OBJECTIVETo construct tissue-engineered neural complex in vitro and study its effect in repairing acutely injured spinal cord in adult rats.

METHODSNeural stem cells were harvested from the spinal cord of embryo rats and propagated in vitro. Then the neural stem cells were seeded into polyglycolic acid scaffolds and co-cultured with extract of embryonic spinal cord in vitro. Immunofluorescence histochemistry and scanning electron microscope were used to observe the microstructure of this complex. Animal model of spine semi-transection was made and tissue-engineered neural complex was implanted by surgical intervention. Six weeks after transplantation, functional evaluation and histochemistry were applied to evaluate the functional recovery and anatomic reconstruction.

RESULTSThe tissue-engineered neural complex had a distinct structure, which contained neonatal neurons, oligodendrocytes and astrocytes. After tissue-engineered neural complex was implanted into the injured spinal cord, the cell components such as neurons, astrocytes and oligodendrocytes, could survive and keep on developing. The adult rats suffering from spinal cord injury got an obvious neurological recovery in motor skills.

CONCLUSIONSThe tissue-engineered neural complex appears to have therapeutic effects on the functional recovery and anatomic reconstruction of the adult rats with spinal cord injury.

OBJECTIVETo investigate the effect of allogeneic leukocyte immunization combined with in vitro fertilization-embryo transfer (IVF-ET) for treatment of infertility induced by habitual abortion.

METHODSAllogeneic leukocyte immunization was performed in 9 patients with infertility induced by habitual abortion, with another 9 patients undergoing IVF-ET without habitual abortion as the control group. All the patients were treated with long GnRH-a protocols. The infertility patients with recurrent spontaneous abortion history were immunized with lymphocytes from the husband for before IVF-ET and after clinical pregnancy.

RESULTSThe fertilization rates of the immunotherapy group and control group were 81.3% and 82.2%, respectively, showing no significant difference (P>0.05). Five patients in each group had clinical pregnancy, and a twin pregnancy occurred in the control group. The embryo implantation rates were also comparable between the two groups (22.7% vs 28.6%, P>0.05). All the fetuses resulted from IVF-ET developed normally and were healthily delivered.

CONCLUSIONAllogeneic leukocyte immunotherapy along with IVF-ET is effective for treatment of infertility resulting from recurrent spontaneous abortion.

OBJECTIVETo study the clinical and epidemiologic characteristics and the serum types of enterovirus of hand, foot and mouth disease (HFMD) in children.

METHODSThe RT-nPCR method was established with universal primers within 5' untranslated region of enterovirus and VP1 region of Coxsackievirus A16 (CAV16) and enterovirus 71 (EV 71). Enteroviruses were detected with RT-nPCR in 237 children with HFMD. Clinical and epidemiologic characteristics and serum types of enterovirus of the patients with HFMD were studied.

RESULTSThe patients'age ranged from 7 months to 11 years (mean 4.2 +/- 0.5 years). The majority (94.5%) were less than 6 years old. HFMD was mostly seen in spring and winter (67.9%). Oral mucosal pox or ulcer as well as hand and foot rashes were observed in all 237 patients. Fever occurred in 141 patients (59.5%). Of the 237 patients, 133 (56.1%) were RT-nPCR positive. Of the 133 cases, 38 were positive for EV71, 64 were positive for CAV16, and 31 were negative for both EV71 and CAV16. The patients infected by different types of enteroviruses had similar clinical characteristics. Gene colon and sequence analysis for 12 strains of enteroviruses PCR positive products presented as EV71 (n=5), CAV16 (n=5), ECHO13 (n=1), and CAV5 (n=1).

CONCLUSIONSHFMD tends to occur in younger children less than 6 years old. The majority are affected in spring and winter. EV71 and CAV16 are common pathogens of HFMD. There is no relationship between clinical characteristics and serum types of enteroviruses in HFMD patients.

OBJECTIVETo evaluate the efficacy and safety of 0.9-ms 1064-nm Nd:YAG laser alone or combined with itraconazole for treatment of toenail onychomycosis.

METHODSA total of 37 patients with onychomycosis (178 toenails) were randomly assigned to groups A and B, and each group was further divided into different subgroups according to the Scoring Clinical Index of Onychomycosis (SCIO) and Onychomycosis Severity Index (OSI) scoring. All the patients were treated with 0.9-ms Nd:YAG laser once a week for 8 times. The patients in group A were treated with laser alone, and those in group B were treated with laser combined with itraconazole. The clinical effect, clinical scores, appearance of the toenails and adverse reactions in the two groups were analyzed, and the patients' satisfaction rate was also investigated.

