OBJECTIVETo report the effect of Fengweicao Granule (FWCCG), a Chinese herbal preparation made of herba Pteris multifidae, in treating benign prostatic hyperplasia (BPH).

METHODSOne hundred and fifty-five patients were assigned to two groups, the 108 patients in the treated group were administered orally with FWCG twice a day, 5 g every time; the 47 patients in the control group were treated with Proscar 5 mg per day for 3 months. The effects were evaluated by the change of the related indexes before and after treatment, including scoring by international prostatic symptom scale (I-PSS), maximum flowing rate of urine (MFR), residue urine volume (RU) in urinary bladder determined by abdominal B-ultrasonography and volume of prostate.

RESULTSAfter being treated for 3 months, the I-PSS, MFR and RU improved remarkably in both groups (P <0.05 or P <0.01), but with no significant change in the volume of prostate, neither with significant difference in comparison between the two groups (P >0.05).

CONCLUSIONFWCG has a good effect with less adverse reaction in treating BPH.

Objective To investigate the effect of seafood intake on the urinary iodine level in women for exploring an alternative to iodine supplementation.Methods Healthy pregnant women and non-pregnant women, aged 20～40 years,were selected during their health examination in local women'S health care in 2006.The types of seafood and its intake frequency were recorded from these women.and urine and kitchen salt samples were collected for iodine determination.Results A total of 198 women including 148 pregnant and 50 non-pregnant women were recmitod for this study;they had a median level of urine iodine of 87.51 mg/L.The median levels of urine iodine of83.49,91.52,166.45μg/L in three group women classified as hardly,seldom and often intake of see food showed significant difference(X2=6.202,P<0.05).Urine iodine level in non-pregnant women taking seafood (90.94μg/L)was higher than that in pregnant women(84.79μg/L),the difference being statistically significant (U=3318.00,P<0.05).The urine iodine in pregnant women with seldom intake of seafood(94.46 μg/L)was significantly higher than that in the hardly intake women(83.28 μg/L),the difference being statistically significant (U=1257.5,P<0.05).During late period of gestation,the urinary iodine in the women ofthree statUS of hardly. Seldom and often intake of seafood were 81.93,97.97 and 140.18 μg/L,respective,with significant differences among them.Conclusions A certain amount of seafood taken every week Can increase urine iodine levels,and a direct relationship Was observed.Therefore,we suggest that it is necessary to advocate taking seafood to pregnant women for prevention of cretinism,particularly in the air.as where iodized salt was difficult to implement.

Objective To explore the epidemics of influenza viruses in Guangzhou area from 1998 to 2003. Methods The specimens for viral isolation were taken with swabs from children's throats and the material was inoculated into the MDCK cells and were incubated at 33 ℃ The supernatant of MDCK cells culture was tested with hemagglutination test. Results Influenza viruses were isolated from 264 of 3444 children; total positive rate of influenza virus isolation was 7.6%. The positive rate of influenza viruses was 16.8% in 1998; the prevailing strain of influenza viruses was H3N2. The influenza viruses isolation rate was 7.4% in 1999;the positive rate was 8.4% ; HIN1 occurred in 2000, the positive rate was 3.8%. H3N2 did not occur in 2001; the positive rate was 7.3% ; influenza B viruses was the prevailing strain in 2002; the positive rate was 1.7% in 2003. Influenza B viruses was Yamagata like strain from 1998 to 2001, Victoria like strain from 2002 to 2003. H9N2 avian influenza virus was isolated from a child. Conclusions Influenza was prevalent in Guangzhou in 1998, but not prevalent from 1999 to 2003. Most of influenza B viruses were Yamagata strain. There were cases avian influenza caused by H9N2 in 1999.

OBJECTIVETo develop and investigate GLL-37, a substitution analogue of the human antimicrobial peptide LL-37 with anti-enzymatic degradation activity and improved efficacy.

METHODSThe bactericidal activities of LL-37 and newly developed GLL-37 against 6 Gram-negative and -positive bacteria were determined by Broth microdilution assays. The minimum inhibitory concentrations of LL-37 and GLL-37 against E.coli ATCC 25922 in different NaCl concentration medium were also detected. Both peptides were co-incubated with elastase, and then analyzed by PAGE electrophoresis and bactericidal activity determination.

RESULTGLL-37 showed a stronger elastase resistance ability than LL-37, and was significantly more effective than LL-37 under high-salt condition.

CONCLUSIONThe antimicrobial peptide GLL-37 derived form LL-37 has the potential as a new therapeutic agent for bacterial infections.

OBJECTIVETo develop the techniques of total hip arthroplasty(THA) for Crowe type IV developmental dysplasia of the hip (DDH) with S-ROM prosthesis,and to assess its clinical results.

