OBJECTIVETo investigate the effect and safety of extracorporeal shock wave (ESW) in the treatment of pain symptom of type III B prostatitis.

METHODSWe treated 50 cases of type III B prostatitis by ESW once a week for 4 weeks. Then we evaluated the clinical effect and safety of the therapy based on the NIH-CPSI scores, visual analogue scale (VAS) scores, IIEF-5 scores, prostate volume and morphous, state of urination, color of urine, results of routine semen analysis, and changes of cytokines (IL-6, TNF-α and IL-1β) in expressed prostatic secretion (EPS).

RESULTSAll the patients successfully accomplished the treatment. Compared with the baseline, decreases were observed after 4 weeks of cytokine treatment in the pain scores (14. 61 ± 1. 82 vs 9. 36 ± 1. 47, P <0. 01), urination symptom scores (4. 59 ± 1. 01 vs.4. 66 ± 0. 89, P >0. 05) , quality of life scores (6. 51 ± 1. 03 vs 4. 56 ± 1. 02, P <0. 01), NIH-CPSI (25. 43 ± 1. 72 vs 18. 28 ± 2. 32, P <0. 01 ), and VAS (6. 59 ± 1. 10 vs 3. 02 ± 1. 07, P < 0. 01). The concentration of IL-6 in the EPS was significantly increased ([55.82 ± 6. 28] vs [86.59 ± 4. 55] ng/ml, P <0. 01) , while the level of TNF-α ([3.89 ± 0. 12] vs [3. 19 ± 0.22] ng/ml, P<0.01) and that of IL-1β ([3.21 ± 1.01] vs [1.48 ± 0.95] ng/ml, P< 0. 01) remarkably reduced after treatment. However, there were no statistically significant differences in IIEF-5 scores (18. 58 ± 2. 03 vs 18. 51 1. 89, P >0. 05) or various sperm parameters before and after treatment (P >0. 05). And no significant changes were observed in the prostate volume, morphous or internal echoes.

CONCLUSIONThe ESW therapy is effective and safe for the pain symptom of type III B prostatitis.

Proteolytic degradation has been a severe problem when Pichia pastoris is employed to express recombinant proteins.One alternative method to circumvent this problem is to construct protease gene disruptant.However,the main study of gene disruption is focused on nonrecombinant Pichia pastoris rather than recombinant strain.In our study,we established two different methods to directly disrupt PRC1 and KEX1 gene in recombinant Pichia pastoris.On the basis of this,we further discussed and compared the application and advantages of both methods.

Objective To assess the effectiveness of prevention program on iodine deficiency disorders and iodine nutritional status of residents in Guangdong Province.Methods Probability proportionate to size sampling(PPS) was employed in surveillance of iodine deficiency disorders.Thirty counties(cities,districts) were selected in Guangdong Province.In each county(city,district) one township(street) was selected; in each township (street) one primary school was selected and in each primary school 40 children aged 8-10 were chosen to examine their thyroid and to collect salt samples at their home for determination of salt iodine.Out of the 40 children,12 children were chosen to collect urine samples for determination of urinary iodine.From the primary schools chosen,40 grade 5 students were selected for intelligence quotient(IQ) test.In the nearby of the primary schools,3 townships(towns,street) were selected and in each township(town,street) 5 pregnant and 5 lactating women were selected to collect their urine samples for determination of urinary iodine.Type-B ultrasonic was used in measuring the thyroid volume.The iodine content of urine samples was measured by the method of arsenic and cerium catalysis spectrophotometry.The iodine content of salt was determined quantitatively with the titration method.IQ was tested by Chinese combined Raven's test.According to geographical location and the implementation of iodized salt,the effects of iodized salt on iodine deficiency disorders were analyzed in the plains and the Pearl River Delta Coastal region with mild iodine deficiency(iodized salt implementation region,referred to as the plains and the PRD),historical iodine deficiency areas (iodized implementation region) and the eastern and the western coastal areas of Guangdong(areas with non-iodized salt problem,referred to as the eastern and the western Guangdong).Results A total of 1200 children aged 8 to 10 were examined by type-B ultrasonic test,and goiter rate was 3.5％ (42/1200).The differences of goiter rate between the plains and the PRD,the historical iodine deficiency areas and the eastern and the western Guangdong were statistically significant (x2 =6.6,P ＜ 0.05).The goiter rate (6.1％) in the eastern and the western Guangdong was significantly higher than that of the plains and the PRD and the historical iodine deficiency areas (3.3％,2.0％,x2 =5.6,7.1,all P ＜ 0.05).A total of 1200 salt samples were examined.The median and coefficient of variation of iodine in the salt were 31.0 mg/kg and 23.2％,respectively.Coverage of iodized salt was 97.5％(1170/1200) while 96.1％(1153/1200) of consumed iodized salt was qualified.The median urinary iodine of 1200 children aged 8-10 was 186.5 μg/L,and the differences of median urinary iodine between the plains and the PRD,the historical iodine deficiency areas and the eastern and the western Guangdong were statistically significant(x2 =5.9,P ＜ 0.05).The median urinary iodine of the eastern and the western Guangdong(162.4 μg/L) was significantly lower than that of the plains and the PRD(207.5 μg/L,x2 =8.7,P ＜ 0.01).The difference of median urinary iodine between the plains and the PRD,the historical iodine deficiency areas and the eastern and the western Guangdong was statistically significant(x2 =58.9,P＜ 0.01).The median urinary iodine of the eastern and the western Guangdong(109.6 μg/L) was significantly lower than that of the historical iodine deficiency areas and the plains and the PRD(152.9,155.2 μg/L,x2 =18.3,20.6,all P ＜ 0.05).The mean IQ of the 1208 grade 5 students was 102.8 ± 14.3.The IQ of the plains and the PRD(104.3 ± 13.9) and the historical iodine deficiency areas(102.7 ± 14.3) was significantly higher than that of the eastern and the western Guangdong(100.3 ± 14.7,t =3.8,2.1,P＜ 0.01 orP＜ 0.05).Conclusions The goal of iodine deficiency disorders elimination is achieved as scheduled in Guangdong Province.The health level of general population has been improved significantly.Iodine nutrition is in the appropriate range (100-199 μg/L) in general population but low in pregnant women.The selling of non-iodized salt in the eastern and the western Guangdong Province should be followed closely.

