To address the common clinical problems associated with warm needling moxibustion, such as burns, bending of needle handles, and the inability to perform moxibustion during oblique needling, an adjustable warm needling moxibustion device is designed and has been granted a national patent. This device consists of five components: a moxa cylinder, an adjustable arm, a supporting tube, a temperature alarm, and a fixing strap. It allows infrared heat radiation from the moxa to pass through while blocking falling ash, thereby ensuring therapeutic efficacy and preventing burns. The device accommodates both perpendicular and oblique needling angles and adapts to various body positions, effectively avoiding deformation of the needle handle. It is easy to operate and offers high safety.

The pregnant woman was 39 years old，G2P1，a fetal goiter was found at 25 weeks at the Second Xiangya Hospital of Central South University，and thyroid function was normal during the pregnancy. Amniocentesis revealed the presence of two DUOX2 mutations in fetal DNA：c.3340delC（P.L1114Sfs56）in exon 25 and c.2654G＞A（p.R885Q）in exon 20，which were determined to be heritable by familial genetic testing. Many fetal and neonatal ultrasounds have shown goiter，rich blood flow in the parenchyma and low postnatal thyroid hormone levels led to the diagnosis of congenital hypothyroidism. The patient was given L-thyroxine 30 μg/d. After 3 months of follow-up，the thyroid function was normal without developmental problems.

Objective To investigate the therapeutic effect and mechanism of MCC950 on benzalkonium chloride-in-duced dry eye(DED)in rats.Methods Among 60 male SD rats,50 rats were treated with 20 g·L-1 benzalkonium chlo-ride solution 3 times a day in both eyes to induce DED model,and a significant decrease in tear secretion was regarded as a successful modeling,and the remaining 10 rats were regarded as the control group.DED rats were randomly divided into 5 groups:DED,DED+10MCC950,DED+50MCC950,DED+100MCC950,and DED+500MCC950 groups,and were given 0.2 mL of 0,10,50,100,and 500 μmol·L-1 MCC950 in both eyes for two weeks,and then examined the amount of tear secretion,corneal histopathology(HE staining),reactive oxygen species(ROS),and inflammation factors(NLRP3,Caspase-1,IL-1β,IL-6).Results The tear secretion of rats in the DED group was significantly lower than that of the control group(P＜0.05).Except for the DED+10MCC950 group,the tear secretion of rats in different concentrations of MCC950 treatment groups was increased and positively correlated with the MCC950 dose(all P＜0.05).HE staining of the cornea showed that compared with the control group,the cornea of the DED group was significantly thinner,the arrange-ment of surface cells was disorganized,the number of cells was significantly reduced,and a large number of"vacuole"-like structures appeared;the corneal stroma was disorganized and sparsely structured.The degree of histopathological changes in the cornea of rats treated with different concentrations of MCC950 decreased with the increase of the concentration of MCC950.Compared with the control group,the relative expression level of ROS in the DED group of rats was significantly increased(P＜0.05).In each MCC950 treatment group,as the concentration of MCC950 increased,the relative expression level of corneal ROS staining in rats gradually decreased,showing a concentration-dependent effect(all P＜0.05).Com-pared with the control group,the levels of NLRP3,IL-1 β,Caspase-1 and IL-6 were significantly increased in the DED group(all P＜0.05).The levels of various inflammatory factors were dose-dependently reduced in the MCC950 treatment groups(all P＜0.05).Conclusion MCC950 can reduce oxidative stress and inflammation and improve the symptoms of benza-lkonium chloride-induced DED in rats by inhibiting the activation of NLRP3 inflammatory vesicles.

