Objective: To observe and evaluate the clinical efficacy and safety of using pediatric Tuina (Chinese therapeutic massage), Tui-Pushing chest-back manipulation, in treating children with cough variant asthma (CVA).Methods: Seventy-two kids with CVA were divided into two groups using the random number table method, with 36 cases in each group. The control group received the conventional Tuina treatment, and the observation group received additional Tui-Pushing chest-back manipulation. The clinical efficacy and adverse reactions were observed and recorded for the two groups. Results: After three treatment courses, compared with the control group, the observation group showed advantages in the total effective rate, reducing the number and intensity of cough and improving the nature of cough (P<0.05). However, at the one-month follow-up, there were no significant differences between the two groups in these parameters (P>0.05). Regarding the adverse reaction rate, there was no significant between-group difference (P>0.05). Conclusion: It is effective and safe to use pediatric Tuina, Tui-Pushing chest-back manipulation, plus the conventional treatment protocol to treat CVA in children.

Objective: To determine the optimal manipulation parameters in Liu's back tuina therapy for remission-stage cough variant asthma (CVA) in kids. Methods: A 5-factor 3-level L18(37) orthogonal design was adopted. The experimental factors and levels were selected: A, the number of times of Rou-kneading Feishu (BL 13); B, the frequency of Rou-kneading Feishu (BL 13); C, the number of times of Tui-pushing in a '介'-like pattern; D, the frequency of Tui-pushing in a '介'-like pattern; E, the intensity of red color after Ca-scrubbing Feishu (BL 13) with salt. A1, A2 and A3 stood for 10 times, 20 times and 30 times, respectively; B1, B2 and B3 stood for 200 times/min, 240 times/min and 280 times/min, respectively; C1, C2 and C3 stood for 50 times, 75 times and 100 times, respectively; D1, D2 and D3 stood for 150 times/min, 175 times/min and 200 times/min, respectively; E1, E2 and E3 stood for pinkish, bright red and dark red, respectively. A total of 108 kids with CVA in remission stage were divided into 18 groups using the random number table method, with 6 cases in each group. Changes in the cough score and fractional exhaled nitric oxide (FENO) level were observed after 15-day treatment. Results: The cough score and FENO level changed significantly in every group after treatment (all P<0.01). By the effect in improving cough score, the factors were listed as D, B, A, C and E in descending order; the most optimal manipulation parameter combination was group 17 (A3B2C1D3E1); the second optimal parameter combinations were group 7 (A3B1C2D1E3), group 13 (A2B1C2D3E1) and group 14 (A2B2C3D1E2). Regarding the effect in down-regulating the level of FENO, the factors were listed as C, A, E, B and D in descending order; the most optimal manipulation parameter combination was group 13 (A2B1C2D3E1); the second optimal parameter combinations were group 18 (A3B3C2D1E2), group 16 (A3B1C3D2E3) and group 14 (A2B2C3D1E2).Conclusion: Two most effective manipulation parameter combinations were selected out of 18 different parameter combinations in Liu's back tuina therapy for remission-stage CVA in kids. Doctors can choose an appropriate manipulation based on the symptom features of the disease.

Objective To explore the clinical value of dual-energy CT lung perfusion imaging and perfusion scintigraphy in acute pulmonary embolism (PE) rabbit models. Methods Acute PE models were established in 20 rabbits with femoral vein injection of sponge as embolus materials, and 4 rabbits were injected saline as control group. Two hours after embolization, dual-energy CT and perfusion scintigraphy imaging were performed respectively. Taking the pathologicall findings as the reference standards, the sensitivity, specificity, positive predictive value (PPV) and negative predictive value (NPV) of both imaging methods were compared. CT values and enhancement degree (overlay value) of the embolic areas and normal pulmonary parenchyma were measured in DEPI image after embolization. Results Normal lung was color-coded as homogeneously yellowish red, perfusion scintigraphy displayed rarefaction or absence. The sensitivity, specificity, PPV, NPV of DEPI was 100%, 97.50%, 95.24%, 100%, and of perfusion scintigraphy was 67.50%, 81.25%, 64.29%, 83.33%, respectively. Increased CT values and overlay values of embolism areas in DEPI images were lower than those of normal pulmonary parenchyma (P<0.05). Conclusion DEPI has higher sensitivity and specificity than perfusion scintigraphy for detection of pulmonary emboli in an acute PE rabbit models.

