ABSTRACT
AIM: To investigate the efficacy and safety of intravitreal injection of Conbercept combined with 25G minimally invasive pars plana vitrectomy(PPV)at the end of surgery for early proliferative diabetic retinopathy(PDR)with vitreous hemorrhage.METHODS: A total of 60 patients(60 eyes)with PDR complicated with vitreous hemorrhage requiring PPV at the Affiliated Eye Hospital of Nanjing Medical University were retrospectively analyzed. Based on the injection timing of Conbercept, the patients were divided into 3 groups: 20 patients(20 eyes)injected at the end of the surgery(group A), 20 patients(20 eyes)injected preoperatively(group B), and 20 patients(20 eyes)without injection(group C). The differences in pre- and post-operative visual acuity, intraocular pressure, intraoperative conditions, prognosis, and complications were analyzed among the 3 groups.RESULTS: There were no significant differences in the preoperative conditions and operation time among the patients. There was no iatrogenic retinal hole or silicone oil tamponade during the operation in the 3 groups, and no recurrent retinal detachment occurred after the operations. Best corrected visual acuity(BCVA)at 1, 3 and 6mo of all groups were improved compared with those before the surgery(P<0.05), and the injection groups(group A and group B)had a significantly better postoperative improvement than the non-injection group(group C), and there were significant differences(P<0.05). The incidence of postoperative late vitreous hemorrhage(1mo after operation)in group A was significantly lower than those in groups B and C(P<0.05). The central retinal thickness of the operated eyes in the injection groups(groups A and B)was significantly lower than that in the non-injection group(group C)at 1, 3 and 6mo after operation(P<0.05).CONCLUSION: Conbercept injection at the end of the surgery and preoperative injection are both safe and effective for early PDR and can significantly improve postoperative visual acuity. However, Conbercept injection at the end of surgery can reduce the risk of late vitreous hemorrhage recurrence, leading to better PPV outcomes and improving patients' retinal and visual function and quality of life.
ABSTRACT

ABSTRACT
Objective:Based on the holistic view of traditional Chinese medicine（TCM） and the characteristics of syndrome differentiation and treatment，methods of distance clustering and distance clustering combined with pseudo-bit clear（BIC） criteria are adopted in this study to simulate the doctor's clinical prescription process，and excavate a clinician's core prescription for the treatment of a specific disease. Method:In this study， it was believed that the clinical prescriptions of TCM can be divided into the core prescription for the treatment of the main syndrome and the addition and subtraction part of the medication for the concurrent syndrome. The hospital information system （HIS）was used to export the medical records of specific diseases，and then the methods of distance clustering and distance clustering combined with pseudo-BIC criteria were adopted to analyze professor WANG Jun-hong's 103 prescriptions for the treatment of Qi and Yin deficiency type of attention deficit hyperactivity disorder（ADHD）. The core prescriptions were screened by finding the optimal balance between the number of herbs and the proportion of population using the herbs. Result:Test4 consisted of 15 herbs such as Acori Tatarinowii Rhizoma，Crataegi Fructus，Lycii Fructus，Gall1 Gigerii Endothelium Corneum，and Pseudostellariae Radix were selected as the core prescription. In analysis by TCM theory and confirmation by professor WANG Jun-hong， it was proved to meet the characteristics of TCM treatment for ADHD. Conclusion:Combination of distance clustering with pseudo-BIC criteria method can effectively sort and screen the core clinical prescriptions of TCM，and compared with the current core prescription screening methods，it is characterized by conforming to the doctor's clinical prescription process. This research is helpful to provide certain support for inheriting the experience from famous TCM doctors and for the development of new Chinese medicines.
