ObjectiveTo study the effect of ultraviolet C(UVC) irradiation at different doses on expression of transforming growth factor β(TGF-β) of granulation tissues in wound. MethodsAfter dosing 15mJ/cm2 or 60mJ/cm2 UVC on wound of rats, the expression of TGF-β were observed at both the mRNA level and the protein level by the methods of in situ hybridization and immunohistochemistry respectively. Results At the 7th day after UVC irradiation, the expression of TGF-β in the 15mJ/cm2 group were higher than that in 60mJ/cm2 group and controls (P<0.05)at both the mRNA and the protein level. On the 21st day, the level of TGF-β mRNA in the 60mJ/cm2 group was higher than that in the other two groups(P<0.05).Conclusions At the early stage of wound healing,the treatment of 15mJ/cm2 UVC irradiation promots the expression of TGF-β and might be useful for accelerating wound healing. The level of TGF-β mRNA was up-regulated at the later stage at the dose of 60mJ/cm2 UVC irradiation.

On the basis of motor status of the frontalis musecle and the mouth corner 4 to 20 days after the onset, the degree and prognosis of facial paralysis of 218 cases were evaluated for 1~3 years. 44 cases belonged to neurapraxic type. In this type,visible motor recovery of frontalis and mouth corner was observed in 15 to 29 days after onset. Mild paralysis type (93 cases), in whom visible motor power of mouth corner appeared following the motor recovery of frontalis 14~20 days after onset, showed a total recovery in 24 to 40 days (84%). In moderate paralysis type, slight or absent visible motor recovery of frontalis was observed. Visible frontalis and mouth corner motor power appeared 20 days to 2 months after onset, with normal frontalis recovery in 42 cases.In 3 cases frontalis motor power recovered for 25% to 50%, and in 45 cases (67%) residual symptoms and complications were observed. Severe paralysis type consisted of 75% of patients, 36 patients, in whom the frontalis did not completely recover and 92% had residual symptoms and complications.Therefore, according to motor status of the frontalis and mouth corner, facial paralysis could be classified in predicting the prognosis.

Converting two poorly water-soluble crystalline drugs to co-amorphous drug systems by ball milling, quench-cooling, or cryo-milling method can improve stability of the drug, enhance dissolution rates, and reduce adverse reactions of the single drug. Co-amorphous system has been used to solve problems of co-administration of medicines. Formation and intermolecular interactions of co-amorphous drug systems may be verified by differential scanning calorimetry (DSC), X-ray powder diffraction (XRPD), Raman spectroscopy (RS) and Fourier transform infrared spectroscopy (FT-IR). Stability of co-amorphous drug systems is influenced by their glass transition temperature (Tg) and intermolecular interactions. The theoretical Tg values and the interaction parameter x are calculated by Gordon-Taylor equation and the Flory-Huggins equation, respectively. Thus, co-amorphous drug systems are analyzed theoretically at molecular level. Co-amorphous drug systems provide a new sight for the co-administration of medicines.

ObjectiveTo research the apoptosis of breast cancer cells by application of small direct-current electric field(EF) and its related possible mechanism.MethodsSmall direct-current EFs were applied in human breast cancer cell line MCF7 in vitro to observe the effects on apoptosis of cancer cells by terminal deoxynucleotidyl transferase-mediated dUTP nick end labeling(TUNEL)and to detect the mRNA expression of p53, Rb and E2F1 genes by reverse transcriptase-polymerase chain reaction (RT-PCR).ResultsA lot of cancer cells were observed slaughed from culture dish by 200mV/mm of the field strength and the number of the apoptotic cancer cells was gradually significantly increased with the application of EFs(P<0.01). mRNA expression level for p53 and Rb genes was elevated but that for E2F1 gene was decreased overtly in cancer cells exposed to EFs.ConclusionApoptosis of breast cancer cells can be induced by small direct-current EFs and the change for expression of p53, Rb and E2F1 genes may be involved in the mechanism.

ObjectiveTo observe the apoptosis of breast cancer cells induced by small direct-current electric field (EF) and its related possible mechanism in expression of p21 and p16 genes.MethodsSmall direct-current EF was applied in human breast cancer cell line MCF7 in vitro and the effect of EF on apoptosis and expression of p21 and p16 important genes of breast cancer cells was observed.ResultsThe small direct-current EF had an obvious apoptosis inducing effect on breast cancer cells. A lot of cancer cells were sloughed from culture dish by 200 mV/mm of the EF strength. The number of the apoptotic cancer cells was gradually significantly increased and mRNA expressions of p21 and p16 genes were raised following the EF strength being up (P<0.01).ConclusionThe small direct-current EF has an obvious apoptosis inducing effect on breast cancer cells. It may be related with the expression of p21 and p16 genes.

Objective To observe the long-term result of brachial plexus injury.Methods41 cases of brachial plexus injury were divided into the non-operation group (n=11), neurolysis group (n=17), never repair group (n=13). Retrospective analysis of the charts and follow-up survey of the functional recovery of shoulder joint and elbow joint were carried out. Gilbert score and Mallett score were adopted at the follow-up.ResultsIn the non-operation group, 9 cases were graded as excellent, 1 case as good, 1 case as bad. In the neurolysis group, 2 cases were graded as excellent and good. In the never repair group, 2 cases of shoulder joint obtained excellent, 4 cases of elbow joint were grade as good.ConclusionThe simple surgical result of brachial plexus injury is not satisfactory, it should be combined with postoperative rehabilitation.

ObjectiveTo investigate the L-hydroxyproline (L-Hyp) changes in rats' skin after exposed to different doses of ultraviolet C irradiation (UVC) and the effect of UVC radiation on collagen synthesis.MethodsAfter the animal model was set up, each male Wistar rat was made three fresh skin wounds, and three skin wounds of rats were divided into the 15 MED UVC irradiation (15mJ/cm2),60 MED UVC irradiation (60mJ/cm2) and control (without UVC irradiation). Then the chemistry method was utilized to research changes of L-Hyp contents of the granulation.ResultsFrom the 21st to the 28th day after UVC irradiation, contents of L-Hyp in the 15 MED group were higher than that in controls (P<0.05). While at the 28th day, L-Hyp level in the 60 MED group increased greatly and was higher than that in other two groups (P<0.01).ConclusionUVC irradiation increases L-Hyp level in rat's wound skin, so it accelerates the collagen synthesis and is helpful to promote wound healing, and the effect of 60 MED dose is superior to that of 15 MED.
