Results SSCN was a rare entity,resulting in the deposition of ferric pigments and ions on the surface of the central nervous system.The clinical features included progressive sensorineural hearing loss,cerebellar ataxia and pyramidal sign,widespread hypointensity band at surfaces of the cerebral or cerebellar hemispheres,the brain stem and the spinal cord on Gradient Echo T_2~*-weighted images (GRE-T_2~* WI) of MR,elevation of the levels of ferritin in the cerebrospinal fluid.Conclusions This disease can be identified at early stage with history and physical examination.GRE-T_2~* WI and some related cerebrospinal fluid tests will contribute to diagnosis.

Objective To investigate the apoptosis of T lymphocytes,the expression of Bcl-2, Fas on the peripheral blood T lymphocytes in end stage renal disease patients;and to explore the characteristics of Th1 /Th2 profile and the influence of dialysis membranes with different permeability on the apoptosis of T lymphocytes of maintenance hemodialysis patients.Methods The study included 10 non-dialyszed (ND)patients,45 maintenance hemodialysis patients with cellulose acetate (CA) membranes(13),low-flux polusulfone(PS-LF) membranes(16),high-flux polusulfone (PS-HF) membranes (16) and 8 healthy volunteers (C).The apoptosis of T lymphocytes,expression of Bcl-2,Fas on peripheral blood T lymphocytes cultured with phytohemagglutinin (PHA) stimulation for 24 hours were measured by flow cytometry and immunohistochemical.ELISA was performed for detecting the levels of IFN-?and IL-4 in culture supematants.Results In ESRD patients,the apoptosis of T lymphocytes was greater than that of group C.Group CA was greater than group PS-HF and group PS-LF (P＜0.05).The expression of Bcl-2 on T lymphocytes in ESRD patients was lower than that of group C (P＜0.05).There was negative correlation between the T lymphocytes apoptosis and Bcl-2. The expression of Fas on T lymphocytes in ESRD patients was greater than that of group C (P＜0.05), and it was positive correlated with T lymphocytes apoptosis.The level of IFN-?of ESRD patients was decreased significantly compared with that in group C (P＜0.05),and there was negative correlation between T lymphocytes apoptosis and IFN-?.IL-4 was increased in ESRD patients (P＜0.05) and it was positive correlated with T lymphocytes apoptosis.Conclusions The accelerated apoptosis of T lymphocytes in ESRD patients may be related to the expression of Bcl-2 and Fas of T lymphocytes.ESRD patients show a suppressed secretion of IFN-?and an increased secretion of IL-4. T lymphocytes apoptosis of maintenance hemodialysis patients is influenced not only by the biocompatibility but also by the permeability of the dialysis membrane.

OBJECTIVETo explore the method of rapid detection of skin fungi and the significance of conventional diagnosis liquor worker tinea corporis and tinea cruris using arbitrarily primed polymerase chain reaction AP-PCR.

METHODSAmong liquor workers who were 50 tinea corporis patients, 58 tinea cruris patients and 50 health persons, we amplified the DNAs of the dermatophytes were amplified using AP-PCR and random primers OPD18 5'-GAGAGCCAAC-3' and OPAA11 5'-ACCCGACCTG-3', at the same time, the dermatophytes with microscope were detected and cultured.

RESULTSAP-PCR analysis detected fungal DNA in 45 patients(90.00%) among 50 liquor worker patients with tinea corporis, 31 patients(62.00%) had the positive results of microscope detection, and 41 patients(82.00%) had the positive results of standard culture. Among these workers who suffered from tinea corporis, T.rubrum, T.mentagrophyte, M. canis and E.floccosum were detected by AP-PCR. T.rubrum, T.mentagrophyte and M.canis were detected by standard culture. AP-PCR analysis detected fungal DNA in 53 patients(91.38%) among 58 liquor worker patients with tinea cruris, 37 patients(63.79%) had the positive results of microscope detection, and 48(82.76%) had the positive results of standard culture. Among the 58 workers who had tinea cruris, T.rubrum, E.floccosum and T.mentagrophyte were detected by AP-PCR and standard culture. Among 50 health persons, AP-PCR analysis detected fungal DNA in 3 persons(6.00%). The detection result with AP-PCR indicated that the kinds of fungi were T.rubrum and T.mentagrophyte. No one health person had the positive result in detection of fungi using microscope detection. Only one(2.00%) health person was detected to be infected by fungus with cultural way. The kind of fungus was T.rubrum.

CONCLUSIONAP-PCR is a rapid, sensitive and specific detection method for occupational dermatophyte patients. It can be used to detect and diagnose professional dermatophytosis.

There is controversy regarding the roles of Ureaplasma urealyticum (U. urealyticum) colonization in the development of bronchopulmonary dysplasia (BPD). This study explored the association between U. urealyticum and bronchopulmonary dysplasia at 36 weeks post-menstrual age (BPD36). Studies published before December 31, 2013 were searched from Medline, Embase, Ovid, Web of Science, and Cochrane databases, with the terms "Ureaplasma urealyticum", "chronic lung disease", or "BPD36" used, and English language as a limit. The association between U. urealyticum colonization and BPD36 was analyzed with RevMan 4.2.10 software, using the odds ratio (OR) and relative risk (RR) for dichotomous variables. Out of the enrolled 81 studies, 11 investigated the BPD36 in total 1193 infants. Pooled studies showed no association between U. urealyticum colonization and subsequent development of BPD36, with the OR and RR being 1.03 (95% CI=0.78-1.37; P=0.84) and 1.01 (95% CI= 0.88-1.16, P=0.84), respectively. These findings indicated no association between U. urealyticum colonization and the development of BPD36.

OBJECTIVETo study the chemical constituents in hairy roots of Cassia obtusifolia.

