To analyze the clinical characteristics and combined use of chemical and traditional Chinese medicine (TCM) medicine of hospitalized patients with psoriasis base on real world database, 2 991 cases of hospitalized patients with psoriasis in hospital information system (HIS) database from 16 hospitals in China were analyzed for general hospitalization information, combined diseases and combined use of drugs et al. The results showed that half of inpatients aged 18-45 years old. The most common syndrome of TCM was intrinsic blood heat. More than 1/3 inpatients' hospitalization time was 18-25 days, and the average expense of hospitalization was 6 989. 20 RMB. The top five combined diseases were hypertension, non-alcoholic fatty liver disease, diabetes, upper respiratory tract infection and lipoprotein disorders. Medicine information analysis showed 599 chemical medicines and 341 TCMs were used and combined use of drugs was common in clinical practice. Licorice extract medicine was the most common combined TCM with western medicine; in the next two places were compound Qingdai capsule and tripterygium glycosides. The most common combined use of chemical medicines were Vitamin C, calcium gluconate, ketotifen, cetirizine, retinoic acid and external use glucocorticoid. Anti-inflammatory and liver protection, clearing heat and toxic materials, activating blood and dissolving stasis were the most common combined TCM medicine with western medicine, while the most common combined chemical medicine with TCM were anti-allergic, anti-infection, glucocorticoid and retinoic acid. In conclusion, half of hospitalized patients of psoriasis were young adults. The main type of combined diseases was metabolic disorders and upper respiratory infections. Combined use of chemical medicine and TCM was common in clinical practice. Licorice extract medicine was the most common combined TCM with western medicine.

Objective: To assess the effectiveness and security of autologous platelet-rich gel (APG) in the treatment of refractory diabetic dermal ulcers., Methods: Thirteen diabetic patients with refractory skin lesions were enrolled for this study, and APG was produced by platelet (PLT)-rich plasma (PRP) with thrombin and calcium gluconate. APG treatment consisted of wound dressed with APG, followed by topical washing and cleaning. The APG was then covered with Vaseline gauze and left for 48 to 72 hours, after which the wounds were treated conventionally until the next PLT-gel treatment. The clinical endpoints of the study were the healing rate., Results: A total of 13 patients entered the pilot study. There were no drop-outs in the study. 69.2% ulcers were cured, and especially the ulcer areas were reduced significantly in the first 3 weeks; no adverse reactions were observed., Conclusion: Topical therapy with APG may be considered as an effective adjuvant method to treating refractory diabetic dermal ulcer.

Objective: To compare the effects of different kind of methods in the management of hydrofluoric acid burn in early postburn stage in rabbits., Methods: Thirty-three rabbits were inflicted with burn by 55% of hydrofluoric acid covering 5% TBSA, and were randomly divided into 3 groups, i.e. A (n = 13, with 5 ml.kg(-1).h(-1)of isotonic saline intravenous infusion), B (n = 10, with isotonic saline and 50 g/L of calcium gluconate infusion in dose of 20 mg/kg at different time points), and C (n = 10, with the same treatment as B group, and with excision of burn wound at 0.5 post burn hour) groups. The serum levels of fluorine and calcium were determined before and after various postburn hours, and the mortality rate was statistically analyzed., Results: (1) The serum level of fluorine in A (8.37 +/- 2.62 mg/L) and B (8.59 +/- 2.25 mg/L) groups reached the peak value at 1 postburn hour (PBH), which was 107 times higher than that before the burn injury. The serum level of fluorine in B group was significantly lower than that in A group at 24 PBH (P < 0.05), while that in C group declined to (6.20 +/- 0.23) mg/L, which was obviously lower than that in A and B groups (P < 0.01). (2) The serum calcium level declined after burns, reaching the lowest level at 8 to 12 PBH. and began to increase at 24 PBH. Compared with normal calcium value, the serum level of calcium in A, B and C groups declined to as much as 46%, 32% and 26%, respectively. Statistically significant difference was found between C and B groups (P < 0.01). (3) The mortality rate in the three groups within 72 PBH were 30.8%, 12.5% and 0.0%, respectively., Conclusion: Early removal of burn area and calcium supplementation could help quickly decrease blood fluorine, reverse the fatal hypocalcemia and the multiple systemic toxic injury in rabbits inflicted with hydrofluoric acid injury.

Objective: To investigate the mechanism of hemorrhagic tendency after phosphorus poisoning., Methods: 45% phosphoric acid and 20 mg/cm2 phosphorus were used to produce burn injury in rabbits. The total content of phosphorus remaining on the wound and 7-day mortality were similar in both groups., Results: The results showed that plasma free calcium contents were significantly lower in both phosphorus groups than healthy and thermal burn controls (0.80 vs 1.40 mol/l, P < 0.01). The free calcium content of platelet was lowered to 116-140 nmol/l, which was significantly lower than that of healthy control (285 nmol/l) and thermal injury group (480-504 nmol/l). Concomitantly, the platelet aggregation rate was lowered to 1.29% and 10.78% in phosphoric acid group and phosphorus group, respectively, while it was 67.01% in healthy control and 82.1%-84.9% in thermal injury group; the difference was statistically significant., Conclusion: Calcium therapy brought back intracellular and extracellular free calcium contents to normal in phosphorus burn group. Also platelet aggregation rate approached normal level after calcium therapy. The results suggest that the bleeding tendency after phosphorus burn is due to combination of phosphorus with intracellular and extracellular calcium of platelets, thus inhibiting aggregation of platelets.

20 patients with phosphor burn (TBSA 2%-75%) were cured by i.v. drop of calcium gluconate combined with other therapies including eschar conservation. Our experimental data showed that dogs with burn by spreading 85% phosphoric acid and napalm locally increased the level of plasma phosphorus and pathological damages to the heart, lung, kidney and etc were similar to those previously reported phosphorus burns. Intravenous drop of calcium gluconate after phosphate burn reduced the level of plasma phosphorus to normal rapidly and lessened the visceral damages. We consider that i.v. drop of calcium gluconate can accelerate the elimination of phosphorus, and prevent phosphorus poisoning after phosphorus burns.

All of 20 patients with phosphorus burn, admitted from 1987 to 1991, have been cured by intravenous drip of calcium gluconate combined with other therapies. The wounds were washed with tap water, followed by eschar formation in 12 days. The clinical data showed that phosphorus poisoning did not occur if calcium was given very early postburn. Calcium also could abolish or ameliorate clinical manifestations of existing phosphorus poisoning, accelerate the elimination of phosphorus and recovery of damaged organs.
