Objective To study the change tendency of air pollutants in Shenzhen, China in 2002-2005, further, to explore the relationship between disease spectrum and air pollution. Methods The daily mean concentration of SO2, NO2 and PM10 in 2002-2005 in eight environmental monitoring sites were determined according to Ambient Air Quality Standard. Results Air concentrations of SO2, NO2 and PM10 increased yearly in 2002-2004, from 0.018 3 mg/m3 to 0.023 4 mg/m3, 0.050 1 mg/m3 to 0.072 5 mg/m3, 0.061 0 mg/m3 to 0.075 7 mg/m3, respectively, however, the concentrations of the three indexes decreased in 2005. In the past four yeas, average levels of SO2 were under the limit of grade 2 of GB3095-1996, as for PM10, under the limit of grade 2, and most of the concentrations of NO2 were under the limit of grade 3, but in the other two monitoring sites, the concentrations of NO2 in 2004 exceeded the limit of grade 3. The year average concentrations of SO2, NO2 and PM10 in 2002-2005 in the outer region were higher compared with those in the inner region of the special economic zone, except the level of NO2 in 2002. As for the quarter average concentrations of SO2, NO2 and PM10, 1st and 4th were higher compared with 2nd and 3rd. Conclusion The air quality in Shenzhen is better in China, however, more attention should be paid to the pollution of nitrogen oxides and inhalable particle matters.

Objective To explore the clinical therapeutic effects of St. John's Wort exact (SWE)on depressive disorder and blood glucose in elderly type 2 diabetic patients Methods 118 patients with type 2 diabetes and depressive disorder were randomly assigned to SWE group (26 cases),lorazepam group (22 cases ), psychotherapy group (24 cases), physicotherapy group (24 cases) and control group (routine therapy,22 cases) for 12 weeks' treatment. The clinical effects were evaluated with the percentage reduction in HAMD score after the treatment, HbAlc levels were obtained to monitor glycemic control. Results (1) The percentage reduction in HAMD score in SWE group was the highest (80. 8%), and it was lower in lorazepam group ( 63. 6%), psychotherapy group (62. 5%) and physicotherapy group(58. 3%). The percent decrease in H AMD score was higher in four groups than in control group ( 18. 2%) and the difference was significant (P < 0. 01). The therapeutic effect of SWE was better than the others(P0. 05). (2) The level of HbAlc in SWE group (6.5±0. 6)% was significantly lower than the others [( 7. 5 ± 0. 8) %, (7.4 ± 0. 8) %, (7. 4 ±1.0) % (P < 0. 01 )]. Conclusions St. John' s Wort exact (SWE) can efficiently improve the depressive disorder in elderly type 2 diabetic patients, and it is good for controlling blood glucose of the patients.

Objective To investigate whether the macromolecular materials could enter cerebrospinal fluid and brain tissues in craniotomy with incision or non-incision of dura and arachnoid. Methods Adult male SD rats were randomly divided into three groups according to the random number table. The dura and arachnoid of rats in group A were cut open during craniotomy after general anesthesia; epidural craniotomy was done in rats in group B after general anesthesia; rats in group C (control group) were only generally anesthetized. All the rats were injected with Evans blue, a tracer used to detect the results, half an hour before each time point (1,3, 6, 12, 24, 72 hours and 1 week) via vein. The rats were executed at each time point to obtain the specimens of brain. The content of Evans blue in brain tissue was measured by fluorescence spectrophotometer for statistical analysis. The water content in the brain tissue was measured in a part of rats selected in groups A and B preoperatively and at postoperative 3 and 27 hours. Results It was found that some regions of the brain tissue were stained light blue in group A at 1,3, 6 and 24 hours. The blue was much lighter in brain tissue obtained at 72 hours in group A, and no blue stained at 1 week in group A . The contents of Evans blue in the brain tissues of rats in group A at 1,3, 6, 12, 24, 72 hours and 1 week were (18.07±1.25) μg/ml, (36.21±0.78) μg/ml, (25.73±1.14) μg/ml, (16.53±0.84) μg/ml, (23.34±1.91) μg/ml, (43.34±2.25) μg/ml and (25.27±1.88)μg/ml respectively, which were significantly higher than (3.15±0.45)μg/ml, (3.36±0.33)μg/ml, (2.98±0.54)μg/ml, (3.47±0.55)μg/ml, (3.54±0.37) μg/ml, (2.88± 0.42) μg/ml and (2.85±0.22) μg/ml respectively in group B and (2.97±0.37)μg/ml in group C (P<0.01). There was no significant difference in water content in brain tissue before and after operation (P>0.05). Conclusion After craniotomy with incision of dura and arachnoid, some macromolecular materials can enter the subarachnoid space and the brain parenehyma through blood-brain barrier of the wound of the scalp if the dura is sutured loosely.

