Objective To investigate the clinical efficacy of a needle knife in treating knee meniscus injury. Methods One hundred patients with knee meniscus injury (112 knee joints) were randomly allocated to treatment and control groups, 50 cases each. The treatment group received needle knife therapy and the control group, an injection of sodium hyaluronate injectio into knee joint cavity. The main clinical symptoms and signs around the knee joint were observed and the knee function score was recorded in the two groups before and after treatment. the clinical therapeutic effects were evaluated in the two groups. Results There were statistically significant differences in pre-/post-treatment main clinical symptom and sign index (pain score, swelling score, activity score and tenderness index score) difference values between the two groups (P<0.05). There were statistically significant differences in the main clinical symptom and sign index difference values at follow-up compared with before treatment between the two groups (P<0.05). There was a statistically significant differences in the knee function score after treatment and at follow-up compared with before treatment in the two groups (P<0.01,P<0.05). There was a statistically significant differences in the knee function score between the treatment and control groups after treatment and at follow-up (P<0.05). Post-treatment excellence rate and total efficacy rate were 94.0%and 100.0%, respectively, in the treatment group and 72.0%and 98.0%, respectively, in the control group. There was a statistically significant differences in post-treatment excellence rate between the two groups (P<0.05). Follow-up excellence rate and total efficacy rate were 96.0% and 100.0%, respectively, in the treatment group and 76.0% and 98.0%, respectively, in the control group.

ObjectiveTo observe andanalyze the clinical efficacy of needle knife treatment for knee meniscus injury from improving knee biomechanical balance and to provide a therapeutic basis and method for clinical practice.MethodOne hundred patients (112 knees) with knee meniscus injury meeting the inclusion criteria were allocated, in order of visits, to observation and control groups, 50 cases each. They were treated with a needle knife and an injection of sodium hyaluronate injectio into knee joint cavity, respectively. Changes in the indices were observed and assessed in the two groups by recording the plantar pressure analysis score and the knee function score before and after treatment and at follow-up. The clinical therapeutic effects were evaluated in the two groups.ResultThemaximum load, time integral difference value and load ratio around the knee joint decreased significantly in both observation and control groups after treatment and at follow-up (P<0.05). The regulating effect on knee joint force balance was better in theneedle knife group than in the control group (P<0.05). The improving effect on knee joint function was significantly better in the observation group than in the control group (P<0.01). The excellence rate was significantly higher in the observation groupthan in the control group after treatment and at follow-up (P<0.05).ConclusionNeedle knife treatment restores the function of the knee joint by loosing focal soft tissues around the knee joint, improving knee joint load imbalance and correcting the mechanical equilibrium around the knee joint in patient with knee meniscus injury. It has a definite curative effect on the disease.

Objective:
To explore the TPO, DUOX2 and DUOXA2 genotypes and phenotypes of children with permanent congenital hypothyroidism(PCH) suspected dyshormonogenesis in Guangzhou, identified and treated at Guangzhou Newborn Screening Center. Six of them were born between 2011 and 2012.
Method:
Retrospectively analyzed the clinical data of 9 children with PCH suspected dyshormonogenesis. Genetic analysis of TPO, DUOX2 and DUOXA2 genes were performed with Sanger sequencing.
Result:
Of the 9 patients, four were identified variants in TPO gene including three cases with biallelic variants and one case with monoallelic variant. Novel c. 1784G>C( p. R595T) variant in TPO was predicted to be damaging by SIFT and PolyPhen-2. Four patients harbored monoallelic known variants in DUOX2 gene and the other one harbored heterozygous known mutation c. 738C>G(p.Y246X) in DUOXA2 gene.Two adolescent patients with biallelic variants in TPO gene showed classical PCH phenotypes with thyroid goiter or nodules. The six patients with monoallelic variant in TPO, DUOX2 or DUOXA2 presented variable phenotypes. Among the 433 578 newborns in the 2011-2012 cohort, there were 156 cases of CH. Six of these cases were PCH suspected dyshormonogenesis, among which 1 case was confirmed TPO biallelic variants and 5 cases were monoallelic variants of TPO, DUOX2, or DUOXA2 genes.
Conclusion
TPO and DUOX2 variants are the common molecular pathogenesis in children with PCH suspected dyshormonogenesis. Monoallelic variants in TPO, DUOX2 or DUOXA2 are associated with PCH and showed wide variability in their phenotypes. The novel variant p. R595T in TPO is probably a pathologic variant. The prevalence of PCH caused by TPO gene defects is rare in Guangzhou.

