· Vascular endothelial growth factor is indispensable inducing factor in retinalangiogenesis. After the retinal neovascularization of proliferative diabetic retinopathy ( PDR ) patients, it can cause fibrovascular membrane formation, epiretinal membrane fibrosis increased, resulting in traction retinal detachment with further aggravate the condition. The recent research suggests that cytokines promote fibroblast proliferation, movement, adhesion, and secretion of extracellular matrix functions in the diabetic state of the environment changes to profibrogenic state, resulting in the accumulation and fibrosis of extracellular matrix. This paper reviewed the status quo of the correlation between vascular endothelial growth factor and fibrosis-related cytokine.

OBJECTIVETo provide a new material for producing the Rhodiolasachalinensis products, the effect of methyl jasmonate (MeJA) on callus biomass and effective compound accumulation of Rhodiolasachalinensis was studied.

METHODThe calluses-cultured in 3 L-air lift balloon type bioreactor were treated with MeJA after 20 d of bioreactor culture and the effect of MeJA concentration and treatment days on callus biomass, salidroside or polysaccharide accumulation and superoxide dismutase (SOD) and peroxidase (POD) activities were investigated.

RESULTThe callus biomass was not significantly different after MeJA treatment (125) for 0-6 d but obviously decreased after 6 d treatment. The maximum salidroside or polysaccharide contents and SOD or POD activities were found after 4 d treatment of MeJA. MeJA concentration significantly affected callus biomass and effective compound accumulation, biomass decreased at MeJA concentrations higher than 125 μmol x L(-1). However, the effective compound contents were determined at higher MeJA concentration, and the highest salidroside and polysaccharide accumulation was found at 225 and 275 μmol x L(-1) MeJA, respectively and the maximum SOD and POD activities was found at 225 μmol x L(-1) MeJA. The effective compound contents in callus were compared with field-grown plants. Salidroside contents in calluses were 1.1-fold and 2. 4-fold more than in plant roots and stem or leave, respectively. Polysaccharide content in calluses were 3. 6-fold and 8.0-fold more than in plant roots and stem or leave, respectively.

CONCLUSIONSalidorside and polysaccharide in Rhodiolasachalinensiscalluses improved by MeJA treatment, 225 μmol x L(-1) MeJA and 4 d treatment were optimal. The effective compound contents in callus were obviously higher than in field-grown plants. Therefore, bioreactor culture is efficient for obtaining mass effective compounds of Rhodiolasachalinensis by culturing calluses. This method could provide an alternative material source for production of Rhodiolasachalinensis products.

OBJECTIVETo evaluate the therapeutic effect on pain in the dressing change after perianal abscess surgery treated with warm suspending moxibustion at Changqiang (GV 1).

METHODSOne hundred and sixty patients were randomized into a moxibustion group and a far-infrared therapy group, 80 cases in each one. In the moxibustion group, the warm suspending moxibustion at Changqiang (GV 1) was applied. In the far-infrared therapy group, the infrared ray was radiated at Changqiang (GV 1). The treatment started in 10 min after dressing change in the two groups. Totally, 8 treatments were required. The time requirement being equal to or less than 2 score in the assessment face scale (AFS), the case number of pain relief in 10 min after treatment and the intention of the two therapies after everyday dressing change were observed in the patients of the two groups.

RESULTSIn the moxibustion group, the time of pain relief was shorter than that of the far-infrared therapy group [(11.5 +/- 3.9) min vs (17.8 +/- 3.8) min on the 1st day; (9.4 +/- 3.6) min vs (15.2 +/- 4.3) min on the 2nd day; (7.8 +/- 2.7) min vs (14.3 +/- 3.2) min on the 3rd day; (6.4 +/- 3.3) min vs (10.5 +/- 2.9) min on the 4th day; (5.9 +/- 2.9) min vs (11.2 +/- 1.9) min on the 5th day; (5.3 +/- 2.2) min vs (8.8 +/- 2.3) min on the 6th day; (5.4 +/- 1.8) min vs (9.2 +/- 2.1) min on the 7th day; (5.1 +/- 1.4) min vs (9.5 +/- 2.6) min on the 8th day, all P < 0.05]. The case numbers of pain relief in 10 min after treatment were 74 cases, 75 cases, 77 cases and 78 cases from the 1st to the 4th day separately in the moxibustion group, which were much more than 63 cases, 65 cases, 68 cases and 69 cases in the far-infrared therapy group (all P < 0.05). The treatment intention scores in the moxibustion group were better than those in the far-infrared therapy group (all P < 0.05).

CONCLUSIONThe warm suspending moxibustion at Changqiang (GV 1) relieves pain rapidly in the dressing change of much more patients after perianal abscess surgery in much shorter time as compared with the far-infrared therapy. Moreover, the patients have more expectation to be treated with moxibustion therapy.

OBJECTIVETo evaluate clinical efficacy of electroacupuncture at Changqiang (GV 1) and Chengshan (BL 57) 30 min before surgery on postoperative pain and discomforts in patients with mixed hemorrhoids.

METHODSOne hundred and twenty cases of mixed hemorrhoids who received Milligan-Morgan operation were randomly divided into an electroacupuncture group, a sham electroacupuncture group and a blank group, 40 cases in each one. At the same time of basic treatment, the electroacupuncture was applied at Changqiang (GV 1) and Chengshan (BL 57) 30 min before surgery in the electroacupuncture group, while shallow needling without electrical stimulation at sham acupoint (1 cm next to acupoint) was applied 30 min before surgery in the sham electroacupuncture group, while no treatment was given before the surgery in the blank group. The total dose of painkillers in the first 24 h after operation, the number of cases who received additional anesthetic in the operation, the self-score of most severity pain in the first 24 h after operation and sleeping time in the night of surgery were observed.

RESULTSThe differences of the numbers of cases who received additional anesthetic in the operation had no statistical significance among the three groups (all P > 0.05), but compared with the sham electroacupuncture group and blank group, the total dose of painkillers in the first 24 h after operation was reduced in the electroacupuncture group [(2.43 +/- 1.08) tablets vs (3.23 +/- 1.33) tablets, (3.10 +/- 1.22) tablets], and the score of most severity pain was also decreased (6.65 +/- 1.00 vs 7.48 +/- 0.96, 7.25 +/- 1.19), besides, the sleeping time in the night of surgery was increased [(220.63 +/- 85.50) min vs (162.00 +/- 92.69) min, (151.50 +/- 80.01) min, all P < 0.05].

CONCLUSIONThe electroacupuncture at Changqiang (GV 1) and Chengshan (BL 57) 30 min before surgery has effects of preemptive analgesia on postoperative pain for patients with mixed hemorrhoids.
