Soft tissue perineurioma is a very rare tumor composed of entirely of neoplastic perineurial cells. A 54-year-old woman presented with a palpable mass in the right lower leg. The mass was excised. Grossly, the tumor measured 2.0x2.0x1.5 cm. The cut surface was well circumscribed, pale pinkish gray, and rubbery soft. Histological examination showed that the tumor was composed of spindle cells within collagenous and myxoid stroma. The tumor cells had elongated, tapering nuclei with long and thin cytoplasmic processes, and were arranged in fascicular, whorled, and storiform pattern. The tumor cells were positive for epithelial membrane antigen and collagen type IV and negative for S-100 protein. Ultrastructurally, tumor cells showed long and thin cytoplasmic processes, pinocytic vesicles, and incomplete external lamina. The diagnosis of soft tissue perineurioma was confirmed by immunohistochemical stain and ultrastructural study.

The old flexor tendon injury in the hand seen after 4 weeks from damage and associated with crushing injury, heavy scarring, fracture and infectious state has the difficulty to deliver the flexor tendon through fibro-osseous sheath and the pulleys. Treatment method depends on the circumstances of the injured flexor tendon and surgeons' judgement. We have treated twenty-three fingers of twenty-three cases, who had old flexor tendon injury, by advancement and tenolysis in 1 each, tendon graft in 5, and staged tendon graft in 16 from March 1989 through February 1994. The result was summarized as follows. 1. The old flexor tendon injury most commonly occurred in the fifth finger(11 cases, 47.8%)and in zone II (16 cases, 69.6%). 2. The most common cause was glass injury(15 cases, 69.6%). 3. 21 of 23 cases(2 thumbs excepted)were evaluated according to the original Strickland system. 14 cases of the staged tendon graft showed excellent(6 cases, 42.9%), good(5 cases, 35.7%)and fair(3 cases, 21.4%). 5 cases of the tendon graft showed excellent(2 cases, 40%), good(1 case, 20%), and fair(2 cases, 40%). 1 case of adhesiolysis and 1 case of advancement showed excellent and good results each. Little difference is observed in the method between the staged graft and tendon graft. 4. The degree of the associated soft tissue injury should be evaluated by the experienced hand surgeon before surgery and the delicate balance between protection and mobilization during the postoperative weeks is important as well as the surgical skill.

Background and purpose:The skeleton is the most common site of tumor metastasis in lung cancer.Skeletal complications from bone metastasis,such as severe bone pain,functional impairment,may substantially reduce quality of life,in some situations,may result in death.We explored the efficacy of ibandronate combined with chemotherapy in treatment of lung cancer with bone metastasis.Methods:Sixty-four lung cancer patients with bone metastasis were randomized into two groups:38 patients in study group received normal chemotherapy combined with ibandronate,and 26 patients in control group received normal chemotherapy only.Results:The response rate of pain relief in the study group and control group was 71.1% and 42.3%,respectively(P=0.006).In study group,serum alkaline phosphatise and serum calcium was decreased after treatment by ibandronate combined with chemotherapy(P0.05).Conclusion:Ibandronate is safe and well tolerated. Ibandronate combined with chemotherapy is effective in relief of the pain caused by bone metastases and may inhibit bone metastasis.

Keratosis punctata of the palmar creases (KPPC) is rare skin condition characterized by punctiform hyperkeratotic pits confined to the palmar and digital creases. Although this condition has been regarded as a variant of classical punctate keratoses, there are some differences between classical punctate keratosis and KPPC. We herein report a case of KPPC in a 22-year-old man who had numerous, tiny, hyperkeratotic pits limited to the palmar creases of both hands with typical histologic findings.

BACKGROUND:Different mechanical stimulations may have an effect on the level of metabolism of chondrocytes, but the effect is not clear.
OBJECTIVE:To investigate expression level changes in metabolic genes that participate in cartilage cel decomposition and synthesis under compressive stress and tensile stress conditions.
METHODS:We obtained articular chondrocytes from 2-week-old Sprague-Dawley rats. Primary cultured chondrocytes were identified. Passage one chondrocytes received cyclic tensile stress and cyclic compressive stress of 3%and 7%, respectively, so as to measure articular changes in chondrocytes-related genes.
RESULTS AND CONCLUSION:When chondrocytes were subjected to cyclic tensile stress of 3%, synthetic metabolic gene col agen types I and II and proteoglycan mRNA expression levels were decreased. If 3%cyclic compressive stress was applied, proteoglycan mRNA expression levels were increased, and type I col agen mRNA expression levels were decreased (P<0.001), and matrix metal oproteinase-13 mRNA expression levels were reduced (P<0.01). When strain reached 7%, cyclic tensile stress and compressive stress could lead to a general decrease in anabolism-related genes. The former could also make matrix metal oproteinase-13 mRNA expression levels increased (P<0.05). 3%cyclic compression ratio and 3%cyclic stretch made cytoskeleton become oval. These results indicated that in vitro, proper cyclic compressive stress is beneficial to maintain the growth characteristics of articular chondrocytes in rats. Smal tensile stress can decrease the synthesis ability of chondrocytes. The effect of stress may be caused by changing the cytoskeleton.

