Objective To investigate effects of multimodal analgesia on cytokines and cortisol levels in patients received surgical treatment for radical colon cancer.Methods Eighty-six patients with radical colon cancer treated with surgery were randomly divided into control group and observation group.The control group only received routine epidural anesthesia and the observation group received multimodal analgesia.Preoperative and postoperative VAS scores,cytokines and cortisol levels were measured.Results Compared with those of the control group,the following 5 indicators decreased significantly in the observation group including VAS scores of after 24 h,48 h,72 h,IL-8 and TNF-α after 24 h,IL-6,IL-8 and TNF-α after 48 h,Cor after 24h,and Cor and ACTH after 48 h (P＜0.05).Conclusion Perioperative multi-mode analgesia helps relieve pain,stress and inflammatory cytokines among patients after the surgery for radical colon cancer.

Objective To develop two-grille latrines with the effect of non-hazardous treatment. Methods According to the result of the pretest, one type of two-grille latrines was selected and constructed and its effect of non-hazardous treatment was evaluated. Results The faces-treatment pool, with cement-prefab structure and obturation, had a total cubage of 1.32 m3. The average total amount of faces in the pool was 1.05 m3 per family per month, and the pool could store the faces for over 34 days. The “reaching criteria rate” of the parasite ova sediment and the value of the fecal coliform bacteria were 100% among the excrement in the outlet. Conclusions The prefab two-grille latrines can reach the criteria of non-hazardous treatment, and they can be used in well-off rural areas without the usage of manure.

In order to make sure whether Panax notoginseng is sensitive to chloridion and guide fertilization in planting of P. notoginseng, the effects of the different proportion of potassium chloride (KCl) and potassium sulfate (K2SO4) on the yield, quality of P. notoginseng were studied. The results showed that K fertilizer significantly improved the growth of P. notoginseng and increased the biomass per plant or per pot and the content of N, P, K and the content of saponin. In cases of conditions such as potassium, and the effects of K2SO4 on increasing the petiole length, leaf size, rhizome length, root length, and content and accumulation of Ginsenoside Rg1 were better than those of KCl. While compared with K2SO4, KCl was more conducive to augmenting height, root width, the biomass of shoot, rhizome, root and the content of Ginsenoside Rb1 and Rd. There was not remarkable difference in agronomic characters, biomass and the content of N, P, K among KCl, K2SO4 and the combination of KCl and K2SO4. However, the content of saponin of the treatment with combination of KCl and K2SO4 was significant higher than that of single KCl or K2SO4 treatments. K fertilizer significantly increased yield and the content of saponins. And P. notoginseng was not sensitive to chloridion. KCl increased the yield and the content of saponins of P. notoginseng as well as K2SO4, and the combination treatment was superior to single treatment. It is recommended that the KCl should be adopted in production, to reduce the cost of potash fertilizer.

OBJECTIVE: To study the assessed value of 64 slice spiral CT perfusion imaging (CTPI) in laryngeal squamous cell carcinoma after chemotherapy and radiotherapy. METHOD: Forty five patients diagnosed with local advanced laryngeal squamous cell carcinoma were selected. Conventional CT and CTPI were performed before treatment and at the time of radiation dose up to 40 Gy. Blood flow, blood volume, mean transit time and surface permeability were measured at the same time. According to the decrease of tumor volume in final examination, patients were divided into sensitive group and insensitive group. The tumor perfusion indexes were compared between groups. RESULT: Blood flow, blood volume, surface permeability after 40Gy treatment were lower than before treatment in both sensitive group and the insensitive group ascended(P<0. 05). The AUC of ROC of blood flow, blood volume, mean transit time and surface permeability were 0. 804, 0. 843, 0. 852 and 0. 826. The sensitivity, specificity and accuracy of blood flow was 89. 7%, 86.8% and 90. 9%. There were 100. 0%, 91. 4% and 93. 7% in blood volume; 100. 0%, 67. 7% and 88. 3% in mean transit time; 91. 2%, 69. 4% and 90. 6% in surface permeability(P<0. 01). CONCLUSION Sixty-four slice spiral CT perfusion imaging is able to assess tumor status of laryngeal squamous cell carcinoma after chemotherapy and radiotherapy effectively.

