800 ng/L) and elevated NO content were enrolled to study the efficacy of treatment with a combination of drugs for heat- reducing, purgation, resolving and tonification for 6 months to 2 years. The symptoms and signs were markedly ameliorated: the level of GPT, GOT, globulin, albumin and bilirubin contents restored to normal level. In B -ultrasonographic examination, a decrease the width of the portal vein and the spleen was found in 50% of the patients. The authors concluded that the combined use of drugs for heat- reducing, purgation, resolving and tonification was effective in treating hyperhyaluronemia due to liver cirrhosis. The ingredient rhemannia root may play the key role in its actions of expelling toxic materials, normalizing the functions of the viscera and discharge of bile, and removing the stagnated heat.

砄bjective: To study the cause,clinical characteristics and treatment of zygomatic complex fractres(ZCF). Methods: Medical records of 79 cases with ZCF and followed up for 3 months to 2 years were reviwed and analysed. Reduction and cosmatic outcome were assessed by clinical evaluation and postoperative images. Results: Of the 79 patients, 87.3% were male, with the peak incidence in the age group from 20 to 40 years old(73.5%). 58.2% were due to traffic accidents, 15.2% to assalts. Incidence of malar asymmetry, enophthalmos, diplopia,limited mandiblar movement and malocclusion were 83.5%,24.1%,19.0%, 60.8% and 35.4% respectively. Of the nerve disturbances, 41.8% of the infraorbital and 13.9% of the facial nerve were involved. For the treatment the most freqently used approach was the coronal incision in combination with the maxillary vestibular incision(30.4%), followed by coronal incision alone(22.8%). 40.5% of the patients were treated by rigid internal fixation with titanium miniplates alone or combined with wire fixition(20.3%). All patients but five regained satisfactary facial appearance. Three patients still showed slightly post surgical enophthalmos and diplopia at a 6 month follow up. All of the patients with malocclusion regained their functional occlusion after treatment. Conclsions:A variety of techniques can be used in the treatment of ZCF. Among them the coronal incision in combination with other incisions or alone and rigid internal fixation can produce a satisfactary outcome.

Methonds: 39 cases with the final pathological diagnosis of lymphonode reactive hyperplasia were retrospectively reviewed.Results: 39 patients had th e incidence at the age of 7～61 years old and the medical history of 14 days ～8 years.The patients consulted doctors because of unilateral or bilateral painles s masses in the superior neck and low fever.32 of them underwent repeated antib iotics treatment.On admission 9 cases were diagnosed with lymphoma,6 tuberculos is,6 inflammation of lymph node and 18 were without identified diagnosis.The f inal pathological diagnoses of all the 39 cases was LRH.Antibiotic treatment wa s effective in the patients.Conclusion:LRH was usually mis diagnosed as other diseases.Swelling of lymph nodes in superior neck with low fe ver is the main symptom of LRH.

Objective To inspect the correlation of synthetic effect criteria to sensitivity,reliability of late stage lung cancer curative effect verdict and median survival time. Method Using size change of tumor,symptom change related to tumor,Karnofsky score,body weight etc.as synthetic effect criteria and nstituting clinical synthetic effect criteria,to assess the curative effect of late stage lung cancer patients who received different treatment in department of tumor of Xiyuan Hospital between March 1997 and March 2000, to analysis medium survival time, and being compared with RR of tumor.Result 52 patients entered this experiment, in which 42 patients were assessable (follow up), 13 patients were effective(30.95％ ),17 were patients stable(40.48％ ),12 patients deteriorated (28.57％ ).The result of tumor objective remission rate: CR is 0,PR is 16.67％ (7 patients),NC is 64.29％ (27 patients) and PD is 19.05％ (8 patients).There was apparent difference between two effect criteria(P< 0.05).The mean survival time of this group is (9.3± 1.6)months,median survival time is 10.5 months(2～ 8months),survival rate of one year is 33.33％ (14 patients).In the patients who live longer than median survival time, most of them survive associated with tumor existence who are in NC of tumor objective remission rate, but also in the effective column of synthetic effect criteria. Compared with tumor objective remission rate,the synthetic effect criteria have more apparent correlation to survival time. Conclusion In the assessment of late stage lung cancer,synthetic effect criteria has better sensitivity and reliability,and emphasize survival quality,at same time it reflect the reaction of tumor and host to treatment,it reflect prognosis of tumor preferably and have better correlation to the survival time. It can be used as clinical effect criteria of late stage lung cancer after further consummation.

Objective:To explore the mechanism of the embolism and sclerotherapy of fibrin glue combined with bleomycin (FG/BLM) for the treatment of cervicofacial vascular malformations by color doppler ultrasound.Methods:10 patients with venous malformation(VM) and 10 patients with arterio-venous malformation(AVM) were included.All patients underwent embolism and sclerotherapy of FG/BLM guided by ultrasound.Color doppler ultrasound was used to record the real-time two-dimensional ultrasonography and color doppler image.The flow and distribution of FG/BLM after injection into the lesions were observed.Results:Two-dimensional ultrasonography showed clumps or flake strong echo after immediate injection of FG/BLM into the cavity of VMs,then floated in the abnormal venous lumen and diffused throughout the cavity.At the later stage the lesions were filled by a large number of flocculent and netted low echo,and patchy strong echo.The volume of VMs cavity expanded dramaticlly,and the blood flow signal was significantly decreased.After injection of FG/BLM into the lumen of AVMs,clumps or flake strong echo were observed,then most of the snowflake strong echo rapidly filled or scattered along with blood stream to the distal part of the vessels.The color doppler showed significantly decrease of blood flow signal.Conclusion:FG/BLM injection can embolize and block the draining vein of VM,and play a role on the storage of sclerozing agent.FG/BLM injection can embolize both the dilated blood vessels and capillary network of AVM.

