BACKGROUND:The incidence of femoral head necrosis after internalfixation in femoral neck fracture is at highlevel, but the risk factors are stil under discussion. OBJECTIVE:To retrospectively propose and analyze the relative risk factors of femoral head necrosis after internal fixationwithfemoral neck fracture in patients younger than60years old. METHODS:Data from199 patients with femoral neck fractures,younger than60years,undergoingclosed reduction and internal fixation were analyzed retrospectively.Seven factors including age, sex, body mass index, Garden classification, fracture seasons, reduction quality and weight-bearing time after internal fixation were statisticalyanalyzedto evaluate their correlation with femoral head necrosis. RESULTS AND CONCLUSION:The incidence of femoral head necrosis was 13.1%amongthe199 cases. Body mass index, Garden classification, fracture seasons, reduction quality were significantly associated with femoral head necrosis. The age, sex and weight-bearing time wereinsignificantly associated with femoral head necrosis. In multivariate logistic regression analysis, Garden classification, reduction quality and fracture seasons (winterversussummer) hadoverteffectson development of femoral head necrosis. These results suggest that Garden classification and reduction quality make an important effect on the healing of femoral neck fracture. In addition, fracture in winter may be the risk factor of the femoral head necrosis after internal fixation in femoral neck fracture.

Measurements of mitral flow velocity by pulsed Doppler echocardiography are very useful in evaluating left ventricular diastolic filling properties. In hypertensive patients, abnormalities of diastolic function may precede systolic abnormalities and may serve as a more sensitive marker of end organ damage. We estimated left ventricular nass by 2-D echo short axis area-length method and compared with peak mitral flow velocity in early diastole(PFVE)and during atrial systolic(PFVA). There was a significant increase of LV mass and LV mass indices in the hypertensive patients and PFVE/PFVA ratio was decreased in them. Aithough there was no relationship between blood pressure and PFVE/PFVA ratio, a significant relationship was demonstrated between LV mass index and PFVE/PFVA ratio in the hypertensive patients.

Twenty-nail dystrophy is an idiopathic nail dystrophy in which all twenty nails are uniformly and simultaneously affected with excess longitudinal ridging and loss of lustre. The pathogenesis is controversial, and the treatment is unsuccessful. It is thought to have a self-limiting and reversible nature when it develops in childhood, but in adults, it is unusual and exists persistently. We re-port here two cases of adult patients with dystrophy of all twenty nails, whose ages were 58 and 55. The disease had been present for one year and may be associated with alopecia areata in the 58 year old and an idiopathic condition in the 55 year old. Negative results were obtained on mycological studies. Biopsies taken from the nail bed revealed marked hyperkeratosis consistent with nail dystrophy.

OBJECTIVETo study the protective effect of Ligustrazine Injection (LI) against cisplatin-induced ototoxicity and to explore its mechanism.

METHODSThirty healthy adult guinea pigs were randomly divided into three groups, 10 in each group, i.e., the normal control group, the cisplatin group, and the LI group. Guinea pigs in the normal control group were intraperitoneally injected with normal saline at 3 mL/kg for 7 consecutive days. Those in the cisplatin group were intraperitoneally injected with cisplatin at 3 mg/kg for 7 consecutive days. Those in the LI group were intraperitoneally injected with LI at 140 mg/kg for 7 days, but cisplatin (3 mg/kg) was intraperitoneally injected from the opposite side starting from the 4th day. Brainstem auditory evoked potential (BAEP) was performed in all animals before and after injection. All animals were sacrificed after the final testing under anesthesia and their cochleas collected. Half the cochleas of each group were collected for silver nitrate staining of cochlear basilar membrane stretched. The other half the cochleas of each group made into paraffin sections to observe the apoptosis of cochlea cells by TUNEL method and the expression levels of c-Jun detected by immunohistochemistry.

RESULTSThere was no statistical difference in the difference of BAEP threshold among the 3 groups before injection (P > 0.05), but the BAEP threshold increased in the cisplatin group and the LI group (P < 0.05). Besides, it was higher in the cisplatin group (P < 0.05). In the cisplatin group, most hair cells were missing, spiral ganglion cells obviously decreased, more TUNEL positive cells occurred, and the expression of c-Jun was stronger. But the aforesaid impairment in the LI group was obviously lessened (P < 0.05).

CONCLUSIONSLI showed certain antagonist effect on cisplatin-induced ototoxicity. Its mechanism might be associated with scavenging oxygen radicals of the cochlea tissue, improving the microcirculation, and fighting against apoptosis.

A case of a 21-year old female with Maffucci's syndrome is presented where the patient developed multiple cutaneous spindle-cell hemangioendotheliomas. She had multiple pea to walnut sized, non-tender, normal skin colored or slight bluish nodules and bony mass-like lesions on the left upper extremity and hand. A histological examination of the lesions showed that they were composed of irregularly dilated, thin walled cavernous blood spaces containing phleboliths and collapsed vascular spaces separated by spindled fibroblastic cells. Radiologically, the bony lesions showed radiolucent densities with calcified spots within the second proximal phalanx and metacarpal bone of the left hand, which were consistent with enchondromas.

Of the 11 advanced bladder cancer patients who received M-VAC (Methotrexate, Vinblastine, Doxorubicin and Cisplatin) combination chemotherapy, complete and partial remission were observed in 63.6%. Of the 17 advanced bladder cancer patients who received MAC (Methotrexate, Doxorubicin and Cisplatin) combination chemotherapy, complete and partial remissions were observed in 17%. Complete remission was achieved in 18.2% of the patients clinically, pathologically in M-VAC group and 5.9% in MAC group. Partial remission was occurred in 46.5% of the patients in M-VAC group and 41.2% in MAC group. All metastatic sites including the bone and liver, lung were well responded in M-VAC group, but poorly responded in MAC group. Toxicity was significant but tolerable.