Objective To investigate the long-term effect and radiation side reaction of different boost methods in patients with local remnants of locally advanced nasopharyngeal carcinoma after curative radiotherapy Methods Based on the retrospective analysis , 102 patients with local remnants of locally advanced nasopharyngeal carcinoma, after curative radiotherapy, were enrolled from February 2009 to May 2011. Forty-nine patients received gamma knife boost and 53 patients received 3-dimensional conformal radiotherapy (3D-CRT). The long-term effect and radiation side reaction were compared between the two groups. Results The 1-year, 3-year, and 5-year relapse-free survival rate (RFS) in the gamma knife boost group and the 3D-CRT group was 97.8%, 90.0%, 80.8%, and 94.3%,76.1%,72.9%, respectively (P < 0.05). No significant differences of the overall survival and metastasis-free survival rate wer found in two groups , as well as the long-term radioactive reaction. Conclusion The gamma knife boost is better than 3D-CRT with respect to local control rate , but the long-term radiation side reactions were similar between the methods.

OBJECTIVETo compare the radiation injuries of the temporomandibular joint (TMJ) following three-dimensional conformal radiotherapy (3D-CRT) and intensity-modulated radiotherapy (IMRT) in patients with nasopharyngeal carcinoma (NPC).

METHODSThirty-nine NPC patients without previous radiotherapy underwent 3D-CRT and another 32 received IMRT in our institute. The distance between the 2 dens incisivus medialis (DDIM) and LENT SOMA criteria were employed to evaluate TMJ injuries, clinical outcomes, and the performance-to-price ratios.

RESULTSThe short-term local response rates were similar between the two groups (P=0.878). The mean radiation doses of the TMJ were significantly higher in 3D-CRT group than in IMRT group (57.06 vs 40.90 Gy, P<0.001). The DDIM showed significant changes in 3D-CRT groups after the radiotherapy (P<0.05). No significant difference was found in the TMJ injuries between the two groups according to the SOMA criteria (P>0.05).

CONCLUSIONRadiation injuries of the TMJ are tolerable in both 3D-CRT and IMRT groups, and 3D-CRT is a more economic choice for patients who can not afford IMRT.

Objective:To compare the perioperative analgesic efficacy of ultrasound-guided serratus plane block (SPB) with pectoral nerves Ⅱ (Pecs Ⅱ) block in patients undergoing modified radical mastectomy for breast cancer under general anesthesia.Methods:Sixty female patients, aged 20-60 yr, of American Society of Anesthesiologists physical status Ⅰ or Ⅱ, scheduled for modified radical mastectomy for breast cancer, were divided into 2 groups ( n=30 each) using a random number table method: SPB group (group S) and Pecs Ⅱ block group (group P). Both groups received ultrasound-guided nerve block with 0.5% ropivacaine 20 ml before induction of general anesthesia.The patients in both groups received patient-controlled intravenous analgesia.Tramadol 100 mg was intramuscularly injected as rescue analgesic.The block status of each segmental dermatome, comsumption of intraoperative remifentanil and analgesics (sufentanil in patient-controlled intravenous analgesia and rescue analgesics) within 24 h after operation, duration of nerve block, Horner syndrome, and complications such as respiratory depression, nausea and vomiting within 24 h after operation were also recorded. Results:Compared with group S, the block rate of T 5-T 7 dermatome and consumption of sufentanil after surgery were significantly decreased ( P<0.01), and no significant change was found in the consumption of remifentanil and duration of nerve block in group P ( P>0.05). No rescue analgesic was used and no nerve block-related complications and postoperative complications were found in either group. Conclusions:The ultrasound-guided Pecs Ⅱ block provides better efficacy than SPB in the patients undergoing modified radical mastectomy for breast cancer under general anesthesia.

Abstract According to the Healthy China Action Plan, Wuhan gives full play to the role of preventing and controlling student myopia by promoting student health. The primary focus is placed on education in schools, and Wuhan has integrated educational resources to develop a multi-level myopia prevention and control system and service network for school students. The network contains educational adminstrative, schools, families, and professional technical service organizations. By integrating multiple disciplines, Wuhan has built a comprehensive vision health management service system for all students. The Internet and cloud intelligent monitoring facilitated the establishment of a smart vision health management platform for students, which thoroughly and efficiently implemented myopia prevention and control to safeguard students visual health by engaging in education, monitoring, and supervision. The prevention and control of student myopia is a breakthrough for comprehensive healthy development of students. A comparison of the standard myopia rate in Wuhan in 2019 and 2018 revealed that the standard myopia rate at different learning stages of primary school, junior high school, and high school dropped by 3.31, 2.50, and 2.26 percentage points, respectively, and the rate of myopia in primary school was significantly lower than the national level. Post-epidemic surveys showed that the compliance rate and the awareness rate of the visual environment and visual behaviors of primary and secondary school students in Wuhan reached more than 80%, and prevalence of newly onset myopia or decreased vision was 30%, which was lower than the national average. The "Wuhan Model" provides an important referential framework for public health services for school students.
