ABSTRACT
Objective@#To observe the disease type and the changes of symptom load during treatment of patients with Ph chromosome/BCR-ABL fusion gene negative myeloproliferative neoplasm (MPN).@*Methods@#A total of 84 patients with MPN diagnosed from May 2017 to January 2019 in People′s Hospital of Longhua District of Shenzhen were selected, and were divided into polycythemia vera (PV) group, essential thrombocyhemia (ET) group, and myelofibrosis (PMF) group according to their subtypes, with 28 cases in each group. The scores of MPN-SAF-TSS were compared among the three groups. Besides, the scores of the scale (myeloproliferative neoplasm symptom assessment form total symptom score, MPN-SAF-TSS) in different treatment periods (at the time of the visit, when the disease progressed, when the disease was stable, when the clinical improvement was made, when the partial remission was completed, at the time of remission and recurrence) were also compared.@*Results@#At the time of initial diagnosis, there were significant differences in the incidences of symptom burdens among the three groups of MPN patients with abdominal fullness (χ2=6.095, P=0.047), abdominal discomfort (χ2=7.342, P=0.025), poor mobility (χ2=13.029, P=0.001), inattention (χ2=6.099, P=0.047), pruritus (χ2=6.956, P=0.031), bone pain (χ2=7.807, P=0.020), fever (χ2=8.000, P=0.018) and weight loss (χ2=27.340, P<0.001). The incidences of poor mobility (85.71%, 24/28), inattention (67.86%, 19/28) and weight loss (82.14%, 23/28) in PMF group were significantly higher than those in PV group [42.86% (12/28), 39.29% (11/28), 35.71% (10/28)] and ET group [46.43% (13/28), 39.29% (11/28), 14.29% (4/28)] (all P<0.05). The incidences of abdominal discomfort (75.00%, 21/28) and bone pain (60.71%, 17/28) in PMF group were higher than those in PV group [39.29% (11/28), 25.00% (7/28)] (both P<0.05). The incidences of abdominal fullness (89.29%, 25/28) and fever (42.86%, 12/28) in PMF group were higher than those in ET group [60.71% (17/28), 10.71% (3/28)] (both P<0.05). The incidence of pruritus in PV group (71.43%, 20/28) was higher than that in ET group (42.86%, 12/28) and PMF group (39.29%, 11/28) (both P<0.05). Symptom load scores of patients with fatigue (χ2=368.594, P<0.001), abdominal fullness (χ2=261.312, P<0.001), abdominal discomfort (χ2=195.629, P<0.001), poor mobility (χ2=217.862, P<0.001), lack of concentration (χ2=280.664, P<0.001), night sweats (χ2=239.650, P<0.001), pruritus (χ2=254.418, P<0.001), bone pain (χ2=180.291, P<0.001), fever (χ2=231.613, P<0.001) and weight loss (χ2=227.831, P<0.001) were significantly different during different therapeutic periods. The fatigue symptom load score was higher when the disease progressed than that at the time of the visit (P<0.05), and the symptom score of abdominal fullness was lower than that at the time of visit (P<0.05). Symptom load scores of weakness and pruritus when the condition was stable was lower than those when the disease progressed (both P<0.05). When the clinical improvement was made, symptom load scores of weakness, abdominal discomfort, inattention, night sweats, weight loss were lower than those when the disease was stable (all P<0.05). Symptom load scores of abdominal fullness, poor mobility, inattention, night sweats and pruritus in partial remission period decreased compared to temporary improvement period (all P<0.05). Compared to the partial remission period, the symptom load scores of weakness, abdominal fullness, night sweats, pruritus, bone pain and weight loss in complete remission period were lower (all P<0.05). At last, symptom load scores of weakness, abdominal fullness, abdominal discomfort, poor mobility, inattention, night sweats, pruritus, bone pain, fever and weight loss in recurrence period were higher than those in complete remission period (all P<0.05).@*Conclusion@#There are several differences in the main clinical symptoms among patients with different MPN subtypes, and there are significant changes in the main clinical symptoms as the disease progresses or turns around.