PurposeTo evaluate the significance of ultrasonic elastography strain ratio, MRI and the combination of both in diagnosis of breast tumor.Materials and MethodsFifty-four cases with single breast tumor underwent preoperative ultrasound elasticity imaging and MRI. Accuracy of ultrasound elastography strain rate ratio (SRR) of the tumor and surrounding normal breast tissue was measured by quantitative ultrasound elastography, and its combination with MRI were analyzed. ResultsThere was signiifcant differences on SRR between the benign group and the malignant group (2.24±1.28vs 4.96±1.73, t=2.648,P<0.05). Optimal threshold of ultrasonic elastography SRR in differential diagnosis of breast benign from malignant tumor was 2.41 determined by ROC curve. The accuracy of SRR, MRI and the combination of both in differentiating benign from malignant breast tumor was 81.48% (44/54), 85.19% (46/54) and 96.30%(52/54), respectively. There was no statistic difference between SRR and MRI in diagnostic accuracy (χ2=0.267,P>0.05). Combined both had higher diagnosis accuracy when compared with SR and MRI separately (χ2=6.000 and 3.967,P<0.05).Conclusion Ultrasonic elastography strain ratio is accurate and objective in differentiating benign from malignant breast tumors. It is a valuable quantitative index in clinical practice. Moreover, SRR combined with MRI can reduce the misdiagnosis rate.

The feasibility and the clinical value of the enzyme-multiplied immunoassay technique （EMIT） monitoring of blood concentrations of cyclosporine A （CsA） in patients treated with CsA were investigated after kidney transplantation. The validation method was performed to the EMIT determination of CsA blood concentration, the CsA whole blood trough concentrations （Co） of patients in different time periods after renal transplantation were monitored, and combined with the clinical complications, the statistical results were analyzed and compared. EMIT was precise, accurate and stable, also with a high quality control. The mean postoperative blood concentration of CsA was as follows： 〈1 month, （281.4± 57.9）ng/mL; 2 - 3 months, （264.5 ± 41.2） ng/mL; 4 - 5 months, （236.4 ± 38.9） ng/mL; 6 - 12 months, （206.5± 32.6）ng/mL; 〉12 months, （185.6± 28.1）ng/mL. The toxic reaction rate of CsA blood concentration within the recommended therapeutic concentration was 14.1%, significantly lower than that of the none-recommended dose group （37.2%） （P〈0.05）; the transplantation rejection rate was 4.4%, significantly lower than that of the none- recommended dose group （22.5%） （P〈0.05）. Using EMIT to monitor the blood concentration of CsA as the routine laboratory method is feasible, and is able to reduce the CsA toxicity and rejection significantly, leading to achieving the desired therapeutic effect.

Objective To explore the relationship between adjustment of immunosuppressant and prognosis in renal transplantation recipients with pulmonary infection. Methods The clinical data of 98 patients with pulmonary infection following renal transplantation were retrospectively analyzed.Patients were divided into two groups: conventional group (n = 45) and immunosuppressant adjustment group (n = 53). The mortality, recovery time and rejection rate in two groups were analyzed under the statement of serious infection (SOFA≥12) and slight infection (SOFA＜ 12) by sequential organ failure assessment (SOFA) score. Results When the SOFA scores ≥ 12, the mortality and recovery time in immunosuppressant adjustment group were significantly lower than in conventional group (P＜0.05), but there was no significant difference in the rejection rate between two groups (P＞0.05). When the SOFA scores ＜11, there was no significant difference in mortality and recovery time between the two groups (P＞0.05). The incidence of rejection in immunosuppressant adjustment group was significantly higher than in conventional group (P＜0.05).Conclusion Mortality could be decreased and course of anti-infection treatment could also be shortened by adjusting the immunosuppressant in renal transplantation recipients with serious pulmonary infection (SOFA≥12). Immunosuppressant agent was proposed to maintain the original treatment protocol when the infection was slight (SOFA＜12).
