Objective To study the effects of quantitative 24-hour urinary protein on the thyroid hormone levels in patients with severe preeclamp-sia,and clarify the impact of severe urinary protein on hypothyroid in severe preeclampsia patients. Methods A total of 166 patients with severe pre-eclampsia were recruited for the study and divided into mild proteinuria group(2.0-4.9 g/d),midrange group(5-10 g/d)and severe group(>10 g/d)according to the quantitative 24-hour urinary protein. 268 healthy female individuals with normal blood pressure and uric routine in the same stage of pregnancy and of the same age were selected into control group. Serum thyrotropin(TSH),free triiodothyronine(FT3)and free thyroxine (FT4)levels were determined by solid-phase chemiluminescent enzyme immunoassay method(CMIA). The thyroid peroxidase antibody(TPOAb) and thyroglobulin antibody(TGAb)concentration were detected by electrochemiluminescent assay(ECLIA). Results TSH levels were signifi-cantly higher in patients comparing to the control group(P<0.01). In addition,severe group showed higher TSH levels than mild group(P<0.01). FT4 and FT3 levels were obviously decreased with the progression of the disease(P<0.01 and P<0.05). The positive rate of TPOAb in mild group was significantly higher than that in moderate group(OR=9.8,P<0.05). There was no significant difference of the TGAb positive rate among three patient groups(P>0.05). The incidence of subclinical hypothyroidism and clinical hypothyroidism in severe group was significantly higher than that in mild group and in control group(OR=2.5,P<0.05 and OR=9.0,P<0.05;OR=8.0,P<0.01 and OR=43.4,P<0.01). Conclusion Our re-sults indicated that 24-hour urine protein in severe preeclampsia patients has extensive effects on thyroid hormones levels. With the increasing of quantitative 24-hour urinary protein,the level of TSH increased and the FT4 decreased. Thyroid autoantibody positiveness has extensive effects on 24- hour urine protein. Incidence of hypothyroid increased with the increase of quantitative 24-hour urinary protein. 24-hour urinary protein quantitative was a risk factor for hypothyroidism in severe preeclampsia patients. More attention should be paid to the monitoring of 24-hour urinary protein in se-vere preeclampsia patients.

Objective To study effects of different degree of hypothyroidism in severe preeclampsia (S-PE) pregnant women on renal function and the correlation between them.Methods 46 S-PE patients with subclinical hypothyroidism (SCH) registered for treatment in the Shengjing Hospital of China Medical University from May 2011 to March 2013 were selected into SCH group,and 23 S-PE with overt hypothyroidism (OH) were selected into OH group,and 109 S-PE with normal thyroid stimulating hormone (TSH) levels were selected into simple group.Thyroid hormone and kidney function tests were analyzed in pregnant women with S-PE.We made an analysis of the relative risk of the detection rate of abnormal renal function and also the relationship between the levels of thyroid hormone and serum uric acid,serum urea and creatinine in patients with S-PE.Results (1) In SCH group serum TSH was (6.1±3.2) mU/L,free triiodothyronine (FT3) was (4.0±0.6) pmol/L,free thyroxine (FT4) was (11.8± 1.5) pmol/L; in OH group serum TSH was (5.2± 1.3) mU/L,FT3 was (3.7±0.6) pmol/L,FT4 was (9.3±0.5) pmol/L; in simple S-PE group serum TSH was (1.9±0.8) mU/L,FT3 was (4.0±0.8) pmol/L and FT4 was (11.9±1.9) pmol/L.TSH in SCH group was significantly higher than that in simple S-PE group (P＞0.01),the difference of in SCH and OH group were not statistically significant (P＞0.05).The difference of FT3 in three groups were not statistically significant (P＜0.05) ;FT4 in OH group was significantly lower than thoes in SCH and simple groups (P＜0.05).(2)Serum uric acid,creatinine and urea levels in OH group was (436± 114),(75± 15) μmol/L and (6±3)mmol/L,in simple S-PE group they were (378± 114),(65 ±22) μmol/L and (5±3) mmol/L.In comparison,the differences was statistically significant(P＜0.05).The differences were not statistically significant in SCH and OH groups (P＞0.05).(3)The abnormal detection rate of uric acid was significantly higher in SCH than that in OH group [46％ (21/46) versus 22％ (5/23),OR=3.0,P＜0.05].The comparison of remaining index has no statistical significance(P＞0.05).(4)In SCH group there was a significant inverse correlation of serum FT3 with serum urea levels,serum creatinine and serum uric acid (r=-0.32,-0.58,-0.35,P＜0.05).There was not a correlation of serum TSH,FT4 with indicators of renal function (P＞0.05).In OH group there was a negative correlation between FT3 and serum creatinine concentrations (r=-0.40,P＜0.05).In OH group there was not a correlation of FT3 with serum uric acid and urea (P＞0.05).There was a positive correlation between TSH and serum creatinine in simple S-PE group (r=0.20,P=0.04).There was not a correlation between TSH and serum urea(r=0.04,P=0.65),and serum uric acid (r=0.12,P=0.20).Conclusions There was effect of different hypothyrosis state in pre-eclampsia patients on renal function.Serum uric acid,urea and creatinine concentrations in S-PE pregnant women with OH were significantly higher than those in simple S-PE group with normal TSH.There was a negative correlation between FT3 and serum creatinine in S-PE.Hence the thyroid function should be regularly monitored in S-PE patients to find damage of renal function and management hypothyrosis.

