ABSTRACT

OBJECTIVES@#To establish a diatom database by analyzing the quatity, species distribution and differences of diatom in water samples of the whole navigable sections of the Beijing-Hangzhou Grand Canal, to provide a reference for the inference of the drowning site.@*METHODS@#Water samples were collected at 22 sites in the navigable sections of the Beijing-Hangzhou Grand Canal (Jining section to Yangzhou Section), and the diatoms at each site were qualitatively and quantitatively analyzed by using graphite digestion-scanning electron microscopy.@*RESULTS@#Sampling site T (Laohuaijiang River Line, Gaoyou City, Yangzhou City, Jiangsu Province) had the highest number of diatoms, while sampling site O (Siyang County, Suqian City, Jiangsu Province) had the lowest number of diatoms, with a large gap of 68 times. At sampling site Q (Jiangpu District, Huaian city, Jiangsu Province), there were 19 species of diatoms. The sampling site O had the least diatoms, with 7 species. There were no significant differences in species evenness and species diversity at each sampling site (P>0.05). Some sampling sites have characterized diatoms, such as Caloneis at station A (Taibai Lake, Weishan County, Shandong Province), Rhoicosphenia at station B (Nanyang Town, Weishan County, Shandong Province), Amphora at station I (Taierzhuang District, Zaozhuang City, Shandong Province) and Epithemia at station J (Pizhou 310 national highway, Xuzhou City, Jiangsu Province).@*CONCLUSIONS@#The species richness of diatoms gradually increased from north to south. Diatom species richness and species diversity might be higher in areas with complex environments and large population flow. Climate type has a certain influence on the distribution of diatoms.

ABSTRACT

To investigate the space-time patterns of schistosomiasis after the stage of transmission controlled in Hubei Province, so as to provide the reference for precise controlling.The data of human schistosomiasis cases in Hubei Province from 2015 to 2016 and basic information of human schistosomiasis cases and serum antibody titer of human schistosomiasis cases in 2016 were collected and analyzed. The spatial clustering of human schistosomiasis was detected by the Flexible spatial scan statistics and Kulldorff circular scan statistic, respectively.Totally 64 819 serological positive cases from 51 counties and 1 504 stool hatching positive cases from 17 endemic counties were reported in Hubei Province in 2015, and 39 365 serological positive cases were reported from 48 counties in 2016. All of them were identified as the research objects. No stool hatching positive cases were reported from the routine work in the whole province in 2016. There were 1 603 cases of the highest antibody titer (1∶80 or more), with the proportion of 4.07%. According to the results of Kulldorff spatial clustering analysis, there were eight and six spatial clustering areas in the distribution of serological positive cases and stool hatching positive cases in 2015, respectively. The numbers of spatial clustering areas in the distribution of serological positive cases and the cases of the highest antibody titer (1∶80 or more) were eight and five in 2016, respectively. According to the results of Flexible spatial clustering analysis, there were three and two spatial clustering areas in the distribution of serological positive cases and stool hatching positive cases in 2015, respectively. The numbers of spatial clustering areas in the distribution of serological positive cases and the cases of highest antibody titer (1∶80 or more) were two and one in 2016, respectively.The distribution of human schistosomiasis cases is not balanced, and there is spatial clustering in Hubei Province. So the key area for prevention and control is on the middle and lower reaches of the Yangtze River in the future.

ABSTRACT

The sources of clinical efficacy of slow needle insertion is discussed. From the basic factors of slow needle insertion, the requirements of this manipulation, main points of 4 steps (to straight the needle, to press softly, to twirl the needle and to hold without brute force), keys of operation and its significance are analyzed. Slow needle insertion is not only beneficial to the management and regulation of Shen (spirit) and induction of qi in the process of the spirit unity of doctor and patient, but also accumulates the needling sensation among three levels of the superficial, middled and deep layers of an acupoint, which could promote the curative effect.

