The patient,a 11-year-old boy,presented with a 4-year history of erythema and vesicles on the face and arms as well as a 4-month history of tumor and ulcer on the extremities,accompanied by progressive fatigue and intermittent fever.The patient had a body temperature of 37.7℃.No lymph node involvement was observed.Cutaneous examination revealed minimally indurated pink-red patches on the face and nose and dusky red firm nodules and tumors of varying sizes on the extremities.The nodules ranged from 2.0 cm to 18 cm in diameter,some had necrosis and black crusts on the surface.Ulcers were observed in some of the larger nodules;many of the ulcers extended into the muscle layer.White purulent discharge was seen on the surface of many of the nodules.The lesions were sharply demarcated,firm,tender, and surrounded by small satelite nodules.Histologically,there were large quantities of irregularly shaped, middle-sized tumor cells with clear cytoplasm,large twisted nuclei and prominent chromatin,infiltrating from the epidermis to subcutaneous tissue.The tumor cells infiltrating the follicles and eccrine sweat glands were either distributed perivascularly in a nest shape,or dispersed.There were broken nuclei and reactive histio- cytic infiltration in the dermis and subcutaneous tissue.Immunohistologically,the tumor cells were positive for cytoplasmic CD3 around the nuclei,for CD56,CD45RO and T cell intracellular antigen-l,and partly for CD30,CD8 and Ki67.Epstein-Barr virus-encoded nuclear RNA was positive with in situ hybridization. TCR?-2 gene rearrangement was positive in these tumor cells.A diagnosis of hydroa vacciniforme-like primary cutaneous NK/T-cell lymphoma was made.Therefore,this is a case report of hydroa vaccini- forme-like primary cutaneous NK/T-cell lymphoma with primary involvement in the skin;the condition was slowly progressive over 51 months.

OBJECTIVETo study the effect of close needling in the treatment of calcifying tendonitis.

METHODSSeventeen patients with calcifying tendonitis who had received close needling treatment were followed-up for 9.3 months on average. An 18-gauge or 16-gauge needle was used during needling. X-ray examination was given 4, 6, 8 and every 4 weeks after needling. SST (simple shoulder test) questionnaire, ASES (American Shoulder & Elbow Surgeon) score, constant-Murley score and UCLA score were adopted for evaluation before and after treatment.

RESULTSCalcium deposition disappeared within 4 - 20 weeks mean 9.4 weeks in 15 of the 17 patients after needling for 1 - 3 times. Average ASES score before treatment was 47.7 (34 - 59), forward elevation was 90 degrees (70 degrees - 100 degrees ), external rotation was 15 degrees (0 degrees - 30 degrees ), and internal rotation was L3-4 (L1-buttock). Average constant-Murley score before treatment was 44.6 (34 - 54), UCLA score was 11.6 (8 - 15), and numbers of questions for "yes" in SST questionnaire was 3.4 (2 - 5). After needling the average ASES score was 87.1 (72 - 91), forward elevation was 143.5 degrees (120 degrees - 160 degrees ), external rotation was 40 degrees (30 degrees - 50 degrees ), internal rotation was T(8)-T(9), constant-Murley score was 87.8 (64 - 94), UCLA score was 29.5 (19 - 33), and numbers of questions for "yes" in SST questionnaire was 9.1 (6 - 12). Significant difference was found between before and after needling (ASES: P < 0.01, forward elevation, external rotation and internal rotation: P < 0.01, constant-Murley: P < 0.01, UCLA: P < 0.01, SST: P < 0.01).

CONCLUSIONSClose needling is an effective method for the treatment of calcifying tendonitis. Symptoms and disability are greatly relieved non-surgically in most of patients. Care should be taken in differential diagnosis of degenerative calcification in chronic rotator cuff disease.

OBJECTIVEThe indication, surgical techniques and results had been discussed through clinical analysis of percutaneous pinning for the treatment of proximal humerus fractures.

METHODSForty-nine patients with 49 shoulders treated with percutaneous pinning had been reviewed with a mean follow-up period of 16.9 months. All were acute fractures, with a mean age of 40.4 years. There were 39 2-part surgical neck fractures, 6 impacted 2-part greater tuberosity fractures and 4 valgus-impaction 4-part fractures. SST (Simple Shoulder Test) questionnaire, ASES (American Shoulder & Elbow Surgeon) score, Constant-Murley score and UCLA score had been adopted for final evaluation at the latest follow-up.

RESULTSThe mean ASES score was 91.4, the mean VAS score was 1.7, the mean forward flexion was 146.7 degrees, external rotation 39.6 degrees, internal rotation at T(8)-T(9) level; the mean Constant-Murley score was 88.2; the mean UCLA score was 31.2; the mean number of questions for "yes" in SST questionnaire was 10.1. All fractures healed with a mean period of 8.8 weeks. No patient had been found for any evidence of humeral head necrosis at the latest follow-up The total satisfaction rate for pain relieve was 95.9% (47/49), and for functional recovery was 91.8% (45/49).

CONCLUSIONSMost 2-part surgical neck fractures, impacted 2-part greater tuberosity fractures and 4-part valgus-impaction fractures are good indications for percutaneous pinning. With appropriate and intense rehabilitation, satisfactory results can be expected in percutaneous pinning for the treatment of certain types of proximal humerus fractures.