ABSTRACT
Objective::To explore the effect of Zuoguiwan on the bone mineral density (BMD) and the expressions of Ca2+ transport-associated protein in ovariectomized rats. Method::The 48 female SD rats were randomly divided into six groups: normal group, model group, sham operation group, estrogen group(0.167 mg·kg-1) and low and high-dose Zuoguiwan groups(9.6, 38.4 g·kg-1), with 10 rats in each group. Except for the sham-operated group, the ovariectomized rats in the other groups received the bilateral ovariectomy. Therapeutic intervention was given in each group for 3 months after the establishment of the model. After 12 weeks, BMD was measured using dualenergy X-ray absorptiometry. Tartrated presistant acid phosphatse(TRACP) and serum calcium were detected by biochemical kits.Protein expression in Ca2+ transport (Bone tissue) was detected by Western blot. Result::Compared with the normal group, the serum calcium of the model group was decreased(P<0.01). Compared with the normal group, BMD of the model group was decreased (P<0.01). The serum calcium of rats in high-dose group and western medicine group was higher than that of model group(P<0.01). BMD in model group was lower than that of Zuoguiwan groups and estrogen group(P<0.05). There was no significant difference in TRACP among the groups. Nilestriol and Zuoguiwan can down-regulate the expressions of TRPV5, NCX1, CaBP-D28K and PMCA1b in bone tissue of castrated rats(P<0.05, P<0.01). Conclusion::Zuoguiwan can down-regulate the expressions of Ca2+ transport-associated proteins (Bone tissues) in rat osteoclasts, with an efficacy on osteoporosis.
ABSTRACT
@#【Objective】To evaluate the effect of preoperative conjunctival sac irrigation with Anerdian Ⅲ disinfectant and its effect on the function of eye surface and tear film. 【Methods】 This clinical study was involved of thirty cases （30 eyes） undergoing phacoemulsification. Conjunctiva sac irrigation with Anerdian disinfectant （type III ，5g/L） was performed before the phacoemulsification procedure. Secretions of conjunctiva sac were examined by bacterial culture pre-and post-irrigation. Schirmer test，non-invasive first tear break-up time（NITBUT-F），non-invasive average tear break-up time（NITBUT-A），tear meniscus height（TMH），and goblet cell density（GCD）were also evaluated day 1 before and day 7 ，day 30 after operation.【Results】3 cases were positive in bacterial culture pre-irrigation ，while all were negative post-irrigation. There was no significantly change between Schirmer test and TMH from day 1 before ，day 7 and day 30 after operation . NITBUT-F，NITBUT-A，and GCD were significantly different between day 1 before and day 7 after operation（P<0.05），and shown no significantly difference between day 1 before and day 30 after operation.【Conclusions】 Our results suggested that conjunctiva sac irrigation with Anerdian disinfectant was efficient，while it might be related to the decrease of GCD and dysfunction of tear film. However，GCD would gradually improve as pre-operation and function of tear film could restore to normal.
ABSTRACT
@#【Objective】To detect the ability and the efficiency of recombinant PTD-HSP27 transport across RGC-5 cells and measure the role of recombinant PTD- HSP27 against oxidative stress damage induced by cobalt chloride on RGC- 5 cells，and explored its potential mechanism tentatively. 【Methods】 RGC- 5 cells were incubated with PTD- HSP27 labeled with FITC，followed by the observation of fluorescence using fluorescence microscope. We also lysed the cells by radio immunoprecipitation assay and measure the transport efficiency of PTD- HSP27- FITC through ultraviolet spectrophotometer subsequently. We established the RGC- 5 cell damage model. Cellular experiments were divided into three groups：normal control group，cobalt chloride damage group，PTD-HSP27 + cobalt chloride treatment group. Those three groups of cells were experimented using Annexin V- FITC/PI staining kit：to detect apoptotic cell ratio；Western Blotting：to detect the expression level of apoptosis related protein，including Bcl-2，Bax and Caspase-3.【Results】The fluorescence of PTD- HSP27- FITC was visualized inside the RGC- 5 cells using the fluorescence microscope，while the transport efficiency of PTD-HSP27-FITC was（47.29 ± 2.33）%. Cobalt chloride inhibited the survival vitality of RGC- 5 cells in a concentration- dependent manner. The comparison among normal control group，cobalt chloride damage group and PTD-HSP27+CoCl2 treatment group showed：PTD-HSP27 could effectively suppressed early apoptosis induced by cobalt chloride（P<0.01）. Western Blotting results showed that PTD-HSP27 could effectively enhance the expression ratio of Bcl-2/Bax，and suppressed the activation of Caspase- 3（P<0.01）.【Conclusions】Recombinant protein PTD- HSP27 could protect RGC- 5 cells against oxidative stress injury induced by cobalt chloride. Iit mainly regulated the expression ratio of Bcl-2/Bax，suppressed early apoptosis and improved cell viability in RGC-5 cells.

