Objective:To investigate the masticatory function and the expression of monocyte chemoattractant protein-1 (MCP-1) and tumor necrosis factor-α(TNF-α) in gingival crevicular fluid.Methods:The clinical data of 98 patients with dentition loss admitted to Tongxiang First People′s Hospital from June 2017 to June 2019 were analyzed, and 49 cases were treated with oral implant repair(observation group) and 49 cases were treated with conventional repair(control group). Both groups were followed up for 6 months. The masticatory function, speech function, retention function, quality of life and the changes of MCP-1 and TNF-α in gingival crevicular fluid were compared before treatment and 6 months after treatment.Results:The total effective rate of the observation group was higher than that of the control group: 95.92%(47/49) vs. 79.59%(39/49), and the difference was statistically significant ( χ2=6.078, P<0.05). At 6 months after treatment, the scores of masticatory function, speech function and retention function in the observation group were higher than those in the control group ( P<0.05). The scores of emotional function, social function and physiological function in the observation group were higher than those in the control group ( P<0.05). The levels of MCP-1 and TNF-α in gingival crevicular fluid of the observation group were lower than those of the control group: (32.09 ± 7.65) μg/L vs. (43.62 ± 9.23) μg/L, (2.19 ± 0.38) μg/L vs. (3.20 ± 0.51) μg/L, and the differences were statistically significant ( P<0.05). Conclusions:Dental implant repair is effective for patients with dentition loss, and it can improve masticatory function and quality of life, and reduce the expression of MCP-1 and TNF-α in gingival crevicular fluid.

BACKGROUND: Recently, a few studies have reported the correlation between transforming growth factor-α (TGF-α) and graft-versus-host disease (GVHD); however, the combination of TGF-α with other cytokines in patients with chronic or acute GVHD requires further study.OBJECTIVE: To analyze the changes of serum tumor necrosis factor-α (TNF-α), interleukin-4 (IL-4), and transforming growth factor-α (TGF-α) in leukemic patients after allogeneic hematopoietic stem cell transplantation (Allo-HSCT) and investigate the effects of these cytokines on different grades of GVHD.DESIGN: Case control study.SETTING: Department of Hematology, Organ Transplantation Center, the Second Affiliated Hospital, General Hospital of Chinese PLA; Department of Nuclear Medicine, the Second Affiliated Hospital, General Hospital of Chinese PLA.PARTICIPANTS: Forty-two leukemic patients (23 males and 19 females, 16-68 years old, mean age of 35 years) who underwent Allo-HSCT for the first time were selected from the Department of Hematology, Organ Transplantation Center, the Second Affiliated Hospital, General Hospital of Chinese PLA and Department of Transplantation, the 307 Hospital of Chinese PLA from June 2005 to June 2007. Twelve patients had acute granulocytic leukemia (AGL), fifteen patients had acute lymphocytic leukemia (ALL), and fifteen patients had chronic granulocytic leukemia (CGL). Among the 42 patients, 37 underwent peripheral blood transplantation and five received bone marrow transplantation. Twenty-one patients had acute GVHD (18 cases in grades Ⅰ-Ⅱ and three cases in grades Ⅲ-Ⅳ) after Allo-HSCT, but the other 21 patients did not. Fourteen patients had chronic GVHD (five cases of limited type and nine cases of extensive type), but the other 28 patients did not. An additional 30 healthy subjects (18 males and 12 females, 20-70 years old, mean age of 44 years) were collected as a normal control group. All patients provided confirmed consent, and the study was approved by the local ethics committee.METHODS: Levels of serum TNF-α, IL-4, and TGF-α in leukemic patients with Allo-HSCT and normal subjects were measured by radio-immuno-assay, the cytokines levels of the patients with/without acute GVHD, of those with/without chronic GVHD and of different grades of GVHD were compared.MAIN OUTCOME MEASURES: Comparisons of serum TNF-α, IL-4, and TGF-α among the groups.RESULTS: All 42 leukemic patients and 30 healthy subjects were included in the final analysis. Levels of TNF-α, IL-4, and TGF-α in patients with acute or chronic GVHD were significantly higher than those in the normal subjects (P<0.05-0.01). Levels of TNF-α and IL-4 in patients without acute GVHD were significantly higher than those in the normal subjects (P<0.01,0.05). Levels of TNF-α, IL-4, and TGF-α in patients with acute GVHD were significantly higher than those in patients without acute GVHD (P<0.05). Levels of TNF-α, IL-4, and TGF-α in patients with chronic GVHD were significantly higher than those in patients without chronic GVHD (P<0.05). Levels of serum TNF-α and TGF-α in patients with acute GVHD of grades Ⅲ-Ⅳ or chronic GVHD of extensive type were significantly higher than those in patients with acute GVHD of grades Ⅰ-Ⅱ or chronic GVHD of limited type (P<0.05-0.01).CONCLUSION: After Allo-HSCT, dynamically monitoring changes of levels of TNF-α, IL-4, and TGF-α may serve as a possible means of predicting the onset of acute or chronic GVHD and may contribute considerably to deciding clinical severity of GVHD.

