Objective To observe the different effects of iodine excess on inducing two strain mice thyroiditis. Methods NOD and Balb/c mice, each having 14 mice, were divided into NaI and control group. The mice were given 0.05% NaI water for 8 weeks in NaI group. RIA and ELISA were used respectively to detect TT4, TgAb, TPOAb and TSH level in serum. Morphology changes of thyroid and apoptosis of thyrocytes stained by immunohistochemistry were observed under light microscope. Lymphocytic proliferation of cervical lymph node and spleen to responding to Tg were detected by MTr method. Results After intake of iodine water for 8 weeks, NOD and Balb/c mice showed relative quality of thyroid in Nal group[(104.83±14.52), (155.79±20.77)mg/kg]obviously increased compared with control group[(71.80±20.42), (105.15±21.98)mg/kg, t values:-3.293,-4.429, all P< 0.01)], enlarged follicular lumen with colloid accumulation were observed in thyroid. Serum level of TT4 in Nal group [(29.52±4.42), (19.53± 2.35)nmol/L]to control group[33.40±5.38), (23.47±6.22)nmol/L]of NOD and Balb/c mice showed a decreasing tendency(t values: 1.374,1.567, all P > 0.05). TSH of Nal group showed an increasing tendency in Balb/c mice[(4.14±1.71)μg/L, compared with control [(3.55±1.41)μg/L, t values:-0.705, P > 0.05]and obviously increased in NOD mice [(6.98±0.66)μg/L, compared with control[(555±056)μg/L, t values:-3.562, P< 0.01], but no change of TgAb and TPOAb level in Nal group(1281,1364 cpm, 2.50×103, 0.14×103U/L were observed, compared with control(1297,1220 cpm, 3.17×103,0.03×103 U/L; Zvalues:-0.081,-0.703, -0.244,-1.293, all P > 0.05). In NOD mice NaI group, apoptosis of thyrocytes was more intense than Balb/c mice, obvious infiltration of lymphoeytes, disorganization and focus fibrosis was seen in thyroid. The cell amount of NaI group increased in NOD mice lymph node and spleen cells[(1.100±0.014), (1.076±0.033)]were more than that in the control group [(0.993±0.011), (1.005±0.003), t value:-11.672,-4.314, P < 0.01). Conclusions Iodine leads to enlargement of thyroid and malfunction of thyroid in Balb/c mice. Besides, NOD mice have generate inflammatory reaction in thyroid and produced sensitized lymphocytes to Tg. Iodine excess can induce NOD mice to occur autoimmune thyroiditis.

OBJECTIVETo study the clinical features, treatment and diagnosis of parapelvic cyst.

METHODSTwenty-three patients of parapelvic cyst of the kidney were reviewed retrospectively. Fourteen cases (61%) complained of lumbar pain or discomfort, and 4 patients (17%) accompany hematuria and hypertension.

RESULTSIn 15 patients receiving surgery, 2 were treated by nephrectomy, one by radical nephrectomy for misdiagnosis. Postoperative diagnosis confirmed a cyst. Eight patients were treated conservatively for cyst being small and without clinical symptoms. Nineteen cases were followed up for 0.5 - 12.0 years.

CONCLUSIONSUltrasonography and CT scan are the main diagnostic methods. Enhanced CT is extremely helpful in differential diagnosis of hydronephrosis. Surgical management is suitable for big cysts, lumbar pain, hematuria, hypertension and other complications.

Objective To explore the clinical features,diagnosi s and prognosis of incontinentia pigmenti.Methods Analyzing and summarizing the clinical characteristic, diagnosis and prognosis of neonatal incontinentia pigmenti in 6 neonatal infants that were hospita- lized in our department during the period from January 1 998 to December 2003 were studied,and some relevant literature were reviewed. Results 1.Three of 6 infants were male which was unusual;2.Four infants had typical skin lesions at birth and 1 case at 6 days old.Four cases had typical 3 stages o f skin lesions including the erythematous and vesicular inflammatory stage,verr ucous lesions and hyperkeratosis stage,macular hyperpigmentation stage,but the re was overlap;3.Four infants were complicated by central nervous system involv ement (two cases presented mental retardation,2 infants were temporary damage). Two cases were complicated by ocular manifestations ( one case had optical nerve atrophy and blind in left eye,the other had severe bilateral retinal lesions); 4.On specific examination 5 infants were diagnosed by skin biopsy.Gene analysis was made in 1 case,but we didn′t find the mutations of NEMO. Conclusions Incontinentia pigmenti is a rare X-linked dominant multisystem disease.It may be misdiagnosed in the initial stages.Except typical clinical features,skin biops y and gene analysis are main evidence for diagnosis.Early detection and interven tion are important for prognosis.

