Glioblastoma is a malignant tumor in central nervous system, which has strong invasion, poor prognosis and short survival time. At present, the main treatment strategy of glioblastoma is surgical excision, supplemented by radiotherapy and chemotherapy. However, due to incomplete resection and high recurrence rate, it is urgent to find novel therapeutic method for glioblastoma. Photodynamic therapy, as a promising non-surgical treatment, provides a new strategy for postoperative adjuvant therapy of glioblastoma. This review summarizes the mechanism and clinical application of photodynamic therapy mediated by various photosensitizers in glioblastoma, in order to provide help for the treatment of glioblastoma.

OBJECTIVETo observe the therapeutic effects of shoulder-elbow elastic immobilization and functional exercise for injured shoulder arthrochalasis, and compare it with forearm-suspending immobilization and functional exercise therapy.
METHODSThe patients with injured shoulder arthrochalasis were randomly divided into treatment group (38 cases) and control group (37 cases). Treatment group underwent the therapy of shoulder-elbow elastic band immobilization and functional exercise; control group was managed by forearm-suspending band immobilization and functional exercise therapy.
RESULTSIn treatment group, 29 (76.3%) cases recovered, 7 (18.4%) improved and 2 (5.3%) failed; in control group, 15 (40.5%) cases recovered, 15 (40.5%) cases improved and 7 (19.0%) failed. The differences between two groups were statistically significant (P<0.01). The AHI (acromio-humeral interval) ranged from 8 to 19 mm (11.9+/-5.1) in treatment group and 8 to 27 mm (14.2+/-5.4) in control group, and the difference was also statistically distinct (t=2.7525, P<0.01).
CONCLUSIONThe treatment with shoulder-elbow elastic band immobilization and exercise therapy for injured shoulder arthrochalasis is a safe and effective method. Immobilization with shoulder-elbow elastic band is better than forearm-suspending band for injured shoulder arthrochalasis.

HIV/STIs remain a major global public health problem. One of the global strategies for the prevention and control of HIV/STIs is to interrupt their transmission, which requires the public health methods based on scientific evidence and cost-effectiveness. The scale-up of male circumcision services in the priority countries of the HIV-prevention project in sub-Saharan Africa has been hampered by the scarcity of trained providers and relative technical difficulty of male circumcision techniques recommended by WHO and UNAIDS. Shang Ring is an innovative and disposable device for male circumcision, which has been safely used for over 600 000 males in China since 2006. Clinical studies of more than 3 000 cases of Shang Ring circumcision in China, Kenya, Zambia, and Uganda have demonstrated its safety, effectiveness, acceptability and ease of use. The most obvious advantages of Shang Ring include short procedure time (3-6 min), excellent postoperative cosmesis, low rate of complications, high acceptance by clients and providers, ease of use, and standardization for reliable performance. As an innovative technique, Shang Ring has a great potential for facilitating the safe and effective scale-up of circumcision services. This article comprehensively reviews the clinical studies of Shang Ring male circumcision in China and Africa.

To study the B cell linear epitopes of rabies virus CVS-11 nucleoprotein, peptides were synthesized according to the amino acid sequences of B cell linear epitopes. Linear epitopes predicted by bioinformatics analysis were evaluated with immunological techniques. Indirect enzyme-linked immunosorbent assay showed that titers of antibodies to peptides (355-369 and 385-400 residues of rabies virus CVS-11 nucleoprotein) were above 1:12 800 in mouse sera. The antibodies recognized denatured rabies virus CVS-11 nucleoprotein in Western blot analysis. Purified anti-peptide antibodies recognized natural rabies virus CVS-11 nucleoprotein in BHK-21 cells in indirect fluorescent antibody test. The 355-369 and 385-400 residues of rabies virus CVS-11 nucleoprotein were validated as B cell linear epitopes.