RESULTSAt the 12th months of follow-up, the clinical response rate and mycological cure rate in group A were 31.33% and 30.00%, respectively, similar to the rates in group B (35.79% and 41.18%, respectively) (P>0.05). After the treatments, the SCIO and OSI scores showed no significant changes in group A (P>0.05) but both increased significantly in group B (P<0.05). The response rates did not differ significantly among the subgroups with SCIO<12 or with OSI<16 (P>0.05), but showed significant differences among the subgroups with SCIO≥12 or with OSI≥16 (P<0.05). Of the total of 178 toenails, 33.71%, 74.72% and 70.79% toenails showed improvements in terms of clear nail growth, shape and color, respectively. The overall patients' satisfaction rate was 62.16%, and no adverse reactions related with the therapy were recorded in these patients.

CONCLUSIONFor treatment of toenail onychomycosis, 0.9-ms 1064-nm Nd:YAG laser can effectively improve the aesthetic appearance of the toenails, and a combined treatment with Nd:YAG laser and itraconazole can be better option in severe cases of onychomycosis.

OBJECTIVETo evaluate the efficacy and safety of long pulse 1064 nm Nd:YAG laser therapy in the treatment of onychomycosis of the toenails.

METHODSA total of 104 patients with onychomycosis (461 toenails) were divided by age into ≥60 years group and <60 years group, and each group was further divided into subgroups according to Scoring Clinical Index of Onychomycosis (SCIO) scoring and the location of the compromised toenails. All the toenails were treated with 10 to12 sessions of long pulse 1064 nm Nd:YAG laser therapy at the interval of 1 week. All the patients were followed up for 48 weeks after the initial treatment to assess the clinical efficacy and adverse reactions.

RESULTSThe overall clinical response rate in these patients was 72.5% by the end of the 48-week follow-up. In patients aged <60 years, the clinical response rate and mycological cure rate were significantly higher than the rates in patients aged ≥60 years (P<0.05). No significant differences were observed in the response rates between different SCIO subgroups (P>0.05); the 2nd to 4th toenails showed better outcomes after the therapy than the 1st and 5th toenails (P<0.05). No adverse reactions related with the therapy were recorded in these patients.

CONCLUSIONLong pulse 1064 nm Nd:YAG laser is an effective and safe approach for treatment of onychomycosis of the toenails.

OBJECTIVEScrub typhus is an infectious disease due to Orientia tsutsugamushi transmitted by infected chigger mites. Scrub typhus has long been recognized to occur in southern areas of China, but has recently been increasingly often reported from the north since the first case was reported in Mengyin County, Shandong Province in 1986. The key objectives of the present study were to investigate the clinical manifestations and epidemic factors of scrub typhus in children from the northern new natural foci.

METHODSThe case records of 56 children with scrub typhus who were admitted to the 5 hospitals of Fei County from September 1993 to January 2004 were reviewed. Orientia tsutsugamushi (Ot) was isolated from the cases. Based on ecological observations on the composition, seasonal fluctuation of animal hosts and chigger mites, Ot was isolated from rodents and chiggers. IgG antibodies to Ot was detected by IFA. Genotypes of the Ot isolates were also identified by nested PCR.

RESULTSAmong 56 children scrub typhus cases, 46 were male, 10 were female; 96% exhibited typical eschars or ulcers, 100% cases had high fever, skin rashes were observed in 55 cases (98%), and regional lymphadenopathy occurred in 48 cases (86%). All cases came from countryside, and all had histories of exposure to the crop field. fifty-one serum samples of suspected patients with scrub typhus were collected, 48 were positive for antibodies to Ot. The serotypes were Gilliam types. The cases only appeared in September to December with the peak at mid and late October. Leptotrombidium (L.) scutellare was the most important vector causing scrub typhus in the foci. Apodemus (A.) agrarius was the main host animals of Ot in the crop field. Totally 26 strains were isolated from patients, rodents, and chigger mites. The serotypes of 24 out of the 26 isolates were Gilliam types, while the genotypes of these isolates were Kawasaki types. The serotypes of the other 2 isolates were identical and both were Karp types.

CONCLUSIONChildren scrub typhus patients were frequently seen in the new natural foci of Shandong province. Exposure history, typical eschars or ulcers, and presence of IgG antibody were the important indexes to diagnose the disease.