Objective To improve the recognition of intramedullary spinal abscess by a case of congenital dermal sinus with intramedullary spinal abscess and reduco the incidence of congenital dermal sinus with intramedullary spinal abscess.Methods Clinical,laboratory data and image of a confirmed case about one infant of congenital dermal sinus with multiple intramedullary spinal abscess were investigated,the related literature was reviewed.Results In this case,when the infant with congential dermal sinus had infection,he failed to gain antibiotic therapy, timely surgical treatment,his infection had diffused, and multiple intramedullary spinal abscess flared up.Conclusions Intramedullary spinal abscess is a rare disease.If treatment is delayed, the prognosis is poor and the mortality rate is high.MRI is the ideal investigation for diagnosis.Intramedullary spinal abscess can happen subsequent to congenital dermal sinus with infection, and cause neurological sequela. So an infant with congenital dermal sinus should be offered to avoid complication caused by infection.

Objective To determine if pregnancy affects the toxicity of bupivacaine and to investigate the effect of Shenfu injectio,a preparation of Chinese herbal medicine,on central nervous system and cardiac toxicity of bupivacaine in pregnant rats.Methods Twenty-four SD rats weighing 320-360 g were assigned to 3 groups(n =8 each):Ⅰ non-pregnant control group,Ⅱ pregnant control group and Ⅲ Shenfu injectio pretreatment group. The animals were anesthetized with isoflorane(2%-4%)-O_2 inhalation which was stopped before bupivacaine infusion was started.Femoral artery was canunlated for MAP monitoring and blood sampling and femoral vein was cannulated for bupivacaine infusion.MAP,HR and ECG were continuously monitored.All animals in the 3 groups received continuous infusion of 5% bupivacaine at 2 mg?kg~(-1).min~(-1).In group Ⅲ Shenfu injectio 10 ml?kg~(-1) was injected intraperitoneally(IP)30 min before bupivacaine infusion whereas in the two control groups(group Ⅰ and Ⅱ)equal volume of normal saline was injected IP instead of Shenfu injectio.The duration between the beginning of bupivacaine infusion and onset of convulsion/arrhythmia(QRS≥90 ms)/asystol was recorded and the amount of bupivacaine infused was calculated.Results There was no significant difference in the amount of bupivacaine causing convulsion and asystol between group Ⅰ and Ⅱ but the amount of bupivacaine causing arrhythmia was significantly larger in group Ⅰ(non-pregnant) than in group Ⅱ(pregnant control group)(P＜0.05).The amount of bupivacaine causing convulsion,arrhythmia and asystole was significantly larger in Shenfu injectio pretreatment group(group Ⅲ)than in pregnant control group(group Ⅱ)(P＜0.05 or 0.01).Conclusion Bupivacaine- induced cardiotoxicity is increased in pregnant rats and Shenfu injectio pretreatment can reduce the systemic toxicity of bupivacaine in pregnant rats.

OBJECTIVETo study the effect of Shengji Huayu Recipe (SHR)on the expression of MMP-3 and TIMP-1 in the skin ulcer tissue of diabetic rats.

METHODSThe skin ulcer model was established in diabetic mice. Different compatibility proportions of SHR [the ratio of Shengji Recipe (SJR) to Huayu Recipe (HYR) = 2:1, 1:1, and 1:2, respectively] were used to intervene. The expression of MMP-3 protein in the skin ulcer of diabetic rats was detected by Western blot method,and TIMP-1 protein was detected by immunohistochemical assay.