Objective To evaluate the efficacy and side effects of adjuvant chemotherapy plus in-tensity modulated radiotherapy (IMRT) after breast-conserving surgery for stage Ⅰ and Ⅱ breast cancer.Methods After breast-conserving surgery, 108 patients received six cycles of chemotherapy followed by IM-RT. The irradiation dose of the whole breast was 50 Gy given by 25 fractions, followed by 10 Gy boost to the tumor bed given by 5 fractions with electron beams. Patients with positive estrone receptor or progesterone re-ceptor were given endocrine treatment, mostly with tamoxifen. Results The follow-up rate was 100% by December 2007. The number of patients followed-up at 1-, 2- and 3-year was 108,88 and 58. The 1-, 2- and 3-year over survival rates were 100% ,100% and 98%. Three patients had local recurrence. Different degree of dermatitis occurred with good long-term cosmetic results. No severe side effects occurred such as radiation-induced pneumonitis, pulmonary fibrosis and heart injury. Conclusions Breast cancer patients treated by adjuvant chemotherapy plus IMRT after breast-conserving surgery have high survival rate and low side-effect rate. The survival quality and local control can be improved.

OBJECTIVETo study the correlation factors of acute paraquat intoxication prognosis.
METHODSThe early paraquat concentration in plasma and urine, leukocyte count, hepatic and renal function, amylase, electrolyte and the parameters of arterial blood gas were analyzed retrospectively in 111 patients with acute paraquat intoxication.
RESULTS43 cases (38.7%) of all the 111 patients survived and the other 68 cases (61.3%) died. The patient, whose paraquat concentration was not more than 8.0 µg/ml in plasma and 276.0 µg/ml in urine, could survive. But some patients could die, only if there was no paraquat found in plasma. The paraquat levels in plasma and urine were significantly lower in survivors [(0.82 ± 1.70), (28.12 ± 51.17) µg/ml] than in nonsurvivors [(9.32 ± 12.04), (384.53 ± 597.93) µg/ml, respectively] (P < 0.01). The levels of leukocyte count, serum creatinine, aspartate aminotransferase (AST), and amylase were significantly higher in nonsurvivors than in survivors (P < 0.05, P < 0.01). In addition, metabolic acidosis was easier to appear in nonsurvivors. The multiple logistic regression analysis indicated that the paraquat concentration in plasma and urine, leukocyte count, creatinine and base excess were all related to survival.
CONCLUSIONThe higher paraquat concentration in plasma and urine, leucocytosis, renal dysfunction and metabolic acidosis are all important factors for the prognosis of paraquat intoxication.

OBJECTIVETo investigate the effects of procyanidins on proliferation and apoptosis of a hormone-dependent prostate cancer cell line LNCaP in vitro.
METHODSLNCaP cells were cultured in the presence of procyanidin (at 100, 200 and 300 microg/ml, respectively). After 24, 48 and 72 h of culture, the morphological changes of LNCaP cells were examined, and the inhibition of cell proliferation was measured by MTT assay and cell apoptosis evaluated by flow cytometry.
RESULTSAfter procyanidins treatment, some LNCaP cells presented characteristic morphological changes. Procyanidins inhibited the growth of LNCaP cells in a concentration- and time-dependent manner. Flow cytometry analysis showed that procyanidins induced apoptosis of LNCaP cells and the percentage of apoptotic cells increased with the concentration of procyanidins administered and also the elongation of treatment time.
CONCLUSIONProcyanidins inhibit the proliferation and promote the apoptosis of prostate cancer cells.

OBJECTIVETo observe the changes in the activity of dendritic cells (DCs) after carcino-embryonic antigen (CEA) gene transfection mediated by recombinant adeno-associated virus type2 (rAAV) and tumor cell lysate.
METHODSImmature DCs isolated from peripheral blood monocytes of HLA-A11-positive healthy volunteers were infected with the rAAV carrying CEA gene or loaded with tumor cell lysate. The surface markers of the DCs such as CD40, CD 1alpha, and CD86 were analyzed by flow cytometry. Interleukin-12 (IL-12) in the supernatants of DCs and interferon-gamma (IFN-gamma) released by the cytotoxic T lymphocytes (CTLs) were determined by ELISA detection kit. The specific killing activity of CTL against LoVo cells was assessed by MTT assay.
RESULTSThe DCs following antigen loading with the two methods both highly expressed CD40, CD86 and IL-12, and induced specific CTL that specifically recognized and killed LoVo cells, but the killing effect resulting from rAAV infection of the DCs was much better than that induced by tumor cell lysate loading.
CONCLUSIONBoth methods of antigen loading can induce mature DCs from peripheral blood monocyte cells, but rAAV infection of the DCs can be more effective than tumor cells lysate loading. DCs infected with rAAV may have the potential to serve as an adjuvant immunotherapy for patients with colorectal carcinoma.