Objective:
To investigate prospectively molecular and clinical characteristics of infants with congenital hypothyroidism (CH) caused by DUOX2 mutations in Guangzhou.
Methods:
A population-based cohort of 83 patients with CH were recruited based on newborn screening results among 108 899 newborns who were born in Guangzhou between April 1 and September 30 in 2015.Genetic analysis of DUOX2 hotspots(including 11 exons)by PCR-direct sequencing was performed in 52 patients with suspected thyroid dyshormonogenesis (SDH) according to thyroid ultrasound at diagnosis.All the patients were followed up for 3 years.The data of this cohort study(prevalence of CH, detection rate of DUOX2, clinical features) were compared with those of 96 patients with SDH in 2011-2012.
Results:
(1) The incidence of CH in 2015 was 1∶1 312, and 73.5%(61/83 cases) of CH patients were classified as SDH.Compared with those founded in 2011-2012, the incidence of CH was increased (1∶1 312

Objective To study the influence of postnatal age and season of sample collection on congenital hypothyroidism (CH) screening and to determine the appropriate cut-off value. Method From January 2015 to December 2017, neonatal thyroid stimulating hormone (TSH) screening data in Guangzhou were retrospectively analysed. The infants were assigned into four groups according to sampling postnatal age:24~<48 h, 48~<72 h, 3~<7<d and≥7 d, and assigned into another four groups according to their birth seasons. Based on the data of 2015 and 2016, the cut-off value of TSH for hypothyroidism were adjusted. The data of 2017 were used to verify the accuracy of the adjusted cut-off value. The cut-off value was determined based on the receiver operating characteristic (ROC) curve and percentile method. Specificity, sensitivity, positive predictive value (PPV) and negative predictive value (NPV) of the cut-off value were also calculated. Result A total of 459854 newborns were screened from 2015 to 2016. 7329 were positive in preliminary screening, 371 were still positive after recall for re-examination, and 318 were confirmed with CH eventually. The optimal TSH cut-off value calculated using ROC curve was 9 mIU/L, with a percentage of 98.7. The cut-off value with sampling time≥48 h was set to 9 mIU/L in spring, summer and autumn, and 10 mIU/L in winter. The cut-off of sampling time 24~<48 h was set to 10 mIU/L in all seasons. The data of 264993 newborns screened in 2017 were verified using the adjusted cut-off value. The overall positive rate was reduced from 1.27%to 1.02%, and the PPV was increased from 6.07%to 7.58%without adding false negative cases. Conclusion Adjusting cut-off values of TSH for CH screening according to postnatal age and season can effectively reduce false positive rates.

With human placed in the whole nature, by following the biologic evolution path, the property of channel structure for "imprinting template" in meridian andwas explored with supramolecular chemistry. In the history of biologic evolution, each molecule in "molecule society" gradually developed into various highly-ordered supramolecular bodies based on self-identification, self-assembly, self-organization, self-replicating of"imprinting template", and thereby the original biochemical system was established, and finally evolved into human. In the forming process of supramolecular bodies, the channel structure of"imprinting template" in guest supramolecular bodies would be kept by host supramolecular bodies, and communicate with the outside to exchange materials, energy, information, otherwise life phenomenon could not continue, for which it was the chemical nature of biolo-gical supramolecular bodies for body to develop meridian. Therefore, the human was a gigantic and complicated supramolecules body in biological nature, and possessed the supramolecules "imprinting template" at each stage of evolution, for which the meridians were formed. When meridians converged, acupoints appeared; when acupointsconverged,appeared. With the promotion of the blood from heart, according to"imprinting template", the guest supramolecular bodies and host meridian produced-analysis, which was the-phenomenon of guest in meridian. It presented asimage of physiology and pathology as well as action regularities of medication and acupuncture tolerance, by which current various meridian viewpoints could be explained and propose the hypothesis of meridian supramolecular bodies. The meridian and its phenomenon was decide by its "imprinting template" of supramolecular bodies and self-reaction regularities, which abided through the living nature. This was the substance for meridian biology.

Ganjiang (Zingiberis Rhizoma, ZR) and Jiangtan (Carbonized Zingiberis Rhizoma, CZR) have
long been used in traditional Chinese medicine (TCM) with a rich history in the treatment of
various ailments. While ZR and CZR obviously stem from the same botanical source, their attributes, chemical compositions, pharmacological behaviors, and clinical applications are different owing to variations in the extent of drying and processing they undergo. In this paper,
data pertaining to ZR and CZR were retrieved from databases including China National
Knowledge Infrastructure (CNKI), PubMed, Web of Science, and Google Scholar. These
sources were scrutinized to elucidate the distinctions between ZR and CZR arising from carbonization processing in terms of their ethnopharmacology, quality control, chemical compositions, biological activities, pharmacological mechanisms, and clinical uses. In this study,
a total of 56 chemical constituents were identified and isolated from ZR and CZR, which primarily encompassed volatile oils, gingerols, and diphenylheptane compounds. CZR's pharmacological effects include hemostatic, anti-oxidant, analgesic, antibacterial, anti-cancer,
and other biological activities. ZR has pungent and warm properties. It is a Yang-supplementing herbal medicine for ailments exacerbated by cold or damp climatic influences. CZR is a
product of ZR after undergoing high temperature, with diminished intensity of its pungent
and warm attributes. This change leads to a more gradual treatment efficacy, renowned
hemostatic effects and its ability to gently invigorate the spleen and effectively alleviate diarrhea. Currently, research on the pharmacological mechanism of CZR is mainly focused on the
effects of CZR on coagulation and fibrinolysis. Although the healing effect of CZR has long
been known, and some correlation has been found between the changing composition and
the changing color of the decoctions, people still lack relatively clear processing mechanisms
to reflect the characteristics and specific quality standards of the ingredients of CZR's hemostatic effect. This review provides a systematic summary on quality control, chemical composition, ethnopharmacology, and pharmacology of CZR, offering novel perspectives for advancing the exploration of additional carbonized herbal medicine and fostering their application in clinical settings