ABSTRACT
Objective To evaluate the efficacy of thoracic cavity perfusion with cisplatin combined with mannan peptide in nasopharyngeal carcinoma patients with malignant pleural effusion.Methods 47 cases of nasopharyngeal carcinoma patients with malignant pleural effusion with a median age of 50 years old (41-70 years old) were enrolled.Pleural effusion occurred at 38.5 months on average after diagnosis,unilateral effusion was seen in 45 patients (95.7 ％),bilateral effusion was seen in 2 patients (4.2 ％).Cisplatin combined with mannan peptide was administered through pleural puncture by PICC center vein pipe after drainage.Data of survival complications and response to the treatment were reviewed.Results 17 patients (36.1％) had a complete remission (CR),21 patients (44.6 ％) had partial remission (PR),and the total remission rate (CR+ PR) was 80.9 ％.The median survival time was 10.5 months.Patients with pleural fluid pH ≥ 7.2,glucose ≥ 60 mg/L,and lactic dehydrogenase (LDH) ＜ 600 U/L showed association with good efficacy,the efficacy rates were 85.0 ％ (34/40),86.5 ％ (32/37),89.5 ％ (34/38),the median survival time were 11.5,12.0,12.5 months.Pleural fluid pH ＜ 7.2,glucose ＜ 60 mg/L,and LDH ≥ 600 U/L showed association with poor efficacy,the efficacy rates were 42.8 ％ (3/7),50.0 ％ (5/10),44.4 ％ (4/9),the median survival time were 6.5,6.5,6.0 months (P ＜ 0.05).The curative effect of the patients with bone metastasis and (or) pulmonary metastasis without liver metastasis was more similar with that of the patients with liver metastases [(47.0 ％ (16/34) vs 57.1％ (4/7),x2 =0.01,P =0.29].But median survival time had significant difference (11.0 vs 6.0 months,P =0.02).The Cox multi-factor analysis confirmed that the LDH value of effusion was an independent factor as prognosis evaluation.Major side effects of the treatment included fever,chest pain,nausea and vomiting.Conclusion Thoracic cavity perfusion using cisplatin combined with mannan peptide is effective in the treatment of malignant pleural effusion in nasopharyngeal carcinoma patients with pleural effusion,with relatively low toxicity.LDH value is a predictive factor for survival.The patients with liver metastases appeare poor median survival time.
ABSTRACT
[Objective]To discuss the postoperative effect of the posteromedial structure injury (medial collateral ligament,MCL,posterior oblique ligament,POL) of the knee.[Method]Fourteen cases of complex posteromedial structure injury were treated from January 2002 to October 2007,twelve of which combined with ACL injury and two combined with PCL injury.Classification of posteromedial structure injury:typeⅠ,8 cases,ruptured from the femur with small bone fragment;type Ⅱ,2 cases,ruptured from the femur without bone fragment;typeⅢ,2 cases,the structure were torn from the body area,and type Ⅳ,2 cases,ruptured from the tibia.The injury were repaired by different techniques according to the classification.Eight cases applied star-shaped steel plate,four with GⅡ anchor screws(2 attached to the femur and 2 to the tibia adhesion respectively),and 2 cases with end-to-end suture.The ruptured ACL and PCL were reconstructed by arthroscopy.Autologous semitendinosus and gracilis were used for 8 ACL reconstruction and B-T-B technique for the other two ACL reconstruction.Two ruptured PCL were reconstructed with allograft of Achilles tendon.[Result]All cases were followed up for twelve months at average(6-18 months) except two cases only for four months.The functional score of the knees were improved from 56.7(50-60) preoperatively to 81.2(74-94) postoperatively in average valued by Lysholm system.Ten cases received normal knee flexion and extension range after repair of the posteromedial structure while 2 cases with restricted 5 degree extension.Nine cases received excellent result in lateral stress test while 2 cases with "+" and 1 case with "++" at zero angle.[Conclusion]Early repaire for the posteromedial structure injury will deliver excellent knee stability.
ABSTRACT
<p><b>OBJECTIVE</b>To study DNA damage of three kinds of gasoline oxygenates.</p><p><b>METHOD</b>Single cell gel electrophoresis assay(Comet assay) was used to detect the damage effects of three gasoline oxygenates[methyl tertiary butyl ether(MTBE), ethanol anhydrous(EA) and dimethyl carbonate(DMC)] on DNA in L-929 mice fibroblasts.</p><p><b>RESULTS</b>In certain concentation(37.500-150.000 mg/ml), MTBE could directly cause DNA damage of L-929 mice fibroblasts. There was obvious dose-effect relationship, i.e. when the concentration of MTBE was increased from 9.375 to 150.000 mg/ml, the comet rate also increased from 4% to 85%, and the length of comet tail changed correspondingly. The results of EA and DMC were negative.</p><p><b>CONCLUSION</b>Under the condition of this experiment(150.000 mg/ml), MTBE could directly cause DNA damage while the effect of EA and DMC on DNA damage was not found.</p>
