Objective To investigate the correlation of epidermal distribution of lamellar bodies and expression of ceramidase with skin barrier dysfunction in polymorphous light eruption.Methods Forty-seven patients with polymorphous light eruption and 40 healthy volunteers were recruited into this study.Noninvasive instruments were used to measure skin sebum content,transepidermal water loss(TEWL)and water content in stratum corneum in all of the subjects.Then,tissue specimens were obtained from the lesions at sunexposed sites in the patients and normal skin of the healthy volunteers.The ultrastructure and distribution of lamellar bodies were observed with transmission electron microscopy in five lesion and control specimens.Immunohistochemistry was performed to detect the expression of ceramidase in the tissue specimens.Results Compared with the normal skin from healthy volunteers,the lesions from patients showed decreased number of lamellar bodies in the granular layer and prick cell layer with a disorganized arrangement.Ceramidase was positively expressed in 20 lesion specimens and 36 normal control specimens,weakly expressed in 21 lesion specimens and 4 normal control specimens,and negative in 6 lesion specimens; there was a significant difference in the expression of ceramidase between the lesion specimens and normal control specimens(P ＜ 0.01).The lesions also showed high TEWL(34.2191 ± 12.70 vs.16.8350 ± 6.50,P ＜ 0.01),lower water content in stratum corneum(22.7319 ± 8.71 vs.29.4250 ± 5.08,P ＜ 0.01)and similar skin sebum content compared with the normal skin.Conclusions There is a disturbance in the synthesis of ceramide in patients with polymorphous light eruption,which may contribute to the impairment of skin barrier.

Background Trans-corneally subretinal injection in rodent model is a useful method for genetic therapy,stem cell transplantation and the study on the ophthalmic research.Standarized operation process is critical for the successful treatment.However,there is no literature to report the detailed procedure and the influence of this technique on morphology and function of retina.Objective This sudy was to introduce a method of trans-corneally subretinal injection and evaluate its influence on the morphology and function of retina.Methods Trans-corneallly subretinal injection was performed on the left eyes of 2-month-old SPF C57BL/6J mice after dilation of pupils.A 301/2G disposable needle was used to puncture the cornea within the pupil area near limbus and avoid touching the lens and irises under eye surgery microscope.Then,a 33G blunt needle was used to insert into the vitreous and toward subretinal space via corneal puncture.Normal saline with 0.1％ fluorescein sodium of 1 μl was slowly injected into the space,and 2.5％ hydroxypropyl methylcellulose was dropped on ocular surface for the observation of the fundus clearly.According to the percentage of the retina filled with subretinally injected solution,the experimental eyes were divided into 80％-100％ area group,50％-70％ area group after injection,and the mice in the pseudo-injected group,in which injection procedure stopped just before the solution was pushed in to the subretinal space did not inject any solution after punctured.The right uninjected eyes of the mice served as normal control group.Four eyes were selected for each group.The structural changes were evaluated by optical coherance tomograpby (OCT) 1 day,2 days,3 days and 5 weeks after injection,and retinal function was assessed by the recored of electroretinography (ERG) 5 weeks after injection.The retinal sepcimens were prepared to examin the morphological changes by hematoxylin and esosin staning.The use of care followd the Regulations for the Administration of Affair Concerning Experimental Animals of Zhejiang Province.Results About 70％ of the injected eyes showed that retinal blebs filled with injected green fluorescein solution occupied 50％ or more retinal area with minimal damages.The focal detachment between neurosensory retinal layer and retinal pigment epithelium (RPE) was exhibited 1 day postinjection,and almost all the retinas retached 2 days after injection.In the fifth week after injection,the amplitudes of ERG b wave were (386.25±37.88),(357.50±41.03),(324.25±53.45) and (410.50±14.88) μV in the sham operation group,50％-70％ area group,80％-100％ area group and normal control group,respectively,showing a significant difference among the 4 groups (F=3.574,P=0.047),and the amplitudes of b wave in the normal control group were higher than those in the 80％-100％ area group (all at P ＜ 0.05).The detachment between retinal neuroepithelium layer and RPE layer,cell proliferation and transposition in the outer nuclear layer were dispalyed under the light microscope in the sham operation group,50％-70％ area group and 80％-100％ area group,and the disordered outer segment of photoreceptors at the injecting area was seen in the 50％-70％ area and 80％-100％ area groups at five weeks after injection.However,retinal sructure and morphology were normal at the non-injection area.Conclusions Trans-corneally subretinal injection is an effective and safe way for subretinal injection.

Wound healing is a complex and highly regulated process to maintaining the skin barrier function. Wounds of diabetic patients are hard or even not healing. Non-healing diabetic foot ulcers can lead to lower-extremity amputations. Diabetic wound healing problem is the main complication that leads to high disability rate of diabetes and can threaten the lives in severe cases. The healing of skin wounds requires the synergy of multiple factors to restore the injured skin to its barrier function. The mechanisms that cause it difficult to heal diabetic wounds are complex, including oxidative stress, chronic inflammation, decreased neovascularization, peripheral neuropathy, and imbalance of extracellular matrix accumulation and remodeling. This review classifies mechanisms of diabetic wound healing and provides a reference for its further research.