Objective:To investigate the therapeutic effect of Kangfuxin solution combined with cydiodine on recurrent oral ulcer, and its influence on T lymphocyte subsets and serum interleukin-2(IL-2) and interleukin-6(IL-6).Methods:From December 2017 to December 2019, 296 patients with recurrent aphthous ulcer admitted to the First People's Hospital of Tongxiang were randomly divided into observation group(148 cases) and control group(148 cases) according to the random digital table method.The patients in the control group were treated with cydiodine, while the patients in the observation group were treated with Kangfuxin solution on the basis of the control group.The course of treatment in both two groups was 4 weeks.The changes of T lymphocyte subsets, IL-2 and IL-6 levels, ulcer pain and ulcer diameter before and after treatment were compared.Results:The total effective rate of the observation group(93.92%) was higher than that of the control group(84.46%)(χ 2=6.867, P<0.05). After treatment, CD 4+ [(39.84±1.76)%] and CD 4+/CD 8+(1.82±0.15) in the observation group were higher than those in the control group [(36.51±1.98)% and (1.47±0.12)], while CD 8+ [(22.16±1.46)%] was lower than that in the control group [(24.87±1.37)%], the differences were statistically significant between the two groups( t=15.292, 16.467, 22.166, all P<0.05). After treatment, the serum level of IL-2 [(189.84±17.86)ng/L] in the observation group was higher than that in the control group[(147.82±14.27)ng/L], while the serum level of IL-6[(37.48±6.57)ng/L] was lower than that in the control group [(59.76±12.14)ng/L], the differences were statistically significant between the two groups( t=22.361, 19.636, all P<0.05). The VAS score[(1.36±0.29)points] and ulcer diameter[(1.54±0.38)mm] in the observation group were lower than those in the control group[(2.57±0.41)points, (2.26±0.43)mm]( t=29.312, 15.264, all P<0.05). Conclusion:Kangfuxin solution combined with cydiodine has obvious curative effect in the treatment of recurrent oral ulcer, which can improve the immune function and reduce the reaction, relieve the pain of ulcer and reduce the diameter of ulcer.

Objective: To explore the correlation between blood pressure and urinary phthalandione, MMP, MEP, MnBP, MiBP, PAEs. Methods: Three schools were selected from Shenzhen, China for the present study. A total of 765 firstgrade students of Han ethnicity were recruited voluntarily from the selected schools during September 2016 to June 2017. They were divided into normal blood pressure (BP) group (lower than P90 group) and high BP group (BP≥P90). Linear and Logistic regression models were used to analyze the relationships between blood pressure and urine phthalate metabolite levels. Results: Urinary MMP and MnBP in students of high BP group were significantly higher than that of students in normal BP group(t=13.12, 3.97, P<0.05). Linear regression models showed that Z score increased when MMP and MnBP levels increased(P<0.05). Logistic regression model suggested that the risk of high BP increased with the increment of MMP level adjusting creatinine, sex, age and BMI(OR=1.47, P<0.05). There was no statistical significance in the differences after adjusting many factors including family income and education level of parents(P>0.05). Conclusion Urinary phthalate metabolite levels are positively associated with blood pressure in first-grade children.

By exploring the theory of “the liver is the basis of resistance to fatigue”， it is believed that liver with its physiological function of storing blood and governing the free flow of qi plays an important role in the body's tole-rance to physical fatigue and mental fatigue， and it is also related to the physiological activities of eyes and tendons. The formation of asthenopia is related to the dysfunction of liver， spleen and kidney. The liver plays a key role in the occurrence and development of asthenopia. The deficiency of liver blood and liver dysfunction will cause the abnormal circulation of qi and blood， which leads to the loss of malnutrition of eyes and affects the normal physiological function of eyes. During treatment， we pay attention to nourishing the blood and soothing the liver to nourish the spirit， regulating and tonifying liver qi to stimulate the liver yang， strengthening the spleen and soothing liver to replenish qi and promoting yang， nourishing the liver and kidney to harmonize yin and yang， which are meant to restore the physiological characteristics of liver being yin in form but yang in function， so as to cure asthenopia.