In order to establish the optimum condition for purifica tion of the nucleoprotein(NP) of rabies virus by immunoaffinity chromatography, the efficient and non-denaturative eluents(Mg-el) was obtained by using ELISA elution model; furthermore, it didn't damage the activity of NP. Two kind of NPs , expressed by recombinant vaccinia virus (rVac-N) and recombinant baculovirus (BRN), were purified by a Sepharose CL 4B column and a 2C12- Sepharose 4B colum n. By Western-blot and SDS-PAGE, high purity and good antigenical intact NPs w ere identified. The purified ribonucleoprotein (RNP) of rabies virus 5aG strain was also obtained. After immunized with NP and RNP, mice developed a strong anti -nucleoprotein response and were protected against a lethal challenge of rabies virus CVS strain. There were not difference been observed among the mice immuni zed with different purified protein. These data indicate that the NPs are antige nical and immunogenical comparable to the authentic rabies RNP and therefore pre sent a potential source of an effective ,safe and economical subunit vaccine.

Objective To study the levothyroxine doses and related factors in the treatment of pregnant women with subclinical hypothyroidism (SCH).Methods Fifty-six pregnant women with SCH (diagnosed before 12 weeks of gestation) were recruited and divided into 2 groups according to the baseline TSH levels,SCH group 1 (2.5 mIU/L ≤ TSH ≤ 5.0 mIU/L,n =24) and SCH group 2 (TSH＞5.0 mIU/L,n =32).Thyroid autoantibodies [thyroid peroxidase antibody(TPOAb) and thyroglobulin antibody(TGAb)] were detected.All the subjects were treated with levothyroxine and the doses were adjusted according to the TSH level.The therapeutic target was to keep the TSH levels under control,0.3 to 2.5 mIU/L for the first trimester and 0.3 to 3.0 mIU/L for the second and third trimesters.Results There was a positive correlation between the levothyroxine doses and baseline TSH levels (r =0.533,P＜0.01) in pregnant women with SCH.A significant difference in the levothyroxine doses between SCH group 1 and SCH group 2 was found [(0.583 ± 0.341) vs (0.961 ± 0.405) μg/kg,t =-3.695,P＜ 0.01].The levothyroxine doses in SCH group 2 were 64.84％ higher than those in group 1.There was a significant difference in the levothyroxine doses between thyroid autoantibody negative and positive subjects [(0.680 ± 0.370) vs (0.918 ±0.440) μg/kg,t =-2.197,P =0.032].The levothyroxine doses in thyroid autoantibody positive subjects were 35 ％ higher than those in the negative subjects.In addition,there was a significant difference in the levothyroxine doses between subjects with negative and positive thyroid autoantibody [(0.421 ± 0.192) vs (0.720 ± 0.385)μg/kg,t =-2.331,P =0.029] in SCH group 1.While in SCH group 2,the difference did not reach statistical significance.Conclusion The baseline TSH levels and status of thyroid autoantibodies may affect the levothyroxine dosage in pregnant women with SCH.

?AlM: To analyze and study the changes of intraocular pressure ( lOP) , visual field and P-ERG on patients with big cup/disk (C/D) in 24h.
?METHODS: A total of 120 cases ( 240 eyes ) diagnosed with big C/D (C/D>0. 3) were divided into group A (C/D<0. 6, 67 cases, 114 eyes ) and group B ( C/D≥0. 6, 73 cases, 126 eyes). Forty cases (80 eyes) with small C/D (C/D≤0. 3) were chosen as control group. All cases underwent 24h lOP examination, vision examination of 30-2 SlTA - standard static threshold and pattern electroretinogram ( P-ERG) examination. The differences between the examination indexes of the three groups were analyzed.
?RESULTS:There was no significant statistical difference in the 24h average lOP (P>0. 05) among the three groups, while the amplitudes had significant statistical differences (P<0. 05). Compared with the control group, the lOP amplitudes of group B were obviously higher, and the difference was of statistical significance (P<0. 05). ln terms of static threshold visual fields, the mean deviations (MD) and pattern standard deviations (PSD) of the three groups had significant statistical differences ( P < 0. 05 ). Comparison between every two groups:compared with the control group, the MD and the PSD were significantly increased in group B, and the difference was of statistical significance (P<0. 05); while there was no significant statistical difference in group A (P>0. 05);Compared with group A, the MD and the PSD were significantly higher in group B, and the difference was of statistical significance (P<0. 05). ln terms of P-ERG examination, there was no significant statistical difference in P50’s latent periods among the three groups (P>0. 05), but there were significant statistical differences in amplitudes (P<0. 05). Comparison between every two groups: compared with the control group, the P50’s amplitude was significantly decreased in group B, and the difference was of statistical significance (P<0. 05), while there was no significant statistical difference in group A (P>0. 05); Compared with group A, the P50’s amplitude of group B was significantly lower, and the difference was of statistical significance (P<0. 05).
?CONCLUSlON: When the patients’ C/D is no less than 0. 6, there are obvious changes of 24h lOP, static threshold visual field and P-ERG’s P50 wave. For patients with big C/D, a single lOP examination is far from sufficient, so an in-depth visual function examination should be performed. Meanwhile, it’s feasible to regard C/D 0. 6 as a screening criterion for suspected glaucoma.