METHODThe hairy roots of C. obtusifolia were induced with Agrobacterium rhizogenes LBA9402 from cotyledons and cultured in MSO liquid medium. The compounds were isolated by silica gel, polyamide and Sephadex LH-20 column chromatography, and the structures were elucidated by employing chemical and spectral methods

OBJECTIVETo study clinical effects of one-hole microplate internal fixation for the treatment of collateral ligament injuries of the metacarpophalangeal joint of the thumb combined with fracture.

METHODSTwenty-two patients (16 males, 6 females) with collateral ligament injuries of the metacarpophalangeal joint of the thumb combined fracture were treated with one-hole microplate internal fixation. The age of the patients ranged from 18 to 53 years old with a mean age of 28.5 years old. The duration from injury to surgery ranged from 2 hours to 2 months, and the mean time was 6 days. All the patients had collateral ligament injuries combined with fracture of the metacarpophalangeal joint of the thumb. Thirteen patients had injuries in the right hand and 9 patients had injuries in the left hand. There were 18 cases of closed wound and 4 cases of open wound. Eighteen patients had fresh injuries (< 2 weeks) and 4 had old injuries (> 2 weeks). Sixteen patients had injuries in the ulnar collateral ligament of the thumb combined with fracture, 6 patients had radial collateral ligament injuries of the thumb combined with fracture, 4 cases of which were complicated with injuries of abductor pollicis brevis and the end of the flexor pollicis brevis tender. The size of the avulsed fragment was about 3.0 mm x 4.0 mm to 6.0 mm x 7.0 mm.

RESULTSThe incisions of 22 patients healed by first intention. The follow-up periods ranged from 6 months to 5 years old,with an average of 2.5 years old. The thumb function was evaluated by Saetta and other evaluation criteria, and 20 patients got an excellent result and 2 good.

CONCLUSIONThe application of one-hole microplate internal fixation in treating collateral ligament injuries with fracture of the metacarpophalangeal joint of the thumb is an effective method.

BACKGROUNDDNA analysis has shown a lack of significant compatibility between couples affected by unexplained recurrent spontaneous abortion (URSA) compared with normal fertile couples, [8] although one study that made use of a PCR-sequence-specific oligonucleotide (SSO) method did observe evidence of significant compatibility in the HLA-DQA1 and DQB1 alleles between patients and aborted fetuses. [9] This study was designed to investigate whether URSA were associated with particular DQ alleles or promoter alleles.

METHODSThirty-two patients with URSA and 54 women who had had at least one successful pregnancy were included in this study. HLA-DQ genotyping was performed by the polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP) method. The HLA-DQB1 promoter was detected by the SSO and sequence-specific primer (SSP) methods. The DQA1, DQB1, and DQB1 promoter (QBP) gene frequencies in the patients were compared with the gene frequencies in normal controls. The data were analyzed statistically with the chi(2) and Fisher's exact tests.

RESULTSThe results showed that the frequency of DQB1 * 0604/0605 was significantly higher and the frequency of DQB1 * 0501/0502 was significantly lower in the patient group as compared with the normal controls. In addition, the frequencies of the DQA1 * 01-DQB1 * 0604/0605 and QBP6.2-DQB1 * 0604/0605 haplotypes were overrepresented in the patients relative to the controls. Our results did not show any differences between URSA patients and the controls with regard to DQA1 and QBP allele frequencies.

CONCLUSIONSOur data suggest that URSA is associated with the HLA-DQB1 coding region, and is not associated with its upstream regulatory region. The DQB1 * 0604/0605, DQA1 * 01-DQB1 * 0604/0605, and QBP6.2-DQB1 * 0604/0605 haplotypes may confer susceptibility to URSA, while the DQB1 * 0501/0502 allele may protect women from URSA.

BACKGROUNDIt is a surgical dilemma when patients present with both severe heart disease and neoplasms. The best surgical treatment remains controversial. This study aimed to analyze the early and long-term results of simultaneous surgical treatment of severe heart disease and neoplasms.

METHODSWe reviewed the clinical records of 15 patients who underwent simultaneous neoplastic resection and cardiac surgery between September 2006 and January 2011. There were 5 male and 10 female patients. The mean age was (59.2 ± 12.5) years and the mean left ventricular ejection fraction was (57.4 ± 11.0)%. All patients were followed up completely for a period of 12 to 51 months (mean, (33.1 ± 11.2) months).

RESULTSFifteen patients underwent simultaneous cardiac surgery and neoplastic resection. Cardiac procedures consisted of off pump coronary artery bypass grafting (n = 7), aortic valve replacement (n = 3), mitral valve replacement (n = 3), mitral valve replacement with coronary artery bypass grafting (n = 1) and left atrial myxoma resection (n = 1). Neoplastic resection consisted of lung cancer resection (n = 5), colonic cancer resection (n = 3), gallbladder resection (n = 1), colonic cancer resection with gallbladder resection (n = 1), hysterectomy (n = 2), hysterectomy with bilateral salpingo-oophorectomy (n = 2) and left ovariectomy (n = 1). Pathological examination confirmed malignant disease in 10 patients and benign disease in 5 patients. There were no perioperative myocardial infarctions, stroke, pericardial tamponade, renal failure or hospital deaths. The most frequent complications were atrial fibrillation (33.3%), pneumonia (26.7%), low cardiac output syndrome (6.7%) and delayed healing of surgical wounds (6.7%). There was 1 late death 42 months after surgery for recurrent malignant disease. At 1 and 3 years, survival rates were 100% (Kaplan-Meier method).

CONCLUSIONSSimultaneous cardiac surgery and neoplastic resection was not associated with increased early or late morbidity or mortality. Cardiopulmonary bypass does not appear to adversely affect survival in patients with malignant disease. The long-term survival was determined by tumor stage.