Objective To investigate the changes of quantitative parameters of dynamic enhanced CT in non-small cell lung cancer before and after targeted therapy,and compare them with the traditional evaluation criteria,in order to find the parameters which can be exploited for timely,objective evaluation of the effect of targeted therapy.Methods The study included 21 patients with targeted therapy who had received dynamic enhanced CT before and after treatment.Enhancement time-density curves were obtained based on the CT values of the lesion at individual time points,and the functional indices:peak height (PH),the time to peak height (Tp),the ratio of PH of the mass to aorta (M/A) and perfusion value were calculated.The effects of the treatment on these indices were evaluated and compared with the effect of the treatment on lesion diameter. Results Twenty-one patients had 33 rechecking results. There was a statistically significant agreement between lesion diameter-based treatment evaluation and perfusion-based treatment evaluation ( U =8.761,P ＜ 0.01 ). The perfusion value decreased in patients with disease regression[before treatment:(0.28 ±0.11 ) ml · min-1 · ml-1,after targeted therapy(0.18 ±0.09) ml ·min-1 · ml-1,t =- 3.2722,P =0.0042],but increased in patients with disease progression[before treatment(0.21 ±0.08) ml · min-1 · ml-1,after targeted therapy:(0.34 ±0.11 ) ml · min-1 · ml-1,t =2.6064,P =0.0403].Conclusions On dynamic enhanced CT in non-small cell lung cancer patients after targeted therapy,perfusion value changed in the same trend as the diameter of tumor.The effectiveness of targeted therapy may be evaluated by perfusion value changes.

Objective To investigate the spiral CT findings in hemopathic patients with druginduced pulmonary injury.Methods CT images obtained in 11patients with drug-induced pulmonary injury were retrospectively analyzed.Six patients had antineoplastic agent-induced pulmonary injury and 5 patients had non-neoplastic agent-induced pulmonary injury (immunosuppressor in 2 patients,antifungal in 2 patients,antineoplastic immunomodulators in 1 patient).CT findings were reviewed by a chest radiologist.Results All 11patients had parenchymal abnormalities on MSCT scans,including ground-glass opacities( n =8 ),consolidation( n =5 ),interlobular septal thickening( n =3 ) and focal fibrosis ( n =2 ).The abnormalities were bilateral and asymmetric in all patients.They were mainly in the peripheral lung regions in 6 patients,in the central lung regions in four,and irregularly located in one.The abnormalities involved mainly the lower lung zones in six patients,the upper lung zones in two,and all lung zones homogeneously in three.One patient had fluid in bilateral pleural cavities.Three patients were given the same agent once more after the imaging turned to normal,and they presented with same clinical symptoms and similar but more serious imaging findings.Conclusions Drug-induced pulmonary injury usually manifests as areas of ground-glass opacity and consolidation,which most commonly involves the peripheral lungs and lower lung zones.Drug-induced pulmonary injury shows reproducible but more serious lesions when the patient is given the same agent once more.