This paper summarized PENG Qinghua's clinical experience in treating dry eye by applying therapeutic method of maintaining with sweet medicinals and restoring the body fluids. It is believed that the spleen earth insufficiency and fluids damage transforming into dryness are the main pathogenesis of the disease， and the basic therapeutic principle is maintaining with the sweet and restoring the body fluids by mainly using sweet medicines. It is advocated to use mild-sweet herbs， such as Baibiandou （Lablab purpureus subsp. purpureus）， Fuling （Smilax glabra Roxb.）， and Yiyiren （Coix lacryma-jobi L.）， to transport spleen earth， so that qi is restored and body fluids are recovered； moderate-sweet herbs， such as Dangshen （Codonopsis pilosula ［Franch.］ Nannf.）， Taizishen （Pseudostellaria heterophylla ［Miq.］ Pax）， Shanyao （Dioscorea oppositifolia L.） and Zhigancao （Glycyrrhiza glabra L.） are suggested to cultivate earth and generate metal， so as to move qi and circulate fluid； sweet-cool herbs， such as Nanshashen （Adenophora triphylla ［Thunb.］ A.DC.）， Beishashen （Glehnia littoralis ［A.Gray］ F.Schmidt ex Miq.）， Yuzhu （Polygonatum odoratum ［Mill.］ Druce）， Tianhuafen （Trichosanthes kirilowii Maxim.） are suggested to nourish yin and increase body fluids， so as to promote fluid production to moisten dryness. In this way， when the source of fluid is restored and the fluid is circulated， the fluid can be produced continuously， which provides new ideas for the treatment of dry eyes with traditional Chinese medicine.

This paper summarized clinical experience of Professor Peng Qinghua in the staged treatment of autoimmune uveitis （AU）. The pathogenesis of AU is always based on root-cause deficiency and manifestation excess， with weakness of healthy qi as the root， and accumulation of wind， dampness and blood stasis as the minifestation. Syndrome differentiation and treatment is usually carried out according to different stages of disease. During the acute stage， deficiency of healthy qi and stagnation of wind-dampness are the key pathomechanisms， so the treatment is to replenish qi and activate blood， dispel wind and remove dampness， and self-made Yiqi Huoxue Qufeng Chushi Decoction （益气活血祛风除湿方） can be used. During remission stage， deficiency of spleen and kidney is the key mechanism， so the treatment is to tonify the spleen and kidney， replenish the essence and brighten the eyes， and self-made Yijing Mingmu Decoction （益精明目汤） can be used. Meanwhile， it was recommened to treat early， prevent and interrupt the disease， commonly combine with Chinese patent medicine Zhengqing Fengtongning tablets （正清风痛宁缓释片）， and promote regulation of living to prevent recurrence.

This paper summarized PENG Qinghua's experience in treating age-related dry eye based on the theory of ministerial fire. Guided by the theory of ministerial fire， it is believed that the key pathogenesis of age-related dry eye is transgression of ministerial fire， and kidney yang deficiency-cold， kidney yin depletion， and spleen-earth insufficiency are the causes of transgression of ministerial fire. The general principle of treatment is to conceal the ministerial fire. For kidney yang deficiency-cold and floating ministerial fire， the treatment should tonify the kidney and warm yang， and return fire to its origin， with Yin Huo Decoction （引火汤）； for kidney yin depletion and frenetic stirring of ministerial fire， the treatment should tonify the kidney and supplement essence， enrich yin and reduce fire， with Sancai Fengsui Pellet （三才封髓丹）； and for spleen-earth insufficiency， and fumigation of ministerial fire， the treatment should strengthen and activate spleen qi， and reinforce soil and hidden fire， with Renshen Huangqi Decoction （人参黄芪汤）.

Based on the theory of "disease involving both dryness and dampness"， it is believed that the complex of dryness and dampness and the mutual stalemate between them produce the disease， forming a pathological state of dampness within dryness and dryness within dampness. The two can occur accompanied by each other， transform into each other， and coexist as a disease. According to the clinical characteristics of sjögren's syndrome-related dry eye disease （SS-DED）， it is believed that its symptoms can reflect the pathological state of coexistence of dryness and dampness， and that "disease involving both dryness and dampness" is the key pathogenesis. The main treatment principles are performing both purgation and tonification， and treating the dryness and dampness simultaneously. The treatment should focus on rectifying qi， fortifying spleen and dispelling dampness， as well as opening orifices， nou-rishing yin and moistening dryness， usually with Shashen Maidong Decoction （沙参麦冬汤） and Xiangsha Liujunzi Decoction （香砂六君子汤） in modifications. The theory of "disease involving both dryness and dampness" is expected to provide ideas for the diagnosis and treatment of SS-DED.

Lectin-like oxidized low-density lipoprotein receptor-1 (LOX-1) have recently been identified to be closely related to the occurrence and development of atherosclerosis (AS). A growing body of evidence has suggested Chinese medicine takes unique advantages in preventing and treating AS. In this review, the related research progress of AS and LOX-1 has been summarized. And the anti-AS effects of 10 active components of herbal medicine through LOX-1 regulation have been further reviewed. As a potential biomarker and target for intervention in AS, LOX-1 targeted therapy might provide a promising and novel approach to atherosclerotic prevention and treatment.