METHODSFrom October 2000 to October 2011,30 patients (36 hips) with Crowe type IV DDH underwent THA,including 6 patients with bilateral hip involved and 24 patients with unilateral. S-ROM prosthesis was adopted together with subtrochanteric transverse osteotomy. All the cementless acetabular cups were placed at the original anatomic location. The threaded cups were put in or near the level of the true acetabulum in all patients. Full coating stems were used in femoral side. All the patients were evaluated by using the Modified Harris Hip Score. Radiographic evaluations were made preoperatively and during follow-up.

RESULTSTwo patients lost of follow-up. Twenty-seven patients with 32 hips were followed up,and the average duration was 48 months (ranging from 7 to 84 months). There was 1 patient with bilateral THA died from hemorrhagic shock. Two patients could walk freely with the visible fracture lines at 12th and 18th months postoperatively. There were no complications such as infection or nerve injuries. Modified Harris Hip Score improved from preoperative 41.7+/-3.7 to postoperative 89.1+/-2.9. There was no acetabular or femoral component revision because of mal-position or loosening of the prostheses in all patients. Postoperative X-ray showed that all the prostheses in place,good integration between acetabular cups,femoral prosthesis and host bone without loosening. All bone grafts were integrated. All the hips acquired union of osteotomy and bone in-growth. None of the patients had radiographic evidence of aseptic loosening of prosthesis.

CONCLUSIONFor the complex DDH, follow methods should be used to improve therapeutic effects:good exposure of the true acetabulum,deepen acetabulum, femoral shortening, oblique osteotomy, using the S-ROM prosthesis.

OBJECTIVETo investigate the analgesic effect of interleukin-2 (IL-2) in mice with spared nerve injury (SNI).

METHODIL-2 was intraperitoneally injected in mice with induced SNI, and von Frey Filaments test and cold plate test were carried out to accesses the analgesic effects of IL-2 and the effect of naloxone in antagonizing the effects of IL-2.

RESULTSIL-2 produced analgesic effects against hyperalgesia and allodynia in mouse models of SNI, and the effect of IL-2 lasted for more than 24 h, showing a double-peak pattern in its action with the two peaks occurring at 30 and 105 min, respectively. The effect of IL-2 could be significantly antagonized by naloxone.

CONCLUSIONSIL-2 has long-lasting analgesic effects in mouse models of SNI model, showing a double-peak pattern of its action. The analgesic effect of IL-2 is probably mediated by opiate receptor.

BACKGROUND: Visual-spatial neglect (VSN) is a neuropsychological syndrome, and right-hemisphere stroke is the most common cause. The pathogenetic mechanism of VSN remains unclear. This study aimed to investigate the behavioral and event-related potential (ERP) changes in patients with or without VSN after right-hemisphere stroke. METHODS: Eleven patients with VSN with right-hemisphere stroke (VSN group) and 11 patients with non-VSN with right-hemisphere stroke (non-VSN group) were recruited along with one control group of 11 age- and gender-matched healthy participants. The visual-spatial function was evaluated using behavioral tests, and ERP examinations were performed. RESULTS: The response times in the VSN and non-VSN groups were both prolonged compared with those of normal controls (P < 0.001). In response to either valid or invalid cues in the left side, the accuracy in the VSN group was lower than that in the non-VSN group (P < 0.001), and the accuracy in the non-VSN group was lower than that in controls (P < 0.05). The P1 latency in the VSN group was significantly longer than that in the control group (F[2, 30] = 5.494, P = 0.009), and the N1 amplitude in the VSN group was significantly lower than that in the control group (F[2, 30] = 4.343, P = 0.022). When responding to right targets, the left-hemisphere P300 amplitude in the VSN group was significantly lower than that in the control group (F[2, 30] = 4.255, P = 0.025). With either left or right stimuli, the bilateral-hemisphere P300 latencies in the VSN and non-VSN groups were both significantly prolonged (all P < 0.05), while the P300 latency did not differ significantly between the VSN and non-VSN groups (all P > 0.05). CONCLUSIONS Visual-spatial attention function is impaired after right-hemisphere stroke, and clinicians should be aware of the subclinical VSN. Our findings provide neuroelectrophysiological evidence for the lateralization of VSN.