Objective To study the imaging features and possible aetiology of osteonecrosis in adults with acute leukemia.Methods Ten adult patients with acute leukemia for osteonecrosis were reviewed retrospectively.All the lesions were confirmed with MRI.Results Four patients with ALL had accepted chemotherapy contained corticosteroids,two of them were performed HSCT,and one patient suffered GVHD.Six patients with AML had accepted chemotherapy without steroids,five of them were performed HSCT,and four patients suffered GVHD.One patient with AML-M3 had accepted chemotherapy including four courses of ATRA.The mean time between diagnosis of osteonecrosis and leukemia was 25.1 months.Nine cases had multiple lesions,one case had single lesion.The lesions involved femurs,tibias,patellas,iliums,and lumbars.Plain radiographs in six patients can not detect any lesion.Circinal reaction ossification could be detected in CT images of four cases.All the cases had typical feature in MRI.Conclusions In adult leukemia patients,osteonecrosis is a complication after chemotherapy or HSCT.Steroids in chemotherapy protocols or treatment for GVHD,ATRA for APML,chemotherapy-induced direct cytotoxic effect or leukemia itself can be the possible risk factor.For the diagnosis,MRI is the most effective way,and CT features of osteonecrosis in leukemia patients are different from those in non-leukemia patients.

OBJECTIVETo explore the clinical characteristic of functional articulation disorders in children and provide more evidence for differential diagnosis and speech therapy.

METHODS172 children with functional articulation disorders were grouped by age. Children aged 4-5 years were assigned to one group, and those aged 6-10 years were to another group. Their phonological samples were collected and analyzed.

RESULTSIn the two groups, substitution and omission (deletion) were the mainly articulation errors in these children, dental consonants were the main wrong sounds, and bilabial and labio-dental were rarely wrong. In age 4-5 group, sequence according to the error frequency from the highest to lowest was dental, velar, lingual, apical, bilabial, and labio-dental. In age 6-10 group, the sequence was dental, lingual, apical, velar, bilabial, labio-dental. Lateral misarticulation and palatalized misarticulation occurred more often in age 6-10 group than age 4-5 group and were only found in lingual and dental consonants in two groups.

CONCLUSIONMisarticulation of functional articulation disorders mainly occurs in dental and rarely in bilabial and labio-dental. Substitution and omission are the most often occurred errors. Lateral misarticulation and palatalized misarticulation occur mainly in lingual and dental consonants.

AIMTo make approach to the relationship between the changes of free zinc and ischemic neuronal damage in hippocampus after forebrain ischemia/reperfusion.

METHODSThe models of forebrain ischemia/reperfusion were established in rats. The contents of free Zn2+ were measured by TSQ fluorescence method. The Zn2+ chelator (CaEDTA) was injected into lateral ventricles in order to evaluate the effect of free Zn2+ on ischemic neuronal damage.

RESULTS(1) Zn2+ fluorescence in the hilus of dentate gyrus, CA3 region and the stratum radiatum and stratum oriens of CA1 decreased slightly at forty-eight hours after reperfusion. From seventy-two hours to ninety-six hour after reperfusion, the decreased fluorescence gradually returned to the normal level, but some fluorescence dots were found in pyramidal neurons of CA1 and the hilus of dentate gyrus. Seven days after reperfusion, all the changes of the fluorescence almost recovered. (2) The cell membrane-impermeable Zn2+ chelator CaEDTA could reduce the intracellular concentration of free Zn2+ and reduced neuronal damage after forebrain ischemia/reperfusion.

CONCLUSION(1) The synaptic vesicle Zn2+ released and then translocated into postsynaptic neurons after forebrain ischemia/reperfusion and played a role in ischemic neuronal damage. (2) The cell membrane-impermeable chelator CaEDTA could provide neuroprotection.

OBJECTIVETo explore the better therapy in the treatment of ganglion.

METHODSNinety cases of ganglion were randomized into a two-way quintuple puncture group, a common quintuple puncture group and a fire needling group, 30 cases in each one. In the two-way quintuple puncture group, the "9-in-1" multiple penetrating needling technique was used. In the common quintuple puncture group, the traditional "5-in-1" multiple penetrating needling technique was applied. In the fire needling group, the traditional multiple fire needling technique was adopted. The treatment was given once a day, 3 treatments made one session and the efficacy was analyzed statistically after 1 session treatment in the three groups.