RESULTSAt each time point, there was no statistical difference in the blood glucose level among groups (P > 0.05). But all of them increased significantly,when compared with those of the normal wound group (P < 0.01). As for the difference between after would area treatment and before would area treatment, better effect was obtained in the SHR No. 3 group and the normal ulcer group than in the diabetic ulcer model group (P < 0.05). Results of Western blot showed that the MMP-3 protein expression was higher in the SHR No. 2 group than in the SHR No.3 group (P < 0.05). Immunohistochemical results showed that TIMP-1 protein expression was lower in the SHR No. 2 group than in the SHR No. 3 group and the diabetic ulcer model group (P < 0.05). TIMP-1 protein expression was higherin the SHR No. 3 group than in the SHR No. 2 group (P < 0.01).

CONCLUSIONUsing SHR No.3 was conducive to the promotion of wound healing in early wound repair stage, and using SHR No. 2 might be conducive to inhibiting the formation of pathological scar.

3 mg/L was significantly worse than in those with hs-CRP≤3 mg/L (18.18%,5.45%;P=0.044,log-rank test). Higher hs-CRP concentration was an independent predictor of death or new vascular event(OR 3.609;95% CI 0.869—14.992;P=0.047).Conclusion Higher hs-CRP concentration in acute phase after ischemic stroke is an independent predictor of death or new vascular event in a year.

OBJECTIVETo observe the effects of acupuncture at "Feishu" (BL 13) and "Lingtai" (GV 10) on distribution taxis of paclitaxel in mice with lung cancer to discuss targeted relationship between acupoints and corresponding viscera.

METHODSAccording to randomized digital table, 315 SPF-grade BALB/C female mice were divided into 7 groups: blank group (group A), model group (group B), medication group (group C), acupuncture at non-acupoint group (group D), acupuncture at Feishu group (group E), acupuncture at Lingtai group (group F) and acupuncture at Feishu and Lingtai group (group G), 45 mice in each one. Except the blank group, the remaining groups were treated with N-nitroso-tris-chloroethyl urea (NTCU) to establish the model of squamous-cell carcinoma. After model establishment, group A, group B and group C were not treated with acupuncture; group A and group B were treated with intraperitoneal injection of 0.9% sodium chlorvde solution by 6 mL/kg while group C was treated with intraperitoneal injection of paclitaxel by 6 mL/kg. The group D, group E, group F and group G were treated with acupuncture at non-acupoint, "Feishu" (BL 13), "Lingtai" (GV 10) and "Feishu" (BL 13) plus "Lingtai" (GV 10), respectively, then were intraperitoneally injected with paclitaxel by 6 mL/kg. The treatment was all given once a day for continuous 10 days. 15 min, 30 min, 1 h, 2 h, 8 h, 12 h and 24 h after the treatments, 6 mice in each group were randomly selected and sacrificed to collect samples of lung, liver, spleen, kidney and heart, etc. High performance liquid chromatography was applied to measure the concentration of paclitaxel in each organ (lung, liver, spleen, kidney and heart) at different time points.

RESULTS(1) The content of paclitaxel in lung, kidney and heart reached the peak at 2 h, then decreased significantly in group C, group D, group E, group F and group G; the content of paclitaxel in spleen showed downtrend at each time point. The content of paclitaxel in liver reached the peak at 2 h in group C and group D; the content of paclitaxel reached the peak at 8 h in group E, group F and group G. (2) The content of paclitaxel in lung in group E and group G was higher than that in group C and group D at each time point (all P < 0.01); the content of paclitaxel in lung in group F was higher than that in group C (P < 0.01) and group D (P < 0.01) only at time point of 2 h. The content of paclitaxel in lung in group G was higher than that in group F at each time point (all P < 0.05). There was no statistical difference between group G and group E (all P > 0.05).

CONCLUSIONAcupuncture at "Feishu" (BL 13) and "Lingtai" (GV 10) could influ- ence the metabolism of paclitaxel in lung-cancer mice, leading to distribution change in each organ. As a result, it could cause targeting effects, which is more significant at "Feishu" (BL 13) and "Lingtai" (GV 10).