Objective To study the effect of traditional Chinese medicine on survival time in children solid tumors with chemotherapy. Methods 76 children with solid tumors, which were collected from January 2005 to March 2006, were randomly divided into treatment group (35 cases), control group (41 cases). The treatment group was treated with chemotherapy + self-dispensing Fuzheng Jianpi Chinese medicine. The control group was treated with chemotherapy alone. Results The survival rate of the treatment group was higher than that of the control group, the difference was statistically significant (P = 0.0024). The average survival time after chemotherapy in the treatment group was (31± 2) months (95 % CI 27-34 months), the control group was (21±2) months (95 % CI 16-25 months), which was shorter than the treatment group.Conclusion Chinese medicine and chemotherapy can prolong the survival time of children with solid tumors.

Based on the idea that the pathogenic-etiologic mechanism is the " blockadeof liver channels, blood stasis and Qi stagnation resulting in malnutrition of liver due to iack of blood supply", the treating principle of " e-liminating stasis and supporting body resistance" was established with the combined use of extracts from peach -kernel plus cordicep hypha. 6 cases were thus treated. All of them received laparoscopy , and liver biopsy before and after the treatment. The gross appearance, histology and ultra. - microscopic structure and irnmuno - histo - chemistry were examined. Results showed that most of the activatedfat - storage cells after treatment were silent the I, III types of collagen depo - sited among the spaces of peri - sinusoid and liver cells and FN, LM weredecreased in part of the patient, resulting in less intrahepatic fibrosis, degradation of collagen fibres deposited in inter hepatic cellular spaces, inhibition and reversion of capillariza-tion oi liver sinusoid, hence, improvement of degener-ation of liver cells in most cases. The texture of the liver were turning normal with amelioration of portal hypertension and decrease of varicose mesenteric ves-seis. The liver turned red, swelling of falciform lig(?)-ment disappeared, and ascitis subsided.

Objective To evaluate the safety of surgical procedures for patients after heart valve prosthesis implantation.Methods Clinical data of 12 cases with heart valve prosthesis implantation undergone other surgical treatment from November 1996 to December 2005 were retrospectively analyzed.All the cases had routine oral warfarin with prothrombin time (PT) of 20.0—28.3 s averaged 23.5 s, international normalized ratio (INR) for prothrombin of 1.79—2.23 averaged 1.95 and heart functional class Ⅰ—Ⅲ.Among them,appendectomy was performed in three cases with acute appendicitis,reposition and repair in one with inguinal hernia,radical gastrectomy in two with gastric carcinoma,left hemicolectomy in one,cholecystectomy in three,left femoral head replacement in one,and bilateral high ligation and ablation of great saphenous vein in one.Elective surgical operation was performed in seven cases,and emergency operation in five.In those with elective surgery,warfarin was stopped 2—3 days before operation,while 5—10 mg vitamin K_1 was injected intramuscularly 6—8 hours before emergency surgery with preoperative median PT of 15.1 and 15.3 s and median INR of 1.24 and 1.30,respectively.In operation,5—10 mg vitamin K_1 were injected intravenously into the patients by drip depending on their bleeding on the surface of wound.ECG,blood pressure,hemoglobin and oxygen saturation were routinely monitored for all the cases intraoperatively and postoperatively.For the cases with heart function above class Ⅱ,fluid infusion was adjusted based on intubated central venous pressure,and for those with general anesthesia,analyses of blood gases and electrolyte were monitored routinely in operation.Results OPeration time averaged 20—160 rain in all the 12 patients,with blood loss 5—280 ml in average and without complications of massive hemorrhage,thrombosis and heart failure.Conclusions Surgical operation was safe for patients with heart valve prosthesis implantation,if preoperative PT and INR were adjusted to about 15 s and 1.30,respectively by cessation of warfarin or application of vitamin K_1,combined with careful manipulation and strengthened perioperative management.