OBJECTIVETo introduce the process and outline of fluoroscopy-based navigation system assisted anterior cruciate ligament (ACL) reconstruction, and evaluate its feasibility and accuracy.

METHODSFrom September 2005 to February 2006, there were 30 cases ACL rupture patients who received fluoroscopy-based navigation system assisted arthroscopy operations for ACL reconstruction (navigation group). At the same time, there were 40 patients who underwent traditional ACL operation (traditional group). For the navigation group, the proper placement of femoral and tibial tunnels was planned preoperatively in standard AP and lateral X-ray view. Intraoperative fluoroscopic images were taken and input into navigation computer system to form the virtual interactive working fields. After placement and registration, signals from patient trackers, which fixed on the distal femur and tibia respectively, and tool trackers, which attached with ACL tibial and femoral guide, were captured by the optic navigation camera and the navigation computer system could pursue the real-time position of the ACL tools and projected into working field to help precise placement of femoral and tibial tunnels. Then results of two groups were observed and evaluated.

RESULTSFor navigation group, the mean time extension was 20 min. The tibial tunnel position was measured in all these cases. The tibial tunnel position of navigation group was 45.90% (SD 2.36%), and the traditional group was 41.05% (SD 6.01%). The difference was statistically significant (P < 0.05).

CONCLUSIONFluoroscopy-based navigation system assisted ACL reconstruction improves the accuracy and reproducibility of the tunnel placement.

OBJECTIVETo determine the relative resistance to HIV-1 infection of CD4 + T lymphocytes in HIV-exposed seronegative individuals (ESNs) in China.

METHODSHIV primary isolates were obtained from peripheral whole blood of HIV-infected persons. CD4 + T lymphocytes of Chinese ESNs were separated from peripheral blood mononuclear cells with magnetic cell sorting (MACS). The purified CD4 + T lymphocytes were cocultured with HIV primary isolates. The p24 level was detected and the culture medium was refreshed every 3 days within 2 weeks.

RESULTSFor M tropic HIV strains, p24 level was significantly lower in ESN group than in control group (P < 0.05); for some M tropic HIV strains, even no p24 replicated in ESN group. However, T tropic virus strains had no significant difference between these two groups (P > 0.05).

CONCLUSIONCD4 + T lymphocytes of Chinese ESNs may possess relative resistance to M tropic HIV strains, which may be one of the main influencing factors that result in ESN.

OBJECTIVETo ascertain whether other variations coexist with 1555(A--> G) mutation in the mitochondrial DNA and may aggravate the severity of hearing loss or increase the penetrance of 1555(A--> G) mutation in a large family with maternally inherited nonsyndromic deafness in Huaiyin, Jiangsu province.

METHODSPCR-restriction fragment length polymorphism (PCR-RFLP) was used to screen both the nt1555 and the nt7445 of the mitochondrial DNA from 27 maternal members in the core family; and then the mitochondrial genomes from two maternal members, and the 12S rRNA genes MTRNR1 and tRNA-Ser(UCN) gene MTTS1 from the others, were amplified by PCR-RFLP and were sequenced.

RESULTS1555(A--> G) mutation in the mitochondrial DNA was reverified to be one of the major factors which cause maternally inherited nonsyndromic deafness and the cosegregation of 955-960(insC) and 1555(A--> G) was present in this family. Moreover, 7449 (insG), a novel homoplasmic mutation in the tRNA-Ser(UCN) gene, was found to co-exist with 1555(A--> G) mutation in two maternal members.

CONCLUSIONThe cosegregation of 955-960(insC) and 1555(A--> G) implies that 955-960(insC) may synergistically cause hearing loss in the presence of an 1555(A--> G) mutation, serving as an aggravating factor to enhance the sensitivity to aminoglycosides, and may sometimes increase the penetrance of 1555(A--> G) mutation.

OBJECTIVETo investigate the role of CD4+ CD25+ regulatory T (Treg) cells in patients with ITP.

METHODSFlow cytometry was used to examine the number of CD4+ CD25+, CD4+ CD25 high, CD4+ Foxp3+ and CD4+ CD25+ Foxp3+ T cells. The level of Foxp3 mRNA expression was analyzed by realtime quantitative reverse transcriptase polymerase chain reaction (RT-PCR) . CD4+ CD25 high T cells was cocultured with CD4+ CD25 - T cells from patients or controls for assessing the regulatory properties of CD4+ CD25 Treg cells.

RESULTSThe proportion of CD4+ CD25+ T cells in the peripheral blood of patients with ITP [(15.64 +/- 5.82) %] was significantly higher than that in normal control group [(9.30 +/- 3.95)%] (P <0.01). There was no significant difference in the percentages of CD4+ CD25 high T cells between ITP patients and controls [(1.53 +/- 0.66)% versus (1.36 +/- 0.55)% (P = 0.317)]. But the number of CD4 Foxp 3+ T cells and CD4 + CD25+ Foxp3+ T cells in patients were significantly lower than that in control group (P <0.01). The expression of Foxp3 mRNA reduced (P < 0.01) and the suppressive activity of CD4+ CD25 high T cells is lower than that of healthy controls (P <0.01).

CONCLUSIONIn patients with ITP, both the number and immuno-regulative function of CD4+ CD25+ Treg cells are reduced.
