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 study the clinical features of dengue cases infected with hepatotropic virus and Mycobacterium tuberculosis in Xishuangbanna, and to provide evidences to set up effective treatment programs for the dengue patients infected with the other diseases for hospitals.@*Methods@#The clinical characteristics of dengue cases infected hepatotropic virus and Mycobacterium tuberculosis were analyzed retrospectively on their symptoms and biochemical parameters from the People′s Hospital and the Infectious Disease Hospital of Xishuangbanna Prefecture in 2013 and 2015.@*Results@#The clinical characteristics of dengue cases infected with hepatotropic virus were typical, and inclued low incidence of urinary abnormalities, coagulation disorders and high-lactate dehydrogenase. Dengue cases infected with Mycobacterium tuberculosis had high incidence of shock, high-hematocrit, renal function and coagulation abnormalities, which suggested a trend of more serious illness than other groups obviously.@*Conclusions@#The rate of severe disease was higher in dengue cases infected with Mycobacterium tuberculosis than those infected with hepatotropic virus, which suggests that the dengue cases infected with Mycobacterium tuberculosis should be treated timely to reduce the severity of the diseases in the hospital.

ABSTRACT
@#Objective To observe the effect of interventional therapy of urokinase on sudden hearing loss.Methods65 patients with sudden hearing loss were divided into the treatment group (n=35) and control group (n=30). The patients of the treatment group were treated with urokinase pouring into vertebral artery accordingly into labyrinthine artery in order to improve internal ear microcirculation. Those of the control group were treated with routine drug dropping in vein. All patients of two groups were examined by pure tone test before and after treatment and the therapeutic effect of two groups was compared.ResultsIn the treatment group, the audition of 21 cases recovered, 12 cases got 15～30 dB increasing, 2 cases increased <15 dB. In the control group, the audition of 10 cases recovered, 4 cases got 15～30 dB increasing, 9 cases increased <15 dB and 7 cases had no obvious improvement. There was a significant difference between effects of two groups ( P<0.05).ConclusionThe effect of urokinase on sudden hearing loss is superior to routine drug dropping in vein.
ABSTRACT
@#ObjectiveTo explore the effect of sodium selenite on gentamicin-induced ototoxicity.MethodsTwenty guinea pigs were randomly divided into the experimental group and control group with 10 animals in each group. The animals were treated with i.m injection of gentamicin (200 mg/kg/d for 8 consecutive days, and at same time, the experimental group was added with p.o tablet of sodium selenite (1 mg/kg/d). Before and after the administration, hearing function was evaluated by examination for auditory brain stem responses (ABR). The cochlear outer haircells were observed by scanning electronic microscope (SEM) and transmission electronic microscope (TEM).ResultsABR threshold of the control group was about 30 dB above that of the experimental group (P<0.01). The latency of waveⅠof the control group was about 0.23 ms above that of the experimental group (P<0.01). Under SEM, the cilia of the majority outer hair cells of the control group lodged even disappeared, while that of the experimental remained regular. Under TEM, in outer hair cells of the control group, mitochondrial crests were obscure, out-membrane was damaged and local protruding, the number of secondary lysosomes was increased, myeloid bodies appeared, but in the experimental group, outer hair cells basically remained normal.ConclusionSodium selenite has antitoxic effect on guinea pig cochlea injury induced by gentamicin in vivo.