ObjectiveTo explore the role of parameters of organ function during heat stroke (HS) on the prognosis, and to form the treatment strategy through an analysis of parameters of organ function during HS. Methods A retrospective study was conducted. Thirty-seven patients with HS (HS group) and 54 patients with mild-to-moderate stroke (stroke group) admitted to Zhejiang Xiaoshan Hospital from 2011 to 2014 were enrolled. The experimental results of organs function indicators for patients were recorded including:① cardiac markers:troponin I (TnI);② myocardium zymogram: creatine kinase (CK), MB isoenzyme of creatine kinase (CK-MB), lactate dehydrogenase (LDH), and aspartate aminotransferase (AST);③ renal function indexes: blood urea nitrogen (BUN), uric acid (UA), and serum creatinine (SCr);④ electrolyte: serum K+, Na+, and Cl-;⑤coagulation function: prothrombin time (PT), international normalized ratio (INR), activated partial thromboplastin time (APTT), thrombin time (TT), fibrinogen (FIB), and D-dimer;⑥ blood gas analysis: pH value, arterial partial pressure of carbon dioxide (PaCO2), base excess (BE), standard bicarbonate (SB), and actual bicarbonate (AB);⑦ routine blood test: blood platelet count (PLT);⑧ hepatic function: alanine aminotransferase (ALT). Abnormal rates of laboratory parameters of 37 HS patients were statistically analyzed. Various laboratory parameters of organs function as well as the initial value and extreme value (maximum or minimum value) during treatment of CK and PLT in HS patients were compared between two groups.Results The abnormal rates of 37 HS patients were more than 70%, including incipient value of TnI, CK, LDH, AST, serum Na+, ALT, D-dimer, PaCO2, AB, maximum value of CK, and minimum value of PLT, the abnormal rates being 73.0%, 70.3%, 81.1%, 78.4%, 78.4%, 70.3%, 70.3%, 70.3%, 75.7%, 81.1%, 75.7%, respectively. The abnormal rates of other parameters were less than 70%. There were significant differences in incipient value of TnI, CK, LDH, AST, serum K+, serum Na+, D-dimer, and PLT between HS group and mild-to-moderate stroke group [TnI (μg/L): 0.087 (0.026, 0.306) vs. 0.007 (0.004, 0.110),Z = -7.017,P = 0.000;CK (U/L): 392.30 (287.60, 524.10) vs. 137.10 (106.33, 607.80),Z = -7.930,P = 0.000; LDH (U/L): 317.98±122.74 vs. 207.85±57.71, t = 1.678,P = 0.000; AST (U/L): 94.90 (52.80, 155.80) vs. 26.10 (18.13, 317.40),Z = -6.157, P = 0.000; serum K+ (mmol/L): 3.46±0.65 vs. 3.86±0.57,t = 1.662,P = 0.001; serum Na+ (mmol/L): 129.75±7.34 vs. 138.79±4.26,t = 1.674,P = 0.000; D-dimer (mg/L): 2.53 (0.63, 6.00) vs. 0.30 (0.21, 9.71),Z = -5.084, P = 0.000; PLT (×109/L): 144.62±86.14 vs. 219.48±64.76,t = 1.669,P = 0.000]. There were also statistically significant differences in the initial value and extreme value of CK and PLT between HS group and mild-to-moderate stroke group [CK (U/L): 392.30 (287.60, 524.10) vs. 721.50 (546.30, 964.10),Z = -6.351,P = 0.000; PLT (×109/L):132.40±82.55 vs. 68.24±44.62,t = 1.688,P = 0.000].Conclusions HS can impair several organs and systems, having complications, and it is a heavy insult for body. Increasing of CK and decreasing of PLT has some value to assess illness changes. It is helpful of laboratory results for doctors to estimate complications on time.