OBJECTIVETo investigate the possible mechanism of the electroacupuncture for improvement of learning and memory in rats of Alzheimer's disease (AD).

METHODSSixty Wistar rats were randomly divided into a normal group, a normal saline group, a model group, a western medication group and an electroacupuncture group, 12 rats in each group. The AD rat model was established by injecting Streptozocin (STZ) into lateral cerebral ventricle, except the rats in the normal saline group injecting Normal Saline with the same dose and in normal group with no injection. The western medication group was treated with intragastric administration of Memantine, and in the electroacupuncture group, the electroacupuncture was given at "Baihui" (GV 20), "Dazhui" (CV 14), "Taixi" (KI 3), "Shenshu" (BL 23), "Zusanli" (ST 36), once each day, 7 days for a course, and lasted for 4 courses. The other three groups were fed in routine way and without any treatment. The learning and memory ability was assessed by Morris water maze and the expression of Abeta positive cells of the hippocampus and superoxide dismutase (SOD) activity were determined by immunohistochemistry and visible spectrophotometer colorimetry.

RESULTSCompared with the normal group and the normal saline group, the Abeta protein expression was significantly increased in the model group (both P < 0.01), and the SOD activity was obviously decreased (both P < 0.01). After treatment, as compared with the model group, the Abeta protein expression was significantly decreased (both P < 0.01), and the SOD activity was obviously increased (both P < 0.01) in the electroacupuncture group and western medication group.

CONCLUSIONElectroacupuncture treatment can reduce the Abeta protein expression and increase the SOD activity of the hippocampus so as to improve learning and memory ability in the AD rats.

BACKGROUND: The effect of pituitary adenylate cyclase activating polypeptide (PACAP) during traumatic brain injury (TBI) and whether it can modulate secondary injury has not been reported previously. The present study evaluated the potential protective effects of ventricular infusion of PACAP in a rat model of TBI. METHODS: Male Sprague Dawley rats were randomly divided into 3 treatment groups (n=6, each): sham-operated, vehicle (normal saline)+TBI, and PACAP+TBI. Normal saline or PACAP (1g/5L) was administered intracerebroventricularly 20 minutes before TBI. Right parietal cortical contusion was produced via a weight-dropping method. Brains were extracted 24 hours after trauma. Histological changes in brains were examined by HE staining. The numbers of CD4+ and CD8+ T cells in blood and the spleen were detected via flow cytometry. RESULTS: In injured brain regions, edema, hemorrhage, inflammatory cell infiltration, and swollen and degenerated neurons were observed under a light microscope, and the neurons were disorderly arrayed in the hippocampi. Compared to the sham group, average CD4+ CD8– lymphocyte counts in blood and the spleen were significantly decreased in rats that received TBI+vehicle, and CD4– CD8+ were increased. In rats administered PACAP prior to TBI, damage was attenuated as evidenced by significantly increased CD4+, and decreased CD8+, T lymphocytes in blood and the spleen. CONCLUSION: Pretreatment with PACAP may protect against TBI by influencing periphery T cellular immune function.
