Radiotherapy is an important treatment for malignant tumors, but it will have a negative impact on the reproductive function of young female patients.In recent years, the measures to protect female fertility are increasing, including clinical mature technologies such as embryo cryopreservation and mature oocyte cryopreservation; highly experimental technologies such as immature oocyte in vitro fertilization and ovarian tissue cryopreservation and transplantation.In addition, the application of stem cells and the proposal of artificial ovary also show great prospects in the protection of female fertility.This paper reviews the research progress of female fertility protection strategies in radiotherapy.

By using a self-developed IF power and a ASTM contact material experimental system of small-capacity and variable frequency, the value of arcing characteristics and the welding force of the silver-based contact material are acquired under low voltage, resistive load and small current at 400 Hz and 50 Hz. By means of an electricity-ray analytical balance, SEM and EDAX, the weighing values of the contact materials and the changes of AgCdO, AgNi, AgC and AgW contact material surface profile and micro-area constituent are obtained and analyzed. The arc erosion causes of silver-based alloy contact materials at 400 Hz and 50 Hz are also discussed.

IgG4 related disease (IgG4-RD) is a systemic disease which was named and accepted in recent years.IgG4-RD is a multiorgan-involved disease, mainly including pancrease, parotid gland, bile duct, liver, etc.The study on the relationship between IgG4 and orbital disease is relatively few.In recent years, our study group aimed directly to the relationship between IgG4 and common orbital disease, including benign lymphoepithelial lesion of lacrimal gland,idiopathic orbital inflammatory pseudotumor, orbital lymphoma, etc.We found that IgG4 was associated with the pathogenesis and progression of these diseases.This article addressed systematically the pathogenesis of IgG4 related orbital disease and evaluated the values of IgG4 in diagnosis,differential diagnosis,treatment and montoring of these orbital diseases based on related literature and reseaching results from our study group,in order to deepen the recognition of IgG4 related orbital diseases in ophthalmologists.

To investigate the expression of vascular endothelial growth factor (VEGF)and the levels of reactive oxygen species (ROS)in human mesangial cells cultured in high glucose and being intervened by pigment epithelium-derived factor (PEDF). The results showed that with increased glucose concentration, the expressions of VEGF and ROS generation also gradually increased and PEDF significantly downregulated VEGF expression and ROS generation in a dose-dependent manner. PEDF may delay the diabetic nephropathy progress by improving vascular permeability and inhibiting oxidative stress.

OBJECTIVETo observe the therapeutic effect of a drug pair of Radix Astragali and Rehmanniae Radix combined with glucocorticoid (GC) in treating lupus nephritis (LN) patients and its influence on some experimental indices.

METHODSTotally 52 LN patients were randomly assigned to the treatment group (treated by routine Western medicine and a drug pair of Radix Astragali and Rehmanniae Radix, 25 cases) and the control group (treated by Western medicine, mainly by GC and cyclophosphamide, 27 cases). All patients received 6-month therapy. The GC dosage, the withdrawal and reduction dosage of GC, clinical efficacy, systemic lupus erythematosus disease activity index (SLEDAI) score, adverse reactions, and laboratory indicators were recorded.

RESULTS(1) All patients got relieved to some degree with the dosage of GC reduced. The total withdrawal and reduction dosage of GC was slightly higher in the treatment group than in the control group [(50.23 +/- 12.43) mg vs (48.76 +/- 13.61) mg, P > 0.05]. Besides, the prednisone dosage in the treatment group was lower than that in the control group, but without statistical difference (P > 0.05). The ratio of patients in need of adding prednisone for aggravating disease was 24.0%, significantly lower than that in the control group (44.44%, P < 0.05). (2) There was no statistical difference in the SLEDAI score, inflammatory indicators, liver and renal functions, blood electrolytes, blood glucose, blood and urine routines between the two groups (P > 0.05). The 24-h urinary protein count was (1.06 +/- 0.22) g/L in the treatment group, obviously lower than that in the control group (1.43 +/- 0.55 g/L, P < 0.05). (3) There was no statistical difference in the incidence rate of infection, gastrointestinal hemorrhage, psychoneuroses, Cushing's syndrome, cardiovascular anomalies, and femoral head necrosis between the two groups (P > 0.05). But the incidence of adverse reactions such as insomnia, tidal fever, spontaneous sweat, and obesity was less in the treatment group than in the control group (P < 0.05).