OBJECTIVETo observe mainfestations of syndrome and biochemical indices of hypertensive model rats with excessive accumulation of phlegm-dampness syndrome (EAPDS), and to explore its possible pathological mechanism.

METHODSEAPDS rat model was prepared in 50 Wistar rats by feeding with high fat forage. Meanwhile, a normal control group consisting of 10 Wistar rats was set up by feeding with normal forage. After 25-week continuous feeding, 22 rats with body weight (BW) and blood pressure (BP) exceeding 25% those of the control group were selected as a model group. BW, BP, blood lipids, and related serological indicators were detected in all rats. Morphological changes of target organs were observed. mRNA expression levels of leptin receptor (LepR), Janus kinase2 (Jak2), signal transducer and activator of transcription 3 (Stat3), suppressor of cytokine signaling-3 (Socs3), angiotensin II receptor type 1 (AT1), angiotensin II receptor type 2 (AT2), phosphatidylinositol 3 kinase (P13K), serine threonine kinase (Akt), nuclear factor of kappa B (NF-κBp65), inhibitor of nuclear factor kappa-B kinase α (IKKα), NF-kappa-B inhibitor β (lKKβ), NF-kappa-B inhibitor α (IKBα), and AMP-activated protein kinase (AMPK) were detected by quantitative real-time PCR (qPCR). Expression levels of AT1 and LepR in aorta were detected by immunohistochemical assay and Western blot respectively.

RESULTSCompared with the control group, BW, BP, and blood lipids increased; serum levels of leptin (Lep) , Ang II, Hcy, ET-1, TNF-α, IL-6, and p2-MG increased, but NO decreased in the model group (P < 0.05, P < 0.01). Aortal endothelial injury and smooth muscle cell proliferation occurred in the model group, accompanied with heart and renal injury. Compared with the control group, mRNA expression levels of LepR, Jak2, Stat3, Socs3, AT1 , PI3K, Akt, NF-κB p65, IKKβ, IKBα, and AMPK in aorta were up-regulated significantly (P < 0.05), while the expression of IKKa decreased (P < 0.05). Immunohistochem- ical staining showed, brownish yellow deposit of AT1 and LepR was obviously increased, with more extensively positive distribution. Western blot results showed, as compared with the control group, protein expression levels of AT1 and LepR obviously increased in the model group (P < 0.05).

CONCLUSIONSModel rats exhibited typical syndromes of EAPDS. They put up weight with fat abdomen, gloomy hair, poor appetite, hypersomnia, lowered activities , reduced food intake, loose stool, dark red tongue, white tongue with white, thick, greasy fur. Lep could be taken as one of objective indicators for evaluating hypertension rat model with EAPDS.

OBJECTIVETo study the clinical efficacy of the laparoscopic surgery in combination of Quyu Jiedu Recipe (QYJDR) on endometriosis (EMs)-related infertility patients.

METHODS130 EMs-related infertility patients of blood stasis and toxin accumulation syndrome diagnosed and treated by laparoscopic surgery were randomly assigned to two groups, i.e., the test group (75 cases) and the control group (55 cases). All patients received routine progesterone treatment after laparoscopic surgery. QYJDR was given to patients in the test group after laparoscopic surgery, lasting for twelve months. The pregnancy rate within one year after laparoscopic surgery were compared between the two groups. The Chinese medicine syndrome integrals, serum endometrium antibody (EMAb) and cancer antigen 125 (CA125) levels were compared between before drug therapy and three months after drug therapy.

RESULTSThe pregnancy rate within one year after laparoscopic surgery was higher in the test group than in the control group [61.33% (46/75) vs 45.45% (25/55)], showing significant difference (P<0.05). The Chinese medicine syndrome integral was (16.07 +/- 6.77) score and (7.25 +/- 3.27) score before and 3 months after drug therapy in the test group, while it was (15.92 +/- 7.51) score and (12.73 +/- 6.12) score in the control group. The Chinese medicine syndrome integral after drug therapy was lower than that before drug therapy in the same group. Besides, the integral difference between before and after drug therapy was higher in the test group than in the control group [(9.12 +/- 6.16) score vs (3.48 +/- 2.06) score)], showing statistical difference (P<0.05). After three-month drug therapy, the serum EMAb negative conversion rate was obviously higher in the test group than in the control group (44.44% vs 15.62%), showing statistical difference (P<0.05). The serum CA125 level was (31.88 +/- 15.78) U/mL before drug therapy and (18.82 +/- 10.08) U/mL three months after drug therapy in the test group, while it was (30.63 +/- 19.28) U/mL and (18.05 +/- 11.20) U/mL respectively in the control group. It was lowered after drug therapy in the two groups with statistical difference (P<0.05). There was no statistical difference between the two groups after drug therapy (P>0.05).

CONCLUSIONSThe laparoscopic surgery in combination of QYJDR could effectively improve clinical symptoms of EMs patients of blood stasis and toxin accumulation syndrome, promote negative conversion of EMAb, lower serum CA125 levels, and elevate the clinical pregnancy rate. QYJDR is an effective formula in treatment of EMs-related infertility.