RESULTSAll of the three therapeutic methods achieved the efficacy on ganglion. The curative rate was 96. 7% (29/30) in the two-way quintuple puncture group, which was better obviously than 66.7% (20/30) in the common quintuple puncture group and 60. 0% (18/30) in the fire needling group (both P<0. 01).

CONCLUSIONThe two-way quintuple puncture technique achieves the remarkably superior efficacy on ganglion as compared with the common quintuple puncture technique and fire needling technique.

This study was purposed to explore the mechanisms of preventive effect of tetrandrine (TTD) on doxorubicin (ADM)-induced multidrug resistance (MDR) in human leukemia cell line K562 from two aspects of the transcription control of MDR1 gene and cell apoptosis. The experiment was divided into 3 groups: group I-blank control; group II-ADM-induced drug-resistance; group III-ADM-induced drug-resistance after pretreatment with TTD. Reverse transcription-PCR (RT-PCR) was used to detect the mRNA expression levels of c-Jun, YB-1 and Survivin genes. Western blot was used to determine the nuclear protein expression levels of c-Jun and YB-1. Flow cytometry was used to assay the apoptosis of cells. The results showed that as compared with group I, the expression levels of c-Jun mRNA and nuclear protein decreased (p < 0.05), as well as the expression levels of YB-1 mRNA and nuclear protein increased in group II (p < 0.05). However, the expression of Survivin mRNA had no change (p > 0.05); the apoptosis rate of cells was 8.31%. As compared with group II, the expression levels of c-Jun mRNA and nuclear protein increased (p < 0.05), expression levels of YB-1 mRNA and nuclear protein as well as Survivin mRNA decreased in group III (p < 0.05). The apoptosis of cells was 97.2%. It is concluded that TTD can inhibit the expression of YB-1 and up-regulate the expression of c-Jun, thus inhibit the expression of MDR1 gene. TTD can also inhibit the expression of Survivin and increase the apoptosis of cells induced by ADM.

OBJECTIVETo observe different effects of moxibustion on extracellular potassium ion in acupoint under physiological and pathological status and provide experimental evidence for exploring action mechanism of moxibustion on acupoint local.

METHODSForty female SD rats were randomly divided into a blank group, a blank-moxibustion group, a model group and a model-moxibustion group, 10 cases in each one. The complete Freund's adjuvant(CFA) was adopted to establish model of adjuvant arthritis (AA) in the model group and model-moxibustion group. No treatment was given in the blank group and model group while moxibustion was applied at "Zusan-li" (ST 36) for 30 min in the blank-moxibustion group and model-moxibustion group. The tissue fluid in "Zusanli" (ST 36) was collected with microdialysis and real-time analyzed by electrolytic analyzer. The change of concentration of potassium ion in "Zusanli" (ST 36) was observed.

RESULTS(1) Under physiological status, the concentration of extracellular potassium ion in the blank group was not changed within 150 min (P > 0.05); before the moxibustion, the concentration of extracellular potassium ion in the blank-moxibustion group was (1.21 +/- 0.31) mmol/L, and after treatment it was gradually increased and reached its peak at (2.38 +/- 0.42) mmol/L after 60 min (P < 0.05), then it was reduced. 150 min after the treatment, concentration of potassium ion was slightly higher than that before moxibustion as well as that in the blank group. The concentration in the blank-moxibustion group at 60 min was statistically significant compared with that in the blank group (P < 0.05). (2) Under pathological status, the concentration of extracellular potassium ion in the model group was not changed within 150 min, differences of which at each time point was not statistically significant (all P > 0.05). Before the moxibustion, the concentration of extracellular potassium ion was (1.09 +/- 0.12) mmol/L in the model-moxibustion group, and it was immediately increased to (1.96 +/- 0.18) mmol/L after moxibustion. 60 min and 90 min after the moxibustion, it still maintained a higher level, which was (1.87 +/- 0.29) mmol/L and (1.59 +/- 0.16) mmol/L respectively (both P < 0.05). The differences of each time point after moxibustion in the model-moxibustion group were statistically significant compared with those in the model group (all P < 0.05).

CONCLUSIONThe moxibustion could increase the concentration of potassium ion in rat's acupoint local under physiological status but time of effect is short; with moxibustion at "Zusanli" (ST 36) under pathological status, the concentration of local potassium ion is obviously increased and maintains for a long time.
