Objective Zika virus disease is an acute infectious disease caused by Zika virus transmitted through Aedes mosquitoes. To explore the therapeutic effect of integrated traditional Chinese and Western Medicine for Zika virus disease, the treatment process of the first imported case in China was reviewed. Methods The first imported Zika virus disease in China was admitted to Ganxian People's Hospital in Jiangxi Province on February 6th, 2016, and the patient received isolation treatment for 9 days and cured later. The effect of antiviral treatments including Xiyanping injection was evaluated based on clinical diagnosis and treatment process of the patient. Results A 34-year old male patient was admitted with chief complaint of fever for 9 days, orbital pain and itching rash for 4 days on February 6th, 2016. ① Epidemiological characteristics: the patient was bitted by mosquitoes during his business trip in Venezuela since January 1st, where Zika virus disease was spreading. On January 20th he had dizziness without fever, and the symptom disappeared after taking medicines without details. Paroxysmal dizziness, chills and mild fever without myalgia was experienced on January 28th. On February 3rd small red rash appeared in the neck, spreading to anterior part of chest, limbs and trunk, and the fever, fatigue, nausea was continued, and a new symptom of paroxysmal pain in back of ears and orbits appeared, during which he had not go to hospital. The symptoms relieved on February 4th. He returned to Ganxian County on February 5th, he had yellow stool 3 times with normal temperature, without abdominal pain, and red rash still appeared in the neck. He went to Ganxian People's Hospital on February 6th, 2016. ② Clinical manifestation: the vital signs showed a temperature of 36.8 ℃, a pulse rate of 80 bpm, a respiratory rate of 20 bpm, and a blood pressure of 110/70 mmHg (1 mmHg = 0.133 kPa). It was showed by physical examination that red rash appeared in the neck, and no superficial enlarged lymph nodes were found. Bilateral conjunctival congestion was obvious, physiological reflex existed and pathological reflex was not found. ③ Auxiliary lab test and examination: no abnormal finding were revealed throughout examination and laboratory tests, including routine blood test, liver function, renal function, serum myocardial enzyme, electrolyte, blood sugar, C-reactive protein (CRP), troponin I (TnI), and procalcitonin (PCT), except slight prolongation in activated partial thromboplastin time (APTT, 38.6 s) on February 6th; and slightly dense shadow in left lung in lung CT scan, considering inflammatory changes and slight emphysema (especially in the left lower lung) as well as bilateral renal calculus on February 8th. No significant abnormalities were found in electrocardiogram and B ultrasound test of liver, spleen, and pancreas. ④ Virus confirmation: Zika virus nucleic acid was positive reported by Jiangxi Province Center for Disease Control and Prevention (CDC) on February 7th and Chinese CDC on February 9th, respectively, though Dengue virus were negative reported by Ganzhou CDC on February 6th. Right after the first diagnosis, anyone who had been in close contact with the patient received medical monitoring. ⑤Treatment process: on February 6th, symptomatic treatment was prescribed since admitted into the infectious isolation wards and daily intravenous drip of Xiyanping injection 250 mg was prescribed for antiviral therapy. On February 7th, the patient had no fever, with occasional chills, neck rash was disappeared, orbital pain relieved and bilateral conjunctival hyperemia range was paler and narrowed, and his condition improved. Ibuprofen was administered for defervesce 3 times a day when his temperature reached to 37.5 ℃ at 16:00. On February 8th, the patient had no fever, times of chills was significantly reduced, without myalgia and rash, orbital pain and conjunctival hyperemia further recovered. On February 9th, bilateral eyes slightly tingling, mild conjunctival congestion, no fever chills or other discomfort was found. The chloramphenicol eye drops was prescribed for relieving sting pain with conjunctival congestion twice a day as recombinant human interferon alpha eye drops was out of store. The patient was comfortable from February 11th to February 13th. Blood and urine test for Zika were reported negative by the Chinese CDC and Jiangxi Province CDC. Because all the discharge criteria were satisfied, the patient was discharged on February 14th. Conclusions At present, there is no specific effective drug to prevent and treat Zika virus disease effectually. After receiving symptomatic treatment and antiviral treatments including Xiyanping injection, the patient's symptoms were relieved. Zika virus nucleic acid in blood and urine was negative. The patient was discharged. Combination of traditional Chinese medicine and Western medicine maybe a good method to prevent and treat Zika virus disease.

Objective To evaluate the efficacy of pleth variability index (PVI) in guiding volume therapy in the patients undergoing thoracoscopic surgery.Methods Forty patients of both sexes, aged 18-64 yr, with body mass index＜35 kg/m2 , of American Society of Anesthesiologists physical status I or Ⅱ ,scheduled for elective thoracoscopic lobectomy, were randomized into 2 groups (n =20 each) : control group (group C) and PVI group.During induction of anesthesia, multiple electrolyte solution was infused rapidly as a bolus of 250 ml, followed by a 2-8 ml · kg-1 · h-1 infusion.In group C, 6％ hydroxyethyl starch 130/0.4 and sodium chloride injection 50 ml and metaraminol 0.5 mg were administered to maintain mean arterial pressure ≥ 65 mmHg.In group PVI, 6％ hydroxyethyl starch 130/0.4 and sodium chloride injection 50 ml and metaraminol 0.5 mg were administered to maintain PVI ≤ 13％ and mean arterial pressure ≥ 65 mmHg.Immediately after the beginning of one-lung ventilation (T1) , immediately after the termination of one-lung ventilation (T2) and at 1 h after surgery (T3) , arterial oxygen saturation were recorded, and arterial blood samples were collected for blood gas analysis, and for determination of lactic acid concentrations.The blood creatinine concentrations were measured at 24 h before and after surgery.The fulid balance was recorded.Results The amount of colloid solution infused, total volume of fluid infused and lactic acid concentrations at T3were significantly lower in group C than in group PVI.There were no significant differences in the amount of crystralloid solution infused, urine volume, blood loss, arterial oxygen saturation at each time point, and blood creatinine concentrations at 24 h before and after surgery between the two groups.Conclusion PVI-guided volume therapy can not only maintain adequate blood volume and tissue perfusion, but also reduce the amount of fluid infused, and is helpful in mitigating lung water overload when used for the patients undergoing thoracoscopic surgery.