Objective To determine the diagnosis value of urinary albumin(mAlb)/creatinine(Ucre) ratio in random urine from patients with early diabetic nephropathy.Methods From March 2015 to December 2016,98 case with simple diabetes and early diabetic nephropathy in Ankang Hospital of Traditional Chinese Medicine were selected,including 47 cases with simple diabetes and 51 cases with early diabetic nephropathy.And 60 healthy people were selected as control group.The mAlb and mAlb/Ucre ratios in morning urine,postprandial urine and random urine were detected for three times in three days,and the resluts were calculated and analyzed.Results In early diabetic nephropathy group,the mAlb concentration varied during different time periods,mAlb in morning urine [(60.5 ± 27.1)mg/L] and postprandial urine [(60.7 ± 26.7)mg/L] were significantly increased compared with that in random urine [(40.9 ± 25.1) mg/L] (F =9.551,P =0.000).The MAlb/Ucre ratios were stable in morning urine,postprandial urine and random urine of each period (P ＞ 0.05).The positive rate of mAlb/Ucre ratio was sharply higher than mAlb alone in random urine (90.2％ vs.62.7％).No statistically significant difference showed in positive rates of mAlb/Ucre ratio in subjects from different groups(the positive rate of morning urine specimen was 92.2％;postprandial urine 88.2％;random urine 90.2％,P ＞ 0.05).Conclusion Positive rate of mAlb/Ucre ratio changed slightly during different test periods,and is superior to mAlb alone in clinic application.Additionally,the positive rate of mAlb/Ucre ratio in random urine could serve as an indicator in early screening of early diabetic nephropathy.

Objective To evaluate the effect of dexmedetomidine pretreatment on the expression of mitochondrial transcription factor A ( TFAM) and succinate dehydrogenase ( SDHA) during lung ischemia-reperfusion ( I∕R) in mice. Methods Twenty-four clean-grade healthy male C57BL∕6J mice, aged 8-10 weeks, weighing 18-22 g, were divided into 3 groups ( n=8 each) using a random number table method:sham operation group ( group S ) , lung I∕R group ( group I∕R ) and dexmedetomidine pretreatment group ( group D) . In I∕R and D groups, lung I∕R was induced by clamping the left pulmonary hilum for 60 min followed by 120-min reperfusion in anesthetized mice. The chest was only opened, but the left pulmonary hilum was not occluded in group S. Dexmedetomidine 25μg∕kg was intraperitoneally injected at 30 min be-fore ischemia in group D, while the equal volume of normal saline was given instead of dexmedetomidine in I∕R and S groups. The mice were sacrificed at 120 min of reperfusion, and lungs were removed for determi-nation of wet∕dry weight ratio ( W∕D ratio) , cell apoptosis ( by TUNEL) and expression of TFAM and SDHA mRNA in lung tissues ( by real-time polymerase chain reaction ) and for examination of the pathological changes of lung tissues. The apoptosis index was calculated. Results Compared with group S, the W∕D ratio, apoptosis index and lung injury scores were significantly increased, and the expression of TFAM and SDHA mRNA was down-regulated in I∕R and D groups ( P<0. 05) . Compared with group I∕R, the W∕D ra-tio, apoptosis index and lung injury scores were significantly decreased, and the expression of TFAM and SDHA mRNA was up-regulated in group D ( P<0. 05) . Conclusion The mechanism by which dexmedeto-midine pretreatment attenuates lung I∕R injury is related to up-regulating the expression of TFAM and SDHA in mice.

To assess the application of Keratograph 5M in evaluating tear film and meibomian gland function in patients with dry eye.A total of 144 eyes were recruited in the study, in which 72 eyes were from patients diagnosed with dry eye and 72 eyes were from healthy subjects. All subjects finished following tests or examinations:ocular surface disease index (OSDI) to evaluate eye symptoms; Keratograph 5M examination to obtain tear meniscus height (TMH), noninvasive tear break-up time (NIBUT) including first NIBUT (NIBUT-Fir) and average NIBUT (NIBUT-Ave), and infrared meibography; and fluorescein sodium staining to obtain fluorescein tearbreak-up time (FBUT).Dry eye group had higher OSDI score than healthy control group, but its TMH, NIBUT-Fir and NIBUT-Ave were lower than those in healthy control group (all<0.01). Total meiboscore in dry eye group was higher than that in healthy control group (<0.01), and it showed a significant correlation with NIBUT-Fir and NIBUT-Ave (=-0.449 and -0.398,<0.01), but no correlation with ages was observed (=0.031,>0.05). The NIBUT-Fir and NIBUT-Ave showed a significant correlation with FBUT (=0.833 and 0.727,<0.01).Keratograph 5M is a convenient, accurate and non-invasive method to assess the function of tear film and meibomian gland, and the new meibography scoring system can evaluate the function of meibomian gland objectively and succinctly.