Objective To monitor the levels of NO and IL-18 in neonatal hypoxic-ischemic encephalopathy (HIE), to explore the relation of NO, IL-18 and HIE. Methods HIE infants admitted in our hospital from January to Novermber of 2007 were taken as observation group and normal neonates were chosen as control group. In each group,the concentrations of NO and IL-18 were tested on 1 day,3 days,7 days and 14 days. Results On the first day after birth,the levels of serum NO and IL-18 in control group were (6.40±4.24) μmol/L and (2.84± 2.53)ng/L,in mild HIE group were (21.55±7.23) μmoL/L and (6.79±1.96) ng/L,in moderate HIE group were (33.38±2.81) μmol/L and (14.07±2.91) ng/L,in severe HIE group were (66.39±18.03) μmoL/L and (26.85±9.82) ng/L. The levels of serum NO and IL-18, in HIE groups were higher than those in control group (P<0.01), were much higher in patients with moderate and severe HIE than those with mild HIE (P<0.01). On 14 days,the levels of serum No and IL-18 were not different in moderate HIE groups and those in the control group (P>0.05), butwere higher in the severe HIE groups than those in the control group [NO and IL-8 level: (5.38± 4.79) μmol/L and (2.39±1.41) ng/L in control group and (24.89±9.43) μmol./L and (13.43±3.23) ng/L in severe HIE group(P<0.01)]. Conclusion NO and IL-18 are involved in the whole course of HIE, which are correlated with the severity of condition. They may be acted as indicators in monitoring pationts' conditon.

Objective To investigate the effects of breviscapine injection on intestinal injury induced by intestine ischemia-reperfusion(IIR). Methods 48 males SD rats with 8-week old were randomly divided into 4 groups:Sham,intestine ischemia-reperfusion(IIR),EB+IIR,TP+IIR. Breviscapine injection 20 mg/(kg·d) was given intraperitoneally in EB + IIR group. TPCA-1(12 mg/kg)was given intravenously 30 min before surgery in TP+IIR group. Rats were subjected to superior mesenteric artery occlusion consisting of 45 min of ischemia and 6 h of reperfusion;sham laparotomy served as controls. Intestine pathology was assayed by H&E staining. Con-centrations of TNF-α,IL-1β,and IL-6 in intestinal mucosa were determined by ELISA. The protein expressions of IκB-α,NF-κB ,ICAM-1of intestine tissue were assayed by western blot. Results IIR induced serious intesti-nal injury ,evidenced as poor intestine pathology ,elevation of TNF-α,IL-1β,and IL-6 levels in intestinal mu- cosa,accompanied with IκB-α/NF-κB/ICAM-1 pathway activation. However,breviscapine injection pretreatment could inhibit IκB-α/NF-κB/ICAM-1 pathway activation,leading to reduction of TNF-α,IL-1β,and IL-6 concen-trations in lung,finally attenuate ALI induced by IIR. Conclusion Breviscapine injection pretreatment could atten-uate inflammation in intestine after IIR injury via inhibiting IκB-α/NF-κB/ICAM-1signaling pathway.

Abstract: Objective To compare the screening effects of RDT, microscopy and PCR for malaria among residents in low malaria areas and elimination areas, and to investigate the presence of malaria in residents of border Villages in Cangyuan Va County and asymptomatic infections in surrounding areas, providing a basis for preventing re-introduction of malaria after elimination. Methods From August 2020 to March 2021, the fingertip blood of the investigated subjects was collected from three survey sites in the border area between China and Myanmar, namely Banlao Township in Cangyuan Va Autonomous County of Lincang City, Banwai District, Mengmao County, the Second Special Zone of Shan State, Myanmar, Yongmo and Dayan Township, Nandeng Special Zone, the Second Special Zone of Shan State, Myanmar. The malaria parasite antigen detection test kit, malaria parasite microscopic examination, fluorescent quantitative PCR and nested PCR were used to detect the asymptomatic infection of malaria parasites. Results A total of 1 040 blood samples were collected, including 606 from China and 434 from Myanmar, with 506 males and 534 females. Among them, , there were 51 individuals aged 0 to <5 years, 283 aged 5 to < years, 187 aged 15 to < years, 232 aged 30 to <45 years, 205 aged 45 to < years, and 82 aged ≥60 years. All 1 040 people tested negative for plasmodium antigen detection kit. One case of Plasmodium vivax detected by plasmodium microscopic etiology, with a detection rate of 0.10%. One case of P. vivax was also detected by fluorescent quantitative PCR and nested PCR, with a detection rate of 0.10%. Among them, one case of P. vivax was detected in Banwai District, Mengmao County, the Second Special Zone of Shan State, Myanmar, with a detection rate of 0.35%. The detection rates of malaria parasites in Banlao Township in Cangyuan Va Autonomous County of Lincang City, Yunnan Province and Yongmo Township and Dayan Township, Nandeng Special District, the Second Special Zone of Shan State, Myanmar were both 0. The difference in the detection rate of malaria parasites among the three survey sites was not statistically significant (χ2 =2.682, P>0.05). The asymptomatic P. vivax infection was detected in a 6-year-old girl from Banwai District, Mengmao County, the Second Special Zone of Shan State, Myanmar. Conclusions RDT is not suitable for malaria screening in low malaria area and elimination area. Microscopic examination and PCR can be used for malaria screening, but PCR operation is complex and costly. In surrounding areas outside of China, malaria is still prevalent, while there is no source of malaria infection in border villages of Cangyuan Va County. However, there is a risk of importation, and timely and effective measures should be taken to prevent reintroduction and transmission.
