50Gy gave better survivals.Conclusion Age,tumor histology,ex- tent of resection,interval time of postoperative radiotherapy and the dosage of target were related to survival.

ObjectiveTo investigate the effect of speech therapy on mental health of patients with aphasia. MethodsCRRCAE and SCL-90 were used to assess the speech and mental state in 28 aphasia patients. All aphasia patients were treated by using speech therapy and the changes before and after treatment were compared. ResultsThe scores in listening comprehension, repetition, naming, reading,reading comprehension, writing and counting were distinctly higher at post-treatment than that at pre-treatment. All SCL-90 factor's levels at post-treatment were distinctly reduced than that at preat post-treatment(P<0.01).Conclusions Speech therapy can improve the language function,as well as mitigate the mental symptoms.

AIMTo increase the cognition of cerebellar functions and the knowledge of neuroimmunology, the effect of cerebellar interposed nuclei (IN), one of three deep nuclei in cerebellum, on lymphocyte function was investigated.

METHODSKainic acid (KA) was microinjected into bilateral IN for lesions of neuronal bodies in the IN. Control rats was microinjected with saline into their IN. On days 8, 16 and 32 following the IN lesions, the lymphocyte number in the peripheral blood was measured by blood corpuscle counter. Meanwhile, lymphocyte proliferation induced by concanavalin A (Con A), cytotoxicity of natural killer (NK) cells against YAC-1 cells, and anti-SRBC IgM antibody in the serum were examined respectively by methyl-thiazole-tetrazolium (MTT) assay, flow cytometry and ELISA assay.

RESULTSThe lymphocyte number in the peripheral blood was significantly reduced on days 8, 16 and 32 following the effective lesions of the bilateral IN in comparison with that of control. The Con A-induced lymphocyte proliferation, the NK cell cytotoxicity to YAC-1 cells, and the titer of anti-SRBC IgM antibody in the serum, were all significantly attenuated on days 8, 16 and 32 following the effective lesions of the bilateral IN in comparison with those of control. There were not remarkable differences between the days 8, 16 and 32 in the decreased lymphocyte number and functions induced by the lesions of the bilateral IN.

CONCLUSIONEffective lesions of the cerebellar bilateral IN of rats cause an inhibition in lymphocyte number and functions of T, B and NK cells, strongly showing that the cerebellar IN can modulate lymphocyte functions.

Objective To analyze the ultrasonic features of thyroid microcarcinoma (TMC) and the causes of misdiagnosis. Methods The ultrasonic features including shape, margin, echogenecity, microcalcification, vascularity and lymphadenopathy were analyzed retrospectively in 26 pathologically-proven TMC patients. Results In 26 cases, 11 cases were diagnosed correctly before operation (11/26, 42.31%), 12 cases were misdiagnosed (12/26, 46.15%) as adenoma or benign nodule, and 3 cases were missed diagnosed (3/26, 11.54%). Among the 23 cases detected on ultrasound, 21 cases were solid and hypoechoic (21/23, 91.30%);19 cases were ill-defined (19/23, 82.61%);12 cases were taller than wide in shape (12/23, 52.17%); 14 cases had microcalcification (14/23, 60.87%); 7 cases showed central or peripheral blood flow signals (7/23,30.43%) with arterial resistance index>0.70 in 3 lesions and<0.70 in 4 lesions. Conclusions Several ultrasonographic features are helpful in identiifcation of TMC, including hypo/iso-echogenecity, ill-deifned margin, taller-than-wide shape, microcalciifcation, arterial signals with high resistance index, and abnormal lymphadenopathy. Moreover, for cases with multiple lesions, to the potential co-existence of benign and malignant lesions should be considered.

Objective To explore the roles of macrophage inflammatory protein-1?(MIP-1?)in hypoxic-ischemic encephalopathy(HIE)of newborn infarnts.Methods Serum samples were obtained in 24,72 h and 7 d after birth respectively from 34 newborn infants with HIE,and 20 newborn infants without HIE as control group.Enzyme-linked immunosorbent assay(ELISA)method was used to determine the serum concentrations of MIP-1?.Results Levels of MIP-1? in newborn infants with HIE [(12.47?2.51)ng/L]were significantly higher than that of newborn infants without HIE [(8.63?2.63)ng/L](P0.05).Conclusions MIP-1? are involved in HIE of neonates,and the more severe damage,the higher levels in serum,which suggests that,as an inflammatory mediator,the MIP-1? may play an important role in involvement of brain hypoxic-ischemic damage.

Objective To investigate blood gas analysis and lactic acid evaluation in aerobic forearm exercise and the significance of aerobic forearm exercise for the auxiliary diagnosis of mitochondrial myopathy and encephalopathy patients.Methods Forty-two patients with mitochondrial myopathy and encephalopathy patients, 40 healthy control, and 40 patients control were studied.They performed a protocol under aerobic exercise conditions, consisting of intermittent forearm exercise for 4 minutes at 40% of intented maximal voluntary contraction force.Blood samples were collected to monitor blood gas and plasma lactate before, during arid after exercise.Results During exercise venous PO_2(mm Hg, 1 mm Hg=0.133 kPa)decreased in mitochondrial myopathy and encephalopathy patients from 41.2?12.6 to 39.5?16.2, whereas PO_2 fell from 50.5?14.4 to 30.8?13.1 in healthy control and from 50.1?7.9 to 44.3?35.5 in patient control.Venous PO_2 decreased much more in healthy control group than the other 2 groups(F= 6.34,P

OBJECTIVETo observe the synergic or antagonistic effect of needling acupoints Fengchi (GB 20) and Tianzhu (BL 10), and Jiaji C4-C6 (EX-B2) on vertebro-basilar insufficiency (VBI).

METHODSSelf-control method was used and 20 cases of VBI were respectively treated with acupuncture at Fengchi (GB 20) and Tianzhu (BL 10), Jiaji (EX-B2). Their combination and the changes of vertebro-basilar artery's (VBA) systolic velocity of blood flow was detected.

RESULTSThe VBA's systolic velocity of blood flow after acupuncture were increased in all the 3 groups (P < 0.05 or P < 0.01), with no significant difference among the 3 groups (P > 0.05).

CONCLUSIONAcupuncture at Fengchi (GB 20) and Tianzhu (BL 10) or Jiaji (C4-C6 ) or their combination can increase VBA's systolic velocity of blood flow, improving blood supply of vertebro-basilar artery, but they have no synergic or antagonistic effects.