Objective To investigate the hope level and its influencing factors in chronic obstructive pulmonary disease(COPD)patients.Methods Questionnaires were randomly applied to investigate the hope level and its influencing factors of 76 patients with chronic obstructive pulmonary disease with acute exacerbation (AECOPD).Results The hope level scores were in the range of 21-45 interval,and the mean score was (34.92 ±4.89).97.37％ of AECOPD patients were in mid-high level.Univariate analyses showed that family relationship,monthly salary,activities of daily living(ADL),disease severity were influential factors(P＜0.05).HHI of AECOPD with different respiratory training was different(F =3.76,P ＜ 0.05),and the score of those never exercise was(34.29 ±5.12),(37.08 ± 1.00)in those exercise more often,and(41.50 ±3.54)of those exercise every day.HHI of patients with different oxygen-intake time was different(P ＜ 0.01).Multivariate multiple linear regression analysis showed that monthly salary and ADL were influential factors,and the more salary,and the more hope-level.ADL,oxygenintake time month salary,and disease severity were related to hope-level of patients by multivariate analyses in oxygenintake patients(P ＜ 0.01).Conclusions For nursing care of the COPD patients,attention should be paid on improving the hope level,interfering in the correlated influencing factor as soon as possible so as to continuously improve the quality of life.

OBJECTIVEChildren aged 3 - 6 years in the urban areas of China were surveyed for the first time to find out the state of child neglect (CN) as well as the major relevant risk factors so as to provide evidence for developing intervention measures.

METHODS1163 children (of whom 49.6% were males and 4.5% were minority nationality) were randomly sampled under multistage stratification, from 25 cities which representing 15 provinces of China. Based on the Child Neglect Norms used by China, prevalence of CN was identified and SPSS-Windows 11.0 was employed for statistical analysis. Scores, frequency/degrees, age, sex and 5 types (physical, emotional, educational, medical and safety) of CN on every group of the regions, were calculated. Multifactorial analysis was conducted through Binary Logistic Regression and multiple linear regression to determine the relevant risk factors.

RESULTS(1) The average degree of CN for the 3 - 6 year-olds was 42.2, with its prevalence as 28.0%. Degrees of CN for the groups of 3, 4, 5, 6-year-olds were 41.7, 42.2, 42.1 and 43.1 (F = 0.988, P > 0.05), with frequencies of 25.0%, 25.3%, 27.9% and 35.4% (chi(2) = 4.798, P > 0.05), respectively. Degrees for CN in males and females were 42.7 and 41.8 (F = 2.502, P > 0.05) with the frequencies as 32.6% and 23.7% (chi(2) = 6.585, P < 0.05), respectively. Degrees of CN for the five types were 39.4-43.4 with the frequencies as 5.1%-12.9%, respectively. No significant difference was found in the frequency of the types (with an exception on 'physical neglect') between males and females (P > 0.05). The highest frequency (42.9%) of CN was seen in the single-parent families and the lowest in large family with three generations (25.5%). (2) According to monofactorial chi(2) test, the possible risk factors of CN would include: educational background, occupation and decrease of income of the parents during last year, etc. (3) Binary Logistic regression analysis showed that the influential factors to the occurrence of CN would include: father's educational background, sex of the child and mother's occupation, etc. (4) Multiple linear regression showed that the influential factors to the degree of CN were: family structure, number of supporting family members, relationship between parents and children, etc.

CONCLUSIONThe degree and frequency of CN among children aged 3 to 6 in the urban areas of China were high but similar among the four age groups. Male children had a higher frequency of neglect than females, but with similar degree. Children in single-parent families had the highest frequency. The major influential factors of CN would include: educational background, occupation, family structure, family income of the parents which were similar to the results reported from foreign literature.

OBJECTIVETo explore clinical efficacy of hip replacement for hip-joint diseases with Parkinson disease.

METHODSFrom December 2011 to December 2016, 18 patients with hip-joint diseases with Parkinson disease treated by hip replacement, including 8 males and 10 females aged from 59 to 87 years old with an average of 71 years old. Among them, 3 cases were developmental dysplasia of hip, 3 cases were femoral head necrosis and 12 cases were femoral neck fracture. All patients manifested with obvious pain and limitation of stepping ability. Postoperative complications were observed and Harris score were used to compare hip joint function after operation.

RESULTSThe incision were healed well, and pain were alleviated or disappeared, and hip joint function were improved. Eighteen patients were followed up from 1 to 3 years with an average of 2.3 years. At the latest follow up, 14 cases recovered freedom-walk, 2 cases could walk with walking stick, 1 case could walk with walking aid and 1 case was died. Among 18 patients, 2 cases were occurred dislocation, and 1 case were died for cardiac disease at 3 months after operation. Four patients were occurred slight pain. There were significant differences in Harris scores among preoperative (41.7±1.4), 6 months after operation(80.1±5.4) and the final follow-up (83.4±2.1), and 10 cases got excellent result, 4 good, 1 fair and 2 poor.

CONCLUSIONSApplication of hip replacement for hip-joint diseases with Parkinson disease is a safe and effective clinical therapy, and has advantages of less complications and rapid recovery of hip joint function.