Antrodia camphorata, a well-known and highly valued edible medicinal mushroom with intriguing activities like liver protection, has been traditionally used for the treatment of alcoholic liver disease. A. camphorata shows highly medicinal and commercial values with the demand far exceeds the available supply. Thus, the petri-dish cultured A. camphorata (PDCA) is expected to develope as a substitute. In this paper, nineteen triterpenes were isolated from PDCA, and thirteen of them were the unique anthroic acids in A. camphorata, including the main content antcin K, which suggested that PDCA produced a large array of the same anthroic acids as the wild one. Furthermore, no obvious acute toxicity was found suggesting the edible safety of PDCA. In mice alcohol-induced liver injury model, triglyceride (TG), aspartate aminotransferase (AST), alanine aminotransferase (ALT), and malondialdehyde (MDA) had been reduced by the PDCA powder as well as the main content antcin K, which indicated that the PDCA could protect alcoholic liver injury in mice model and antcin K could be the effective component responsible for the hepatoprotective activities of PDCA against alcoholic liver diseases.

ABSTRACT
Traditional Chinese medicine (TCM) products are the finished products by adopting certain preparation processes according to the profile of the herbs, with Chinese herbs or decoction pieces as the raw materials.Among their adverse reactions to the organs, hepatotoxicity can not be ignored. As a new stage of quality control in TCM, dynamic quality control system of the multidemensional structure process emphasized on the research of the effectiveness and safety, focused on the pretreatment, preparation process,dosage forms and drug delivery methods to control the quality of TCM preparation products and reduce the generation of hepatotoxicity.In this paper, we will start from these factors to discuss the causes of hepatotoxicity underlying drug products and hope to provide the reference for developing low toxicity and high quality modern Chinese medicine products.
ABSTRACT
Idiosyncratic drug-induced liver injury (IDILI) is a kind of unique adverse drug reaction with relative high morbidity compared with other idiosyncratic diseases. Its occurrence, however, has nothing to do with pharmacological effects and clinical dosage of drugs administered, and only a small number of susceptible individuals will suffer from it. Especially to deserve to be mentioned, the proportion of TCM-induced IDILI showed an ascending trend year by year. So in this article, the author has reviewed some facts related with TCM-induced IDILI, including the predisposing causes and occurrence mechanism, and tries to provide reference for the prevention, diagnosis and treatment of TCM-induced IDILI through the analysis of characteristics and research status of TCM-induced IDILI and exploration of the internal relationship between Chinese medicine constitution type and IDILI.

ABSTRACT
In recent years, the proportion of traditional Chinese medicine in scientific research and its clinical use increased gradually. The research result also becomes more and more valuable, but in the process of using traditional Chinese medicine, it also needs to pay more attention. With the gradual deepening of the toxicity of traditional Chinese medicine, some traditional Chinese medicines have also been found to have the potential toxicity, with the exception of some traditional toxicity Chinese medicine. Traditional Chinese medicine in the growth, processing, processing, transportation and other aspects of pollution or deterioration will also cause the side effects to the body. Clinical practice should be based on the theory of traditional Chinese medicine to guide rational drug use and follow the symptomatic medication, the principle of proper compatibility. The constitution of the patients are different, except for a few varieties of traditional Chinese medicines are natural herbs with hepatotoxicity, liver toxicity of most of the traditional Chinese medicine has idiosyncratic features. The liver plays an important role in drug metabolism. It is easy to be damaged by drugs. Therefore, the study of traditional Chinese medicine potential liver toxicity and its toxic components has become one of the basic areas of traditional Chinese medicine research. Based on the review of the literatures, this paper summarizes the clinical classification of liver toxicity, the pathogenesis of target cell injury, and systematically summarizes the mechanism of liver toxicity and toxic mechanism of traditional Chinese medicine. This paper provided ideas for the study of potential liver toxicity of traditional Chinese medicine and protection for clinical safety of traditional Chinese medicine.