ABSTRACT

<p><b>OBJECTIVE</b>To analyze the short-term and long-term effect of Er-yttrium aluminum garnet (Er-YAG) laser in stapes surgery.</p><p><b>METHODS</b>There were 86 patients operated by the Er-YAG laser stapedotomy from 2001 to 2007 were analyzed retrospectively, with 23 male, 63 female and 13 double ears and with the average age of 48 years old, ranging from 12 to 78. All of 99 ears suffered deafness of conduction. The average air-bone-gap (ABG) of all patients before surgery was (37.4+/-9.0) dB HL (ranging from 13.7 to 58.7 dB). The patients followed-up over 6 weeks after the surgery was regarded as the short-term result, while over one year follow-up as the long-term effect (according to the standard of the Committee on Hearing and Equilibrium of the American Academy of Otolaryngology-Head and Neck Surgery). The followed-up average time was (26.3+/-15.8) months (range from 14 to 73 months). The pre-post-operation average bone conduction auditory threshold of 2 kHz and 4 kHz were observed. The data of the patient whether or not has the symptoms of tinnitus and dizzy and the lasted days were also recorded.</p><p><b>RESULTS</b>After surgery, short-term ABG of 99 ears was (15.7+/-8.7) dB, matched-pairs t test with the numbers of before surgery, t=22.79, P<0.01. The results of 45 ears (45.5%) with ABG<10 dB or air conduction improved more than 30 dB were regarded as excellence. The air conduction of 88 ears (88.9%) improved more than 15 dB was regarded as utility. With 82 ears (82.8%) followed-up more than 1 year, the average ABG was (11.7+/-6.8) dB, matched-pairs t test with the numbers of before surgery, t=23.37, P<0.01, compared with the short-term visit result [(15.3+/-9.2) dB, 82 ears], t=4.82, P<0.01, both of which were considered statistically extremely significant. Among them, 50 ears (61.0%) have the excellent effect while 74 ears with (90.2%) ABG<20 dB. The average bone conduction auditory threshold in 2 kHz was (34.5+/-15.0) dB before surgery, matched-pairs t test with short-term visit result (33.4+/-15.9) dB, t=1.96, P=0.026 14, with long-term visit result (32.7+/-15.2) dB, t=3.24, P=0.000 87, all of which had the significant difference, manifest that the Cohort's notch had been improved after the surgery. The data of bone conduction auditory threshold of 4 kHz with long-term following-up result matched-pairs t test with that of surgery before, t=0.76 (P>0.05), which showed the change of the bone conduction had no statistics difference. There were 55 ears had the persistent tinnitus before surgery, in which 42 ears (76.4%) with no the tinnitus, 13 ears with same to that of preoperative, and 3 ears (3.0%) with remaining tinnitus after surgery but who had not it preoperation and all disappeared after 2 - 3 days. There were 12 ears (12.1%) with light dizzy after surgery, but their live could deal with himself and the average dizzy lasted 2.3 days.</p><p><b>CONCLUSIONS</b>Er-YAG laser stapes surgery is safe to the inner ear, and it primal free from the imminent risk in stapes surgery, so the effect can be affirmed.</p>

ABSTRACT

<p><b>OBJECTIVE</b>To explore the efficacy and mechanism of Yixuesheng capsule (, YXS) combined with recombination human erythropoietin (RHE) in treating male neoplastic anemia (NA).</p><p><b>METHODS</b>Sixty-five patients were randomized into two groups, the 33 patients in the treated group treated with a combined therapy of YXS and RHE, and the 32 in the control group treated with RHE alone, all for 12 weeks. Related clinical indexes, including hemoglobin (Hgb), red blood cell (RBC), hematocrit (HMC), testosterone (T), estradiol (E(2)) and prolactin (PRL), were measured before and after treatment.)</p><p><b>RESULTS</b>After treatment, Hgb in the treated group and the control group was 108+/-5 g/L and 104+/-8 g/L respectively, showing marked improvement as compared with that before treatment (P<0.01), and the improvement in the former was more significant than that in the latter (P<0.05). Further, the level of T was also increased in the treated group after treatment (P<0.05), and showed a significant difference from that of the control group (P<0.05).</p><p><b>CONCLUSIONS</b>YXS capsule combined with RHE shows a better therapeutic effect in treating NA than that of RHE alone, and the effect might be through stimulation by YXS of erythropoiesis which could promote the secretion of testosterone.</p>

ABSTRACT

<p><b>OBJECTIVE</b>To assess the results of multi-technique with intact canal and scute rebuild operation for middle ear cholesteatoma.</p><p><b>METHODS</b>Analysis of 113 cases (males 60, females 53, with mean 42.7 years old), of which with double ears of 11 cases, and totally 124 ears (11 ears for one review, an ear for third time review, and totally 137 operations) was retrospectively performed. Ten cases less than 19 years old were operated from September 2001 to January 2006 for middle ear cholesteatoma as well as ossiculoplasty with intact canal and scute rebuild etc multi-technique. All cases were followed up for a mean (36.58 +/- 20.47) months.</p><p><b>RESULTS</b>There were 118 ears (95.2%) without cholesteatoma recurrence. Six ears were found cholesteatoma recurrence. Other 6 post-operation ears with drum re-perforation and hearing drop were re-operated. The pre-operation air-bone gap (ABG, average of 0.5, 1, 2 kHz) of 124 ears, with in initial 112 ears, was (33. 61 +/- 12.35) dB, while that of post-operation ABG was (13.58 +/- 9. 27) dB, by partnership t test, t = 18.35, P < 0.01. The pre-operation ABG in reviewed 12 ears at the first pre-operation was (38.83 +/- 12.43) dB, but post-operation ABG (10.38 +/- 8.99) dB, by partnership t test, t = 5.38, P = 0.00022. The ABG closure to within 20 dB was tested in 100 ears while ABG over 20 dB but air conduct (AC) in 40 dB was in 6 ears, and then as succeed was in 106 ears (85.5%). ABG closure within 10 dB was in 50 ears and though ABG over 10 dB but ABG reduced over 30 dB was in 9 ears (59/124, 47.6%) as which as best result. Bone conduct (BC) threshold was tested of 21 ears (16.93%) with raise 1-9 dB, of 42 ears (33.9%) with no change and of 61 ears (49.2%) with descend 1-28 dB. Of 10 cases less than 19 years old post-operation ABG was (8.80 +/- 5.27) dB, which indicated that all cases was as succeed.</p><p><b>CONCLUSIONS</b>Using intact canal and scute rebuild etc multi-technique a normal canal, hearing improvement and very low recurrent could be gained for middle ear cholesteatoma, especially in juvenile and children. The multi-technique should be almost no damage for hearing bone conduct.</p>