Objective To investigate the rat bone structural changes of lower limb following lumbar nerve dorsal roots section.Methods Forty-eight mature female Wistar rats were divided into posterior radi- cotomy(PR)and comtrol groups randomly.The bilateral femoral bone mineral density(BMD)and biome- chanics characteristics were analyzed 2,4 and 8 weeks after the radicotomy.The same operation except the radicotomy was done in the sham group.Results In PR group,2,4,and 8 weeks after the radicotomy,the BMD of femur was(0.221?0.008)g/cm~3,(0.213?0.015)g/cm~3 ,and(0.216?0.105)g/cm~3 ,respective- ly;while that was(0.223?0.005)g/cm~3,(0.218?0.014)g/cm~3 ,and(0.208?0.111)g/cm~3 in control group.No significant difference was observed between the two groups(P＞0.05).In PR group,2,4,and 8 weeks after the operation,the mean maximum load in three-point bending test of femun midshaft was(93.64?8.76)N,(89.77?11.18)N and(93.21?8.74)N,respectively,and was lower than the values of the con- trol group at the same time point(95.94?6.29)N,(91.63?9.43)N,(95.57?8.64)N,However,there was no significant difference between the two groups(P＞0.05).Accordingly,there was no significant difference in the energy absorption in femun midshaft between the two groups(P＞0.05).Conclusion The selective rhizotomies of part lumbar never dorsal roots might not cause the loss of the femur BMD and the change of bio- mechanics property significantly in short period.

Objective To determine the correlation between mouse maerophage metalloelastase (MME)and vascular endothelial growth factor(VEGF)expression involved in angiogenesis of colon cancer.Methods A eDNA fragment coding for domainsⅠandⅡof MME was transfected into murine CT-26 colon cancer cells that were MME deficient.The enzymatic activity of recombinant MME was confirmed by cleavage of native substrate in vitro.An orthotopic implantation model was established by using MME-transfected cells and control cells.Tumor samples were subjected to in situ hybridization (ISH)and immunohistochemical staining(IHC)to detect expressions of MME and VEGF.The microvessel counting was used to assess angiogenesis of murine colon tumors.Results It was demon- strated that the tumor growth was significantly inhibited in MME-transfected group compared with pcDNA3.1 transfected and nontransfected groups(P＜0.001).It was also found that,compared with pcDNA3.1-transfected and nontransfected groups,the microvessel formation in MME transfected group was significantly reduced(P＜0.001).The expression of VEGF mRNA and protein was significantly lower in MME-transfected group than those in the controls,as demonstrated by ISH(MME-transfected group versus pcDNAa.1-transfected group,P=0.028;and versus nontransfected group,P=0.003) and by IHC(MME-transfected group versus pcDNA3.1-transfected group,P=0.025;and versus non- transfected group,P=0.008).Conclusions The MME gene transfected into murine colon cancer cells can effectively suppress the growth of orthotopic tumors by inhibition of vaseularity.Both MME and VEGF gene expression is highly associated with the vascularity of tumors,which may depend on a hal- ance between MME and VEGF expression.

In this paper, the five strains of Polygonatum odoratum were used as the experimental materials to test the supercooling point, freezing point, the degree of supercooling, the transition stage time, cooling time and water composition of the plant tissue. The cold resistance of P. odoratum was analyzed with the Gray Correlation Method. The results showed that the cold resistances of the five strains of P. odoratum were different, and the water content of plant tissue had some relevance with freezing point and supercooling point, whereas, it could not be measured when the moisture content was too low. The order of cold resistance of the five strains of P. odoratum was ZJCY, DYYZ, XYYZ, CYYZ and JZ I.

BACKGROUND:Percutaneous vertebroplasty and kyphoplasty are both effective in the treatment of osteoporotic vertebral compression fractures, but different in the distribution and dispersion of bone cement. ＜br> OBJECTIVE:To analyze the factors affecting the bone cement dispersion within the vertebral body in treatment of osteoporotic vertebral compression fracture with vertebroplasty or kyphoplasty. ＜br> METHODS:A total of 41 patients with osteoporotic vertebral compression fractures were included, and divided into three groups:group A (22 cases receiving high viscosity bone cement vertebroplasty treatment), group B (5 cases receiving high viscosity bone cement kyphoplasty), group C (14 cases receiving low viscosity bone cement vertebroplasty treatment). The groups A and C were divided into subgroups according to bone cement injection volume, time from fracture to operation, preoperative degree of vertebral compression. The distribution and dispersion of bone cement in the vertebra were reconstructed by the CT three-dimensional imaging and volume rendering analysis. ＜br> RESULTS AND CONCLUSION:In the three groups, after operation, relative dispersion area and relative dispersion volume in the vertebrae had no obvious difference, and the bone cement could al diffuse to upper and lower lamina cross the vertebral midline. There was no significant difference in bone cement diffusion coefficient among the three groups. In a certain range, the bone cement injection volume and bone cement dispersion volume was positively correlated. In groups A and C, bone cement diffusion coefficient decreased with the increasing of bone cement injection volume, time from fracture to operation, and the compression degree of the fractured vertebrae, but showed no significant correlation with bone cement viscosity.