CONCLUSIONSUsing a drug pair of Radix Astragali and Rehmanniae Radix combined with GC in treating LN could withdraw the dosage of GC and relieve symptoms it induced. It was advantageous in reducing the dosage of GC and stabilizing patients' conditions.

In the therapeutic application of head and neck squamous cell carcinoma ( HNSCC),S-1 is used to combine with other chemotherapeutics or even with radiotherapy to constitute chemoradiotherapy regimens.Adverse effects are well tolerated.Regimens containing S-1 are wildly used to control distant metastasis as well as local recurrence.The studies of treatment also show good application value.

Objective To investigate the relaxant effect of salanic acid A isopropyl ester(isopropyl 3-(3,4-dihydroxyphenyl)-2-hydroxypropanoate)and its mechanism.Methods Isolated rat pulmonary artery was perfused and the tension of the vessel was measured.To observe the relaxant effect of salianic acid A isopropyl ester on the pulmonary artery precontracted by noradrenaline(NE)and the role of endothelial cell and vascular smooth muscle cell on vasodilation.Results Salianic acid A isopropyl ester relaxed the endothelium-intact artery precontracted by NE in a concentration-dependent manner,and the effect was depressed with denuded endothelium.Salianic acid A isopropyl ester right-shifted the concentration-response curve of KCl and suppressed the contractions induced by NE and CaCl2 in the Ca2+-free-K-H solution.The relaxant effect of salianic acid A isopropyl ester was inhibited by N?-nitro-L-arginine methyl ester hydrochloride(L-NAME),Indometacin,CsCl,Tetraethylammonium(TEA),Glibenclamide,and BaCl2,but not that by Propranolol,Metoprolol,and Salbutamol.Conclusion Salranic acid A isopropyl ester could significantly relax the pulmonary artery of rats,which may derive in part from endothelium.The relaxant effect of salianic acid A ispropyl ester may relate to NO pathway,prostacyclin(PGI2)pathway,calcium channel,and potassium channel.

Cases with coronary heart disease after successful PTCA were selected for observation of the preventive' action of CXZP on restenosis of the vessel. Results revealed that (1) In the western medicine group 15 cases experienced recurrent angina pectoris. Among them, 12 cases received repeated angiography, 11 of them were confirmed to have restenosis while the 3 other cases were positive in ECG exercise treadmill test. No obvious changes were observed in stasis integration before and after treatment (P

Objective To study the clinical efficacy of Wenweinjiangni granule combined with allantoin aluminum on patients with peptic ulcer and the changes of serum gastrin,transforming growth factor-α(TGF-α)and interleukin-8(IL-8)to explore the best treatment for patients with peptic ulcer.Methods 86 patients with peptic ulcer admitted in our hospital from July 2014 to July 2015 were selected as subjects of this study.The control group was treated with allantoin aluminum,and the observation group was treated with Wenweijiangni granule combined with allantoin.The serum levels of Gas,TGF-α,IL-8,adverse reaction and therapeutic effect were observed in the two groups.Results After treatment,the levels of Gas and IL-8 in the observation group were significantly lower than those in the control group [(68.96±21.26)pg/mL vs.(82.75±24.08)pg/mL(6.93±2.31)μg/L vs.(5.06±2.07)μg/L,(11.86±2.10)μg/L vs.(14.97±2.76)μg/L](P<0.05).The total incidence of side effects in the observation group was less than that in the control group(6.97％vs.23.25％)(P<0.05).The total effective rate of the observation group was better than that of the control group(95.34％vs.76.74％)(P<0.05).Conclusion The combination of Wenweijiangni granule and allantoin aluminum can improve the ulcer surface of patients with peptic ulcer,improve Gas,TGF-α and IL-8,which is more effective and more effective than aluminum allantoin alone.
